Markets are digesting the tech rout on Wall Street with the Nasdaq Composite index falling 2.6% for its worst day since early July on renewed doubts over AI spending.

In Seoul, SK Hynix shares rebounded 2.6% after the company scrapped plans for a U.S. listing of its Solidigm unit, recovering from an early dip below 1.2 million won ($905). Regulators had said the plan ran afoul of dual-listing rules, and SK Hynix cited market conditions while saying it will keep exploring financing for a new U.S. fab.

Elon Musk's empire was also in focus. President Donald Trump called Musk and asked him to lift restrictions that had slowed Ukraine's use of Starlink and hampered its drone operations, the Wall Street Journal reported. Trump said access has been restored, though Ukrainian President Volodymyr Zelenskyy said speeds aren't fully back.

SpaceX booked a $561 million unrealized gain on its stake in Musk's Boring Co. in the third quarter, lifting net income to about $4.4 billion. The non-cash markup followed a September Boring fundraising round, and SpaceX still shows a $413 million net loss for the first nine months.

Musk is also spending heavily on politics, putting about $366 million into this election cycle, including $276 million since July, mainly to keep Republicans in control of Congress, according to the New York Times. That likely makes him the largest single donor in this year's races, and House Democrats have already called for investigations into SpaceX's government contracts.

Back in tech, Nvidia CEO Jensen Huang said neocloud demand is "off the charts." He told CNBC at GTC in Berlin that "the demand of the capital is much greater than the availability of the capital," though he expects the gap to be solved.

Money is moving the other way for China's wealthy, who are shifting offshore funds into U.S. banks as Beijing widens its tax net, with private bankers and lawyers reporting a jump in inquiries since July. Beijing set an Oct. 22 deadline to declare offshore trust income, taxed at 20%.

In Japan, core inflation rose to 2.1% in September from 1.7% in August, the highest this year and above the Bank of Japan's 2% target. The reading matched forecasts, with the Bank of Japan expected to hold at next week's meeting and a December hike still in play.
