OpenAI Valuation Soars to $500 Billion After Secondary Share Sale

OpenAI has reached a new milestone, achieving a $500 billion valuation that makes it the world’s most valuable private company, surpassing SpaceX and widening the gap with competitors like anthropic and ByteDance.

The staggering valuation follows a secondary shares sale, first reported by Bloomberg, that allowed current and former employees to sell stock to investors including Thrive Capital, SoftBank, Dragoneer Investment Group, and T. Rowe Price. The sale didn’t bring new funding to the company but increased its valuation from $300 billion in March, when it raised $40 billion in a round led by SoftBank.

Founded in 2015 as a non-profit dedicated to advancing AI, OpenAI later adopted a capped-profit structure. Currently,the company boasts around 700 million weekly users and $12 billion in annualized revenue. It’s secured significant cloud deals, notably a $300 billion five-year partnership with Oracle for computing power.

OpenAI is also undergoing a transition towards a for-profit structure. A non-binding deal was signed last month with Microsoft,its largest shareholder,to convert its for-profit arm into a public benefit corporation controlled by the remaining nonprofit.

Elon Musk, who left OpenAI in 2018 to launch xAI, has become a vocal critic, filing lawsuits to halt restructuring efforts and accusing the company of prioritizing profits over its original mission. He also recently sued the company alleging the theft of trade secrets by former xAI employees.

Secondary shares sales are gaining traction as a way to reward and retain staff and have boosted valuations for other companies, including SpaceX ($400 billion), Stripe ($50 billion), and Databricks ($16 billion).

How might OpenAI’s $500 billion valuation impact investment and competition within the broader AI market?
