NEW YORK, July 29, 2026, 04:32 EDT – Nvidia Corporation (NASDAQ:NVDA) saw its shares decline 0.48% to $196.07 in premarket trading on Wednesday, extending a two-session rout that wiped out an estimated $237.9 billion of the company's market capitalization. The sell-off reflects growing investor scrutiny over the sustainability of massive capital expenditures on artificial intelligence infrastructure.
The valuation adjustment is significant in absolute terms: Nvidia's two-day market value loss is roughly 4.7 times its most recent quarterly operating cash flow of $50.3 billion. The company's market capitalization stood at $4.77 trillion as of Tuesday's close, with a trailing price-to-earnings ratio of 30.17.
Nvidia ended Tuesday's regular session at $197.01, up 0.25%, following a 4.99% decline on Monday. Despite the modest rebound, shares remained 4.75% below Friday's close of $206.84. The premarket decline on Wednesday is not yet reflected in the two-day loss calculation.
The company's earnings structure highlights its vulnerability to any slowdown in AI-related demand. During the first quarter, Nvidia's Data Center segment generated $75.2 billion in revenue, representing 92.1% of total sales of $81.6 billion. The company's projection for second-quarter revenue stands at $91 billion, with a possible variance of 2%, though this outlook excludes any data center compute sales to China.
Investor anxiety is not limited to Nvidia. The PHLX Semiconductor Index (SOX) dropped 4.5% on Tuesday and remains approximately 25% below its record closing high reached on June 22. Shares of SK hynix Inc. (KRX:000660) fell 9.6% on Wednesday after the memory chipmaker's record quarterly profit came in below forecasts, despite strong demand signals.
“Being strong is no longer sufficient in the current AI market,” said Gary Tan, portfolio manager at Allspring Global Investments, in comments to Reuters. SK hynix President Song Hyun-jong noted that “major customers are still requesting more memory supply,” indicating robust underlying demand.
Nvidia CEO Jensen Huang has described the pace of AI-factory construction as “accelerating at extraordinary speed,” and the company's first-quarter revenue grew 85% year-over-year. However, investors are now seeking evidence from Nvidia's largest customers that AI capacity is translating into revenue. Meta Platforms, Inc. (NASDAQ:META) and Microsoft Corporation (NASDAQ:MSFT) are both scheduled to report earnings later Wednesday, while Amazon.com, Inc. (NASDAQ:AMZN) will announce its results on Thursday.
The key focus for investors will be cloud expansion, capital expenditure, and cash generation. Revenue-supported investment could underpin Nvidia's high valuation, while continued weakness in cash flow would heighten concerns over AI profitability. The upcoming indicator will be customer economics rather than chip benchmarks.
Risks to Nvidia's outlook include the exclusion of China data center compute revenue from its guidance, ongoing export restrictions that pose a direct threat to earnings, and potential delays in infrastructure projects if interest rates rise or customer cash flow deteriorates.
