Fair points, both you and akiselev; thanks for the clarification I am not an especially economically-(or even really quantitatively) inclined person; I just see GDP bandied about as a metric of "size of economy" and market cap as "value of company". Revenue is probably locatable if someone wants to dig into quarterlies... I probably spent too much time on this exercise already

It's actually pretty easy but for a first order estimate: http://wolframalpha.com/input/?i=total+2015+revenue+of+Google+%2B+Apple+%2B+Autodesk+%2B+eBay+%2B+Facebook+%2B+Intel+%2B+LinkedIn+%2B+Marin+software&x=0&y=0 http://wolframalpha.com/input/?i=total+2015+revenue+of+Googl... I'm on mobile so I can't get the interface to work properly but it's much easier on desktop Mathematica or WolframAlpha. In the above figure, I only included names from the OP that I was certain were public after a quick glance and I didn't even get to Microsoft. The number is something like $500 billion a year but as a sibling comment to yours mentions, this includes international revenue that may never make it to the US. Accurate data on this scale is hard to come by without a working Bloomberg terminal.

Here's a very, very rough ballpark estimate based on your data: - $2.7T in market cap - let's say average P/E ratio is 25 (P/E is approximately the ratio of company valuation to annual profits) - let's say the profit margin of a typical tech company is 20% - let's say 40% of a typical tech company's revenue is in the US Estimated US revenue of the companies in your spreadsheet: $2.7T / 25 / 0.20 * 0.40 = $216b (about 1.5% of GDP, which is still huge) By the way, I think your initial estimate of the total market cap of companies signing the brief is quite useful and informative, it just shouldn't be compared to GDP :)
