Share figures are for installed EV battery capacity and vary by period (calendar year vs Jan–Nov 2025); they measure gigawatt-hours installed, not cell quality, safety or profitability. Source: SNE Research.
The most important fact is not who is number one — it is how concentrated the market is. Two companies (CATL and BYD) install over half the world's EV batteries, and Chinese manufacturers as a group install about 70%. That concentration shapes everything downstream: pricing power, technology roadmaps (LFP vs NMC) and supply-chain risk. A buyer or analyst who reads the rankings without the concentration misses the story.
BYD's share is unusual because much of it is self-consumed — BYD makes both the batteries and the EVs they power. That vertical integration is structurally different from CATL, which sells cells to many automakers. It matters when comparing the two: CATL's share is a measure of its customer base; BYD's is partly a measure of its own vehicle sales.
Position: The number worth remembering about the EV battery market is not "CATL is first" — it is "China installs about 70%," because that single concentration explains pricing, supply risk and policy more than any individual ranking.
Reasoning: Rankings change slowly; concentration is structural. Once you see that two Chinese companies hold over half the market and China holds 70%, the price and supply dynamics follow — and the Korean and Japanese tier is fighting for the remaining share in a market whose centre of gravity is already set.
