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.

ECB Orders Eurozone Banks To Prepare For AI-Driven Cyber Threats

The European Central Bank has given eurozone banks until October 31 to submit plans outlining how they will defend against AI-enabled cyber threats, reflecting growing concern among regulators over the impact of artificial intelligence on financial stability.

Regulators Raise The Alarm On AI-Powered Cyber Risk

The ECB’s directive comes as increasingly sophisticated AI models are expanding cyber capabilities, raising concerns about the resilience of critical financial infrastructure.

Some frontier AI systems, including Anthropic’s Mythos, have become so capable that access to them has been restricted, a limitation that currently applies to eurozone banks.

“These developments have potentially profound implications for the confidentiality, integrity and resilience of banks’ information and communication technology (ICT) systems,” the ECB said in a letter to bank chief executives.

Focus Shifts To Critical Systems

The central bank instructed lenders to prioritise internet-facing systems and other critical technology assets, including third-party software and open-source components. It also called for faster vulnerability management, stronger monitoring capabilities and improved cyber hygiene.

Beyond technical safeguards, the ECB urged banks to modernise ageing infrastructure and strengthen crisis management, recovery planning and information-sharing arrangements.

To support the initiative, the ECB has postponed a separate IT survey and said it may adjust inspections and other supervisory activities.

Cybersecurity Becomes A Financial Stability Issue

In a separate warning issued alongside the ECB’s letter, the European Systemic Risk Board (ESRB) said large-scale cyberattacks could undermine confidence in financial institutions and, in severe cases, trigger runs on banks or jurisdictions perceived as less secure.

“The ESRB considers these developments to be a source of systemic risks to the financial system,” the board said.

The report outlines a range of scenarios, from gradual losses of confidence in individual institutions to coordinated attacks targeting payment, clearing and settlement systems, potentially amplified by disinformation campaigns.

According to the ESRB, cyber incidents could spread rapidly through shared software providers and common technology platforms, allowing a single breach to escalate into a broader financial disruption.

A Growing Priority For Banks

The ECB’s latest guidance underscores how cybersecurity is becoming a core prudential issue rather than simply an operational concern.

As banks deepen their reliance on digital infrastructure, cloud services and third-party technology, regulators increasingly view cyber resilience alongside capital, liquidity and risk management as a key pillar of financial stability.
