Pronóstico: Who will win the 2026 Fields Medal?

Platform comparison

Market context

Polymarket is pricing this contract at **0% YES**, which on-chain means the market is effectively saying no eligible winner has been confirmed in the conditional token set so far, with positions settled in **USDC on Polygon** once the event resolves. In practical terms, that leaves traders holding a contract that will only pay if the 2026 Fields Medal announcement matches the market’s resolution rules before the **15 August 2026** fallback deadline.

That reading sits awkwardly against the historical pattern for this prize. The Fields Medal is normally announced at the International Congress of Mathematicians, held every four years, and the 2026 congress runs from **23 to 30 July**. In comparable past cycles, prices tend to stay concentrated around a small number of names until the IMU announcement lands, then snap to the actual medalists rather than to broad pre-congress chatter. Recent reporting on 23 July says the 2026 medals have now been awarded to **Yu Deng, John Pardon, Jacob Tsimerman and Hong Wang**, which is the key reference point for how the contract should resolve if Polymarket’s event logic has been updated to reflect the official announcement.[3][5]

A trader watching this market should focus on the IMU’s published announcement timing, the exact list of medalists, and whether any administrative delay pushes the market towards the “Other” fallback after the resolution window. The main dependency is simple: this contract resolves off the official 2026 Fields Medal winners, not off pre-event favourite lists or media speculation. If the announcement is already public and accepted by the market, the remaining move is likely just resolution mechanics rather than price discovery.[1][3]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
