Entity Index

Anthropic

Frontier lab behind the Claude model family, backed by Google and Amazon. A top-tier compute buyer: leases exclusive capacity at xAI's Colossus 1 for inference at $1.25B/month and anchors Amazon's Project Rainier campus buildout.

ByteDance

TikTok's parent and one of the world's largest GPU buyers, procuring through every channel export controls allow — a major hidden variable in global accelerator demand.

Cohere

Enterprise-focused model company (Toronto) betting on private/on-prem deployment rather than frontier-scale training — a different, smaller compute-demand profile.

DeepSeek

Chinese lab whose efficient training runs periodically shock the market's assumptions about how much compute frontier capability requires — the standing bear case for GPU demand.

Mistral AI

France's frontier lab and Europe's flagship AI-sovereignty bet, training open-weight and commercial models on European data center capacity.

OpenAI

The frontier lab behind ChatGPT and the GPT model line, and the anchor of the Stargate data center program — a capital project denominated in hundreds of billions. Its compute appetite sets the demand curve the entire infrastructure buildout is racing to meet.

Perplexity

AI search company whose inference-heavy product makes it a bellwether for the economics of serving (rather than training) models at consumer scale.

Safe Superintelligence

Ilya Sutskever's lab, raised at multibillion valuations with no product — a pure bet that frontier training compute converts to capability. A large, quiet GPU buyer.

Scale AI

Data-labeling and evaluation platform threaded through frontier training pipelines; part-acquired by Meta in 2025 in a talent-and-data deal.

Thinking Machines Lab

Mira Murati's post-OpenAI lab; one of the best-funded startups ever at founding, and another claimant on scarce frontier training capacity.

xAI

Musk's AI lab, folded into SpaceX in the February 2026 all-stock merger. Built the Colossus campus in Memphis — the largest single-site AI installation — pioneering generation-first buildouts with on-site gas turbines; now leases capacity to Google and Anthropic while burning billions per quarter training Grok.

AlibabaBABA

China's largest cloud and its Qwen open-weight models anchor the domestic AI stack; its accelerator procurement is a proxy for how export controls actually bind.

AmazonAMZN

AWS is the largest cloud on Earth and its Trainium/Inferentia silicon is the second-biggest custom-accelerator program after Google's TPUs. Anthropic's primary compute partner (Project Rainier), an SMR investor (X-energy), and a top-three data center capex spender globally.

AppleAAPL

The conspicuous holdout of the capex race: runs comparatively modest 'Private Cloud Compute' on its own silicon and leans on partners for frontier models — a standing counter-bet that device-edge inference beats data center scale.

BaiduBIDU

China's search giant and earliest LLM mover (Ernie); operates AI cloud capacity on a mix of domestic and grandfathered NVIDIA silicon.

GoogleGOOGL

Alphabet's Google is one of the three global hyperscalers and the most vertically integrated AI operator: it designs its own TPU accelerators (the only at-scale alternative to NVIDIA silicon), trains the Gemini frontier models, and runs Google Cloud. On the infrastructure ledger it is both builder and renter — signing SMR offtakes with Kairos Power, researching orbital compute constellations, and paying ~$920M/month for external capacity at xAI's Colossus 2, all while its DeepMind unit sets the research agenda much of the buildout chases.

IBMIBM

Enterprise AI and hybrid-cloud player; matters to the buildout mainly through consulting-led deployment, its Granite models, and quantum-computing capex.

MetaMETA

The most aggressive capex story in AI: $37.2B (2024) → $69.6B (2025) → ~$135B guided for 2026, building the gigawatt-class Prometheus and Hyperion campuses while committing up to $48B to rent external capacity from CoreWeave and Nebius. Now preparing to sell surplus compute and models as a fourth hyperscale cloud. Trains the open-weight Llama family; designs its own MTIA inference silicon.

MicrosoftMSFT

TencentTCEHY

Chinese hyperscaler (WeChat, games, cloud) and major domestic AI infrastructure spender under export-control constraints.

AMDAMD

The credible second source for AI accelerators: Instinct MI-series GPUs win frontier-lab and hyperscaler deals on memory capacity and price, while EPYC CPUs anchor the server sockets around them. The perennial question is software — ROCm versus CUDA.

Analog DevicesADI

High-performance analog for power, sensing, and connectivity across data center and grid infrastructure.

Vertically stacked DRAM feeding AI accelerators — produced at volume by only SK hynix, Samsung, and Micron. Sold out years ahead; above 30% of DRAM industry revenue; the truest chokepoint in the accelerator supply chain.

InfiniBand

The low-latency cluster fabric NVIDIA acquired with Mellanox; now defending share against Ultra Ethernet in AI back-end networks.

NVIDIA Blackwell

NVIDIA's 2024–2026 accelerator generation (GB200/GB300 NVL72 racks) — the platform that pushed racks past 120 kW and made liquid cooling standard.

NVIDIA Vera Rubin

NVIDIA's next platform generation; the CoreWeave and Nebius mega-contracts with Meta are among its first at-scale bookings.

NVLink

NVIDIA's proprietary GPU-to-GPU interconnect — the moat that turns chips into racks and racks into single giant accelerators.

Small Modular Reactors

Factory-built reactors (NuScale, X-energy, Kairos, Oklo designs) that hyperscalers are underwriting as the 2030s answer to firm carbon-free power.

Colossus

xAI's Memphis-area campus: ~2 GW and 555,000 GPUs across Colossus 1 and 2 — the largest single-site AI installation, partly leased to Anthropic (all of Colossus 1) and Google (Colossus 2 capacity).

Fairwater

Microsoft's frontier-training campus line (Wisconsin flagship) — purpose-built halls it calls the world's most powerful AI data centers.

Hyperion

Meta's Louisiana mega-campus, pitched at 5 GW at full build — the largest announced single-company AI site in the West, powered through Entergy.

Palisades

Michigan reactor that became America's first successful nuclear restart (Holtec, 2025) — proof the restart playbook works beyond TMI.

Project Rainier

Amazon's Indiana mega-campus dedicated to Anthropic's training — hundreds of thousands of Trainium chips across a multi-gigawatt site.

Prometheus

Meta's ~1 GW Ohio campus — the first of its named gigawatt-class AI sites, brought up with on-site gas turbines.

Stargate Abilene

Flagship site of the OpenAI-led Stargate program in Abilene, Texas — Crusoe-built, Oracle-operated, gigawatt-class, with dedicated on-site gas generation.

Three Mile Island Unit 1

Retired Pennsylvania reactor being restarted as the Crane Clean Energy Center under Constellation's 20-year, ~835 MW PPA with Microsoft — the template for nuclear-backed AI power.

Vogtle

Georgia's four-reactor plant; units 3 & 4 are the only new U.S. reactors this century and the benchmark for what new nuclear actually costs.

BIS

Commerce's Bureau of Industry and Security — writes the export-control rules that decide which chips can ship where, redrawing the global compute map with each revision.

CAISO

California's grid operator — high prices and slow interconnection push AI builders elsewhere, making it the counterfactual.

Department of Energy

Funds advanced reactors, HALEU, and grid programs, and designates federal sites for AI data centers — industrial policy's operating arm.

ERCOT

Texas's grid operator — the epicenter of AI load growth, fielding large-load interconnection requests measured in tens of gigawatts against a market design built for scarcity pricing.

FCC

Licenses the satellite constellations (including SpaceX's million-satellite orbital data center application) and the spectrum the frontier bids depend on.

FERC

Federal energy regulator deciding the co-location wars — whether data centers can plug straight into power plants — and every transmission cost-allocation fight behind AI load.

MISO

Midcontinent grid operator absorbing data center load across 15 states with a strained interconnection queue.

NRC

Nuclear Regulatory Commission — the licensing gate every restart, SMR, and uprate must clear; its timelines are the nuclear-AI trade's real constraint.

PJM

The 13-state eastern grid operator containing Data Center Alley; its capacity auctions repricing 10x on AI load is the clearest market signal of the power squeeze.
