Fed funds upper bound prices in at 4.25 percent

Kalshi ladder
record: CMSIG2026092701 | category: momentum-repricing | target: CM-EVT-MR57HVWJT3 | published: 2026-09-27
4-bullet brief | narrative
  • Kalshi ladder prices the federal funds upper bound at 4.25%, with 52% odds above 4.25% but only 4% above 4.50%, implying market sees 4.25% as the likely ceiling.
  • Inflation and jobs-focused news flow is consistent with the ladder's near-50/50 split at 4.25%; the market is not yet committing to a further hike beyond that level.
  • Volume surged 82.5x day over day on this Kalshi contract, a strong signal fresh capital is positioning around the October FOMC decision.
  • The sharp drop from 52% at 4.25% to just 4% at 4.50% signals the market treats 4.50% as a tail scenario, not a base case, heading into key PCE and NFP prints.
