Market context
Fiorentina host Atalanta in Serie A on 24 May, and Polymarket’s “More Markets” contract is pricing a 9% yes probability today, with traders posting USDC against conditional tokens on Polygon. At that level, the market is treating the listed outcome as a low-frequency add-on rather than a central match script, so the relevant question is whether the game develops into the specific state named in the contract, not simply who wins. The settlement window runs to 2026-05-24T13:00:00Z, so any late team news or schedule change before then can still matter.
Recent comparable pricing on the 1X2 market has been noticeably tighter: Robinhood’s live prices showed Atalanta around 40¢, Fiorentina 35¢ and the draw 28¢, while outside previews have leaned towards a narrow, medium-scoring contest. That combination usually leaves “more markets” outcomes anchored to game state rather than outright result, with low yes prices reflecting how often a specific side condition actually lands across similar Serie A fixtures. Earlier previews also noted an even head-to-head over the last six meetings, which is relevant because balanced match-ups tend to compress the probability of niche settlement paths.
The main catalysts are team sheets, any rotation, and the match schedule itself. A delayed kick-off, a change in venue, or a revised start time would be more important here than the headline score forecast, because these contracts resolve from the exact listed conditions. Traders should also watch for late injury updates and whether either side has incentive to manage minutes, especially with the closing days of the Serie A calendar often bringing different priorities for mid-table teams.
Methodology
This page reviews ACF Fiorentina vs. Atalanta BC - More Markets across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
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's the difference between YES and NO shares?
- 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.
- 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 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.
