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

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%).

Pinterest Shares Surge on Strong AI Ad Forecasts

Pinterest’s stock soared by 20% on Friday after the company raised its first-quarter revenue forecast, indicating that its AI-driven advertisement tools will boost ad spending on the platform. The surge was driven by Pinterest’s prediction of revenue exceeding expectations, with a focus on its direct response ads, which encourage actions like app downloads or website visits.

CEO Bill Ready highlighted the success of Pinterest’s AI tools, particularly the Performance+ suite, which automates ad targeting and reduces the inputs required for campaign creation. This has been especially helpful for smaller advertisers. “Advertisers using these tools now need 50% fewer inputs to create a campaign,” Ready explained.

Bernstein analyst Mark Shmulik noted that automating the ad creation process makes Pinterest an appealing choice for advertisers, particularly smaller ones, due to the ease it offers. Shmulik also expressed confidence that Pinterest’s progress is sustainable.

In the fourth quarter, Pinterest reported record revenue, driven by strong ad spending from the retail, technology, and financial services sectors. However, advertising spend from food and beverage companies remained weak. Following the positive earnings report, at least 27 brokerages raised their price target for Pinterest.

The company’s first-quarter revenue projection of $837 million to $852 million exceeds analysts’ consensus estimate of $832.8 million. Additionally, its adjusted core earnings forecast of $155 million to $170 million also surpassed expectations.

Pinterest’s stock value could increase by over $4 billion if the gains hold, with the company’s market valuation currently sitting at $22.70 billion. Despite volatility in stock price following earnings reports, Pinterest’s outlook remains positive, with its first-quarter projections further fueling investor optimism.

Couche-Tard’s Bid for 7-Eleven Seen as Strategic Move for ‘Cheap’ Stock, Amid Regulatory Concerns

Alimentation Couche-Tard’s recent bid to acquire 7-Eleven’s parent company, Seven & i Holdings, has sparked discussions within the financial world about the strategic motives behind the deal. According to industry analysts, the Canadian retail giant, which operates Circle K, views Seven & i as an undervalued stock, making it an attractive target for acquisition. Richard Kaye, a portfolio manager at Comgest, remarked that despite Seven & i’s robust core business, Couche-Tard likely sees an opportunity for a financially advantageous acquisition.

The acquisition, if successful, would be one of the largest foreign takeovers of a Japanese company. Although the offer amount remains undisclosed, U.S. investment firm Artisan Partners Asset Management has urged Seven & i to seriously consider the buyout offer. The move comes as the Japanese conglomerate is undergoing a restructuring process aimed at expanding 7-Eleven’s global reach and divesting from its underperforming supermarket divisions.

Despite Couche-Tard’s strong financial position, with a valuation of $54 billion compared to Seven & i’s $38.3 billion, the deal faces significant regulatory challenges. Particularly, antitrust scrutiny is anticipated in both the U.S. and Japan, given the size and scope of the companies involved. Retail analyst Bryan Gildenberg commented that regulatory approval may require divestments to address competition concerns, especially in the U.S. market.

Picture background

In Japan, Seven & i is reportedly seeking designation as a “core” company under the country’s Foreign Exchange and Foreign Trade Act, which could complicate the acquisition. This designation would subject the transaction to heightened scrutiny by Japan’s finance ministry, reflecting concerns about potential disruptions to 7-Eleven’s well-established convenience store model, known as “konbini” in Japan.

While Couche-Tard’s interest in Seven & i stems from the Japanese firm’s perceived undervaluation, the deal also highlights a broader trend of global companies seeking undervalued opportunities within Japan’s stock market. Kaye noted that despite the strong operational performance of companies like Seven & i, Fast Retailing, and Pan Pacific International Holdings, they trade at lower valuations than their global counterparts, making them attractive investments for firms like Couche-Tard.

However, the potential regulatory roadblocks and the preservation of Seven & i’s unique business model remain key challenges in completing the deal. If successful, the acquisition could reshape the global convenience store landscape and further expand Couche-Tard’s footprint beyond North America, into one of the world’s largest retail markets.
