The Second Ring of the AI Funding Web: Google / Amazon / Anthropic / Meta / Custom Silicon

As of: 2026-06-05. Mapping the second ring of circular AI financing beyond the OpenAI/Microsoft/Nvidia core: the Google–Amazon–Anthropic triangle, Meta's off-balance-sheet datacenter financing, the Broadcom/AMD/Marvell custom-silicon commitments, and the sovereign (Gulf) capital flowing through it all.

All amounts USD. "Circular" = a counterparty is simultaneously an investor in and a vendor to the same company (i.e., money round-trips: a hyperscaler invests cash into Anthropic, which spends that cash buying that same hyperscaler's cloud/chips, which the hyperscaler books as revenue).

1. Google → Anthropic (investor AND vendor — the cleanest circular structure)

Google is simultaneously a top-2 equity investor in Anthropic and Anthropic's single largest compute vendor (TPUs + Google Cloud). Anthropic raises cash from Google, then pays much of it back to Google Cloud for TPU capacity.

Equity / investment

• ~14% stake; >$3B invested cumulatively (pre-2025). SEC filings (revealed via Anthropic-adjacent and Alphabet disclosures, March 2025) showed Google held ~14% of Anthropic, capped at 15%, with no voting rights, board seats, or observer rights. Prior commitments totaled >$3B incl. an additional ~$750M tranche due by Sept 2025. TechCrunch 2025-03-11, Computing 2025
• NEW — up to $40B commitment (April 24, 2026). Google committed $10B in cash now at a $350B valuation (matching Anthropic's Feb 2026 round), plus up to $30B more contingent on Anthropic hitting performance targets, plus a major compute expansion (see below). Bloomberg 2026-04-24, CNBC 2026-04-24, TechCrunch 2026-04-24

Vendor: TPU / Cloud deal

• Oct 23, 2025: "up to one million TPU chips," "well over a gigawatt of capacity coming online in 2026," value "tens of billions of dollars." Builds on the original 2023 Google Cloud partnership. Google Cloud press 2025-10-23, CNBC 2025-10-23, DCD
• April 6–7, 2026: expansion to ~3.5GW of TPU compute access (TPUs co-developed by Broadcom). Analysts estimate Broadcom's revenue from the Anthropic arrangement alone at ~$21B in 2026. CNBC 2026-04-06, TechCrunch 2026-04-07, Bloomberg 2026-04-06
• April 24, 2026: Google Cloud to make 5GW of compute available to Anthropic over five years (bundled with the $40B investment news).

Circular flag: YES. Google invests → Anthropic spends on Google TPUs/Cloud → Google books cloud revenue.

2. Amazon (AWS) → Anthropic (investor AND vendor — Project Rainier)

Like Google, AWS is both Anthropic's largest historical investor and a primary compute vendor (Trainium + AWS cloud).

Equity / investment

• $8B total invested (pre-2026): an initial $1.25B (Sept 2023) + $2.75B (early 2024) + a $4B add-on (Nov 2024), reaching $8B. AWS remains Anthropic's primary cloud/training partner. About Amazon (Nov 2024)
• NEW — additional up to $25B (April 20, 2026): Amazon investing $5B now, up to $20B more in the future, on top of the $8B already invested (i.e., up to ~$33B cumulative). Anthropic 2026-04-20, Capacity

Vendor: Trainium / Project Rainier

• Project Rainier: ~500,000 Trainium2 chips across multiple US data centers, anchored by an ~$11B campus in New Carlisle, Indiana (broke ground Oct 2024; ~30 buildings). Completed/activated late Oct 2025. DCD, SiliconANGLE 2025-10-29
• April 20, 2026 expansion: "up to 5 gigawatts" of capacity, "over one million Trainium2 chips," "nearly 1GW of Trainium2 and Trainium3 capacity coming online by end of 2026." Anthropic committed "more than $100 billion over the next ten years to AWS technologies." Anthropic 2026-04-20

Circular flag: YES. Amazon invests → Anthropic commits $100B+ to AWS → AWS books cloud + chip revenue. Anthropic's full circular position: it raises from Google + Amazon, then spends those proceeds on both companies' clouds/chips.

3. Anthropic valuation / funding (Series G + sovereign money)

• Series G — closed Feb 12, 2026: $30 billion raised at $380B post-money valuation (not the ~$350B / ~$10B initially reported in Jan 2026 — the round expanded ~3x on demand). Anthropic 2026-02-12
• Leads: GIC (Singapore SWF) + Coatue.
• Co-leads: D.E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, MGX (UAE).
• Participants incl. sovereigns/strategics: Fidelity, BlackRock affiliates, Blackstone, Temasek (Singapore), Qatar Investment Authority, Sequoia, General Catalyst, GS Growth, JPMorgan, Morgan Stanley IM, plus Microsoft and NVIDIA.
• Earlier markers: ~$183B valuation (Sept 2025 round); Jan 2026 term sheet of ~$10B at ~$350B led by Coatue + GIC (CNBC 2026-01-07).
• Revenue trajectory (run-rate): ~$9B end-2025 → $14B (Feb 2026) → $19B (Mar) → $30B (Apr 2026). VentureBeat
• UNVERIFIED / forward-looking: reports of a future round at >$900B valuation and a possible IPO "later this year" — talks/rumor stage, not closed as of 2026-06-05. [VentureBeat / search aggregation]

Gulf money in Anthropic: MGX (Abu Dhabi, Mubadala+G42 vehicle, targeting $100B AUM) co-led; QIA participated. MGX separately co-led xAI's Jan 2026 round and is a Stargate partner ($7B). Bloomberg 2026-02-17, CNBC 2025-10-15

4. Meta — off-balance-sheet datacenter financing + bond issuance

Meta is financing its largest AI datacenters via off-balance-sheet SPV/JV structures so the debt does not consolidate onto Meta's balance sheet.

Hyperion (Richland Parish, Louisiana) — Blue Owl JV

• Oct 21, 2025: JV with funds managed by Blue Owl Capital for ~$27B in total development costs. Blue Owl owns 80%, Meta retains 20%. Blue Owl contributed ~$7B cash; Meta received a ~$3B one-time distribution (monetizing its stake). Debt issued to PIMCO and select bond investors via private offering; Morgan Stanley arranged. Meta provides construction/property management; a capped residual value guarantee over 16 years. Meta press 2025-10-21, CNBC 2025-10-21, DCD
• Magnitude / structure: reported as the largest private-credit transaction ever (~$30B incl. ~$2.5–3B equity). PIMCO ~$18B, BlackRock >$3B (per Bloomberg/secondary; not confirmed in Meta's press release — Meta only named PIMCO). Site: >4M sq ft, up to 5GW, completion ~2029. Prometheus (Ohio) is Meta's other named flagship cluster (~1GW, 2026).
• Off-balance-sheet point: Much of the project debt does not appear on Meta's public balance sheet — this is the key second-ring "hidden leverage" story.

Bond issuance

• Oct 30, 2025: $30B six-part bond — the largest US corporate bond offering of the year, ~$125B in orders (record demand). Maturities 5/7/10/20/30/40yr. Bloomberg 2025-10-30, The DESK

Capex

• FY2025 capex guided to ~$70–72B; FY2026 capex guidance ~$115–125B (range across reports; Wolf Street pegs the hyperscaler aggregate at ~$700B for 2026). Wolf Street 2026-02-07 — exact final FY26 figure carries spread across sources; treat as ~$115B+.

5. Custom silicon — Broadcom (AVGO), AMD, Marvell

Broadcom → OpenAI / Google / Meta / Anthropic

• OpenAI: 10GW custom XPU (Oct 13, 2025). OpenAI designs accelerators + systems; Broadcom co-develops/deploys; first deployment H2 2026; 3nm/2nm; total through 2029. (1.3GW targeted in 2027.) OpenAI 2025-10-13, Broadcom IR, CNBC 2025-10-13
• Google TPU: long-term supply agreement; Broadcom develops/supplies future TPU generations under a contract reported through 2031 (announced ~April 6, 2026). CNBC 2026-04-06
• Meta MTIA: expanded/extended through 2029 (~April 14, 2026); >1GW initial, multi-GW scale-up; ~3GW expected through end-2028. Tom's Hardware
• Anthropic: 1GW access in 2026, additional 5GW from 2027 (via Google TPUs co-developed by Broadcom). Futurum
• Backlog / revenue (Q2 FY2026 call, June 3, 2026): AI semi revenue $10.8B in the quarter (+143% YoY); AI bookings >$30B in the quarter; Q3 AI guide ~$16B; FY2026 AI forecast ~$56B; 2027 >$100B AI reiterated; consolidated backlog reported ~$110B (prior quarters). Broadcom confirmed 6 custom-XPU customers (Google, Meta, OpenAI, Anthropic + 2 unnamed). Motley Fool transcript 2026-06-03, TechTimes 2026-06-03
• NEW — Broadcom AI XPU compute-financing platform with Apollo, Blackstone et al. to deploy >20GW; first tranche ~$35B. (A second-ring financing vehicle of its own — mirrors Meta's SPV approach.) Motley Fool transcript 2026-06-03

AMD → OpenAI (noted, covered elsewhere)

• AMD–OpenAI: ~6GW Instinct (MI450) deal with a warrant for up to ~160M AMD shares (~10%) vesting on deployment/price milestones (Oct 2025). Flagged here for completeness; detailed in the core-ring file.

Marvell

• Custom-silicon/ASIC supplier (Amazon Trainium ASIC partner historically, Microsoft Maia work). No single named mega-XPU deal at Broadcom's scale in this ring; relevant as the #2 custom-ASIC house. (DEF 14A FY2025 on EDGAR.)

6. Sovereign / Gulf money threading the web

• MGX (UAE / Abu Dhabi): Mubadala+G42 vehicle, ~$100B AUM target, up to $10B/yr deployment. Co-led Anthropic Series G; co-led xAI (Jan 2026); Stargate partner ($7B); part of $40B Aligned Data Centers acquisition (with BlackRock GIP, Oct 2025); investor in OpenAI. Bloomberg 2026-02-17
• PIF (Saudi): in talks re: OpenAI's ~$40B round (with MGX). MenaBytes
• QIA (Qatar): Anthropic Series G participant.
• GIC / Temasek (Singapore): GIC co-led Anthropic Series G; Temasek participated.
• SoftBank Vision Fund: primary Stargate funder (~$19B committed, 40%); central to OpenAI's capital stack (core ring).

Key risk / circularity narrative

The second ring rhymes with the OpenAI/Microsoft/Nvidia core: hyperscaler-investors are also the vendors. Google and Amazon have each pledged tens of billions into Anthropic while simultaneously signing Anthropic to $100B+ multi-year cloud/chip commitments — so a large share of "invested" capital round-trips back as the investor's own revenue. Meanwhile, the actual datacenter buildout is increasingly financed off the hyperscalers' balance sheets (Meta–Blue Owl ~$27B SPV; Broadcom's new ~$35B+ XPU financing platform; MGX/BlackRock private-credit vehicles), pushing AI infrastructure leverage into private credit (PIMCO, Apollo, Blackstone, Blue Owl) rather than onto public equity balance sheets.

Unverifiable / soft items (flagged)

• Exact PIMCO ($18B) / BlackRock (>$3B) splits on Hyperion — secondary press only; Meta's release names only PIMCO.
• Meta FY2026 capex exact figure — sources span ~$115B–$125B.
• Anthropic >$900B next round / 2026 IPO — rumor/talks, not closed.
• Broadcom's two unnamed XPU customers (analyst guesses: Apple, ByteDance) — unconfirmed.
• Some Broadcom per-deal revenue estimates (e.g., ~$21B Anthropic, ~$46B Google) are analyst models, not company-disclosed.

Where this sits in the larger pattern (added 2026-06-11)

Amazon's and Google's mark-to-market gains on the AI labs they fund are the second self-marked locus (fair-value / equity marks), formalized in reflexive_marks (M1–M4) and the broader self_marked_value theorem alongside bank HTM (macro-bank-htm-marks), private credit (macro-private-credit-marks), insurance captives (spec-insurance-bermuda), and AI-compute depreciation (fin-ai-depreciation-debttrap). Two consequences tie this file to the newest work: (1) those gains must reverse if a public price clears below the last private mark (the MarkUnwind trace) — and the cross-sectional ~91% common factor means the reversal would not be idiosyncratic but shared across the marked classes; (2) the hyperscalers' own datacenter capex carries the depreciation/duration-mismatch problem (fin-ai-depreciation-debttrap) — Meta's Hyperion and Google's TPU build are debt-/lease-financed against compute that ages in ~2–3 years.
