Ultimately what matters is current revenues and profits not the future estimate of revenues and profits by bunch of casino gamblers. If you just look at revenues, Apple is ahead but by not absurd amounts. For example, AT&T had revenues of $39B while Apple had $53B. The combined revenues of only AT&T and Disney is more than sufficient to beat Apple.
Current revenues and profits are a drop in the bucket compared to the next 30 years, you should focus mostly on the future.
And these aren't casino gamblers, prices are ultimately set by the professionals who analyze this stuff full-time for a living. The market cap is simply the "wisdom of the crowds" who are putting their money where their mouth is.
If you have a better way of calculating the worth of companies, then you'll become extremely, extremely, extremely rich. Good luck.
To the question, ‘which would you rather have: a trillion US dollars cash, or ownership of apple?’, the market has said ‘apple’
So... yes, that is what apple’s ‘worth’.
But just ask yourself, over the next 30 years will somebody produce that much profit for the company? Think of the 10 cell phones, 7 laptops, 5 iPads, Apple Music subscription, etc. that you'll purchase over the next 30 years. If you spend $1,000/yr on Apple products and it's 20% profit, they make $200/year x 30 years = $6,000. Then discount accordingly...
There's nothing crazy about it, no shark-jumping necessary.
