Power policy and open weights became the week's leverage while the closed frontier stalled.

Key takeaways

• FERC issued six simultaneous Section 206 show-cause orders telling PJM, MISO, SPP, CAISO, ISO-NE, and NYISO their tariffs 'appear unjust and unreasonable' for large data-center loads — national interconnection rules are being rewritten on a 60-day clock.
• Z.ai's GLM-5.2 shipped under a genuine MIT license, and independent testing says it beats GPT-5.5 on several long-horizon coding benchmarks at roughly one-sixth the cost — while Claude Fable 5 stayed government-suspended the entire week and Gemini 3.5 Pro slipped to July.
• Developers kept routing around the interconnection queue entirely (Cummins-Circe's 2GW behind-the-meter gas) while Amazon ($10B Missouri) and Google ($1.5B Alabama) added grid-connected capacity explicitly paying 100% of interconnection cost.
• Capital flow: CoreWeave's backlog ticked to ~$100B with a Cantor estimate of ~$131B by end-Q2; Meta-Crusoe's reported ~1.6GW deal stayed unconfirmed with both parties declining comment.
• Signal-vs-noise: GPT-5.6 and 'Grok V9' imminence is rumor with no primary artifact; treat the Meta-Crusoe deal as reported, not closed.
• Watch PJM's 2028/29 capacity auction results (~Jul 7) and the RTO/ISO compliance filings due by Aug 17 — the quarter's most important power-cost signals.

Flywheel arc · all-three

W25 moved at the two ends of the stack that the AI factory actually depends on — the grid and the open model layer — while the closed frontier marked time.

• The single most consequential event was regulatory: FERC's six simultaneous Section 206 show-cause orders told PJM, MISO, SPP, CAISO, ISO-NE, and NYISO their tariffs 'appear unjust and unreasonable' for large data-center loads, forcing co-location/behind-the-meter rules and cost-shift transparency within 60 days.
• Developers kept routing around the interconnection queue entirely (Cummins-Circe's 2GW behind-the-meter gas) while hyperscalers added grid-connected capacity explicitly paying 100% of interconnection cost (Amazon's $10B Missouri campus, Google's $1.5B Alabama expansion).
• The model layer's story was openness and stasis: MIT-licensed GLM-5.2 reportedly beats GPT-5.5 on several long-horizon coding benchmarks at roughly one-sixth the cost, while Claude Fable 5 stayed government-suspended all week and Gemini 3.5 Pro slipped to July.
• Net/net: pilot MIT-licensed GLM-5.2 for sovereign and self-host coding, keep multi-model fallbacks given the closed frontier's demonstrated fragility, and lock generation and long-lead transformers before GPUs.

What this means

The closed frontier paused — no GA from OpenAI, Google, or a restored Anthropic — and the momentum shifted to open weights and to how 'best' is measured. Architects should pilot MIT-licensed GLM-5.2 for self-host/sovereign coding now and re-baseline on the agentic AA v4.1 index; see The Model Pulse for the full architecture read.

Hardware was a follow-through week: the marquee catalysts (Micron earnings, SK hynix HBM4 dynamics, NVIDIA ISC, Groq's raise) all landed Jun 22-24, just outside the window. In-window the signal was OEM/system enablement (Supermicro order availability, HPE Vera CPU) and the custom-silicon thesis hardening. Operators should treat Vera Rubin as orderable but not shippable until H2; investors should keep diversifying toward the Broadcom/Marvell ASIC duopoly.

What this means

Networking was quiet between the March (OFC) and June-1 (earnings) news clusters: the week's signal was supply-chain capacity (Coherent's InP expansion addressing the laser chokepoint) plus a liquid-cooled 1.6T system, not a new chip design win. Critically, no second non-Broadcom vendor (Marvell or Credo) cited a fresh 1.6T/CPO production win — architects pressing for a second silicon source still have to wait.

Frontier Labs detail

Frontier-lab capital was quiet in-window. No new mega-round priced, and both OpenAI (Jun 8) and Anthropic (Jun 1) remain at the confidential-draft-S-1 stage with nothing publicly visible on EDGAR. The competitive pressure this week came from the open-weight side — GLM-5.2's MIT release at ~1/6 the cost of comparable frontier models — rather than from new financing. Treat this row as capital already committed; the next regime change is a public S-1.

Hyperscaler build-out continued with two incremental campus commitments — Amazon's $10B Montgomery County, MO site and Google's $1.5B Jackson County, AL expansion — both framed around paying full interconnection cost so ratepayers are not burdened. That framing is now standard messaging under FERC's cost-shift scrutiny.

On-Prem / Hybrid detail

The on-prem/sovereign row is increasingly a power-and-permitting story. FERC's Jun 18 orders force every major RTO/ISO to rewrite large-load interconnection within 60 days, while developers keep building their own generation — Cummins will supply 2GW of behind-the-meter gas to Circe's West Texas campuses, bypassing the ERCOT queue. In Europe, TensorX and Solstice lined up an up-to-$1B GPU/data-center financing facility (capacity, not a drawn commitment). Sovereign and on-prem buyers should assemble firm power and permitting before announcing GPU counts.

Signal score 5/5

FERC issued six simultaneous Section 206 show-cause orders rewriting large-load/data-center interconnection across all US RTOs/ISOs.

SIGNAL. The rules for how AI campuses connect and who pays are being rewritten nationally on a 60-day clock. This is a board-level siting and cost variable — pro-speed medium-term, but it injects near-term regulatory uncertainty into every US data-center plan.

Sources

FERC press release and orders; Day Pitney and Akin/JDSupra legal analyses. Primary regulatory action, multi-source.

Signal score 4/5

Z.ai's GLM-5.2 shipped MIT open weights that beat GPT-5.5 on several long-horizon coding benchmarks at ~1/6 the cost and lead the open-weight field.

SIGNAL. A genuinely permissive (MIT, no regional limits) frontier-adjacent open model is now self-hostable at a fraction of closed-API cost. Architects should pilot it for sovereign/self-host coding; it pressures closed-flagship pricing.

Sources

Z.ai release and Hugging Face card (primary); VentureBeat independent testing; Artificial Analysis placement. Caveat: SWE-Bench/Aider numbers not yet fully settled.

Signal score 4/5

Anthropic's Claude Fable 5 and Mythos 5 remained globally suspended for the entire week following the Jun 12 government order.

SIGNAL. The sovereign/regulatory single-point-of-failure on a top-tier closed model is not a one-day outage — it persisted a full week. Keep Opus 4.8/Sonnet fallbacks wired and do not single-source the frontier for production-critical paths.

Sources

Anthropic news page (primary) plus secondary trackers; no restoration date announced.

Signal score 2/5

GPT-5.6 (OpenAI) and Grok V9 (xAI) are launching imminently and will reset the frontier.

NOISE. Rumor with no primary artifact. Keep current baselines and do not delay procurement on an unreleased SKU; any GPT-5.6 was tracking to land after this window.

Sources

Backend codenames, transient routing strings, and prediction-market odds only; no system card or API contract. GPT-5.5 remains the documented flagship; 'Grok V9' does not exist.

Signal score 2/5

Meta has signed a ~1.6GW compute deal with Crusoe.

NOISE / unconfirmed. Treat as reported, not closed. The structural pattern (Meta adding external behind-the-meter compute) is real, but the specific deal is not yet verifiable for a procurement or investment decision.

Sources

Bloomberg-sourced reporting (Jun 18); both Meta and Crusoe declined to comment, terms undisclosed.

Frontier lab cash position (avg months runway, top 3)

Top 3 frontier labs (OpenAI, Anthropic, Google DeepMind) by disclosed runway, with xAI now public inside SpaceX. No new financing event in-window; both OpenAI and Anthropic remain at the confidential-draft-S-1 stage. Capital access stays wide; boards should not assume funding pressure forces near-term commercial concessions.

Hyperscaler capex / AI revenue ratio (top 4 weighted)

Top 4 hyperscalers (MSFT, GOOG, META, AMZN) weighted aggregate of capex divided by AI-attributable revenue. No new top-4 earnings print in-window; the incremental Amazon and Google campus commitments fit prior ~$725-805B 2026 capex guides. Investors should keep the bubble hypothesis on funding/conversion and now on FERC-driven siting cost, not demand.

CoreWeave revenue backlog

Booked but unrecognized revenue. Reporting puts backlog at ~$100B as of mid-June (vs the $99.4B Q1 figure), with Cantor Fitzgerald modeling ~$131B by end-Q2 — analyst-estimated, not company-guided. The official next print is Q2 in early August. Operators should keep watching conversion velocity over the headline figure.

NVIDIA Q-over-Q data center revenue

No within-window NVIDIA event; the next earnings print is Aug 26. The Q2 guide is $91B. In-window context (Supermicro Vera Rubin order availability, all three HBM makers volume-shipping HBM4 12-Hi) supports the ramp; packaging and power remain the binding constraints, not demand.

Open vs closed gap on coding (SWE-Bench / agentic)

The gap narrowed sharply in-window: GLM-5.2's MIT weights reportedly beat GPT-5.5 on several long-horizon coding benchmarks at ~1/6 the cost, and Artificial Analysis rebased its Intelligence Index to v4.1 (agentic), where open leaders sit ~44 and GLM-5.2 took the open lead. With Fable 5 suspended, the available closed leader is Opus 4.8 (AA v4.1 56). Architects should treat open self-host as a live procurement option, not a hedge.

Sovereign AI commitments (count / aggregate $)

Analyst-curated count of sovereign/national AI-compute commitments. No major new drawn commitment in-window; the only new item is TensorX/Solstice's up-to-$1B EU GPU/data-center financing facility (capacity, not a drawn commitment). Operators with EU workloads should track the facility but price in multi-year build timelines.

PJM 2026/27 capacity auction price ($/MW-day)

The 2026/27 BRA cleared at the FERC cap ($329.17); the 2027/28 BRA cleared at $333.44. The 2028/29 auction is still pending, with results expected around July 7, 2026, under a collar floor of $175 and a cap near $325. Architects should not assume near-term price relief; budget capacity at-cap through 2028.

Time-to-power, busiest US markets (months)

Months from new-load interconnection request to energization. FERC's Jun 18 show-cause orders aim to speed large-load studies and clarify cost allocation within 60 days — potentially pro-speed medium-term, but no near-term change. Large-power-transformer lead times remain ~128 weeks. Architects should pre-commit power and long-lead grid equipment before GPU SKUs.

Cost-per-task, frontier reasoning model

GLM-5.2 API ~$1.40/$4.40 per MTok; Grok 4.3 on Bedrock $1.25/$2.50

Median cost across frontier-tier reasoning models for a benchmark complex task. Open weights drove the ceiling down: GLM-5.2 lists at ~$1.40/$4.40 per MTok (~1/6 of comparable frontier) and Grok 4.3 went GA on Bedrock at $1.25/$2.50. Operators running agents at scale should re-benchmark on cost-per-task and pilot open self-host for routine work.

Custom silicon share of incremental AI compute

A J.P. Morgan note put the 2026 custom-ASIC market at ~$60-70B with Broadcom at 80-85% and Marvell 10-12%, reinforcing the thesis that ASIC units overtake merchant-GPU units by 2027. Investors with concentrated NVIDIA exposure should keep diversifying into the Broadcom/Marvell co-design duopoly and advanced packaging / power.
