"Chapter 7 of Title 11 of the United States Code (Bankruptcy Code) governs the process of liquidation under the bankruptcy laws of the United States, in contrast to Chapters 11 and 13, which govern the process of reorganization of a debtor. Chapter 7 is the most common form of bankruptcy in the United States."
Airlines get free government money though. Will twitter? If not, Twitter will need to borrow more money and at higher interest rates compared to market rates if they go through with bankruptcy.
Funny thing about the bankruptcy hypothesis is that the owner of Twitter is the richest man in the world and could literally pay old twitters expenses for decades even if it never made a penny. If we are just talking about the debt payments, he has a 200 year runway.
Actually be probably can't. Musk's wealth is largely on paper, as Tesla stock. Which is enormously overvalued and has been plummeting since he bought Twitter. If Twitter needs cash injections, he has to sell more Tesla, which will depress the price further.
