By 2025, TSMC will control about 70% of the worldwide foundry industry thanks to the AI wave
Taiwan Semiconductor Manufacturing Company significantly expanded its dominance in the global contract chip manufacturing market in 2025 as demand for artificial intelligence chips surged worldwide.
According to a report cited by Focus Taiwan and based on data from TrendForce, TSMC generated about $122.54 billion in revenue in 2025. This represented a 36.1% increase compared with the previous year and gave the company a 69.9% share of the global foundry market. The figure marks a sharp increase from its 64.4% market share in 2024.
TSMC’s closest competitor, Samsung Electronics, remained far behind in the rankings. Samsung recorded $12.63 billion in foundry revenue during 2025, representing a 3.9% decline from the previous year and giving it a global market share of about 7.2%.
The report also highlighted TSMC’s performance in the final quarter of 2025. During the October–December period, the company held a 70.4% share of the global foundry market, slightly down from 71.0% in the third quarter. However, quarterly revenue still rose by 2% to $33.72 billion.
While shipment volumes in the fourth quarter declined slightly compared with the previous quarter, strong demand for advanced chips manufactured using TSMC’s 3-nanometer process technology helped increase average selling prices, which in turn boosted revenue.
Overall, the world’s top 10 semiconductor foundry companies generated combined sales of $169.47 billion in 2025, representing a 26.3% increase compared with the previous year.
Among the other major players in the industry, China’s Semiconductor Manufacturing International Corporation ranked third with $9.33 billion in revenue and a 5.32% market share. Taiwan-based United Microelectronics Corporation followed with $7.63 billion in sales and a 4.35% share, while US-based GlobalFoundries recorded $6.79 billion in revenue, accounting for 3.87% of the market.
China’s Huahong Group ranked sixth with $4.50 billion in revenue and a 2.6% share. The rest of the top ten included Tower Semiconductor with $1.57 billion and 0.89% market share, Vanguard International Semiconductor with $1.56 billion and 0.89%, China’s Nexchip Semiconductor with $1.51 billion and 0.86%, and Powerchip Semiconductor Manufacturing Corporation with $1.40 billion and a 0.80% market share.
The surge in revenue across the foundry sector was largely driven by the rapid global expansion of artificial intelligence infrastructure and the rising demand for advanced chips used in data centres and AI applications.
