OpenAI is reportedly in negotiations to acquire Windsurf, an AI-powered coding tool, for approximately $3 billion. This market resolves to 'Yes' if OpenAI officially announces the completion of the acquisition by December 31, 2026. Source
@JussiVilleHeiskanen As of today, June 6, 2025, the acquisition of Windsurf by OpenAI has been widely reported as an agreement to acquire, but the deal was explicitly stated as not yet finalized or closed in reports from early May 2025.
Large acquisitions like this typically involve a period after the initial agreement where legal, regulatory (like antitrust reviews), and financial due diligence are completed. Neither OpenAI nor Windsurf have made a formal public announcement that the deal has officially closed.
