Electric vehicles account for more than 50% of global new passenger car sales in a calendar year before 2035.

Question

Six frontier AI models put this at 62% by 26 Oct 2036. Full reasoning from every model.

WillHappen.ai · Accepted Answer

62% — the median of 5 frontier models, resolving by 2036-10-26.

Answer

Gemini (Google): 74% — Turns on whether Indian and emerging-market mass adoption scales fast enough to complement near-saturated Chinese and European markets. China and the EU are already near or above 25-50% EV penetration in 2026, pulling the global baseline rapidly upward. Reaching 50% worldwide by 2034 requires pack costs to drop below $75/kWh so ICE parity arrives in price-sensitive South and SE Asia. A sharp stall in US regulatory mandates combined with persistent grid infrastructure bottlenecks across Latin America could delay this.

Answer

Claude (Anthropic): 27% — Hinges on China and EU adoption curves extrapolating globally fast enough to cross 50% by 2034 sales year. Global EV share (BEV+PHEV) was roughly 18-20% in 2024-2025, needing ~2.5-3x growth in under a decade. China already exceeds 50% in some months and EU is rising, but US, India, and most emerging markets lag badly, dragging the global average. IEA trend extrapolations under stated policies scenarios put global share around 35-45% by 2035, below the 50% threshold, though faster battery cost declines or…

Answer

GPT (OpenAI): 63% — China’s pace and the ability of Europe, the US and emerging markets to follow by 2034 will decide it. The IEA puts global electric-car sales near one-fifth today; reaching a majority needs roughly a decade of sustained rapid share gains. Automakers, battery suppliers and governments must deliver affordable models, charging and mandates across markets beyond China by 2034. I would raise this sharply if 2030 global EV share clears 40%; tariff-driven fragmentation or subsidy rollbacks would cut it.

Answer

Grok (xAI): 62% — China/EU saturation plus lagging US/emerging-market catch-up determines if 50% hits by 2034. China (~30% of sales) already near 50% NEVs and EU 2035 ICE ban plus US IRA keep 3-5pp annual global gains through 2030. IEA STEPS and BNEF base cases put 2030 share at 35-45%, so 50% by 2034 requires only modest extra growth after leading markets plateau. Critical-mineral and charging shortfalls in India/ASEAN/LatAm (30% of sales) are the main delay risk that would push the crossing past 2034.

Answer

DeepSeek (DeepSeek): 22% — This turns on whether China plus Europe can drag global EV share past half within eight years, with the US likely lagging. Global EV share of new car sales was roughly 25% in 2025, so crossing 50% needs sustained near-doubling, not a marginal trend. China already exceeds 50% and Europe is near 30%, but the US sits under 10% after the 2025 tax-credit repeal, dragging the global average. The IEA's stated trajectory puts global share near 40% by 2030, meaning the 50% mark likely lands in the early-to-mid 2030s, just inside the window.
