Revenue % increases between Q1 vs Q4 in a given year:
2018: 112% increase, $3.41B -> $7.23B
2019: 63% increase, $4.54B -> $7.38
2020: 79% increase, $5.99B -> $10.74B
2021: XX% increase, $10.3B -> ????
Using really sophisticated math, I averaged out the % increases (even though there's a high likelihood it'll go over). It comes out to 84% if they have an average year in 2021 in terms of Q1 -> Q4 growth.
Q4 projected revenue (on back of the envelope math):
$19B. That'd be an annualized run-rate of $76B at the end of Q4. Just looking at standard multiples the company is trading at now (~20x):
Thats
~$1.5T market cap company by end of 2021.
