OpenAI is raising approximately $6.5 billion at a $150 billion pre-money valuation, the largest venture capital round ever recorded, surpassing xAI's $6 billion round earlier in 2024. The round is oversubscribed with Thrive Capital leading and likely backers including Apple, Nvidia, and Microsoft. This marks a historic shift in capital concentration in frontier AI development, with OpenAI requiring a $250 million minimum investment and turning away billions in excess demand, signaling severe portfolio concentration risk acceptance by lead investors.
