Overview

Forbes reported on September 3, 2026 that the company closed a $1.5 billion round led by Jane Street at a valuation above $18 billion, after an earlier 2026 financing at a $7.5 billion valuation. The latest round is reported rather than company-announced, so VCT should preserve that evidence distinction.
