Analyst Karan Singh Arora explained that the slight miss in data center sales dampened excitement. He noted that Wall Street wanted perfection and instead got results that were strong but not flawless.NVIDIA $NVDA just posted another record Quarter. Revenue beat Margins strong Guidance above Street Yet the stock sold off sharply! What went wrong? Let’s break it down pic.twitter.com/xHvxzmmKSp— Karan Singh Arora (@thisisksa) August 28, 2025Guidance for Q3 stood at $54 billion in revenue, plus or minus 2%, ahead of the $52.5 billion forecast. Still, this excluded any potential contribution from H20 AI chip sales to China. Restrictions barred shipments in Q2, leaving a $2 to $5 billion revenue gap if rules remain unchanged.Investors also grew cautious about the pace of hyperscaler spending. With valuations already stretched, traders were quick to react to any uncertainty. Even with revenue growth intact, the absence of clarity on China weighed heavily.Long-term drivers remain intact, including sovereign AI projects and broader data center demand. However, the near-term risks continue to revolve around China policy shifts and the spending patterns of large tech customers.The post Nvidia Beats Wall Street in Q2 but Stock Tanks on China Uncertainty appeared first on Blockonomi.
