1. FC Cologne vs. Real Sociedad San Sebastian - More Markets

Platform comparison

Market context

1. FC Köln against Real Sociedad is a club friendly whose market has now hardened into an overwhelmingly likely “yes” for additional markets, with the crowd at 96% as kickoff and settlement approach. That price has moved in a very short window around the fixture, but the underlying game state remains the same: a pre-season exhibition between Bundesliga and La Liga opposition, with little margin for traders to infer much beyond line-up intent and rotation risk.[1][2]

The historical read is that friendlies between major European clubs often produce messy probabilities because managers use them to test combinations rather than chase results. External previews on this match point in different directions on the exact scoreline, but they agree on the broad shape: a competitive, low-conviction contest where a draw or one-goal result is plausible and the usual in-season expectations are softened by substitutions and uneven minutes.[3][5][15] That makes a 96% crowd consensus more a reflection of market structure than certainty about the football itself.[1][6]

The main catalysts to watch are team news, late squad travel notes, and confirmation of who actually starts, because one confirmed Sociedad absence has already been flagged and further rotation would matter more than most pre-match numbers.[1] The market also needs to absorb any official club announcements on final friendly scheduling, venue timing, and whether either side treats this as a first-choice rehearsal or a heavy turnover session, since that will determine how much signal the pre-match price really contains.[1][14]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.

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.

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction.
