NBA Finals odds and 2026 betting favourites: Thunder heavy favourites to repeat, Pistons make up ground in a wide-open East

NBA Finals odds

The Oklahoma City Thunder are heavy favourites to win the NBA Finals after getting off to a 24-1 start.

The latest: Just six months after the Thunder won their first championship in franchise history, they seem poised to repeat. As of Dec. 12, 2025, they’re a +100 favourite to go back-to-back. This hot start shouldn’t come as a surprise. OKC finished last year with an NBA-best 68-14 record.

The Detroit Pistons top a wide-open Eastern Conference, and have gotten stellar play from emerging stars Jalen Duren and Cade Cunningham. Two dark horses — the Toronto Raptors and Miami Heat — are in the mix, while the Cleveland Cavaliers remain the conference favourite despite an underwhelming start.
