Warren Buffett bets US$5 billion on chipmaking with new stake in TSMC
- Assuming Buffett bought TSMC’s ADRs at the average price for the third quarter, the stake would have cost him US$5.1 billion
- TSMC has emerged as a strategically vital player at a time when the US and China have clashed over leadership in the global technology industry

Warren Buffett’s Berkshire Hathaway took a stake of about US$5 billion in Taiwan Semiconductor Manufacturing Co (TSMC), disclosing its holding in the world’s leading chip maker as part of its portfolio changes in the last quarter.
The Omaha-based conglomerate acquired about 60 million American depository receipts in TSMC in the three months ended September, it said in a filing. The Taiwanese company produces semiconductors for clients like Nvidia and Qualcomm, and is the exclusive supplier of Apple’s custom silicon chips. Apple remains the most valuable single holding in Berkshire’s portfolio.
Assuming Buffett bought TSMC’s ADRs at the average price for the third quarter, the stake would have cost him US$5.1 billion. They currently trade at US$72.80. TSMC’s shares rose as much as 5.1 per cent in Taiwan after the disclosure.
The 92-year-old Buffett long shied away from the tech industry, making the case that he did not want to invest in businesses that he did not fully understand. That stance changed in recent years, however, and he has dedicated an increasing proportion of his company’s investments to the tech sector.
Chip manufacturing is one segment that promises sustained growth over the coming years because it is essential to the expansion of nascent industries, including self-driving and electric vehicles (EVs), artificial intelligence and connected home applications. Expansion of cloud computing operations, like that of Amazon Web Services, also promises to bring in more orders for silicon that goes into vast data centres.
TSMC, which has taken over from Intel as the firm advancing the cutting edge of chip production, has also emerged as a strategically vital player at a time when the US and China have clashed over leadership in the global technology industry. Taiwan’s most valuable company has the manufacturing prowess to make the world’s most advanced chips, instrumental to advancing every nation’s future commercial industries like EVs and AI but also feeding their military and cyberdefence ambitions.
The US has imposed elevated sanctions on high-end chips produced for Chinese customers specifically to forestall them making their way into the hands of the Chinese military.
