Plunging U.S. revenue at X risks opening up a "massive hole" on its balance sheet that Musk needs to plug to stave off its financial collapse.

Musk’s repeated outbursts against advertisers have dried up the main source of revenue for the loss-making company formerly known as Twitter.

At some point, he will have to provide a fresh infusion of cash to salvage his $44 billion takeover.
