UFC Fight Night: Jan Blachowicz vs. Navajo Stirling (Light Heavyweight, Main Card)

Platform comparison

Market context

Jan Blachowicz vs Navajo Stirling is live on the UFC card, and the market’s **24% YES** implies the crowd sees Blachowicz as an underdog despite his championship pedigree. That gap is easy to understand from the pre-fight numbers: Stirling arrives unbeaten and, on recent comparison pages, is landing significantly more strikes per minute, while Blachowicz’s output is lower but backed by far deeper UFC experience and stronger takedown defence. [9][13][14]

The historical read is mixed. Blachowicz has 29 wins and a long UFC résumé, including title-level opposition, but recent reporting notes he has not won since May 2022 and has gone through two losses and two draws in that stretch. Stirling, by contrast, is 10-0 overall and 5-0 in the UFC, a profile that naturally supports a lower implied price on the veteran while still leaving room for a competitiveness premium if the bout reaches the judges. [2][14][17]

For traders, the main catalysts are final UFC bout-order confirmation, any late card reshuffle, and official weigh-in or medical updates, because the market only resolves on an official UFC result and would flip to 50-50 if the fight is not scored, ends in a no contest, or is postponed beyond the market deadline. Pre-fight previews this week have continued to frame Stirling as the cleaner volume striker and Blachowicz as the more proven operator in longer, tactical fights, so any late signal on pace, injury, or weight-cut condition matters more than the headline record alone. [1][8][13][14]

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.
