The Boston Celtics kick off another playoff run against the Joel Embiid-less Philadelphia 76ers, and our 76ers vs. Celtics predictions and NBA picks expect Boston to cruise to victory in Game 1 this afternoon.

Who will win 76ers vs Celtics Game 1?

76ers win probability: 14% (+614)
Celtics win probability: 86% (-614)

In the last three games the Philadelphia 76ers played in Boston without the big man, they were outscored by 17.3 points per game. The Boston Celtics sport a +8.3 net rating at home this season, and with the team close to full strength, I’ll back them to win this one by 13+.

Our prediction: Celtics to win

Without Embiid, Philly’s offensive rating dipped from 118.5 to 112.9, good for eighth-worst. Philly will have trouble scoring, and I expect Boston to cruise.

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 Celtics 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 76ers vs Celtics 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.
