Musk was appointed to Twitter's board on April 9, under a deal that prohibited him from acquiring more than 14.9% of the company. Musk made an unsolicited offer on April 14 to acquire Twitter for $44 billion and take the company private. Publicly, Musk expressed that his offer was motivated by concerns with how the company was managed, emphasizing his concern that policies he described as

with the goal of completing the acquisition. On July 12, Twitter opened a lawsuit against Musk to force the sale to proceed. On September 13, 2022, Twitter shareholders voted to approve Elon Musk's takeover of the company. On October 4, 2022, it was reported that Musk offered to proceed with the deal at the original offer price of $54.20 per share. The deal closed on October 27, 2022, with the merger between Twitter, Inc. and X Holdings II, Inc., a wholly owned subsidiary of X Holdings I, Inc., wholly owned by Musk, and Musk took control of the company, paying $54.20 per share, or about $44 billion. By January 2023, Twitter only had around 2,300 employees left, according to Musk, with only 550 working full-time. By April, there were less than 1,500 active employees left with 80% of Twitter's work force gone within a year.
