Traders push October Fed hold odds to 66% on Polymarket
Polymarket pricing now favors a Federal Reserve pause at the October 27–28 meeting: 66% odds of no change versus 34% for a 25-basis-point hike. This reverses last week’s balance when a hike held about 67%.
Repricing occurred in two steps on September 30. Hold odds rose 28 percentage points in 24 hours to 58.5% as hike odds fell 27 points. After the August PCE report that same day, the hold lead widened to 66%. Bitcoin trades near $84,116, up 1.3% over 24 hours. The market shift puts a hold ahead but does not indicate a change in Federal Reserve policy.

Why odds shifted toward a hold
August PCE inflation came in softer than expected: headline PCE rose 3.4% year over year versus a 3.7% forecast; core PCE printed 3.0% versus 3.3%. July’s headline and core PCE were revised down by 30 basis points each.
Fed Decision in October? Polymarket
The October Polymarket contract has nearly $20 million in volume. Market pricing concentrates on a hold versus a single 25-basis-point hike. The current target range is 3.75%–4.00%. Inflation data and hike odds remain linked as traders reassess after each release. These probabilities are market prices rather than official forecasts or commitments.
Is a December hike still likely?

Markets price a delay: Polymarket’s December contract implies a 74% chance of a 25-basis-point hike. A separate market shows an 82% chance of another rate hike in 2026 and a 97% chance of no rate cuts this year. August CPI at 3.4%, elevated price pressures in PMI components, resilient labor data, and hawkish Fed communication support the prospect of further tightening.
Bond market expectations align: Polymarket assigns a 91% chance that the 10-year Treasury yield reaches 5.3% before 2027 and a 64% chance it hits 5.4%. Upcoming data before October 28, including the September jobs report, could shift odds again. Strong labor or inflation prints could revive hike bets; weaker readings could reinforce a hold.

An October hold would avoid an immediate tightening of financial conditions. A delayed hike keeps restrictive policy in place. Rates and financial conditions influence risk appetite but do not solely determine Bitcoin’s direction. The key variable is upcoming macro data and whether it confirms a pause or reignites tightening expectations. Traders should treat Polymarket odds as one indicator of macro expectations rather than evidence of a Fed commitment.
