To The Moon

The AI infrastructure sell-off has exposed a question investors can no longer ignore: Can companies renting out computing power turn explosive demand into sustainable profits?

$CoreWeave, Inc.(CRWV)$  and $NEBIUS(NBIS)$  are at the centre of this debate. Both companies are benefiting from the enormous demand for AI computing capacity, but their business models and financial risks are different.

Their upcoming earnings reports could provide an important test of whether the recent sell-off has created a buying opportunity or revealed deeper problems in the AI infrastructure trade.

CoreWeave: Strong demand, but financing is the concern

CoreWeave has built a substantial business by providing cloud computing infrastructure for AI developers and major technology companies. Its second-quarter 2026 revenue reached $2.575 billion, more than double the same period a year earlier. Its revenue backlog also reached approximately $104 billion at the end of June.

Those figures demonstrate significant customer demand. However, growth comes at a high cost.

In Q2, CoreWeave reported a $626 million net loss and $640 million in net interest expense. The company is investing heavily in data centres, GPUs and supporting infrastructure, much of which requires external financing.

This creates a difficult balance. More investment can increase future revenue, but borrowing costs and capital commitments can also put pressure on cash flow.

For the upcoming results, I would focus on revenue growth, operating margins, interest expenses, free cash flow and whether the company can finance its expansion without continually increasing its debt burden. 

Nebius: A different funding structure

Nebius is also expanding rapidly in AI cloud infrastructure, but its funding structure deserves attention.

The company has attracted large customer commitments, and customer prepayments can help fund infrastructure expansion before all the associated costs are incurred. This may reduce reliance on borrowing compared with a more debt-dependent expansion strategy.

However, customer commitments are not the same as cash profits. Nebius still needs to build data-centre capacity, secure power, obtain GPUs and deliver services on schedule.

Its upcoming results should show whether rapid revenue growth is translating into improving margins and whether infrastructure expansion is keeping pace with customer demand.

Investors should also examine capital expenditure, customer prepayments, cash reserves and management’s outlook for the remainder of 2026.

The bigger issue: AI demand versus the cost of supplying it

I don’t think the recent sell-off automatically means the AI boom is over. Demand for computing power may continue growing, but investors are becoming more selective about which companies can actually benefit from it.

A large backlog looks impressive, but it does not guarantee attractive returns. Revenue growth is encouraging, but it does not automatically mean positive free cash flow. And access to financing matters enormously when a company needs billions of dollars to expand.

This is why I would not treat CRWV and NBIS as interchangeable investments.

CoreWeave needs to demonstrate that its scale and customer demand can justify its financing costs. Nebius needs to prove that its rapid expansion can be delivered efficiently and converted into sustainable earnings.

My view: The upcoming earnings are less about whether these companies can beat revenue estimates and more about whether they can demonstrate a credible path towards financial sustainability.

The AI infrastructure opportunity may still be substantial, but the market is moving beyond rewarding growth at any price. Companies that can manage capital expenditure, control financing risks and generate cash should be better positioned for the next stage of the AI cycle.

For now, I would rather see the financial results and management guidance before calling either stock a bargain. A sharp share-price decline can create an opportunity, but it can also be a warning.
