The market for Starlink in the USA is pretty small compared to the cable market, but, the exact same satellites that are being used to service the USA’s 5 million user recevers, will also service the other 15/16 of the land area of the planet. The number of subscriptions will be proportional to the area.
Starlink is going to be magnificently profitable in its first incarnation, and any upgrades will multiply that profitability a magnitude or two. Then add on the content and endpoint services — don’t be suprized if you hear Starlink is buying Disney, etc.
Starlink will be bigger than Tesla.
The more I read about Starlink and think of the potential, it is really mind boggling. Musk could be the worlds first Trillion dollar man.
