Anthropic flags TSMC concentration risk in IPO filing, says Taiwan disruption could hit chip supply for years
Anthropic told the U.S. Securities and Exchange Commission in its S-1 filing on Oct. 26 that the world’s advanced chip supply is heavily concentrated in Taiwan and largely produced by Taiwan Semiconductor Manufacturing Co. The company said a military conflict, blockade, natural disaster, infrastructure outage, or trade restriction affecting Taiwan could severely disrupt global access to advanced chips, with the fallout potentially lasting for years because replacement fabs take time to build and qualify. The filing also said capacity expansion outside Taiwan remains at an early stage and may not be enough in the foreseeable future to materially reduce concentration risk. Anthropic added that TSMC has previously been unable to fully meet demand for advanced chips, leaving the company at times without enough supply. Bloomberg separately reported that TSMC has committed $265 billion to advanced semiconductor facilities in Arizona and is considering a new production site in Texas, though most of its operations and supply chain remain in Taiwan. Anthropic also identified high-bandwidth memory supply as another constraint, naming SK Hynix, Samsung Electronics, and Micron Technology as key producers.
