'We are pushing the frontier across our entire AI stack': Microsoft's latest results show new cloud and AI returns - but reliance on OpenAI causes concerns

• Microsoft quarterly revenue up 17% to $81.3 billion, Microsoft Cloud revenue is 63% of this
• Investors are worried about over reliance on AI model makers, OpenAI and CapEx
• Nvidia still plays a role in Microsoft's plans going forward

Microsoft has posted a 17% year-over-year increase in quarterly revenue ($81.3 billion), but despite this success, it seems investors are concerned about bigger things at play than just the company's finances.

Share prices actually dropped 6% in after-hours trading, with investors likely worried about Microsoft's heavy reliance on AI model makers and huge capital spending.

And despite Microsoft forfeiting its right of first refusal as OpenAI's compute provider, the company is still heavily tied to the ChatGPT maker in more ways than one, which adds to the pressure it faces in gaining investor confidence.
