Analysis
This probability reflects market expectations for U.S. nominal GDP to reach a specific threshold in 2026. The 52% probability suggests roughly even odds, indicating significant uncertainty about whether nominal growth will exceed current market consensus levels. The main drivers are near-term inflation dynamics and real economic growth rates. Q2 2026 GDP data, which will be released by the Bureau of Economic Analysis in late May or early June, serves as the critical upcoming data point to resolve this uncertainty. The extremely low pricing on contracts betting for nominal growth above 2.5% in Q2 2026 (3¢) versus modest pricing on 1.5% growth (23¢) indicates markets view sustained higher nominal growth as unlikely in the near term, though full-year figures may differ from quarterly snapshots.
- ›Q2 2026 BEA advance GDP report will provide the first official quarterly nominal growth data, directly informing whether thresholds are met
- ›Core inflation readings throughout April and May will influence expectations for price growth component of nominal GDP
- ›Federal Reserve policy stance and any signaled rate changes affect both inflation expectations and real growth prospects
- ›Corporate earnings and labor market data in May-June will shape forecasts for nominal growth acceleration or deceleration
- ›Comparisons to 2025 baseline nominal GDP levels will determine whether 2026 targets require acceleration versus continuation of existing trends

Inflation 'Above 4%' Probability Crashes 21¢ as Oil Collapse Changes Inflation Outlook
The 'how high will inflation get in 2026: above 4%' contract collapsed -21¢ to 30¢ in a single session, making it one of the largest single-day moves in the recession/inflation cluster. The move appears directly connected to today's 7% oil price crash, which significantly reduces near-term inflation pressure.
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.
