Why CoreWeave Stock Is Down 11.8%

CoreWeave stock plunged 11.8% on Tuesday as President Trump confirmed no Iran negotiations are underway, intensifying geopolitical fears. Rising oil prices and 20-year-high bond yields are creating a hostile environment for high-growth, heavily leveraged stocks. CoreWeave's debt-to-equity ratio exceeding 14 makes it particularly vulnerable in the current risk-off market environment.

Fed Chair Kevin Warsh's Job Just Got Much Easier. Here's What's Likely Next for the Stock Market As a Result.

Recent weak jobs data and moderating inflation have significantly reduced expectations for a Fed rate hike in September, easing pressure on Fed Chair Kevin Warsh.

Is CoreWeave Stock a Buy After a Co-Founder's Latest Insider Filing? Here's What to Know

CoreWeave CDO Brannin McBee sold 197,000 shares for $17.7 million on August 10, fully liquidating indirect holdings while retaining 11.1 million derivative securities. The sale reflects structured liquidity planning rather than loss of confidence. CoreWeave faces a critical execution test: with 112% revenue growth, $100B+ backlog, and recent operating profit, the company must convert backlog to cash faster than debt costs accumulate. However, $626M quarterly losses and $35B debt load amid customer concentration risks present significant downside if execution falters.

Despite the insider sale, McBee retains 6 million derivative securities and substantial holdings across family trusts, indicating minimal concern about his confidence in the company. CoreWeave continues to demonstrate strong revenue growth (112% quarterly increase to $2.6 billion) and a $100+ billion backlog, but remains unprofitable with $626 million in losses last quarter due to debt servicing and depreciation costs.

I Think You Missed CoreWeave's Zero-Cost-Basis Engine

CoreWeave's business model challenges the bear case that older GPUs become obsolete quickly. The company secured a multi-year renewal on 2020-era Nvidia A100 chips extending through 2029, demonstrating that older hardware can generate profitable revenue in subsequent contracts after initial debt is paid down. Debt markets are increasingly pricing in this residual value, with CoreWeave's new $2.6 billion facility having a longer maturity than underlying customer contracts, signaling lender confidence in GPU longevity.

CoreWeave Has $104 Billion of Contracted Revenue and a $59 Billion Market Value

CoreWeave reported a $104 billion revenue backlog as of June 30, 2026, up from $30.1 billion a year earlier, with Q2 revenue doubling 112% year-over-year to $2.6 billion. However, the company faces significant challenges: massive capital spending requirements ($35-39 billion in 2026), net losses widening to $626 million, and interest expenses ($2.6 billion annualized) exceeding projected operating income. While demand is strong, the stock's valuation at 56 cents per dollar of contracted revenue reflects the substantial costs and risks of converting backlog into actual delivered services.
