Our thesis
AI infrastructure capex is the largest concentrated build-out in technology history. The durable economic value forms in layers, and each layer has a different risk and ownership profile. Foundational chokepoints (EUV lithography, leading-edge foundry, GPU compute, high-bandwidth memory, datacentre power and cooling) are the deepest moats and where we anchor public-equity exposure. The platform layer (NVIDIA's CUDA stack, hyperscaler custom silicon, networking) is where competitive dynamics actually decide. The frontier-lab layer (OpenAI, Anthropic, xAI, Mistral, SSI, DeepSeek) is where most of the demand originates but where almost nothing is publicly investable. The application layer is the spillover thesis and the reason this worldview cross-references Defense, Biotech, Fintech, and SpaceTech.
NVIDIA is the most concentrated single bet in AI infrastructure, and the platform-layer call we have to make explicitly. The CUDA software stack creates switching costs that compounded over fifteen years; every framework, every researcher, every inference runtime is calibrated to it. The Mellanox acquisition extended the moat to multi-rack training clusters via InfiniBand and Spectrum-X. The bull thesis is durable platform pricing power on the demand explosion ahead. The bear thesis is customer concentration (three or four hyperscalers absorb the majority of revenue), the rise of hyperscaler-internal custom silicon (Broadcom-fabricated AWS Trainium, Google TPU, Microsoft Maia), and AMD's MI accelerators taking share where workloads tolerate switching. Blackwell shipments versus HBM3e availability is the gating ratio we monitor for the next twelve months of the call.
Frontier labs are the demand engine but mostly not publicly investable. OpenAI's $40B-plus raise, Anthropic's multi-round $20B+ stack, xAI's $6B round, and the next wave (SSI, DeepSeek, Mistral, plus China incumbents) determine the capex landing at NVIDIA, TSMC, and ASML. We watch them, we cannot hold them. Public exposure to the frontier-lab thesis lives through proxies: Microsoft's OpenAI position and exclusive Azure compute relationship, Alphabet's Anthropic stake plus internal Gemini, Amazon's Anthropic investment plus Trainium build-out, Meta's Llama open-weights strategy and internal capex draw. Each funding round and capability release is a leading indicator for the chokepoint thesis below it, and a stress test of whether public-side multiples are sustainable.
Edge sources we lean on: (1) hyperscaler capex guidance and the capex-to-cloud-revenue ratio as the bull/bear pivot for the entire stack; (2) ASML book-to-bill and high-NA EUV tool shipment cadence; (3) TSMC N3 and N2 capacity utilisation and pricing discipline; (4) NVIDIA customer concentration disclosures and Blackwell-vs-HBM shipment commentary; (5) HBM availability and pricing (SK Hynix is the real bottleneck more than any GPU); (6) frontier-lab funding rounds and capability releases as demand-side leading indicators; (7) Chinese substitution velocity (Huawei Ascend, SMIC yield) as the tail risk; (8) 13F flow into Coatue, Tiger Global, ARK on the AI stack.
Sub-themes we track
NVIDIA platform
CUDA software stack plus Mellanox / Spectrum-X networking. The platform-layer call. Bull case durable pricing power; bear case is customer concentration, hyperscaler custom silicon, and AMD MI gains.
EUV / lithography
ASML monopoly. Multi-decade durable; the deepest moat in technology. Watch book-to-bill and high-NA EUV shipment cadence.
Leading-edge foundry
TSMC structural at N3 and N2; Samsung and Intel as wildcards with execution risk. Pricing discipline at the frontier is the bull/bear pivot.
Frontier labs (proxies)
OpenAI (via MSFT), Anthropic (via GOOGL + AMZN), xAI, Mistral, SSI, DeepSeek. Mostly private. Tracked for demand-side signal; held via cloud-platform proxies.
Hyperscaler custom silicon
Broadcom-fabricated AWS Trainium and Inferentia, Google TPU, Microsoft Maia. Compresses NVIDIA share where workloads tolerate it. Broadcom and Marvell are the public expressions.
Memory and HBM
SK Hynix dominates HBM3e supply; Micron the credible second source; Samsung struggling to qualify. HBM is often the real bottleneck, not GPU silicon.
AI datacentre stack
Power, cooling, networking infrastructure beneath the GPUs. Vertiv, Eaton, Schneider, Arista. The unsexy compounders under the capex curve.
Inference economics
Token cost trajectory across open and closed models. Where margins actually land when the training arms race normalises.
Vertical AI applications
Defence AI (Palantir, Anduril), AI-bio (Recursion, Schrödinger), enterprise infrastructure. Cross-vertical with Defense and Biotech focus areas.
Chinese substitution
Huawei Ascend, SMIC, domestic memory. Tail risk to the moat thesis; even partial substitution compresses Western premium.
