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 Could Tighten Short-Term Rental Rules Under New EU Housing Framework

Cyprus could gain a stronger legal basis to restrict Airbnb-style rentals in areas facing housing pressure, but any measures would need evidence showing where that pressure exists and how short-term rentals contribute to it.

The European Commission’s forthcoming Affordable Housing Act is still being drafted and would not impose an EU-wide cap or ban. Instead, it would allow authorities to identify “areas of housing stress” using public data and introduce proportionate measures, including restrictions on short-term lets, alongside policies to increase housing supply.

Cyprus’ Short-Term Rental Market Is Growing

Eurostat data shows Cyprus recorded 7.64 million guest nights booked through Airbnb, Booking and Expedia in 2025, up 24.7% from 2024. During the first quarter of 2026, platform guest nights exceeded one million, a 22.3% year-on-year increase and the EU’s fourth-fastest growth rate.

Guest-night figures measure demand rather than the number of homes used for short-term rentals, so they do not show how many properties may have left the long-term rental market.

Registration Gaps Remain

A July Audit Office report said 8,464 licensed self-service accommodation units were registered as of May 6. That compares with 492,931 housing units in the 2021 census, although the figures are not directly comparable.

An audit of 20 online listings found only six with valid licences matching state records. Ten had no registration number, while four displayed invalid or mismatched numbers. A separate review of 150 listings in Famagusta found 23 properties absent from the relevant registers.

The samples cannot establish the scale of illegal rentals nationwide, but they indicate gaps in registration and enforcement.

EU Framework Focuses On Data

Regulation 2024/1028, effective since May 20, creates a common EU framework for collecting data from hosts and platforms. Platforms can be required to display registration numbers, conduct checks and provide authorities with data on stays, nights booked and individual properties.

The regulation does not impose rental limits. It is intended to give authorities evidence for deciding whether further restrictions are justified.

Property Prices Have Other Drivers

Cyprus residential property prices rose 7.5% year on year in the first quarter of 2026, according to the Central Bank of Cyprus. Apartment prices increased 10.8%, while house prices rose 3%.

The central bank attributed the increase primarily to foreign demand, followed by domestic demand and higher construction costs. It did not identify short-term rentals as the main cause.

The European Commission’s housing assessment found short-term rental activity across the EU increased 93% between 2018 and 2024. While listings account for an estimated 1.2% of total housing stock, their share can reach 20% in some tourist centers and neighborhoods.

The Commission said high concentrations of short-term rentals do not automatically cause housing shortages or higher prices, although they can add pressure where supply is already constrained.

Local Evidence Will Shape Any Restrictions

A 2020 EU court ruling found that a shortage of long-term rental housing can justify prior-authorisation rules for short-term lets if measures are necessary, nondiscriminatory and proportionate. Airbnb has supported better data sharing while calling for targeted rather than blanket restrictions.

For Cyprus, any case for tighter rules will therefore depend on neighborhood-level evidence linking short-term rentals to local housing pressure. In 2024, 2.4% of Cyprus residents faced housing-cost overburden, compared with 8.2% across the EU, according to Eurostat.
