88% — the median of 6 frontier models, resolving by 2026-11-04.

Answer

Gemini (Google): 92% — The Fed almost never surprises markets on decision day when pricing heavily favors a pause following an active prior cycle. FOMC meetings with market consensus over 85% for a pause historically deviate less than 5% of the time on decision day. A move would require an unprecedented intraday communication reversal by Powell, as blackout period messaging held steady. The 8% risk reflects unexpected emergency tightening or dissenting blocs forcing an immediate 25 bps hike.

Answer

Claude (Anthropic): 5% — Context implies a September rate increase, which is highly implausible given actual 2025-26 Fed easing trajectory, suggesting a scenario mismatch that undermines confidence. The premise of a September rate increase contradicts the known Fed trajectory of cuts through 2025 into 2026, raising doubt about the scenario's internal consistency. If the September move was indeed a hike, markets expecting a pause would need no major shock between late September and October 28 to materialize for a hold to be… Given the apparent inconsistency in the setup, I weight this low since the premise itself seems factually off, reducing confidence the stated outcome tracks reality.

Answer

GPT (OpenAI): 84% — An immediate reversal after September’s hike would require a sharp deterioration in inflation, labor data, or markets. The FOMC announces today; absent an intermeeting emergency, the Committee need only maintain its September target range. Historically, the Fed often pauses at the meeting immediately after a hike, especially when markets are priced for no move. A surprise inflation print, payroll collapse, or acute financial-market stress before the statement would be the main reason to change course.

Answer

Grok (xAI): 87% — FOMC hold today after the September hike, matching market pricing. Announcement is this afternoon; only a last-minute data shock or dissent surge would produce a move. Post-hike holds are the modal outcome unless inflation or labor data re-accelerate, which markets say has not happened. A surprise September CPI or payrolls print would be the one thing that would reverse this.

Answer

DeepSeek (DeepSeek): 88% — The Fed almost never reverses a hike at the very next meeting, so this turns on whether an off-cycle shock forces an emergency move before Oct. 28. Since 1994 the FOMC has reversed a rate change at the immediately following meeting only in crisis episodes (2001, 2007-08, 2020), a base rate near 5-8%. The decision is already made at the Oct. 27-28 meeting; no data or speaker between now and the 2pm statement can alter the vote. A September hike with markets pricing no change implies the Committee signaled a pause; a surprise intermeeting cut would require a severe funding or labor-market…

Answer

Qwen (Alibaba): 94% — Markets already price no change on decision day itself; surprise FOMC moves against consensus are rare. Fed just hiked in September; pausing at the next meeting is the modal pattern historically (~80%+ of post-hike meetings). Market pricing on the day of the meeting is the strongest single predictor; surprises against it occur roughly 5-8% of the time. A surprise would require a sudden data shock or emergency between now and the 2pm release, leaving almost no window.
