Polymarket traders now see a 31.7% chance Anthropic will be the largest IPO of 2026 by market cap. That’s down from around 46% a week ago, with the odds dropping sharply in recent days before recovering slightly. More than $7.4 million has been traded on the market.
Context
Falling prediction market odds on Anthropic's IPO size show traders marking down the lab after a week of AI market stress.

Deep dive
unusual_whales (@unusual_whales) posted on Nov 4 that Polymarket traders now see a 31.7% chance Anthropic will be the largest IPO of 2026 by market cap.
According to the post, that is down from around 46% a week earlier, with the odds dropping sharply in recent days before recovering slightly, and more than $7.4 million traded on the market. The chart shows the one week path with a steep drop around Nov 3.
Prediction market prices are not company guidance. They can move on news, jokes and thin liquidity.
The print updates the Anthropic IPO odds thread that began in the Nov 3 deck. It does not say Anthropic cancelled an IPO. It only shows traders assigning a lower chance that Anthropic leads 2026 by market cap.
Taken with the public tech selloff the next day, the print fits a wider markdown of AI lab optimism rather than a single rumor about a cancelled listing.

What to expect next
Watch the same Polymarket market after more AI stock moves and any Anthropic funding or IPO comments. Comparing this 31.7% print with other venues will show whether the move is broad. A rebound in AI public equities could lift the odds again without any company news. Filings or banker rumors about a 2026 listing would matter more than any single Polymarket print.
