Elon Musk purchases stake in Twitter after slamming its approach to 'free speech'

Tesla CEO Elon Musk purchased a 9.2% stake in Twitter Inc. according to a Monday filing from the SEC.

Twitter's shares jumped more than 25% in price following Monday's news. Musk now controls nearly 73.5 million shares of the company, making him the largest shareholder, and individual stocks were priced at $49.81 on Monday morning.

Musk's purchase comes roughly a week after the billionaire criticized Twitter for a lack of commitment to free speech.

"Given that Twitter serves as the de facto public town square, failing to adhere to free speech principles fundamentally undermines democracy," Musk tweeted March 26. "What should be done?"
