Market context

Theodor Berggren, the Swedish debutant, faces Ukraine’s Daniil Donchenko in a welterweight prelims scrap at UFC Fight Night in Baku on 27 June 2026. Donchenko, a 13-2 veteran with a brutal first-round TKO record, is heavily favoured by bookmakers and analysts, with odds of -500 against Berggren’s +380[1][2]. The crowd-implied probability of Berggren winning sits at 0% YES, reflecting near-universal confidence in Donchenko’s superiority and finishing ability.

Historically, debutants stepping in on short notice against experienced welterweights with TKO pedigrees rarely overcome such odds unless they possess elite grappling or unorthodox striking. Donchenko’s average fight time of 9:44 and 14-2 record suggest consistent early dominance[6]. Comparable cases from recent UFC Baku events show that short-notice debuts against veterans with similar records typically resolve in favour of the established fighter, especially when the veteran has a clear TKO path[1].

Traders should monitor official UFC fight results, post-fight medical reports, and any potential no-contest rulings that could trigger the 50-50 resolution clause[4]. The fight is scheduled to conclude before 2:40 pm local time, with Donchenko predicted to win by TKO[2]. Any delay beyond 11 July 2026 would alter the market’s settlement, but current schedules indicate no postponement is expected[5]. The resolution source remains official UFC data, ensuring on-chain conditional tokens on Polygon settle accurately in USDC.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
