Tracks the leading outcome in a winner-take-all prediction market set with 20 outcomes.

Why this matters:
This market estimates a 96% probability that core PCE inflation will be positive (above 0.0%) in September 2026. The high probability reflects historical precedent: core inflation has remained positive through most recent economic cycles, making a deflationary outcome relatively unlikely. The main factors driving this assessment are the Federal Reserve's inflation-targeting framework, labor market conditions, and wage growth trends. Markets are pricing in meaningful probability only for higher inflation thresholds—41 cents for above 0.3%—suggesting traders expect modest rather than elevated inflation. The critical data point will be the PCE report release for September 2026, expected in early October, which will definitively resolve all related contracts. Until then, economic data releases throughout summer 2026, including employment reports and consumer spending indicators, will likely influence market expectations.

Key factors:
- Core PCE has remained above 0.0% annualized in all months since 2021 except during deflationary episodes, establishing a strong historical baseline
- The 96% probability implies a roughly 4% market-implied probability of deflation, which typically requires severe economic contraction or demand collapse
- Probability drops to 77% for above 0.2% and 41% for above 0.3%, indicating markets expect core PCE in the 0.0-0.3% range rather than higher levels
- Labor market tightness and wage growth dynamics will be primary drivers of whether September inflation meets or falls short of the 0.0% threshold
- The September 2026 PCE report, released in early October 2026, will provide the definitive settlement data

## 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.
