Elon Musk Says He’s Back to 7-Day Workweeks, Sleeping in Office as Wartime CEO

Tech billionaire Elon Musk has revealed that he's once again working 7 days a week and sleeping in the office, calling himself a “wartime CEO” as his companies face major product rollouts and competitive pressures.

In a recent post, Musk said:

“It’s back to hardcore mode. I’m sleeping on the factory floor and pushing everyone to give their best.”

This work ethic harks back to his early days at Tesla and SpaceX, when he famously lived in the office during intense production phases.

As Tesla, X (formerly Twitter), and SpaceX juggle big developments — including AI projects, Mars mission planning, and robotaxis — Musk’s hands-on leadership style signals high-stakes ambition.
