Bracket families

2 clusters across 11 contracts.

These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.

Heads-up — heterogeneous clusters

The top two clusters share only 0% of their title tokens — “What price” vs “Will Karoline Leavitt leaves White House Press Secretary in before 2027”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This prediction reflects a 33% probability that SOFR (the Secured Overnight Financing Rate) will reach a specific threshold in April 2026. The forecast is based on expectations about Federal Reserve monetary policy and economic conditions over the coming months. SOFR could rise if inflation remains elevated, forcing the Fed to maintain higher rates longer than currently expected, or fall if the economy weakens and the Fed cuts rates. Conversely, a stronger economic backdrop or faster disinflation could push rates lower. The key uncertainty centers on the Fed's policy decisions in late 2025 and early 2026—particularly whether rate cuts continue as currently anticipated or pause due to inflation persistence. The December 2025 and March 2026 Fed meetings will provide critical signals about the rate environment heading into April.

  • Current SOFR trading levels and Fed funds futures prices as of June 2026 versus the April target level
  • Inflation data releases between now and April 2026, especially CPI and PCE readings that signal whether disinflation is on track
  • Fed meeting outcomes and forward guidance in December 2025 and March 2026, which will shape rate expectations
  • Market pricing divergence: Polymarket contracts average 33% vs. Kalshi's 31%, suggesting modest disagreement on probability despite small sample size
  • Historical volatility of SOFR around Fed policy announcements and the gap between current market expectations and the April threshold being tested

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.
