UFC Fight Night: Amanda Lemos vs. Alexia Thainara (Women's Strawweight, Prelims)

Platform comparison

Market context

Amanda Lemos’s women’s strawweight bout with Alexia Thainara is a veteran-versus-riser matchup at UFC Fight Night, and the market’s 0% YES implies it is pricing in an outcome that has not been materially reflected in pre-fight opinion. Recent previews have generally made Thainara the clear favourite, with prices around -235 to -265, while Lemos has been offered in the +195 to +215 range, which is consistent with a younger fighter on a long winning run against a former title challenger on a two-fight skid.[2][3][11]

The historical frame is straightforward: Lemos has lost back-to-back unanimous decisions to Tatiana Suarez and Gillian Robertson, while Thainara entered unbeaten in the UFC and on a double-digit overall streak, so the market is effectively weighing durability and experience against momentum and grappling upside.[2][15] Comparable previews also point towards a decision-heavy script, with both fighters often going the distance in recent bouts, which matters for resolution because a close, competitive three-round fight is more likely to produce a scorecard result than an early finish.[6][15]

For traders, the key catalysts are official UFC bout status, weigh-in and cage-walk confirmation, and any late-card changes at APEX that could alter timing or opponent readiness. The most recent reporting placed the fight on the UFC Vegas 120/Fight Night card at Meta APEX in Las Vegas and expected the women’s strawweight contest to be one of the evening’s scheduled prelim or early-card fights, so any medical withdrawal, missed weight, or card reshuffle would be the main route to a 50-50 settlement rather than a routine win call.[2][10][11]

Which sports markets are available?

How fast do sports winnings settle?

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
