Spurs top title probabilities as Philadelphia gains in latest market snapshot

Oklahoma City is second at 16 percent on Kalshi and 13 percent on Polymarket in the November 5 reading, with Philadelphia third at 15 percent on Kalshi, up 2 points in 24 hours. Rivo updated its Kalshi odds board at 4:51 AM ET on November 5.

San Antonio Spurs hold the highest probability in the 2027 NBA Championship market, at 23 percent on both Kalshi and Polymarket, according to Rivo’s November 5 reading.

Oklahoma City trails San Antonio

Oklahoma City ranks second on both platforms, but its probability differs between them: 16 percent on Kalshi and 13 percent on Polymarket, according to Rivo.

Those readings put Oklahoma City 7 percentage points behind San Antonio on Kalshi and 10 percentage points behind on Polymarket. San Antonio’s matching probabilities contrast with the 3-percentage-point difference for Oklahoma City.

Philadelphia moves higher on Kalshi

Philadelphia is third on Kalshi at 15 percent, having gained 2 percentage points in 24 hours, according to Rivo. That leaves it 1 percentage point behind Oklahoma City on that platform.

Rivo updated its Kalshi odds board at 4:51 AM ET on November 5. The report was published on Nov 5, 2026, at 5:00 AM ET; the supplied summary does not include a Polymarket probability for Philadelphia.

What it means for prediction markets

  • San Antonio leads both platforms at 23 percent, but that probability remains well below a majority likelihood of winning the championship.
  • Oklahoma City’s 16 percent Kalshi reading and 13 percent Polymarket reading show that the platforms agree on its ranking, not its probability.
  • Philadelphia’s 2-percentage-point rise brings it close to second place on Kalshi. Without a supplied Polymarket reading, a cross-platform comparison for Philadelphia is not possible.
