CoreWeave stock is firing on all cylinders: get out before the engine overheats

CoreWeave Inc (NASDAQ: CRWV) remains in a sharp uptrend this morning as investors continue to cheer its 15-year lease agreements with Applied Digital Corp (NASDAQ: APLD).

Including today’s gains, the artificial intelligence infrastructure firm is up well over 250% versus its initial public offering (IPO) price of $40.

While the company’s top-line growth sure looks compelling and the massive investor enthusiasm may tempt investors in search of the next Nvidia to pile in, a closer look reveals CRWV is sprinting towards growth with the throttle wide open – and running on borrowed fuel.

CoreWeave’s fundamentals narrate a troubling story: soaring losses, extreme customer concentration, and a capital structure built on shaky financing.

With sky-high expectations already baked into the CoreWeave stock price, the AI infrastructure company may be far more vulnerable than it appears.   

CoreWeave is bleeding cash and borrowing to build

CoreWeave saw its net loss more than double to about $315 million in its latest reported quarter.

A key driver? Interest expenses, which ballooned by 549% year-over-year to $264 million.

This staggering figure reflects the company’s growing reliance on asset-backed financing to fund its aggressive data center, an inherently risky strategy for the current rate environment.

Management has guided for a massive $20–$23 billion in capital expenditures in 2025 alone, a sum that dwarfs the company’s annual revenue by roughly 5x.

Simply put, CoreWeave is spending far more than it’s making, and financing that gap with debt tied to physical infrastructure – a setup that can unravel quickly if cash flows stumble or interest rates push up.

Even more concerning is the fragility of those cash flows. CoreWeave’s business is dangerously concentrated: Microsoft accounted for a staggering 62% of its 2024 revenue.

While its new deal with OpenAI may help diversify its customer base, the broader risk remains – if just one of its hyperscaler clients pulls back or builds in-house capacity, CoreWeave’s financial model could crack under pressure, potentially leading to a significant decline in CRWV share price.

CRWV shares are pricier than Nvidia, with none of the profits

Following today’s rally, CoreWeave Inc. has transformed into a $71 billion behemoth. Yet, it’s still operating at a loss and is not expected to reach profitability until 2026.

Analysts project continued triple-digit growth, but even those bullish expectations don’t seem to justify the AI stock’s current valuation. To compare: Nvidia, which trades at about 39x forward earnings, is solidly profitable, dominant in AI hardware, and generates free cash flow.

CoreWeave, by contrast, trades at a significantly higher multiple (forward sales) – some estimates peg it above 25x 2024 revenue, with negative earnings and heavy reliance on external financing.

Such a valuation may make sense in a zero-rate world flush with easy money.

But in today’s environment, where capital is expensive and competition from deep-pocketed hyperscalers looms large, CoreWeave stock looks more like a speculative flyer than a foundational play on AI.

Is it worth buying CoreWeave stock?

CoreWeave’s stock is red-hot, but the fundamentals show cracks beneath the surface.

Soaring debt, rising interest expenses, and dangerous customer concentration make this a high-wire act with little margin for error.

For investors chasing AI infrastructure exposure, there are safer ways to play the theme.

Unless you’re comfortable with massive volatility and the very real risk of a reversal, now might be the time to take profits before the engine overheats.
