To The Moon

After weeks of nervous trading, AI-related stocks finally delivered a powerful rebound on Wednesday. $CoreWeave, Inc.(CRWV)$  surged nearly 25%, $NEBIUS(NBIS)$ climbed 15.4%, and semiconductor and optical technology stocks recorded strong gains. The $iShares Semiconductor ETF(SOXX)$ also rose 6%.

Even $NVIDIA(NVDA)$ recovered almost 3%.

What changed? Investors received some reassurance from CoreWeave’s earnings call, particularly around its funding requirements, profitability plans and the economics of running AI cloud infrastructure.

This matters because CoreWeave has become an important part of the AI investment ecosystem. It provides cloud access to advanced computing chips, allowing businesses to rent computing capacity rather than build their own infrastructure.

However, its rapid expansion has also raised concerns about borrowing, capital requirements and whether AI demand can justify the enormous investment across the industry.

1. CoreWeave addresses the debt concerns

One of the biggest concerns surrounding CoreWeave has been how it will finance its expansion.

Building AI data centres requires substantial upfront investment in chips, servers, power and facilities. Borrowing can accelerate growth, but it also creates financial pressure if customer demand slows or financing costs increase.

During its earnings call, CoreWeave outlined its path towards profitability and said it intends to avoid a particularly risky form of debt. It also expects to raise less than US$5 billion in additional parent-level capital through the end of 2027.

This appears to have reassured investors that the company is paying attention to its balance sheet rather than pursuing growth at any cost.

Another interesting detail is that demand is strong enough for CoreWeave to charge higher prices for access to some older-generation chips.

That suggests AI computing demand may be broader than investors previously assumed. Not every customer needs the newest and most expensive hardware to run AI workloads.

2. The recovery extends beyond CoreWeave

The rally spread across several important parts of the AI supply chain.

• Nebius: Rose 15.4%, reflecting renewed confidence in AI cloud infrastructure.

• Lumentum: Gained 10.7%, benefiting from demand for optical technology used in data-centre connectivity.

• Coherent: Advanced 9.3%, highlighting investor interest in optical components.

• Marvell: Climbed 9.3%, as networking and custom silicon remain important to AI infrastructure.

• SanDisk: Jumped 13.7%, while Micron gained nearly 12%, showing renewed interest in memory demand.

This broad participation is encouraging because AI infrastructure requires more than GPUs. It also depends on memory, networking, optical connections, power and data-centre capacity.

If spending continues, companies across these areas could benefit.

3. OpenAI’s growth provides another reason for optimism

Another factor supporting sentiment was a Wall Street Journal report on OpenAI’s financial performance.

The report indicated that revenue reached approximately US$10 billion, with growth of around 50% between the second and third quarters. However, it also highlighted a modest increase in adjusted losses and noted that rival Anthropic was operating more efficiently.

This creates an important distinction for investors.

Strong revenue growth supports the argument that demand for AI products is real. But revenue growth alone does not prove that the business model is profitable.

Investors need to understand whether AI companies can turn growing usage into recurring revenue, improve margins and generate sufficient returns to justify their enormous infrastructure spending.

4. Is the AI sell-off finally over?

I would be careful about calling this a confirmed recovery.

CoreWeave’s results have helped ease concerns, but the wider industry still faces several risks:

• High borrowing and infrastructure costs.

• Heavy capital expenditure by major technology companies.

• Questions about the profitability of AI services.

• Potential delays in data-centre construction and chip deliveries.

• The possibility that AI spending eventually grows more slowly than expected.

The key question is whether Wednesday’s rally attracts sustained buying or simply represents short-term relief after a period of heavy selling.

My investment view

I remain interested in the AI infrastructure theme, but I would focus on companies that can demonstrate real demand, manageable financing requirements and improving cash flow.

CoreWeave’s update is encouraging because it addresses one of the market’s biggest concerns: whether AI infrastructure companies can grow without taking on excessive financial risk.

I would now watch whether CoreWeave can deliver on its profitability plans, whether neocloud demand remains strong and whether memory, networking and optical companies continue reporting healthy orders.

The AI investment story is not just about how many chips companies can sell. It is increasingly about whether the entire ecosystem can turn massive investment into sustainable profits.

Wednesday’s rally restored some confidence, but consistent earnings and cash-flow growth will determine whether it lasts.
