Starlink Rumor: $70-80B IPO in 2022

Rumor has it Starlink is planning to IPO in about 12 months, for a target valuation of $70-80B. The most recent subscriber update from Elon Musk in late August said Starlink had ~100,000 users ($119M revenue run-rate). My projection is for them to hit 1,000,000 users by the end of 2022, scaling to over a $1B revenue run-rate. Also it looks like Starlink is developing a next generation satellite dish/terminal, that is designed for cheaper shipping, improved performance, and mass production. Would you buy Starlink at $70-$80B when it IPOs?
