Analysis

This probability indicates the market's assessment that Trump has a 15% chance of becoming the Republican presidential nominee. As of August 2026, this relatively low probability reflects market perception that other candidates are viewed as more likely to secure the nomination. The current level would move based on Trump's standing in primary polls, his legal situation, and endorsements from party establishment figures. The Republican National Convention in 2028 represents the key event that will definitively resolve this outcome, though primary elections and early state contests beginning in late 2027 will provide significant clarity on the trajectory of the nomination race.

  • Trump's standing in early Republican primary polling relative to leading alternatives like Vance (43¢), Rubio (22¢), and DeSantis (5¢)
  • Status of ongoing legal proceedings and their potential impact on his eligibility or political viability
  • Support from Republican establishment figures and current party leadership direction
  • Performance in early primary contests scheduled for late 2027 and early 2028
  • Turnout and vote share trends in states that hold the earliest nominating contests

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
