CATL holds 40.7% global battery share
- CATL tightened its grip on the EV battery business in January through March 2026, taking 40.7% of global usage while BYD stayed a distant second. - The scale gap is huge: CATL installed 99.6 GWh in Q1, versus BYD’s 33.4 GWh, as Korean rivals lost ground on weaker U.S. demand. - That matters because CATL just raised HK$39.2 billion for expansion, while China’s carmakers are stuck with a thin 3.2% margin.
Batteries are where a lot of the money in the EV business is ending up now. Carmakers still get the headlines, but the power balance is shifting upstream — toward the companies that make the cells. That shift got clearer this week when fresh Q1 2026 market-share data showed CATL holding 40.7% of global EV battery usage, way ahead of everyone else. Days earlier, the company also pulled in HK$39.2 billion in a Hong Kong share placement to fund more expansion. ### What exactly happened? The new numbers cover January through March 2026 and come from SNE Research, the battery tracker most of the industry watches. Global EV battery usage reached 244.6 GWh in the quarter, up 9.1% from a year earlier. CATL supplied 99.6 GWh of that total, good for 40.7% share. BYD was next at 33.4 GWh and 13.7%, which means the top spot was not even close. (cnevpost.com) ### Why is 40.7% such a big deal? Because this is not just “market leader” territory — it is ecosystem control. CATL’s share was 38.5% in the same quarter last year, so it actually widened its lead. The company also held 42.1% in the first two months of 2026, which tells you the dominance was not a one-off blip. Even after some M(cnevpost.com). (cnevpost.com) ### Who lost ground? Mostly the South Korean battery makers. LG Energy Solution, SK On, and Samsung SDI all saw share pressure as demand from automakers in the U.S. and Europe stayed softer than expected. That matters because Korean groups have historically been the main non-Chinese counterweight in batteries. If that demand weak(cnevpost.com) to close.

On April 28, 2026, the company said it raised HK$39.2 billion — about $5 billion — by selling 62.385 million new H shares at HK$628.20 each. The point is straightforward: build more overseas capacity and extend its manufacturing footprint(cnevpost.com)ock in the next phase of it.

China’s auto industry posted just a 3.2% sales profit margin in Q1 2026, with total profit down 18% year over year to 78.4 billion yuan. That is extremely (caixinglobal.com)er, more of the value pool shifts to companies like CATL. (autonews.gasgoo.com) ### Is this just a China story? Not really. CATL’s dominance is rooted in China, but the effect is global because battery supply chains are global. A company holding more than 40% of worldwide EV battery usage influences pricing, technology adoption, plant location decisions, and which automakers get the best access to next-generation cells. Basically, battery concentration starts to shape the whole EV map. (cnevpost.com) ### What should readers watch next? Watch whether CATL can turn funding into overseas capacity without running into trade barriers or customer diversification efforts. Also watch whether BYD keeps gaining as both a carmaker and a battery producer — that is the one challenger with real scale.
