Analysis

This 8% probability indicates traders assess a low likelihood that core CPI year-over-year inflation will be exactly at a specific target level in August 2026. The recent data points show core inflation readings around 2.2-2.8%, suggesting the market expects continued moderation or stability in core price pressures. Key factors influencing this assessment include the Federal Reserve's monetary policy stance, wage growth trends, and supply-chain conditions. The August 2026 CPI release, scheduled for early September 2026, will definitively resolve this contract. Until then, traders are weighing the path of inflation over the coming months against the specific price target embedded in this contract. The low probability reflects either market consensus around a different inflation outcome, or uncertainty about which exact level core CPI will reach.

  • Core inflation readings in April and June 2026 ranged 2.2-2.8%, establishing the recent trend traders are extrapolating forward
  • The Federal Reserve's interest rate decisions and forward guidance between now and August will influence whether inflation accelerates, stabilizes, or declines further
  • Wage growth data and labor market conditions directly impact service-sector inflation, a major component of core CPI
  • Supply-chain disruptions or commodity price movements could shift inflation expectations before the August data release
  • The specific price target of this contract may not align with market consensus on the most likely outcome, explaining the low 8% probability

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.
