Markets put two-in-three odds on a 2026 Fed rate hike

Polymarket 66%
record: CMSIG2026082802 | category: momentum-repricing | target: CM-EVT-87QV1G78C4 | published: 2026-08-28
4-bullet brief | narrative
  • The Polymarket contract prices a 2026 Fed rate hike at 66%, reflecting majority-but-not-certain consensus.
  • Warsh's explicit hike signaling is consistent with the 66% pricing, though markets are not treating a hike as a done deal.
  • The companion Kalshi contract on rate hikes sits at 68%, showing tight cross-venue agreement and no meaningful arbitrage gap.
  • Both contracts resolve via official Federal Reserve rate decisions; a September hike announcement would likely push both toward full pricing.
