Fed rate hike by 2026?

Platform comparison

Market context

The Federal Reserve will hold its December 2025 meeting on 16–17 December, with the decision announcement scheduled for 18 December. This market resolves affirmatively only if the Fed raises its target federal funds rate during that specific window—a scenario currently priced at zero probability across major prediction platforms. The upper bound of the target range would need to move upward from its current level; emergency hikes are included in the resolution criteria, though no mechanism currently exists to trigger such action outside the scheduled FOMC calendar.

The 0% implied probability reflects the Fed's established trajectory since mid-2024, when rate cuts commenced. The central bank has reduced rates by 100 basis points across four consecutive meetings, with the federal funds rate now sitting in the 4.25–4.50% range as of November 2025. Historical precedent matters here: the Fed has not reversed course mid-easing cycle without a major economic shock or financial stability threat. Kalshi and Polymarket both display this market at near-zero odds, though Betfair's decimal format (1.01–1.02) and Smarkets' commission structure produce marginally different effective prices for traders seeking minuscule YES exposure.

The December meeting occurs against a backdrop of stable inflation readings and labour market softness. Traders monitoring this contract should track any unexpected economic data releases between now and mid-December—particularly the Consumer Price Index (12 December) and initial jobless claims—alongside any Fed communications signalling a policy reversal. The probability remains anchored at zero because rate hikes require either a sharp inflation reacceleration or explicit Fed guidance shift, neither of which current market consensus anticipates within the next six weeks.
