After the Battery Boom, a Reality Check for 2026

After EV demand cooled in 2025, U.S. battery makers head into 2026 slowing projects, trimming capacity, and rethinking growth

14 Feb 2025

At the height of America’s electric-vehicle optimism, battery factories seemed to sprout everywhere. Lavish subsidies, bold sales forecasts and geopolitical worries about supply chains combined to produce a frenzy of gigafactory announcements. As 2026 approaches, that rush is giving way to restraint.

Demand for electric cars did grow through 2025, but far more slowly than many firms had expected. Carmakers responded by trimming production targets and managing swollen inventories. Battery makers, whose expansion plans were built on earlier assumptions, have followed suit. Delays, pauses and recalculations are now more common than ribbon-cuttings.

The shift is visible at Ultium Cells, the joint venture between General Motors and LG Energy Solution. Late last year GM confirmed workforce reductions and temporary production pauses at Ultium’s Ohio plant. The company cited softer vehicle demand and the need to bring battery output back in line with orders. The episode underlined a problem facing the industry, capacity was built for a market that has yet to arrive.

Only a handful of projects have been scrapped outright. Freyr Battery walked away from a $2.6bn plant in Georgia in early 2025, blaming capital constraints and weaker market conditions. KORE Power dropped plans for a large factory in Arizona around the same time. These cancellations are notable precisely because they are rare. Most other projects remain alive, but on stretched timelines or with reduced scale.

That distinction matters. America’s largest investments, those backed by established suppliers and carmakers, are still moving ahead. Firms are signalling not a retreat from domestic manufacturing, but a more cautious and disciplined approach. Growth, once taken for granted, now has to be earned.

Battery makers are also looking beyond passenger cars. Interest in grid-scale storage and commercial energy systems rose through 2025 as companies sought steadier demand and better utilisation of their plants. Diversification is becoming a hedge against the volatility of car sales.

Policy adds another layer of uncertainty. Changes to federal tax credits and shifting eligibility rules muddied demand forecasts last year. Subsidies still matter, but their effects are less predictable, encouraging firms to temper their ambitions.

America’s battery industry is thus moving from exuberance to execution. Gigafactories remain central to industrial strategy and climate goals. But as the market enters 2026, realism has replaced hype, and caution is the new competitive advantage.
