Elon Musk has taken a 9.2% stake in Twitter to become the platform’s biggest shareholder, a week after hinting he might shake up the social media industry.
Twitter shares surged about 26% in premarket trading after the regulatory filing released Monday detailing Musk buying the holding. The stake is worth about $2.89 billion, based on Friday’s market close.
Musk, 50, polled his more than 80 million followers on Twitter last month, asking them whether the company adheres to the principles of free speech. After more than 70% said no, he asked whether a new platform was needed and said he was giving serious thought to starting his own.
Musk has been one of the biggest personalities on Twitter and has regularly run into trouble on the platform. The Tesla chief executive officer is currently seeking to exit a 201 deal with the U.S. Securities and Exchange Commission that put controls in place related to his tweeting about the electric-car maker.
The announcement will be yet another major test for new Twitter CEO Parag Agrawal, who replaced Jack Dorsey after he unexpectedly resigned in November. Agrawal vowed to increase accountability, make decisions faster and to improve product execution.
The company set ambitious goals for growth including increasing annual revenue to $7.5 billion and getting to 315 million daily users by the end of 2023.
Musk posted a cryptic meme in December after Twitter announced that Agrawal was taking over from Dorsey as Twitter’s CEO. It depicted Agrawal as Soviet dictator Joseph Stalin and Dorsey as Soviet secret police head Nikolai Yezhov being shoved into water.
Twitter is under pressure to move faster in building new products. The company has set ambitious revenue and user growth goals to convince skeptical investors that it was serious about expanding its business.
While Twitter has grown steadily for years, its stock gains have lagged behind industry peers. Musk has lambasted Twitter’s recent development of profile pictures linked to non-fungible tokens, saying the social media company has the wrong priorities.
