Nvidia passed Apple in market value on Tuesday, once again becoming the most valuable publicly-traded company in the world.

Shares of the chipmaker rose over 1% on Tuesday, and shares are up about 4% so far in 2025 after rising 171% in 2024 and nearly 239% in 2023, reflecting insatiable demand for the company’s artificial intelligence chips.

Meanwhile, Apple shares slid 4% on Tuesday. They’re now down 12% this year after gaining 30% in 2024. The iPhone maker has developed its Apple Intelligence suite of AI features for its phones and laptops, but its business doesn’t have the same level of exposure to the AI boom.

Nvidia has the vast majority of market share for graphics processing units, or GPUs, which have become essential for developing and deploying AI software such as OpenAI’s ChatGPT. While revenue growth has slowed, it still nearly doubled to $35.08 billion in the most recent quarter.

Apple was the first company to reach the $1 trillion, $2 trillion and $3 trillion market cap milestones. Nvidia previously passed Apple in June and then again in November.

On Tuesday, Nvidia had a market cap of about $3.4 trillion, versus Apple at $3.3 trillion.Microsoft is just behind them at $3.2 trillion. A major buyer of Nvidia’s GPUs. Microsoft said earlier this month that it expected to spend $80 billion on AI data centers in fiscal 2025.

In November, Nvidia joined the Dow Industrial Average, replacing Intel, and joining Apple and Microsoft in the blue-chip index.

Reddit shares rose over 7% to a record high Tuesday after Raymond James analysts raised their price target and reiterated their “strong buy” rating for the social media platform.

The company’s shares reached $191 during midday trading, topping a previous high of $182 on Jan. 6. Reddit shares passed $100 for the first time in late October after the company reported third-quarter financial results that beat Wall Street expectations.

Raymond James analysts said in a Tuesday note that they would raise their Reddit price target to $200 from $150, largely due to their “conviction” that Reddit can expand its business internationally.

The company is planning to attract more users outside its core U.S. market as it looks to expand its advertising business, Reddit Chief Operating Officer Jen Wong told CNBC in November. Reddit’s third-quarter sales, which are predominantly online advertising, rose 68% year-over-year to $348.4 million.

Reddit’s increase use of artificial intelligence to automatically translate its site text to different languages like Portuguese, French, Spanish, Philippines and German “should help improve local search rankings for Reddit and provide durable hypergrowth,” the Raymond James analysts wrote.

The company’s AI-translation efforts are key to its international expansion, Wong told CNBC in November. Reddit’s fastest-growing regions in regards to users include the U.K., the Philippines, India and Brazil, she said.

“That points to a lot of our future user growth opportunity definitely outside of the U.S. and local language,” Wong said. “Every language is an opportunity for another Reddit.”

The company also continues to be one of the top five most searched websites, the Raymond James analysts said, citing the SimilarWeb research firm. Reddit’s “authentic and uniquely moderated (community system) content” will help the company stay on top of search results, ultimately resulting in more Reddit users creating accounts, the analysts wrote.

Reddit makes more money on logged-in users who have accounts rather than logged-out users, who have been visiting the platform more often over the past year due to internal site improvements and a previous Google search algorithm change that favored “authentic” content.

The Raymond James analysts noted in a section on “risks” that Reddit could suffer from “unfavorable Google search algo updates” that push the site lower in search results and slower rates in converting those logged-out users into the more financially lucrative logged-in counterparts.

Oracle shares jumped 6% on Tuesday on reports that the software maker is involved in a joint venture with OpenAI and SoftBank to build artificial intelligence infrastructure in the U.S.

President Donald Trump, who returned to the White House on Monday, will announce the plans, CNBC has confirmed. CBS News was first to report on the deal. The plans call for $100 billion initially and as much as $500 billion over four years.

Oracle shares soared 58% in 2024, their best performance since 1999, boosting co-founder and chairman Larry Ellison’s net worth by over $75 billion. Ellison has connections to the White House, having hosted a fundraiser for Trump in 2020 and allied himself with Tesla CEO Elon Musk, who appeared at Trump’s inauguration on Monday after advising him for months.

Oracle is also the cloud infrastructure provider for TikTok, which went dark over the weekend in response to a law passed by Congress and signed by former President Joe Biden. TikTok said it was restoring service to U.S. users starting Sunday night.

Last year Oracle picked up cloud business from artificial intelligence startup OpenAI, which needs large numbers of Nvidia graphics processing units to train and run AI models for its ChatGPT assistant and other products.
