Tech entrepreneur Elon Musk on Friday announced he has sold his micro-blogging website X to his own AI firm xAI.

Musk said, "Since its founding two years ago, xAI has rapidly become one of the leading AI labs in the world, building models and data centers at unprecedented speed and scale."

The entrepreneur said: "X is the digital town square where more than 600M active users go to find the real-time source of ground truth and, in the last two years, has been transformed into one of the most efficient companies in the world, positioning it to deliver scalable future growth."

Musk said xAI and X’s futures are intertwined. 

"Today, we officially take the step to combine the data, models, compute, distribution and talent," he said.

Musk said this step will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.

"The combined company will deliver smarter, more meaningful experiences to billions of people while staying true to our core mission of seeking truth and advancing knowledge. This will allow us to build a platform that doesn’t just reflect the world but actively accelerates human progress," Musk said.
