Will the Fed Cut or Raise Rates in September 2026? Here’s What Markets Expect
The Federal Reserve’s September meeting has suddenly become one of the biggest events on the U.S. economic calendar, with investors now facing an unusual question: will the Fed cut rates, leave them unchanged, or raise them?
The answer looked considerably clearer earlier this month. But a sharp shift in inflation concerns, higher oil prices and comments from Federal Reserve Chair Kevin Warsh have pushed expectations toward a possible rate hike.
As of August 31, financial markets were pricing in roughly a 57% probability of a September rate increase, according to CME-linked market pricing cited by Reuters. That is a major change from earlier in August, when expectations had tilted toward the Fed keeping rates unchanged.
For prediction-market traders, the September decision has therefore become a particularly interesting market to watch.
What is the Fed expected to do in September?
The Federal Open Market Committee is scheduled to meet on September 15–16, 2026, with the policy decision due on September 16.
The Fed currently has its federal funds target range at 3.50% to 3.75%, after leaving rates unchanged at its July meeting.
That means the September meeting could produce one of three outcomes:
Rate hike: The target range moves higher.
Rate hold: Rates remain at 3.50%-3.75%.
Rate cut: The Fed lowers the target range.
The most important question for markets right now is whether recent inflation pressure will outweigh signs of weakness in the labor market.
Why have rate-hike expectations jumped?
One of the biggest catalysts has been Kevin Warsh's recent comments on inflation.
Following his speech at the Jackson Hole economic symposium, investors became more concerned that the Fed may need to tighten monetary policy rather than begin easing it. Reuters reported that the probability of a September hike rose sharply, with market pricing moving from around 35% to nearly 56% after Warsh's remarks.
By August 31, Reuters reported that markets were pricing the probability of a September hike at about 57%.
That is a significant shift because markets had recently been leaning toward a September hold.
Inflation remains the key problem
The Fed's challenge is that inflation has not disappeared, while the labor market has shown signs of losing momentum.
A July inflation report gave the case for a rate increase some additional support, with Reuters reporting that expectations for a hike gained momentum following the data.
At the same time, weaker employment data have complicated the picture. Earlier in August, rate futures reduced the probability of a September hike after softer jobs data, while economists remained divided about whether tighter policy was still necessary.
That leaves the Fed balancing two competing risks:
Inflation staying too high could require tighter monetary policy.
A weakening labor market could argue for keeping rates unchanged or eventually cutting them.
The jobs report could change everything
Investors are now watching the upcoming U.S. employment data particularly closely.
The latest reporting suggests markets expect only modest job growth in August, with the unemployment rate expected to remain around 4.1%. The data could therefore have a major influence on expectations before the September FOMC decision.
A surprisingly strong jobs report could strengthen the case for a rate hike if it comes alongside persistent inflation.
A weak employment report, however, could revive expectations that the Fed will hold rates steady or eventually begin cutting.
What are prediction markets saying?
This is where the September Fed decision becomes particularly interesting for Predict My Market users.
Prediction markets allow traders to express their expectations about future economic events rather than simply reading analyst forecasts.
The broader 2026 Fed-rate market has already shown how quickly expectations can change. Polymarket's rate-cut market previously reflected strong expectations for zero cuts in 2026 after the July meeting, when the Fed maintained its 3.50%-3.75% target range.
But the latest shift toward a possible September hike shows why the market can move rapidly when new inflation, employment or Fed-policy information arrives.
What could happen to stocks and bonds?
A September rate hike would likely be interpreted as a more hawkish signal from the Federal Reserve.
Higher rates can put pressure on growth-oriented stocks, increase borrowing costs and push Treasury yields higher. Financial markets have already reacted to the changing expectations: Reuters reported that U.S. Treasury yields jumped as investors increased their bets on a September hike.
Technology and other rate-sensitive stocks could therefore be particularly sensitive to the decision.
On the other hand, a surprise hold or cut could produce a different market reaction, especially if investors interpret it as evidence that the Fed is becoming more concerned about employment and economic growth.
The prediction-market question
For Predict My Market, the central question is straightforward:
Will the Federal Reserve raise interest rates at its September 2026 meeting?
The market will ultimately depend on the official FOMC decision rather than analyst forecasts or media commentary.
The September decision is scheduled for September 16, 2026, making the coming weeks especially important for traders watching inflation, employment, oil prices and Federal Reserve communication.
For now, the market has moved decisively toward the possibility of a hike—but the next round of U.S. economic data could still change the odds before policymakers meet.
