The Federal Reserve raises the target federal funds rate by the completion of its October 2026 meeting.

Question

Six frontier AI models put this at 6% by 9 Dec 2026. The market says 100%. Full reasoning from every model.

WillHappen.ai · Accepted Answer

6% — the median of 6 frontier models, resolving by 2026-12-09.

Answer

Gemini (Google): 4% — The Fed is firmly in an easing cycle, making a sudden pivot to rate hikes before November 2026 extraordinarily improbable. FOMC dots and futures project steady rate cuts or holds through 2026, not rate increases, amid cooling labor and inflation trends. Only an unprecedented, severe re-acceleration of CPI inflation above 4% would force Powell's FOMC to hike in this timeframe. With less than two months until the resolution window closes, the Fed has zero meetings teed up for a rate increase.

Answer

Claude (Anthropic): 5% — Fed has been cutting in this cycle; a hike by Oct 2026 would require a sharp inflation resurgence and policy reversal. As of today (Sep 2026) the Fed's trajectory has been rate cuts, not hikes, making a reversal within one meeting cycle unlikely. A hike would require a sudden inflation shock and FOMC consensus shift, which historically takes many months of data before action. Base rate for a full policy direction reversal within ~1 month is very low absent a specific inflation surprise already visible in data.

Answer

GPT (OpenAI): 18% — It turns on whether inflation reaccelerates enough by October to overcome the FOMC’s likely preference to hold or ease. The FOMC itself must raise the upper bound at a scheduled meeting by late October 2026; no outside approval is needed. In comparable late-cycle settings, hikes after a restrictive plateau are uncommon unless inflation expectations or activity data worsen materially. A sustained CPI/PCE upside surprise and firmer labor data before the September or October meetings would most raise the odds.

Answer

Grok (xAI): 8% — No hike since Dec 2025; remaining Sept/Oct meetings need a surprise inflation surge. Policy stayed on hold or eased through Sep 2026 with inflation near target. Two leftover FOMC dates leave little time; mid-cycle reversals after a pause are rare (~10%). A CPI print above 3.5% would be the main thing that could flip the call.

Answer

DeepSeek (DeepSeek): 3% — A hike requires the Fed to reverse its easing cycle within six weeks, with only the Oct 27-28 meeting left to act. The FOMC has been cutting, not hiking, through 2025-26; a hike needs a fresh inflation shock plus a consensus shift among 12 voters. Only one meeting remains in the window (Oct 27-28, 2026), so the entire outcome hinges on a single two-day decision. Base rate for a hike in a cutting regime within one meeting is very low; 2023-24 pauses produced zero hikes after the last cut.

Answer

Qwen (Alibaba): 7% — The Fed has not hiked mid-cycle since 2023; a hike requires inflation to re-accelerate sharply while growth stays firm. The Fed cut rates through late 2024 and held in 2025; no FOMC member's dot or public guidance suggests a hike is being contemplated. A hike would require CPI to re-accelerate well above 3% persistently, which has not happened since mid-2023 and would need a major supply shock. Base rate of mid-cycle reversals from easing to tightening within ~13 months is historically very low; only 1998-99 and 2022-23 come close, both driven by clear shocks.
