After treating their fans to a 111–98 victory in Game 1, the San Antonio Spurs will look to keep home-court advantage intact with another win against the Portland Trail Blazers tonight.
We break down Kalshi’s win probability markets and deliver some Trail Blazers vs. Spurs predictions to help guide your NBA picks for Tuesday, April 21.
Who will win Trail Blazers vs Spurs Game 2?
Trail Blazers win probability: 16% (+525)
Spurs win probability: 86% (-614)
Trading at 79¢ before the series opener, San Antonio is an even heavier favorite heading into Game 2, currently listed at 86¢.
Our prediction: Spurs to win
Victor Wembanyama has officially arrived. Not to overreact to an easy Game 1 win, but this version of the San Antonio Spurs should be feared by everyone in the NBA.
The Trail Blazers had a delightfully surprising season, but it would be an act of mercy by the NBA to shorten this series to best-of-five, if not best-of-three.

Our predictions: Over 219.5 points — No
The one thing the Trail Blazers should carry over from Game 1 is slowing down the pace. Fewer possessions give San Antonio fewer chances to enjoy its talent advantage.
Six of Portland's final eight regular-season games also cashed the Under.

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 Trail Blazers vs Spurs at Kalshi?
Kalshi offers four unique advantages over traditional sportsbooks:
- Flexibility: Unlike a "locked-in" bet, you can sell your contract at any time.
- Transparency: You trade against other users, which can allow you to find better value.
- Federal regulation: As a CFTC-regulated exchange, your funds are held in a secure, transparent environment.
- Availability: Kalshi is available in 49 states (excluding Nevada) and D.C., including many regions where traditional sportsbooks aren't yet legal.
