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.

WISTA Cyprus Uses Music And Creativity To Bring The Sea Closer To The Next Generation

WISTA Cyprus brought members and their families together in Limassol for a children’s workshop focused on the Mediterranean monk seal, the sea, and the marine environment as part of its World Maritime Day 2026 activities.

A Creative Entry Point To Maritime Awareness

The workshop, titled Here Only Monachus, took place on September 19 at the Limassol Municipal Gallery and offered children an engaging introduction to the Mediterranean monk seal (Monachus monachus) through music, sound and creative activities.

Led by Rebecca Katsaris, associate educator at Enalia Physis, and music educator Christina Charalambidou, the session invited children to listen closely to the sounds of the sea, experiment with instruments and collaborate on creating their own musical piece.

Building Family Connections Around The Maritime World

For WISTA Cyprus president Anna Pittalis, the event was as much about community as it was about education.

“Our members came together not only as colleagues and professionals, but also as mums and dads, bringing their children with them,”

she said.

Pittalis added: “Our connection with the sea starts long before a career in maritime. It starts with curiosity, with discovering what is beneath the surface, and with learning to appreciate the world around us.”

Part Of A Broader Maritime Day Programme

The workshop formed part of WISTA Cyprus’ wider programme for World Maritime Day 2026, observed under the theme From Policy to Practice: Powering Maritime Excellence.

For the association, creating meaningful opportunities for younger generations to engage with the marine environment is also part of strengthening long-term ties to the maritime sector.
