Analysis

This 30% probability represents market participants' assessment that a particular Democratic candidate will be nominated as Vice President in 2028. The current leader appears to be a relatively obscure figure, with Ro Khanna showing the highest trading volume at 39 cents. The probability reflects early-stage uncertainty: the 2028 Democratic presidential nominee hasn't been selected, and VP choices typically occur after that decision. Key drivers include the eventual nominee's strategic calculus about geographic balance, ideological positioning, and demographic appeal. The probabilities will likely shift substantially once the Democratic primary concludes and the presidential nominee announces their running mate selection, expected in summer 2028. Currently, low trading volumes suggest limited market conviction across most candidates.

  • The 2028 Democratic presidential nominee has not yet been determined; VP selection typically occurs only after the nominee is decided, making current VP odds highly speculative.
  • Ro Khanna (39¢) leads despite representing roughly 4% implied probability, indicating thin liquidity and potentially unrepresentative pricing in a 19-way market.
  • Total contract volume is modest ($220 in the top contracts over 24 hours), suggesting limited participation and potential for significant repricing with increased activity.
  • Historical VP selections depend heavily on the eventual presidential nominee's identity and strategic priorities, making current individual candidate odds disconnected from actual decision-making.
  • The resolution date is approximately 28 months away, providing ample time for political developments, candidate viability changes, and market reassessment.

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.
