The San Antonio Spurs handed the previously unbeaten Oklahoma City Thunder their first loss of the 2026 postseason in Game 1 of the Western Conference finals, but betting markets still list Oklahoma City as the favorite to win the title.
Before Game 1, the Thunder were priced at minus-165 on DraftKings and minus-160 on BetMGM; after San Antonio's shock, Oklahoma City remained the favorite at plus-120. The Spurs responded to their victory with a sharp jump in futures — improving from roughly plus-310 to plus-155 — a swing that underlines how one game has scrambled the title market even as the Thunder keep the short end of the odds.
Only four teams remain in the 2026 NBA playoffs: the Thunder and Spurs in the West, and the New York Knicks and Cleveland Cavaliers in the East. The Knicks and Cavaliers are the conference finalists in the East, with New York listed at plus-550 on both DraftKings and BetMGM and Cleveland at plus-2000 on DraftKings and plus-2200 on BetMGM. On the path to the East finals the Knicks opened last June with identical plus-700 title odds as the Cavaliers, and New York entered the series as minus-275 favorites to advance on BetMGM over Cleveland.
The market movements matter because they reflect a deeper split between form and matchup history. Oklahoma City had swept both Phoenix and the Lakers to reach the West finals at an 8-0 postseason record before Monday night, a run that reinforced perceptions of the Thunder as repeat contenders. Yet San Antonio arrived with better head-to-head cover: the Spurs went 4-1 against Oklahoma City in the regular season and beat the Thunder in the semifinals of the NBA Cup. That past success helps explain why San Antonio's odds shortened so abruptly after Game 1.
History in the markets is stark: the Thunder and Spurs have been the top two favorites to win the NBA Finals since the middle of March, but San Antonio's trajectory has been the more dramatic. The Spurs were as long as plus-4500 in December before climbing into the title race, a rise that now seems validated by their Game 1 performance. Oklahoma City's standing as the market favorite, however, has not evaporated — which is why the bracket still tilts toward the Thunder even after their first defeat.
In the East, the pairing reads like the preseason rematch the market expected. The Knicks opened last June at plus-700 alongside the Cavaliers; Cleveland's odds slipped in March when the Boston Celtics unexpectedly re-emerged as a contender after Jayson Tatum returned from injury. That shift in March is one reason Cleveland's futures moved away from its early-season position. The Cavaliers reinforced their credentials by eliminating the top-seeded Detroit Pistons in the second round en route to the conference finals.
The tension across these threads is simple and immediate: Oklahoma City's postseason form — an 8-0 start, dominant series wins and heavy early-market favoritism — runs up against San Antonio's specific advantages, including a 4-1 regular-season edge and an NBA Cup semifinal win over the Thunder. The betting lines capture both realities at once: a favorite that looks vulnerable and a challenger whose season-long arc suddenly reads like momentum.
For fans tracking the nba bracket 2026, the question that matters now is whether San Antonio's Game 1 will be a turning point or an outlier. If the Spurs can translate their regular-season and Cup success into multiple wins against a team that had been flawless in the playoffs, the title market will continue to tilt away from Oklahoma City. If the Thunder reset and recover, the favorites' tag — still visible in the futures prices — will harden back into the simplest conclusion the numbers now suggest.
