Global advanced packaging demand is projected to expand from a 2025 base of USD 42.5-45.1 billion to USD 60.9-80.4 billion by 2030, with most forecasts clustering around an 8.6-10.5% CAGR [S1][S7]. Sigmaintell's March 2026 brief goes further, forecasting the global advanced packaging market size at USD 61.8 billion in 2026, a year-on-year jump of roughly 76% over 2024, with the upward price trend expected to hold through end-2026 [S2].
The 2026-2030 window is structurally different from prior cycles: AI accelerator and HBM co-packaging has converted advanced packaging from a back-end finishing step into a primary capacity bottleneck, with lead times on CoWoS and 2.5D/3D lines running above twelve months and order backlogs extending deep into 2027 [S2]. For sourcing teams, the planning horizon is no longer quarterly; it is now aligned to fab construction cycles measured in years.
Demand Forecast Range and Where the Numbers Disagree
Three independent forecasts bracket the 2030 demand picture. PW Consulting projects USD 80.4 billion by 2032 on an 8.6% CAGR from a 2025 base of USD 45.13 billion, with the year-by-year ramp moving USD 49.6 billion (2026), USD 52.42 billion (2027), USD 59.43 billion (2028), USD 62.98 billion (2029), and USD 70.33 billion (2030) [S1]. Virtue Market Research uses a tighter 10.5% CAGR to reach USD 60.96 billion by 2030 from a 2025 base of USD 37 billion [S7]. TrendX Insights, the most aggressive projection, sizes the market at USD 42.47 billion in 2025, hitting USD 133.3 billion by 2030 and USD 261.91 billion by 2034 on a 22.4% CAGR [S4]. The dispersion reflects scope: PW Consulting and Virtue are largely counting 2.5D/3D and flip-chip revenue, while TrendX folds in fan-out, FOPLP, and adjacent advanced substrate flows.
The 2025 inflection is unusually sharp. PW Consulting's data shows 2024 revenue at USD 38.36 billion jumping to USD 45.13 billion in 2025, a 17.65% YoY gain that is the largest step in the entire 2020-2032 series [S1]. TrendX similarly records the 2024-to-2025 transition accelerating to 19.1% YoY growth in 2026, then 29.4% in 2027 as CoWoS-equivalent lines come online [S4]. That double-step is the AI/HBM demand wave materialising in packaging revenue, not a one-off.
Platform Mix: 2.5D/3D vs Flip-Chip vs Fan-Out
2.5D/3D is the dominant revenue platform. By 2025, flip-chip still held the largest type share at 38.2% of the advanced packaging market, but the growth dollars are flowing to 2.5D/3D ICs and integrated fan-out wafer-level packaging for AI accelerator and HBM co-packaging [S1]. Sigmaintell characterises 2.5D/3D as the current mainstream, with FOPLP positioned as the next-generation cost-and-efficiency play that both panel makers and OSATs are pursuing concurrently [S2].
Application mix in 2025 was consumer-electronics-led at 51.5% share by revenue, but the demand-growth tail is HPC, AI accelerators, and automotive ADAS, all of which are migrating to chiplet-based 2.5D architectures [S1][S9]. True Insights segments the 2026 build further by type: FO WLP, FI WLP, flip chip, and 2.5D/3D, with FO WLP gaining the most incremental share on mobile and networking designs [S3].

Capacity Build-Out and the 2027 Supply-Demand Pivot
Global advanced packaging capacity is on track for a 34% CAGR from 2025 to 2030, with the front-loaded phase from 2025 to 2027 running at 47% as new CoWoS-class fabs come online [S2]. Sigmaintell's base case calls for the supply-demand imbalance to persist into H2 2027, then gradually move toward balance as the build-out matures. That pivot point matters for buyers: orders placed in 2026 will still see allocation, while 2028-dated volume is more likely to clear at listed price.
Geographic concentration is heavy. TSMC commands 58% of global advanced packaging capacity, with ASE and Amkor expanding aggressively and mainland Chinese OSATs (JCET, Tongfu, Huatian) climbing fast on HBM packaging and domestic substitution tailwinds [S2]. On the demand side, Asia Pacific was the largest 2025 region at USD 14.2 billion, followed by North America at USD 13.4 billion and Europe at USD 9.0 billion [S1]. For the full vendor-by-vendor map, the Advanced Packaging Market Share 2026 vendor breakdown tracks who is adding CoWoS-equivalent lines and on what timeline.
Application Pull: AI, HPC, Automotive, and Chiplets
AI accelerators and HBM co-packaging are the single largest demand driver. The shift from monolithic SoCs to chiplet-based heterogeneous integration, where logic dies, HBM stacks, and I/O chiplets are assembled in one package, is what makes 2.5D interposer and FO WLP capacity the binding constraint for the entire AI supply chain [S1][S2][S9]. TrendX identifies silicon interposer CoWoS as the lead technology for AI-plus-HBM integration, with integrated fan-out as the high-density mobile and networking follow-on [S4].
Beyond AI, Sigmaintell flags FOPLP as a cost-down path for panel-scale production, while The Insight Partners points to high-performance computing, aerospace and defence, telecommunications, and automotive as the application verticals pulling 2.5D, fan-out, flip chip, and chiplet demand through 2034 [S2][S9]. Automotive in particular is migrating from simple flip-chip packages to multi-die power and sensor modules, raising per-vehicle packaging content. For the silicon-side ramp driving this demand, the Wafer Fab Equipment 2026-2030 outlook maps the front-end capacity that feeds these back-end lines.
Risk Factors and What Could Break the Forecast
Three failure modes sit on top of the consensus. First, the supply-side assumption: if CoWoS-equivalent capacity additions slip beyond 2027, the demand forecast stays intact but deployment slips, and revenue gets pushed to the right rather than the left [S1][S2]. Second, the AI demand assumption: if accelerator unit growth decelerates, the 47% 2025-2027 capacity CAGR overshoots and pricing power collapses before 2030. Third, geopolitical and substrate constraints: glass-core substrate, ABF substrate, and high-end underfill supply remain concentrated, and any disruption there chokes even fabs with installed CoWoS tools.
A secondary risk is scope inflation. TrendX's USD 261.91 billion 2034 figure implies a much broader market definition than the USD 60-80 billion 2030 band from PW Consulting and Virtue, so comparing them head-to-head without scope adjustment overstates the disagreement [S1][S4][S7]. Sourcing teams should anchor on the platform-level demand (2.5D/3D, FO WLP, flip-chip) rather than headline market value when sizing 2027-2030 commitments.
Trackable signals through 2026-2027: TSMC CoWoS monthly wafer output disclosures, ASE and Amkor advanced packaging capex updates, mainland Chinese OSAT HBM-packaging qualification milestones, and any FOPLP yield announcements from panel-fab entrants. The single most important pivot is whether the 2027 supply-demand balance call holds; if it slips into 2028, the 2030 demand totals still arrive, but the path gets noisier.
