anthropic ipo raise odds: $65B-$75B Leads at 53% After Retracted Draft

The anthropic ipo raise odds moved fast overnight: on Polymarket's "How much will Anthropic raise in its IPO?" market, the $65B to $75B bracket led at about 52.6% Yes at our gamma pull around 06:01 UTC on November 10. That came after Reuters reported that a filing showing a raise of up to $69.3 billion was briefly sent to banks on Monday and then pulled back as "inaccurate."

What actually happened

Reuters reported late on November 9 that an Anthropic representative emailed banks a copy of a securities filing showing plans to sell about 867 million Class A shares at $70 to $80 per share. A follow-up email said the pricing details were inaccurate and that Anthropic would update the filing later. The second email did not say what was wrong, and Reuters could not determine it. Anthropic declined to comment.

According to the retracted draft, Anthropic itself would sell about 843.3 million shares and existing shareholders about 23.3 million. The same draft showed a separate $26 billion private placement of Class N stock at the IPO price from Alphabet's Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC, set to close right after the IPO.

The official record still has no price range. FinanceFeeds noted that the latest amended S-1 on SEC EDGAR, dated November 2, leaves the price and share-count fields blank. We covered the original filing in anthropic s-1 filing.

What Polymarket thinks

The market resolves on total gross proceeds at the final offering price, as shown in the final prospectus. Two rules matter a lot here: shares from any greenshoe overallotment do not count, and shares sold in a private placement alongside the IPO do not count either. So the reported $26 billion strategic placement would not be added to the total.

Here are the anthropic ipo raise odds from our pull at about 06:01 UTC on November 10:

• Under $65B: 13.8% Yes
• $65B to $75B: 52.6% Yes
• $75B to $85B: 22.0% Yes
• $85B to $95B: 5.1% Yes
• $95B to $105B: 4.4% Yes
• $105B to $115B: 4.5% Yes

The leading bracket has a very wide order book. At our pull the best bid was about 36 cents and the best ask about 69 cents, with a last trade near 71 cents, so the 52.6% figure is a midpoint, not a firm price. The whole event had about $194K of volume, and the $65B to $75B line only about $9K. A single trader can move it.

Why the draft was pulled matters

There are several possible reasons a company would recall pricing details a few hours after sending them: the share count could change, the range could move, or the split between new and existing shares could be adjusted. Reuters did not learn which one applied here. Each of those changes would shift the gross proceeds, which is exactly what this market settles on, so the recall itself is a reason to treat today's prices with extra caution.

How the numbers fit together

The retracted draft points straight into the leading bracket: 866.7 million shares at $80 gives $69.3 billion, and at $70 it gives roughly $60.7 billion, which would fall under $65 billion. That is why traders split their bets between the two lowest brackets. If the final share count or price changes, the math changes with it.

Earlier reports pointed higher. Dealroom, summarizing a Financial Times report from November 6, said Anthropic expected to raise $80 billion to $100 billion at a valuation of $1.25 trillion to $1.75 trillion. Reuters now says the $1.5 trillion figure is viewed as the high end. We track the valuation side in anthropic ipo market cap odds and timing in anthropic ipo date odds.

What to do as a reader

Read the anthropic ipo raise odds as a snapshot of how traders interpret one retracted email, not as a forecast. Check the live Polymarket market before relying on any figure, and watch SEC EDGAR for the next S-1/A, which should carry the real price range and share count.

Remember the resolution rules on greenshoe and private placements, and expect the book to swing when the official range lands. Nothing here is investment advice.
