Market context
Alice Ardelean is scheduled to face Polyana Viana at women’s strawweight on the UFC Fight Night prelims in Las Vegas. The current 100% YES price should be read as a settlement artefact rather than a clean signal on fight quality: the contract is already tied to a specific winner, with the alternative outcome being a 50-50 resolution only if the bout is a draw, no contest, cancelled, or pushed past 30 May. In that sense, the market is mainly about event completion and official result risk, not just who is likelier to win.
Comparable UFC prop and winner markets tend to tighten sharply when both athletes are already on the card and the weigh-in window has passed, because the main remaining risks are late injury withdrawals, commission issues, or a changed bout order. Recent preview coverage has framed Ardelean as a volume-based striker and Viana as the more submission-dangerous fighter, which is relevant because this kind of stylistic pairing can produce late finishes or messy scorecards, but it still resolves only on the official UFC result. For accessibility, a “no-KYC up to $1,500” framework typically means smaller positions can be opened without full identity checks, while larger activity or withdrawals may trigger verification; German users also need to factor in GlüStV restrictions on regulated gambling-style products, and US-facing access sits within CFTC jurisdictional limits and platform-specific rules.
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
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.
- What does it cost to trade on PolyGram?
- Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
