Best AI on Dec 31, 2026? — Claude priced at 44.9% on Kalshi, down 14.9 points, on $3.2M traded

Claude’s Kalshi contract on whether it will be the best AI on Dec 31, 2026 was priced at 44.9%, down 14.9 percentage points over 24 hours, according to PredictionBubbles. The contract had recorded $3.2M in traded volume.

The figures come from PredictionBubbles’ Oct. 29, 08:26 UTC crawl. Its technology board tracked 67 open markets with $67.5M traded, placing the Claude contract within a broader set of bets on AI milestones, product launches, valuations and company events.

A sharp move, but no stated catalyst

The decline represents a substantial shift in the market-implied probability of Claude meeting the year-end condition. However, the supplied material does not identify a news event behind the move or provide the contract’s criteria for deciding which AI is “best.”

PredictionBubbles distinguishes between its rankings for price changes and trading activity: movers are ranked by absolute probability changes over the previous 24 hours, while volume rankings reflect total trading. The Claude contract’s $3.2M therefore measures cumulative activity, not necessarily the money traded during its latest decline.

A cross-venue snapshot

According to PredictionBubbles, the board covers 13 Kalshi markets and 54 Polymarket markets, with data refreshed every 15 minutes. The venues trade continuously, so the displayed figures are a periodic snapshot rather than a guarantee of the current price.

The board’s most-traded technology contract at the last refresh concerned whether the U.S. would confirm that aliens exist before 2027, with $29.7M traded on Kalshi. PredictionBubbles aggregates venue prices rather than accepting wagers, holding funds or offering trading accounts.

What it means for prediction markets

• Probability is not a performance verdict: The 44.9% price reflects the market’s assessment of the Claude contract, not an independently established ranking of AI systems.
• The move and the volume answer different questions: The 14.9-point drop captures a 24-hour repricing; $3.2M is total traded volume.
• Resolution language matters: The supplied material does not explain how “best AI” will be determined. PredictionBubbles also cautions that related questions across Kalshi and Polymarket can differ in wording and resolution rules.
