X (formerly twitter) went public in Nov 7, 2013 via ipo, with an offering valuation of approximately $33B. Twitter was a public company from November 2013 (IPO at $26/share) until October 27, 2022, when Elon Musk completed his $44 billion acquisition, delisting the company from NYSE. The platform was rebranded to X in April 2023, and Twitter, Inc. itself ceased to exist as a legal entity when it was merged into X Corp. (disclosed in an April 2023 court filing). In March 2025, X merged into xAI in an all-stock transaction forming X.AI Holdings, so this profile's entity is no longer independent and no longer a listing candidate in its own right - hence 'acquired' rather than 'private'. As of May 2026, the company remains private under SpaceX/xAI ownership following SpaceX's acquisition of xAI in February 2026.
X (formerly twitter) raised $44.76B across 11 disclosed funding rounds prior to its public listing.
