Investors shrug off AI safety concerns and Iran war, sending market to a new peak.

Wall Street’s Nasdaq stock exchange has hit an all-time high, shrugging off concerns about AI safety risks, sky-high tech valuations and the energy shock caused by the United States’ war on Iran.

The Nasdaq Composite index, which is dominated by US tech giants such as Nvidia, Apple and Microsoft, rose 0.45 percent on Tuesday, taking its gains to date this year to more than 17 percent.

The Nasdaq 100, a narrower index that tracks 100 top companies, jumped 0.82 percent.

The S&P 500, the most popular measure of the overall US stock market, closed essentially flat.

Monolithic Power Systems, a Florida-based manufacturer of power circuits, and Canadian e-commerce company Shopify led the gains, surging 8.1 percent and 7.1 percent, respectively.

Micron Technology, one of the world’s top three memory chip makers along with South Korea’s SK Hynix and Samsung Electronics, rose 5 percent.

Chip giant Nvidia, the world’s most valuable company, gained 0.7 percent, while Apple edged up 0.2 percent.

Meta Platforms, which soared 11.4 percent on Monday on excitement surrounding its new AI assistant Muse, dropped 0.63 percent.

Major Asian stock markets opened higher on Wednesday, with Japan’s benchmark Nikkei 225 and South Korea’s Kospi up about 1.4 percent and 0.1 percent, respectively, in morning trading.

Hong Kong’s Hang Seng Index opened lower, falling more than 0.7 percent during the morning trade.

Oil prices were largely flat on Tuesday, after falling more than 3 percent the previous day amid improving oil flows out of the Gulf and hopes of renewed diplomacy between Washington and Tehran.

Futures for Brent crude, the international benchmark, were trading at $99.18 a barrel as of 01:00 GMT.

⁠US President Donald Trump on Tuesday told reporters that US officials ‌held a “very good” meeting with their Iranian counterparts on the sidelines of the United Nations General Assembly in New York, hours after using his address to the session to warn that he could “annihilate” Iran if Tehran did not agree to a deal on the war.

Trump, whose war on Iran is nearing the seven-month mark, said US and Iranian officials would hold another round of talks in the “very near future”.

Jay Goldberg, a senior analyst at Seaport Research Partners in San Francisco, said signs of diplomatic progress between the US and Iran had refocused investor attention on the potential of AI to generate profits after years of multibillion-dollar investments.

“We have been searching for a clear consumer use case to justify the AI spend, and many see Muse as just that product,” Goldberg told Al Jazeera.

“Personally, I think Muse is just a step in the right direction; there will be better products – probably soon – but Muse is one of those things that are so useful they get investors excited about AI prospects again,” Goldberg said.
