Stirling (10-0) prices at 74c on both Kalshi and Polymarket, with Blachowicz (29-11-2) at 27c, and the two books agree to the cent. Roughly $87K in volume sits across the fight, the bulk of Kalshi's action stacked on the Blachowicz underdog side. The live board above carries the current cross-platform prices and the Polymarket method and round props.
Navajo Stirling is the 74c favorite over former UFC light heavyweight champion Jan Blachowicz, and the market is doing something it rarely does to a titleholder: fading him against a fighter with fewer than half his professional bouts. Stirling (10-0) trades at 74c on both Kalshi and Polymarket; Blachowicz (29-11-2) sits at 27c. The bout is the light heavyweight co-main event of UFC Fight Night in Belgrade on August 1, 2026, the promotion's first card in Serbia. Stirling stepped in on short notice after original opponent Bogdan Guskov withdrew.
Blachowicz vs Stirling Moneyline Read
The 74c line prices Stirling at roughly a 74% implied chance to win, and the two books do not disagree: Kalshi and Polymarket both list Stirling at 74c and Blachowicz at 27c, so there is no cross-platform edge on the moneyline and no arbitrage to work. The story is age and trajectory. Blachowicz is 43 and winless in his last two, a decision loss to Carlos Ulberg in March 2025 and a majority draw with Guskov at UFC 323 in December 2025, and a torn meniscus scratched him from an earlier version of this rematch. Stirling is a 28-year-old New Zealander out of City Kickboxing who is unbeaten as a pro and has won five straight in the UFC, including stoppages of Ion Cutelaba and Bruno Lopes. He entered the week ranked inside the divisional top ten.
One wrinkle sits under the consensus: Kalshi's volume is stacked on the underdog. The Blachowicz contract holds roughly $22.6K of Kalshi volume against about $4.8K on Stirling, contrarian money on the former champion that has not pulled the price off 74c. Total volume across the fight is near $87K. The intraday tape shows no divergence between the two books, both holding Stirling at 74c, so the market has not repriced the short-notice angle.
Blachowicz vs Stirling Method and Rounds Markets
The secondary markets live on Polymarket and carry thin volume, so treat them as directional rather than settled. Polymarket prices the fight to go the distance at 61c, and a KO or TKO finish by either fighter at 53c, with Stirling by KO or TKO specifically at 49c. That is a near coin flip on a finish even though Stirling has stopped six of his ten pro wins. On the round totals, Polymarket has the fight over 2.5 rounds at 65c and over 1.5 rounds at 79c, consistent with a bout expected to reach the later rounds of a three-round co-main. These props sit at or near zero traded volume, so the moneyline is the only line with real liquidity behind it.
