Global Foundry Market Hit Record $320 Billion in 2025 — TSMC Pulled Sharply Ahead
The global semiconductor foundry market reached a record $320 billion in revenues in 2025, with TSMC growing 36% year-over-year while the rest of the foundry market managed just 8% growth collectively. The data, freshly published by Tom's Hardware, underscores how TSMC's dominance is not merely holding steady but actively widening — putting rivals further behind in the race for leading-edge process technology.
Bipartisan U.S. Bill Seeks to Crack Down on Chip Equipment Exports to China
U.S. lawmakers unveiled legislation this week designed to severely restrict sales of advanced semiconductor machinery to China used in AI systems — explicitly calling on allies including the Netherlands and Japan to align with the new controls. The bill, described by Bloomberg as a significant escalation in the tech war, would extend the reach of U.S. controls beyond American companies to foreign firms using American technology, echoing the Foreign Direct Product Rule framework.
A companion bill was simultaneously introduced in the House, per NBC News, with the explicit goal of banning the sale of "key AI chipmaking machines" to China in a bipartisan show of legislative momentum rarely seen on technology trade policy.
Samsung Emerges as Default Alternative as TSMC Sells Out Through 2028
With TSMC's 2nm and next-generation process capacity fully booked — including its forthcoming Arizona fab before it has even broken ground on production — Samsung Foundry is now widely being discussed as the only credible alternative for AI chip designers locked out of TSMC slots. Reports from Korea Herald and SamMobile confirm Samsung is actively fielding inquiries from customers who previously preferred TSMC, positioning it for potentially transformative orders in 2026–2028.
Manufacturing & Supply Chain
TSMC Advanced Capacity Booked Through 2028 — Including Arizona TSMC's most advanced nodes (3nm and 2nm) are fully subscribed through 2028, a situation driven primarily by insatiable AI chip demand from Nvidia, Apple, and other hyperscale customers. Critically, TSMC's next-generation Arizona fab — still under construction — is reportedly already fully booked before it produces a single wafer. This creates an extraordinary multi-year supply bottleneck affecting the entire AI accelerator ecosystem.
Samsung Foundry Positioned at 2nm as Overflow Valve Samsung's 2nm process node has become the focal point for customers unable to secure TSMC capacity. According to Chosun (English), Samsung foundry's 2nm is the strongest contender to absorb overflow demand, though the company still faces yield and customer trust challenges it must overcome to capitalize on the opening.
Global Foundry Market Structure: TSMC Controls 70% of Foundry Revenue New data published this week by The Motley Fool confirms TSMC's stranglehold at approximately 70% of global foundry revenue, with Samsung a distant second at roughly 7%. The chasm between first and second place is structurally significant: it means Samsung cannot simply absorb TSMC overflow — it would need to execute flawlessly on yield and capacity ramp to matter at scale.
Geopolitics & Trade Policy
New U.S. Legislation Targets Allied Chip Equipment Firms The Bloomberg-reported bill introduced April 2 represents a significant escalation: it would extend U.S. export controls to allied nations — specifically targeting ASML (Netherlands) and Tokyo Electron (Japan) — preventing them from selling key lithography and deposition tools to China even when those tools contain no American components. If enacted, this would represent the most sweeping extraterritorial application of chip export controls since the Entity List was first weaponized against Huawei.
House Bill Specifically Targets AI Chipmaking Machinery The parallel House bill focuses specifically on AI-related semiconductor manufacturing equipment, signaling Congress's intent to go beyond chip-level export controls and target the upstream tooling layer. This is a conceptual evolution in U.S. export control strategy: rather than restricting chips after they are made, the goal is to prevent China from acquiring the means of production entirely.
25% Tariff on AI Chips Remains in Effect The Trump administration's January 2026 executive action imposing a 25% tariff on imports of advanced AI chips — including Nvidia's H200 and AMD's MI325X — continues to reshape procurement patterns, forcing cloud providers and AI infrastructure builders to reassess supply chains and absorb elevated costs. This tariff layer, stacked on top of the TSMC supply crunch, compounds pricing pressure on AI infrastructure buildout.
Market Moves & Earnings
Semiconductor Industry on Track for $1 Trillion in Sales in 2026 The Semiconductor Industry Association (SIA) confirmed in February that the global chip industry hit $791.7 billion in revenues in 2025 — a 25.6% year-over-year surge — and is now on track to breach $1 trillion in annual sales in 2026. The AI infrastructure wave is the primary driver, with data-processing silicon projected to exceed half of total semiconductor revenue before year-end.
AI Accelerator Revenue Expected to Reach $300–350 Billion by 2029–2030 Analyst firm Creative Strategies projects AI accelerator chips — which accounted for under $100 billion in 2024 — to surge to the $300–350 billion range by 2029–2030, cementing AI silicon as the dominant growth driver of the entire semiconductor industry for the rest of the decade.
Deep Dive: The TSMC Capacity Crunch and Its Strategic Fallout
The most consequential story in semiconductors right now is not a product launch or earnings beat — it is a structural capacity crisis that is reshaping the entire competitive landscape. TSMC's advanced node capacity is fully booked through 2028, including the next-generation Arizona fab that has not yet produced commercial wafers. This is an extraordinary situation: customers are locking in capacity for a fab that does not yet exist, years in advance, because no alternative can match TSMC's yield, density, and reliability at the frontier.
The strategic implications cascade in every direction. For Samsung, the TSMC crunch is a genuine opportunity — perhaps the best opening the Korean giant has seen in a decade. Samsung Foundry has long struggled to attract top-tier customers at leading-edge nodes, hampered by yield concerns and a reputation for inconsistency relative to TSMC. But when the world's premier foundry is simply unavailable, customers must choose between waiting years or qualifying a second source. Samsung is aggressively positioning its 2nm process as that second source, reportedly fielding conversations with major AI chip designers who previously considered TSMC-only strategies.
For Intel, the calculus is more complex. Intel Foundry Services (IFS) theoretically benefits from TSMC scarcity too, but Intel must first prove that its 18A process node delivers competitive yields and performance before major fabless customers take the plunge. Intel's execution on its internal roadmap — particularly its own chip products at 18A — will be the most closely watched signal of IFS's readiness to serve external AI customers. The window created by TSMC's supply crunch will not stay open indefinitely.
For China's domestic fabs — SMIC chief among them — the new legislative push targeting chip equipment exports to allies represents a ceiling on their ambitions. SMIC has shown it can manufacture at 7nm-class process nodes using older equipment, but the pathway to 5nm, 3nm, and below depends on equipment that new U.S. legislation would explicitly deny. The bipartisan bill targeting allied equipment suppliers like ASML and Tokyo Electron could freeze Chinese foundry progress at its current level for years, fundamentally limiting the competitive threat from China's domestic AI chip ecosystem. The battle for advanced semiconductor manufacturing has never been more geopolitically explicit.
What to Watch Next Week
- TSMC Monthly Revenue Report (April): TSMC typically releases monthly revenue data in the first two weeks of each month; April figures will give the first real-time read on whether AI demand is sustaining or showing any signs of softening.
- Congressional Hearing on Chip Equipment Export Controls: Following the introduction of both House and Senate bills targeting chip equipment exports to China, expect committee hearings that could draw testimony from ASML, Tokyo Electron, and U.S. chip equipment leaders; the allied coordination dimension will be central.
- Samsung Foundry Customer Announcements: Any public confirmation of new AI chip customers qualifying Samsung's 2nm process would be a major market signal — watch for announcements from Nvidia, AMD, or Qualcomm.
- Intel 18A Yield Update: Intel's next investor day or technology disclosure could include yield data on the 18A node, which is pivotal for Intel Foundry's credibility with external AI chip customers evaluating alternatives to TSMC.
