Polymarket NBA Finals 2026: Spurs vs Knicks Odds + Game-by-Game Markets

The 2026 NBA Finals are set: San Antonio Spurs vs New York Knicks, tipping off Wednesday, June 3 in San Antonio. Polymarket's championship market has crossed $404 million in volume, with the Spurs favored at 61% and the Knicks at 38%. Victor Wembanyama's Spurs have home court after a 62-20 regular season. Here's how the markets are pricing the series.

2026 NBA Championship Odds (June 1, 2026)

The championship market is the biggest NBA market on Polymarket, with $404.1 million traded. With both conference finals over, only two teams remain:

Team	Probability	Price	Profit per $1 Share
San Antonio Spurs	61%	$0.61	$0.39
New York Knicks	38%	$0.38	$0.62

The two prices add to roughly 99 cents, with the remaining 1% representing the standard prediction market spread. The Spurs price held above 60% throughout the Thunder series even after going down 2-1, which signals strong dealer conviction in Wembanyama's two-way impact.

How We Got to Spurs vs Knicks

Eastern Conference Finals: Knicks sweep Cavaliers

The Knicks closed Cleveland out 4-0, finishing the sweep on May 28. Jalen Brunson averaged 32 points across the four games and Karl-Anthony Towns shot 56% from the field. The Eastern Conference Champion market resolved at $0.99 for Knicks shareholders who held through the sweep.

Western Conference Finals: Spurs beat Thunder in Game 7

This was the better series. The Thunder were defending champions and held home court, but San Antonio took Game 6 in the Alamodome to force a seventh game. Wembanyama posted 28 points, 14 rebounds, and 6 blocks in Game 7 on May 30 and was named Western Conference Finals MVP. The Spurs price on Polymarket jumped from $0.40 to $0.61 within hours of the Game 7 final whistle.

Types of NBA Finals Markets on Polymarket

Championship Futures

The "2026 NBA Champion" market is a binary at this point — Spurs or Knicks. Prices update with every game and key injury report. A Knicks Game 1 road win could push their price from $0.38 to $0.50 or higher.

Series Markets

The "Spurs vs Knicks series winner" market tracks the same probability as the championship market, with slightly tighter spreads since there are only two outcomes.

Exact Series Outcome

Polymarket runs a separate market on how the series ends (Spurs in 4, Spurs in 5, Spurs in 6, Spurs in 7, Knicks in 4, Knicks in 5, Knicks in 6, Knicks in 7). The most-bet outcome is Spurs in 6 at roughly $0.21, followed by Spurs in 7 at $0.16 and Spurs in 5 at $0.14.

Game Markets

Each Finals game has its own straight-up winner market. These open the day before the game and resolve within hours. Game 1 odds opened with the Spurs at -180 (roughly 64% implied).

Finals MVP

Wembanyama leads the Finals MVP market at 44%, with Brunson at 29%, Towns at 9%, and Stephon Castle at 7%. Devin Vassell and OG Anunoby are the longshots in the 4-6% range.

Player Props

Prop markets cover total points, rebounds, assists, and threes made per game. Lower liquidity than team markets, but better value if you track player-level matchup data. Wembanyama vs Towns in the post is the most-watched prop matchup of the series.

Trading Strategies for the Finals

1. Game 1 Volatility Trade

Game 1 prices typically move 8-15 percentage points in the championship market depending on the result. If the Spurs win Game 1 at home, they'll likely climb to $0.70+. A Knicks road win pushes them to $0.50 or higher. Both moves create exit opportunities for traders who entered Game 7 of the Western Finals at lower prices.

2. Buying the Underdog After Game 1 Loss

History shows the team losing Game 1 still wins the Finals about 33% of the time. If the Knicks lose Game 1 and their price drops to $0.30, the implied probability of winning the series is actually similar to the historical base rate. That can be the cheapest entry point of the series for Knicks bulls.

3. Exact Series Outcome Arbitrage

The sum of all "Spurs in X" prices should equal the Spurs' championship price, and the same holds for Knicks. When this relationship breaks (usually right after a game result), there's a brief arbitrage window. Buy the under-priced specific outcome and sell the over-priced championship futures.

4. Live Game Trading

NBA game markets stay open during the game. Prices move on every possession in the fourth quarter. Tips for live trading:

• Watch the game live. Polymarket price updates can lag the score by 30-60 seconds.
• Foul trouble on Wemby or Brunson creates the biggest swings.
• Use limit orders instead of market orders to avoid paying wide spreads in the fourth quarter.
• Pre-set your sell price before the game starts. Live trading on emotion costs money.

5. MVP Hedge Against Team Position

If you hold a large Knicks championship position, buying a small Brunson MVP position acts as a hedge. The two markets move together but at different magnitudes, so the MVP position absorbs some of the volatility if New York pulls the upset.

Risk Management

A few specific risks for Finals trading:

• Wembanyama injury risk. Any in-game foul trouble or tweak shifts the Spurs' price by 5-10 points within minutes. Size positions assuming this can happen.
• Don't chase Game 1 results. A team that wins Game 1 still loses the series often enough to matter. The price move after Game 1 frequently overshoots.
• Position sizing. Cap single-game positions at 5% of bankroll and championship futures at 10%.
• Order book depth. Check the order book before placing larger trades. NBA Finals markets are deep, but late-game live orders can move price more than you expect.
