The business magnate Elon Musk initiated an acquisition of American social media company Twitter, Inc. on April 14, 2022, and concluded it on October 27, 2022. Musk had begun buying shares of the company in January 2022, becoming its largest shareholder by April with a 9.1 percent ownership stake. Twitter invited Musk to join its board of directors, an offer he initially accepted before declining. On April 14, Musk made an unsolicited offer to purchase the company, to which Twitter’s board responded with a “poison pill” strategy to resist a hostile takeover before unanimously accepting Musk’s buyout offer of $44 billion on April 25.
