The Golden State Warriors' odds to win the 2027 NBA championship have collapsed to roughly 1% on prediction market platform Kalshi, a dramatic reversal from the double-digit odds the franchise briefly commanded earlier this summer, after superstar LeBron James chose to sign with the Philadelphia 76ers rather than join forces with Stephen Curry in the Bay Area. According to Kalshi pricing at the time, the Warriors' odds opened the 2027 futures market at roughly 1.5%, implied by opening odds of +6600, before climbing as high as 3.3%, implied by odds of +3000, by mid-July as the LeBron speculation intensified. A separate Kalshi market specifically tracking the NBA Finals price briefly lifted the Warriors from 2% up to 6%, tying them for fifth on that particular board at the peak of the speculation. Meanwhile, the 76ers' own championship odds moved dramatically in the opposite direction. A Market Still Topped by the Same Familiar ContendersEven with Philadelphia's post-LeBron surge, the top of Kalshi's 2027 championship market has remained largely unchanged at its peak.
