Alphabet or CoreWeave in a crash: the Motley Fool picks Alphabet as CoreWeave's earnings land

The Motley Fool's Lawrence Nga says he'd pick Alphabet over CoreWeave if he could own only one AI stock in a market crash. His reasoning is that Alphabet has established businesses behind its AI spending. CoreWeave reported third-quarter results the evening before, and they change the picture in a few places.

That's the news. The more useful question is who actually pays for CoreWeave's growth, and who gets paid.

The Fool's case for Alphabet

Nga's argument is simple. Search, YouTube and Cloud give Alphabet several ways to earn from AI, while CoreWeave rents out computing power and needs huge amounts of capital to do it. He calls CoreWeave "a more speculative opportunity" for investors who can stomach the financing and execution risk.

The Alphabet numbers hold up. In its third-quarter filing, Alphabet reported revenue up 25% to $127.6 billion, Google Cloud revenue up 103% to $30.7 billion, and net income of $26.2 billion.

The CoreWeave section is older, though. It uses second-quarter figures (revenue of $2.6 billion, a $104 billion backlog) even though Q3 results were out by then. It also puts $9.4 billion of capital spending in Q2, while the Q3 cash-flow statement in CoreWeave's own release shows $9.4 billion of equipment purchases in Q3. I can't tell from these sources which quarter that figure belongs to.

What CoreWeave reported

According to the company's release, Q3 revenue was $3.66 billion, up from $1.37 billion a year earlier, and backlog reached about $132.5 billion. Net loss was $709 million. Full-year revenue guidance rose to $13.0 billion to $13.3 billion, and capital spending is now expected at $37 billion to $39 billion.

The market's first reaction was positive, though sources disagree on the size. After-hours trading showed a 5.7% rise to $51.51. By Wednesday premarket, reports put the gain anywhere from 13.7% to as much as 17%. Those are premarket numbers, not a close.

Who pays for the build-out

Lenders get paid first. Net interest expense hit $846 million in the quarter, against $310 million a year ago, and the company expects $1.05 billion to $1.15 billion in Q4. Debt stood at about $46.9 billion, or $66.2 billion once leases are counted.

Shareholders pay too. The same release shows a new at-the-market program for up to 35 million Class A shares and a $4.2 billion convertible note raise. The weighted share count rose to 559 million from 498 million a year earlier.

The third payer is customers. CEO Michael Intrator pointed to roughly $9 billion in customer prepayments and deposits expected over the next three months. Going by Investing.com's summary, CoreWeave also said it doesn't plan more parent-level unsecured debt through 2027. I think that's the most important line in the whole report, because it's the direct answer to the financing fears.

Who gains

Customers with guaranteed capacity gain first. KuCoin's write-up says management told investors that demand for 2027 capacity outstrips supply 10 to 1. Wayve, the UK self-driving company, is one of the newer names. CoreWeave announced a multi-year deal to supply its training compute, and I couldn't find a published price or length.

The deal matters because of concentration. Stocktwits notes that Microsoft made up about 67% of CoreWeave's 2025 revenue, so every new customer outside that circle helps the story.

Short-term holders gain as well. 24/7 Wall St. reports that Goldman Sachs upgraded the stock to Buy with a $106 target, down from $139.

The case against calling it settled

Not everyone's convinced. Short seller Jim Chanos argued on X that, even after stock compensation and a 10-year asset life, CoreWeave is a 2% to 3% pre-tax return business. He also said annualized revenue per active megawatt fell year over year. Management expects adjusted net income to turn positive in the first half of 2028, per TipRanks.

Alphabet isn't a risk-free comparison either. It sold $30 billion of equity and mandatory convertible preferred shares in June, and its total debt tops $100 billion, per its own offering document. Its shares also fell about 13% in one day on Oct. 29, wiping out roughly $490 billion, according to BigGo. NBC News put the loss at more than $500 billion.

What to watch next

The next test is whether those $9 billion in prepayments arrive on schedule, and whether Q4 interest costs land inside the guided range. Both come from CoreWeave's own forecasts, so they're checkable. Credit markets are the other signal: BigGo's figures put CoreWeave's default-risk spread near 1,088 basis points, against under 100 for Alphabet.

Honestly, I think the Fool's conclusion is reasonable on balance-sheet strength but dated on CoreWeave's numbers. The two stocks answer different questions, and a cheap share price alone doesn't settle either one. This is reporting, not investment advice.
