Several backers of Elon Musk’s $44 billion acquisition of X are now set to receive a windfall from their investments in xAI.

Financial giant Fidelity bumped up the valuation of two Elon Musk-owned companies, social media platform X and AI startup xAI in October.

X is worth 72% less than the $44 billion owner Elon Musk paid for the app formerly known as Twitter, despite that Fidelity had recently marked up the value of its shares by 32.37%, according to a valuation from Fidelity.
