On Wednesday, NVIDIA, the top stock by trading volume in the U.S. market, closed up 1.37% with a trading volume of $32.838 billion. NVIDIA's CEO Jensen Huang hopes employees will use artificial intelligence (AI) as much as possible, insisting that they need not worry about losing their jobs in the process. According to a leaked recording, Huang stated at last week's all-hands meeting, &#34;As far as I know, some managers at NVIDIA actually instructed employees to use AI less. Are you crazy?&#34; Huang expressed strong opposition to this practice. &#34;I want every task that can be automated through AI to be automated,&#34; Huang said, &#34;I assure you, you will still have work to do.&#34;Tesla, the second highest, rose 1.71% with a trading volume of $26.396 billion. The new version of Tesla's Robotaxi App has been revealed, featuring in-car camera data sharing, suggesting the elimination of safety drivers. With user consent, Tesla can access in-car video and audio data for remote customer service to monitor passenger status.Additionally, data from the European Automobile Manufacturers Association shows that Tesla is facing global sales pressure, with October sales in the European market plummeting 48.5% year-on-year, and sales in the region down about 30% year-to-date, while the overall industry's electric vehicle sales surged by 26%.Google's Class A shares, ranked third, fell 1.08% with a trading volume of $16.303 billion. Morgan Stanley released a research report on Wednesday titled &#34;What Google's External Sales of TPU Means for the Semiconductor Industry,&#34; focusing on a topic currently generating much discussion on Wall Street.The firm believes that in an environment where NVIDIA sells about 8 million chips annually, TPU is expected to achieve annual sales of 500,000 to 1 million units. Each sale of 500,000 TPUs would increase Google's cloud business revenue by about 10% in 2027, boost earnings per share by 3%, and drive up valuation multiples. The firm believes this event is directly beneficial to Broadcom, but has limited actual impact on NVIDIA, despite sparking significant discussion within the industry.Morgan Stanley believes that Google has about 12 years of innovation accumulation in the TPU field, and its current push to sell to external markets marks further expansion of its business.Broadcom, ranked fifth, rose 3.26%, reaching an all-time high with a trading volume of $11.094 billion.Meta Platforms, ranked ninth, fell 0.41% with a trading volume of $9.196 billion. Recently, it was reported that Meta is considering spending billions of dollars to purchase Google's TPU, including for the construction of Meta's data centers.Traditionally, Google has only deployed its self-developed TPUs in its own data centers and rented computing power to customers. This potential deal could allow Google to capture 10% of NVIDIA's annual revenue, bringing in billions of dollars in new revenue, and some leaders in Google's cloud division have expressed this goal internally.AMD, ranked tenth, rose 3.93% with a trading volume of $9.135 billion. Morgan Stanley noted in a report released on Wednesday that there is a significant difference in gross margins within the chip industry, with NVIDIA at about 75% and AMD at about 50%Robinhood Securities, ranked 12th, rose by 10.93%, with a trading volume of $5.875 billion. The company announced on Wednesday that it will expand its fastest-growing product line: the prediction market business.The online brokerage announced a partnership with market maker Susquehanna International to launch a futures and derivatives exchange to enhance its prediction market services (where users can bet on the outcomes of various events such as sports results and Federal Reserve interest rate decisions). Following the announcement, its stock price surged.Robinhood first launched its prediction market service last year in collaboration with Kalshi. According to Robinhood, over 1 million users have traded 9 billion contracts since the service went live.Bernstein analysts stated on Wednesday that Robinhood is likely to continue distributing Kalshi's products, but this new initiative will allow it to directly supplement more event contracts.Oracle, ranked 14th, rose by 4.02%, with a trading volume of $5.268 billion. Deutsche Bank Securities published a research report refuting bearish views on AI spending. The firm stated that even in adverse conditions, Oracle's long-term earnings per share and cash flow would only be slightly affected.Taiwan Semiconductor Manufacturing Company (TSMC), ranked 16th, rose by 1.85%, with a trading volume of $3.453 billion. TSMC confirmed on Tuesday (25th) that it has formally filed a lawsuit against former senior vice president Luo Weiren, claiming he violated his employment contract, non-compete agreement, and relevant provisions of the &#34;Trade Secrets Act.&#34; TSMC believes that Luo is highly likely to use or leak, inform, deliver, or transfer the company's trade secrets and confidential information to Intel, prompting the company to take legal action, including breach of contract compensation
