Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
This market estimates a 67% probability that JD Vance will publicly announce a presidential campaign before April 1, 2027. As Vice President, Vance has roughly 11 months to make such an announcement. The probability reflects expectations about his political positioning and strategic timing relative to the 2028 general election cycle. Markets on competing candidates show substantially lower implied probabilities: Gavin Newsom at 14% and Nikki Haley at 4% for announcements before 2027. Vance's position in the current administration and his political base among Trump-aligned voters create different incentive structures than opposition candidates. The main uncertainties driving this level involve whether Vance views an early announcement as advantageous versus waiting until closer to 2028, and how political dynamics evolve over the next year. Key upcoming moments include the 2026 midterm elections in November and major political events in early 2027.

Key factors:
- Vance's statement frequency and positioning regarding 2028 succession planning increases or decreases probability of announcement
- Changes in Trump's own public statements about his 2028 intentions directly affect Vance's strategic timing calculus
- Major political realignments or shifts in Republican primary dynamics between now and April 2027 could accelerate or delay announcement timing
- Historical precedent: sitting Vice Presidents typically announce runs 6-12 months before election year, suggesting late 2027 or early 2028 as baseline expectation
- Competing market probability for Newsom announcement (14%) and Haley announcement (4%) reveal relative market expectations about each candidate's incentive to announce early

## 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.
