UFC Fight Night: Duško Todorovic vs. Robert Valentin (Middleweight, Main Card)

Platform comparison

Market context

Duško Todorović faces Robert Valentin in a scheduled middleweight main-card bout, and the market’s 0% YES price means the crowd is treating a Todorović win as highly improbable despite the fight being on the official UFC card. For a programmatic workflow, that makes the contract a classic event-driven binary: the key inputs are the UFC result feed, bout status flags, and any late card reshuffles before the settlement window closes.

The historical frame is not cleanly supportive of either side, but the published numbers point to a stylistic split. Todorović has the higher striking volume and more takedown attempts, while Valentin’s profile is more submission-heavy and he owns the longer reach, with UFC Stats showing 4.73 significant strikes landed per minute for Todorović against 1.30 for Valentin, and 1.8 submission attempts per 15 minutes for Valentin against 0.3 for Todorović.[5] Comparable preview sites also describe Todorović as the higher-output attacker and Valentin as the more submission-oriented finisher, which matters because a low yes price can persist even when one fighter has clearer volume edges if the market thinks the matchup shape favours the other side or the result path is fragile.[1][7]

The catalysts to watch are mundane but decisive: official weigh-in confirmation, any injury or card change notice, and the UFC’s final result declaration, because a no contest, draw, cancellation, or postponement beyond the market’s cutoff resolves to 50-50 rather than either fighter.[5] For trading tools or conditional orders, the cleanest approach is to key alerts off the UFC bout status and result post, then cancel stale orders once the fight is underway; if the bout is reported as cancelled or moved, the settlement logic changes immediately and can dominate price before the market updates.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Review UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
