Timeline

Chronological developments as recorded by the sources in raw/. Each entry is tagged with its source type — [Primary] (SEC/IR filing), [Tech-report], [Analysis] — because evidence weight varies and, as of the 2026-07-23 compile, the topic finally has first-party company filings alongside the analysis base. Forward-dated entries are clearly separated and are calendar, not events.

2026

July

• Jul 22 — [Primary] Alphabet reports Q2 2026 (8-K Ex-99.1). Total revenue $119.8B (+24%); Google Cloud $24.8B (+82%) at 35.6% op margin; Q2 capex $44.9B outran operating cash flow $39.1B → free cash flow NEGATIVE $(5.9)B, funded by a $49.6B June equity raise + $20.3B senior notes (LT debt doubled to $98.2B). FY capex guide and RPO/backlog absent from the exhibit (call/10-Q items). (Source · Alphabet · Hyperscaler Capex Cycle)
• Jul 22 — [Primary] Tesla reports Q2 2026 (8-K Ex-99.1). Capex $5.79B (+142% YoY) → FCF NEGATIVE $(1.1)B (first since Q1 2024), self-funded by a $1.2B cash drawdown. AI Training Compute table switched units to MW: Cortex 1 >90 MW, Cortex 2 >115 MW (both Production); onsite Texas compute >205 MW combined. In-house Austin semiconductor fab progressing.

• Jul 22 — [Primary] Texas Instruments reports Q2 2026 (8-K Ex-99). Revenue $5.46B beat the $5.00–5.40B guide top; "data center" named a growth leader; Analog +26% YoY. The supply-side mirror: TXN capex falling ($4.94B→$3.31B TTM) as its 300mm wave crests, FCF +271% YoY to 33.6% of revenue (incl. CHIPS Act). (Source · Hyperscaler Capex Cycle)
• Jul 16 — [Analysis] TSMC reports Q2 2026: record revenue NT$1.27T (~$39.62B, +36% YoY), above its $39.0–40.2B guidance band; FY AI-segment growth outlook raised above 40%. CoWoS advanced packaging and the N3 node reported sold out through end-2026, lead times into 2027. (Source · Advanced Packaging Bottleneck)
• Jul 15 — [Tech-report] Lenovo publishes the GB300 NVL72 rack-power spec (vendor product guide): 135 kW rack TDP, up to ~155 kW peak (50V DC), 72 B300 GPUs + 36 Grace CPUs, ~90% liquid / ~10% air cooling. First primary vendor datasheet in the topic — closes the oldest gap (kW/rack). (Source · Rack Power Density)
• Jul 15 — [Analysis] Alphabet Q2 earnings preview published. Frames capex guidance and Google Cloud backlog (~$462B cited) as the watched signals ahead of the Jul-22 print. Expectation only — the actual print (above) resolved capex/Cloud-margin but left the FY guide and RPO open. (Source · Alphabet)
• Jul 10 — [Tech-report] Federal Reserve July 2026 Monetary Policy Report names AI data-center construction as a primary driver of US business fixed investment: +11% annualized in Q1 2026 vs 5.5% in 2025. Net exports subtracted ~0.4pp from GDP on AI-related import content. (Source · Data-Center Construction as a Macro Variable)
• Jul 7 — [Analysis] Samsung releases preliminary Q2 2026 guidance: operating profit ~₩89.4tn (largest ever, ~19x YoY, +56% QoQ) on revenue ~₩171tn, driven by HBM/DRAM tightness. Preliminary only — full results due Jul 30. (Source · HBM & DRAM Supply Tightness)

June

• Jun 25 — [Analysis] ConstructConnect July data-center report: YTD 2026 spending through May of $58.1B — more than 4x the 2025 same-period record. Data centers now >20% of all US nonresidential building starts; power-infrastructure construction forecast +30.8% for 2026. (Source · Data-Center Construction as a Macro Variable)
• Jun 15 — [Analysis] TrendForce: TSMC CoWoS supply-demand gap seen narrowing 20% → ~10% by end-2026. TSMC ~120–140K wafers/mo + OSAT 50–60K = ~200K industry target 2026; >80% CAGR 2022–2027; CoPoS/Feynman 2028–29. The gap narrows but does not close — packaging stays binding through year-end. (Source · Advanced Packaging Bottleneck)
• Jun 11 — [Analysis] Value Add VC capex analysis: big-four 2026 capex put at ~$725B (+77% YoY off a ~$410B 2025 base), split ~50% compute & silicon / ~35% plant / ~15% power & grid. (Source · Hyperscaler Capex Cycle)
• Jun (reported) — [Analysis, superseded] A reported Alphabet equity raise of $84.75B earmarked for AI infrastructure. Superseded 2026-07-23 by the printed $49.6B June equity raise + $20.3B notes in Alphabet's 8-K. (Source)

May

• May 7 — [Primary] CoreWeave reports Q1 2026 (IR release) — the first neocloud primary in the KB. Revenue $2.08B, $99.4B revenue backlog, >3.5 GW contracted power (>1 GW active), Q1 capex $7.70B (~3.7× revenue), net loss $(740)M. Meta named with a $21B commitment — inside CoreWeave's backlog, while Meta is itself a tracked hyperscaler (the double-counting edge). (Source · CoreWeave · Contracted Backlog & RPO)
• May 2 — [Analysis] NextBigFuture / Crusoe capex-per-MW breakdown: AI datacenter ~$59M/MW all-in (~$30M IT + ~$29M infra), ~$15M/MW/yr lease revenue, ~4-yr payback. Single-operator, unit economics as-of ~April 2025 — fills the capex/MW gap. (Source · Capex (commercial))
• May 1 — [Analysis] Carbon Direct: PJM+ERCOT interconnection queue analysis. 3–4-year waits in data-center load zones; >300 GW combined queue across ~1,500 projects. Key reframing: the constraint is queue throughput/deliverability, not raw MW (queue holds enough on paper through 2030). Fills the interconnect-queue gap. (Source · Power: The Binding Constraint)

February

• Feb 12 — [Analysis] Futurum "$690B Infrastructure Sprint": 2026 capex of $660–690B across five companies (big four + Oracle) vs a ~$380B 2025 base; cohort described as supply-constrained rather than demand-constrained; power named the binding deployment constraint. Oracle given its first capex figure in this KB ($50B, +136% YoY; $523B RPO). (Source · Hyperscaler Capex Cycle · Oracle)

January

• Jan 8 — [Analysis] Tesla Cortex 2 documented: a 500MW in-house AI-training datacenter at Giga Texas, targeted operational mid-2026, paired with on-site Megapack storage. (The Jul-22 print later disclosed >115 MW Production for Cortex 2 — the 500MW is a full-buildout envelope, not the printed figure.) (Source · Vertically Integrated Compute)
• Jan 6 — [Analysis] Data Center Knowledge power-bottleneck report: power identified as the binding constraint; 36+ projects representing $162B blocked or delayed; 770-facility pipeline against 1,297 operational; Meta targeting >10GW by end-2026. (Source · Power: The Binding Constraint)
• Jan 5 — [Analysis] Cortex 2 structural beams delivered; installed within two days. (Source)

2025

October

• Oct 28 — [Tech-report] NVIDIA / DOE AI-infrastructure announcement maps the supply chain across DOE supercomputers, neoclouds and power/cooling vendors on GB300 NVL72. Solstice: 100,000 Blackwell GPUs (DOE's largest); Equinox: 10,000 (2026); combined 2,200 exaflops AI. xAI Colossus 2 (Memphis) at 500,000+ GPUs. (Source · Rack Power Density)
• Oct (month) — [Analysis] Microsoft's Atlanta Fairwater site becomes operational. (Source)
