Podcast: Decoder with Nilay Patel
Host: Nilay Patel, Editor-in-Chief, The Verge
Guest: Liz Lopato, Senior Reporter, The Verge
Date: November 13, 2025
Topic: CoreWeave, the AI infrastructure gold rush, and the financial engineering powering the current AI boom

Episode Overview

This episode dives into the story of CoreWeave, a company that rapidly pivoted from crypto mining to AI infrastructure and now sits at the center of the so-called "AI bubble." Host Nilay Patel and Verge senior reporter Liz Lopato explore CoreWeave's unusual origin, intricate financial relationships—particularly with Nvidia—and the implications for the broader AI industry if the bubble pops. They also dissect the complex mechanisms of risk, debt, and circular financing that are fueling the AI boom.

Key Discussion Points and Insights

1. Why CoreWeave Is Central to AI "Bubble" Discourse

• The Picks and Shovels Analogy:
  • Investors now look for infrastructure plays ("picks and shovels") instead of building direct AI products.
  • CoreWeave emerges as a leading 'neocloud'—a company leasing out vast banks of Nvidia GPUs (04:06).
• CoreWeave’s Path to Public Markets:
  • The company provides more transparency due to its recent IPO, making it a rich subject for financial analysis (04:06).
• Market Dynamics:
  • Competitors like Amazon, Google, and Microsoft offer full-stack cloud services; CoreWeave essentially rents out compute power (05:00–06:48).

2. How CoreWeave Fits into the Cloud Landscape

• Simplified, Yet Sophisticated:
  • Unlike hyperscalers (AWS, Azure, Google Cloud) who offer extensive software/services, CoreWeave just supplies compute and plumbing for AI companies (06:08-06:48).
  • Their "moat" is limited: Engineering prowess, energy procurement, and chip access—not sticky software ecosystems.

Quote:

"It's a little more sophisticated than that, but not a lot more sophisticated than that...it's really hard to get energy, and that is a major supply constraint on AI right now. Coreweave has a pretty good track record...but it's not a huge moat."
—Liz Lopato (06:08)

• Risk of Disintermediation:
  • Microsoft's and Nvidia's roles are both customer and investor—meaning future competition is likely (07:54).

3. CoreWeave's Origin Story: From Crypto to AI

• Crypto Roots:
  • CoreWeave was founded by ex-commodities traders during the Ethereum mining boom.
  • Pivoted to AI as crypto faded, using their existing GPU stockpiles for new data centers (08:51).

Quote:

"It's crypto. Yeah, of course, it's crypto...these guys pivoted basically after the crypto boom in 2022 away from crypto, because in 2021 CoreWeave made all its money by mining Ethereum."
—Liz Lopato (08:51)

• Perfect Timing:
  • The company was positioned for the 2022–2023 AI boom, following the success of models like ChatGPT (09:44-10:08).

4. The CoreWeave–Nvidia Symbiosis

• Dependency and Influence:
  • CoreWeave only uses Nvidia chips—over 250,000 to date (11:01).
  • Nvidia is both a major investor and a customer, even backstopping unsold capacity, guaranteeing CoreWeave’s revenue (11:01–12:28).
  • Raises questions about the stability and incentives of such a tightly-coupled supplier–customer relationship.

Quote:

"It's just not possible for CoreWeave to exist without Nvidia...Nvidia has backstopped CoreWeave in a number of ways, including saying they will buy any excess compute that isn't sold to customers."
—Liz Lopato (11:01)

5. Clever Financial Engineering in the AI Gold Rush

• Risk Transfer via Special Purpose Vehicles (SPVs):
  • Companies use SPVs to fence off debt and risk exposure (14:51–16:52).
  • Allows giants like Microsoft to rent compute without risking their own capital or pristine credit ratings.
• Middleman Profits & Debt Risks:
  • CoreWeave assumes infrastructure risk; its clients retain agility.
  • CoreWeave is highly leveraged, relying on debt secured by its Nvidia chips (18:34).
• Chip Depreciation Uncertainty:
  • With chips as fast-depreciating collateral, the business hinges on AI workloads materializing before hardware becomes obsolete (19:14–22:31).

Quote:

"You look at CoreWeave and I see how much debt they've taken on—it really makes me nervous."
—Liz Lopato (18:34)

• The Urgency of AI Payoff:
  • Timelines for AI-driven value are uncertain. Adoption in traditional industries is expected to be slow, risking misalignment with debt repayment schedules (22:31–24:44).
  • Analogy to legacy tech over-promises (e.g., pets.com vs. Chewy) highlights caution around speed of change.

6. Investor Skepticism and Earnings Volatility

• Recent Earnings Misses:
  • CoreWeave's stock dropped after lowered revenue forecasts and project delays, despite surging AI hype (25:57–26:30).
• Market Mood Swings:
  • Sentiment on AI is shifting: less euphoria, more questions about sustainability and profit.
• Circular Financing Concerns:
  • Complex financial arrangements between OpenAI, Microsoft, Nvidia, and CoreWeave (money looping through investments, contracts, and back again) are making some investors jittery (28:37–30:52).

Quote:

"There’s some amount of money that is just going the whole way around. ... maybe more cynically, you’re passing around the same $5 like when you and your friends go out to eat."
—Liz Lopato (29:39)

7. Bubble Signals and What to Watch Next

• Bubble Markers:
  • Demand is currently for training, not inference; sustainable demand is uncertain (31:57).
  • If lighter AI models replace heavy compute needs, infrastructure value plummets.
  • Giants like Amazon, Meta, and Google can weather overbuild by repurposing assets; CoreWeave cannot (32:30–33:38).
• Comparison to Enron:
  • Use of SPVs and debt-heavy strategies echo tactics from the Enron scandal, albeit legally. Visibility into what’s really happening is becoming more opaque (33:43).

Quote:

"Looking at CoreWeave and the other Neo clouds... I kind of wondered if one might think of them as... special purpose vehicles for Nvidia."
—Liz Lopato (34:47)

8. What’s Next?

• Open Questions and Red Flags:
  • How quickly do these chips deteriorate in practice, and do SPVs mask the true indebtedness in the sector? (35:48–36:45)
  • Is the flywheel of debt, investment, and risk transfer robust—or teetering on speculative assumptions?
