All-In on CoreWeave's bond rout: Chamath says the real risk is refinancing a $35B funding gap, not demand
Key points
Key takeaways from the All-In Podcast episode of 17 October 2026 ("CoreWeave Crash, AI Trade Cracks, Anthropic IPO Red Flags, Bill Gates Doomer"), with Chamath Palihapitiya, David Sacks, Jason Calacanis and guest Ben Horowitz (a16z).
What happened? CoreWeave shares fell about 16% on 14 October after yields on its 2031 and 2032 bonds rose to around 15%, a move Chamath flagged on X and Elon Musk answered with "yikes". Other neoclouds, including Nebius and IREN, sold off with it. By 15 October, CNBC reported CoreWeave's five-year credit default swap spread had at one point passed 1,140 basis points.
1. Chamath: the real risk is the cost of refinancing. He thinks CoreWeave's "box" model is sound: each customer contract, its GPUs and its data-centre lease sit in a separate financing vehicle. But he estimates CoreWeave still needs to raise roughly another $35B of debt to fund the contracts it has signed. Its average borrowing cost is about 8.5%, and one GPU-backed loan facility recently priced near 15%. Because its customer contracts are fixed-price, higher rates eat straight into its margin. By his team's estimate, that leaves CoreWeave within about $5B of breakeven on its obligations. He read the swap pricing as implying roughly even odds of default over five years, while saying he does not personally think the company is at real risk. His suggested fix: buy out some fixed contracts and sell the capacity at today's much higher spot prices.
2. Sacks: this is volatility, not a broken thesis. He argued that demand for compute is still growing, that even older H100 and A100 GPUs rent at premium prices, and that supply is limited by power and permitting. He also said project-level loans depend on the tenant's credit and the GPUs, not on CoreWeave's unsecured bonds. The bond selloff raises the implied yield in the secondary market, but CoreWeave still pays the coupon set at issue (about 9.6%). The metric he would watch is payback period: CoreWeave says it earns back the cost of a five-year contract in about 2.5 years.
3. Horowitz: tailwinds are strong, but the model is fragile. He called neoclouds "Rube Goldberg financial machines" and said a16z has avoided the category because of his experience with Loudcloud, where bandwidth bought on long-term contracts fell from about $1,500 to $50 per megabit between 1999 and 2001. He added that today the opposite is happening: GPUs are scarce, their useful life is getting longer, and he quoted Amazon's Andy Jassy as saying capacity is sold out beyond 2028.
4. Anthropic and OpenAI IPOs. Calacanis went through reported (unconfirmed) figures from an Anthropic investor day: Q3 revenue of $16.8B, an 85% adjusted gross margin, positive free cash flow and a target valuation of about $2T. Horowitz and Chamath expect strong demand for both the Anthropic and OpenAI listings, because those two companies threaten so many holdings in investor portfolios. Sacks said the company is strong and that the numbers circulating should be treated with caution until there is a filing.
