Anthropic's valuation hit (HIGH) $3.0T by December 31 priced at 20.5% on Polymarket, up 3.0 points, on $1.6M traded

Anthropic’s contract on reaching a $3.0T valuation by December 31 was priced at 20.5% on Polymarket, up 3.0 percentage points over 24 hours, with $1.6M traded, according to PredictionBubbles’ finance-board snapshot dated Oct. 28, 2026, at 10:10 UTC.

The price indicates that the valuation outcome remained less likely than not in market terms, despite the upward move. The supplied material does not identify a company announcement or other catalyst behind the repricing.

A valuation bet on a broader finance board

According to PredictionBubbles, its finance page tracked 213 open markets at the latest refresh: 193 from Polymarket and 20 from Kalshi. The board covers questions including interest-rate decisions, inflation, recession outcomes, and index and commodity levels.

The Anthropic contract’s $1.6M in traded volume was below the board’s most-traded finance market. That contract, asking whether Fed interest rates would remain unchanged after the October 2026 meeting, had $28.5M traded on Polymarket, according to PredictionBubbles.

Reading the snapshot

PredictionBubbles refreshes its data every 15 minutes, while trading on the underlying venues continues between updates. Its probability-change measure covers the previous 24 hours; the volume figure represents total traded volume, not money traded during that same daily window.

The supplied material does not include the Anthropic contract’s detailed resolution rules. It therefore leaves unspecified what evidence would establish that the $3.0T valuation threshold had been reached by December 31.

What it means for prediction markets

• Higher odds, still a minority outcome: The 3.0-point increase brought the market-implied probability to 20.5%, rather than making the valuation threshold the expected result.
• Volume and momentum measure different things: The $1.6M total reflects accumulated trading, while the probability move captures only the latest 24 hours.
• Resolution details remain important: Without the full contract rules, the snapshot alone cannot establish which valuation evidence would qualify.
• The price is time-specific: The 15-minute publication cycle means subsequent trades may not be reflected in the cited reading.
