AI Infrastructure Sector Overview — US & Hong Kong Markets

Prepared: May 29, 2026

Coverage: US-listed and HK-listed AI infrastructure, hardware, cloud, and software

Format: Parallel coverage (US + HK side-by-side), institutional briefing, ~15 pages

Executive Summary

The AI infrastructure buildout has matured into a generational capital supercycle. The five major US hyperscalers (Amazon, Microsoft, Alphabet, Meta, Oracle) will commit a combined ~$600–710B of capex in CY2026 — roughly +36% YoY — of which ~75% is directly AI-attributable. NVIDIA's Q1 FY2027 (April-quarter) revenue hit $81.6B (+85% YoY), with data center alone at $75.2B. Hyperscaler backlog data is unprecedented: Microsoft RPO $625B (>100% YoY), Oracle RPO $553B (+325%), Google cloud backlog >$460B.

In Hong Kong, Q1 2026 China tech earnings revealed bifurcation. Mega-cap internets posted modest beats with margin compression from AI capex (Tencent's underlying margin ex-AI expanded 310bps; Baidu's core AI-powered business hit +49% YoY at RMB 13.6B, GPU cloud +184%). Hardware names had record quarters — Lenovo crossed US$83B FY2026 revenue with AI revenue +84% YoY, and ASMPT bookings +71.6% YoY (a 4-year high). HKEX is in an AI-IPO supercycle: Q1 2026 raised HK$109.9B (5-year high); MiniMax (0100 HK) IPO'd at HK$165 in January 2026 and trades at ~HK$837 today, ~5x.

Key tensions: (1) ~$700B of infra capex vs. only ~$100B in disclosed AI revenue creates a monetization timing gap; (2) DeepSeek V3.2 / Qwen 3 / Llama 4 have permanently re-rated open-source baseline downward, compressing model-API margins; (3) power and grid interconnection — not chips — is the binding constraint in 2026 (Eaton DC orders +240% YoY, 228 GW backlog ≈ 12 years).

US AI mega-caps trade at elevated but supportable multiples (Nasdaq 100 trailing P/E ~33x; NVIDIA NTM P/E ~41x with PEG ~1.0x). Hang Seng Tech trades at a structural ~30–40% discount to US peers and underperformed YTD 2026 (HSTECH futures imply ~-15% YTD), creating a relative-value opportunity.

6. Key Themes for May 2026

6.1 The Capex Cycle — Still Accelerating, Not Peaking

Verdict: 2026 is peak GROWTH rate (+36%), not peak LEVEL. Bank of America projects $641B (2026) → $739B (2027). JPMorgan explicitly rejects "peak capex 2026" thesis. Morgan Stanley sees capex peaking near $1T around 2028.

Current AI capex is ~0.8% of global GDP vs. ~1.5%+ in prior tech cycles at peak — implying room to run, but ROI visibility remains the key risk.

6.2 Inference Inflection — 2026 Is the Crossover

Deloitte: inference reaches ~⅔ of AI compute in 2026 (up from ~50% in 2025)
CoreWeave Q1 2026: inference already >50% of consumed compute
IDC: DRAM market triples to >$400B in 2026, driven by HBM and DDR for AI

Implication: Memory (HBM, DDR5), networking optics (Marvell), and ASICs (Broadcom) are the more leveraged plays vs. pure GPU exposure.

6.3 ASIC vs. Merchant Silicon

NVIDIA retains training dominance: ~80% share; CUDA moat intact through Blackwell/Rubin
ASIC winning at hyperscaler inference: Google TPU, AWS Trainium/Inferentia, Meta MTIA, OpenAI/Broadcom 10GW system
Broadcom AI revenue $8.4B Q1 (+106%) vs. NVIDIA DC $75.2B (+92%) — Broadcom growing faster off smaller base

6.4 Power as Binding Constraint

Global DC electricity demand: ~460 TWh (2022) → ~1,000 TWh by 2026 (≈ Japan's total)
Grid interconnect timelines: 4–10 years
Eaton DC backlog: 228 GW = ~12 years at 2025 build rates
Vertiv Americas DC +53%; CapEx +208% YoY
Microsoft, Amazon, Google all signing nuclear PPAs (Constellation, Helion fusion, TerraPower)

6.5 DeepSeek Aftermath — Permanently Re-Rated Mid-Tier

DeepSeek V3.2: $0.14/M input vs. GPT-5.4 $2.50/M = ~18x cheaper at near-frontier quality
Inference cost declining ~10x/yr (a16z); ~50–200x/yr in some benchmarks (Epoch AI)
BUT: enterprise AI spend still +320% in 2 years ($1.2M → $7M avg) because Jevons paradox + agentic 10–20 LLM calls/task
Net: Model API margins compressed; total compute demand still rising

6.6 China-US Tech Decoupling

US export controls cap NVIDIA China upside; China responds with domestic chips (Huawei Ascend, Cambricon)
Creates duplicated, fragmented stacks → net incremental capex globally
China AI capex "has not truly begun" at scale (JPMorgan) — a future upside lever
Key risk to monitor: further EDA/foundry restrictions

6.7 Sovereign AI

US Stargate: ~$500B / 10 GW announced; 7 GW already committed across 5 sites; Oracle/NVIDIA/Broadcom beneficiaries
Saudi/UAE/India/EU all running national AI compute programs
Net effect: Adds incremental demand outside US hyperscalers; benefits NVIDIA exports + local DC builders

6.8 Hong Kong AI IPO Wave

HKEX Q1 2026: HK$109.9B raised (5-year high)
AI-specific IPOs: MiniMax (Jan 2026, +400% from IPO), Z.ai, Biren Technology
Pipeline: ~20 AI value-chain companies disclosed
Southbound Stock Connect: ADT HK$104B (Feb 2026); structurally supportive

7. Sector Valuation Context

7.1 Where Multiples Sit vs. History

Index/Sector	Current	5/10-Yr Avg	Read
Nasdaq 100 trailing P/E	~33.4x	27.3–33.1x range	At/above upper bound
Nasdaq 100 forward P/E	~26.6x	~22x (10-yr)	~20% premium
S&P 500 IT Sector forward	~30x	—	vs. ~55x at 2000 dot-com peak
Hang Seng Tech	n/a (data gap)	Below 5-yr avg	Structural discount

Bottom line: US AI complex elevated but supportable on earnings (Mag 7 60–80% profit growth Q1 2026). HK Tech offers structural discount but with regulatory/geopolitical premium baked in.

7.2 Bubble Check vs. 2000

Factor	2000	2026
Revenue at peak comp	Most no revenue	NVDA $80B/qtr, MSFT AI $37B ARR, CoreWeave $99B backlog
Cash flow	Negative	Positive at all mega-caps
Forward P/E peak	~55x	~30x
Verdict	Bubble	Elevated, not bubble

Pockets of excess: AMD trailing P/E ~164x (cited); Arm ~358x; some IPO-era AI plays. Mid-cap SaaS already corrected — EV/revenue compressed 26–29% in Q1 2026.

8. Investment Implications

8.1 Where to Lean

Segment	View	Why
AI power/infra (Eaton, Vertiv, Lenovo)	Constructive	Multi-year backlog, binding constraint, less narrative-dependent
Memory (Micron)	Constructive	HBM upcycle, +196% growth, 75% gross margin
ASICs (Broadcom, Marvell)	Constructive	Inference inflection favors custom silicon
HK mega-cap with AI (Baidu, Tencent)	Constructive	Cheapest AI exposure globally; AI revenue inflection
AI revenue-disclosing software (Palantir, Salesforce, ServiceNow)	Selective	Premium multiples but agentic ARR real
Cybersecurity (Zscaler in particular)	Selective	Cheapest growth-adjusted at 11.7x
AI IPO wave HK	Tactical	MiniMax-style speculative — size accordingly
Pure-play AI infra (CoreWeave, Nebius)	Cautious	High beta, debt-financed, not yet profitable

8.2 What to Avoid

C3.ai (-46% revenue YoY despite branding) — cautionary tale
Generic LLM-wrapper SaaS (1–2.5x EV/revenue ceiling)
Legacy SaaS with thin AI moat and weak NRR
Chinese names with high BIOSECURE/regulatory exposure (WuXi Bio cohort)

9. Key Risks

Hyperscaler ROI disappointment in 2H26 / 2027 → multiple compression for entire AI hardware complex
Power/grid stranding — projects without signed PPAs face execution risk
Further US-China escalation (EDA, foundry, ECCN tightening) → supply chain volatility
Open-source acceleration (Qwen 4, Llama 5) further compressing API margins
Anthropic/OpenAI IPO valuation reset — could de-rate AI software comps
Geopolitical — Iran shock recurrence, Taiwan strait, etc.
Talent wage inflation — opex risk underappreciated in capex models

10. Catalysts to Watch (Next 90 Days)

June 2026	NVIDIA Q2 FY2027 earnings (~late Aug); Computex Asia announcements
June FOMC	Possible first cut signaling
