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.

Limassol Port Electrification Awaits Grid Connection And EU Funding

Plans to equip Limassol port with shore-side electricity are advancing at the technical level, but unresolved administrative procedures, a pending grid connection and the need to secure European funding continue to delay implementation.

The proposed shore-power system, also known as cold ironing, would allow vessels to connect to electricity while berthed, reducing reliance on onboard engines and cutting emissions and noise in the surrounding area.

Technical Studies Near Completion

Transport Minister Evi Tsolaki said work is progressing through the EU-backed DecarbonLim programme, which is preparing the technical assessment and feasibility study required before construction can begin. The ministry is seeking regular updates from the Cyprus Ports Authority on the studies’ completion timetable.

The initiative also involves Frederick University, Eurogate Container Terminal Limassol, DP World Limassol, the Electricity Authority of Cyprus, the Cyprus Transmission System Operator and Limassol Municipality.

Grid Connection Remains A Key Hurdle

Despite progress on the studies, construction cannot proceed until the project secures a connection to the national transmission network.

Tsolaki said the ministry has requested land from the Department of Lands and Surveys for an electricity substation. Once the site is allocated, the relevant applications can be submitted to the Cyprus Transmission System Operator to advance the grid-connection process.

Until these steps are completed, the project will remain in the preparatory phase, even if the technical studies are finalised.

European Funding Adds Urgency

The feasibility work under DecarbonLim will support an application for construction financing, Tsolaki said. A competitive European funding call is currently open, and the ministry intends to submit an application within the required timeframe.

The funding window has raised concerns in parliament. MP Fotini Tsiridou warned that further delays could undermine Cyprus’ chances of securing EU support, noting that similar port electrification projects elsewhere in the bloc have already received funding.

Speaking to Entrepreneurial Limassol, published by the Limassol Chamber of Commerce and Industry, Tsiridou said she had observed some progress but had yet to receive a formal response to her parliamentary question.

Environmental And Commercial Benefits

Tsiridou argued that shore-side electricity would deliver benefits beyond emissions reductions, including less noise and air pollution for residents near the port.

“Our port should not be disconnected from the rest of the city,” she said, describing shore-power infrastructure as both a necessity and a European obligation.

Across Europe, port electrification is increasingly linked to environmental performance and competitiveness. By allowing compatible vessels to switch off auxiliary engines while docked, shore-power systems can reduce local emissions and noise while supporting wider decarbonisation goals.

Construction Timetable Still Unclear

The Cyprus Ports Authority signed a contract with DBA S.p.A. in July 2025 for a comprehensive study of the system’s technical, economic and environmental requirements. The work was intended to establish the basis for installation and identify any necessary port infrastructure upgrades.

More than a year later, key steps concerning land allocation, grid connection and financing remain unresolved. No timetable has been announced for completing these procedures or submitting the final funding application.

Limassol’s shore-power project therefore remains between planning and implementation. Its next milestones are securing the substation site, progressing the transmission-network application and obtaining construction financing. Until these are in place, the port’s transition to shore-side electricity cannot move into the construction phase.
