18% — the median of 6 frontier models, resolving by 2026-11-05.

Answer

Gemini (Google): 18% — Hikes into softening labor data require severe inflation surprises that rarely materialize inside a three-week window. The FOMC historically pauses when employment weakens unless core PCE exceeds the committee's expectation by over 30 bps. September CPI and payroll releases before October 27 offer very little runway to establish an alarming re-acceleration trend. A sharp rebound in core services inflation prints above 0.4% MoM would be required to shift the consensus toward hiking.

Answer

Claude (Anthropic): 2% — Fed is in a cutting cycle with labor market softening; a rate hike is a sharp policy reversal unlikely by Oct 2026. Fed has been cutting through 2025 amid labor market softness, and no clear inflation resurgence narrative dominates current data. A reversal to a hike within one meeting cycle would require a major inflation shock; nothing in the described context suggests that. Base rate for a single-meeting hike after a sustained cutting cycle is very low absent a surprise CPI/PCE spike or wage shock.

Answer

GPT (OpenAI): 18% — It turns on whether inflation reaccelerates enough to outweigh a cooling labor market before the October decision. The FOMC would need clear upside inflation or expectations data before October 27–28, while the next CPI arrives October 14. Late-cycle Fed moves are usually pauses or cuts when jobs soften; a hike after weaker employment is an exception. A hot September CPI or renewed inflation-expectations rise would materially increase the odds of an October hike.

Answer

Grok (xAI): 28% — Whether incoming CPI/PCE and payrolls reverse the recent jobs softness enough for a 2026 hiking cycle to resume. FOMC must vote a hike on Oct 28; only three weeks of data remain, with Sept CPI (Oct 15) and Oct payrolls (Nov 7, too late) as the last prints. Base rate of a hike at any given meeting outside an active tightening cycle is ~8-12%; this sits modestly above because inflation has not yet fallen to target. A 0.3pp+ upside surprise in core CPI would most shift odds; otherwise the Committee is likely to hold given labor-market cooling.

Answer

DeepSeek (DeepSeek): 12% — A hike needs a hot CPI print and a still-tight labor market; neither is in evidence three weeks out. The FOMC's own September dot plot and Powell's 'data dependent' framing point to a hold unless inflation reaccelerates sharply. September CPI lands October 13 and the October jobs report October 2 already showed softening; a hike would need both to surprise hot. Base rate for a hike at a meeting with no prior signal is under 10%; this case sits slightly above only because inflation remains above 2%.

Answer

Qwen (Alibaba): 18% — Fed is more likely to pause or cut than hike given the labor-market softening described in the context. The context explicitly flags softer jobs data as the dominant signal; since mid-2024 the Fed has been in an easing cycle, not a tightening one. A hike requires inflation to re-accelerate sharply enough to override labor weakness within three weeks—no such surprise has been reported. If October CPI (due ~Oct 13) prints well above consensus, that single data point would be the main catalyst to revise this upward.
