OpenAI's preparations for a potential 2026 IPO gained momentum in May when reports emerged that the company had engaged Goldman Sachs and Morgan Stanley to draft a confidential filing with regulators, targeting a public debut as early as September. This follows earlier groundwork laid in late 2025 for a valuation potentially reaching $1 trillion amid explosive revenue growth to around $20 billion in 2025 from its flagship large language model, ChatGPT. Competitive pressure from rival Anthropic, which recently filed its own confidential paperwork, adds urgency, though OpenAI has stated an IPO is not its focus and internal timelines remain fluid. Key upcoming catalysts include any formal SEC submission and ongoing pre-IPO funding rounds that could influence listing readiness.
