UFC Fight Night: Wellington Turman vs. Islam Dulatov (Welterweight, Main Card)

Platform comparison

Market context

Wellington Turman faces Islam Dulatov in a welterweight bout on the main card of UFC Fight Night: Ankalaev vs. Rountree Jr. on 25 July 2026. The current crowd-implied probability of 49% for Turman suggests near-parity in market assessment, though liquidity distribution across platforms reveals meaningful divergence. Polymarket's decimal-odds display (approximately 2.04 for Turman) and Kalshi's binary YES/NO structure both reflect this tight pricing, yet Kalshi's US-only KYC framework and Polymarket's broader international reach mean different trader cohorts are pricing the same event. Betfair and Smarkets, meanwhile, show marginally tighter spreads on comparable welterweight matchups, suggesting their commission structures (0.5–2% versus Polymarket's 2% and Kalshi's flat fee) attract sharper action on UFC main-card fights.

Turman, a Brazilian welterweight with a record of 12 wins and 4 losses, has competed consistently in the UFC since 2021, though recent form has been mixed. Dulatov, a Kyrgyz fighter with 13 wins and 1 loss, represents a less-documented opponent in Western betting markets, which typically inflates uncertainty and widens spreads. The resolution window closes 26 July 2026 at 03:59:59 UTC, allowing for same-day settlement once official UFC scorecards are published. Traders should monitor official UFC weigh-in confirmations and any last-minute fighter withdrawals; the 50-50 resolution clause for cancellations or postponements beyond 8 August 2026 creates tail-risk exposure if scheduling disruptions occur. Recent UFC Fight Night events have settled within 24 hours of conclusion, providing reliable liquidity windows for position exits.
