Analysis

J.D. Vance is currently priced at 18% to win the 2028 presidential election, making him the leading candidate among markets tracking this outcome. This probability reflects traders' assessment of his viability as a general election candidate relative to other potential nominees from both parties. The current level is influenced by Vance's position within Republican politics and market perception of Democratic alternatives. Near-term factors that could shift this probability include major political developments, polling changes, or clarifying events regarding other candidates' viability. The outcome ultimately depends on nomination contests in 2028 and subsequent general election dynamics, though the market currently suggests substantial uncertainty with multiple candidates clustered in the 15-18% range.

  • J.D. Vance's 18% price is only 2 percentage points ahead of Gavin Newsom (16%) and 3 points above Marco Rubio (15%), indicating high fragmentation rather than consensus favorite
  • 24-hour trading volume for Newsom ($11,963) significantly exceeds volume for Vance ($7,677), suggesting more active positioning in alternative candidates
  • The combined price of top five candidates totals roughly 57%, leaving 43% for all other potential nominees—indicating material uncertainty about the eventual nominee
  • Donald Trump is priced at only 3% despite recent political prominence, while Kamala Harris is at 5%, showing markets heavily discount recent officeholders
  • The 2028 nomination contests have not yet occurred, and no formal candidacies are established, making current prices highly responsive to political developments and early polling shifts

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.
