Analysis

Market participants are assigning a 93% probability that average U.S. gasoline prices will exceed $4.40 per gallon by year-end 2026, based on 20 contracts trading on Kalshi. This reflects expectations that fuel costs will remain elevated through December rather than falling sharply. The forecast depends primarily on crude oil supply dynamics, OPEC production decisions, and global demand trends, particularly from China and other major economies. Near-term catalysts include upcoming energy inventory reports, geopolitical developments affecting Middle Eastern production, and macroeconomic data signaling recession risk or demand destruction. Notably, the market assigns only a 6% probability to prices falling below $2.00, suggesting traders view extreme downside scenarios as unlikely.

  • Current WTI crude oil price and trend—crude typically drives 50-70% of retail gasoline variation
  • OPEC+ production policy decisions, particularly Saudi Arabia's output levels and stated production targets through Q4 2026
  • U.S. refinery capacity utilization rates and seasonal maintenance schedules that affect gasoline supply
  • Macroeconomic growth expectations and vehicle fuel demand projections relative to inventory levels
  • Geopolitical risk premiums from Middle Eastern tensions, sanctions, or supply disruptions that could compress margins

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.
