1 serious warning sign in CoreWeave’s filings.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 2 Mar 2026, plus the 10-Q filed 12 Aug 2026 and 15 later 8-Ks.

• Weak checks on its own accounts

  Serious

  The company said its checks on its own accounts did not work at the end of its latest quarter. Mistakes could slip into the numbers.

  “Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2026 due to the material weaknesses in our internal control over financial reporting described below.”

• One big customer

  Worth knowing

  One customer brings in a big share of sales: 67% last year. Losing that customer would hurt.

  “We recognized an aggregate of approximately 67% of our revenue from our top customer, Microsoft, for the year ended December 31, 2025.”

• It carries a lot of debt: 6.5× its equity.

Whether the price already reflects the risks is what the deep dive is for.
