90% — Will Donald Trump meet in person Pope Leo XIV before Jan 1, 2027 Leader: Mark Carney at 90% · Kalshi 90% · 19 contracts · $217 volume · medium confidence Updated 2026-06-08 02:30:21 UTC Tracks the leading outcome in a winner-take-all prediction market set with 19 outcomes. Why this matters: This contract predicts whether Donald Trump will meet Pope Leo XIV in person before January 1, 2027—roughly 8 months from now. The 93% probability reflects that market participants view an in-person papal meeting as highly likely within this timeframe. The main drivers are Trump's diplomatic schedule, papal availability, and logistical feasibility of arranging a Vatican visit. Historical precedent shows U.S. presidents often meet popes during their terms, though scheduling depends on both parties' travel plans and diplomatic priorities. The biggest catalyst would be any announced papal or presidential trip to Rome, or public statements about planned meetings. Conversely, the probability could shift if Trump's international travel becomes constrained or if diplomatic tensions affect scheduling. Key factors: - Trump's current status as former president (not sitting president) may reduce the likelihood of a formal Vatican state visit compared to his 2017-2021 tenure - Pope Leo XIV's age and health status directly affects capacity to receive visitors and hold audiences - Scheduled diplomatic travel by Trump or papal events in 2026 would be observable leading indicators of meeting feasibility - Vatican scheduling practices typically require weeks of advance planning; any announced meeting would likely become public within months - Historical frequency: U.S. presidents have met popes regularly, but retired presidents meet them less often than sitting executives Contracts: - Will Donald Trump meet in person Mark Carney before Jan 1, 2027?: Mark Carney — 90¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Sam Altman before Jan 1, 2027?: Sam Altman — 90¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Recep Tayyip Erdoğan before Jan 1, 2027?: Recep Tayyip Erdoğan — 89¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Mohammed bin Salman before Jan 1, 2027?: Mohammed bin Salman — 78¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Ahmed al-Sharaa before Jan 1, 2027?: Ahmed al-Sharaa — 71¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Mark Zuckerberg before Jan 1, 2027?: Mark Zuckerberg — 65¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Claudia Sheinbaum before Jan 1, 2027?: Claudia Sheinbaum — 63¢ Kalshi $0 (weight 0%) - Will Donald Trump meet in person Peter Thiel before Jan 1, 2027?: Peter Thiel — 44¢ Kalshi $0 (weight 0%) - ... and 11 more --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question.
