Social platform X struggled after Elon Musk took over, but its fortunes improved dramatically after US President Donald Trump won reelection. Now it will be become part of Musk's AI startup xAI.

The move will “unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach,” he wrote on X.

The all-stock deal values xAI at $80 billion and X at $33 billion, according to Musk’s post. The billionaire has increasingly linked the two companies, wielding user data from X to train its AI models.
