White House National Economic Council Director Kevin Hassett said data centers still have ample room to grow. According to Odaily, U.S. President Donald Trump respects communities that do not want data centers built in their areas.

According to Jin10, the U.S. Department of Energy said the Trump administration postponed a White House meeting of a technology group that includes Nvidia CEO Jensen Huang and Meta Platforms CEO Mark Zuckerberg.

Taiwan Semiconductor Manufacturing Co. (TSMC) is considering expanding into advanced memory chip production, including 3D DRAM. According to Odaily, The Information reported, citing two sources, that TSMC recently began planning production of the chips in response to a request from Nvidia, its largest customer. DRAM stores data for processors to use. Unlike conventional DRAM, which places memory cells in a single layer, 3D DRAM stacks the cells vertically to increase memory capacity. Samsung Electronics, SK Hynix and Micron Technology dominate memory chip manufacturing and are also developing 3D DRAM technology. A memory chip shortage driven by demand for AI hardware has pushed prices higher, prompting chip designers including Nvidia and Apple to seek additional supply sources. Apple raised prices for its devices earlier this year amid higher memory costs.

According to Jin10, Amazon has introduced a text-based shopping feature through Alexa that helps users search and compare products, track promotions and price changes, and let Alexa for Shopping complete purchases for them. The feature is currently rolling out to a small group of invited users in the United States, with wider availability expected in the coming weeks. The launch follows Amazon's recent move to block Meta's AI shopping agent Muse from accessing its e-commerce platform. In March this year, Amazon also won a court ruling barring Perplexity's Comet shopping agent from its platform, but a U.S. appeals court overturned the injunction in August, and the litigation is ongoing.

Ueno Bank, once presented as a fintech success story in Paraguay, collapsed after the Inter-American Development Bank (IDB) detected warning signs in 2025, according to Bloomberg. The collapse is shaking the country and threatening Santiago Peña.

Pershing Square CEO Bill Ackman said Tuesday that high leverage, increasingly speculative trading and sharp share-price swings have made him worry that the U.S. stock market is dysfunctional. According to Sina Finance, Ackman said the market felt chaotic every few days, with many stocks trading at prices that seemed illogical to him; while long-term investors could benefit from buying at unusually low prices, he said this was bad for the country. Ackman said markets had returned to “casino-like” trading, with leverage at one point reaching 95%. He said this environment was harmful to the economy and society and fueled sharp share-price volatility. He added that market mispricing created buying opportunities for his fund. Earlier this year, Pershing Square bought Microsoft during the “SaaS selloff,” Amazon when its shares fell after U.S. President Donald Trump introduced tariffs, and Alphabet amid sharp share-price swings following ChatGPT’s launch. Ackman warned of significant risks from daily leveraged products, perpetual futures and sports-betting-style trading, saying that investors who treat U.S. stocks as a way to get rich quickly could face disastrous consequences. Ackman said he was particularly bullish on Visa and Mastercard, which he called two of the world’s best businesses. He also favored streaming platform Netflix and disclosed a Netflix holding in August.

SK Hynix has established Hyaico, a U.S. AI investment subsidiary with up to $10 billion in planned commitments, and SK Group Chairman Choi Tae-won will serve as its chairman. According to Sina Finance, the chipmaker disclosed the entity's name and management structure in a filing with the U.S. Securities and Exchange Commission on Tuesday; when the plan was announced in January this year, the subsidiary was provisionally named AI Co. SK Hynix President Song Hyun-jong will be Hyaico's CEO. Its board will also include former SK Hynix Vice Chairman Park Sung-wook, SK Hynix CEO Kwak Noh-jung, and SK Telecom CEO Jeong Jae-hoon. Hyaico will operate through Solidigm, SK Hynix's U.S. NAND flash subsidiary, and invest in U.S. AI companies and infrastructure projects, including AI factories. The platform is intended to help SK Group expand beyond memory chips into the broader AI ecosystem and enable affiliated companies to share technology and business opportunities. Choi's leadership and the appointment of executives from the group's semiconductor and telecommunications businesses to the board reflect SK Group's plan to coordinate its AI investments. Hyaico will use a capital-call structure, with SK Hynix and other investors contributing in stages when suitable investment opportunities arise. The $10 billion is the maximum commitment, not an immediate investment. SK Hynix plans to account separately for Solidigm's existing storage business earnings and Hyaico's new AI investment returns. Dividends and profits from the NAND business will be returned to shareholders; the company has not disclosed details of the distribution arrangements. An SK Hynix representative said Hyaico would keep investment operations and profits clearly separate.
