50% of the Nasdaq 100 made up of just 6 stocks,

With a PE of 143.7, I don't know. Assuming the growth rate stays at 26.9% in 10 years at the current stock price the PE would be ~15. If sales grows at 26.9% a year, in 10 years the revenue would be ~$800 B per quarter or annual revenue of $3.2 T or about 15% of the GDP of the US economy?

Don't disagree with the numbers you have here but they also assume Amazon keeps up the huge investments its making in AWS and other part of business to grow even bigger. If it stopped trying to dominate the world and cut such investments the PE drops a lot and its valuation looks more reasonable. The gross profit on normal activities before reinvestment is impressive.
