Asian shares and US futures rise as AI earnings revive tech optimism

Asian shares and US equity futures rose Wednesday as strong earnings from major AI beneficiaries revived optimism in the tech sector. The MSCI Asia Pacific Index climbed 0.9%, while the Kospi Index jumped 3% on gains from chipmakers SK Hynix and Samsung Electronics. SpaceX reported net income more than double estimates, sending shares up 8% in extended trading, while Super Micro Computer surged 15% after topping expectations. These results helped ease concerns over AI valuations that rattled markets last week, lifting Nasdaq 100 futures by 1%. Attention now turns to upcoming earnings from Meta Platforms and Tesla, due Wednesday, to gauge whether growth justifies massive AI infrastructure spending. Meanwhile, billionaire Ken Griffin warned investors are "almost certainly" in an AI bubble, though analysts note demand shows no signs of slowing.
