Since its last private valuation of $380 billion in February 2026, the company has expanded its customer base to include eight of the Fortune 10 firms and over 500 clients generating more than $1 million annually. The company’s revenue is reported to be over $30 billion in run rate as of April 2026, with a gross margin reportedly around 40%.
