Blackstone and Halliburton Invest $1B in VoltaGrid — AI Data Center Power Startup Valued at $10B+

Bloomberg·high signal

Blackstone and Halliburton are investing $1 billion ($775M primary, $225M secondary) in VoltaGrid, a Houston startup building gas-powered microgrids for rapid data center deployment, valuing it at over $10 billion. VoltaGrid will also acquire its key supplier Propell Energy to reduce execution risk across its 7.5 GW order book through 2030. Energy is now the binding constraint on AI infrastructure — not chips — and Halliburton's oilfield expertise partnering with Blackstone's capital signals the energy-AI convergence is accelerating.
