GPU rents rise 17–21% on 1 October while the neoclouds' own loan documents show borrowing 100bp dearer

The Thursday news is a broker call and should be labelled as one: JPMorgan's Samik Chatterjee upgraded CoreWeave to Overweight from Neutral and raised his target to $125 from $120, arguing the company should lean into shorter contracts carrying premium pricing. CoreWeave closed Thursday at $90.13, up 3.72%, and gave it back on Friday. Nebius closed Thursday at $243.48, up 7.44%.

The pricing half of the thesis is verifiable at source, which is the most useful thing here. Nebius's own pricing page carries two columns — current, and effective 1 October 2026 — showing on-demand per-GPU-hour rates going from $3.85 to $4.50 for H100, $4.50 to $5.40 for H200, $7.15 to $8.50 for B200 and $7.85 to $9.50 for B300. Those are increases of 16.9%, 20.0%, 18.9% and 21.0%. Roundups describing this as up to 21% are accurate; the table is better, because it says which chip and from what. It is a rate card, not a revenue disclosure — what Nebius intends to charge, not what it will collect.

The debt half is also verifiable at source, and it cuts the other way. CoreWeave's own release of 18 May describes a $3.1 billion facility priced at SOFR plus 4.50%, roughly five and a half years, rated Ba2 by Moody's and BB+ by Fitch. Its release of 10 August describes a $2.6 billion facility at SOFR plus 5.50%, about five years, the same ratings, secured by infrastructure and by customer contracts averaging approximately three years in length. A hundred basis points wider in twelve weeks at unchanged ratings is a price signal from lenders, and the company's own words supply the structural reason: three-year revenue against five-year debt.

That is the argument now live in the market, and a reader does not have to take either analyst's word for it. Alexander Haissl of Rothschild & Co Redburn, who has a Sell and a $54 target, puts it as credit markets beginning to price risks equities largely ignore, citing precisely that hundred-point step. The rate card and the two loan releases are public, dated, and from the issuers. A 2026 revenue forecast and a large negative free-cash-flow figure circulating in coverage of the upgrade are not carried here, because the account does not say whose estimates they are.
