The News
Core Scientific's third-quarter 10-Q, filed with the Securities and Exchange Commission on November 5, adds a new risk factor on datacenter moratoriums, Texas curtailment rules and organised opposition. A 10-Q is the quarterly report a public company must file with the SEC, so a new risk factor in it is a formal warning to investors, not a passing comment. The timing is pointed: voters backed datacenter limits in 40 of 41 ballot measures in the midterm elections, and the backlash against new builds is now a disclosed business risk for the companies that host them.
The same filing quantifies just how concentrated the business has become. CoreWeave was about 84% of total revenue for the nine months ended September 30. Third-quarter colocation revenue — the money from renting out datacenter space and power — was $215.4 million, up 58% from the previous quarter, and colocation is now 84% of nine-month revenue, up from 14% a year earlier. The filing says that colocation revenue is "currently derived entirely from a single customer, CoreWeave." It also discloses that CoreWeave transferred some license agreements to CW SPV, a special-purpose vehicle and indirect CoreWeave subsidiary, adding a layer of counterparty structure — CoreWeave remains a primary obligor, but the filing says the practical ability to enforce recourse would depend on CoreWeave's financial condition at the time of any default. The company is billing 485 megawatts of the 590 megawatts it has contracted with CoreWeave, and holds about 2.6 gigawatts of gross utility power, with about 1.7 gigawatts leasable, across 11 sites.
The filing also shows the gap between today's revenue and tomorrow's. AMD-backed leases covering 530 megawatts do not start generating revenue until early 2027, so for now the growth story and the risk story are the same customer. CoreWeave reports its own third-quarter results on Tuesday, November 10, and Core Scientific's filing is, in effect, the first word on how the week's political backlash lands on the companies that actually host the AI build-out.
Colocation revenue is currently derived entirely from a single customer, CoreWeave.
Why It Matters
Concentration is the oldest risk in business, and this filing states it plainly. When one customer is 84% of revenue, every problem that customer has becomes your problem — and CoreWeave has plenty of its own, from the Texas backlash to the $16.3 billion of operating lease liabilities on its own balance sheet. The new moratorium risk factor is the filing's way of saying the political environment is now a business risk, not just a headline, and it lands on a company with no second customer to fall back on.
That is why the verdict is Bearish. The numbers are strong — 58% sequential growth in colocation revenue is a real business — but they are strong in exactly the way that makes a single-customer company fragile. The diversification that would fix it, the AMD-backed leases, does not start paying until early 2027. Until then, Core Scientific is CoreWeave, and CoreWeave is the story. The filing also puts a number on the capacity problem: 485 megawatts billing of 590 megawatts contracted with CoreWeave, and about 2.6 gigawatts of gross utility power with about 1.7 gigawatts leasable across 11 sites. The capacity is there; the customers are not — yet. Until the AMD-backed leases start paying in early 2027, every megawatt of that capacity is a bet on a single tenant.
Analyst's Take
Our call is Bearish. A company that gets 84% of its revenue from one customer is a bet on that customer, and this filing says so in the SEC's own language while adding a brand-new risk factor about the political backlash against datacenters. The growth is real — colocation revenue up 58% in a quarter — but it is growth on a single pillar, and the filing now warns that the pillar's own environment is getting harder.
What to watch: CoreWeave's third-quarter results on Tuesday, November 10, which will show whether the customer at the centre of this concentration is healthy; whether the AMD-backed leases due in early 2027 start to diversify the revenue; and whether the moratorium risk the filing flags turns into actual lost projects.

By The Numbers
FAQ
What is a 10-Q, and why does this one matter?
A 10-Q is the quarterly report a public company files with the US Securities and Exchange Commission. It is a legal filing, not a press release, so what it says about risks carries weight. Core Scientific's filing, made on November 5, adds a brand-new risk factor about datacenter moratoriums — the first time the company has formally warned investors that local bans could hurt its business.
How dependent is Core Scientific on CoreWeave?
Almost entirely. CoreWeave was about 84% of total revenue for the nine months ended September 30, and colocation — renting out datacenter space and power — is now 84% of nine-month revenue, up from 14% a year earlier. The filing says that colocation revenue is "currently derived entirely from a single customer, CoreWeave."
What is colocation, in plain terms?
Colocation means renting out space, power and cooling in a datacenter to another company, which installs its own computers there. Core Scientific owns the buildings and the power connections; CoreWeave owns the AI chips inside them. Core Scientific's third-quarter colocation revenue was $215.4 million, up 58% from the previous quarter.
What are the moratoriums the filing warns about?
Local bans or pauses on new datacenter building, driven by residents worried about power prices and water use. Voters backed datacenter limits in 40 of 41 ballot measures in the midterm elections, and the filing also flags Texas curtailment rules — rules that can cut a datacenter's power at times of grid stress — and organised opposition to new builds.
Does Core Scientific have other customers coming?
Not yet, in revenue terms. AMD-backed leases covering 530 megawatts do not start generating revenue until early 2027. Until then, the company is a one-customer business in a market where that customer, CoreWeave, is itself under pressure.
