The NBA Play-In Tournament tips off Tuesday, and fans looking to put a little more on the line than bragging rights have several new-code offers to choose from this week. The NBA playoffs start Saturday, giving the next few days a tight window for anyone hoping to use prediction market apps around Hornets-Heat or Suns-Trail Blazers.
WTOP says new users can sign up with Kalshi promo code WTOP and qualify for a $10 sign-up bonus after making $10 worth of trades. The same roundup says Polymarket promo code WTOP offers a $20 welcome bonus with a cash deposit of at least $20, while Novig promo code WTOP gives a 10% discount on a first trade up to $100, plus 1,000 Novig Coins and five Novig Cash. OG is also offering five consecutive days of 100% profit boosts for new accounts.
That pitch lands at a moment when NBA betting interest usually sharpens fast, with the Play-In Tournament serving as the last stop before the bracket turns into the playoffs. The games this week give fans a short runway to test the apps and the offers, all while the league moves into its most watched stretch of the season.
The catch is that each promotion comes with its own terms, and the money involved is not the same across the board. Kalshi’s bonus requires trades, Polymarket’s requires a deposit, Novig’s discount tops out at $100, and OG’s boost applies only for five straight days, so the better deal depends on how a user plans to play the week rather than on the headline number alone.
For NBA followers, that makes Tuesday and Saturday the dates that matter most. The Play-In Tournament starts first, the playoffs begin three days later, and the offers from Kalshi, Polymarket, Novig and OG are built to catch fans in between.
