**Strong trader consensus around a 91.5% implied probability for “Yes” on Zoe Kravitz and Harry Styles being engaged by August 31 stems primarily from multiple credible reports confirming their engagement in April 2026.** After roughly eight months of dating that began with public sightings in August 2025, sources at People and Page Six detailed the proposal, noting Kravitz had been showing friends her diamond ring and that the couple informed a small inner circle. Subsequent sightings, including a June 2026 London date and an early August picnic in Mexico City during Styles’s tour break, have reinforced their status as an engaged pair actively discussing wedding plans. While the high odds reflect this established timeline and ongoing public appearances, a realistic challenge could arise if the market requires an official joint statement or formal announcement before the August 31 cutoff, given the couple’s preference for privacy.
