As the Boston Celtics get ready to host the Philadelphia 76ers for a massive 2025 NBA Playoffs clash this on ABC, I’ve got the perfect way for you to get in on the action. If you haven’t jumped on the Kalshi train yet, you’re missing out. Right now, there’s an exclusive Kalshi promo code BROAD designed specifically for new Kalshi customers that hands you a $10 sign-up bonus once you make just $10 in trades.

I’m taking advantage of this for today’s Boston-Philly matchup, but you can also use your trades to back your guys in any other NBA games happening this week and throughout this round of the playoffs.

Kalshi Promo Code BROAD at a Glance

• Promo Code Required: You must enter the promo code BROAD during the registration process to qualify for the bonus. No code, no bonus—so don’t skip this step.
• New Customers Only: This offer is exclusively available to first-time Kalshi users. If you already have an existing Kalshi account, you are not eligible for this promotion.
• Age Requirement: You must be at least 18 years of age or older to create an account and participate in Kalshi’s prediction markets.
• U.S. Residents Only: You must be physically present in the United States to sign up and trade on Kalshi. The good news? Because Kalshi is a federally regulated exchange (regulated by the CFTC), it is available in all 50 states—no state-by-state restrictions to worry about.
• Minimum Deposit: A first-time deposit of at least $1 is required to activate your account and begin trading. That’s the lowest barrier to entry you’ll find anywhere.
• $10 Trading Threshold: To unlock your $10 sign-up bonus, you must complete a cumulative total of $10 in trades on the platform. This does not need to be a single trade—you can spread it across multiple smaller trades until you hit the $10 mark.
• Bonus Delivery: The $10 bonus is credited to your Kalshi account automatically once the $10 cumulative trading threshold has been met. There is no need to manually claim it.
• No Single-Trade Requirement: You are not required to place your entire $10 in trades on one market or one event. You can diversify across multiple prediction markets, including NBA playoff games, to reach the threshold.
• Identity Verification: As part of the registration process, you will need to provide a valid proof of identification to verify your identity. This is a standard regulatory requirement for all Kalshi users.
• One Bonus Per Customer: The $10 sign-up bonus is a one-time offer. Each eligible user may only claim this promotion once per new account.

Before these two Eastern Conference heavyweights tip off, eligible fans can easily lock in this exclusive welcome offer. As a capacity crowd of up to 18,624 fans fills the arena in Boston, MA, those of us watching from the couch can use the breakdown below to claim our bonus ahead of the 1:00 PM EDT broadcast.

Sixers vs. Celtics Game 1

When making your initial $10 trade to unlock the Kalshi welcome bonus, you can choose to back the home favorite or aim for a massive upset. If you trade $10 on the heavily favored Boston Celtics’ moneyline at -794, a winning prediction would net you approximately $1.26 in profit, resulting in a total payout of $11.26. Conversely, if you place your $10 on the underdog Philadelphia 76ers at +543, a successful trade yields an impressive $54.30 profit for a total return of $64.30.

While specific postseason statistical categories like Net Rate and Total Rebound Percentage are currently unavailable for these two rosters in the provided data, the highly skewed odds offer a clear market perspective. The consensus data strictly positions the Celtics as the significantly safer bet to win outright, leaving the 76ers as a high-risk, high-reward option for traders looking to maximize their potential return on the court today.

Offer Overview

For new Kalshi customers looking to back a side in this intense Celtics-76ers postseason tilt, grabbing this promo code is a total breeze. Here is the deal: to unlock your exclusive $10 sign-up bonus, you just need to create a new account and drop a minimum first-time deposit of at least $1. Honestly, that’s practically couch-cushion money.

From there, your $10 bonus kicks in right after you’ve made $10 in trades on their prediction markets. Whether you’re targeting today’s April 19 matinee at the Garden or eyeing other daily NBA playoff markets, the bonus hits your account as soon as you cross that $10 trading threshold. Because Kalshi is a fully regulated exchange, it’s available in all 50 states, meaning basketball fans coast-to-coast can get a piece of the pie. Just remember, you’ve got to be 18 or older to play, and this offer is strictly for first-time users setting up a new profile.
