Taiwan Semiconductor Manufacturing Company has approved a capital expenditure budget of $31.28 billion, a massive commitment to expanding chip production capacity amid surging demand for artificial intelligence hardware, according to the Economic Times.

The investment comes as TSMC's grip on the global foundry market reaches extraordinary levels. The company captured 72.3% of foundry market share in the first quarter of the year, according to Businesskorea — meaning nearly three out of every four chips manufactured for outside customers worldwide were made by TSMC.

The scale of that dominance is hard to overstate. TSMC does not design chips itself; it builds them for others. Its customer list includes virtually every major technology company that needs cutting-edge silicon.

Nvidia CEO Jensen Huang has made no secret of the relationship's value. According to Barchart, Huang described AI as "insanely profitable" for TSMC — a candid acknowledgment of how central the Taiwanese chipmaker has become to the AI boom reshaping the technology industry.

The $31.28 billion capital budget is aimed at building the production capacity needed to keep pace with that demand. Training and running AI models requires enormous quantities of advanced semiconductors, and TSMC remains the only company currently capable of manufacturing the most cutting-edge chips at scale.

Why it matters: TSMC's ability — or inability — to expand fast enough will shape how quickly AI products improve, how much they cost, and which companies get access to the chips needed to build the next generation of technology.
