Prediction Markets & Fed Policy: An Accuracy Analysis
Evidence from Federal Reserve Rate Decision Markets
EXECUTIVE SUMMARY
Overview
Prediction markets have emerged as a powerful and underutilized data source for investment professionals. Unlike traditional surveys or analyst forecasts, prediction markets aggregate the real-money views of a broad set of informed participants into a single, continuously updating probability signal.
This paper analyzes the accuracy and timeliness of Kalshi Federal Reserve interest rate decision markets across 24 FOMC meetings from May 2023 through March 2026. Our findings demonstrate that these markets provide highly reliable signals with meaningful predictive power beginning at least two to three weeks before each decision — well ahead of the typical market-moving window that most investment frameworks assume.
Key findings
- 95.7% directional accuracy on decision day across all 24 meetings analyzed
- The market predicted the correct outcome in 23 of 24 cases
- The sole miss — September 2024's 50bps cut — remained genuinely ambiguous until the final 48 hours
- Confidence of 80%+ achieved by 30 days before the decision on average
- Rises to ~90% inside 14 days, and ~95%+ inside 7 days
- Provides actionable signal well ahead of blackout periods and traditional event risk windows
- Meetings where the market had 90%+ confidence were correct every time
- Only in truly ambiguous situations (like Sep 2024) did probability fail to converge
- The data is available in real-time, daily, and at low cost relative to the investment edge it provides
For investment managers active in rates, fixed income, or macro strategies, this data offers an informational advantage: the ability to quantify, track, and act on a probabilistic view of Fed policy with a degree of accuracy that rivals or exceeds most traditional research products.
SECTION 1
Background: Prediction Markets and Fed Policy
1.1 What are prediction markets?
Prediction markets are financial exchanges where participants trade contracts tied to the outcome of real-world events. Prices — which range from $0 to $1 — represent the collective market-implied probability of an event occurring. A contract trading at $0.72 implies the market assigns a 72% probability to that outcome.
Unlike opinion polls or analyst surveys, prediction markets require participants to put capital at risk, which creates strong incentives for accuracy. The structure is simple: if your prediction is correct, you profit; if wrong, you lose. This mechanism has been shown repeatedly in academic literature to outperform other forecasting methods, particularly in political and macroeconomic domains.
Kalshi, a regulated prediction market exchange, offers contracts on Federal Reserve rate decisions for each FOMC meeting. Five possible outcomes are traded simultaneously: Cut 50bps, Cut 25bps, Hold, Hike 25bps, and Hike 50bps. Together, these prices must sum approximately to 100%, ensuring internal consistency.
1.2 Why Fed rate decisions matter for investors
The Federal Reserve's interest rate decisions are among the most consequential macro events for financial markets. They directly affect:
- Fixed income pricing and duration risk across the entire yield curve
- Equity valuations, particularly for rate-sensitive sectors such as financials, real estate, and utilities
- Currency markets, as rate differentials drive capital flows between countries
- Credit spreads and the cost of corporate borrowing
1.3 Dataset overview
This analysis covers all 24 FOMC meetings between May 2023 and March 2026. The dataset spans a rich variety of policy regimes:
- A rate-hiking cycle concluding in 2023 (two hikes covered)
- An extended hold period through much of 2023 and 2024 (12 meetings)
- An easing cycle beginning September 2024, including one surprise 50bps cut and multiple 25bps cuts
- A return to holding in 2025–2026 as the policy cycle stabilized

Accuracy Analysis
2.1 Overall directional accuracy
The headline result is striking: Kalshi prediction markets correctly identified the actual FOMC decision in 23 of the 24 meetings analyzed — a 95.7% directional accuracy rate on decision day itself. The sole miss was the September 18, 2024 meeting, at which the Fed surprised markets with a 50bps cut when consensus had firmly coalesced around 25bps.
Beyond simply getting the direction right, the markets also conveyed high confidence in their correct calls. On decision day, the average implied probability assigned to the outcome that actually occurred was 95.1%.
2.2 How confidence builds over time
A critical investment question is not just whether the market is accurate, but how early it becomes so. Three distinct phases are visible across the 24-meeting dataset:
60–30 DAYS
Implied probability rises from ~68% to ~80%, with directional accuracy already in the 90–95% range. While confidence is moderate, the market is typically pointing in the correct direction even this far in advance.
30–14 DAYS
Confidence builds meaningfully, crossing 85% by two weeks before the meeting. This is the period where positioning based on prediction market data becomes increasingly actionable.
14–0 DAYS
The final two weeks see a sharp convergence toward the actual outcome. Average confidence reaches ~90% at 14 days, ~91% at 7 days, and ~95% on decision day.
2.3 Accuracy by time horizon
Accuracy remains consistently high at all measured horizons, suggesting the market rarely pointed in the wrong direction even many weeks out. The key differentiator is confidence: investors using this data 7–14 days before a decision can act on an ~90% implied probability signal that has historically been correct in virtually every instance.

| Mar 18, 2026 | Hold | ✓ | 92% | 97% | 98% | 99% |
The Hold meetings of 2023–2024 were predicted with near-certainty throughout (90–99% confidence at all horizons), reflecting a clear and consistent Fed communication strategy. The cutting cycle of late 2024 and 2025 saw somewhat lower but still high confidence, given genuine uncertainty about the pace of easing.
SECTION 4
The September 2024 Exception: Anatomy of a Surprise
4.1 What happened
On September 18, 2024, the Federal Reserve cut its benchmark rate by 50 basis points — a larger-than-expected move that caught markets off guard. Prediction markets, like most other forecasting tools, failed to lock in this outcome. It stands as the only incorrect call in the 24-meeting dataset.
4.2 What the data shows
DAYS 45–50
The market was genuinely split, with Cut 50bps briefly leading on some days, reflecting early positioning ahead of a widely anticipated easing cycle.
DAYS 15–35
Cut 25bps consolidated a strong lead, reaching 80–85% implied probability. Most participants had converged on 25bps as the base case.
DAYS 0–3
Leaked reports and Fed communication drove Cut 50bps briefly above 50% in the final 48–72 hours. But on decision morning, Cut 25bps flipped back to 63% before the announcement.
4.3 Investment implications
Low-confidence signals should be heeded: When the market cannot converge above 70% on any single outcome by the week before the meeting, that itself is actionable information — it signals genuine policy uncertainty that warrants hedging or position reduction.
The signal was not silent: Even though the market ultimately called the outcome incorrectly, Cut 50bps never fell below 10–15% implied probability. An investor monitoring this data would have known a 50bps cut was a live possibility at all times — and could have sized positions accordingly.
In conventional risk management terms, the September 2024 meeting was not a "black swan" for prediction market users — it was a known-unknown, with a clearly communicated tail probability throughout the entire pre-meeting window.

Investment Applications
5.1 Strategies directly informed by this data
RATES POSITIONING & FIXED INCOME DURATION
Portfolio managers can use prediction market probabilities to dynamically adjust duration risk ahead of FOMC decisions. When the market is pricing 90%+ probability of a hold, extending duration carries minimal event risk. When probabilities are split, a neutral or hedged positioning is warranted.
OPTIONS & DERIVATIVES STRATEGIES
Implied probability data can be compared directly against swaption or rate cap/floor pricing to identify mispricings. When prediction markets assign 85% probability to hold but options markets price in more uncertainty, there may be a profitable trade in selling rate volatility.
EQUITY SECTOR ROTATION
Rate-sensitive equity sectors (banks, REITs, utilities, growth stocks) can be rotated in advance of expected policy moves. With 90%+ confidence signals available 7–14 days before decisions, managers have sufficient lead time to adjust sector weights.
RISK MANAGEMENT & PORTFOLIO HEDGING
Prediction market probabilities provide a clean, quantifiable input to pre-meeting VaR adjustments and stress tests. Risk managers can set position limits and hedge ratios directly from probability data rather than relying on qualitative Fed-watching.
5.2 Limitations and caveats
- The dataset spans a single policy instrument (Fed Funds rate) for the U.S. Federal Reserve. Generalization to other central banks should be done with caution.
- The 2023–2026 period was characterized by relatively clear Fed communication policy. Future periods of genuine ambiguity may reduce accuracy.
- Prediction market liquidity varies — prices may be less reliable for the most extreme outcomes which rarely trade with high volume.
- Correlation with other market signals (CME FedWatch, OIS pricing) should be monitored to assess the diversification value of the signal.
SECTION 6
Conclusion
The evidence presented in this paper makes a compelling case for incorporating prediction market data into the investment process for any strategy with exposure to Federal Reserve policy risk.
Across 24 consecutive FOMC meetings, Kalshi prediction markets achieved 95.7% directional accuracy with an average confidence of 95% on decision day. That confidence built steadily over the weeks before each meeting, providing actionable signals 14–30 days in advance with 80–90% reliability.
The lone miss — September 2024 — was not a failure of the prediction market mechanism. It was a genuinely ambiguous decision that confused all market participants, and even in that case the market clearly communicated uncertainty and kept the eventual outcome visible as a tail risk.
Bottom line: Prediction markets correctly called 23 of 24 Fed decisions, with ~90% confidence available 7–14 days before each announcement. For investors managing rate-sensitive exposures, this represents a high-quality, data-driven edge that is available today.
