Anthropic's valuation hit (HIGH) $2.5T by December 31 priced at 37.0% on Polymarket, up 5.5 points, on $517K traded

Anthropic contract moves higher

Polymarket’s contract on whether Anthropic’s valuation will reach $2.5T by December 31 was priced at 37.0%, up 5.5 percentage points, with $517K traded, in the supplied market update published Oct 29, 2026, at 4:54 PM ET.

The move represents a higher market-implied probability of the valuation threshold being reached, not evidence that Anthropic has achieved that valuation. Despite the increase, the contract remained below 50%.

No fresh catalyst identified

The accompanying news summary identified no significant new platform headline in the preceding 30 minutes. It described search results as recirculating previously reviewed material, leaving the supplied reporting without a verified fresh catalyst for the repricing.

According to predictionbubbles.net, its movers board measures changes over 24 hours in probability points and refreshes every 15 minutes using prices from Polymarket and Kalshi. The supplied page lists a venue-data timestamp of 29 Oct 2026, 21:16 UTC, but its excerpt does not include an Anthropic-specific entry independently confirming the headline figures.

The outlet also distinguishes trading volume from price movement: activity and repricing measure different things. The reported $517K provides context, but the supplied material does not establish the contract’s order-book depth or explain what drove the increase.

What it means for prediction markets

• The change is in percentage points: The 5.5-point rise describes a shift in implied probability, not a 5.5% relative increase.
• The catalyst remains unverified: The available news summary does not connect the move to a new Anthropic announcement.
• Volume does not establish liquidity: The $517K traded figure alone cannot show how readily sizable orders could move the price.
• Settlement details are missing: The supplied material does not specify which valuation evidence would qualify for resolving the $2.5T contract.
