Who will win the 2026 Fields Medal?

Platform comparison

Market context

The 2026 Fields Medal is now being decided at the International Congress of Mathematicians, with the winners announced on 23 July and the market resolving from that official list by 15 August if coverage is delayed. Early reporting now names Yu Deng, John Pardon, Jacob Tsimerman and Hong Wang as the four medalists, which means a 0% crowd price only made sense before the announcement and should be treated as stale rather than informative.[1][2][3][4]

For historical framing, the Fields Medal is awarded every four years to between two and four mathematicians under 40, so markets tend to reprice sharply only when the IMU schedule becomes concrete and then collapse to the actual names once the announcement lands. Recent pre-announcement pricing across prediction venues had already clustered around Hong Wang and Jacob Tsimerman as front-runners, with Yu Deng and John Pardon also appearing in the main contender set, which is consistent with how these contracts usually behave: a small number of plausible winners, then a binary jump once the official communiqué is published.[8][10][11][13]

A practical way to handle this market programmatically is to watch the ICM programme, IMU and major wire-service headlines, then trigger orders or alerts on the first official medal notice rather than on speculative lists. The key dependency is timing: if the IMU announcement is issued during the congress window, the contract should resolve immediately to those named; if it is somehow not published by 15 August 2026 23:59 ET, the market goes to “Other”, so any bot or copy-trading rule should have a hard stop before that deadline.[1][2][3]

Methodology

We track Who will win the 2026 Fields Medal? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
