There's nothing quite like the electric atmosphere of a Game 7 in the NBA Playoffs. As the Boston Celtics prepare to host the Philadelphia 76ers at TD Garden for their decisive May 2 matchup, the stakes couldn't be higher. If you've been watching from the sidelines while others turn playoff passion into profit, now's your chance to get in on the action. By signing up with the Polymarket promo code TSNEWS, new users can claim a $20 welcome bonus to trade on tonight's historic clash—and every other playoff game this week.

Here's how it works: make an initial deposit of at least $20, and you'll unlock a $20 sign-up bonus automatically. That means you can start trading on everything from the Celtics-76ers showdown to other postseason matchups without risking your own cash. It's a simple, low-pressure way to add some serious excitement to the games you already love.

Before we dive into the key angles for tonight's tip-off on NBC and Peacock, let's break down the offer. This exclusive promotion is for new Polymarket customers only, but grabbing your bonus is straightforward. Just register a new account, make your first deposit of $20 or more, and the bonus will be ready to deploy on this win-or-go-home battle in Boston.

And what a battle it promises to be. The 76ers forced this Game 7 after storming back from a 3-1 series deficit, injecting maximum drama into an already legendary 2026 postseason rivalry. With Jayson Tatum and Tyrese Maxey set to take the floor, every possession matters. The market is already pricing this matchup, and savvy traders are looking for the best edges.

Just remember the ground rules: you must be 18+ and physically located in an eligible Polymarket state. As long as you meet those criteria and are making your first deposit, securing your $20 bonus before tip-off is a breeze. So gear up, place your trades, and enjoy the ride—Game 7s don't come around every day, but when they do, you want to be in the game.
