The Sixth C: A New Framework for Understanding Arizona's AI Economy

By Brian McCarthy

This is the first in a three-part series based on the State of AI in Arizona 2026 report recently released by AI48. The goal of the series is to take several of the report's core findings and examine what they mean for Arizona's technology, investment, academic, and policy communities. This first article focuses on a core idea that emerged from the research and became one of the report's central frameworks: Arizona should embrace a Sixth C — Compute.

Arizona's main economic drivers have historically been known as the Five Cs (Cattle, Copper, Citrus, Cotton, and Climate). While that legacy still matters today, the report argues that the state's next economic chapter will be shaped in part by the physical and institutional systems and human innovations that support artificial intelligence, advanced computing, and digital infrastructure at deployment scale. Compute is not a narrow reference to chips or servers alone, rather it is a broader way to describe the full stack of capabilities that increasingly underpins economic growth in the AI era.

In Arizona, that stack starts with a physical technology foundation of semiconductors and advanced packaging, where we are a national leader anchored by major investments from TSMC, Intel, and Amkor. Tucson's optics and photonics ecosystem adds another important aspect to this layer, particularly as high-bandwidth optical interconnects become more relevant to next-generation AI infrastructure.

Arizona also ranks among the top North American markets for data center development, with strong momentum in large-scale capacity and pipeline growth, primarily due to the availability of developable land, pragmatic utility planning, customer-funded power models, and increasingly water-efficient cooling approaches. And while the debate on data centers sometimes invites controversy, there is no denying their importance in the AI stack and their growing role as a defining economic driver.

But Compute in the Arizona context is much broader than hardware. It includes infrastructure components like power, land, and water strategy, the innovation ecosystem, university research and workforce development, public policy and economic development, and the practical industry environments where AI systems are deployed.

One of the report's main conclusions is that Arizona's advantage comes from the combination of these factors rather than from any single asset. That is part of what makes the Sixth C framework useful: it captures the broader enabling environment instead of one or two components.

Long-term value for Arizona will depend on how effectively the state translates these assets into applied innovation, company creation, talent retention, and practical deployment across industries such as manufacturing, logistics, healthcare, government, aerospace, and defense.

From my own view, the Sixth C gives Arizona a more accurate way to describe what is taking shape here. It reflects the reality that AI is not a hardware-only, software-only, or even technology-only story. It is also an infrastructure story, a deployment story, a talent story, and an economic development story. The state's opportunity is not simply to host pieces of the AI economy, but to understand the full stack of compute and connect our multiple existing strengths in ways that I believe no other state can.

That leads directly to the next question: if Arizona has the foundations of compute, how does it turn those separate strengths into a more durable advantage worthy of a Sixth C? That is the focus of the second article in this series, which looks at why Arizona's long-term role will depend not just on capacity, but on connecting them into a comprehensive full stack that provides benefits across the state.
