Elon Musk's X, formerly known as Twitter, is a social media platform that Elon Musk acquired in October 2022 for $44 billion. Since Musk's takeover, X has been undergoing a transformation into an "everything app" with the integration of financial services. X is now privately held, and direct public investment is not possible, but accredited investors and institutions can trade the stock.
X is developing investment and trading features, potentially including access to stocks and digital assets like Bitcoin. CEO Linda Yaccarino mentioned the company is planning to roll out in-app trading and investment features that could include a branded debit or credit card. X has also obtained money-transmitter licenses in several U.S. states to expand its financial services. As of March 2025, investors valued X at $44 billion. X holds a stake in Elon Musk's AI startup, xAI, which develops Grok, an AI model.
