6% — the median of 6 frontier models, resolving by 2026-12-20.

Answer

Gemini (Google): 4% — The Fed is firmly in an easing or neutral holding regime, making rate hikes virtually unprecedented in this phase of the cycle. FOMC dots and recent communication prioritize downside labor risks over premature inflation flare-ups requiring immediate tightening. A pivot from pauses/cuts to rate hikes within a single inter-meeting cycle historically requires an extreme, sudden inflation shock. A massive upside print in both core PCE and nonfarm payrolls before the November FOMC would be required to revive rate hike odds.

Answer

Claude (Anthropic): 3% — Fed is in a cutting cycle amid labor market softening; a hike would require an inflation shock reversal. Fed cut rates in Sept 2025 and dot plots signaled further cuts through 2026, not hikes. Base rate for a hike right after a cutting cycle began is very low absent a major inflation surprise. Only a sharp unexpected inflation spike or wage/price spiral would flip this toward a hike.

Answer

GPT (OpenAI): 7% — It turns on whether inflation or labor data deteriorate enough to reverse the Fed’s likely hold/cut bias by November. The next scheduled FOMC decision is Nov. 3-4, 2026, leaving only September and October jobs and inflation reports to shift policy. After a restrictive-rate cycle, consecutive additional hikes are uncommon unless inflation reaccelerates materially or expectations become unanchored. A sharp upside surprise in core PCE/CPI or wage growth before the October data cutoff would raise this estimate substantially.

Answer

Grok (xAI): 28% — Whether Oct data show inflation reaccelerating enough to force a November hike. Next FOMC is ~4-5 Nov 2026; they need Sept/Oct CPI, PCE and jobs prints before deciding. Late-cycle hike base rate at a given meeting is 15-25%; residual post-Sept uncertainty puts this a bit above. A hot September CPI would most raise the odds; otherwise they hold.

Answer

DeepSeek (DeepSeek): 12% — The Fed only hikes if inflation data between now and the next meeting re-accelerates sharply; the bar is high. The FOMC's next meeting is Nov. 3-4, 2026, and the committee has signaled a wait-and-see stance after the September hold. Core PCE and CPI prints due mid-October would need to surprise well above 3% to force a hike, but recent trend has been disinflationary. Base rate for hikes immediately after a hold with no new shock is low; the 2019 and 2024 precedents show the Fed stays put absent a clear inflation break.

Answer

Qwen (Alibaba): 3% — The Fed is in a cutting cycle; a hike would require an inflation shock no one currently forecasts. The Fed cut rates in Sept 2025 and markets price further easing into 2026; a hike would be a complete policy reversal. Core PCE has been trending toward 2%, and labor markets have cooled—no plausible near-term trigger for tightening. Only a sudden commodity or tariff-driven inflation spike before the Oct/Dec meeting could change this, and none is on the horizon.
