OpenAI’s post-money valuation reached $852 billion following its record $122 billion funding round closed March 31, 2026, anchored by Amazon, NVIDIA, SoftBank, and Microsoft. Secondary-market platforms such as Forge Global currently imply roughly $880 billion, reflecting continued investor appetite amid rapid revenue growth from ChatGPT and enterprise API usage. CEO Sam Altman’s June 2026 comments indicated a confidential U.S. IPO filing, with an expected listing within the next year that could establish a public-market benchmark before year-end. Competitive pressure from Anthropic, whose secondary shares recently traded above $1 trillion, and ongoing multi-billion-dollar infrastructure commitments add volatility to private valuation assessments used by prediction markets. Key catalysts through December include additional funding tranches, product launches, and regulatory or IPO-related disclosures that could shift implied probabilities.
