Analysis
This represents the market's assessment that California Governor Gavin Newsom has an 82% probability of running for the Democratic presidential nomination in 2028. The high likelihood reflects his current position as a prominent Democratic governor without declared disqualifying factors, though the outcome remains uncertain pending political developments over the next 18+ months. The probability could shift based on changes in Newsom's stated political intentions, major shifts in Democratic Party dynamics, or unexpected personal or professional circumstances. The 2028 Democratic National Convention and any earlier announcements by major party figures will ultimately determine whether this contract resolves affirmatively. Other potential candidates like J.B. Pritzker (74%) and Cory Booker (65%) show measurably lower probabilities, suggesting market participants view Newsom as the leading candidate to enter the race among those listed.
- ›Newsom's public statements and explicit declarations regarding 2028 candidacy will be the primary resolution mechanism
- ›Democratic Party power dynamics and endorsement patterns could shift incentives or viability for any major candidate between now and 2028
- ›Unexpected political or personal developments affecting Newsom's career trajectory or availability could materially alter the probability
- ›Competition or crowding in the Democratic field—including whether other high-probability candidates actually run—affects individual candidate likelihood
- ›Historical patterns show that early 2026-era polling of presidential intentions often diverges substantially from actual 2028 behavior

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.
