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

Why this matters:
This contract asks whether Donald Trump will publicly announce another presidential campaign before January 1, 2028. At 21%, the market suggests this outcome is unlikely but material—roughly one-in-five probability. The relatively low odds may reflect Trump's current focus on other political activities and the early timeframe; candidates often delay formal announcements until closer to election cycles. Key drivers include Trump's recent legal proceedings, his involvement in 2026 midterm endorsements, and whether he signals 2028 intentions through statements or political positioning. The most significant near-term catalyst would be Trump's public statements regarding his political future, particularly any declaration of candidacy or explicit statements ruling out another run. Market participants are also tracking his media activity and political priorities as indirect signals of 2028 intentions.

Key factors:
- Trump's current legal exposure and ongoing cases, which could affect timing and likelihood of a 2028 announcement
- His pattern of political engagement in 2026 midterms—heavy involvement might suggest focus on party influence rather than personal candidacy
- Previous historical patterns: Trump announced his 2020 campaign in June 2015 and 2024 campaign in November 2022, suggesting late-cycle timing is typical
- Media statements or Truth Social posts explicitly addressing 2028, either confirming or denying intent to run
- The competitive Republican primary field and whether Trump faces credible challengers who force earlier clarification of his status

## 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.
