Bracket families

3 clusters across 5 contracts.

These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.

Heads-up — heterogeneous clusters

The top two clusters share only 25% of their title tokens — “Will Donald Trump announce a run for President of the United States before” vs “Who will run for the Republican presidential nomination in 2028”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

Donald Trump is currently viewed as having low odds of announcing a 2028 presidential run, with markets pricing that event at 26% by November 2028. There is a 44% market-implied probability that Trump will endorse J.D. Vance for the 2028 election before March 1, 2028. Conversely, market participants assign only an 11% probability to Trump endorsing himself.

  • 26% chance of Trump 2028 run announcement
  • 44% chance of J.D. Vance endorsement
  • Low 11% odds for Trump self-nomination
  • Early political maneuvering

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.
