Anthropic have the highest IPO Market Cap 2026 priced at 28.0% on Polymarket

Anthropic’s implied chances rise

Anthropic was priced at a 28.0% probability on Polymarket to have the highest IPO market capitalization in 2026, according to the supplied market snapshot published Oct. 24, 2026, at 3:09 PM ET.

The snapshot showed a gain of 7.4 percentage points and $1.4M in traded volume. The probability was also up 2.7 percentage points since Oct. 20, indicating that the latest price stood above that earlier reading.

What the available data establishes

According to predictionbubbles.net, its finance dashboard reports market-implied probabilities, changes over the preceding 24 hours and total traded volume. Its data refreshes every 15 minutes, rather than reflecting every trade immediately.

The supplied dashboard text does not include an Anthropic-specific entry, contract terms or an explanation for the price movement. The figures therefore document a shift in market pricing, but do not establish what prompted it or how the contract defines and measures IPO market capitalization.

What it means for prediction markets

• Probability, not valuation: The 28.0% price represents the market-implied chance of the specified outcome, not an estimate of Anthropic’s market capitalization.
• Different comparison windows: The snapshot reports a 7.4-point increase alongside a 2.7-point gain since Oct. 20. Those moves should not be treated as interchangeable.
• Volume has limits: The $1.4M figure measures reported trading activity; it does not establish current liquidity or the reliability of the implied probability.
• Resolution details remain missing: Without the contract’s full wording and settlement rules, the precise conditions required for an Anthropic win cannot be assessed from the supplied material.
