San Antonio has an 87% win probability tonight, as Victor Wembanyama is primed to put in work against a depleted — and small — Golden State lineup.

The hottest team in the NBA today looks to gain ground in the chase for top spot in the Western Conference as the San Antonio Spurs tangle with the host Golden State Warriors in a marquee matchup Wednesday night.

The Spurs ride a nine-game winning streak into this one, and our senior NBA betting analyst sees an easy night for San Antonio as his Spurs vs. Warriors prediction looks to help you lock down your mid-week NBA picks.

Who will win Spurs vs Warriors?

Spurs win probability: 87% (-669)
Warriors win probability: 13% (+669)

Without Stephen Curry, the Warriors are massive underdogs against the red-hot Spurs, trading at 13 cents (+669) to win, while Victor Wembanyama & Co. are trading at 89 cents (-809) to win their 10th straight game — and 27th in their last 30 games.

Our prediction: Spurs to win

Covers' NBA expert, Jason Logan, notes that the Warriors are just too depleted — missing bigs Al Horford and Quinten Post in addition to Curry — to contend with the Spurs. Wembanyama will have a field day on both ends of the court (including cashing the Over on his rebounding line) as San Antonio cruises to an easy victory.

Our predictions: Spurs -14.5 and Over 227.5 points — NO

San Antonio is one of the NBA's stingiest defenses, with Wembanyama owning the glass and sending shots back against a smaller Warriors lineup tonight. Golden State has been able to score against some of the league's weaker defenses, but the Spurs should have no issues putting the clamps on the Dubs tonight... en route to both a low-scoring game AND a comfortable cover for San Antonio.

What is Kalshi and how does it work?

Kalshi is a federally regulated U.S. exchange where you trade directly on the outcome of real-world future events. Instead of traditional bets, you trade "Event Contracts" which are simple Yes/No questions like "Will the Spurs win tonight?" These events are priced between $0.01 and $0.99, and the prices reflect the market’s estimated probability of that event occurring. For instance, $0.55 equals a 55% chance. If your prediction is correct, the contract pays out exactly $1.00; if not, it settles at $0. Kalshi is essentially a stock market for reality.

How does Kalshi differ from sportsbooks?

In a sportsbook, you bet against the bookmaker, who sets fixed odds and takes a "vig," which is a kind of commission. On Kalshi, you trade against other users. This peer-to-peer model means prices are driven by supply and demand, often resulting in fairer odds. Additionally, because these are financial derivatives, you can exit your position early. If your team takes a 14-point lead, the contract price will rise, allowing you to sell your "Yes" shares for a profit before the final whistle even blows.

Why should I wager on Spurs vs Warriors at Kalshi?

Kalshi offers four unique advantages over traditional sportsbooks:

  1. Flexibility: Unlike a "locked-in" bet, you can sell your contract at any time.

  2. Transparency: You trade against other users, which can allow you to find better value.

  3. Federal regulation: As a CFTC-regulated exchange, your funds are held in a secure, transparent environment.

  4. Availability: Kalshi is available in 49 states (excluding Nevada) and D.C., including many regions where traditional sportsbooks aren't yet legal.
