OpenAI

OpenAI reached a $157 billion valuation in its October 2024 funding round led by Thrive Capital, making it the most valuable private AI company in history. Generating $3.4 billion in annualized revenue from ChatGPT Plus, API access, and enterprise contracts, it has outpaced Anthropic by more than 2.5x in both valuation and revenue. Its transition to a for-profit structure set the stage for a potential IPO, further solidifying its lead.
