Blackstone Inc. holds a 6.7% equity stake in Firmus Grid, and joined a $2 billion funding round for the firm in August 2026.[^1]

Ramp reached a valuation of $60 billion following a new funding round, as reported October 9, 2026.[^2]

In August 2026, Ramp launched Router.com, a tool built to select AI models for corporate users in order to reduce running costs.[^3]

These appear to be parallel bets placed one month apart: one on raw compute grid infrastructure, one on the software layer that allocates work across that infrastructure.
