Fed October Decision Polymarket Odds: October Rate Hike Sits at 64%

Bitcoin and the wider cryptocurrency market are facing a renewed macroeconomic headwind as traders increasingly anticipate another Federal Reserve interest-rate hike in October. Fed October decision Polymarket odds are sitting at a 65% chance of a rate hike next month.

The latest shift in expectations follows comments from Federal Reserve Governor Michael Barr, who said further monetary tightening may be needed to bring inflation back toward the central bank’s 2% target.

At the same time, fresh economic data pointed to a U.S. economy that remains surprisingly resilient, with business activity and employment showing strength alongside persistent price pressures.

The result has been a significant repricing of expectations for the Fed’s October meeting, and that could have important consequences for Bitcoin and other risk assets.

Fed October Decision Polymarket Odds: Prediction Markets Put October Hike Chances at 65%

Prediction-market traders are currently assigning a 64% probability to a 25-basis-point Fed rate increase at the October 27-28 meeting, according to Polymarket, which is tracking the decision.

The market gives approximately 35% odds to no change, while the probabilities of either a larger hike or a rate cut remain below 1%. Polymarket’s market has generated more than $14M in trading volume, providing a sizeable pool of capital behind those expectations.

The figures have moved considerably as investors digest the latest inflation data and increasingly hawkish comments from Fed officials.

That makes the October meeting particularly important for cryptocurrency investors. A further increase would take the federal funds target range above its current 3.75%-4% level following the Fed’s September rate increase.

What Would Another Fed Hike Mean for Bitcoin?

For crypto investors, the biggest issue is liquidity. Bitcoin has increasingly traded as a macro-sensitive risk asset, meaning changes in interest-rate expectations can substantially affect demand for cryptocurrencies.

Higher rates can make cash and government bonds more attractive relative to speculative assets. They can also raise borrowing costs and reduce liquidity flowing into higher-risk investments.

Cryptocurrencies have nevertheless shown considerable resilience. Bitcoin surged above $86,000 earlier this month, reaching an eight-month high, despite the Fed already raising rates by 25 basis points in September. Recent gains have been supported by stronger ETF flows, improving regulatory sentiment and short covering.

Bitcoin was also on course for its first three-month winning streak from July through September since 2012, according to CoinDesk.

That resilience is significant because it suggests investors are not necessarily treating higher rates as an automatic reason to abandon crypto. However, the market reaction later in the week showed that monetary policy still matters.

Bitcoin finished September 25 around $84,071, retreating from its September 21 peak as Treasury yields rose and expectations for further Fed tightening grew. Ethereum followed a similar pattern, ending the week around $2,693.
