The most searched question about the September 16 FOMC meeting has the least suspenseful answer on the board. A 25-basis-point cut trades at about half a cent on Kalshi, a zero-bid market whose last trade was a single penny, and at just under a cent on Polymarket as of August 18, 2026. Round both up generously and you get 1%. That is the whole answer, and it has barely moved all summer. What has moved, violently, is the other side of the board: the quarter-point hike that led Kalshi's market at 52 cents after the July meeting now trades at 28.5, and a plain hold has climbed to 70.5. The September story was never really about a cut. The real question is whether the hawks who forced a 9-3 vote in July can win the room, and only two scheduled chances remain for the Fed itself to speak before the decision. One of the three venues quoting this meeting is also priced a few points away from the other two, and it is probably not the one you would guess. We will get to that gap, because it is the closest thing this board has to a tradeable disagreement.
The Quick Answer
As of August 18, 2026, markets give a September rate cut about a 1% chance at most: the cut contract's midpoint sits near half a cent on Kalshi and just under a cent on Polymarket, with a hold at about 70.5 cents and a quarter-point hike at 28.5 on both exchanges. The real argument is hold versus hike, and fed funds futures price that hike a few points higher than the exchanges do. The full three-venue board, the two Fed set-pieces that can still move it, and when the first cut actually gets priced in are all below.
The September Board: Kalshi Vs Polymarket Vs CME FedWatch
All exchange prices below are bid-ask midpoints as of August 18, 2026, quoted in cents; a contract pays $1.00 if its outcome happens. CME FedWatch derives its probabilities from 30-day fed funds futures, and its snapshot here is August 17.
| September 16 Outcome | Kalshi (Aug 18) | Polymarket (Aug 18) | CME FedWatch (Aug 17) |
|---|---|---|---|
| Hold At 3.50%-3.75% | 70.5¢ | 70.5¢ | 69.4% |
| Hike 25bps | 28.5¢ | 28.5¢ | ~30.6% |
| Hike More Than 25bps | 0.5¢ | 0.35¢ | — |
| Cut 25bps | 0.5¢ | 0.95¢ | — |
| Cut More Than 25bps | 0.5¢ | 0.35¢ | — |
The row worth staring at is the hike. Two venues with completely different user bases, order books, and fee schedules landed on the same half-cent, 28.5, and this is real two-sided volume rather than a ghost town quote: Polymarket's September event alone has done about $36.9 million in volume. When two independent crowds agree that precisely, the number is the market's honest opinion. The cut rows are the opposite kind of signal. A cent on one venue and just under a cent on the other is the price of "the world would have to change first," and both boards sum to within a cent of 100, so there is no fat overround hiding value in the longshots either. If contract mechanics are new to you, our explainer on how prediction markets work covers the plumbing, and Kalshi's fee schedule explains why a 1-cent contract costs more than a cent to actually trade.
Why A Cut Trades At A Cent
Because six weeks ago the argument inside the building was about hiking. On July 29 the FOMC held the federal funds target range at 3.50%-3.75% for a fifth consecutive meeting, and the vote was 9-3. Beth Hammack, Neel Kashkari, and Lorie Logan each preferred a quarter-point hike, the most same-direction dissents at a Fed meeting since September 2016. A committee where a third of the voters want to raise rates does not pivot to cutting them six weeks later, and the market never seriously entertained it.
The honest case for a cut is not crazy, which is exactly why it is worth pricing rather than ignoring. The August 7 jobs report printed a 23,000 payroll decline for July, the unemployment rate held at 4.1%, and earlier months were revised down hard. Five days later the August 12 CPI report came in cool: headline prices rose 0.1% in July, 3.4% over the year, with core at 0.2% monthly and 2.5% annually, down from 2.6%. But look at what those two prints actually did to the board. The hike collapsed from 52 cents to 28.5. The cut went from about a cent to about a cent. Soft data spent three weeks killing the hike trade, and none of that selling built a cut position, because the same statement that carried three hike dissents also called inflation elevated. The data softened the hawks' case. It did not write the doves one.
The Gap Worth Watching: Futures Are Pricing More Hike Than The Exchanges
Here is that disagreement promised up top. The split is not Kalshi versus Polymarket; those two match to the half-cent. The split is the exchanges versus the futures market. CME FedWatch, which reads probabilities out of fed funds futures, showed 69.4% for a hold as of August 17, implying roughly 30.6% for the hike. A separate futures-based monitor, Investing.com's rate tracker, read the same meeting at 64.7% hold and 35.3% hike on the evening of August 18. The event-contract exchanges say 28.5.
Two to seven points, depending on which futures snapshot you use, is not an arbitrage headline, but on a two-outcome question it is a meaningful spread between real-money venues, and one of them has to be closer to the truth. The exchanges update tick by tick around the clock and visibly repriced through the jobs and CPI releases, so calling them stale is hard. Futures-implied numbers, on the other hand, absorb hedging flows from institutions that are not expressing a clean opinion on the meeting; some of that 35% is insurance, not forecast. The cleanest read is that the exchange crowd has already finished digesting August's data while some of the futures-implied hike premium is still draining out. Wednesday's minutes are the first event that can settle who is right, which brings us to the calendar.
Two Dates Left: The Minutes And Warsh At Jackson Hole
The July FOMC minutes drop Wednesday, August 19 at 2:00 p.m. Eastern. The statement already told us the vote was 9-3; the minutes tell us how loud the room was. If Hammack, Kashkari, and Logan were arguing from a broad base of sympathy, with several non-dissenting members close to joining, that 28.5-cent hike is cheap. If the minutes read like three voices against a settled majority, the hold grinds toward 80 and the futures premium drains.
Then comes the bigger one. The Kansas City Fed's Jackson Hole symposium runs August 27-29, and Kevin Warsh delivers the Friday-morning keynote on August 28, his first as Fed chair since taking office on May 22, 2026. One date worth pinning down: the symposium sits at the back end of August, not the week of the 20th, so it lands after the minutes, not before them. Warsh told reporters in late July that his remarks would lean toward longer-term structural questions rather than near-term guidance, but he has also made a point of saying the Fed will act independently of what markets are pricing. That posture is precisely why the speech matters. This Fed has stopped telegraphing between meetings, so a set-piece speech from the chair is the single richest scheduled signal left before September 16. The only data of consequence after that: the August jobs report on September 4 and the August CPI print on September 11, the last two releases the committee sees before it votes.
When Does The First Cut Actually Get Priced In?
If September is a cent, the natural follow-up is when the cut stops being a longshot, and the ladder markets answer it directly.
| Next-Move Market (As Of Aug 18) | Price |
|---|---|
| Polymarket: First Cut By The October Meeting | 4.4¢ |
| Polymarket: First Cut By The December Meeting | 13.5¢ |
| Kalshi: Next Hike By December 31, 2026 | 53.5¢ |
| Kalshi: Next Hike By June 30, 2027 | 69.5¢ |
The number I keep coming back to is that 53.5 sitting on top of the 13.5. Both prices describe the same four months of Fed meetings, and together they say the next move in 2026, if there is one, is roughly four times likelier to be a hike than a cut. Anyone searching "fed rate cut odds" is, per the market, about a year early: the cut conversation is a 2027 conversation, and the 2026 conversation is whether three dissents become seven votes. That is also why our price-blind AI panel's read on this meeting, which called the hike overpriced back when it traded at 52, lives on its own page: the standing Fed decision Model Verdict re-runs every cycle and grades itself in public, and the closely linked CPI market breakdown tracks the inflation prints that keep deciding this fight. For the wider context on how these venues price macro questions, our guides to Kalshi's economic markets and how Kalshi and Polymarket differ on settlement are the deeper reads, and the recession odds board is where the doves' real argument would show up first.
The Bottom Line
Here is the honest way to hold all of this at once. The hold at 70.5 is the market's base case, but it is not a settled one, and the next two weeks tell you which way it breaks. If Wednesday's minutes show sympathy for the dissenters beyond their three votes, the 28.5-cent hike was cheap and the futures crowd was right to price it hotter. If the minutes read like three voices against a settled majority and Warsh spends August 28 on structural questions rather than near-term policy, the hold grinds toward 80, the futures premium drains, and the cut conversation formally becomes a 2027 conversation, exactly where the ladder markets already put it. One honesty note about this site: OddsShopper's odds tools cover sports markets, not Fed contracts, so this page pitches no tool. Kalshi and Polymarket list CFTC-regulated event contracts, open to users 18 and older, with availability that varies by state as of August 2026, and the two platforms' state lists differ from each other. And if you want markets that settle faster than a Fed meeting while everyone waits on Warsh, our experts post free picks every day.
FAQ
What Are The Odds Of A Fed Rate Cut In September 2026?
About 1% at most. As of August 18, 2026, the 25-basis-point cut contract for the September 16 meeting sat at a half-cent midpoint on Kalshi (zero bid, 1-cent ask) and just under a cent on Polymarket, with the deeper-cut contracts at about half a cent or less. A plain hold traded at about 70.5 cents on both exchanges.
Could The Fed Hike Rates In September 2026 Instead?
That is the live question. As of August 18, a quarter-point hike traded at about 28.5 cents on both Kalshi and Polymarket, down from 52 cents on Kalshi right after the July meeting, when three FOMC members dissented in favor of a hike. Fed funds futures priced the hike a few points higher, roughly 31% to 35% depending on the snapshot.
When Are The July 2026 FOMC Minutes Released?
Wednesday, August 19, 2026 at 2:00 p.m. Eastern. They cover the July 28-29 meeting, where the committee voted 9-3 to hold the federal funds target range at 3.50%-3.75%, with Beth Hammack, Neel Kashkari, and Lorie Logan each preferring a quarter-point hike.
When Is The Jackson Hole Symposium In 2026, And Who Speaks?
The Kansas City Fed's symposium runs August 27-29, 2026, and Fed Chair Kevin Warsh delivers the keynote on Friday morning, August 28. It is his first Jackson Hole speech as chair, and because the Warsh Fed does not telegraph its intentions between meetings, it is the last scheduled moment before September 16 where the chair himself can move the board.
Will The Fed Cut Rates At All In 2026?
The market prices it as a clear underdog. As of August 18, Polymarket's ladder put a first cut by the October meeting at about 4.4 cents and by the December meeting at about 13.5 cents, while Kalshi priced a hike by December 31 at about 53.5 cents. In other words, if the Fed moves at all in 2026, the market says that move is roughly four times likelier to be a hike than a cut.
Is Trading These Markets The Same As Sports Betting?
No. Kalshi and Polymarket list CFTC-regulated event contracts, which are a different legal category from sportsbook betting. They are open to users 18 and older, availability varies by state as of August 2026, and the two platforms' state restrictions differ from each other. Check each platform's own eligibility rules.
