The artificial intelligence supply chain represents one of the most complex and concentrated technological ecosystems in modern industry. From the first transistor created at Bell Telephone Laboratories in 1948 to today's frontier AI models requiring billions of parameters and specialized computing infrastructure, the evolution spans seven decades of compounding innovation. Understanding this supply chain—from lithography equipment manufacturers to cloud providers deploying AI capabilities—reveals the interconnected dependencies that enable current AI capabilities and the vulnerabilities that could constrain future development.
The transistor, invented in 1948 by physicists John Bardeen, Walter Brattain, and William Shockley, replaced vacuum tubes with smaller, more energy-efficient semiconductor devices that amplified and switched electronic signals. This breakthrough won them the 1956 Nobel Prize in Physics and laid the foundation for increasingly powerful digital systems that would eventually enable artificial intelligence.
The same year, Dartmouth College held a conference establishing artificial intelligence as a distinct academic discipline. Organized by John McCarthy, Marvin Minsky, Nathaniel Rochester, and Claude Shannon, the conference proposed that every aspect of learning or intelligence could be precisely described such that machines could simulate it. Initial optimism faced challenges through periods of skepticism known as AI winters, but the semiconductor industry and AI field developed deeply interconnected relationships over time.
The evolution of semiconductors allowed AI models to progress from simple rule-based systems to deep learning models with billions of parameters. In 2006, Microsoft researchers recognized that convolutional neural networks designed in the 1990s for image processing could train more efficiently by parallelizing computation using Nvidia graphics processing units originally designed for video games. The AlexNet algorithm won Stanford's image classification competition in 2012 using this approach.
The introduction of transformers in 2017 by Google Brain researchers enabled natural language processing tasks—sequential by nature—to parallelize using hardware accelerators, creating breakthroughs in machine learning capabilities.
State-of-the-art AI development requires three primary inputs: data, algorithms, and computing resources. The rise of deep learning since the early 2010s has been driven by the availability of large datasets, advances in neural network architectures, and substantial improvements in computational power.
Large amounts of data are necessary for training frontier models. AI labs use large public datasets such as Common Crawl and Wikipedia, supplemented by proprietary datasets for niche applications. Data quality proves critical—supervised learning approaches require meticulously labeled datasets, while self-supervised learning depends on human labeling at different stages. Data availability has increased exponentially, enabling more complex and accurate models.
Algorithmic efficiency in neural networks doubles every 9 months, according to research by Erdil and Beriglu, advancing much faster than Moore's Law. Current models achieve similar performance to older versions with less compute and data. Both algorithms and data are non-rival but excludable—multiple users can utilize them simultaneously, yet access can be restricted.
Computing resources remain essential for training and deploying AI models. Specialized hardware, including AI accelerators—chips optimized for AI computations—dominate this category. Graphics processing units represent the most widely used accelerators. Field-programmable gate arrays can be reprogrammed for specific computational tasks after manufacture. Application-specific integrated circuits, such as Google's Tensor Processing Units, are designed for specific functions.
Research from Sevilla shows that compute required by frontier AI systems has increased by a factor of 4.2 annually since 2010. Unlike data and algorithms, computing resources are rivalrous—one entity's use of a chip prevents others from accessing it. This characteristic positions computing as a key element in AI governance proposals.

The AI supply chain spans from upstream lithography equipment to downstream AI laboratories, characterized by global reach, complexity, concentration, high fixed costs, and significant research and development investments. Key stages include lithography companies building fabrication machines, chip fabricators producing semiconductors, chip designers creating specifications, cloud providers offering infrastructure, and AI laboratories developing frontier models.
AI labs, including OpenAI, Google DeepMind, Anthropic, and xAI design, train, and deploy frontier models pursuing artificial general intelligence. Microsoft, Meta, Apple, and Mistral develop large foundation models. Major tech companies, including Google, Amazon, and Microsoft, offer cloud services enabling developers to access AI tools, frameworks, and APIs without extensive infrastructure investment.
The semiconductor industry encompasses chip design and manufacturing, as well as the machines used to produce them. The process starts with extracting silicon from sand and purifying it through specialized chemical methods. Silicon enables the production of transistors—small electronic components that represent binary code and form the core of computer systems. Chips are manufactured from larger wafers designed to fit maximum transistor density.
The industry originated in Silicon Valley during the 1960s. Gordon Moore predicted that transistor count on chips would double every two years—the forecast known as Moore's Law. Companies focused on reducing node size, referring to manufacturing processes and feature dimensions typically related to transistor gate size. Smaller nodes allow more transistors to be packed together, improving performance and efficiency.
A significant shift occurred in 1987 with the founding of TSMC by Morris Chang, in collaboration with the Taiwanese government and Philips. TSMC specializes in manufacturing, enabling the prevalence of fabless companies focusing on design while outsourcing fabrication. Semiconductor manufacturing now concentrates in East Asia, including Taiwan, Japan, South Korea, and China.
ASML, based in the Netherlands, achieved a de facto monopoly in extreme ultraviolet lithography technology introduced in the early 2000s, which is essential for manufacturing the most advanced chips. This concentration illustrates how technological advancement can create market dominance, shaping industry dynamics.
Nvidia's GPUs dominate as hardware accelerators in AI. Google offers Tensor Processing Units as ASICs available only through cloud services. The industry increasingly creates chips specialized for either training or deployment tasks, optimized for specific stages of AI model lifecycles.
This geographic and technological concentration creates supply chain vulnerabilities—disruptions at a single point, such as TSMC fabrication facilities or ASML lithography equipment, could constrain global AI development capabilities.
AI models exhibit strong relationships between performance and factors including model size, data volume, and compute usage. Performance follows power-law relationships with each scale factor—number of parameters, dataset size, and compute utilized. The relationship between pretraining compute budget and held-out loss typically follows log-log patterns. Larger models increasingly dominate due to observed associations between training performance and practical capabilities.
Beyond the technical triad of data, algorithms, and compute, talent serves as a major bottleneck. Technical expertise concentrates in key innovation hotspots as highlighted by economic literature on technological clusters. This talent concentration reinforces geographic advantages certain regions maintain in AI development capabilities.
The AI supply chain evolved from fundamental semiconductor physics breakthroughs into a complex, globally distributed yet highly concentrated ecosystem. Understanding this evolution reveals the interdependencies between lithography equipment, chip fabrication, design capabilities, cloud infrastructure, and AI laboratories. Geographic concentration in East Asia for manufacturing and talent clustering in specific innovation centers creates both efficiencies through specialization and vulnerabilities through single points of failure. As AI capabilities continue advancing, the supply chain structure will significantly influence which organizations and nations maintain competitive advantages in frontier model development.
