Tsmc Shatters Records As Global Semiconductor Foundry Market Reaches Historic 320 Billion Milestone

The semiconductor foundry market experienced significant growth in 2025, with global industry revenue reaching a record $320 billion. Taiwan Semiconductor Manufacturing Company (TSMC), the largest pure-play foundry, dominated the market, accounting for 38% of total revenue and growing 36% year-over-year.

TSMC’s focus on advanced process technologies has been crucial to its success. The company’s earnings data show that nodes 7nm and below accounted for 74% of TSMC’s wafer revenue in Q4 2025, with 3nm contributing 24% and 5nm responsible for 36%. These nodes are at the foundation of high-performance computing and AI applications, making them highly sought after by customers. No other foundry has competitive volume at equivalent nodes, with Samsung’s market share dipping to 7.7% in Q1 2025.

The lack of competition at leading-edge nodes is largely due to TSMC’s investment in process technology. The company has consistently upgraded its manufacturing capabilities, allowing it to produce high-quality wafers with yields above 90%. In contrast, Samsung’s sub-5nm yields are not competitive enough to absorb large orders, forcing the company to source components from other foundries.

TSMC’s ability to command higher prices for its wafers is another key factor contributing to its success. The company has been able to do this due to its strong relationships with customers and its ability to offer high-quality products at competitive prices. TSMC’s average selling price (ASP) increased by 15.9% annually from 2019 through 2025, outpacing production cost growth.

TSMC’s vertical integration into advanced packaging has also played a crucial role in its success. The company has expanded its capacity for CoWoS (chip-on-wafer packaging) to roughly double its previous level, with plans to increase it further by the end of 2025. This expansion is largely driven by demand from AI and high-performance computing applications, where advanced packaging is becoming increasingly important.

The growth of TSMC’s advanced packaging business has created a second revenue stream that competitors can only partially capture at this time. The company’s OSAT (original equipment manufacturer) segment grew 10% year-over-year in 2025, with ASE and SPIL becoming the second- and third-largest players in the Foundry 2.0 market behind TSMC.

While Samsung’s 2nm ramp may begin attracting external customers if yields stabilize, TSMC remains confident in its position at the center of the AI chip supply chain. The company has a pre-committed customer base that is committed to years of advanced packaging capacity, providing a stable demand baseline. Additionally, TSMC’s expansion into new facilities and its plans for 2nm production ramping will further reinforce its market dominance.

TSMC’s unmatched concentration of leading-edge node volume, compounding wafer price increases, and vertical integration into advanced packaging have made it the most successful foundry in 2025. While competitors are working to catch up, TSMC remains well-positioned to maintain its market leadership for the foreseeable future.
