Nvidia (NVDA 1.86%) has been one of the biggest beneficiaries of the artificial intelligence (AI) boom. Shares have already soared by more than 1,300% in the past five years. However, the next big AI stock gains may come from less obvious players. As AI infrastructure spending expands, demand is rising not just for AI chips but also for high-speed connectivity technologies that enable the movement of massive amounts of data between servers and across data centers. Against this backdrop, here's why these three AI-powered tech stocks are worth watching for a potential Nvidia-style run in the coming years. Astera Labs Astera Labs (ALAB +3.19%) designs high-speed connectivity chips and hardware that enable AI chips, servers, and memory to communicate efficiently within modern data centers. AI spending is increasingly shifting away from training large models toward running AI applications at scale. Subsequently, demand for connectivity solutions that enable faster and more efficient data movement across data centers is also growing significantly. Astera is well-positioned to capitalize on this opportunity. Expand NASDAQ : ALAB Astera Labs Today's Change ( 3.19 %) $ 9.51 Current Price $ 307.35 Key Data Points Market Cap $53B Day's Range $ 300.00 - $ 315.75 52wk Range $ 84.78 - $ 315.81 Volume 348.9K Avg Vol 5.4M Gross Margin 75.99 % Astera's recent financials highlight its growing momentum.

Management now expects Q2 revenue in the range of $355 million to $365 million, up 15% to 18% sequentially. Astera has already shipped millions of PCIe Gen 6 ports, high-speed connections that help move data quickly between AI chips, memory, and servers.

The US has launched strikes on southern Iran in a test of the seven-week long ceasefire, as both sides played down hopes for an imminent peace deal even as negotiators from Tehran began new talks in Qatar. US forces targeted missile launch sites and boats attempting to lay mines, US central command (Centcom) said on Tuesday, but stressed that the strikes did not indicate the ceasefire with Iran was over. Centcom “continues to defend our forces while using restraint during the ongoing ceasefire”, said navy captain Tim Hawkins, who characterised the action as “defensive”. In Iran, the news website Tabnak, believed to be close to former Revolutionary Guard chief Mohsen Rezaei, identified four dead Guard troops it said had been killed in American strikes on boats. Iranian state television separately reported blasts around Bandar Abbas, a city on the Strait of Hormuz home to a military port and a dual-use airport. The Iranian state news agency Mehr later said the situation was “completely under control” and there was no reason for residents to worry. The strikes – the second major attacks to take place during the seven-week ceasefire – came as Mohammad Bagher Ghalibaf, the speaker of Iran’s parliament, led a delegation of negotiators to Qatar. Local media said Iran’s foreign minister, Abbas Araghchi, and central bank governor, Abdolnaser Hemmati, were among the group as well. Hemmati’s presence has fuelled speculation that talks will focus on the release of frozen Iranian assets. The deal currently under negotiation with the US would reportedly see Washington agree to unfreeze some Iranian assets being held in banks outside Iran – including Qatar. Trump has faced criticism from loyalists in his party over the reports that billions of dollars in frozen assets could be made available to Tehran, with senior Republican saying the reported details of the peace deal appear too close to the nuclear deal negotiated in 2015 by the Obama administration, which Trump pulled out of. ...

Huawei targets 1.4-nanometer chip performance by 2031 Huawei Technologies Co. Ltd. expects to match the performance of industry-leading 1.4-nanometer chips by 2031 using a novel design architecture, signaling a major step in bypassing U.S. curbs on its access to advanced manufacturing tools. He Tingbo, president of the company’s semiconductor division, unveiled the Tau (τ) Scaling Law at an international symposium on Monday. The new theoretical framework focuses on minimizing signal transmission time across vertically stacked chip layers rather than shrinking the physical size of transistors. Under the new approach, Huawei’s upcoming Kirin processors, due this autumn, will feature “LogicFolding” technology. By vertically stacking digital, analog, and memory circuits, the method shortens transmission paths and reduces resistance, allowing chips to operate more efficiently on older manufacturing nodes.

China Begins Flooding The Market With DRAM And NAND Memory Chips Last September, when the memory bubble was just getting started, we said that inevitably " the cure for high commodity prices is, well, high commodity prices." While many financial market maxims have quietly ceased working in recent years thanks to rigged markets due to central bank interventions and market manipulation by both money printers and HFTs, this is one that will never fail, the only question is timing. Furthermore, there is one other thing that can be added as an ironclad footnote here, and that is that once China starts producing the commodity in question, what was formerly price euphoria quickly turns to collapse ( as history so vividly demonstrates when looking at any of China's export markets, where price dumping always unleashes hell for domestic producers). Well, for memory chips, that time has finally come. You mean commodity DRAM prices won’t go to infinity? https://t.co/islKPtFQY2 — zerohedge (@zerohedge) May 22, 2026 According to Tom's Hardware , Wccftech and techspot , Chinese semiconductor firms have begun flooding the market with domestically produced DRAM and NAND chips in a move that analysts say will drive down memory and storage prices , offering consumers some much-needed relief. Reports suggest that several leading global PC component manufacturers have already started using the chips in upcoming products. According to screenshots posted on X by tipster @wxnod, Corsair has integrated memory chips manufactured by Chinese DRAM maker ChangXin Memory Technologies (CXMT) into its next-generation memory modules. While Corsair typically sources memory chips from Micron Technology, elevated market prices have reportedly pushed the company to explore more cost-effective alternatives .

Chinese shares listed in Hong Kong rose after returning from a holiday, as investors brushed aside Beijing’s most forceful crackdown on illicit cross-border stock trading to chase tech gains. The Hang Seng China Enterprises Index advanced as much as 0.9%, with Lenovo Group Ltd. and Semiconductor Manufacturing International Corp. leading the gains. A Bloomberg gauge of Hong Kong-listed brokerages also jumped 3.3%. Tuesday’s upbeat tone was lifted by optimism over Huawei Technologies’ near breakthrough in advanced production. That’s in contrast to the 2.2% slide in the Nasdaq Golden Dragon China Index on Friday after authorities threatened penalties against popular brokers and ordered non-compliant accounts to be liquidated in two years in measures announced after local markets shut. Sentiment was steadier when Hong Kong markets reopened on Tuesday, as investors bet a gradual unwind and the option to shift accounts to local brokers would keep liquidity and funds within the system. The extended timeline along with the targeted scope of the curbs also offered some relief. “I think the crackdown is specific to cross-border online brokers,” said Vey Sern Ling , managing director at Union Bancaire Privee. “Investors should not be worried that this is a broader regulatory tightening in the tech or Internet space.” Analysts including Morgan Stanley and Citic Securities have said that the financial impact from the measures is manageable. The crackdown is estimated to affect as much as HK$250 billion ($32 billion) of assets in Hong Kong, but the assets are spread across different products, and any equity selling would probably happen gradually, according to Citic. Still, the moves mark China’s most aggressive attempt yet to curb citizens’ access to overseas markets, a long-running but prohibited practice in a country with strict capital controls to protect its currency. The Hong Kong stock market’s strong performance in the last two years — the HSCEI gauge jumped more than 50%...

Globalism Seeks To Kill The Nation-State Authored by J.B. Shurk via American Thinker , International government threatens the whole planet. People are beginning to understand that those who rule in their name have long been working to eliminate the nation-state. The United Nations is not neutral ground for national governments to discuss their differences; it is a governmental construct meant to replace national governments. The World Health Organization is not an international body meant to coordinate complex responses to global health emergencies; it is an institution vested with vast power and authority to track and regulate every human on the planet. The Bank for International Settlements, the World Bank Group, and the International Monetary Fund don’t exist to expand free trade, open markets, and assist developing nations; they exist to centralize control over all economic transactions in the world. The onslaught of “green new deal” laws in Canada, the United States, the United Kingdom, the European Union, Australia, and New Zealand have nothing to do with preserving the environment or “saving the planet”; they are part of a broader U.N. initiative to track every person’s so-called “carbon footprint” in order to monitor, tax, and regulate all human activity. The U.N.’s “climate reparations” policy has nothing to do with “justice” or “science”; it exists to justify the redistribution of wealth from Western nations to non-Western nations under the guise of “international law.” The message we have heard all our lives is loud and clear: Nations do bad things. International organizations do good things. The rhetorical war on “nationalism” didn’t begin because people who are proud of their nations magically became Nazis; people who are proud of their nations are called “Nazis” so that those who rule over us can demonize the nation-state. If you go back through newspapers and scholarly essays before WWII, “nationalism” and “patriotism” are used interchangeably. After ...

格隆汇5月26日｜日本央行副行长冰见野良三强调，在近期日本国债遭遇抛售之际，适时调整政策对于维持市场参与者信心至关重要。冰见野良三周二表示：“关于货币政策与长期利率，我们认为，针对未来经济、物价和金融状况，以适当节奏调整货币宽松程度，从而维持市场对通胀将得到适当控制的信心，是非常重要的。”此番讲话似乎暗示，日本央行对近期加息持开放态度。冰见野良三与日本央行行长植田和男等官员近期均强调，有必要对金融市场保持负责任的态度，而市场目前普遍预计日本央行将在下月会议上加息。与此同时，日本首相高市早苗上周则微妙地释放出希望日本央行维持政策稳定的信号，因为她正试图缓解伊朗战争对经济带来的冲击。冰见野良三表示：“日本央行将努力适当实施政策，以维持这种市场信心，并以可持续、稳定的方式实现价格稳定目标。”

Armstrong World Industries (AWI +0.17%) and Carlisle Companies (CSL +0.43%) possess elite, high-margin, cash-compounding financial profiles, but they frequently fly under the radar for mainstream or institutional investors. That's because they're boring -- in a good way. They make high-margin goods that most investors don't think much about. Armstrong makes acoustical ceiling tiles and mineral fiber wall panels. Carlisle makes single-ply thermoplastic roofing membranes and commercial building envelope insulation. Here are three reasons why I like each of these construction supply stocks. Armstrong gets stability with high renovation exposure One of the biggest misconceptions about building materials companies is that they are entirely at the mercy of volatile new construction starts. Armstrong breaks this mold cleanly because roughly 70% of its commercial revenue is tied to renovation and remodel work, rather than new buildings. This structural exposure to remodeling helps the company during economic slowdowns. Commercial properties regularly need ceiling and acoustical updates, even when new from-the-ground-up construction freezes.
