Fed Decision in December?

According to the latest prediction market data for the query “Fed Decision in December?”, traders have formed a strong consensus.

Currently, 25 bps increase is dominating the market with an overwhelming 76.5% chance of winning. No change follows in second place at 21.5%, while 25 bps decrease sits in third with 0.8%. The betting volume for this specific market has already reached $16.8M, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• 25 bps increase (76.5%): Currently commanding the highest probability, 25 bps increase is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 77¢, signaling a high degree of market conviction. This contract alone has generated $5.1M in volume.

🥈 Tier 2: The Primary Challengers

• No change (21.5%): Positioned as the most viable alternative, No change maintains a 21.5% chance of resolving true. Its “Buy Yes” shares currently trade at 22¢.
• 25 bps decrease (0.8%): Sitting in third place with a 0.8% probability, the market shows measured skepticism toward 25 bps decrease, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~1.2%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes 50+ bps decrease (0.7%), and 50+ bps increase (0.5%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like 50+ bps decrease are still attracting notable interest.

The FED interest rates are defined in this market by the upper bound of the target federal funds range. The decisions on the target federal funds range are made by the Federal Open Market Committee (FOMC) meetings.

This market will resolve to the amount of basis points the upper bound of the target federal funds rate is changed by versus the level it was prior to the Federal Reserve's December 2026 meeting.

If the target federal funds rate is changed to a level not expressed in the displayed options, the change will be rounded up to the nearest 25 and will resolve to the relevant bracket. (e.g. if there's a cut/increase of 12.5 bps it will be considered to be 25 bps)

The resolution source for this market is the FOMC’s statement after its meeting scheduled for December 8-9, 2026 according to the official calendar: https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm.

The level and change of the target federal funds rate is also published at the official website of the Federal Reserve at https://www.federalreserve.gov/monetarypolicy/openmarket.htm.

This market may resolve as soon as the FOMC’s statement for their December meeting with relevant data is issued. If no statement is released by the end date of the next scheduled meeting, this market will resolve to the "No change" bracket.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome 25 bps increase currently trades at 76.5%, but our AI places its Fair Value at just 60.9%. This creates a large negative EV Gap of -15.6%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies No change as the premium value opportunity on the board. While the market only assigns it a 21.5% trading probability, our AI’s Fair Value assessment sits at 25.4% — yielding an impressive +3.9% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include 50+ bps increase (EV Gap: +2%) and 25 bps decrease (EV Gap: +0.1%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
