Nasdaq listing plans for Anthropic took a concrete step on Sunday 13 September 2026, when Business Insider reported that the Claude developer had picked Nasdaq for an initial public offering it hopes to complete in October. Reuters carried the report 22 minutes later. Bloomberg confirmed it with its own source about two hours after Business Insider, under the headline “Anthropic Said to Choose Nasdaq for Much-Anticipated IPO Listing”. Anthropic did not respond to requests for comment, and Nasdaq declined to comment.
The exchange sounds like a detail next to a raise that could reach $100 billion. It is more than that. A Nasdaq listing is the only way into the Nasdaq-100 index, and since May that index has let the largest new listings join after 15 trading days instead of waiting months. That rule carried SpaceX into the index on 7 July. When index funds must buy a stock whether or not anyone chooses to, the venue decides how soon that buying starts. That matters for anyone following artificial intelligence as an investment theme, not just for traders.
This article explains what was reported and what the Nasdaq listing unlocks through Nasdaq’s Fast Entry rule. It also covers how the opening auction works, why Facebook’s 2012 debut still hangs over the exchange, and what the choice does not change. We have covered the rest of the story separately: the IPO timetable’s shift toward mid-October, Nvidia’s talks to anchor the offering, the circular financing questions those talks raise and OpenAI’s decision not to list in 2026.

What Was Reported About Anthropic's Nasdaq Listing
Four outlets carried the story on Sunday, but only two had their own source. Business Insider’s Katie Roof broke it at 16:01 UTC, citing “a person familiar with their plans”. Reuters rewrote her report at 16:23 UTC without adding a source of its own. Bloomberg’s Bailey Lipschultz published at 18:03 UTC, citing “a person familiar with the matter”. That makes Bloomberg the only outlet besides Business Insider with independent confirmation of the Nasdaq listing.
| Outlet | Published (UTC, 13 Sep) | Sourcing | What it added |
|---|---|---|---|
| Business Insider (Katie Roof) | 16:01 | “A person familiar with their plans” | Broke the Nasdaq choice, the October target and the 15-day disclosure rule |
| Reuters (Ananya Palyekar) | 16:23 | Cited Business Insider | A one-sentence rewrite, no independent confirmation |
| The Next Web (Ana-Maria Stanciuc) | 17:14 | Cited Business Insider | The index angle and the contrast with OpenAI |
| Bloomberg (Bailey Lipschultz) | 18:03 | “A person familiar with the matter” | Its own confirmation, the raise “as much as or more than SpaceX” and the $160.6 billion US IPO total |
Business Insider’s report
Business Insider said the company “has been targeting an October listing” and “has given Nasdaq another big win”. It put SpaceX’s value at listing at $1.75 trillion and said “some estimates have put Anthropic at $2 trillion, though that figure has not yet been finalized”. It also described the stakes for the two exchanges: “The record-setting size of these IPOs, combined with the dearth in tech listings in recent years, has made winning this competition particularly valuable. Both hope to be seen as the home for future AI IPOs.”
What Bloomberg added
Bloomberg added four points Business Insider did not carry. Anthropic “is seeking to raise as much as or more than SpaceX” in an IPO “that could take place as soon as October”. Nasdaq has hosted “four of the largest US IPOs” this year, including SpaceX and SK Hynix. US listings have raised $160.6 billion in 2026, excluding blank-check companies, which is the most since 2021. And Anthropic’s annualised revenue is running above $65 billion, “up more than sevenfold from its pace at the end of last year”.
What nobody has confirmed
Neither company has confirmed the Nasdaq listing. What Anthropic has confirmed is that it confidentially submitted a draft registration statement to the Securities and Exchange Commission on 1 June. The valuation, the raise, the share count, the ticker and the date all come from people familiar with the plans, not from a prospectus. The Next Web put it plainly: “Every valuation attached to it so far has come from people briefing reporters rather than from a prospectus.”
Why a Nasdaq Listing Opens the Fast Entry Door
The Nasdaq-100 only admits companies listed on Nasdaq. Business Insider called a listing on the exchange “a prerequisite for inclusion in the Nasdaq 100 Index”, and The Next Web called that “the part that does matter”. Until this year, even an eligible giant still had to wait. What changed was a methodology rule Nasdaq adopted in March 2026, and it is the main practical difference an Anthropic Nasdaq listing makes.
The old wait: seasoning and an annual reshuffle
Under the old rules, new members were normally added at the annual reconstitution in December. They also needed a “seasoning period” of at least three months of trading, according to a briefing from the law firm Ashurst. A company had to show average daily traded value of at least $5 million over three months as well. So a giant new listing could trade for most of a year before index funds had to own it, even if it was bigger than most of the index.
The Fast Entry rule, clause by clause
Nasdaq opened a consultation in February, with comments due by 27 February, and adopted the rule in March, effective 1 May 2026. A newly listed company whose entire market capitalisation ranks within the top 40 current members is announced as a Fast Entry addition with at least five trading days’ notice. It joins after 15 trading days and is exempt from the seasoning and liquidity tests. No existing member has to be removed. The index simply runs above 100 names until the next reconstitution.
| Rule | Nasdaq-100 before May 2026 | Nasdaq-100 Fast Entry | S&P 500 (unchanged in June) |
|---|---|---|---|
| Exchange | Nasdaq only | Nasdaq only | Any eligible US exchange |
| Wait after listing | At least three months, usually until December | 15 trading days | At least 12 months |
| Size test | Ranked at reconstitution | Top 40 current members by entire market value | Market value plus float and liquidity tests |
| Liquidity test | Three-month daily value of at least $5 million | Exempt | Applies |
| Minimum free float | Below 10% excluded | None; below 20% gets reduced weight | Investable weight factor of at least 0.10 |
| Profitability | Not required | Not required | Positive GAAP earnings required |
| Notice | Annual announcement | At least five trading days | Index committee announcement |
Two amendments that matter more than the headline
Two smaller changes make the rule work for a company like Anthropic. First, eligibility and ranking now use a company’s entire market capitalisation, including unlisted shares, not just the shares that trade. Second, the old exclusion of companies with less than 10% free float has gone. A company floating less than 20% has its weight set at three times its free-float value instead, capped at its full market value. So a very large company floating a few per cent of its shares still qualifies, but it enters at a fraction of its headline weight.
SpaceX was the test case
SpaceX was the first giant to use the route. It priced at $135 a share on 11 June and began trading on 12 June. Nasdaq announced on 26 June, its 11th trading day, that SpaceX would join the Nasdaq-100 before the market opened on 7 July, The Motley Fool reported. That was 25 calendar days after its first trade. JPMorgan estimated the inclusion could trigger $4.3 billion of buying. Even so, SpaceX entered at a weight of only about 1%, because the index weights by free float and only a small slice of its shares trade.
The S&P 500 said no
The index with far more money behind it did not follow. S&P Dow Jones Indices opened a consultation on 30 April on cutting the S&P 500’s 12-month seasoning period to six months for megacap IPOs and waiving its profitability and float tests. On 4 June it said “no changes will be made to the eligibility criteria including financial viability screens, seasoning period, or minimum IWF”. It added that exceptions “should not be granted solely based on market capitalization”. So Anthropic waits at least 12 months for the S&P 500 on either exchange. Only a Nasdaq listing offers a major index within weeks.
Trading days before a new listing can join each index
Assumes 21 trading days a month. Bar width is trading days divided by 252.
How Much Passive Money a Nasdaq Listing Can Pull In
Index inclusion is where a Nasdaq listing turns into buying. The Next Web described index inclusion as something that “pulls passive money in behind a stock without anyone deciding to buy it”. A fund that tracks an index has to hold what the index holds, at whatever the price is on the day the stock is added.
The Nasdaq-100 money pool behind a Nasdaq listing
When it announced Fast Entry on 30 March, Nasdaq said the Nasdaq-100 is “tracked by more than 200 investment products with over $600 billion in assets under management globally”, Yahoo Finance reported. The two largest, the Invesco QQQ ETF and the Invesco Nasdaq 100 ETF, managed a combined $570 billion in July, according to The Motley Fool. Goldman Sachs analysts estimated the rule change could trigger up to $60 billion of forced buying across the Nasdaq-100, Fortune reported.
What SpaceX’s inclusion implies for a Nasdaq listing
JPMorgan’s $4.3 billion estimate for SpaceX was about 5% of the $85.7 billion SpaceX raised including its overallotment option. Nobody has published an equivalent estimate for an Anthropic Nasdaq listing. The number will depend on Anthropic’s market value on its first days of trading and, above all, on its free float, which sets its weight. Neither will be known until the prospectus fixes the number of shares on offer.
Why the S&P 500 decision cuts both ways
The S&P 500 pool is far larger. Fortune, citing S&P Dow Jones Indices, put the money indexed or benchmarked to the S&P 500 at $20 trillion as of December 2024, about $13 trillion of it passive. That passive figure alone is almost 22 times the $600 billion Nasdaq cites for its index products. Critics of fast inclusion say forcing retirement savings into a thinly traded new stock is the problem. “They had to bend the rules to get into the Nasdaq index—they would never qualify normally,” the governance expert Nell Minow told Fortune.

Anthropic's Nasdaq Listing and the Opening Auction
Business Insider pointed to one practical difference between the exchanges: “market-maker mechanics”. The two venues “have different processes for determining the opening price on the first day of trading, and high-volume IPOs can cause delays and confusion”. For a Nasdaq listing, that process is called the IPO Cross.
How the IPO Cross opens a Nasdaq listing
Nasdaq introduced the IPO Cross on 30 May 2006. Its factsheet describes four stages. From system start-up, Nasdaq accepts orders, which can still be cancelled. A display-only period of 10 minutes then publishes an indicative clearing price and order imbalance data, updated every second. Next comes a pre-launch period that “will not have a defined minimum or maximum time period”. Finally, the cross “begins once the lead underwriting firm communicates to Nasdaq that they are ready to proceed”. The opening price is the one that executes the most shares, with ties broken toward the issue price.
| Stage | What happens | Who decides |
|---|---|---|
| 1. System start-up | Orders accepted and shown on depth-of-book feeds; orders can be cancelled | Automatic |
| 2. Display-only period | Indicative clearing price and imbalance published every second for 10 minutes | Automatic |
| 3. Pre-launch period | No fixed length; continues if there is an order imbalance or volatility | Lead underwriter, with Nasdaq |
| 4. IPO commencement | Single-price cross runs, opening price published, regular trading begins | Nasdaq IPO officer opens the stock |
The underwriter holds the trigger
That last stage matters for Anthropic’s banks. On a Nasdaq listing, the lead underwriter decides with Nasdaq when trading opens. The cross will not run while there is a market order imbalance or detected volatility; the pre-launch period simply continues “to allow for additional price discovery”. The Next Web reports that Morgan Stanley and Goldman Sachs are leading the deal. For an offering expected to draw heavy demand, the moment of the first trade is a judgement call for those banks, not a fixed time on a clock.
How the NYSE opens a new listing
The New York Stock Exchange opens new listings through a designated market maker, a firm assigned to the stock that manages the opening auction on its trading floor with input from the underwriters. Business Insider’s point was not that one process is better than the other. Both look for a single price where buy and sell orders meet. The difference is who runs the auction and how much of it is automated, which is exactly the part that failed on Nasdaq in 2012.
Facebook 2012: The Nasdaq Listing Nobody Has Forgotten
Every large Nasdaq listing is measured against Facebook’s debut on 18 May 2012. Business Insider mentioned it in one line, “Nasdaq experienced technical issues on the first day of Facebook’s 2012 IPO”. The Next Web called it “still the cautionary example whenever a listing of this size arrives”.
What the SEC found
The Securities and Exchange Commission published specific findings when it charged Nasdaq in May 2013. “A design limitation in NASDAQ’s system to match IPO buy and sell orders caused disruptions to the Facebook IPO,” it said. The cross fell 19 minutes behind the orders Nasdaq was receiving. More than 38,000 marketable Facebook orders placed between 11:11 a.m. and 11:30:09 a.m. were left out of the cross, and another 30,000 were “stuck”.
| SEC finding on the Facebook debut | Figure |
|---|---|
| Date of the IPO | 18 May 2012 |
| How far the cross fell behind incoming orders | 19 minutes |
| Marketable orders left out of the cross | More than 38,000, placed 11:11 a.m. to 11:30:09 a.m. |
| Orders described as “stuck” | 30,000 |
| Penalty paid by Nasdaq | $10 million, “the largest ever against an exchange” |
The penalty
Nasdaq agreed to pay a $10 million penalty and to change its procedures for the cross. “This action against NASDAQ tells the tale of how poorly designed systems and hasty decision-making not only disrupted one of the largest IPOs in history, but produced serious and pervasive violations of fundamental rules governing our markets,” said George S. Canellos, then co-director of the SEC’s Division of Enforcement.
Why the process now looks different
The current process, as Nasdaq describes it, separates the display period, the underwriter’s launch decision and the cross itself, and it sets no deadline for the launch. SpaceX’s debut in June put that process under far heavier demand than a normal listing. CNBC’s account of the day focused on the price: the stock closed around $161, up 19% from its $135 offer price. A clean first day for an Anthropic Nasdaq listing is part of what Nasdaq is selling.
Nasdaq vs NYSE: The Race to Win the AI Nasdaq Listing
Business Insider described two exchanges that “both hope to be seen as the home for future AI IPOs”. The Next Web said the venues are “competing less for the fees than for the right to be seen as the natural home of every AI listing that follows”. Historically, the NYSE “has won many of the largest listings”, Business Insider noted, “but Nasdaq has remained strong in tech, with large listings including Cerebras and Rivian”. We covered Cerebras’s IPO filing in April. In 2026, Nasdaq has had the better year.
SpaceX and SK Hynix
SpaceX raised an initial $75 billion when it priced on 11 June, then the biggest IPO ever, and $85.7 billion once underwriters exercised the overallotment option, CNBC reported. Bloomberg puts the offering at $86.3 billion. A month later, SK Hynix listed American depositary receipts on Nasdaq. It priced 177.9 million of them at $149 each to raise $26.5 billion, Quartz reported, the largest US share sale ever by a foreign company. That beat the $25 billion Alibaba raised in 2014.
Offering size, in billions of dollars
Bar width is the offering divided by $100bn. Anthropic’s figure is a reported target, not a filed range.
Two listings, 70% of the year’s IPO money
On Bloomberg’s own figures, SpaceX’s $86.3 billion and SK Hynix’s $26.5 billion add up to $112.8 billion. That is about 70% of the $160.6 billion US listings have raised so far this year. A $100 billion Anthropic raise on its own would equal 62% of that year-to-date total. Winning the Anthropic Nasdaq listing would give one exchange the three largest offerings of a record year.
Walmart’s switch
The contest is not only about new listings. Walmart moved its shares from the NYSE, where it had traded since 1 October 1972, and began trading on Nasdaq on 9 December 2025. The company said the move followed “an evaluation of several factors, including trading execution, brand alignment, and a shared focus on technology-driven innovation”. When an existing giant picks a Nasdaq listing on those grounds, it becomes part of the pitch to the next AI company.
| Company | Date | Type | Size | Why it mattered |
|---|---|---|---|---|
| Walmart | 9 Dec 2025 | Transfer from the NYSE | No capital raised | A 53-year NYSE company cited “trading execution” and technology |
| SpaceX | 12 Jun 2026 | IPO | $75bn initial, $85.7bn with overallotment | First Fast Entry addition to the Nasdaq-100, on 7 July |
| SK Hynix | 10 Jul 2026 | ADR listing | $26.5bn | Largest US share sale by a foreign company |
| Anthropic | October target (reported) | IPO | Up to about $100bn (reported) | Fast Entry candidate if it ranks in the top 40 |
The fee is not the prize
The fee for a Nasdaq listing is small change. Nasdaq’s January 2026 initial listing guide sets a flat entry fee of $325,000 on the Nasdaq Global Select Market, including a $25,000 application fee. Against a raise of up to $100 billion, that is 0.000325% of the proceeds. The value to Nasdaq lies in what follows: trading in the shares, the products built on the Nasdaq-100, and being seen, in Business Insider’s words, as “the home for future AI IPOs”.
What a Nasdaq Listing Does Not Change
The most important line in Business Insider’s report may be the least exciting one: “In terms of how Anthropic ultimately trades, this decision likely matters little. There isn’t a definitive answer on whether companies perform better on one exchange versus another.”
The valuation is set by buyers, not the venue
The exchange does not set the price. The $2 trillion figure is an estimate that “has not yet been finalized”, according to Business Insider. Anthropic’s last priced round was its $65 billion Series H in May, at a $965 billion post-money valuation. Reaching $2 trillion would take a further 2.07-fold rise from that round. The Series H itself came after a 2.54-fold rise from the $380 billion Series G in February.
Anthropic’s valuation marks, in billions of dollars
Bar width is the valuation divided by $2,000bn. Step-ups: 2.08x, 2.54x and 2.07x.
The governance stays the same
A Nasdaq listing does not change how Anthropic is run either. Anthropic is a Delaware public benefit corporation. Its Long-Term Benefit Trust holds a special class of shares, Class T, that lets it elect directors, and it was set up to elect a majority of the board within four years. The trustees now include the former Federal Reserve chair Ben Bernanke, who joined in July 2026, according to Anthropic. How that structure is presented to public investors will be one of the most closely read parts of the prospectus, whatever the venue.
The revenue and the risks stay the same
The business underneath does not change with the venue. Anthropic’s run rate rose from about $9 billion at the end of 2025 to $65 billion by the end of July, according to figures Reuters reported. At $2 trillion, that is about 30.8 times the run rate. The prospectus will also have to set out the risk factors of a frontier AI company, from model misuse and cybersecurity to its reliance on a small number of compute suppliers. None of that reads differently on a Nasdaq listing than it would on the NYSE.
| What the venue changes | What the venue does not change |
|---|---|
| Access to the Nasdaq-100, possibly within 15 trading days | S&P 500 eligibility, which needs 12 months and profits on any exchange |
| The opening auction: Nasdaq’s IPO Cross, launched by the lead underwriter | The valuation, which buyers set in the book-build |
| Which exchange hosts the listing ceremony and the trading data | Revenue, losses, compute commitments and risk factors |
| A $325,000 entry fee | The public benefit corporation structure and the trust’s board rights |
Anthropic's IPO Timeline After the Nasdaq Listing Decision
The Nasdaq listing decision is one step on a timetable that has already moved once. Reuters reported on 4 September that marketing had slipped to mid-October at the earliest, with completion still aimed at the days before the 3 November midterm elections. Our analysis of that shift covers the calendar in detail. The Nasdaq listing adds two clocks to watch.
The 15-day disclosure rule
Anthropic submitted its draft registration statement confidentially. Under the SEC’s nonpublic review process, an issuer must confirm it “will publicly file its registration statement and nonpublic draft submissions at least 15 days prior to any road show”. Business Insider flagged the same deadline. A roadshow starting in mid-October therefore implies a public filing by around the end of September. That is when the first audited numbers anyone can check will appear.
The Fast Entry clock after the first trade
If Anthropic lists in late October and its market value ranks in the Nasdaq-100’s top 40, Fast Entry starts a second clock. Nasdaq would announce the addition with at least five trading days’ notice and add the stock after 15 trading days, roughly three calendar weeks. After a late-October Nasdaq listing, index funds would be buying by around the middle of November. That assumes the listing happens on schedule, which nothing yet guarantees.
| Date | Event | Status |
|---|---|---|
| May 2026 | $65 billion Series H at $965 billion post-money | Confirmed by Anthropic |
| 1 June 2026 | Confidential draft registration statement submitted | Confirmed by Anthropic |
| 4 September | Marketing pushed to mid-October at the earliest | Reported by Reuters |
| 11 September | Nvidia in discussions to anchor with up to $10 billion | Reported by Reuters |
| 13 September | Nasdaq chosen as the venue | Reported by Business Insider and Bloomberg |
| Around late September | Public filing, at least 15 days before the roadshow | Implied by the SEC rule |
| Mid-October at the earliest | Roadshow | Reported |
| Before 3 November | Pricing and first trade | Reported target |
| About 15 trading days after listing | Possible Nasdaq-100 Fast Entry | Depends on market value rank |
How little time is left
From 14 September to 3 November is 50 days. The confidential filing is already 105 days old. Inside those 50 days, Anthropic has to file publicly, wait at least 15 days, run a roadshow, price the shares and open its Nasdaq listing through the IPO Cross. Any slip in the public filing pushes every later step, which is why the filing date is the next number to watch.
Why Anthropic's Nasdaq Listing Lands in a Week of Safety Warnings
The timing is awkward. Bloomberg noted that the IPO preparations came as Sam Altman, Dario Amodei and Elon Musk “on Saturday all voiced the need to slow the pace of AI development due to escalating risks from the technology”. The Next Web framed it more sharply: the company preparing to ask public markets for a valuation is the company one of the loudest warnings came from.
OpenAI chose the opposite
Altman told Fortune that OpenAI would not go public this year. “Given everything happening with safety, right now would be an ill-advised moment to go public, and we don’t feel pressure on that,” he said, adding: “I would say not 2026.” The Next Web summed up the contrast: the two companies “have reached opposite conclusions from an almost identical set of facts”. We covered Altman’s reasoning in detail.
Amodei’s call to pace the frontier
Amodei’s essay, “We Must Pace the Frontier”, called on the industry to slow frontier model development so that safety work can catch up, and Musk backed the proposal. Our coverage of the essay and of Musk’s support sets out what was actually proposed. A chief executive asking rivals to slow down while his own company prepares a Nasdaq listing is not a combination investors are used to.
The extinction-risk post
Business Insider also tied the attention on AI risk to “a viral tweet from a former Anthropic employee, warning of a greater than 10% human extinction risk”. We looked at that warning and at the language in Anthropic’s own safety documents. None of it changes the mechanics of a Nasdaq listing. All of it will shape the questions asked on the roadshow.
What to Watch Before the Nasdaq Listing
The Nasdaq listing is settled, if the reports are right. Five other things will tell you more about how the offering goes.
The public filing behind the Nasdaq listing
The public registration statement will set the share count, the offer size and the free float. It will also show audited revenue and losses and the governance terms. Watch the float especially: under Fast Entry it decides how much weight the stock carries in the Nasdaq-100 and so how much index funds buy.
Confirmation of the exchange
Nasdaq declined to comment on Sunday, and Anthropic did not respond. The prospectus cover normally names the exchange and the proposed ticker, so the public filing is where a Nasdaq listing would be confirmed in writing.
The anchor investor
Reuters reported on 11 September that Nvidia is in discussions to invest up to $10 billion as an anchor. Our analysis explains what an anchor commitment is, and what it is not. If it goes ahead, expect it in the prospectus as an indication of interest.
The Fast Entry announcement
If Anthropic ranks in the top 40, Nasdaq must announce the addition at least five trading days in advance. For SpaceX, the announcement came on its 11th trading day. An announcement for Anthropic would be the first hard signal of when index buying starts.
Float increases after the lock-up
As locked-up shares are released and more of the company trades, its index weight can rise, and tracking funds buy again. The Motley Fool made that point about SpaceX: “If more shares become publicly available, the stock’s weight will likely rise.” The same applies to an Anthropic Nasdaq listing.
What Anthropic's Nasdaq Listing Means for Businesses Using Claude
For most companies that use Claude, the Nasdaq listing changes nothing directly. The effects come later, and they come from being a public company rather than from where the shares trade.
Nothing changes for the product
A Nasdaq listing does not change Claude’s terms, prices or availability. The IPO raises money and creates a market for Anthropic’s shares. It is not a product decision, and none of the reporting suggests any change to how Claude is sold.
The prospectus is due-diligence material
For companies that depend on Claude, the public filing will be the most detailed account yet of Anthropic’s finances, compute commitments and risk factors. Procurement and risk teams that now rely on press reports and funding announcements will be able to read audited figures instead.
Quarterly reporting is the long-term change
Once listed, Anthropic will report results every quarter and answer to public shareholders as well as its trust. Over time, that pressure is more likely to affect pricing and priorities than the choice between Nasdaq and the NYSE.
Frequently Asked Questions About Anthropic's Nasdaq Listing
Has Anthropic confirmed a Nasdaq listing?
No. Business Insider and Bloomberg reported it, each citing a person familiar with the plans. Anthropic did not respond to requests for comment, and Nasdaq declined to comment.
When is the Anthropic IPO expected?
Reports point to October, with completion aimed at the days before the 3 November midterm elections. Nothing is fixed until Anthropic files publicly and sets a price range.
How much could Anthropic raise?
Bloomberg said Anthropic is seeking to raise “as much as or more than SpaceX”, which raised $85.7 billion including its overallotment. Reuters has reported a raise of up to about $100 billion at a valuation of around $2 trillion, with plans still under discussion.
Could Anthropic join the Nasdaq-100 quickly?
Possibly. Under Fast Entry, a new Nasdaq listing that ranks within the index’s top 40 by market value is added after 15 trading days. SpaceX joined 25 calendar days after its debut.
Will Anthropic join the S&P 500 soon?
Not soon. In June, S&P Dow Jones Indices kept its 12-month seasoning period and its profitability test, and said exceptions should not be granted based on market value alone.
Does the exchange affect the share price?
Business Insider said the decision “likely matters little” for how Anthropic trades, and there is no definitive evidence that companies perform better on one exchange than the other.
