In its energy business, Tesla said that it deployed 8.8 gigawatt hours of battery energy storage systems in the first quarter, following a record of 14.2 gigawatt hours in the fourth quarter of 2025. In Q1 of 2025 the company deployed 10.4 GWh of its energy products. Tesla's battery energy storage products include its Powerwall backup batteries for homes, and larger Megapack and Megablock systems used alongside data centers and utilities. Tesla shares dropped 15% in the first quarter, continuing a trend that started two years ago.

Iran has retaliated by targeting ships trying to pass through the Strait of Hormuz.
