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.

China’s market regulator on Monday said that Nvidia violated the country’s anti-monopoly law, according to a preliminary probe, adding that Beijing would continue its investigation into the U.S. chip giant.

Shares of Nvidia were down around 2% in premarket trading.

Late last year, China’s State Administration for Market Regulation (SAMR) opened an investigation into Nvidia in relation to the acquisition of Mellanox and some agreements made during the acquisition. Nvidia acquired the Israeli technology company that creates network solutions for data centers and servers in 2020, in a deal that was approved by China at the time with certain conditions.

In a preliminary investigation, the SAMR said Nvidia had violated China’s anti-monopoly laws in relation to that acquisition and its conditions. China’s market regulator did not specify how Nvidia allegedly breached the country’s laws.

CNBC has reached out to Nvidia for comment.

The update from the SAMR has the potential to complicate trade talks between Chinese and U.S. officials that began on Sunday in Madrid, Spain.

Tensions between Beijing and Washington appear to be on the rise on the technology front. China opened two separate probes into semiconductors on Saturday: one is an anti-dumping investigation into certain chips imported from the U.S., while the other is an anti-discrimination scrutiny of U.S. restrictions on China’s chip industry.

After Swedish payments group Klarna’s $17 billion initial public offering, investors are pondering which big fintech name will be the next to go public.

Klarna popped as much as 30% on the day of its New York IPO, before settling to close around 15% higher. The stock declined further to $42.92 by Friday but is still up about 7% from its IPO price of $40.

The debut demonstrated how Wall Street is becoming more welcoming of bumper fintech listings. Prior to Klarna, online trading platform eToro, stablecoin issuer Circle and crypto exchange Bullish all went public to a positive first-day reception.

Gemini, the crypto exchange founded by Cameron and Tyler Winklevoss, surged 14% in its IPO Friday.

“I think the Klarna IPO would be viewed positively by some of the other scaled-up vendors,” Gautam Pillai, head of fintech research at British investment bank Peel Hunt, told CNBC.

There’s a crowded pipeline of fintech names that could be next to IPO after Klarna. CNBC looks at which companies look the most promising.

Ultimately, Stripe in January opted for a secondary share sale valuing the company at $91.5 billion — close to its peak valuation of $95 billion, which it achieved in 2021.

That doesn’t mean Stripe couldn’t still pursue a stock market debut further down the line. Many fintech unicorn CEOs have been keeping a close eye on Klarna’s IPO performance for signs of when will be the right moment to list.

Co-founder and CEO Nikolay Storonsky has spoken candidly about his preference to list in the U.S. due to issues with London’s IPO market. Last year, he told the 20VC podcast that it was “just not rational” to go public in the U.K.

Having recently reached a $5.9 billion valuation in a secondary share sale, British digital bank Monzo is another contender for the public markets.

A report surfaced earlier this year from Sky News that said Monzo had lined up bankers to work on an IPO that could take place as early as the first half of 2026.

However, in a fireside discussion moderated by CNBC at SXSW London, Monzo CEO TS Anil said that an IPO is “not the thing we’re focused on right now” — it’s worth noting though that this was back in June.

“The thing we’re focused on is scale the business, continue to grow it, double it again, reach more customers, build more products, continue to drive great economic outcomes on the back of that,” Anil said at the time.

Anil wouldn’t comment on where Monzo would list if it were to IPO, but he stressed the firm was “deeply committed” to being globally headquartered in London. 

On Thursday, Bloomberg reported that Starling had hired Jody Bhagat, former president of global banking at software firm Personetics Technologies, to lead the growth of its Engine technology unit in the U.S.

Starling declined to comment when asked by CNBC about its listing plans.

Last year, Starling’s CEO Raman Bhatia talked up the bank’s plans to expand globally via Engine, a software platform that Starling sells to other companies so they can set up their own digital banks.

“I am very bullish about this approach around internationalization of what is the best of Starling — the proprietary tech,” Bhatia said during a fireside chat at the Money 20/20 conference moderated by CNBC.

Starling was last privately valued at £2.5 billion ($3.4 billion) in a 2022 funding round. However, reports indicate the firm is looking to fetch a valuation of £4 billion in an upcoming secondary share sale.

The spend management platform was valued at $1 billion in 2022 and saw revenue surge 85% year-over-year in 2024 to 23.4 million euros ($27.4 million).

“We’re definitely seeing the IPO window open,” Payhawk CEO and co-founder Hristo Borisov told CNBC in an interview earlier this month. However, he stressed that “we are looking at more of a five-year horizon there.”

“If you look at the majority of the IPOs, the majority of those IPOs are companies with $400 million to $500 million-plus ARR [annual recurring revenue],” Borisov said. “That’s our goal.”

Blockchain firm Ripple’s CEO Brad Garlinghouse told CNBC in January last year that the company explored markets outside the U.S. for its IPO due to an aggressive crypto enforcement regime under ex-Securities and Exchange Commission chief Gary Gensler.

That could change now thanks to President Donald Trump’s pro-crypto stance. Garlinghouse said last year though that Ripple had put any plans for an IPO on hold. The startup was most recently valued at $15 billion.

Germany’s N26 is another potential IPO contender. The digital bank was valued at $9 billion in a 2021 funding round.

However, it has faced some setbacks. N26 co-founder Valentin Stalf recently stepped down as CEO after facing pressure from investors over regulatory failings.
