Tracks the leading outcome in a winner-take-all prediction market set with 11 outcomes.

Why this matters:
This 81% probability indicates that prediction-market traders expect airline fares in the Consumer Price Index for urban consumers to exceed 304.0 in April 2026. The contract pricing reflects broader expectations about travel demand and fuel costs heading into spring. The primary driver appears to be seasonal airline pricing patterns, where spring and summer typically see elevated fares due to increased leisure travel demand. The resolution date is April 2026, meaning the outcome depends on actual CPI data released by the Bureau of Labor Statistics in early May 2026. The high probability suggests traders view airline fares exceeding this threshold as the base case, though the significant gap between the 61-cent top contract and 95-cent lower thresholds indicates some uncertainty about how far above 304.0 fares might climb. Factors that could shift this include fuel price volatility, airline capacity decisions, and changes in consumer travel patterns heading into the summer season.

Key factors:
- Seasonal airline pricing historically peaks in April-May, making elevated fares a typical outcome
- Jet fuel prices and global oil markets significantly influence airline pricing power and final fares
- The top contract (above 304.0) trades at 61¢ versus 95¢ for thresholds at 282-288, suggesting meaningful uncertainty about the upper bound
- Consumer travel demand in spring 2026 depends on economic conditions and employment trends in early 2026
- BLS will release April 2026 CPI airline fares data in early May 2026, definitively resolving this contract

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
