Mavericks vs. Rockets prediction, odds and best bet for Oct. 21, 2026

The Houston Rockets are favored to beat the Dallas Mavericks on Wednesday, according to Dimers' NBA pregame model.

Our Mavericks vs. Rockets prediction gives Houston a 77.7% chance of winning at Toyota Center, but the latest odds suggest value in betting on the Mavericks to cover the +9.5 spread.

Mavericks vs. Rockets: Key predictions

• Rockets win probability: 77.7%
• Mavericks win probability: 22.3%
• Mavericks +9.5 spread: 54.0% cover probability
• Under 230.5 points: 52.3% probability

Dimers' NBA pregame model estimates how many points each team is likely to score, accounting for factors such as recent player performance, each team's strengths and weaknesses, projected playing time, player availability, and home-court advantage.

These projections power our NBA predictions, which show the probability of each team winning, covering the spread, and the total points going over or under the betting line.

Best value bet: Mavericks +9.5 (51¢)

The Rockets may be more likely to win, but Dimers' top value bet is the Mavericks to cover the +9.5 spread at 51¢, available at Kalshi.

Those odds imply the Mavericks have a 50.7% chance of covering, while our model puts that probability at 54.0%.

That's a 3.2% edge (accounting for rounding) in the Mavericks' favor, the largest across the moneyline, spread, and total points markets based on Dimers' probabilities and the best available odds.
