Warren Buffett invested $232 million in BYD in 2008. At the company's peak valuation, that stake was worth over $9 billion. Buffett is not known for technology bets, and BYD was not yet the company it would become. The investment looked speculative at the time. It turned out to be one of the most accurate reads of an industrial company's long-term position in modern investment history. BYD generated $107 billion in total revenue in 2024, having grown from $32.6 billion just three years earlier in 2021. The company delivered 1.76 million battery electric vehicles in 2024, surpassing Tesla in BEV volume — a milestone that would have seemed fantastical when Wang Chuanfu founded the company in Shenzhen in 1995 as a rechargeable battery manufacturer. The path from lithium-ion battery cells to global EV market leadership ran through a single, obsessively executed strategy: vertical integration so complete that BYD makes components most automakers treat as irreducibly external. BYD manufactures its own IGBT power semiconductors through BYD Semiconductor — the only automaker in the world to do so at scale. When the 2021-2022 global chip shortage was halting production lines from Detroit to Stuttgart, BYD was largely insulated. The company's Blade Battery, introduced in 2020, uses a prismatic LFP design that eliminates the battery module layer entirely, reducing pack weight by 10% and assembly time by 15%. These are not marketing claims — they are engineering choices with direct cost consequences. The resulting structural cost advantage is estimated at $3,000-5,000 per vehicle versus competitors using third-party component suppliers. At 700,000 employees and operating across multiple continents with an expanding overseas sales network, BYD has built a manufacturing organism that scales faster than any traditional automaker because it does not depend on an external supply chain that constrains its growth.
