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.

Cyprus Moves To Unlock More Solar Power With First Large-Scale Battery Storage Contracts

Cyprus is preparing to sign the first contracts for large-scale electricity storage batteries on Tuesday, a project expected to improve the grid’s ability to manage growing renewable energy production and reduce the curtailment of solar power.

A Long-Awaited Grid Fix

Energy Minister Michalis Damianos said the agreements will cover 120MW of centralised storage capacity that will be managed by the transmission system operator. The project, valued at €50 million, is expected to deliver the batteries in January 2027, with installation scheduled to take place over the following two to three months.

According to Damianos, the system should become operational by the summer of 2027, a period when both electricity demand and solar generation typically peak. He said the storage facilities will allow energy currently lost due to a lack of storage capacity to be retained and used when needed.

Why Storage Has Become Essential

The batteries are designed to absorb excess renewable electricity during periods of overproduction and release it back into the system when demand increases. Their introduction is expected to reduce the curtailments currently affecting solar generators and improve the use of renewable energy already being produced across the island.

Former Energy Minister George Papanastasiou told Sigma that planning for the project began in 2023 in cooperation with the European Commission. The objective was to address growing losses from renewable energy generation that the electricity network cannot currently absorb.

By the end of May 2026, approximately 160,000 megawatt hours of renewable energy had been lost through curtailments affecting residential photovoltaic systems, commercial solar parks, and wind installations. According to Papanastasiou, renewable electricity production exceeds demand during several hours of the day, leaving part of the output unable to be utilised.

The Cost Of Growing Faster Than The Grid

The challenge has become more pronounced as renewable generation capacity has expanded faster than the infrastructure required to manage surplus electricity. Data from the distribution system operator show that around 306 gigawatt hours of renewable energy were curtailed in 2025, compared with approximately 167 gigawatt hours a year earlier.

Papanastasiou acknowledged criticism that storage deployment has not kept pace with the growth of renewable energy projects, although he noted that regulatory and financing challenges slowed implementation. He added that the development of storage and generation capacity needs to progress in parallel, a challenge faced by many energy markets.

Private Capital Is Also Entering The Market

The state-backed battery installation forms part of a broader expansion of energy storage capacity across Cyprus. Alongside the project managed by the transmission system operator, the Electricity Authority of Cyprus (EAC) and private developers are advancing their own investments.

Current figures show 36 applications for battery storage projects with a combined requested capacity of approximately 925MW. The EAC has submitted applications for storage facilities in Dhekelia and Moni with a combined capacity of 180MW, while private-sector projects exceeding 150MW have progressed through various stages of the approval process.

Grid Stability Comes First

According to Papanastasiou, the state-owned battery system will primarily serve grid stability and energy security objectives rather than operate as a commercial trading asset. The facilities will store electricity during periods of surplus generation and release it when demand rises or when supply pressures emerge.

Privately operated storage projects could also contribute to the market by storing lower-cost renewable electricity and dispatching it later when demand and prices are higher.

As renewable energy continues to account for a larger share of Cyprus’ electricity mix, storage infrastructure is expected to play an increasingly important role in balancing supply and demand, reducing curtailments, and improving the overall efficiency of the power system.
