Which Texas NBA contracts can appear?
Listings change by platform and date. Basketball markets commonly include:
- Single games: who wins, and on some platforms the margin or the total points.
- Season win totals: "Will the Spurs win more than N games?"
- NBA Cup, Western Conference and 2027 championship contracts.
- Awards such as MVP, on some platforms.
Each contract pays $1 if it is right and $0 if not, so its price, between $0 and $1, reads as an implied probability. We don't show prices here because they change constantly; check the exact contract, its close time and its settlement source in the app.
What moves a season-long contract?
One game is one of 82, so opening night moves a championship contract far less than a single result moves an NFL futures price. Injuries, trades and the playoff race matter more over a season. Player-based contracts, such as awards, also depend on how their rules treat missed games, so read those terms closely.
For single games, the details of one night count: home or road, a second game in two nights, a neutral-feeling venue such as the Spurs' Austin game. None of this says which way a price should move; it says what traders weigh.
