OpenAI Closes Record $122 Billion Funding Round at $852 Billion Valuation — Largest Private Tech Raise in History, IPO Imminent

On March 31, 2026, OpenAI announced the close of the largest private funding round in technology history: $122 billion in committed capital at a post-money valuation of $852 billion.

Round Details: The round was co-led by SoftBank alongside Andreessen Horowitz and D. E. Shaw Ventures. Key strategic investors include:

• Amazon: $50 billion commitment
• Nvidia: $30 billion commitment
• SoftBank: $30 billion commitment
• Microsoft: participated (amount undisclosed)
• Additional $12 billion from broader pool including $3 billion from individual/retail investors through bank channels — a first for OpenAI

Financial Metrics:

• $2 billion monthly revenue (as of March 2026)
• $13.1 billion total revenue in 2025
• 900+ million weekly active ChatGPT users
• 50+ million paid subscribers
• Company remains unprofitable

IPO Implications: The round is widely seen as pre-IPO positioning. OpenAI has been actively cutting costs, shuttering Sora and pulling back from some spending plans.

Market Context: At $852B, OpenAI would rank among the 10 most valuable companies globally if public. The inclusion of retail investors signals a broad base ahead of what could be the most anticipated tech IPO since 2012.
