Nvidia hits $4 trillion market cap, cementing tech’s dominance in stock market

/in /tarafından

Nvidia Corp’s remarkable rise to a $4 trillion market valuation highlights its pivotal role in the stock market and the broader technology sector. The AI chipmaker’s shares have surged roughly 1,350% since October 2022, with a 22% gain so far in 2025, outperforming the 6% rise of the S&P 500.

The milestone was reached during morning trading on Wednesday, about 13 months after Nvidia first hit the $3 trillion mark. This rapid appreciation has made Nvidia the largest single stock by market value in the S&P 500, where it now accounts for around 7.5% of the index—more than any other company.

Nvidia’s influence is even more pronounced in tech-heavy indexes like the Invesco QQQ Trust ETF and the Philadelphia Semiconductor Index, though it has a smaller presence in price-weighted indexes such as the Dow Jones Industrial Average.

Microsoft ($3.7 trillion) and Apple ($3.1 trillion) trail Nvidia but are closing in on the $4 trillion threshold, underscoring the dominance of tech giants. The top seven companies in the S&P 500—also including Amazon, Alphabet, Meta Platforms, and Broadcom—make up about one-third of the index’s total market value.

This surge illustrates the growing dominance of the technology sector, which now represents about one-third of the S&P 500’s market value, nearing levels last seen during the dot-com bubble peak in 2000.

Other standout tech stocks in 2025 include Microsoft (+19%), Oracle (+40%), and Palantir (+88%).

Apple Appeals €500 Million EU Fine Over App Store Restrictions

/in /tarafından

Apple has officially filed a lawsuit challenging a €500 million ($587 million) antitrust fine imposed by the European Commission, contesting claims it violated the Digital Markets Act (DMA). The tech giant submitted the appeal on Monday, the final day to do so, at the EU’s General Court, the bloc’s second-highest legal authority.

The Commission ruled in April 2025 that Apple had unlawfully restricted app developers from directing users to cheaper payment options outside the App Store, a practice viewed as anti-competitive under the DMA.

In a public statement, Apple argued that the decision “goes far beyond what the law requires,” adding that the imposed fine was “unprecedented” and that the Commission is now effectively mandating how we run our store. Apple said it changed its policies to avoid daily fines of up to €50 million, or 5% of its average global daily revenue.

Despite modifying its App Store rules last month to comply with EU regulations, Apple insists the changes were made under protest, calling the Commission’s stance “confusing for developers and bad for users.” The company maintains that its original policies were fair and necessary for maintaining quality and user safety within the App Store ecosystem.

The European Commission has begun gathering feedback from developers to assess whether Apple’s revised App Store practices meet the obligations of the DMA. A decision on whether further changes will be required is still pending.

The case represents a significant moment in the EU’s broader campaign to rein in the influence of Big Tech, using the DMA to challenge gatekeeper platforms like Apple, Meta, Google, and Amazon. It also marks one of the first major legal battles under the DMA framework, setting a precedent for how tech firms may operate across the EU going forward.

Apple AI Chief Ruoming Pang Departs for Meta’s Superintelligence Division

/in /tarafından

Apple’s top artificial intelligence executive Ruoming Pang has reportedly left the company to join Meta Platforms, according to Bloomberg News. Pang, who led Apple’s foundation models team, is set to join Meta’s newly launched superintelligence division with a multimillion-dollar annual compensation package.

The move is part of an intensifying talent war among tech giants vying for leadership in AI development. Meta CEO Mark Zuckerberg recently restructured the company’s AI initiatives into a new division named Meta Superintelligence Labs, which will be overseen by Alexandr Wang, the former CEO of Scale AI. Wang, now Meta’s Chief AI Officer, joined the company following Meta’s recent investment in Scale AI—an investment that valued the startup at $29 billion.

Both Apple and Meta declined to comment on the news when approached by Reuters.

Pang’s departure underscores the increasing competition for elite AI talent, as companies invest aggressively in building cutting-edge models and technologies. Meta, in particular, has become more assertive in recruiting high-profile AI leaders to accelerate its ambitions in large language models and advanced generative systems.
