The question of whether the Federal Reserve will increase interest rates by 25 basis points after its December 2026 meeting has captured significant attention on Polymarket, with trading volume reaching nearly $5 million. This market is crucial for investors and businesses, as the Fed's interest rate decisions profoundly influence borrowing costs, market liquidity, and the broader economic trajectory. The market's current odds strongly favor a hike, reflecting a widespread expectation that the central bank will continue its efforts to combat persistent inflation.

Recent Developments Point to Continued Tightening

The Federal Reserve's monetary policy has been under intense scrutiny amidst a landscape of elevated inflation and a resilient labor market. After raising the federal funds rate to a target range of 3.75%-4.00% in September 2026—the first hike in three years—the Federal Open Market Committee (FOMC) opted to hold rates steady at its October 28 meeting. However, this pause was widely seen as a temporary measure to assess the impact of previous tightening, rather than a definitive end to the hiking cycle.

Recent economic data has bolstered the case for further tightening. The October 2026 jobs report delivered a significant upside surprise, with the U.S. economy adding 165,000 nonfarm payroll jobs, nearly tripling Wall Street's forecasts. The unemployment rate also edged down to 4.1%, and average hourly earnings increased by 0.4% for the month and 3.1% annually. This robust labor market, coupled with inflation that remains above the Fed's 2% target, suggests that the central bank still has work to do.

Inflation, as measured by the Personal Consumption Expenditures (PCE) price index, rose 3.6% between September 2025 and September 2026. While core inflation showed some quarterly moderation, consumer inflation expectations for the year ahead increased to 3.9% in September 2026, the highest level since May 2023. The International Monetary Fund (IMF) projects U.S. headline inflation to reach 3.6% in 2026, with core inflation not expected to return to the Fed's 2% target until mid-2028.

Market Odds and Expert Consensus Align

On Polymarket, the "Yes" outcome for a 25 bps rate increase is currently priced at 0.785, implying a 78.5% probability of a hike. This strong conviction is echoed across other prediction platforms and by financial analysts. CME FedWatch, a widely referenced tool, forecasts a nearly 78% chance of the federal funds rate increasing to 4.00%-4.25% at the December meeting. Similarly, Kalshi shows an 80% probability for a 25 bps hike.

Expert opinions overwhelmingly support this view. A Reuters poll conducted in mid-October 2026 revealed that 100 out of 100 economists surveyed anticipate a December rate hike. Major financial institutions like UBS Wealth Management and Bank of America have also publicly stated their expectation for a December increase. ING is forecasting a 25 basis point hike, bringing the target rate to 4.00%-4.25%.

The Federal Reserve's own projections, as outlined in the September 2026 Summary of Economic Projections (SEP), indicate a "higher for longer" stance. Sixteen out of nineteen FOMC members projected at least one more rate hike by the end of 2026. Fed Chair Kevin Warsh has indicated that tighter financial conditions are having the desired effect, but the persistent inflation and strong jobs market suggest more action may be needed.

Outlook for the December Meeting

The FOMC's next meeting is scheduled for December 8-9, 2026. Ahead of this crucial decision, the November CPI report (due November 10) will provide further insights into inflationary pressures, which policymakers will almost certainly consider.

The confluence of a robust labor market, stubbornly high inflation, and a clear signal from the Fed's own projections and committee members has created a strong market consensus. While unexpected global events or a sudden deterioration in economic data could alter the outlook, the current evidence overwhelmingly suggests that a 25 basis point interest rate increase in December 2026 is a highly probable outcome.
