May 15, 2026 Market Wrap

May 15 was defined by a sharp split between AI-linked winners and a broader tech selloff tied to Washington and Beijing. The day began with a wave of company-specific earnings and deal headlines, but the dominant market story quickly became the Trump-Xi summit and its fallout. By the 8:00 ET bulletin, the summit had already triggered a tech selloff, with Nasdaq-100 futures down more than 1% and Treasury yields topping 4.5%. That pressure carried into the afternoon: Intel fell 7% as rate-hike fears hit the Nasdaq 100, Broadcom slipped nearly 3% after the summit ended without a chip deal, Micron gave back some of its recent surge, and Coinbase slid 6% as Thursday’s regulatory-optimism rally unwound. Even so, the tape was not uniformly weak. Microsoft stood out as a relative strength name, rising 4% to $424.65 while the Nasdaq slid, after Pershing Square disclosed a new stake and Bill Ackman called it a core holding, citing $200 billion of value for Microsoft’s 27% OpenAI stake. Applied Materials also bucked the risk-off tone, reporting record revenue and earnings in Q2, with record revenue and its highest gross margin in more than 25 years. AI remained the day’s central sector theme, but the headlines showed a market trying to separate long-term winners from near-term volatility. Earlier in the morning, Citi lifted AMD’s price target by $110 to $358 while keeping a Neutral rating, and another note argued that AMD and Broadcom could be smarter AI supercycle plays than Nvidia right now. Nvidia itself stayed in focus throughout the day: one headline said it could deliver another blowout earnings report on May 20 without moving the stock much, while another tied Jensen Huang’s warning that AI may soon need 1,000 times more energy to Elon Musk’s comment that “space is the only way.” Later, a separate piece framed Xanadu’s CEO as defending a long-term vision after a stock plunge, underscoring how quickly sentiment can turn in AI-related names. The day also brought a major funding headline for the broader AI ecosystem, with Anthropic and the Gates Foundation committing $200 million to AI for healthcare and education as Anthropic moved closer to a $30 billion fundraising round at triple its prior valuation. Microsoft appeared in that same orbit as well, with headlines about its East Africa data center project stalling after Kenya talks broke down, even as the stock drew fresh support from Pershing Square and Ackman. Outside the megacap tech complex, several individual names posted sharp moves on company-specific news. Comfort Systems USA completed a long-running buyback and beat Q1 expectations, with the stock up 5.2% on AI data center demand. P3 Health Partners reported a narrower-than-expected Q1 loss and surged 42.68% after hours. Honda posted its first annual operating loss in nearly 70 years, yet shares rose more than 7%, while Alliance Entertainment reported 21% net revenue growth in Q3 2026 on music and collectibles gains despite a slight gross margin dip. On the media and internet side, UK regulators cleared the $3.7 billion Getty-Shutterstock merger, though Shutterstock must divest its UK editorial business. Rumble slipped further into the red and warned about inaccurate monthly active user data during its Google transition, while CrowdStrike hit a new all-time high as analyst optimism outweighed the cautious market tone. Bright Mountain Media also reported a small GAAP loss and $14 million in revenue. Crypto and digital-asset names were mixed but active. Bitcoin held near $80,000 after the Clarity Act boosted institutional sentiment, and Bitcoin ETFs saw $131.3 million in net inflows, but Strategy also announced a $1.5 billion note repurchase tied to its convertible debt. Coinbase, however, gave back part of its prior day’s move and fell 6% intraday to around $199. A separate headline said Samson Mow projected Michael Saylor could overtake Elon Musk in wealth if Bitcoin reaches a specific level, while another analyst called Bitcoin’s top at $125,000 and then turned bearish for the summer. In autos, Honda’s loss contrasted with a headline about Tesla and Toyota exposing a surprising industry truth, and GM was framed as looking to take advantage of rare Ford weakness. By the close, the main thing to watch tomorrow is whether the summit-driven tech weakness extends into the next session or whether earnings and stock-specific catalysts continue to override macro pressure. Nvidia’s May 20 earnings date, ongoing Microsoft-related headlines, and the next move in Bitcoin near $80,000 are likely to keep attention centered on the same high-profile names that dominated today.
