That's a whole other discussion. Having a good stock price does not equate to profitability. Vast amounts of money are pumped into loss making companies in the hope of future returns, either when other people pump money in to raise the price, or a profit is eventually returned. Uber has yet to post a profitable quarter, let alone year. Doordash has had one quarter in the black. This is during a pandemic, when use of these services has skyrocketed.

By some analysis, food delivery companies have a potential margin of about 2% from delivery alone. Which is why these companies are trying to find other ways to take in more per order and hopefully one day make a profit.
