Trader consensus on Polymarket reflects skepticism toward an engagement for Kylie Jenner and Timothée Chalamet in 2026, pricing "No" at a 66.5% implied probability amid persistent but unverified rumors. The couple, dating since 2023, has maintained a low-key dynamic with recent public appearances—including PDA at the March 2026 Vanity Fair Oscars afterparty, a beach vacation shared late March, and Coachella sightings in early April—yet no confirmed proposal, ring, or official statements have emerged. Early-year insider reports from outlets like Us Weekly hinted at discussions of marriage and future family plans, but the lack of concrete developments over three months has tempered optimism, underscoring the high uncertainty in celebrity relationships where privacy reigns and announcements remain elusive.
