On both Polymarket and Kalshi, the head-to-head market resolved to whichever player advanced, with specific rules for retirements, walkovers, and cancellations. Kalshi drove the bulk of activity, recording roughly $1.02M in volume against about $24K on Polymarket. Pricing across the two venues left virtually no doubt about the favourite. Kristina Kroitor sat at a consensus 99.0%, quoted at 99.0% on Kalshi and 99.9% on Polymarket, while Sera Nishimoto was pinned at 1.0% consensus (1.0% on Kalshi, 0.1% on Polymarket). That is roughly a 98-point gap between the two players, signalling that traders treated Kroitor as an overwhelming favourite to advance.
