18% — the median of 6 frontier models, resolving by 2027-05-11.

Answer

Gemini (Google): 27% — Sustained UK growth reaching 2.2% hinges on whether projected rate cuts unlock robust productivity and consumption over 2026. Bank of England central projections frequently skew optimistic two years out, while UK potential trend growth is only 1.2-1.5%. ONS initial first estimates for Q4 2026 due February 2027 rarely exceed 2.0% year-on-year without extraordinary fiscal stimulus. A sharper-than-expected rebound in private real wage growth and business investment would be required to shift odds above 40%.

Answer

Claude (Anthropic): 3% — This likely conflates quarterly with annualized/annual growth; actual quarter-on-quarter UK GDP rarely nears 2.2%. UK quarter-on-quarter GDP growth has been in the 0.1-0.6% range for years, with 2.2% QoQ essentially unprecedented outside pandemic rebounds. BoE 'upgraded to 2.2%' almost certainly refers to annualized or annual GDP growth projection, not single-quarter QoQ growth. ONS Q4 2026 release (due Feb 2027) would need to show an extraordinary and historically unmatched quarterly jump for this to resolve yes.

Answer

GPT (OpenAI): 29% — It hinges on whether the Bank’s 2.2% forecast is met rather than revised down before the ONS flash estimate. The ONS must publish an initial Q4 estimate by 11 May 2027, after December output and full-quarter data are collected. Forecasts exactly at a threshold convert poorly: quarterly GDP estimates are volatile and first releases are often revised. Odds would rise sharply if October-November activity data show broad-based growth near the pace needed for the BoE projection.

Answer

Grok (xAI): 2% — UK q/q GDP hitting 2.2% requires a COVID-scale rebound that current data and policy cannot produce. ONS first Q4 estimate lands mid-Feb 2027; BoE’s 2.2% figure, if literal, sits far above any non-rebound quarter in 70 years. Typical UK q/q growth is 0.1-0.5%; only 2020-21 rebounds exceeded 2%, and no analogous shutdown/reopening is underway. A surprise fiscal blast or data revision could move the needle, but neither is priced or legislated as of mid-November.

Answer

DeepSeek (DeepSeek): 8% — A single quarter hitting 2.2% annualised is a tail event; the BoE's own upgrade is a forecast, not a base rate. ONS initial Q4 releases are noisy and often revised; a 2.2% quarterly print would be the strongest since 2021's reopening distortions. The BoE's 2.2% is a year-on-year or annualised projection, not a quarterly outturn, and MPC forecasts routinely miss by 1-2pp. The one thing that would change my mind is a November/December PMI surge plus a fiscal giveaway in the Autumn Budget.

Answer

Qwen (Alibaba): 48% — BoE central forecast sits exactly at the threshold, making this nearly a coin flip on forecast error symmetry. BoE MPR point estimate of 2.2% means the outcome must beat or match the modal forecast; historically BoE quarterly GDP errors are roughly symmetric with ~0.4pp standard… Initial ONS releases have shown a mild downward revision bias in recent years, slightly favoring the 'below' side of the distribution. A upside surprise to Q3 data or a fiscal stimulus announcement before year-end would push this above 55; a softening in services PMI or labor market data would push it…
