Despite Nvidia's share price tripling this year, the company faces risks due to the capital-intensive nature of chip production and limited output. Asian chipmakers, who manufacture all of Nvidia’s chips, have reported their lowest earnings in years. The production of high-end chips is capped due to the high cost of building a chip fabrication facility and the need for continual upgrades. Furthermore, AI chips, which are expected to drive unprecedented demand, will only make up a small part of the total sales for chip manufacturers.
