The global semiconductor foundry market has posted staggering growth for the second quarter of 2025, reaching a monumental $41.7 billion in revenue. The driving force behind this surge is none other than Taiwan Semiconductor Manufacturing Company (TSMC), which has achieved a landmark 70 percent share of the entire market, further cementing its position as the industry's indispensable giant.
The latest data, which underscores the relentless demand for advanced chips powering everything from AI to next-generation consumer electronics, paints a picture of a market where the gap between the top player and the chasing pack is widening into a chasm.
A Market Booming on the Back of AI and High-Performance Computing
Industry analysts point to an insatiable appetite for high-performance computing (HPC) and artificial intelligence accelerators as the primary engine for this growth. As companies worldwide race to develop and deploy AI models, the need for the most advanced manufacturing processes—specifically the 3nm and 5nm nodes—has skyrocketed.
"TSMC has become the unequivocal winner of the AI boom," said a lead semiconductor analyst. "Their competitors simply lack the capacity and technological maturity at the most advanced nodes to meet the demand from clients like NVIDIA, AMD, and Apple. This quarter's numbers are a direct reflection of that concentration of innovation and manufacturing capability."
The broader industry growth, while impressive, is not uniform. While the overall foundry revenue is up, it is heavily skewed toward the leading edge. This trend is detailed in the comprehensive report from TrendForce, which breaks down the market share and growth drivers for each major player. According to the latest analysis from TrendForce, the competitive landscape saw some shifts, but none that challenged TSMC's overwhelming lead.
The Chasing Pack: Samsung and Intel Foundry Services
Behind TSMC, Samsung Foundry maintained its position as a distant second. The South Korean conglomerate has been aggressively pursuing clients for its own 3nm GAA (Gate-All-Around) process, aiming to carve out a larger piece of the lucrative AI chip market. However, yield challenges and a smaller portfolio of entrenched clients have prevented it from closing the gap with TSMC in the short term.
Intel Foundry Services (IFS) continues its long-term strategy to become a major foundry player, leveraging its advanced packaging technologies and planned geographic expansion into the U.S. and Europe. While it showed incremental growth, its market share remains a fraction of TSMC's, highlighting the immense challenge of converting a historically internal manufacturing operation into a successful third-party foundry business.
What This Means for the Future and Global Supply Chains
TSMC's unprecedented 70% market share raises both admiration and concerns within the industry. On one hand, it demonstrates the success of its pure-play foundry model and relentless execution. On the other, it highlights the extreme concentration of advanced semiconductor manufacturing in a single company and a single geographic region.
This concentration continues to fuel massive government initiatives, like the U.S. CHIPS Act and Europe's Chips Act, which aim to subsidize and build a more geographically diverse and resilient supply chain. However, as this quarter's results prove, building capacity that can compete with TSMC's scale and technological prowess is a multi-year, multi-billion dollar endeavor with no guaranteed success.
For now, the industry remains heavily reliant on TSMC. Any major disruption at the company, whether from geopolitical tensions, natural disasters, or other black swan events, would send immediate shockwaves through the global technology sector. As demand for AI chips continues to outstrip supply, TSMC's record-breaking market share is a testament to its critical role in powering the modern digital world.
