How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The size was built upward from shipment volumes and realised prices for each product type: accelerators, processors and SoCs, networking ASICs, mixed-signal devices and structured ASICs, each priced by process node and packaging class. Non-recurring engineering fees and design-service revenue were added per program, using typical program counts and fee levels by node. The result was then checked against revenue that named suppliers disclose for custom and semi-custom products in their filings and earnings materials. Where the two disagreed, the unit, price or program-count assumption was corrected; disclosed revenue was never averaged in. The inputs that carry the estimate are wafer starts by node, average selling price per die, and the share of cloud capital spending directed to in-house silicon.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Discussions target the people who decide on and deliver custom silicon: silicon and hardware architecture leads at cloud operators, procurement and sourcing managers at device makers, program managers at design-service houses, foundry and advanced-packaging account managers, EDA and IP sales specialists, and export-compliance officers. Sampling emphasises North America for hyperscale demand, Taiwan, South Korea and Japan for foundry, packaging and design-service capacity, and China and Europe for automotive, industrial and domestic-sourcing programs. Conversations focus on program timing, node choice, price per die, design-fee structures and the share of volume moving from merchant parts to custom devices.
Desk research draws on annual and quarterly filings from the listed custom-silicon, foundry and packaging suppliers, including 10-K and 20-F reports and earnings call transcripts; monthly revenue releases from the Taiwan-listed foundries and design-service houses; Semiconductor Industry Association and World Semiconductor Trade Statistics shipment data; customs records under HS codes 8542.31 and 8542.39 for integrated circuits; US Bureau of Industry and Security rules on advanced computing exports; and conference papers from ISSCC and Hot Chips describing announced designs. RISC-V International membership records and EDA vendor filings complement these.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from the number of custom programs entering volume production, the die size and node of each, and the realised price per unit, summed by segment. Cloud capital spending, inference demand growth and the move to smaller nodes and multi-die packages carry the growth. Cryptocurrency mining and consumer volumes are normalised for cyclical swings. For the forecast to hold, hyperscalers must keep shifting a rising share of accelerator spend to in-house designs, leading-edge foundry and packaging capacity must expand in step, and export rules must not close a major demand pool. Prices are assumed to rise with node cost while falling per unit of compute.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Outputs were back-tested by running the same method on 2020 to 2024 and comparing the result with recorded growth in advanced-node foundry revenue and in the disclosed custom-silicon revenue of named suppliers. Segment shifts, such as the rising weight of accelerators and of the newest process nodes, were reviewed with industry experts for plausibility. Sensitivities tested include a change in hyperscaler program counts, a slip of one node generation in volume timing, a swing in average selling price per die, and a tightening of export controls. Segment totals were required to reconcile to the market total in every year examined.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
The estimate is firmest for accelerators, networking ASICs and the largest platform vendors, where supplier disclosures and foundry data allow cross-checks. It is weaker for in-house designs that are never sold to an outside party, for non-recurring fees, and for smaller regional programs, where reporting is thin and counts rely on inference. The base-year total carries a band of plus or minus 15 percent. Revisions would follow from a cut in cloud capital spending, a sharp change in export rules, a foundry capacity shortfall, or a change in how suppliers report custom revenue.
