$5 to $7 Trillion? Developing cutting edge chip fabrication technologies is insanely expensive but that number still strikes me as far too high. Unfortunately, the article doesn't go into any detail on the allocation of funds for a capital raise that unprecedentedly massive. I don't doubt that Altman may have cited that range, my skepticism is more centered on the practical possibility of productively putting that much money to work in a relevant startup time frame (~five years). Maybe there's missing relevant detail, like perhaps he was referencing a cumulative total spend over a decade or longer.<p>Just for comparison TSMC's market cap is ~$500B, ASML (who makes the cutting edge fab machines) is ~$350B. NVidia itself is ~$1.7T but that also includes non-AI things. Even if you include buying smaller players in addition to those, you could theoretically outright own the entire relevant market for less than $3T. And that's at full de-risked, retail public market price in a very frothy time period. The new venture cost should be less, otherwise investors would be wiser to just buy the existing players with all their IP, proven know-how and market momentum.
