When you look at the annual subscription amount, FSD's $1,188 ranks as the highest on this list and Starlink's ~$792 is the second highest.
This will make easier for Tesla and SpaceX to climb the ranks of the largest annual subscription revenue businesses.
For example, to reach Microsoft's $99 billion in annual Office 365 revenue, Starlink would need 125 million subscribers and Tesla's FSD would need 83 million.
