Is the In-Season Tournament Actually Bettable Yet?
The NBA Cup, formerly the NBA In-Season Tournament, completed its third edition in December 2025, and the event's betting legitimacy has evolved considerably from its skeptical reception in Year 1. The 2025 edition produced one of the great upset storylines of the entire NBA season: the San Antonio Spurs eliminated the Oklahoma City Thunder, who opened as -429 favorites in the semifinal, before falling to the New York Knicks as underdogs in the final. That single result encapsulates everything interesting about the NBA Cup from a betting perspective: enormous chalk vulnerability, massive payout potential, and a field broad enough that any given night can produce an institution-shaking upset.
