Analysis

This contract estimates the likelihood that candidates explicitly backed by Elon Musk will win at least one U.S. House or Senate seat in the 2026 midterm elections. The 16% probability reflects skepticism about whether Musk's endorsements and campaign support will translate into electoral victories, though the exact threshold for "Musk-backed" remains subject to interpretation. The primary drivers are the strength of these candidates' local positioning, whether Musk maintains visible engagement in specific races, and whether his endorsement proves a net asset or liability in individual districts. The key resolution point will be the November 2026 election results, when winning percentages for endorsed candidates in competitive races will become clear.

  • Track record of Musk's prior political endorsements and their success rate in 2022-2024 elections
  • Definition and scope of "Elon-backed" — whether this includes direct financial support, public endorsements, or both
  • Composition of candidate pool — geographic distribution, incumbency status, and competitiveness of their districts
  • Net favorability of Musk association in target swing districts and whether it mobilizes or alienates voters
  • Turnout patterns and broader midterm environment in 2026 relative to presidential election years

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (4% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
