Tesla Stock Surges After Elon Musk Buys Nearly $1 Billion in Shares

Tesla shares closed 3.6% higher on Monday after CEO Elon Musk revealed a major stock purchase worth almost $1 billion. The stock climbed as much as 7.5% earlier in the session before settling at levels near $420—a price long associated with Musk’s jokes and Tesla’s market history.

According to regulatory filings, Musk purchased 2.57 million Tesla shares on September 12 at prices ranging between $372.37 and $396.54. This marks his first open-market stock buy since 2020, signaling renewed personal confidence in Tesla’s long-term outlook. Following the surge, Musk took to X (formerly Twitter), posting: “TSLA up $69 to ~$420 as foretold in the prophecy,” fueling the ongoing meme culture around Tesla’s share price.

Analysts also weighed in on the move. William Blair’s Jed Dorsheimer called the purchase “a clear signal of confidence from Musk,” particularly in relation to Tesla’s highly anticipated robotaxi business. The company is expected to accelerate its rollout of autonomous vehicles, a key driver of future growth.

Despite ongoing concerns about shrinking margins as environmental tax credit revenues decline in the second half of 2025, investor sentiment appears strong. Tesla’s momentum in delivery expectations and robotaxi development is contributing to growing bullishness on Wall Street.

Dorsheimer, however, maintained a Market Perform rating, noting that while Musk’s buy underscores confidence, broader challenges remain. Still, Musk’s significant investment has reassured many investors who see it as a powerful vote of confidence in Tesla’s ability to navigate short-term headwinds and capitalize on long-term opportunities.

With Tesla stock reclaiming the $420 mark for the first time since January 2025, Musk’s bold purchase and the market’s reaction highlight the enduring influence of both the CEO and the company in the electric vehicle sector.
