Investors may also need to look beyond the headline figures. Cramer pointed to potential constraints around data-center construction, electricity availability and supplies of components such as memory that could affect the rollout of new AI infrastructure.

Another issue is how AI projects are being financed. Spending arrangements involving chip suppliers and their customers have drawn scrutiny as companies commit large amounts of capital to expand AI capacity.

Competition is also becoming a focus, with rival processors and custom chips offering alternatives to Nvidia's technology. The company's ability to sustain demand and defend its position could influence sentiment across the AI market.

Cramer's warning puts added focus on Nvidia's guidance, customer spending and AI infrastructure demand ahead of earnings.
