DeepMind Alum’s AI Startup Hits $5.1 Billion Valuation as Founder Pledges Proceeds

Ineffable Intelligence, founded by former Google DeepMind researcher David Silver, is entering an increasingly capital-intensive race to develop advanced artificial intelligence. The startup’s rapid ascent highlights how funding and technical talent are concentrating around a small group of AI companies. Silver’s charitable commitment also adds to a broader debate over whether the wealth created by the AI boom can offset concerns about industry power, inequality and the ethics of accelerating development.

Ineffable Intelligence has raised $1.1 billion in financing at a valuation of $5.1 billion, according to the latest report. Silver has pledged through Founders Pledge to donate all of his personal proceeds from any future sale of the company to charity. The report did not specify the closing date of the financing or when Silver signed the pledge, leaving the timing of both milestones undisclosed.
