最新报道:Nvidia (NVDA) shares surged as OpenAI's valuation hit $500 billion, becoming the world's most valuable startup after a $6.6 billion secondary share sale involving SoftBank and MGX. The AI firm's massive investments—including a $300 billion computing deal with Oracle and $10 billion chip partnership with Broadcom—boost Nvidia's growth prospects, with analysts predicting over $40 billion annual ad revenue potential. However, antitrust concerns from the DOJ could impact NVDA, which has gained 6% weekly and 40% YTD, with Bernstein's $225 target reflecting optimism.
