The Taylor Swift wedding speculation economy experienced a severe correction as multiple markets crashed following weekend revelations. The leading bridesmaid candidate, Cara Delevingne, plummeted from 70¢ to 8¢—a devastating 62-cent drop—after wedding planner Tara Guerard confirmed she was planning a different couple's wedding at Rhode Island's Ocean House on June 13, stating "Taylor is not my bride this weekend!"

Swift-Kelce wedding markets have become a major trading phenomenon since the couple announced their engagement in August with an Instagram post that garnered 37 million likes. The June 13 date had seemed perfect: Swift was born on December 13, making June 13 her half-birthday, and it's the only Saturday falling on the 13th in 2026. But the wedding location market also shifted dramatically, with New York rising to 61¢ while Rhode Island fell to 45¢. Despite the debunking, the couple has remained tight-lipped about their actual wedding plans, leaving traders to navigate a landscape where even the most credible-seeming details can evaporate overnight.
