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.

Irregular Meal Timing May Raise Heart Risk In Men, New Study Suggests

Eating breakfast at lunchtime or dinner during normal sleeping hours may seem like a minor weekend indulgence. New research suggests, however, that this type of irregular meal timing, described by scientists as “eating jet lag,” may be linked to higher cardiovascular risk in men.

A French study published in Communications Medicine found that each additional hour of eating jet lag was associated with a 14% higher risk of cardiovascular disease and a 21% higher risk of coronary heart disease among men. No similar association was observed in women.

Why Meal Timing Matters

Weekend schedules often differ from weekday routines, with work and school timetables shifting when people eat. Over time, researchers suggest, these changes may interfere with the body’s biological rhythms.

“This study suggests the importance of regular meal-timing patterns, beyond sleep and diet quality, in cardiovascular disease prevention,” the authors wrote.

Researchers followed more than 100,000 participants for 14 years, analyzing the timing of their first and last meals on working days and weekends between 2009 and 2023.

Risk Pattern Appeared In Men

Participants were grouped according to how their meal times changed between weekdays and weekends. One group ate earlier on weekends, another maintained similar schedules, and a third ate later.

Both groups with irregular meal timing showed higher cardiovascular risk than those with stable schedules, regardless of overall diet quality. The association was observed only among men.

Researchers proposed several possible explanations. Men generally have a higher absolute risk of cardiovascular disease, while women tend to have stronger morning-oriented routines that may influence how their bodies respond to changes in meal timing.

Circadian Rhythms May Explain The Link

One possible explanation is that irregular eating disrupts the body’s circadian system, which regulates many physiological functions over a 24-hour cycle.

Light is the main signal that sets circadian rhythms, but food timing also helps synchronize peripheral clocks in organs including the liver and heart. Eating in alignment with these rhythms is generally associated with better metabolic regulation, while irregular timing may disrupt that balance.

What It Means For Prevention

The findings do not prove that irregular meal timing causes heart disease. However, they add to growing evidence that when people eat may matter nearly as much as what they eat for long-term cardiovascular health.

If confirmed in larger studies, regular meal timing could become a useful target for public health interventions aimed at reducing chronic disease risk. For individuals, employers and schools, greater consistency in daily routines may be more than a lifestyle preference and could form part of a broader strategy to protect heart health.
