Tracks the leading outcome in a winner-take-all prediction market set with 5 outcomes.

Why this matters:
Markets are pricing an 87% likelihood that inflation will exceed 3.6% for the year ending April 2026, with related contracts suggesting meaningful probability mass around 4%+ thresholds. This high probability reflects current economic conditions where price pressures remain elevated relative to the Federal Reserve's 2% target. The assessment depends critically on incoming CPI data over the next several months and Fed policy decisions. Core inflation readings above 2.5% are priced at 92¢, indicating broad-based price growth is expected. Key drivers include energy prices, labor market tightness, monetary policy persistence, and consumer spending patterns. The May 2026 CPI release for April data will be a major checkpoint for resolving whether inflation remains entrenched above historical norms or begins subsiding toward target.

Key factors:
- Year-to-date CPI data as of May 2026 shows cumulative inflation trajectory relative to 3.6-4.5% annualized thresholds
- Federal Reserve policy stance and recent interest rate decisions, which influence near-term inflation dynamics through 2026
- Core CPI running above 2.5% (priced at 92¢) suggests services and non-energy inflation remain sticky
- Energy and commodity price movements, which directly affect headline CPI readings in the April-April measurement window
- Labor market conditions and wage growth rates, which influence pricing power and consumer demand through mid-2026

## 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.
