Liquidity has increased across venues: Polymarket’s global market has traded about $148.5 million since May 13 launch; Kalshi’s market shows about $68.2 million. Combined volume exceeds $215 million, up from $192.6 million reported over the weekend.
The repricing sets the stage for the Sept. 15–16 FOMC meeting, concluding Wednesday with the policy statement, Chair Kevin Warsh’s press conference, and an updated Summary of Economic Projections with a new dot plot.
Inflation Data and Market Repricing
BREAKING: The odds of a September interest rate hike surge to 79% after US CPI inflation hits 3.4% in August.
It is incredible to think that, at the start of 2026, markets were expecting the Fed’s 3rd interest rate CUT of the year this month.

— The Kobeissi Letter (@KobeissiLetter) September 11, 2026
Headline CPI: +0.4% month over month in August after +0.1% in July; 12-month rate 3.4%, unchanged and in line with consensus. Core CPI: +0.3% month over month versus +0.2% forecast; annual core eased to 2.4% from 2.5%, lowest since March 2021, matching estimates.
Energy drove the headline: gasoline +3.9% month over month after −2.9% in July, +27.4% year over year; energy index +2.1% month over month, +16.3% year over year; fuel oil +52% year over year. Shelter +0.3% month over month with annual shelter easing to 3.0% from 3.2%. Food +0.1%. Airline fares +2.7%, communication +2.3%, education +0.8%, used cars and trucks +0.4%. Natural gas −1.1% and electricity −0.2%.
Economists characterized the print as tilting hawkish due to the monthly core uptick and energy dynamics. Nationwide’s Kathy Bostjancic cited risk of energy pass-through and inflation expectations, shifting to a quarter-point hike call.
Rate Path and Tools
The federal funds target range has been 3.50%–3.75% throughout 2026. A 25 bps increase would move it to 3.75%–4.00%, the first hike since July 2023. The September meeting became “live” in late August: odds moved from ~25% in mid-August to near 50% after Warsh’s Aug. 28 Jackson Hole remarks emphasizing a fixed 2% PCE target and citing 12-month PCE at 3.7% and six-month at 4.1%. A stronger-than-expected August payrolls report at 162,000, with July revised from −23,000 to +21,000, and PPI at +0.4% month over month and 5.4% year over year on Sept. 10, supported higher odds.
Target Rate Probabilities for 16 Sep 2026 Fed Meeting CMEgroup
CME FedWatch has priced higher odds than prediction markets, sitting in the mid-80s after the CPI print. Venue spreads have persisted. August PCE will be published after the meeting, so the committee votes without it.
Implications for Crypto and Markets
Bitcoin Price Chart Coingecko
Markets are assessing potential effects on Bitcoin, Ether, DeFi borrowing costs, and stablecoin yields. Higher expected rates generally strengthen the dollar and short-term Treasury yields, conditions associated with pressure on liquidity-sensitive assets. The clearest reaction has appeared in bonds: the 2-year Treasury yield reached its highest level since late July after Warsh’s remarks. No documented, comparable move in crypto prices or liquidations has been reported around the speech or CPI release.
Prediction market odds function as sentiment and price-discovery signals and may shift before Wednesday’s decision.
