Will the Fed increase interest rates by 25 bps after the September 2026 meeting?

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.

Executive summary

Agents61 74% vs market 87.5% (gap -13.5%) on “Will the Fed increase interest rates by 25 bps after the September 2026 meeting?”. Medium confidence; resolution risk Medium.

Why the market may be wrong

  • Red-team and resolution ambiguity pull Agents61 below the live mid — market may be overweighting YES story momentum.
  • Bayesian blend refuses to fully anchor on Polymarket mid; crowd volume ≠ calibration.
  • Macro: path of policy, growth, and inflation prints matter more than vibes.

Why the market may be right

  • Live mid 87.5% is backed by $38.6M volume — informed flow may already be priced.
  • YES mid 87.5% with $38.6M notional. Crowded tape ≠ calibrated probability; thin books exaggerate gaps. Use mid as a prior, not a truth.
  • If settlement rules match the headline question tightly, crowd calibration is more trustworthy.

Bull / YES evidence

  • Market still assigns 87.5% to YES with $38.6M volume — the path is considered live.
  • Macro: path of policy, growth, and inflation prints matter more than vibes.
  • Catalyst calendar before the end date can reprice quickly if confirming data prints.

Bear / NO evidence

  • Kill-shots: (1) resolution text does not match the intuitive question, (2) data used is stale vs end date, (3) narrative double-counts the same catalyst already in the mid.
  • Crowd is YES-heavy — ask what would have to be true for NO, and whether that path is underpriced.
  • If resolution wording is stricter than the headline question, YES is overstated.

Key catalysts

  • · Official data / decisions before Sep 16, 2026
  • · Major headline that changes the settlement-relevant fact pattern
  • · Liquidity shock on Polymarket that moves mid without new information

Invalidation conditions

  • Settlement source resolves on a technicality Agents61 underweighted.
  • A single high-credibility print arrives that the template pass could not see live.
  • Market mid was already incorporating private or faster information.

Tail paths & model risk

Model risk: template/LLM research can sound calibrated while missing a settlement edge case. Position risk is out of scope (no trading). Treat Probability Gap as a research prompt, not a bet size.
