Anthropic $2.5T valuation by Dec 31 falls to 24% on Polymarket
Down 12 points on $468K traded, among the day's biggest downward moves.
The Polymarket contract on Anthropic reaching a $2.5T valuation by December 31 fell 12 probability points to 24%, with $468K traded, according to PredictionBubbles. The tracker placed the contract among the day’s largest downward moves.
A threshold-specific repricing
The move concerns the $2.5T valuation threshold specifically. It is separate from the $1.5T and $3.0T Anthropic valuation contracts referenced in the supplied summary; the material does not provide updated probabilities for those markets.
The decline measures a change over 24 hours in probability points, not a relative percentage drop. It reflects a lower market-implied likelihood of the $2.5T outcome, rather than a reported change in Anthropic’s actual valuation. The supplied reporting identifies no company announcement or other catalyst for the move.
How the ranking works
According to PredictionBubbles, the snapshot used prices collected from the venues on 16 Oct 2026, 20:12 UTC. Its rankings refresh every 15 minutes and cover Polymarket and Kalshi, ordering contracts by the size of their 24-hour probability-point changes.
The ranking universe comprised 1,985 markets lasting longer than 14 days, excluding short-lived fixtures that can move sharply as they approach settlement. Trading volume and liquidity provide context but do not influence the ranking. The $468K traded figure therefore accompanies the Anthropic repricing; it does not determine its position among the movers.
What it means for prediction markets
- Keep the thresholds separate: The 24% reading applies to the $2.5T contract, not the $1.5T or $3.0T alternatives.
- Distinguish pricing from company value: The 12-point decline records a shift in traders’ assessment, not evidence that Anthropic’s valuation itself fell.
- Treat volume as context: The reported $468K traded does not establish market depth or explain what drove the move.
- Use the timestamp: These figures describe the supplied snapshot, not necessarily subsequent prices.
