Trade on Cavs vs. Mavs for $10 Bonus
For Cavs vs. Mavs (Friday, March 13, 7:30 p.m. ET on Prime Video), think in contracts, not point spreads. You pick a Yes/No market, buy shares at the current price, and your position value moves as the market reprices.
Here's an easy example: you open a $10 position on a Cavaliers-related contract priced at $0.55 per share, so you’re holding about 18 shares (since 18 x $0.55 = $9.90). If the contract settles Yes, those shares settle at $1.00 each, so your payout is about $18 and your profit is roughly $8.10 before fees (see full terms). If it settles No, the shares settle at $0 and you lose what you put in, which is why the $10 credit from code ACTION can matter on your next trade.
Use the Kalshi promo code ACTION when you sign up, then keep your next move simple: use the promo credit to size a second position without adding more cash right away. Use the NBA Prime Video schedule as a starting point to trade your $10 bonus on more action through the weekend.
