Elon Musk Buys $1 Billion in Tesla Shares

For the first time in almost five years, Elon Musk has purchased shares of his own company Tesla on the open market. According to CNBC and SEC filings, Musk bought 2.57 million Tesla shares on September 12 for a total value of around $1 billion.

This marks the largest insider stock purchase in Tesla’s history. Following the news, Tesla stock closed trading that day up 7.35% at $395.94 per share, and on Monday, September 15, the stock peaked with an 8.06% gain.

Before the transaction, Musk held roughly 13% of Tesla’s shares. His purchase comes shortly after Tesla approved a temporary stock-based compensation package worth about $30 billion in August, aimed at retaining him as CEO. In November, shareholders are set to vote on an even bigger performance-based bonus package that could reach $975 billion, distributed in 12 tranches if Tesla meets ambitious growth targets over the next decade.

To unlock the full payout, Musk must increase Tesla’s market value to at least $8.5 trillion. By comparison, Tesla’s current market cap is around $1.3 trillion, while NVIDIA holds the title of the world’s most valuable company at about $4.3 trillion.

Meanwhile, Tesla’s market share in U.S. electric vehicles has dropped to 38% in August 2025, the lowest level since 2017, due to increasing competition from rivals.
