There’s been a lot of negativity for the Boston Celtics since missing out on Giannis Antetokounmpo. Since then, they’ve signed center Mitchell Robinson from the Knicks, but quickly traded Jaylen Brown to the 76ers for pennies on the dollar. Kalshi negatively adjusted its price accordingly.
Boston’s shift on Kalshi’s NBA market saw a 12% drop, going from 19% to a 7% chance to win the 2026-27 NBA Finals after trading away Brown.
