Taiwan Semiconductor Manufacturing reported strong Q2 earnings with 36% revenue growth year over year and 77% earnings per share growth, and signaled that chip demand will remain robust through 2029 or 2030. The company is investing another $100 billion(約16兆円) in Arizona facilities, suggesting confidence in sustained demand from the AI computing buildout. This outlook makes Nvidia and Broadcom attractive as well, since both stand to benefit from continued semiconductor demand.

Taiwan Semiconductor Manufacturing reported Q2 revenue growth of 36% year over year (in New Taiwan Dollars) and earnings per share growth of 77%, and announced plans to invest another $100 billion(約16兆円) in Arizona fabrication facilities. CEO C.C. Wei stated that strong chip demand will persist through 2029 or 2030.
Why it matters
TSMC's outlook signals the AI hardware buildout is far from complete, which means sustained demand for chips from companies like Nvidia and Broadcom. For investors, this suggests these three semiconductor stocks remain undervalued despite recent gains—TSMC is down about 15% from its all-time high, Nvidia more than 10%, and Broadcom more than 20%.
What to watch
Broadcom's custom AI chip division is expected to generate $100 billion(約16兆円) in AI semiconductor revenue next year, up from $10.8 billion(約1.7兆円) last quarter—a figure that signals whether the company can deliver the explosive growth priced into its forward valuation of 19 times FY 2027 earnings.
Taiwan Semiconductor Manufacturing released earnings showing that the artificial intelligence hardware buildout remains robust and far from completion. In the second quarter, TSMC's revenue grew 36% year over year (in New Taiwan Dollars), while earnings per share jumped 77%, reflecting improving operating leverage as the company scales production. Most significantly, TSMC announced plans to invest another $100 billion(約16兆円) in its Arizona fabrication facilities—a bold commitment that signals confidence in sustained chip demand. CEO C.C. Wei reinforced this outlook by stating that strong chip demand will persist through 2029 or 2030, effectively locking in a multi-year growth horizon.
The stock market's initial reaction was muted; despite these strong results and rosy guidance, TSMC has fallen about 15% from its all-time high. This disconnect between fundamentals and valuation has created a contrarian opportunity for individual investors. As the only chip manufacturer with sufficient capacity and advanced-enough technology to support a major AI computing buildout, TSMC is positioned to remain a core supplier throughout the cycle.
Nvidia and Broadcom are primed to benefit from this extended demand environment. Nvidia faces 82% estimated revenue growth for the remainder of the current fiscal year and 42% growth next year according to Wall Street analysts—yet the stock remains down more than 10% from its all-time high. When valued against next year's earnings, analysts contend the company looks underpriced and could rally by year end. Broadcom, hit harder with a decline of more than 20% from its peak, faces an even more dramatic inflection. The company's custom AI chip business is expected to generate $100 billion(約16兆円) in AI semiconductor revenue in the coming year, a sevenfold increase from the $10.8 billion(約1.7兆円) in revenue that division posted last quarter. This explosive growth potential explains why Broadcom trades at 19 times forward FY 2027 earnings—a valuation that reflects a fundamental transformation in the business mix. Together, the three stocks signal that the semiconductor cycle underpinning artificial intelligence infrastructure remains in early innings, offering investors multiple entry points at reduced valuations.
TSMC's second-quarter results have reignited conviction in the multi-year semiconductor cycle tied to artificial intelligence infrastructure. The 36% revenue growth and 77% earnings per share growth underscore the company's pricing power and operational efficiency gains as it captures the bulk of advanced chip production for AI workloads. Critically, the company's willingness to invest another $100 billion(約16兆円) in Arizona capacity—a massive commitment—signals that management expects demand to remain strong well into the next decade. CEO C.C. Wei's explicit guidance that chip demand will persist through 2029 or 2030 effectively rules out an imminent slowdown in the AI buildout, a concern that had weighed on valuations earlier in the year.
This outlook has immediate implications for Nvidia and Broadcom. Nvidia's forecast for 82% revenue growth for the remainder of the fiscal year and 42% growth next year is underpinned by TSMC's continued capacity and reliability as a supplier. Broadcom, meanwhile, is undergoing a more dramatic transformation: its custom AI chip business is expected to generate $100 billion(約16兆円) in revenue next year, up from $10.8 billion(約1.7兆円) last quarter—a trajectory that positions the company as a direct beneficiary of intensifying AI chip demand. Despite recent sell-offs across all three names, the constellation of strong guidance, massive capital investment, and forward earnings estimates suggests the market has not fully priced in the length and breadth of the AI cycle.
