The most profitable World Cup trade this month was not a Polymarket bet but a surge in Tinder activity that lifted Match Group (MTCH) stock. The stock had fallen 12% before the tournament began on June 11, but has since climbed 13%, erasing losses and approaching yearly highs. Tinder matches rose almost 60% in the US during the first six days, with total users up 15% and international fan activity in host cities climbing 47%. This engagement data buoyed the stock, which closed at $37.17 on June 26 after a 6.4% jump. The rebound builds on a longer turnaround story: Tinder had lost users for nearly two years, but returned to user growth in March under new CEO Spencer Rascoff. While Polymarket and Kalshi drew betting attention, Match Group offered a quieter trade on the same event. However, caution remains as Tinder paying users fell 5% in Q1, meaning engagement hasn't fully translated to revenue. The final on July 19 will test whether the boost outlasts the tournament.
