Global Advanced Packaging and HBM Market Outlook to 2032

Executive Summary

Advanced packaging and HBM is the most supply-constrained and most concentrated layer in the AI compute stack. The AI-relevant subset (CoWoS, Foveros, fan-out, EMIB-T, and HBM3 / HBM3E / HBM4) grows from US$22 billion in 2024 to US$265 billion by 2032 at 36% CAGR.

Three forces drive the trajectory. TSMC's CoWoS capacity scales from approximately 35,000 wafers per month (late 2024) to a projected 120,000-130,000 by close of 2026, a 3.4-3.7-fold expansion. NVIDIA has booked over 50% of projected 2026 CoWoS capacity (industry triangulation: 595,000 wafers, 60% of total demand, 510,000 for CoWoS-L). HBM is the most concentrated supply layer in AI infrastructure: SK Hynix at 62% market share (Q2 2025), Micron 21%, Samsung 17%; SK Hynix's 2026 capacity is fully pre-booked by NVIDIA and OpenAI, and 100% of 2026 HBM4 production is sold out through long-term contracts. HBM3E prices were reportedly hiked nearly 20% ahead of the 2026 supply shift.

Market Overview

The AI-relevant advanced packaging and HBM scope captures four flow components: AI-relevant advanced-packaging services (TSMC CoWoS-S/L/R, Intel Foveros family, EMIB-T, Samsung X-Cube, ASE and Amkor 2.5D/3D AI lines), HBM memory revenue (HBM3, HBM3E, HBM4 at SK Hynix, Samsung, Micron), AI-allocated equipment capex at major capital-equipment vendors (ASML, Applied Materials, Tokyo Electron, Onto Innovation), and OSAT and substrate value capture.

The category sits at the intersection of three forces. The AI capex supercycle drives demand: every NVIDIA GB200 / GB300 system requires both CoWoS capacity and HBM memory, and 2025 GB200 NVL72 cabinet shipments of 25,000-35,000 (revised down from initial 50,000-80,000 forecast) reflect supply-side constraint, not demand softness. US-China semiconductor decoupling reshapes equipment supply (BIS export controls October 2022, October 2023, October 2024 versions). And the CHIPS Act NAPMP onshoring effort: US$1.4 billion in finalised awards and Intel's US$7.86 billion CHIPS funding and SK Hynix US$3.87 billion West Lafayette and Amkor US$2 billion Peoria collectively represent approximately US$25-30 billion of US-domestic advanced-packaging-and-HBM capex commitment through 2030.

Geopolitically, Taiwan dominates AI-relevant advanced-packaging capacity at 64% (TSMC CoWoS and ASE OSAT). South Korea dominates HBM at 18% (SK Hynix Icheon and Cheongju, Samsung Cheonan and Hwaseong). The US share grows from 6% in 2024 to approximately 14% by 2030 on CHIPS Act-funded buildout. China remains 18-24 months behind frontier on domestic substitution despite acceleration at JCET, Tongfu, SMIC XDFOI, and CXMT.

Market Size and Growth Outlook

The 2025 single-year 127% growth is the steepest year in the category's history, reflecting both HBM3E transition pricing premium and GB200 / GB300 ramp expansion. From 2026-28 growth moderates to 35-60% as TSMC CoWoS capacity catches up, SK Hynix West Lafayette and Amkor Peoria scale through 2027-29, and HBM4 reaches volume manufacturing.

Market Segmentation

By Packaging Technology

CoWoS-L is the fastest-growing technology, expected to reach 32% by 2032 driven by NVIDIA's Blackwell and Rubin generation roadmap. CoWoS-S compresses from 38% to 24% as the H100/H200 product cycle matures. Intel Foveros expands from 11% to 16% by 2030 as Foveros-R wins cost-optimised AI accelerator programmes and EMIB-T captures HBM-bridge socket.

By HBM Generation

HBM4 is the fastest-growing generation by far, expected to reach 52% by 2030. The HBM3-to-HBM4 transition creates a 24-month pricing-power window for SK Hynix as the first-to-volume HBM4 supplier; Samsung's recovery and Micron's expansion narrow the spread by 2028.

By End-Customer

NVIDIA's 60% share is structurally durable through 2027 because NVIDIA's Rubin (2026), Rubin Ultra (2027), Feynman (2028) roadmap is locked into TSMC CoWoS-L allocation. Hyperscaler in-house ASIC programmes collectively expand from 8% to 18% by 2030 as AWS Trainium, Google TPU, Microsoft MAIA, and Meta MTIA scale.

Trends and Developments

TSMC CoWoS capacity 3.4-3.7-fold expansion

TSMC's CoWoS expansion from approximately 35,000 wafers per month (late 2024) to 120,000-130,000 (end-2026) is the single largest capacity buildout in advanced-packaging history. The Chiayi AP7 plant is central, with multiple expansion phases through 2028. TSMC's December 2025 announcement of an Arizona advanced-packaging facility extends geographic footprint. NVIDIA's reported 510,000-wafer CoWoS-L allocation for 2026 leaves the residual market structurally tight for AMD, hyperscaler ASICs, and emerging entrants.

HBM4 sells out 100% of 2026 capacity

SK Hynix 2026 HBM capacity is fully pre-booked by NVIDIA and OpenAI. Micron HBM capacity sold out through calendar 2026. Samsung's HBM3E NVIDIA approval delays in 2024 cost the company HBM market leadership; Samsung's HBM4 timing (Q3 2025 first products, volume 2026) is the recovery vehicle. Top-5 cell manufacturers (SK Hynix, Samsung, Micron) are joined by emerging Korean and US-domestic capacity through 2027-28.

CHIPS Act NAPMP advanced-packaging onshoring

CHIPS Act NAPMP finalised US$1.4 billion in advanced-packaging awards through January 2025: Natcast Tempe (US$1.1 billion), SK Hynix West Lafayette HBM (US$458 million for US$3.87 billion total), Amkor Peoria AZ (US$407 million for US$2 billion greenfield), Absolics, Entegris, Infinera, GlobalFoundries. Plus Intel's US$7.86 billion CHIPS direct funding. Total US-domestic advanced-packaging-and-HBM commitment exceeds US$25-30 billion through 2030 with capacity ramping 2027-29.

Other relevant developments include CoWoS-S to CoWoS-L transition reshaping hyperscaler procurement, Samsung HBM crisis and recovery trajectory, China domestic-substitution acceleration despite BIS controls, and panel-level packaging (FOPLP) emerging as the next-generation production format from 2027-28. CoWoS-L and HBM3E supply also gatesGB200/GB300 liquid-cooled cabinet shipments, making advanced-packaging capacity the upstream constraint on the entire AI-data-centre buildout.

Competitive Landscape

The category is the most concentrated supply layer in the AI compute stack. Top-3 (TSMC, SK Hynix, and Micron) collectively control 62%; top-5 (adding Samsung Memory and Samsung Foundry) control 74%. Concentration is structurally durable through 2030 because capital intensity, tacit knowledge, and customer-qualification cycles make new entrants impractical without 5-10 year horizons. Natcast at Tempe is the only structurally significant new entrant emerging from CHIPS Act funding, with material AI-relevant operations expected 2027-28.

Key Policies and Regulatory Environment

CHIPS Act and CHIPS NAPMP advanced-packaging programme

US CHIPS Act and Science Act (signed August 9, 2022) authorised US$52.7 billion in semiconductor incentives. The CHIPS NAPMP opened up to US$1.6 billion in advanced-packaging funding competition (October 2024), with US$1.4 billion finalised through January 2025. Anchor awards: Natcast Tempe (US$1.1 billion), Absolics, Entegris, Applied Materials and ASU substrate research, Infinera, GlobalFoundries. Plus separate CHIPS direct-funding awards: SK Hynix West Lafayette IN HBM (US$458 million for US$3.87 billion project), Amkor Peoria AZ (US$407 million for US$2 billion greenfield), Intel direct-funding US$7.86 billion. First material US-domestic advanced-packaging-and-HBM buildout in 30 years.

BIS export controls on advanced-packaging equipment to China

BIS October 2022 final rule (revised October 2023, October 2024) restricts Lam Research, Applied Materials, Tokyo Electron, and ASML deliveries of certain advanced-packaging tools to Chinese OSAT and memory facilities. The May 13, 2025 BIS AI Diffusion Rule rescission did not reverse equipment-side controls. The BIS January 13, 2026 final rule shifted to case-by-case license review for H200 and MI325X exports to mainland China, Hong Kong, Macau.

Other relevant frameworks include the EU Chips Act (€43 billion target investment to double EU semiconductor share by 2030), Korean K-Chips Act tax credits supporting SK Hynix and Samsung domestic and US operations, Taiwan Ministry of Economic Affairs investment incentives for TSMC Chiayi AP7 expansion, Japan METI funding for TSMC Kumamoto JASM advanced-packaging, and India Semiconductor Mission supporting Tata Electronics OSAT entry.

Future Outlook

The AI-relevant advanced packaging and HBM market in 2032 reaches approximately US$265 billion. AI-relevant advanced-packaging services account for 28% of value (US$74 billion) and HBM accounts for 72% (US$191 billion). The structural shift through 2032 is HBM-content-per-AI-system growth from approximately US$10,000 per accelerator in 2024 to US$25,000 per accelerator by 2030.

The competitive landscape concentrates further. Top-3 (TSMC, SK Hynix, and Micron) maintain approximately 60% combined value share through 2030. Top-5 (adding Samsung Memory and Samsung Foundry) holds at approximately 73%. The US share of AI-relevant manufacturing grows from 6% (2024) to 14% by 2030 on CHIPS Act-funded buildout; Taiwan compresses from 64% to 52% as non-Taiwan capacity grows faster off smaller bases.

The biggest risk is a hyperscaler capex pause event in 2027-28. If any of the top-3 hyperscalers (Microsoft, Google, Amazon) materially slows AI capex through a cyclical down-period, advanced-packaging-and-HBM capacity utilisation falls and pricing compresses. Sovereign-AI programmes (Stargate, HUMAIN, Mistral, IndiaAI) provide partial structural offset because sovereign capex is policy-anchored and less cyclical than hyperscaler capex. Secondary risk is HBM supplier qualification failure cascading to AI silicon delivery delays at NVIDIA, AMD, and hyperscaler programmes simultaneously.
