Alphabet has joined the $3 trillion club.

Shares of the search giant jumped more than 4% on Monday, pushing the company into territory occupied only by Nvidia, Microsoft and Apple.

The stock got a big lift in early September from an antitrust ruling by a judge, whose penalties came in lighter than shareholders feared. The U.S. Department of Justice wanted Google to be forced to divest its Chrome browser, and last year a district court ruled that the company held an illegal monopoly in search and related advertising.

But Judge Amit Mehta decided against the most severe consequences proposed by the DOJ, which sent shares soaring to a record. After the big rally, President Donald Trump congratulated the company and called it “a very good day.”

Alphabet shares are now up more than 30% this year, compared to the 15% gain for the Nasdaq.

The $3 trillion milestone comes roughly 20 years after Google’s IPO and a little more than 10 years after the creation of Alphabet as a holding company, with Google its prime subsidiary.

CEO Sundar Pichai was named CEO of Alphabet in 2019, replacing co-founder Larry Page. Pichai’s latest challenge has been the surge of new competition due to the rise of artificial intelligence, which the company has had to manage through while also fending off an aggressive set of regulators in the U.S. and Europe.

The rise of Perplexity and OpenAI ended up helping Google land the recent favorable antitrust ruling. The company’s hopes of becoming a major AI player largely ride with Gemini, Google’s flagship suite of AI models.

The U.S. and China have reached a ‘framework’ deal for social media platform TikTok, Treasury Secretary Scott Bessent said Monday.

“It’s between two private parties, but the commercial terms have been agreed upon,” he said from U.S.-China talks in Madrid.

Both President Donald Trump and Chinese President Xi Jinping will meet Friday to discuss the terms. Trump also said in a Truth Social post Monday that a deal was reached “on a ‘certain’ company that young people in our Country very much wanted to save.”

Bessent indicated that the framework could pivot the platform to U.S.-controlled ownership.

TikTok did not immediately respond to a request for comment.

The comments came during the latest round of trade discussions between the U.S. and China. Relations have soured between the two countries in recent months from Trump’s tariffs and other trade restrictions.

At the same time, TikTok parent company ByteDance faces a Sept. 17 deadline to divest the platform’s U.S. business or face being shut down in the country.

U.S. Trade Representative Jamieson Greer said Monday that the deadline may need to be pushed back to get the deal signed, but there won’t be ongoing extensions.

Congress passed a law last year prohibiting app store operators like Apple and Google from distributing TikTok in the U.S. due to its “foreign adversary-controlled application” status.

But Trump postponed the shutdown in January, signing an executive order in January that gave ByteDance 75 more days to make a deal. Further extensions came by way of executive orders in April and in June.

Commerce Secretary Howard Lutnick said in July that TikTok would shutter for Americans if China doesn’t give the U.S. more autonomy over the popular short-form video app.

As for who controls the platform, Trump told Fox News in June that he had a group of “very wealthy people” ready to buy the app and could reveal their identities in two weeks. The reveal never came.

He has previously said he’d be open to Oracle Chairman Larry Ellison or Tesla CEO Elon Musk buying TikTok in the U.S. Artificial intelligence startup Perplexity has submitted a bid for an acquisition, as has businessman Frank McCourt’s Project Liberty internet advocacy group, CNBC reported in January.

Trump told CNBC in an interview last year that he believed the platform was a national security threat, although the White House started a TikTok account in August.

In a sweeping interview last week, OpenAI CEO Sam Altman addressed a plethora of moral and ethical questions regarding his company and the popular ChatGPT AI model.  

“Look, I don’t sleep that well at night. There’s a lot of stuff that I feel a lot of weight on, but probably nothing more than the fact that every day, hundreds of millions of people talk to our model,” Altman told former Fox News host Tucker Carlson in a nearly hour-long interview. 

“I don’t actually worry about us getting the big moral decisions wrong,” Altman said, though he admitted “maybe we will get those wrong too.” 

Rather, he said he loses the most sleep over the “very small decisions” on model behavior, which can ultimately have big repercussions.

These decisions tend to center around the ethics that inform ChatGPT, and what questions the chatbot does and doesn’t answer. Here’s an outline of some of those moral and ethical dilemmas that appear to be keeping Altman awake at night.

According to Altman, the most difficult issue the company is grappling with recently is how ChatGPT approaches suicide, in light of a lawsuit from a family who blamed the chatbot for their teenage son’s suicide.

The CEO said that out of the thousands of people who commit suicide each week, many of them could possibly have been talking to ChatGPT in the lead-up.

“They probably talked about [suicide], and we probably didn’t save their lives,” Altman said candidly. “Maybe we could have said something better. Maybe we could have been more proactive. Maybe we could have provided a little bit better advice about, hey, you need to get this help.” 

Last month, the parents of Adam Raine filed a product liability and wrongful death suit against OpenAI after their son died by suicide at age 16. In the lawsuit, the family said that “ChatGPT actively helped Adam explore suicide methods.”

Soon after, in a blog post titled “Helping people when they need it most,” OpenAI detailed plans to address ChatGPT’s shortcomings when handling “sensitive situations,” and said it would keep improving its technology to protect people who are at their most vulnerable. 

OpenAI was one of the AI companies that received a $200 million contract from the U.S. Department of Defense to put generative AI to work for the U.S. military. The firm said in a blog post that it would provide the U.S. government access to custom AI models for national security, support and product roadmap information.
