  • 2026-09-03T00:00:00.000Z momentum-repricing
    Fed hold in September stays near fully priced Kalshi ladder
    • Kalshi ladder prices the September 2026 Fed funds upper bound in the 3.50-3.75% range, with 99% above 3.50% but only 2% above 3.75%.
    • Fed Governor Christopher Waller's hold signal is fully consistent with this pricing; the market already implied a pause before his remarks.
    • Kalshi at 99% above 2.75% shows no credible tail for aggressive cuts back toward pre-2025 levels.
    • A longer-horizon ladder (CM-EVT-MR57HVWJT3) prices 72% above 3.75% and 31% above 4.00%, suggesting the market sees meaningful odds of a hike at a later meeting.
  • 2026-09-02T12:29:56+00:00 volume-spike
    Traders back rates staying above 3.50% after the Fed 98% · $212K 24h
    • Kalshi prices a 98% chance the fed funds upper bound holds above 3.50% post-meeting, leaving almost no room for a cut.
    • 24h volume of $212K is 87% of the contract's entire all-time handle, a near-record single-day flush.
    • With a Fed decision imminent, traders are locking in the no-cut view at extreme conviction levels.
    • Contract resolves on the rate announced at the next FOMC meeting.
  • 2026-08-28T00:00:00.000Z momentum-repricing
    Fed funds upper bound seen near 3.75 to 4 percent Kalshi ladder
    • Kalshi ladder prices the Fed funds upper bound in the 3.75-4.0% range: 50% above 3.75% but only 1% above 4.0%.
    • Warsh's focus on inflation over employment suggests the market-implied rate near 3.75-4.0% could shift higher if price data stays elevated.
    • The sharp drop from 50% at 3.75% to 1% at 4.0% shows the market treats 4.0% as a tail outcome despite Warsh's hawkish rhetoric.
    • Combined with the 68% Polymarket hike probability, the ladder implies the expected hike would land the rate in the 3.75-4.0% zone, not above.
  • 2026-08-28T00:00:00.000Z momentum-repricing
    Fed funds upper bound seen near 3.75% after Jackson Hole Kalshi ladder
    • Kalshi ladder prices the federal funds upper bound in the 3.50-3.75% range: 98% above 3.50%, but only 47% above 3.75%, with trading volume up over 1,100x day over day.
    • Warsh's price-first messaging at Jackson Hole is consistent with the ladder's sharp break above 3.75%, where probability collapses to 2%.
    • The volume surge signals Warsh's speech is drawing intense fresh attention to the near-term rate path.
    • The Kalshi contract resolves via Federal Reserve official rate decisions; any September hike would shift the upper bound and reprice the full ladder.
  • 2026-08-26T00:00:00.000Z momentum-repricing
    Fed funds near 3.5 percent after next meeting, market holds Kalshi ladder
    • Kalshi ladder prices 99% odds the upper bound stays above 3.5%, but only 32% above 3.75%, implying consensus at 3.5-3.75%.
    • Unchanged July PCE inflation at 3.7% and unrevised Q2 GDP of 1.5% support the market's hold-rate pricing.
    • A companion Kalshi ladder for a later meeting (CM-EVT-MR57HVWJT3) prices 53% above 3.75% and 17% above 4.0%, signaling modest tightening risk in the outer months.
    • Resolves via the Federal Reserve's official federal funds rate announcement following the relevant FOMC meeting.
