Tracks the leading outcome in a winner-take-all prediction market set with 3 outcomes.

Why this matters:
This reflects a 40% probability that Justice Clarence Thomas will publicly announce his resignation before January 1, 2028. The market is pricing in uncertainty around Thomas's health and potential retirement timeline. At 83, Thomas is the Court's oldest member; health developments or major life changes would significantly shift expectations. Recent Supreme Court term conclusions and congressional leadership transitions could influence retirement timing decisions. The key catalyst will be any public statements from Thomas, his family, or Court insiders regarding his future plans, along with observable changes in his docket participation or health status over the coming months.

Key factors:
- Thomas is 83 years old with a history of health issues; medical events or public health disclosures could materially shift retirement probability
- Market pricing shows higher conviction for departure before Jan 1, 2028 (40%) versus before Jan 1, 2027 (11%), suggesting traders expect departure is more likely mid-2027 or later if it occurs
- Control of the presidency and Senate affects strategic retirement timing; the current political environment influences when justices choose to announce departures
- Thomas has not signaled imminent retirement publicly; absence of health crises or explicit statements keeps near-term probabilities relatively low
- Historical precedent shows justices typically announce departures months in advance; sudden announcements are uncommon

## 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.
