May 7, 2026 Market Wrap

The day’s dominant story was the market’s continued push into artificial intelligence infrastructure, with multiple headlines pointing to another round of spending, partnerships and demand signals across the supply chain. Nvidia sat at the center of that narrative. The company was tied to a $2 billion investment in Nebius, which has lifted Nebius stock 57% since the deal, and later to talks with SoftBank and Foxconn to build Japanese AI servers, plus a $500 million backing of Corning for fiber optics as Jensen Huang warned about copper’s limits in AI factories. That same theme showed up in earnings and guidance from suppliers and adjacent names: WESCO International raised 2026 guidance on data center demand and jumped 19.0%, Coherent beat Q3 with $1.806 billion in revenue and $1.41 in EPS and rose 20%, and AAON surged more than 50% to all-time highs after blowout earnings tied to data center demand. Micron also remained a standout, with shares up 108% year to date and 715% over the past year on what was described as an AI memory supercycle. Even the broader tape reflected that strength, as the S&P 500 reached record highs in a stealth rally led by technology, while the Nasdaq gained 0.50% and the S&P 500 added 0.07% at the 11:00 ET update. Alphabet and OpenAI-related headlines added a second layer to the AI story, but with more caution around regulation, competition and the pace of build-out. A headline on Musk’s trial against OpenAI raised AI risk questions for GOOGL, while another said Alphabet shares rose after robust earnings but urged caution on underlying quality. Anthropic also added to the demand picture, saying Q1 2026 revenue and usage surged 80-fold and that demand for Claude products was outpacing capacity. That combination of strong usage growth and legal or regulatory overhangs helped frame the day’s AI discussion as more than just a straight-line rally. It was also notable that the market kept separating winners by exposure: Nvidia-linked names and data center suppliers were bid, while headlines about helium supply disruptions from the Iran conflict reminded traders that chipmaking and AI build-outs still face physical bottlenecks. In the same vein, FPT was named a Microsoft Frontier Partner in Southeast Asia, extending Microsoft’s enterprise system integrator network and reinforcing the breadth of the AI ecosystem beyond the largest U.S. platforms. Outside AI, several single-stock moves stood out. Amazon was in focus twice: first on a report that Amazon Pharmacy will stock Novo Nordisk’s Ozempic pill at U.S. kiosks and offer same-day delivery, and earlier on a GXO Logistics plunge that analysts viewed as overdone in relation to AMZN-linked logistics exposure. Berkshire also drew attention after Greg Abel sold Bank of America for a seventh consecutive quarter, signaling continued reduction in the BAC position. In consumer and healthcare, Planet Fitness fell more than 30% after Q1 results and a cut to FY26 guidance below estimates, while Gilead was expected to report higher Q1 earnings and analysts revised forecasts ahead of the call. Other names moved on company-specific updates: Kontoor Brands rose after Q1 sales increased 29.7% year over year to $808 million, Castle Biosciences outlined 2026 revenue of $345 million to $355 million as TissueCypher volumes grew 58%, ACI Worldwide lifted its 2026 revenue and adjusted EBITDA outlook, and Collegium guided to $805 million to $825 million in 2026 product revenue while planning to close a $650 million AZSTARYS deal in the second quarter. Sadot Group, by contrast, received a Nasdaq compliance notice on shareholder equity and slid nearly 25% after hours. The rest of the session showed a market still willing to reward strength in select growth and industrial names while punishing misses and balance-sheet issues. Tesla rose after China sales jumped 36% in April, a sign of export strength, and the stock also appeared in headlines tied to the Musk-OpenAI courtroom drama and broader billionaire-tax debate. Crypto sentiment was mixed but firm enough for XRP bettors to show the strongest conviction for a return to $1.60 in May. In the background, long-term mortgage rates bounced back to four-week highs, lifting homebuying costs again and adding a rate-sensitive headwind outside the tech complex. Looking ahead, the key things to watch are whether the AI infrastructure trade keeps broadening beyond Nvidia into suppliers like Corning, WESCO, Coherent and AAON, whether Alphabet and OpenAI-related legal and regulatory headlines continue to shape sentiment, and whether the day’s record-high index levels can hold if rates, supply constraints or weak earnings from consumer names start to matter more.
