A 2015 estimate by IHS Technology put the economic contribution of semiconductor progress associated with Moore’s Law at at least $3 trillion in incremental global GDP over roughly the previous 20 years, with an upper estimate of about $11 trillion when indirect effects were included. Those figures describe a modeled attribution—not a precise accounting of what Moore’s Law alone caused.
Where the trillion-dollar estimate came from
The headline traces to IHS Technology’s 2015 report, “Celebrating the 50th Anniversary of Moore’s Law,” commissioned and promoted by Intel. Covering approximately 1995–2015, Intel’s summary described at least $3 trillion in incremental global GDP and an upper estimate of roughly $11 trillion once indirect effects were counted. The Congressional Research Service later summarized the study’s estimate of at least $3 trillion in incremental GDP from advanced semiconductors over the preceding two decades.
Coverage of the same analysis sometimes breaks the figures into $3 trillion in direct value plus $9 trillion in indirect value. That presentation does not reconcile neatly with the approximately $11 trillion upper estimate. The figures should be treated as different summaries of the same analysis, not added together or presented as separately verified totals. The original announcement and IHS-derived infographic are available from Moore.org and the infographic; EE Times reports the $3 trillion plus $9 trillion formulation.
The estimate was based on economic and industry data, including multifactor-productivity analysis. IHS also attributed about one percentage point of real GDP growth per year from 1995 through 2011 to Moore’s Law-related activity, describing that contribution as 37% of measured global economic impact in that period. These are IHS’s estimates, not uncontested measurements of causation. The public summaries do not establish enough detail about dollar basis or assumptions to make the totals directly comparable as audited accounts.

What Moore’s Law means—and what it does not
In 1965, Gordon Moore observed and forecast that the number of components that could be placed on an integrated circuit would grow rapidly while the cost per component declined. The familiar later shorthand is that transistor density doubles about every 18 to 24 months, although the cadence has varied and the original formulation was not exactly that rule. Moore’s Law is an industry observation and forecast, not a physical law or a guarantee that improvement will continue at a fixed pace. The Congressional Research Service describes it in this observational sense.
For the economy, transistor counts matter mainly because they have been associated with more computing capability at lower cost. A chip generation can enable faster or more efficient devices, but improvements in software, architecture, memory, networking, manufacturing, and system design also shape what users can do and what it costs.
What the dollars count
GDP measures the value of goods and services produced during a period. It is not the same as wealth, company valuations, household income, or the full value people receive from technology. The IHS estimate’s direct and indirect categories therefore matter:
- Direct economic activity: semiconductor output and related activity, as well as production of computers, phones, networking equipment, and digital infrastructure made viable by better chips.
- Indirect effects: productivity gains, lower computing costs, new businesses and markets, and economic activity enabled when firms and consumers use digital tools.
- Benefits not fully captured in GDP: time saved using search or navigation, the value of free or inexpensive online services, and consumer surplus—the difference between what people would be willing to pay and what they actually pay.
These categories can overlap. For example, a device’s production, the chip inside it, app revenue, and productivity improvements enabled by the device are not automatically separate amounts that can safely be added. GDP also tends to record market production more readily than free services, quality improvements, or saved time.

The broad pathway is: more capable chips make computing cheaper; lower costs encourage wider adoption; businesses and consumers use computing to automate work, communicate, analyze information, and coordinate activity; and those changes support new products, services, and productivity gains. The pathway is plausible, but it is not a single-cause explanation. The Internet needed telecommunications networks and protocols; smartphones required software, standards, and supply chains; cloud services depended on data centers, business investment, and new operating models.
Semiconductor progress helped make personal computers, enterprise software, mobile phones, online commerce, digital advertising, streaming, cloud computing, data centers, and modern AI systems practical at scale. It also supports less visible uses, including industrial controls, medical imaging, scientific simulation, logistics, and financial transactions.
Where the effects have appeared
- Computing and software: lower-cost processing and memory enabled personal computers, servers, increasingly capable applications, and cloud services.
- Communications and consumer electronics: chips support digital switching, routers, wireless networks, smartphones, cameras, and connected devices.
- Manufacturing and logistics: sensors, automation, machine vision, inventory systems, and route optimization can raise throughput or reduce waste.
- Healthcare and research: computing enables medical imaging, genomic analysis, simulation, and data-intensive research. These are important channels, but the IHS estimate does not establish a separate, independently verified dollar total for each one.
- Finance and professional services: digital payments, risk analysis, cybersecurity, and online distribution rely on affordable computing and communications.
- Energy, agriculture, and transportation: modeling, sensing, precision agriculture, navigation, and control systems can improve decisions and operations. EE Times reported a potential estimate of up to 150 billion additional barrels of oil recoverable with advanced digital technology; that is a potential outcome, not a count of barrels actually produced or economic value already realized.
Why the estimate is useful but not definitive
The $3 trillion figure is best read as a historical estimate of direct or minimum incremental GDP contribution; the roughly $11 trillion figure is a broader upper estimate that includes indirect effects. The latter necessarily depends more heavily on how productivity spillovers and related activity are attributed. There is no global accounting ledger that isolates “GDP created by Moore’s Law.”
Several factors complicate attribution:
- Sponsorship: Intel commissioned or promoted the study, and had a commercial interest in the importance of Moore’s Law. Sponsorship does not by itself invalidate the estimate, but it is relevant context.
- Complementary causes: Software, public research, investment, telecommunications, education, business organization, and policy all contributed to digital-era growth.
- Counterfactual uncertainty: The estimate depends on judgments about what economic activity would have occurred with slower semiconductor progress. EE Times describes a scenario in which slower progress would have left technology near late-1990s levels; this is a modelled hypothetical, not an observed alternative history.
- Potential overlap: Direct output and indirect productivity benefits can interact, making double counting a risk unless definitions and methods are clear.
- Uneven gains: Benefits have differed across countries, firms, industries, workers, and consumers, including people with limited connectivity or access to digital tools.
For these reasons, the estimate supports the conclusion that semiconductor progress had economy-wide significance; it does not establish that Moore’s Law alone caused a precisely measurable $11 trillion increase or that the gains were net of social and environmental costs.
What has changed since the estimate
The IHS figures are historical: they were published in 2015 and largely concern the preceding two decades. They are not an updated total through 2026. Nor should the old transistor-density cadence be treated as a complete scorecard for current progress.
Leading-edge manufacturing has become more capital-intensive, requiring expensive equipment, process development, and support for multiple technology generations. The CRS discusses these costs and the limited number of firms able to produce the most advanced chips. Meanwhile, progress increasingly comes from chiplets, advanced packaging, 3D integration, specialized accelerators, memory bandwidth, power management, software optimization, and system-level design. This broader development is sometimes described as “more-than-Moore”: continued gains in computing systems even when classic geometric scaling is harder or more expensive.
That changing mix does not prove Moore’s Law has definitively ended, nor does it mean the old pace continues unchanged. It means any present-day claim about computing’s economic impact needs a current method and a clear definition of what advances it includes.
Economic gains are not the same as net social benefit
The IHS estimate is an economic-impact estimate, not a comprehensive welfare assessment. Semiconductor manufacturing and digital infrastructure also have costs, including energy and water use, e-waste, privacy and cybersecurity risks, labor displacement, digital inequality, and supply-chain fragility. Benefits and costs are distributed unevenly, and the cited total does not establish that the former outweigh the latter.
Verdict
The trillion-dollar claim is credible as an attributed 2015 estimate of the broad economic value enabled by decades of semiconductor progress. Its strongest point is that cheaper, more capable computing spread far beyond chipmakers into productivity, communications, science, and new industries. Its limit is equally important: the $3 trillion and roughly $11 trillion totals are modeled, historical estimates, not proof that Moore’s Law by itself generated a precisely measured sum.
