Daily data refresh: the buildout's debt bill, the 66 GW grid number, White House AI meeting, AMD's $8.2B world-model bet
Today's AI-economy briefing, verified and folded into the data. Capex: the buildout is increasingly borrowed — nearly $500B in AI-related debt issued globally by Aug 5, 2026, with debt set to finance 35% of hyperscaler capex in 2027; Goldman now sizes cumulative 2026–31 AI infrastructure capex at ~$7.6T ($765B in 2026 → $1.6T in 2031). Chips: AMD is buying Fei-Fei Li's World Labs for $8.2B in stock (expected close end of 2026, pending approval) — the chip race moves from language models to physical-AI 'world models'; Li becomes AMD EVP & Chief Scientist. Energy: US data-center power demand runs 31 GW (2025) → 41 GW (2026) → 66 GW (2027), hitting 8.5% of peak summer US demand — and only 50–60% of the next two years' planned capacity is expected on time. Labor: the New York Fed finds just 4% of service firms laid anyone off because of AI in six months vs 13% hiring specifically to deploy it; over a third of AI-using firms retrained workers rather than replacing them. Policy: Trump and Speaker Johnson met AI CEOs at the White House today; Google/OpenAI/Anthropic are near launching the SAFA self-regulatory body (pre-release testing, incident reporting, auditor accreditation, targeted late-2026 launch); Florida asked a court to stop OpenAI building new models without outside guardrails.

The AI data center buildout: the power edge
What the buildout is actually doing to power — traced three orders deep, every figure sourced. Not a pitch; the data.
The five largest tech firms spent $400B+ in 2025 and are set to raise it ~75% in 2026 — most of it AI infrastructure. [11] IEA
This spending builds the data centers that consume the electricity above — and drives the price spike below.
From $28.92 to the $333.44 cap in three years; the grid's market watchdog pinned ~63% of the jump on data centers. [12] RTO Insider [5] Utility Dive
This cost gets passed to electricity bills — that's where regular people start paying for the AI buildout.
Thousands to build (~800–1,200 at peak); ~25–50 to run it. Billions of capex, dozens of permanent staff. [8] Brookings
The construction boom is real but temporary — and it pulls workers from housing and other projects that also need them.
