On May 27 (UTC+8), the pivotal Game 5 of the NBA Western Conference Finals concluded in Oklahoma City. The defending champion Oklahoma City Thunder defeated the San Antonio Spurs at home, 127-114, taking a 3-2 lead in the series and moving just one win away from returning to the NBA Finals. At the same time, Polymarket’s 2026 NBA champion prediction market immediately adjusted its odds—the Thunder’s championship probability surged to 57%, the Knicks followed at 29%, and the Spurs dropped to 15%.
While the Eastern Conference champion Knicks have been waiting for the Finals for eight days, the outcome of the Western Conference’s decisive matchup has just been settled—the suspense surrounding the championship continues to evolve with each playoff game.
Game 5 Recap: Thunder 127-114 Over Spurs, SGA Delivers 32 Points
In Game 5 on May 27, the Thunder demonstrated the dominance expected of defending champions, even without Jalen Williams and Mitchell. All-Star guard Shai Gilgeous-Alexander scored 32 points—though he shot just 7-for-19 from the field, his efficiency at the free-throw line (16-for-17) anchored the Thunder’s offense. Alec Caruso, coming off the bench, contributed 22 points, while Jared McCain, starting in place of Jalen Williams, put up 20 points in his first playoff start—18 of those came in the second half.
The Thunder’s frontcourt duo also played reliably: Chet Holmgren recorded 16 points and 11 rebounds, and Isaiah Hartenstein added 12 points and 15 rebounds. On the Spurs side, Victor Wembanyama struggled, shooting only 4-for-15 for 20 points and 6 rebounds, unable to replicate his dominant performances from earlier games. The Spurs shot just 12-for-41 from three-point range, and their poor perimeter shooting proved decisive in their defeat.
The Thunder exploded for 40 points in the second quarter, establishing an early lead that they maintained until the final buzzer. Both teams combined for 29 made free throws in a single quarter, setting a new NBA playoff record for most free throws made in one quarter since the 2020 bubble postseason.
With this win, the Thunder now lead the series 3-2 and hold match point. Game 6 will shift to San Antonio on May 29 (UTC+8). If the Spurs tie the series, a decisive Game 7 will return to Oklahoma City on May 31.
In-Depth Analysis of Latest Championship Odds: Thunder Lead at 60%
Following the Thunder’s Game 5 victory, Polymarket’s championship odds were quickly and significantly updated. According to the latest Polymarket data, the current championship probabilities are: Thunder 57%, Knicks 29%, Spurs 15%.
Thunder: 57%—Market Confirms the Defending Champions’ Dominance
The market’s high valuation of the Thunder is driven by three key factors:
First, match point advantage. The Thunder lead 3-2 and are just one win away from the Finals. While Game 6 shifts to the Spurs’ home court, even if the Thunder lose, they retain home-court advantage for Game 7. Historically, in NBA best-of-seven playoff series, the team that wins Game 5 has about an 82% chance of advancing.
Second, depth proven under adversity. Despite missing both Jalen Williams and Mitchell, the Thunder still scored 127 points to defeat the Spurs. McCain’s performance as a starter and Caruso’s steady contributions off the bench demonstrated that the Thunder maintain elite competitiveness even when shorthanded.
Third, experience gap with Finals opponent. Although the Knicks swept the Cavaliers to advance, their core roster lacks Finals experience. In contrast, the Thunder, as defending champions, have a clear advantage in handling high-pressure situations.
Knicks: 29%—Rest and Recovery Remain Their Biggest Asset
The Knicks’ championship probability dropped from around 40% to 29%, not due to their own performance, but because of changing dynamics in the West. With the Thunder winning Game 5, the Knicks are now more likely to face them in the Finals instead of the Spurs—and the Thunder’s roster presents natural matchup challenges for the Knicks in several key areas.
Nevertheless, the Knicks’ physical advantage remains a significant variable. Since sweeping the Cavaliers on May 26, they have enjoyed eight days of rest. According to injury reports, no Knicks players are currently listed as injured. In the high-intensity environment of the playoffs, physical condition and health are often decisive factors in a series.
Spurs: 15%—Wembanyama Struggles Alone, Market Confidence Drops
The Spurs’ championship probability fell from 19% to 15%, a relatively modest decrease. The market hasn’t lost all confidence after a single loss, but Wembanyama’s inefficient 4-for-15 shooting in Game 5 has raised questions about the 22-year-old superstar’s reliability under pressure.
Still, a 13% probability means the market sees a real chance for the Spurs to tie the series in Game 6. If they defend home court and force a Game 7, their championship odds could be recalibrated.
