Huge negative margins, according to the article:

  "Starting with the reusable rockets, MS expects SpaceX to eat itself. Launch costs will collapse by more than 99 per cent versus their historical average within 10 years, it says. Operating margin on launches will have jumped to about 40 per cent, from around negative 50 per cent currently, but 40 per cent of less than 1 per cent still isn’t very much."

Though as someone (probably JumpCrisscross, can't remember) pointed out a previous time this came up, as SpaceX is selling launch to Starlink, and also own Starlink, which one of the two gets to count as making a profit or a loss is just a matter of preference.
