AI Stocks Rally as CoreWeave and Super Micro Report Surging Demand for AI Infrastructure

US stocks: S&P 500 ends higher as CoreWeave results fuel AI optimism

US stock markets closed higher on Wednesday, driven by strong AI infrastructure company earnings. Mild inflation data reinforced expectations that the Federal Reserve will hold interest rates steady. CoreWeave and other AI firms reported upbeat quarterly results, boosting their stock prices. Data center operators and chipmakers also saw gains following positive company forecasts. Traders now anticipate a 62% chance of the Fed maintaining current interest rates next month. The S&P 500 and the Nasdaq ended higher on Wednesday, lifted by upbeat quarterly results from CoreWeave and other AI infrastructure firms, while mild inflation data reinforced bets that the U.S. Federal Reserve will hold interest rates steady ⁠in September. U.S. ⁠consumer prices barely increased in July as the cost of gasoline declined for a second straight month, while underlying inflation was benign, further reducing expectations of an interest rate hike from the Federal Reserve next month. "The numbers came in right in line. The market's reaction is slightly positive because the market was fearful it was going to come in worse than it did. You're seeing a market thinking that the Fed is not being pushed toward a rate ⁠hike," said Robert Pavlik, senior portfolio manager at Dakota Wealth in Fairfield, Connecticut. CoreWeave surged after the AI cloud company lifted its annual capital spending forecast and topped second-quarter earnings estimates.

US stocks: CoreWeave, Super Micro surge on signs of sustained AI buildout

CoreWeave and Super Micro have seen their stock prices soar to new heights amid a rising tide of demand for AI infrastructure. CoreWeave has updated its expectations for annual revenue and operating profit, signaling strong market confidence. Similarly, Super Micro's projections for 2027 revenue exceed Wall Street estimates, reflecting robust investment in AI servers and computing capabilities. Shares of CoreWeave and Super Micro Computer jumped to their highest since June on Wednesday after upbeat forecasts from the two AI infrastructure companies signaled booming demand for computing capacity. Both companies have been beneficiaries of ⁠the insatiable demand ⁠for AI infrastructure, as data center operators build out the hardware needed for generative-AI workloads.

Server maker Super Micro's shares climbed more than 13%. Data center companies Applied Digital and IREN Ltd were also up 4% and 8%, respectively. Shares of Dell were 5% higher. CoreWeave is on track to add around $8 billion to its market value, while ⁠Super Micro could add more than $2 billion, if gains persist. More than seven brokerages raised their price targets on both CoreWeave and Super Micro stocks. CoreWeave raised its forecasts ⁠for annual revenue, adjusted operating profit and capital spending, as strong demand for its Nvidia-powered AI infrastructure enabled the company to secure better pricing on new contracts. Near-term capacity is effectively sold out, enabling CoreWeave to strike compute agreements on increasingly favorable terms, CEO Michael Intrator said. Its revenue backlog rose to $104.2 billion in the second quarter from $99.4 billion three months earlier, excluding over $25 billion in new commitments secured early this quarter. "Some investors may be spooked by the increased capex guidance, but the pricing environment would suggest that project returns are strengthening, even if unit costs are going up too," MoffettNathanson analysts said in a note. Tech companies have boosted their capital expenditure to feed the AI ⁠boom, piling on massive debt in the process, and in turn prompting a surge in hedging against the default risk of these heavily indebted 'hyperscalers'. Major U.S. financial institutions are also seeking to capitalize on the data center buildout. Bank of America pledged $250 billion for U.S. infrastructure financing by July 2027, days after a similar announcement from Morgan Stanley. Super Micro forecast 2027 revenue above Wall Street estimates, underscoring resilient customer investment in AI servers. The company's fourth-quarter gross margin of 17.5% exceeded both its preliminary estimate of 15%-17% and its initial forecast of 8.2%-8.4%.

S&P 500 Falls as Iran Risks Outweigh Renewed Optimism Over AI Stocks

David Morrison, senior market analyst at Trade Nation, questioned earlier assumptions that the conflict would end quickly. "I don't think anyone was pricing in the fact that this could still be going as we approach the end of the summer," he said. Technology shares traded slightly higher as investors reviewed fresh reports about Anthropic's financial outlook. Reuters reported that the AI company expects revenue of roughly $190 billion to in 2028. Moreover, Anthropic's second-quarter revenue reportedly surged above $11.5 billion. The figures supported demand expectations for processors, memory chips, data storage equipment and other infrastructure used to build AI systems. Meanwhile, Micron Technology shares rose about 4.5%, while Sandisk gained 6.7%. Nvidia added 0.2%, and Broadcom also moved higher. These advances helped the S&P 500 technology sector rise 0.1% and kept the NASDAQ near the flatline. Investors will watch Nvidia's quarterly report next week for more information about AI spending. Recent concerns have focused on how quickly companies can earn returns from their costly infrastructure projects. Strong earnings and revenue forecasts have reduced some of those concerns.

US Stock Market Rises as CoreWeave, Super Micro Shares Surge on AI Demand

Morgan Stanley Wealth Management strategist Ellen Zentner said, "In-line inflation will keep the 'no need to hike rates' narrative" intact. She added that another inflation report will arrive before the September meeting. Technology stocks supplied most of Wednesday's market gains. The S&P 500 information technology sector rose 1.2%, while the Philadelphia semiconductor index gained about 3%. Nvidia shares advanced 2%, Broadcom climbed 1.4%, and Micron Technology gained 4.4%. Dell Technologies and Cisco Systems also traded higher as investors returned to AI-linked companies. Additionally, jumped about 20% after reporting second-quarter results above market expectations. Revenue doubled from the prior year, while its adjusted operating margin reached 5%. The AI cloud provider also raised its annual capital spending forecast. CoreWeave expects 2026 capital expenditure between $35 billion and $39 billion. Super Micro Computer also gained as much as 17% after issuing an upbeat fiscal 2027 revenue forecast. Nebius rose about 15.5% after its cloud unit recorded a 514% increase in quarterly sales. IREN and Applied Digital gained 7.8% and 5.5%, respectively.

Wall St mixed as Middle East tensions eclipse tech strength

Aug 17 (Reuters) - The S&P 500 and the Dow inched lower on Monday as U.S.-Iran tensions dented sentiment, while some technology stocks rose after the report of a strong revenue forecast from AI lab Anthropic. Tehran will escalate tensions in the Strait of Hormuz and the wider region if diplomacy with the United States fails, a senior Iranian official told Reuters, pointing to an Iranian policy shift relying on offense rather than defense. Brent crude futures gained about 0.3%, with the S&P 500 energy index 0.2% higher. "(Investors) were telling themselves wars always come to an end. I don't think anyone was pricing in the fact that this could still be going as we approach the end of the summer," said David Morrison, senior market analyst at Trade Nation. Meanwhile, Reuters reported on Friday that Anthropic, which is preparing for its IPO, forecast 2028 revenue of roughly $190 billion to $200 billion, according to two people familiar with the company's financials. Chipmakers led gains among technology stocks. Western Digital and Sandisk rose 6.3% and 10%, respectively, making them the top performers on the benchmark index. Tech shares on the S&P 500 rose 0.6%, limiting losses elsewhere and boosting the tech-heavy Nasdaq. Markets will keep a close eye next week on results from chipmaker Nvidia, the world's most valuable company, for signs the tech-driven momentum can last. Nvidia's shares rose 1%. Danni Hewson, head of financial analysis at AJ Bell, said greater clarity on AI investments and the source of returns was allaying immediate fears of a "potential AI boom then bust". At 11:32 a.m. ET, the Dow Jones Industrial Average fell 198.47 points, or 0.37%, to 53,533.94, the S&P 500 lost 10.51 points, or 0.13%, to 7,775.25, and the Nasdaq Composite rose 32.38 points, or 0.12%, to 26,761.55. Declines in Microsoft and Sherwin-Williams weighed on the Dow. Concerns over the payoff from AI investments battered chip stocks recently, but robust quarterly results and forecasts signaling resilient demand have helped push the Nasdaq to within 1.5% of its all-time high. The S&P 500 closed at a record peak on Thursday after a batch of soft inflation data helped traders dial back the odds of an interest-rate hike by the U.S. Federal Reserve at its September meeting. Traders are pricing in a nearly 31% chance the Fed will raise rates by 25 basis points next month, sharply lower than the near-even chances of a hike versus a hold a week ago, according to CME's FedWatch tool. Still, Wells Fargo Investment Institute changed its Fed call and expects a 25-basis-point increase to rates this year, compared to no change anticipated earlier. Quarterly results from retail bellwether Walmart and home improvement retailer Home Depot, among the few names left to report in the current earnings season, will be watched this week. In other movers, U.S.-listed shares of Vista gained 5.1% after Peter Thiel bought a 1% stake in the Latin American oil company. Declining issues outnumbered advancers by a 1.67-to-1 ratio on the NYSE and by a 1.31-to-1 ratio on the Nasdaq. The S&P 500 posted 18 new 52-week highs and three new lows, while the Nasdaq Composite recorded 71 new highs and 85 new lows.

Nasdaq futures gain as tech stocks climb

Aug 17 (Reuters) - Nasdaq and S&P 500 futures rose on Monday, boosted as a strong revenue forecast from AI leader Anthropic supported technology stocks, while investors weighed the prospect of fewer interest-rate hikes against Middle East tensions. Reuters reported on Friday that Anthropic, which is preparing for its IPO, forecast 2028 revenue of roughly $190 billion to $200 billion, according to two people familiar with the company's financials. Most megacap and growth stocks were marginally higher in premarket trading. Amazon and Alphabet added 1.3% and 0.8%, respectively, helping Nasdaq futures. Chipmakers jumped, with shares of Micron Technology and Broadcom rising 3.5% and 1.2%, respectively. Tech stocks, particularly chipmakers, have come under pressure in recent months as investors grew concerned about the payoff from companies' heavy AI investments. A solid second-quarter earnings season also helped push the tech-heavy Nasdaq closer to record highs. Markets will keep a close eye on results from chipmaker Nvidia, the most valuable company in the world, next week for signs on whether the tech-driven momentum can last. Nvidia edged up 0.5% after a report said it has scaled back plans to support a proposed OpenAI data center project in Ohio, easing worries about circular financing in the sector. At 06:20 a.m. ET, Dow E-minis fell 72 points, or 0.13%, S&P 500 E-minis rose 10.75 points, or 0.14%, and Nasdaq 100 E-minis added 148 points, or 0.49%. Meanwhile, Iran called on the U.S. to accept defeat on Saturday, while President Donald Trump referred to Tehran as "very evil" and told Americans to prepare for continued high fuel prices as a result of the war. Progress towards peace talks and oil tanker traffic through the strategic Strait of Hormuz remained halted, with no sign the warring parties were moving toward ending the conflict. A batch of soft inflation data last week along with a surprise decline in retail sales helped traders dial back the odds of an interest-rate hike by the U.S. Federal Reserve at its September meeting. The lack of forward guidance from Fed Chair Kevin Warsh has meant greater scrutiny of economic data as markets try to guess the central bank's policy path, while elevated oil prices from the Iran conflict stoke inflation fears. Traders are pricing in a nearly 31% chance the Fed will hike rates by 25 basis points next month, sharply lower than the near even chances of a hike versus a hold a week ago, according to CME's FedWatch tool. Reduced expectations of an imminent rate raise and robust earnings last week saw the benchmark S&P 500 cruise to a fresh record close on Thursday. Markets will turn to a new round of quarterly results later this week, with retail bellwether Walmart, home improvement retailer Home Depot and chipmaker Analog Devices among the few names left to report in the current earnings season. So far, 453 companies in the S&P 500 have reported earnings, with 84.8% beating analysts' estimates, according to LSEG IBES data. In other movers, U.S.-listed shares of Argentina's Vista gained 7.1% after Peter Thiel bought a 1% stake in the oil company. (Reporting by Avinash P in Bengaluru; Editing by Pooja Desai)

Strong AI earnings lift S&P 500, Nasdaq as inflation data calms rate-hike jitters

Aug 12 (Reuters) - The S&P 500 and the Nasdaq rose on Wednesday as upbeat earnings from AI infrastructure firms boosted technology stocks, while largely in-line inflation data reinforced bets the U.S. Federal Reserve will hold interest rates steady in September. The S&P 500 information technology sector jumped 1.2%, leading sector gains on the benchmark index as investors bet on AI-fueled demand sustaining momentum. CoreWeave surged 19% after the AI cloud company lifted its annual capital spending forecast and topped second-quarter earnings estimates. Other AI infrastructure providers also rose, including data-center operators IREN and Applied Digital, which gained 7% and 3.4%, respectively. Neocloud company Nebius Group jumped 25%, helped by second-quarter results. Super Micro Computer topped the S&P 500 with a 15% climb after the AI-server maker forecast fiscal 2027 revenue above Wall Street expectations. Chipmakers gained, with Nvidia rising 2.6% and Micron Technology adding 6.4%. The broader semiconductor index advanced about 3.1% and was on track for its biggest one-day jump in more than a week. "(AI trades) have more to run for good reason. There's tremendous funding ahead and revenue scale for many... there's further legs ahead. The demand for compute is at record highs," said Eric Schiffer, chairman of The Patriarch Organization, a Los Angeles-based family office. "You're going to see continued signs and signals and deals and funding related to AI and AI has been powering this market."

Wall Street's fear gauge, the CBOE Volatility Index, briefly touched a seven-month low and was last down 0.49 points at 14.79. Investors also assessed U.S. consumer prices data, which increased slightly in July, weakening the argument for the central bank to hike interest rates next month. Traders are now pricing in a 62% chance of the Fed holding rates at its September meeting, according to CME's FedWatch Tool. Before the data was released, they were split between a hike and no change. Economic data, especially inflation figures, have drawn increased scrutiny as elevated energy prices due to the Middle East conflict raised rate-hike bets and Fed Chair Kevin Warsh stayed firm on muted forward guidance. The situation in the Middle East remained volatile as a senior Iranian source said there had been no progress in talks to revive the interim deal agreed in June and define a timeframe to implement it, while shipping attacks continued.
