What's happening

Taiwan Semiconductor Manufacturing Company reported second-quarter revenue growth of 36% year-over-year, reaching a record high, with earnings rising 58.4% YoY and net profit expected to increase 58.8% YoY. June alone contributed T$442.68 billion in revenue, representing a 67.9% year-over-year surge and a 6.2% month-over-month increase. TSMC, the world's largest dedicated semiconductor foundry with a market capitalization of approximately $2.18 trillion and a workforce of 76,907, manufactures advanced chips on 3nm and 5nm process nodes for clients including NVIDIA and AMD without designing its own products. Alongside the earnings results, TSMC announced an additional $100 billion commitment to U.S. manufacturing investment, reinforcing its expansion posture amid sustained AI infrastructure buildout.

The VanEck SMHX ETF, which tracks fabless semiconductor designers and explicitly excludes foundries such as TSMC, closed at $60.27 on July 6, 2026, before declining 2.97% to $58.48 in a subsequent single-day move. Despite that pullback, the fund had gained 58.48% year-to-date through July 6 and approximately 89.57% to 90% over the trailing twelve months. SMHX's holdings include NVIDIA, AMD, and Qualcomm — companies that design chips but rely on TSMC's fabrication capacity to bring those designs to market. TSMC's own shares have advanced between 49.42% and 57% year-to-date, reflecting the same AI demand environment that has propelled the fabless segment.

Why it matters for markets

TSMC's Q2 results provide a direct demand-side signal for the fabless semiconductor industry: the foundry's 36% revenue growth and 58.4% earnings growth are largely attributable to orders from AI chip designers, making TSMC's financial performance a proxy for the volume of advanced silicon being consumed across the AI supply chain. For SMHX holders, the ETF's 58.48% YTD gain through July 6 reflects the degree to which that demand has translated into valuation expansion for companies like NVIDIA — which carries a market capitalization of $5.15 trillion and trailing revenue of $253.49 billion — and AMD, with a market cap of $862.82 billion. The structural decision to exclude TSMC from SMHX has not insulated the fund from foundry dynamics; rather, it has concentrated exposure to the designers whose order volumes are driving TSMC's record results.

The additional $100 billion U.S. investment pledge from TSMC carries implications for the domestic semiconductor supply chain, potentially affecting the cost structure and geographic risk profile of fabless companies that source manufacturing from TSMC's facilities. TSMC's trailing twelve-month share appreciation of 94.49% and SMHX's corresponding 89.57%–90% gain over the same period suggest the two segments have moved in close correlation despite the ETF's deliberate foundry exclusion. The June revenue figure of T$442.68 billion, up 67.9% year-over-year, indicates that the demand acceleration is not confined to a single quarter but has been building through the first half of 2026.

The divergence in valuation multiples across the sector is also notable. NVIDIA trades at a price-to-earnings ratio of 32.6, while AMD's P/E stands at 175.2 and TSMC's at 36.5, reflecting different market assessments of growth trajectories and earnings bases. These multiples, set against the backdrop of TSMC's record quarterly results, frame the stakes for upcoming earnings reports from the fabless companies that depend on TSMC's capacity.

Sectors and assets to watch

The primary tickers directly implicated by TSMC's Q2 results are NVIDIA (NVDA), AMD, and TSMC itself (TSM). NVIDIA, with a 52-week range of $164.07 to $236.54 and a current price of $212.50, is among TSMC's largest customers for advanced AI accelerators including the H100 and A100 product lines. AMD, trading at $529.14 within a 52-week range of $149.22 to $584.73, relies on TSMC's leading-edge nodes for its EPYC data center processors and Instinct AI accelerators. Both companies are core holdings of SMHX, meaning their individual performance trajectories are central to the ETF's continued year-to-date momentum. Qualcomm, also named as an SMHX holding, represents additional fabless exposure within the fund.

Beyond the named tickers, TSMC's $100 billion U.S. investment commitment has potential implications for the broader domestic semiconductor ecosystem, including equipment suppliers and materials companies that would support expanded U.S. fabrication capacity. The 67.9% year-over-year jump in TSMC's June revenue also warrants attention from investors tracking AI infrastructure spending, as it suggests that hyperscaler and data center capital expenditure programs are translating into tangible wafer demand at the foundry level — a dynamic that flows upstream to chip designers and downstream to system integrators.

What to watch next

Key forward-looking developments include TSMC's formal Q2 earnings call, where management guidance for the second half of 2026 will be closely parsed for signals on advanced node capacity utilization and pricing. NVIDIA and AMD are both scheduled to report quarterly results in the coming weeks, and their revenue figures and data center segment disclosures will indicate whether the demand volumes implied by TSMC's record output are translating into equivalent top-line growth for the fabless designers. The trajectory of SMHX relative to TSMC's own share performance will also be worth monitoring, as the ETF's 58.48% YTD gain and TSMC's 49%–57% advance have tracked closely despite the fund's structural exclusion of the foundry — any divergence could signal a rotation in how markets are pricing foundry versus fabless exposure within the AI semiconductor theme.
