NBA Finals Are Just One Step Away: Use Gate’s Prediction Market to Understand Each Team’s Latest Championship Probability

Beijing time on May 27, the NBA Western Conference Finals’ pivotal Game 5 in Oklahoma City came to an end. The defending champion Oklahoma City Thunder beat the San Antonio Spurs 127-114 at home, rewriting the series to 3-2 and leaving them just one step away from returning to the Finals. Meanwhile, on Polymarket’s 2026 NBA Championship prediction market, the probability estimates were adjusted immediately: the Thunder’s title odds surged to 57%, the Knicks moved into second place with 29%, and the Spurs dropped to 15%.

With the Eastern Conference champion Knicks having already waited eight days for the Finals, the decisive battle of the Western Conference Finals has only just been decided—how the suspense around who will claim the championship continues to evolve with every step of the playoffs.

Western Conference Finals Recap: Thunder 127-114 Spurs, SGA’s 32 points deliver the win

In the May 27 pivotal Game 5, the Thunder—without Jalen Williams and Mitchell—displayed the kind of dominance a defending champion was expected to bring. All-Star guard Shai Gilgeous-Alexander scored 32 points. Although he went just 7-of-19 from the field, his 17-of-16 free-throw efficiency ensured the Thunder’s offensive foundation. Coming off the bench, Alex Caruso added 22 points. And Jared McCain, who started in place of Jalen Williams, scored 20 points in his first playoff start—18 of which came in the second half.

The Thunder’s interior duo also performed steadily: Chet Holmgren finished with 16 points and 11 rebounds, while Isaiah Hartenstein contributed 12 points and 15 rebounds. By contrast, for the Spurs, Victor Wembanyama went 4-of-15 for the game, scoring 20 points and grabbing 6 rebounds, unable to carry forward the dominant level of offense and defense from the previous games. The Spurs attempted 41 three-pointers and converted only 12; their poor shooting from beyond the arc was a key factor in the loss.

The Thunder poured in 40 points in the second quarter, establishing a lead early and then holding it all the way to the final buzzer. Across both teams, they combined for 29 made free throws in a single quarter, setting a new NBA playoff record for the most free throws made in one quarter since the 2020 bubble playoffs.

With this win, the Thunder changed the series score to 3-2 and now hold the series point. Game 6 will move to San Antonio on May 29 Beijing time. If the Spurs manage to tie the series, Game 7 will return to Oklahoma City on May 31.

Latest Deep Dive on Championship Probabilities: Thunder breakaway leads at 60%

Following the Thunder’s victory in the pivotal Game 5, Polymarket’s championship probability immediately underwent a major adjustment. According to Polymarket’s latest data, the current championship odds for each team are: Thunder 57%, Knicks 29%, Spurs 15%.

Thunder: 57% — Market confirms the reigning champion’s dominance

The market’s high pricing for the Thunder is grounded in three key points:

First, the series point advantage. The Thunder currently lead 3-2 and are only one win away from returning to the Finals. Although Game 6 moves to the Spurs’ home court, even if the Thunder lose Game 6, they still have home-court advantage in Game 7. Historical data shows that in NBA best-of-seven playoff series, the team that wins the pivotal Game 5 (the must-win game) advances with about an 82% chance.

Second, depth validated in adversity. In this game, with Jalen Williams and Mitchell both out, the Thunder still defeated the Spurs with a high-scoring 127-point output. McCain’s strong start and Caruso’s steady bench production showed the market that even with limited personnel, the Thunder still possess top-tier competitiveness.

Third, the experience gap of the Finals opponent. The Knicks advanced by sweeping the Cavaliers, but the team’s core roster generally lacks Finals experience. In comparison, as the defending champions, the Thunder clearly have the advantage in handling high-pressure situations.

Knicks: 29% — Physical reserves remain the biggest trump card

The Knicks’ championship probability fell from around 40% to 29%. The main reason is not that their own performance has declined, but that the competitive landscape in the Western Conference has changed. After the Thunder took Game 5, the Knicks will most likely face the Thunder—not the Spurs—in the Finals. And the Thunder’s roster setup has natural advantages over the Knicks in several key matchup areas.

Even so, the Knicks’ edge in physical condition is still an important variable that cannot be ignored. Since sweeping the Cavaliers and advancing on May 26, the Knicks have had as many as eight days to rest. Judging from injury reports, no Knicks player is currently listed on the injury report. In playoff series with this kind of high-intensity competition, physical condition and health are often among the most decisive factors for determining the course of a series.

Spurs: 15% — Wembanyama can’t carry it alone, market confidence cools

The Spurs’ championship probability dropped from 19% to 15%, a relatively limited decline. The market has not completely lost confidence in the Spurs due to a single loss. However, in the pivotal Game 5, Wembanyama’s efficiency—15 shots with only 4 made—does raise fresh questions about the stability of this 22-year-old rising star when the pressure is highest.

Still, a 13% probability means the market is leaving the Spurs with a meaningful chance to tie the series in Game 6. If the Spurs can defend their home court in Game 6 and force a Game 7, their championship odds would have room to be repriced again.

• Uncertainty of outcomes: Even with a 60% championship probability, there is still a 40% chance they won’t win. Prediction markets reflect market consensus, not a guaranteed future.
• Emotional resonance risk: The high volume of discussion in the event comment section can form an information echo chamber. It’s recommended to cross-verify with information from multiple dimensions.
• Reasonable position allocation: Prediction market features should be used as an auxiliary decision tool to avoid over-concentrating on a single event or putting in funds beyond your capacity to bear.
