(AI-generated image)* Taiwan Semiconductor Manufacturing Company approved on Nov. 10, 2026, equity investments of up to $1 billion across artificial intelligence developers Anthropic and OpenAI to deepen ties with premier model builders. The board authorized up to $500 million to buy Anthropic common shares at its public debut and up to $500 million in OpenAI preferred stock, the company said in a regulatory filing. The $1 billion allocation represents 2.4% of the $40.93 billion capital appropriation that directors approved in the same meeting. The capital budget funds advanced technology construction, packaging capacity and 2027 research facilities. The investment also equates to 4.2% of TSMC's third-quarter net income. The foundry reported quarterly revenue of NT$1.49 trillion ($46.6 billion) and net profit of NT$763.06 billion, alongside a cash dividend of NT$9.0 per share. The board also cleared the formation of a wholly owned investment unit capitalized at up to $500 million. That entity will oversee strategic holdings across the semiconductor supply chain, according to the board disclosure. The transaction places the world's dominant contract chipmaker onto the shareholder registers of both leading frontier model creators. Until now, TSMC participated in generative software entirely as an upstream component fabricator. Anthropic disclosed the foundry's participation on Nov. 10 in an amended Form S-1 registration statement filed with the US Securities and Exchange Commission. The Claude developer set an indicative price range of $70 to $78 per share. The share offering could raise up to $64.35 billion in public proceeds. That would establish a market capitalization of approximately $1.4 trillion across fully diluted shares, ranking behind only SpaceX among history's largest corporate market debuts. TSMC is entering through a concurrent $26 billion private placement of Class N common stock. The placement closes immediately after the public offering and delivers shares to participants at the final offering price without underwriting discounts. The private placement aligns TSMC with its own biggest silicon customers. Nvidia and Google committed $10 billion each to the placement, while Advanced Micro Devices pledged $2.5 billion, and Broadcom and Micron Technology committed $1 billion apiece. Nvidia and AMD account for the vast majority of graphic accelerator demand flowing into TSMC's 4-nanometer and 3-nanometer fabrication lines. Both designers build their competing hardware platforms around TSMC's proprietary Chip-on-Wafer-on-Substrate packaging technology, known as CoWoS. Anthropic explicitly identified foundry concentration as an operating bottleneck in its filing. The company stated that TSMC has at times been unable to satisfy total market demand, creating delays in obtaining computing hardware. Securing equity participation gives the foundry direct insight into software roadmaps that determine accelerator design cycles. Frontier labs are transitioning from training standard neural networks to deploying reasoning architectures that consume substantially higher memory bandwidth. For OpenAI, the $500 million commitment gives TSMC equity exposure to the ChatGPT developer as it prepares custom silicon projects. OpenAI Group PBC continues to evaluate internal processor designs to diversify procurement beyond merchant accelerators. The twin investments effectively construct a circular financial network around TSMC's fabrication facilities. Capital invested into Anthropic and OpenAI funds data-center compute contracts, which flow directly back into accelerator purchases from Nvidia, AMD and custom design houses. Those chip vendors subsequently order wafers and advanced packaging services from TSMC. The foundry holds a near-monopoly on the production of high-performance logic silicon and advanced packaging required for generative model training. TSMC's newly approved $40.93 billion capital appropriation directly targets the capacity pinches restraining those customers. The budget expands 2-nanometer fabrication lines in Baoshan and Kaohsiung and accelerates construction of domestic CoWoS packaging facilities. Nvidia relies entirely on TSMC to fabricate its Blackwell and Hopper processors. AMD similarly contracts TSMC for all production of its Instinct MI300 and MI350 accelerator series, leaving both dependent on Taiwanese factory throughput. The mutual reliance means model builders cannot source replacement silicon if Taiwanese lines stumble. By joining the cap tables of Anthropic and OpenAI, TSMC links foundry scheduling directly to the two software labs directing global compute consumption. The equity purchases also provide the foundry with defensive alignment against rival fabricators. Samsung Electronics and Intel have sought to win artificial intelligence accelerator contracts by offering turnkey packaging and foundry bundles at discounted rates. Yet neither challenger has matched TSMC's yield consistency on multi-die packages, where silicon failure renders expensive adjacent memory stacks unusable. TSMC's deep customer ties and capital reserves continue to lock customers into its manufacturing ecosystem. The public board filing does not state whether the equity stakes include guaranteed wafer allocations or preferential packaging queues for either lab. TSMC has also not published the execution date or implied equity percentage for the OpenAI agreement. Anthropic plans to conclude its roadshow and price its common shares on Nov. 18, 2026. The stock is scheduled to begin public trading on the Nasdaq Global Select Market on Nov. 19 under the ticker ANT. ## Primary sources 1. sec.gov 2. tsmc.com 3. choicestock.co.kr --- Cite as: East Asia Brief, "TSMC approves $1 billion equity stakes in OpenAI and Anthropic," November 10, 2026. https://eastasiabrief.com/semiconductors/tsmc-approves-1-billion-equity-stakes-openai-anthropic-1313
