AI Economics, Bubbles & Systemic Risks
ฟองสบู่ AI กำลังจะแตก: ใครคือ "เดอะแบก" ของเศรษฐกิจ?
Summary
The Magnificent 7 are the large technology companies now accounting for 25 to 30% of the entire US market capitalisation.
The risk lies in how tightly they are coupled to NVIDIA, which makes the interdependence larger than any single company’s numbers suggest.
The talk sets it against the dot-com era and asks whether the pattern repeats.
Key points
Concentration is itself the risk
When seven companies hold a quarter of the market, company-specific risk becomes systemic risk.
The revenue circulates inside the group
They buy chips from NVIDIA and NVIDIA grows on them, a loop that amplifies both directions.
Dot-com is an imperfect comparison
This time the companies are genuinely profitable, which has to be counted before drawing the parallel.
People who own no shares are still exposed
Pension funds and index products hold this group on behalf of savers who never chose it.
