8% — the median of 6 frontier models, resolving by 2031-11-07.

Answer

Gemini (Google): 4% — Mandating a 32-hour workweek requires national legislation that business lobbies and centrist ruling coalitions strongly oppose. No G7 nation has lowered its statutory workweek below France's 35-hour threshold since 2000, setting a near-zero modern base rate. Current G7 governments face productivity deficits and aging workforces, pushing policy toward more hours worked rather than fewer. A left-wing sweep in France or the UK explicitly running on a 32-hour statutory cap is the only plausible path before 2031.

Answer

Claude (Anthropic): 2% — No G7 government has a serious legislative push toward a nationwide 32-hour standard workweek mandate. France's 35-hour week is the closest precedent but took decades and still allows overtime beyond it, far from a hard 32-hour cap. Pilot programs in UK, Japan, and elsewhere remain voluntary trials, not binding national legislation, and none are advancing toward mandates. Business lobbies and current center-right/center governments across G7 (US, Japan, Germany, UK, Italy) oppose mandatory cuts, making passage by 2031 very unlikely.

Answer

GPT (OpenAI): 27% — France, Japan or a future UK government would need to turn pilots and party support into a nationwide hours-cap law. France’s 35-hour statute shows G7-wide hours mandates are possible, but no G7 has cut its legal norm to 32 hours nationwide. Most four-day-week trials are voluntary or sectoral; a statutory cap must clear cabinet, parliament and employer opposition before 2030. A decisive shift would be a 2027–29 election delivering a governing majority pledged to a 32-hour legal standard, especially in France or the UK.

Answer

Grok (xAI): 12% — A left government in France or UK must pass a 32h statute after 2027 elections. France’s 35h law (2000) never tightened further; a 32h cut still needs new nationwide legislation by end-2030. UK Labour or equivalent would require a working majority plus union pressure, but fiscal and growth costs make it politically costly. No G7 has cut standard hours since 2000; only pilots exist, so the base rate is near zero and US/Japan/Italy/Germany sit even lower.

Answer

DeepSeek (DeepSeek): 12% — No G7 government has even a draft bill for a 32-hour statutory week; the clock is the binding constraint. Only national legislatures can mandate this, and none of the seven has a 32-hour bill past committee as of late 2026. Precedent is thin: France's 35-hour week (2000) is the closest G7 case, and it took years of cohabitation politics to pass. The likeliest trigger would be a left government in Spain or the UK making it a coalition price, but neither has scheduled such a vote before 2030.

Answer

Qwen (Alibaba): 4% — No G7 government has the political capital or coalition to legislate a 32-hour cap; even France's 35-hour law took a decade of buildup. France is the only plausible candidate (already at 35h), but Macron's reforms loosened rather than tightened hours, and no major party currently campaigns on 32h. The jump from voluntary 4-day-week pilots to binding nationwide legislation has no precedent in any advanced economy; employer opposition would trigger constitutional… A surprise left-wing landslide in France or Germany before 2029 would be the one development that could move this above 10%.
