Elon Musk is the chief executive officer of Tesla, a leading electric vehicle (EV) company. Tesla and BYD from China are competing fiercely to establish themselves as the world's top EV manufacturer. BYD has outperformed Tesla this year, experiencing a significant increase in sales and revenue. Comparing the two companies, BYD has been successful in driving up its sales and revenue, while Tesla has faced challenges such as declining sales in China, a decrease in its stock price, and public criticism of Elon Musk's involvement with Dogecoin. Despite the fact that BYD sells both hybrid vehicles and EVs, it nearly matched Tesla's EV sales records in 2024. Tesla may struggle to maintain its position as the top EV maker globally as its sales have dropped worldwide in the first few months of the year, while BYD's sales have surged. BYD recently reported impressive annual earnings, surpassing Tesla's revenue for the first time since 2018. The company recorded significant growth in revenue and profits in 2024, although Tesla still leads in terms of net profits. Both Tesla and BYD have diversified revenue streams beyond car sales. Tesla earns a substantial portion of its revenue from energy products and services, as well as by selling regulatory credits to other automakers. On the other hand, BYD is involved in assembling smartphone components, including for Apple's iPhone, which contributes to a portion of its revenue. Tesla's stock price has experienced a remarkable decline since the beginning of the year.
