US — Arizona (APS/SRP) scores 67.2/100 on the Compute Institute Jurisdiction Competitiveness Index (Tier 2, Competitive), ranking #4 of 30 rated jurisdictions with a stable outlook, as of June 15, 2026 under methodology v0. Its strongest dimension is Fiscal & Incentives at 7.7/10; its weakest is Power Availability & Deliverability at 5.1/10. 20 of 22 sub-factors are scored on E1–E2 evidence (data confidence A). The stable outlook is driven by 2 forward-looking signals (-0.09 net points, E3–E4 evidence): AI-specific law in force (E3) and sovereign/anchor capital availability (E3).

  • AI-specific law in force
    E3
    +0.66 pts as of
    “Arizona has no comprehensive AI statute in force; under a stable US federal framework this is permissive-but-predictable rather than uncertain, with no AI-specific restriction on compute/data-center deployment as of mid-2026.”

    Source: Arizona State Legislature / ACC regulatory record (no AI compute statute as of 2026) (www.azleg.gov)

  • Sovereign/anchor capital availability
    E3
    -0.75 pts as of
    “As a US state, Arizona has no sovereign-wealth or government anchor-capital vehicle backing compute infrastructure; financing is private/hyperscaler-led with federal CHIPS support flowing to TSMC rather than to general DC capital, so sovereign anchoring is structurally low.”
