Market context

Alice Ardelean is scheduled to face Polyana Viana in a women’s strawweight bout on the UFC prelims at UFC Fight Night: Allen vs. Costa. For a trader running this through bots or conditional orders, the key live input is not the headline market price but whether the fight actually reaches the official result feed: if it is started and then stopped by retirement, disqualification, or a late no contest, the settlement can still diverge sharply from a simple win/lose assumption.

The 100% yes price is more a reflection of market structure than sporting certainty. These UFC fighter-vs-fighter markets can pin at one side when liquidity is thin, especially near event time, and that does not eliminate the practical risk of a settlement reset if the bout is delayed, changed, or cancelled. A useful comparator is Ardelean’s recent win over Viana, highlighted in post-fight clips after UFC Vegas 117, which suggests the market is likely being read through recent form rather than a broad rating model. In programmatic terms, the implied probability should be treated as a signalling artefact only if the bet can still be invalidated by schedule or officiating outcomes.

The main catalysts are administrative rather than tactical: official weigh-in status, any late-card reshuffle, and whether UFC confirms the bout from the Apex on the final run-up to the prelims. Kalshi’s market rules note that postponements within the allowed window can keep the market open, while a cancellation or reschedule beyond two weeks forces fair-value resolution, so automated strategies should monitor the UFC’s official bout sheet and result feed rather than rely on previews alone.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
