OpenAI Confidential IPO Filing Joins Race for Largest Public Listing Ever | PYMNTS.com

OpenAI has filed a confidential IPO prospectus, joining a race for what could become the largest public listing ever, amid headlines about Anthropic and SpaceX potentially following suit. OpenAI emphasized that no timing has been set, noting that staying private could be easier for certain steps, while keeping the option to go public if market conditions are favorable. The company was valued at $852 billion in a March funding round that produced $122 billion in capital, and it reported monthly revenue of about $2 billion, up from $1 billion per quarter at the end of 2024. CFO Sarah Friar highlighted potential future capital raises to match compute demand, signaling flexibility for the IPO path.
