Nvidia Faces Historic Market Loss As DeepSeek Dents Confidence In AI’s Future

Nvidia experienced the largest single-day market cap drop in history on Monday, as its stock tumbled by 17%, shedding nearly $600 billion in value. This staggering loss is directly linked to a new development in the AI space—DeepSeek, a Chinese AI firm that unveiled its version of ChatGPT, raising concerns over the cost-efficiency and competitive positioning of U.S. AI companies.

Key Details

Nvidia’s shares experienced a severe decline, marking its worst daily percentage drop since March 2020, during the initial shock of the COVID-19 pandemic. On Monday, Nvidia lost a record-breaking $589 billion in market capitalization, more than doubling the previous one-day loss of $279 billion in September 2024. To put it into perspective, this is significantly more than Meta’s $251 billion market cap loss in February 2022.

As a result, Nvidia’s market valuation dropped from $3.5 trillion to $2.9 trillion, slipping behind Apple and Microsoft as the world’s most valuable company. Nvidia’s dramatic fall led a broader retreat in U.S. stocks, with the S&P 500 losing 1.5% and the Nasdaq dropping 3.1%. Other major players in the AI industry, such as chipmakers Arm and Broadcom, alongside Oracle, saw their stocks plummet by at least 10%.

The DeepSeek Effect

The cause of Nvidia’s catastrophic loss lies in DeepSeek’s release of its large-language model, which has cast doubt on the continued dominance of U.S. companies in generative AI. Initially, this might not seem like a negative development for Nvidia, as DeepSeek’s model was also powered by Nvidia’s powerful graphics processing units (GPUs), just like many other AI technologies. However, DeepSeek revealed that it spent just $5.6 million on Nvidia’s technology to develop its model. While experts believe this figure is likely a significant underestimation, it still calls into question the very foundation of Nvidia’s meteoric stock rise.

In recent years, Nvidia’s profits have skyrocketed, with projections indicating net profits could soar from $4.8 billion in 2022 to $66.7 billion in 2024, largely due to the soaring demand for its high-priced GPUs, which can cost up to $25,000 each. U.S. tech giants such as Meta, Tesla, and OpenAI have been among Nvidia’s biggest customers. However, if companies like these can replicate DeepSeek’s cost-efficient approach by using cheaper GPUs, Nvidia could face significant challenges in maintaining its market dominance.

As Ed Yardeni of Yardeni Research pointed out, this shift could be an unwelcome development for Nvidia.

Surprising Statistic

Nvidia’s near-$600 billion market cap loss on Monday exceeds the market values of all but 13 American companies, surpassing industry giants like UnitedHealth, Exxon Mobil, and Costco.

CEO’s Losses

Nvidia CEO Jensen Huang saw his wealth take a massive hit, losing $21 billion in a single day. His net worth dropped from $124.4 billion to $103.1 billion, according to Forbes estimates. Huang remains the largest individual shareholder in Nvidia, owning a 3% stake in the company.

Nvidia’s colossal market cap loss highlights the growing uncertainties in the AI sector, as DeepSeek’s cost-effective alternative to American AI models threatens to disrupt the industry’s balance. With AI becoming an increasingly competitive and global field, Nvidia’s future may hinge on how it adapts to these emerging challenges.

Rolls-Royce Raises Guidance As Defense And Power Systems Drive Growth

Rolls-Royce raised its full-year profit and cash flow guidance after reporting stronger-than-expected first-half results, supported by growth across its civil aerospace, defense and power systems businesses.

Underlying operating profit rose 46% year on year to £2.5 billion ($3.3 billion) in the first six months of 2026, while revenue increased more than 24% to £11.3 billion.

The company now expects full-year underlying operating profit of £4.7 billion to £4.9 billion, up from previous guidance of £4 billion to £4.2 billion. It also raised its free cash flow forecast to £3.8 billion to £4 billion, compared with £3.6 billion to £3.8 billion previously.

Shares rose as much as 6% in early trading before paring gains to trade about 4% higher.

Data Center Demand Supports Power Systems

Chief Financial Officer Helen McCabe told CNBC that orders in Rolls-Royce’s data center power business increased by more than 50% in the first half as operators invested in backup and on-site power systems.

The company has benefited from growing demand for power infrastructure as data center operators expand capacity.

Defense Spending Provides Additional Support

McCabe also said Rolls-Royce expects to benefit from higher defense spending in the U.K. and across NATO countries. She cited the U.K.’s long-term defense investment plan, which provides funding visibility through 2030 and beyond.

“We’ve had very positive initial conversations with the new government,” McCabe said, adding that the company supports its focus on growth, defense and industrial manufacturing.

Turnaround Continues

Chief Executive Tufan Erginbilgic said the company’s transformation strategy continued to deliver results. “Our transformation continues to deliver,” he said in a statement. “We have unlocked new growth opportunities across the Group.”
