Market context
Arsenal’s friendly against Real Betis Seville has the market trading at **0% YES** on the “more markets” contract, which is far below the direction implied by pre-match pricing elsewhere. On Robinhood, Arsenal were quoted at **61¢**, with the draw at **28¢** and Betis at **19¢**, while UK and European bookmakers clustered around Arsenal as a clear favourite, generally near **1.57-1.73** for the home side and roughly **3.75-5.25** for Betis.[3][4][8][9][11] That gap suggests the Polymarket contract is not tracking the same event slice as the main 1X2 books, so traders should be careful to compare the exact settlement wording rather than assume “more markets” moves with the match winner.[1]
Comparable previews are still broadly Arsenal-favoured, but not overwhelmingly so in a way that would justify a zero price for a binary contract tied to a specific “more markets” outcome. Recent analyst reads mostly land in the 2-0, 2-1 or 3-1 range for Arsenal, with one model putting Arsenal at **54%** and another at **49%** for a home win, alongside moderate totals and some expectation of both teams scoring.[2][5][7][10][13][17] In that context, the crowd price looks detached from consensus rather than merely cautious, especially given that friendly matches tend to be more volatile because of substitutions and experimental line-ups.[8][10]
For catalysts, the key variables are late team news, confirmed starting XIs, and any change to the match schedule or venue; Polymarket states the market stays open if the game is postponed until completion, so timing risk matters.[1] BBC-style preview coverage and betting previews highlighted Arsenal using the fixture for match sharpness, with names such as Max Dowman, Myles Lewis-Skelly and Christos Tzolis mentioned as players to watch, which means any last-minute rotation could move both goal-based and result-based side markets.[8][13] Because the contract is labelled “more markets”, the precise settlement language is the main dependency, not just the scoreline itself.[1]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
