Analysis

This market is pricing a 17% probability that OpenAI will be recognized as having the #1 AI model by June 30, 2026. However, market data shows significant disagreement: Anthropic's contract for best AI model trades at 68 cents, while OpenAI's identical contract trades at just 6 cents, suggesting the question definition or timeline may be creating divergent valuations. The key driver of current pricing appears to be recent model releases and benchmark performance—traders are weighing whether OpenAI, Anthropic, Google, or other competitors will achieve clear technical leadership in the next 8 weeks. Major model announcements, benchmark results, and real-world performance metrics in enterprise or research contexts would likely shift these probabilities significantly. The resolution will depend critically on how "#1 AI model" is defined and measured at month-end.

  • Massive discrepancy between Anthropic's 68¢ price and OpenAI's 6¢ for ostensibly the same question suggests contract terms, timeframes, or success criteria differ materially between markets
  • OpenAI has been incrementally releasing model improvements rather than major breakthroughs recently, while Anthropic has emphasized constitutional AI development
  • Google commands 23¢ pricing, indicating meaningful probability three-way competition exists among the top three AI labs
  • Current 17% price reflects OpenAI as statistical favorite but far from consensus—runner-up sits at 16%, indicating high uncertainty and fragmented market expectations
  • Resolution depends on how "#1 model" is operationalized (benchmark leaderboards, enterprise adoption, research community consensus, or subjective expert panels)—definitional clarity would likely trigger repricing

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (9% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
