Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
This market estimates a 12% chance that Donald Trump will meet in person with Iran's Supreme Leader before January 1, 2027, with only a 4% probability such a meeting occurs by August 1, 2026. The low probability reflects the historical rarity of direct presidential-to-Supreme Leader engagement and current geopolitical tensions. The main drivers are diplomatic signals from either government and any scheduled international summits or negotiations. The probability would likely increase substantially if either party publicly announced talks or if a credible intermediary reported active negotiations. Near-term resolution depends on whether any official meeting is scheduled and held before the August 1 date, though the January 2027 contract allows for a longer diplomatic window.

Key factors:
- No direct Trump-Supreme Leader meeting has occurred since 2017; current U.S.-Iran relations remain adversarial with active sanctions
- The August 1, 2026 deadline is 46 days away with no announced plans for such a meeting as of the current date
- The 12% January 2027 contract suggests markets assign only 8% additional probability to a meeting occurring in the five-month September-December 2026 window
- Diplomatic breakthroughs typically involve weeks or months of preliminary talks; a surprise unannounced meeting would be unprecedented in modern U.S.-Iran relations
- Calendar timing matters: major diplomatic meetings typically require advance scheduling and preparation, making spontaneous encounters highly unlikely

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
