AI firms account for over 80% of S&P 500 gains this year; AI sovereignty is an economics problem

India's Chief Economic Adviser V. Anantha Nageswaran and Debjani Ghosh argue in Mint that AI sovereignty is an economics problem, not a technology one. Using South Korea as a case: the Kospi fell roughly a third from its June peak as investors doubted AI buildout profitability, then jumped 17.9% on July 31 after US cloud giants reaffirmed spending. Samsung and SK Hynix carry over half the index weight, making Kospi a live readout on global AI capex.
Key data: AI-related firms account for over 80% of S&P 500 gains this year; ex them, the index barely moved.
Two observations: (1) Circular financing: hyperscalers fund chipmakers who supply those same hyperscalers; model companies sit on both sides of contracts, flattering growth on the way up and amplifying on the way down. (2) Chokepoints have lead times: lithography, leading-edge fab, HBM, software locking in dominant chips, minerals refining each take 5-10 years; any sovereignty plan shorter than a decade is a procurement plan wearing a strategy label.
The real question is not self-sufficiency or shelter under a patron, but knowing precisely which dependencies you can live with and which you cannot.
