This event group tracks whether the Federal Reserve will change interest rates at its October 27-28, 2026 meeting, and by how much. Both Polymarket and Opinion platforms offer identical outcome brackets: 50+ bps decrease, 25 bps decrease, no change, 25 bps increase, and 50+ bps increase. Resolution depends on the official FOMC statement and the change in the upper bound of the target federal funds rate.
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both platforms employ identical resolution logic tied to the same official FOMC announcement and use the same rounding rule (up to nearest 25 bps) and fallback (no change if no statement by next meeting).Primary resolution logic: Federal Reserve official website (https://www.federalreserve.gov/monetarypolicy/openmarket.htm) and FOMC statement after October 27-28, 2026 meeting per official Federal Reserve calendar (https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm)Core resolution logic:
- Determine the upper bound of the target federal funds rate prior to the October 27-28, 2026 FOMC meeting
- Identify the new upper bound announced in the FOMC statement after the meeting
- Calculate the basis point change (new level minus prior level)
- Round fractional changes up to the nearest 25 bps bracket (e.g., 12.5 bps rounds to 25 bps)
- Match the rounded change to one of five outcomes: 50+ bps decrease, 25 bps decrease, no change, 25 bps increase, or 50+ bps increase
- If no FOMC statement is released by the end of the next scheduled FOMC meeting, resolve to 'No change'
Edge cases & clarifications:
- Fractional basis point changes: Any change not evenly divisible by 25 bps is rounded up to the nearest 25 bps bracket. For example, a 12.5 bps cut resolves as 25 bps decrease; a 37.5 bps increase resolves as 50+ bps increase.
- No statement by next meeting: If the FOMC fails to issue a statement by the end of the next scheduled FOMC meeting following October 2026, the market resolves to 'No change'.
- Exact 50 bps boundary: A change of exactly 50 bps increase or decrease resolves to the '50+ bps' bracket, not the 25 bps bracket.
Polymarket
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 October 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 October 27-28, 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 October 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.
Opinion
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 September 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 September 15-16, 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 September 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.
Frequently asked questions
Prediction markets like this one often diverge from traditional analyst surveys because they embed real financial incentives—traders profit or lose based on accuracy, whereas survey respondents face no direct cost for being wrong. Market odds reflect live, aggregated bets rather than point-in-time expert opinion. This market's pricing can shift rapidly as economic data, inflation reports, or Fed communications emerge. Many traders use both sources together: prediction markets for dynamic, incentivized consensus and analyst forecasts for detailed reasoning and longer-term scenarios.
Polymarket and Opinion may show different odds due to variations in liquidity, user base composition, and fee structures. Polymarket and Opinion can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Traders on one platform may have different risk appetites, time horizons, or access to information flows, causing prices to diverge temporarily. Arbitrage traders often exploit these gaps, but friction costs and platform-specific rules can prevent instant convergence. Monitoring both venues gives you a fuller picture of market uncertainty and helps identify potential mispricings.
This market resolves around Oct 28, 2026, once the Federal Reserve's October 2026 policy decision is announced and verified. The outcome is confirmed through credible public reporting of the Fed's official statement and any rate changes. Resolution hinges on the specific action taken—whether rates are cut, held, or raised, and by how much. Traders should monitor the Fed's calendar and economic releases leading up to the announcement, as inflation data, employment figures, and forward guidance can all influence the final decision.
Key catalysts include monthly inflation reports (CPI and PCE), employment data, GDP growth figures, and any Fed communications or speeches by policymakers. Unexpected economic shocks—financial stress, geopolitical events, or commodity price swings—can rapidly shift rate-cut expectations. Market volatility and yield curve movements often precede major repricing in this market. Traders should track the Fed's forward guidance and watch for shifts in market-implied rate expectations, which tend to lead prediction market adjustments by hours or days.
