52% — the median of 6 frontier models, resolving by 2026-12-20.

Answer

Gemini (Google): 42% — The MPC remains divided, making an immediate cut or hike conditional on upcoming wage and services CPI prints. The 9-member MPC meets next in early November, typically favoring quarter-point adjustments only when quarterly forecasts align. Services inflation and pay growth remain stickier than expected, tilting a narrow majority toward holding rather than moving. A sharper-than-projected drop in September headline CPI below the 2% target would immediately flip the baseline to a cut.

Answer

Claude (Anthropic): 50% — Hinges on UK inflation and wage data trends into the next MPC meeting after the September hold. BoE just held rates while flagging that inflation pressures could force action, signaling a close, data-dependent call. MPC meetings often see splits when guidance is this explicit, and historically about half of 'warning' holds lead to a move within one or two meetings. Watch UK CPI, wage growth, and services inflation prints released before the next meeting for the deciding signal.

Answer

GPT (OpenAI): 54% — It turns on whether autumn inflation and wage data force the MPC to move rather than wait for clearer disinflation. The nine-member MPC can change Bank Rate at its next scheduled decision, likely in early November, by a simple majority. Historically the MPC often holds across consecutive meetings, but explicit concern over persistent inflation makes a move more plausible than baseline. A sharp fall in September–October CPI and pay growth would most likely convert a prospective hike or cut into another hold.

Answer

Grok (xAI): 62% — Whether Oct inflation data forces the Nov MPC to follow through on its own warning. Next scheduled MPC is 5 Nov 2026, six weeks after the Sep hold that already flagged possible further action. Recent-cycle change rate is ~35% of meetings; the explicit warning lifts this case above that base. A sub-2% Oct CPI print would most reverse the odds toward another hold.

Answer

DeepSeek (DeepSeek): 22% — Whether UK inflation and wage data between now and the MPC's next vote break the 2% target enough to force a cut or hike. The MPC's next scheduled meeting is 5 November 2026; a change requires a majority of the nine-member committee to shift from the current hold stance. Base rate: the BoE has held at 4% since August 2025, and historically the MPC moves at roughly one in three meetings when inflation is near target. The August 2026 CPI print (due 16 September) and wage growth data are the key triggers; a surprise above 3.5% would most change my mind toward a hike.

Answer

Qwen (Alibaba): 62% — BoE's next meeting is likely in early November; persistent inflation warning language signals intent to act. BoE MPC meetings are roughly every 6 weeks; next scheduled meeting after Sep 21 is likely early November 2026, giving ~6 weeks to act. The context says the BoE 'warned persistent inflation pressures may require further policy adjustments,' which is forward guidance language that historically precedes… Base rate for a BoE rate change at any given meeting is ~30-35%, but explicit forward guidance about 'further adjustments' raises this substantially; a hold would…
