Evening Analysis — 2026-10-16

Dek

The money behind AI data centers is getting nervous, but the power grid is still filling up. The gap between those two is tonight's story.

The Big Shift

Today the doubt about AI spread from stock prices into lending. Bonds from CoreWeave and other data-center builders fell on worries that they are spending and borrowing too much ¹. Stock prices are mood. Bond prices are what it costs to borrow, and most of the AI buildout runs on borrowed money. If those costs keep rising, the first casualties will be the debt-funded builders (IREN, WULF, CoreWeave), not the cash-rich giants. Their equipment suppliers (VRT) would feel it a few quarters later.

Analysis

Compute and capital. Three signals point the same way. Chip stocks are on their longest losing streak since 2008, and the Nasdaq 100 just had its worst week since the April 2025 tariff shock ². Gartner calls AI data-center spending "unsustainable" and warns of $3.5 trillion in possible write-downs, meaning assets marked down because they earn less than they cost ³. And the credit market is now pricing the same risk. Execution is wobbling too: Nscale's Norwegian site is delayed after cooling leaks and a fire, just as the company prepares to go public ⁴. What it means: the "growth funds itself" pillar for IREN and WULF is the weakest link tonight. VRT and GEV are exposed mainly through their high valuations, not their order books.

Power. On the physical side, demand is not slowing. PJM, ERCOT and SPP, three of the big regional grid operators, all set summer peak-load records ⁵. AEP is buying up to 1.6 GW of Mainspring generators, which make power on-site from gas without large turbines. It also plans to spend about $4 billion on a 702-MW Bloom fuel-cell project under contract to Google ⁶. Digital Realty is scouting a gigawatt-scale site in Indiana ⁷. What it means: builders with real cash and signed customers (Google, the large utilities) are still committing. The split is between strong balance sheets and leveraged ones, not between AI and no AI. That supports GEV's order book even while its valuation takes a hit.

Permission. The real bottleneck keeps showing up in rules and politics. PJM is drafting "ride-through" rules, which require big computing loads to stay connected through voltage dips instead of dropping off and destabilizing the grid [source](//www.rtoinsider.com/148555-pjm-pc-teac-briefs-100626/). Bonneville Power is testing an "open season" process to connect large loads faster [source](//www.rtoinsider.com/148536-bpa-seeks-to-connect-large-loads-under-open-season/). The Ohio Supreme Court's ruling on AEP's data-center tariff, which makes data centers pay more of their own grid costs, could set a pattern for other states [source](//www.rtoinsider.com/148560-national-ramifications-seen-in-ohio-aep-tariff-suit/). Meanwhile the local backlash is becoming a midterm-election issue and is colliding with federal permitting reform ⁸. What it means: even if money stays available, getting a grid connection and local approval decides who gets built and when. Projects that already have both are worth more.

Materials. Copper sends mixed signals, and the mix matters. The ICSG, the copper industry's main forecaster, expects the refined surplus to more than triple next year, even after counting AI demand ⁹. The price has fallen three days in a row ¹⁰. But metal outside the US is getting scarcer ¹¹. Mercuria just delivered 12,000 tons of Congolese copper to the US government's Project Vault stockpile ¹². Tech companies are reportedly sounding out stakes in Anglo American ¹³. What it means: the "global structural deficit" pillar for SCCO is cracking. What's left is a story about location and politics: copper may be plentiful in total but tight where governments and buyers want it. That's a weaker reason to own a single miner.

Geopolitics. Copper is the clearest case. Stockpiling, the Army's supply-chain mapping deadline ¹⁴, and Beijing's veto over the Anglo–Teck merger all treat metal as a security asset. Taiwan is building out its drone forces with US partners (Shield AI, AeroVironment), which shows how much the chip supply chain depends on deterring China. What it means: policy can create local shortages even during a global surplus. That helps US-based or allied supply more than global producers.

What Would Prove Us Wrong

• Big tech keeps spending, and the bond scare fades (hits our bearish turn on VRT, IREN, WULF). If Microsoft, Alphabet, Amazon and Meta keep or raise their capex plans in their late-October earnings, and CoreWeave's bond prices recover within two weeks, today was a scare, not a turn. If any of them cuts guidance, or a data-center debt deal is pulled or reprices sharply, the downgrade deepens.
• Grid connections speed up (hits the "permission, not metal, is the bottleneck" thesis). If BPA's open season or PJM's large-load process starts approving multi-gigawatt connections in months instead of years, permission stops being the main constraint. Then money becomes the main thing limiting the buildout.
• Copper outside the US stays tight despite the forecast surplus (hits our SCCO downgrade). If exchange stocks outside the US keep falling and Chile or Peru supply disruptions return over the next month, the ICSG surplus is only on paper. Then SCCO's lower conviction is a mistake.

Thesis Impact

• SCCO | Conviction: DOWN | Surprise: MED | The International Copper Study Group (ICSG, the industry's main forecaster) now expects the global surplus of refined copper to more than triple next year. Mine and smelter output is growing faster than demand, even with AI and data centers counted. Copper has also fallen three days in a row. This CONTRADICTS pillar 1, the structural deficit. FCX at 0.49 already prices this in; SCCO at 0.75 doesn't yet. SCCO being the lowest-cost producer softens the hit but doesn't cancel it. Antofagasta's weak 2027 output guidance and tech firms circling Anglo American partly offset it, but they're one company's supply news, not a market-wide shift. | ⁹
• VRT | Conviction: DOWN | Surprise: MED | NEW: CoreWeave's bonds and other data-center bonds are falling on worries about capex and debt overhang (how much these builders spend and borrow). Bloomberg (T1) separately reports chip stocks on their longest losing streak since 2008, with the Nasdaq 100 having its worst week since April 2025 as investors question the AI trade. If debt markets get tighter, the companies building AI data centers can afford fewer new ones, and that is VRT's order source. This CONTRADICTS pillar 2 (orders follow hyperscaler capex) and pillar 3 (the premium valuation). No capex cut has happened yet, so the trigger isn't hit, but the risk is now showing up in credit markets and not just in commentary. | ¹
• IREN | Conviction: DOWN | Surprise: MED | CoreWeave is IREN's closest listed peer in GPU cloud. Its bonds falling on debt-overhang fears means lenders are pricing more risk into the whole sector. That makes it costlier for IREN to fund its GPU and data-center buildout without heavy dilution. This CONTRADICTS pillar 3 (growth funds itself) and weakens pillar 2 (the AI Cloud scales). The Nasdaq selloff (T1) adds to it. | ¹
• WULF | Conviction: DOWN | Surprise: MED | Same CoreWeave and data-center bond selloff. WULF pays for its Lake Mariner buildout with debt, and its hosting tenants also borrow from these same credit markets. So the pressure hits both its financing and its tenants. This CONTRADICTS pillar 3 (financing without crippling dilution) and adds risk to pillar 2 (contracts ramp on schedule). Nothing signed has slipped yet. | ¹
• GEV | Conviction: DOWN | Surprise: LOW | Bloomberg (T1, NEW): AI stocks are getting sold off broadly and investors are openly doubting the AI trade. This mainly hits pillar 4 (the premium multiple is justified). It CONTRADICTS that pillar on valuation only. The order backlog isn't affected, and nothing points to cancellations. Small move. | ²
