Stock Market Today: May 28, 2026 — Records Hold as PCE Inflation Spikes
The S&P 500 and Nasdaq closed at fresh record highs on May 28, 2026, with the S&P up 0.58% to 7,563.63 as a 36% surge in Snowflake powered AI-software gains — even after April PCE inflation jumped to 3.8%, its hottest in nearly three years.
What Moved the Stock Market May 28, 2026
US stocks pushed to new records despite the hottest inflation print in nearly three years, as an AI-software rally outweighed a sharp PCE acceleration. The SPY-tracked S&P 500 rose 43.27 points, or 0.58%, to a record close of 7,563.63. The Nasdaq Composite added roughly 242 points, or 0.91%, to a record 26,917.47, led by software and infrastructure names. The Dow Jones Industrial Average lagged, gaining about 25 points, or 0.05%, to 50,668.97, while the small-cap Russell 2000 finished essentially flat — up 0.76 points, or 0.03%, to 2,921.30. The dominant theme: inflation data spooked no one, and the AI trade did the heavy lifting again.
VIX, Yields & Commodities on May 28, 2026
The CBOE Volatility Index (VIX) edged lower to 16.29, a risk-on reading consistent with back-to-back record closes. The 10-year Treasury yield rose about 2 basis points to 4.50% as traders priced the firm PCE print against a Fed now widely expected to hold rates through year-end. The US dollar index held near recent levels.
Commodities whipsawed on Iran headlines. WTI crude (CL=F) pared an early geopolitical spike and slipped back below $90 a barrel — roughly a six-week low — after Washington and Tehran reportedly agreed to a 60-day memorandum to extend their ceasefire and gradually restore Persian Gulf energy exports. Gold (GC=F) fell below $4,400 an ounce to a two-month low, as the easing of supply fears outweighed reports of fresh US strikes on an Iranian military site.

May 28, 2026 Biggest Stock Movers
SNOW (Snowflake) +36% — The data-cloud company posted its best day ever after beating Q1 estimates, raising its full-year outlook, and announcing a five-year, $6 billion commitment to Amazon Web Services. The print reignited enthusiasm for the AI-infrastructure trade and set the tone for the whole tape.
KSS (Kohl's) +15% — The department-store retailer surged after reporting its strongest comparable-sales performance in four years, a rare bright spot in beaten-down brick-and-mortar retail and a sharp short-squeeze candidate on the move.
PLAB (Photronics) -25% — The photomask maker plunged after fiscal-Q2 revenue fell, hit in part by an ongoing supply crunch in memory chips, and management trimmed its outlook. It was the day's worst single-stock decline among mid-caps.
MSFT (Microsoft) +3.4% — Shares climbed on analyst optimism and reports the company is building more in-house AI models, helping offset weakness elsewhere in mega-cap tech. ORCL and PLTR rode the same AI-software wave, each up 3% to 4%.
NVDA (Nvidia) -1% — Chipmakers pulled back even as software soared, with Nvidia slipping on lingering valuation and AI-capex-durability concerns. CRM (Salesforce) also fell roughly 1% as a softer current-quarter revenue outlook overshadowed an otherwise solid quarter.
Macro & Policy: May 28, 2026
The headline event was the April PCE report. Headline PCE rose to 3.8% year-over-year — the highest in nearly three years — up from 3.5% in March, while core PCE climbed to 3.3%, the hottest since November 2023. Markets shrugged: with the Fed already expected to stay on hold through year-end, equities treated the print as priced-in rather than a fresh rate threat. Geopolitics drove the intraday chop, as a debunked US-Iran peace report and conflicting strike headlines whipsawed oil and gold before the reported 60-day ceasefire memorandum stabilized energy markets into the close.
Earnings Highlights: May 28, 2026
Snowflake (SNOW) topped Q1 estimates and raised full-year guidance, with the marquee $6 billion AWS deal underpinning the 36% pop. Kohl's (KSS) delivered its best comparable-sales quarter in four years, driving a double-digit rally. Photronics (PLAB) disappointed: fiscal-Q2 revenue declined on the memory-chip supply crunch, and softer guidance sent shares down more than 25%.
