Kalshi prices a 25 basis-point Federal Reserve rate hike at the July 28–29, 2026 meeting at 10¢ — a 10% market-implied probability — while fed funds futures tracked by the CME FedWatch tool imply roughly 18.8%. Our blended estimate lands near 14%, a +4 percentage-point (pp) edge on the YES side at 10¢, with the June CPI print on July 14 as the trigger that makes or breaks it.
Kalshi’s contract “Will the Federal Reserve Hike rates by 25bps at their July 2026 meeting?” last traded at 10¢ on July 4, 2026, against a fed funds futures curve that puts the same outcome near 18.8% (CME FedWatch, July 3, 2026). That is one of the widest gaps between prediction markets and the futures strip anywhere on the 2026 macro board. This Deep Dive walks the math, steelmans the hold case, and sets out exactly what would flip the read.
The Bet at a Glance:
• Market: “Will the Federal Reserve Hike rates by 25bps at their July 2026 meeting?” (KXFEDDECISION-26JUL-H25) — Kalshi, July 4, 2026
• Price: 10¢ last trade (9¢ bid / 10¢ ask) = 10% implied probability — Kalshi order book, July 4, 2026, 06:00 UTC
• Cross-market: Polymarket prices the same hike at 9.6¢; “no change” at 89.5¢ — Polymarket, July 4, 2026
• Futures benchmark: ~18.8% hike-implied for July — CME FedWatch, July 3, 2026
• Our estimate: ~14% — blend of futures pricing and named-economist consensus (methodology below)
• Edge: +4pp on YES at 10¢ — modest, and honest about it
• Catalyst / date: June CPI on July 14, 2026; FOMC decision July 29, 2026 — Federal Reserve calendar
• Disconfirmation: a soft June core CPI print (≤0.2% month on month) kills the hike case — our model
Methodology: how we built the 14% estimate
Prediction-market prices in cents read directly as probabilities, so Kalshi’s 10¢ is a 10% market-implied probability before fees and spread. There is no sportsbook leg here, so no de-vig adjustment is needed; the futures benchmark comes from the CME FedWatch tool, which converts 30-day fed funds futures into meeting-by-meeting probabilities. Our independent estimate blends two anchors at equal weight: the futures-implied 18.8% (CME FedWatch, July 3, 2026) and a named-economist consensus we place near 9%, built from published July-specific calls by Bill Adams of Fifth Third, Greg Daco of EY-Parthenon, and Deutsche Bank’s house view that hikes arrive in September and December rather than July. The blend rounds to ~14%. Caveats: futures pricing can embed hedging premium that overstates tail outcomes, economist surveys lag fast-moving data, and one CPI print — due July 14 — can move both anchors several points in either direction. Treat the 14% as a corridor of roughly 11–17%, not a point estimate.
The market and the price: a 9pp gap to the futures strip
The Federal Open Market Committee (FOMC) meets on July 28–29, 2026, with the decision due July 29. At its June 17 meeting the Committee held the target range at 3.50%–3.75% on a unanimous 12–0 vote, and the statement kept the hawkish line that “inflation remains elevated relative to the Committee’s 2 percent goal, in part reflecting supply shocks that have driven price increases in certain sectors, including energy” (Federal Reserve, June 17, 2026).
On Kalshi’s July 2026 Fed decision market, the outcome ladder as of July 4, 2026 (06:00 UTC) reads: no change 90¢, hike 25bps 10¢, cut 25bps 1¢, hike of more than 25bps 1¢, cut of more than 25bps 1¢. Open interest on the two live contracts is deep for a macro market — roughly 2.5 million contracts on “no change” and 1.7 million on the 25bps hike. Polymarket’s “Fed Decision in July?” event agrees almost to the cent: no change 89.5¢, hike 25bps 9.6¢, on $37.9 million of lifetime volume and about $5.5 million of live liquidity. The two venues are efficient against each other; the anomaly is that both sit ~9pp below the CME FedWatch futures-implied ~18.8%.
Is the 25bps hike at 10¢ on Kalshi value? On the numbers, marginally yes — with real caveats. The market-implied probability is 10%; fed funds futures put the same outcome near 18.8% (CME FedWatch, July 3, 2026), and our blended estimate is ~14%, a +4pp edge on YES. The case rests on the June dot plot, where nine officials pencilled in at least one 2026 hike, and on a May inflation pulse — CPI at 4.2% year on year, core PCE at 3.4% — that is moving away from the 2% goal, not towards it. The case against is that no named Wall Street economist we can find forecasts a July move, and the Committee has been explicit that it wants the June CPI report (July 14) before judging whether the energy shock is bleeding into core prices. A 4pp edge on a thin-tail outcome is a lean, not a conviction play: it clears the noise threshold, barely, and only until July 14.

The case for the bet: the data has stopped cooperating with 10¢
The inputs behind our estimate all point the same direction: the tail is fatter than a dime.
Start with the inflation run-rate. The May CPI report showed prices rising 0.5% on the month and 4.2% year on year, the fastest annual pace in more than three years, with energy up 23.5% over 12 months on the back of the Middle East supply shock (CNBC, June 10, 2026). Then the Fed’s preferred gauge confirmed it: May headline Personal Consumption Expenditures (PCE) inflation printed 4.1%, up from 3.8% in April, and core PCE — the series the Committee actually steers by — rose to 3.4%, its highest since October 2023 (Yahoo Finance, June 25, 2026). Core acceleration is the number that converts an energy shock from “look through it” to “respond to it”.
Second, the Committee’s own projections. The June Summary of Economic Projections showed nine officials anticipating at least one hike in 2026 and six anticipating at least two — against nine expecting no move or a cut. A committee that split is one hot print away from a live July meeting, and there are only four scheduled meetings left this year to deliver the moves the hawkish half already forecasts. Capital Economics’ Thomas Ryan argues the data leaves the Fed with “little choice but to tighten policy amid strength in economic activity and the labor market” and pencils in three hikes; Deutsche Bank’s house call is two, starting in September. If the June CPI due July 14 prints hot — say core at 0.4% month on month or above — the September consensus drags forward fast, and a 10¢ contract does not stay at 10¢ while that repricing happens. That is the trade: it is not a bet that the hike is likely, it is a bet that 10% understates a genuinely two-sided meeting.
Third, the market microstructure. Prediction markets have lagged the futures strip on this question all year — the same venues priced near-zero hike risk in May when FedWatch already showed close to a one-in-three chance of a hike by December. When two markets disagree by 9pp, the one anchored by institutional rate desks has historically been the better guide at monetary-policy meetings.
The case against: nobody on the record forecasts a July move
Steelman the 90¢ side honestly and it is formidable. The single most important fact for the hold case: not one named economist at a major institution publicly forecasts a July 2026 hike. Deutsche Bank, among the most hawkish houses on the Street, expects the first hike in September precisely because the Committee wants more than one clean month of data. EY-Parthenon’s Greg Daco said after the May PCE release, “So I still anticipate that the Fed will hold tight for the time being, even though inflation is twice as high as its main target of 2%” (Yahoo Finance, June 25, 2026).
The June statement itself supports patience: the vote to hold was unanimous, with zero hawkish dissents — the classic precursor to a hike is at least one dissenting vote, and there was none. The energy-driven nature of the shock also argues for holding: central banks conventionally look through supply-side price spikes, and hiking into a Middle East disruption risks compounding a growth hit. Add the sample-size caveat on our own model — a 50/50 blend of two anchors is a judgment call, and if the futures leg is inflated by hedging premium (institutions paying up for protection against a hawkish surprise they do not actually expect), the true probability sits closer to the economists’ 9% than to 14%, and 10¢ is roughly fair. Variance matters too: this is a binary, news-driven contract three weeks from resolution, and one soft print marks it to 3–4¢ overnight.
“The Fed will be unhappy about inflation when they meet next in July, but likely will still hold rates steady.”

Where this bet breaks
The lean on the 25bps hike at 10¢ rests on assumptions that could fail. It breaks if ANY of these fire:
- June core CPI prints at or below 0.2% month on month on July 14. A soft core reading validates the “look through the energy shock” framing, freezes the hawkish dots until September, and marks the July hike contract towards 3–4¢. This is the single biggest trigger, and it lands more than two weeks before the meeting.
- Fed speakers close the July door in the July 10–18 window. If two or more voting members explicitly frame September as the earliest live meeting before the pre-meeting blackout begins on July 18, the market’s 10¢ becomes the ceiling, not the floor.
- Energy retraces hard. The 23.5% year-on-year energy surge is the engine of headline inflation. A sustained crude sell-off — the kind that follows a Middle East de-escalation — undercuts the entire hike narrative and drags core expectations with it.
- The price moves past 15¢. Above roughly 15¢ the gap to our 14% estimate is gone; the read is fully priced in. The edge exists only in the 9–13¢ window.
What to watch between now and July 29
The calendar does most of the work. June CPI lands Tuesday, July 14 at 8:30 a.m. ET — the question is whether core holds at the 0.3%-plus pace that has core PCE at three-year highs. June PPI follows July 16, and the University of Michigan July inflation-expectations final prints July 24. The FOMC blackout period runs from July 18, so any deliberate signalling from voters happens in the July 10–18 window; watch scheduled appearances by the 2026 voting rotation. On the market side, the tell is the spread between Kalshi/Polymarket and the futures strip: if FedWatch pushes above 25% post-CPI while the prediction markets sit under 15¢, the venue gap is confirming rather than closing — and that has historically resolved towards the futures. Decision day is Wednesday, July 29, 2026, 2:00 p.m. ET.
TL;DR
Kalshi prices a 25bps Fed hike at the July 28–29, 2026 meeting at 10¢ (10% implied); Polymarket says 9.6¢. Fed funds futures via CME FedWatch imply ~18.8%. Our blended estimate is ~14%, a +4pp edge on YES at 10¢ — a lean, not a conviction read, on a committee whose June dot plot showed nine officials forecasting at least one 2026 hike while core PCE sits at a three-year high of 3.4%. The whole read hinges on June CPI, July 14: core at 0.2% or softer kills it; 0.4% or hotter likely doubles the contract.
FAQ
What are the odds the Fed hikes rates in July 2026?
As of July 4, 2026, Kalshi prices a 25 basis-point hike at the July 28–29 FOMC meeting at 10¢ (a 10% implied probability) and “no change” at 90¢. Polymarket is nearly identical at 9.6¢ and 89.5¢. Fed funds futures tracked by CME FedWatch imply a higher ~18.8% hike probability. All prices are snapshots and move with every data release.
Is the 25bps hike at 10¢ on Kalshi value?
Our blended estimate puts the true probability near 14% against a 10¢ price — a +4pp edge, which is positive but thin. It is a small-edge lean that depends entirely on the June CPI report (July 14) keeping the hawkish half of the FOMC’s June dot plot live. Above roughly 15¢, the edge is gone.
Is Kalshi legit?
Yes. Kalshi is a federally regulated US derivatives exchange: it is a CFTC-designated contract market, and its event contracts — including the Fed decision series analysed here — trade on a regulated order book. That regulatory status is why its macro markets, alongside Polymarket’s, are increasingly quoted as probability benchmarks by analysts and media. Regulated does not mean risk-free: contracts can and do go to zero.
Do Kalshi and Polymarket agree on the July Fed decision?
Almost exactly. Kalshi shows 90¢ no change / 10¢ hike; Polymarket shows 89.5¢ / 9.6¢ (both July 4, 2026). The disagreement worth watching is not between the two venues but between both of them and the fed funds futures strip, which implies roughly twice their hike probability.
What would change the July Fed prediction?
The June CPI print on July 14 is the pivot. Core at 0.2% month on month or below entrenches a hold and the hike contract fades towards 3–4¢; core at 0.4% or above makes July genuinely live and the contract likely reprices above 20¢. Fed-speaker guidance before the July 18 blackout and a sharp move in energy prices are the secondary triggers.
