⚡ Disputes

NBA Free Agency markets (DeMar DeRozan & Rui Hachimura) — Two Polymarket NBA free agency markets are under dispute while in archived/pending-clarification status. The core issue: both players have joined new teams, but the market structure creates ambiguity about which team is the correct resolution. laurleo notes it "could genuinely go either way" depending on whether title or description string takes precedence. abhiz69 and armanh01 criticized proposing archived markets as inviting adverse selection. Polymarket team apparently didn't extend the dispute window, which abhiz69 called "shocking." alexchunus raised a broader concern — a precedent from a prior "negrisk" market where an early wrong proposal was voted P2 (instead of P4 pending clarification), effectively allowing a misresolve to slip through. nefffooor echoed frustration: "Just let the wrong bracket slip through on negrisk and then you can do whatever you want and UMA will support it." mebeim noted UMA's hands are tied if Polymarket doesn't clarify in time.

ITF tennis set total market — mrchowchowdamn flagged a potential misresolve on an ITF match (Lizuno vs Jansse, Sep 14): Set 1 O/U 9.5 was proposed Under, but the set ended 6-4 (10 games total = Over). laurleo and fernando5495 confirmed it likely misresolved and could have been disputed, with laurleo noting "6-4 is obviously over 9.5."
