Pat Sabatini and William Gomis are scheduled to compete in a featherweight bout on the early preliminary card of UFC 328, headlined by Khamzat Chimaev versus Sean Strickland on 9 May 2026. The market currently reflects a 60% implied probability for Sabatini's victory, as formed by the order book on Polymarket. This represents a meaningful favourite position, though not overwhelming confidence in the outcome.
Sabatini, a Philadelphia-based featherweight, has competed regularly on the UFC's preliminary circuit with a mixed record of competitive performances. Gomis, a French fighter, brings European fight experience to the matchup. Early preliminary bouts typically feature fighters establishing themselves or rebuilding their records, which can produce less predictable outcomes than main card fights. The 60% probability suggests the market views Sabatini as the more likely victor, though the 40% implied for Gomis indicates meaningful uncertainty about the outcome.
Traders should monitor fighter health and training camp reports in the weeks preceding the event, as injuries or late withdrawals could trigger a No Contest resolution. The UFC's official weigh-in results on 8 May will confirm both fighters made weight. Any schedule changes or postponements beyond 23 May would also resolve the market to 50-50. Settlement depends entirely on the UFC's official decision, which will be published through standard UFC channels following the bout conclusion.
This market settles from the official outcome published at https://www.ufc.com/events. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "UFC 328: Pat Sabatini vs. William Gomis (Featherweight, Early Prelims)" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$102K in lifetime turnover and $94K of resting liquidity puts this market in the top 30% by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $88K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is sourced from https://www.ufc.com/events. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 10 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
