Igor Babuschkin, an xAI cofounder, is raising up to $1 billion for his new AI research startup, River AI, committing $100 million of his own money.
What: Igor Babuschkin, a cofounder of xAI, is in talks to raise up to $1 billion for his new AI research startup, River AI, incorporated in Nevada on April 20, 2026. Forbes reported on May 14, 2026, that the company is targeting a valuation of up to $5 billion, with VC firm General Catalyst reportedly leading the round. Babuschkin is personally investing up to $100 million.
