Market context
Inter Milan travel to Bologna on 24 May for a Serie A fixture with significant implications for both clubs' European qualification prospects. The match falls in the final weeks of the domestic season, when fixture congestion and squad rotation patterns become decisive factors. Bologna, currently mid-table, have shown inconsistent form through the campaign, whilst Inter remain genuine title contenders with Champions League commitments potentially affecting their squad availability.
Historically, Inter's superior depth and experience in high-stakes finishes has favoured them in May encounters. Over the past five seasons, Inter have won three of their last four meetings with Bologna, though the Rossoblu secured a 1–1 draw at the San Siro in February 2024. The 56% probability assigned to "more markets" suggests traders are pricing in competitive uncertainty—likely reflecting Bologna's home advantage and Inter's potential rotation given their continental obligations. Inter's injury list and suspension status heading into late May will be critical; any absence of key midfielders or forwards materially shifts the expected goal differential.
Watch for team news releases from both clubs in the week preceding the match, particularly Inter's squad decisions following any European commitments concluded just before this fixture. Bologna's recent form against top-six sides offers a useful indicator of their capacity to trouble Inter's defence. Confirmation of starting line-ups approximately 90 minutes before kick-off will be the final catalyst affecting the market, as will any late-breaking injury announcements that typically emerge on match day morning.
Methodology
We track Bologna FC 1909 vs. FC Internazionale Milano - 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.
