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

Platform comparison

Market context

1. FC Köln face Real Sociedad in a club friendly, and the market is effectively pricing the game as a near-foregone conclusion on the *more markets* contract. The crowd-implied probability is 98% YES, which is far more extreme than the wider match market: Polymarket’s match-odds page shows Real Sociedad only as a narrow trader favourite, while Robinhood’s event page is heavily skewed towards Köln in its 90-minute winner market[1][2]. That divergence suggests the contract is not behaving like a normal full-time result market and may instead reflect a specific ancillary condition that traders have already treated as almost certain.

Comparable pre-match models point in a much tighter direction than the 98% figure. One forecast model puts Real Sociedad’s 90-minute win chance at 43%, with Köln at 30% and the draw at 27%, while another set of pre-match probabilities makes Sociedad only a modest favourite at 47%[3][5]. Even a lower-confidence tipster consensus still frames the match as competitive, with one outlet leaning to a 2-2 draw and others expecting goals rather than a one-sided outcome[11][12]. Against that backdrop, a 98% YES price looks disconnected from ordinary 1X2 expectations and should be read through the lens of contract structure, not just team strength.

For traders, the main catalysts are team-sheet and scheduling news rather than long-run form. Polymarket notes pre-season rotation, experimental line-ups and limited reliability of standard form indicators, while also flagging one Sociedad defensive absence that may matter only marginally in a friendly setting[1]. In practice, confirmation of starters, late injury withdrawals, and any change to the fixture or kick-off conditions are the variables most likely to move a side-market like this, especially when the settlement window runs almost immediately after the scheduled August 7 kick-off and any unresolved ambiguity around the underlying “more markets” rule would matter more than the scoreline itself[1][2].

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
