3¢ cheaper on PolymarketResolves Jun 30, 2027

A price is what a $1 contract costs on that venue, so 62¢ means a 62% chance. The line above the prices says what they are for: a match’s favourite, a single question’s Yes, or which outcome of a board both venues price. 24h volume is both venues’ total where both price the event and it is the larger figure, the venue’s own otherwise. Biggest difference ranks the pairs both venues traded at least $1,000 of in 24 hours first; a very large gap can mean the two markets settle on slightly different terms, so check both before you trade. Games under way are left out, so a page can list fewer than 24.
