Taiwan: the choke point
Advanced chip production and the AI supply chain are still heavily centralized in Taiwan, leaving global AI and cloud providers exposed to a single geographic bottleneck. Even if more wafer fabs are built elsewhere, key downstream steps—advanced packaging and final assembly—often still happen in Taiwan, and TSMC’s supplier‑verification system is becoming an industry standard that others are aligning with ( ). The commercial picture underlines the risk: TSMC reported strong March revenue and Nvidia still controls roughly 80–85% of the AI‑accelerator market as demand surges toward a huge industry milestone ( ).
The world’s most important artificial intelligence chips can now be etched in more than one country, but many still have to go back to Taiwan to be turned into finished products. A new wave of reporting this week says the bottleneck is no longer just chipmaking itself, but the last steps that connect, stack, package, and ship those chips at scale. (benzinga.com) Taiwan Semiconductor Manufacturing Company is still the center of that system. Fast Company reported on April 9 that most advanced chips, including the ones used for artificial intelligence, are still produced on Taiwan, an island Beijing continues to claim as its own. (fastcompany.com) A chip factory makes the silicon wafer, which is the thin round sheet where the circuits are printed. Advanced packaging is the next step, where those finished pieces are wired together like a dense three-dimensional Lego set so a server can actually use them. (benzinga.com) That second step is where the map gets narrow again. Benzinga reported on April 9 that even chips manufactured in the United States are still being shipped to Asia, mainly Taiwan, for final assembly because packaging capacity remains concentrated there. (benzinga.com) This matters most for artificial intelligence servers because they do not run on a single chip. Nvidia’s Blackwell systems, for example, depend on multiple high-bandwidth parts being packed together with extreme precision, which makes packaging capacity almost as strategic as the factory that printed the chip in the first place. (ibtimes.com.au; benzinga.com) The supply chain is also being shaped by Taiwan Semiconductor Manufacturing Company’s rules, not just its factories. DigiTimes reported on April 9 that the company’s supplier verification and management system is increasingly becoming the standard that Samsung, Intel, and Japan’s Rapidus are aligning with. (digitimes.com) That means Taiwan Semiconductor Manufacturing Company is exporting a playbook as well as a product. If rival chipmakers adopt the same supplier checks, audits, and qualification methods, the industry becomes easier to coordinate around Taiwan’s model and harder to reroute quickly in a crisis. (digitimes.com) The demand side is not cooling off while this dependency gets sorted out. Taiwan Semiconductor Manufacturing Company said on April 10 that March 2026 revenue reached about New Taiwan dollar 415.19 billion, up 30.7% from February and 45.2% from March 2025, with first-quarter revenue up 35.1% year over year. (tsmc.com) At the same time, the buyers are still crowded around one seller. International Business Times Australia reported on April 10 that Nvidia still controls roughly 80% to 85% of the artificial intelligence accelerator market, while generative artificial intelligence chips alone are projected to approach $500 billion in revenue this year. (ibtimes.com.au) So the risk is not just “Taiwan makes a lot of chips.” The risk is that one island still sits in the middle of the wafer, the packaging, the supplier approvals, and the biggest customer boom in the market all at once.
