Potential to be a >$50bn tech company seems to be a pretty generous one to be considered blockbuster. Especially considering the frothy valuation scene. There is no point in comparing with low margin business like Target. Let's look at the biggest tech companies today - Apple (~$600bn), Google (~$500bn), MSFT (~$450bn), Facebook & Amazon (~$250bn), Oracle (~$250bn) so on and so forth. If we are concluding that NYC is catching up to Silicon Valley, then at least one startup needs to demonstrate potential to be worth 10% of Google. That doesn't seem extraordinarily high metric to me.
I think its fair benchmark. Adobe ($48B) is a relatively successful company of decent size- Not as big as Google and not as small as a borderline unicorn
