Analysis

The 2026 Fields Medal will be awarded in July 2026 to a mathematician under 40 for outstanding mathematical achievement. Hong Wang currently has the highest implied probability at 81%, suggesting strong consensus among traders that he is the frontrunner, though John Pardon (41¢) and Jacob Tsimerman (63¢) represent meaningful alternative outcomes. Prices shift as new mathematical publications emerge, conference presentations occur, and the Fields Medal Committee's evaluation process advances toward the July award ceremony. The resolution date is fixed: the International Congress of Mathematicians in 2026, when the Medal Committee will announce the winners. Until then, prices may adjust based on new research announcements, peer recognition, or changes in how traders weight recent accomplishments against career trajectory.

  • Hong Wang trades at 82¢ versus John Pardon at 41¢, indicating a significant but not overwhelming market consensus; the largest single-contract volume ($22 in 24h) is on Pardon, suggesting live disagreement
  • The next Fields Medal announcement is scheduled for July 2026 at the International Congress of Mathematicians; no earlier public decision or preliminary shortlist is expected
  • Recent high-impact mathematics publications, conference talks, or collaborative breakthroughs could shift prices for any of the top five candidates
  • Jacob Tsimerman at 63¢ and Yu Deng at 38¢ remain in contention; combined they represent meaningful non-Hong Wang probability
  • The 10-contract structure means each trader outcome is bound; prices reflect expected probability conditional on that person winning, not joint probabilities across candidates

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.
