Taiwan Semiconductor Manufacturing Company TSM, or TSMC, and GlobalFoundries GFS are two prominent players in the highly competitive foundry segment of the semiconductor industry. TSMC helped establish the pure-play foundry business model, focusing solely on making chips designed by its customers. A majority of its revenues come from wafer fabrication, while packaging and testing, mask making, design and royalty income make up the rest.
On the other hand, GFS is a scaled foundry that serves a broad range of end markets, including automotive, communications infrastructure and data centers, smart mobile devices, home and industrial Internet of Things (IoT). The company specializes in essential chip technologies across digital, analog, mixed-signal, RF, ultra-low-power and embedded memory.
Over the past 12 months, TSMC shares have surged 81.3%, while GFS has gained 48.9%.Â

Mordor Intelligence projects the foundry market to reach $184.78 billion in 2026, up from $171.72 billion in 2025 and expand at a 7.61% CAGR through 2031. Against this backdrop, let’s analyze which stock makes the stronger investment case. Â
The Case for TSMC
The company is consistently gaining from strong demand for its leading-edge process technologies. In the second quarter of 2026, revenues increased 33.7% year over year. TSMC’s July revenue report further reflected this momentum, with revenues rising 44.7% year over year. The AI boom continues to drive the need for more computation, supporting the robust demand for leading-edge silicon. TSMC is also seeing a strong outlook from its customers, including major cloud service providers, strengthening its view of a multi-year AI opportunity. With its technology advantages and broad customer base, management expects full-year 2026 revenue growth to be slightly above 40% year over year in U.S. dollar terms.
TSMC is also making progress with its 2-nanometer (N2) ramp-up, which entered high-volume manufacturing in the fourth quarter of 2025 with good yield. Production is now ramping up in phases at Hsinchu and Kaohsiung, supported by demand from smartphones and HPC/AI applications. That said, the steep ramp-up is expected to dilute gross margin by about 3-4 percentage points in the second half of the year.
At the same time, the company continues to execute its global plan to add three more 3-nanometer (N3) fabs — one each in Taiwan, Arizona and Japan — to support its robust multiyear demand pipeline for N3 technologies. It is also increasing mature-node capacity in higher-value areas, such as through JASM Fab 1 in Japan for CMOS image sensor applications and ESMC in Germany for automotive and industrial applications.
The company ended the second quarter with $110 billion in cash and marketable securities, while cash from operations generated in the quarter was nearly TWD 783 billion. TSMC is also increasing its 2026 cash dividend to TWD 24 per share, up 33% from the 2025 levels. The company expects cash dividends per share to continue increasing in 2027.
The Case for GFS
GlobalFoundries delivered $1.79 billion in revenues in the second quarter of 2026, which rose 6% year over year and exceeded the high end of its guidance range. Gross margin expanded nearly 500 basis points, helped by improved structural costs, manufacturing productivity and growth in value-accretive secular end markets.
Technology Services is gaining traction as more design wins convert into revenues and customer partnerships expand. Following the MIPS and Synopsys ARC processor IP Solutions business acquisitions, GlobalFoundries lifted its 2026 Technology Services revenue outlook to $100-$120 million from $60-$100 million, with gross margin expected to be significantly above corporate targets.
Among end markets, Communications Infrastructure and Data Center is a strong contributor, with demand for silicon photonics and silicon germanium (SiGe) offerings driving more than 60% year-over-year revenue growth in the second quarter. GlobalFoundries secured multiple new SiGe TIA and driver design wins across networking customers and also closed a first-of-a-kind design win for smart power stage gate drivers on its BCD platform.
Recently, it also entered into a letter of intent with the U.S. Department of Commerce for a $300 million award aimed at advancing next-generation silicon photonics technologies in the United States.
Solid demand for applications across AI-enabled image processing, health care wearables and next-generation MCUs for edge AI compute drove IoT revenue growth to its fastest year-over-year level since 2022. GlobusFoundries landed three strategic chiplet design wins with Lockheed Martin across its FinFET and FDX platforms and expanded its Microchip relationship through a FinFET design win. That said, Smart Mobile Devices are projected to decline by a low-teens percentage in 2026, as memory pricing and related shortages weigh on industry forecasts.
GFS also made progress in quantum, AI data-center networking and power, as well as IP, software and custom silicon during the quarter. In July, the company paid its first quarterly cash dividend of $0.12 per share, signaling confidence in future cash generation.

Endnote
TSMC continues to benefit from sustained demand for its leading-edge technologies. Its N2 technology is also moving through a significant production ramp-up and is expected to lift revenues further in the coming quarters. The company is also expanding N3 and mature-node capacity to support customer demand. GlobalFoundries delivered a solid second quarter, aided by higher revenues and stronger margins. The company is gaining momentum in Technology Services, alongside strong demand in Communications Infrastructure and Data Center and IoT end markets. However, Smart Mobile Devices faces a weaker outlook in 2026.
On the dividend front, TSMC is raising its payout, while GFS has paid its first quarterly dividend in the quarter. TSMC shares have outperformed GFS over the past year and trade at a lower earnings multiple. Taking all into account, TSM appears to be the stronger choice for investment today.
TSM sports a Zacks Rank #1 (Strong Buy), while GFS carries a Zacks Rank #3 (Hold) at present. You can see the complete list of today’s Zacks #1 Rank stocks here.
