Market context
Fiorentina host Atalanta in Serie A on Sunday, with the market looking for whether there will be at least one further “more” outcome in the game. The baseline for a 9% yes price is that these bets are usually narrow, event-specific outcomes rather than a broad view on the result itself, so recent scorelines and team shape matter more than reputation. Fiorentina’s season has been uneven — FotMob has them 15th and Atalanta 7th — but the head-to-head has often been open enough to produce chances, with AiScore listing five-match goal rates of 80% for both sides and seven of the last ten meetings involving both teams on the scoresheet.
The immediate variables are team news and any late rotation. FotMob’s predicted line-ups show Fiorentina without Moise Kean, Luca Ranieri and Fabiano Parisi, while Atalanta are missing Odilon Kossounou and Lorenzo Bernasconi. Fiorentina’s shape also points to a 4-1-4-1 built around David de Gea and Roberto Piccoli, while Atalanta’s 3-4-1-2 keeps Charles De Ketelaere, Raspadori and Krstovic close to goal. OddsChecker noted both sides still have something to play for in the table, which can limit the incentive for caution and keep second-half substitutions and late tactical changes relevant to “more” markets. Final team sheets and any confirmation of whether either side rests players ahead of the run-in are the key dependencies before settlement.
Methodology
We track ACF Fiorentina vs. Atalanta BC - More Markets on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
- 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.
