Market Recap: Tuesday, April 28 — Stocks Slip as OpenAI Revenue Report Rattles AI and Chip Names
Stocks pulled back Tuesday after a report questioned OpenAI's revenue and user growth, dragging chipmakers and AI-linked names lower. The Dow held nearly flat.
Market Overview
Stocks pulled back Tuesday after a Wall Street Journal report questioned whether OpenAI is hitting its internal revenue and user targets — a story that put pressure on chipmakers and other companies tied to the AI buildout. OpenAI denied the claims, but the headline was enough to rattle a market that has rallied for weeks on AI spending optimism. The Dow held up much better than the Nasdaq, helped by gains in energy and consumer staples.
Index Performance
| Index | Close | Change |
|---|---|---|
| S&P 500 (SPY) | $711.68 | -0.49% |
| NASDAQ (QQQ) | $657.59 | -1.01% |
| Dow Jones (DIA) | $491.42 | -0.08% |
The split tells you most of the day's story. The tech-heavy Nasdaq took the brunt of the selling, while the Dow — which has less semiconductor and big-tech exposure — barely budged. That's a classic sign of rotation rather than broad weakness: investors trimmed AI winners and parked money in steadier corners of the market.
What Drove the Market Today
The trigger was a Wall Street Journal report claiming OpenAI is missing internal goals for both revenue and new users. OpenAI pushed back on the report, but for investors the question was simple: if the most-watched AI company is growing slower than hoped, will hyperscalers keep spending so aggressively on AI data centers and chips? That doubt rippled through the chip sector and AI-adjacent names like Oracle and CoreWeave.
Layered on top: ongoing U.S.–China tension over AI technology and lingering concerns about global supply chains, both of which add friction for chipmakers. Energy stocks went the other way as oil prices climbed, giving the Dow some support and helping consumer staples names like Coca-Cola, which posted solid quarterly numbers.
Earnings season also kept things busy. Strong reports from staffing, healthcare-tech, and pharma companies lifted individual stocks even as the broad indices slipped — a reminder that on most days, company-specific news matters more than the headline number.
Today's Top Movers
Gainers
- KFRC (Kforce) jumped roughly 43% to $45.87 after the staffing firm posted Q1 revenue of $330 million — its first year-over-year revenue growth since late 2022 — and issued upbeat Q2 guidance.
- CRY rose about 40% to $24.96 alongside corporate news in the medical-device space.
- KNSA (Kiniksa Pharmaceuticals) climbed about 23% to $53.85 after raising 2026 guidance for its lead drug Arcalyst, with multiple analysts hiking price targets.
- OMCL (Omnicell) gained about 21% to $45.51 after a Q1 beat driven by its Titan XT product line, with non-GAAP EPS more than doubling year-over-year.
- WLACU rose 77% to $28.38 on a day without a clear, widely-reported catalyst we could verify in major financial press.
Losers
- NVTX fell about 35% to $53.02 and CRMX dropped about 36% to $21.47 — both small-cap moves without prominent coverage today.
- CSEX lost about 29% to $20.74, also without a widely-reported catalyst.
- RMBS (Rambus) dropped about 21% to $111.27 after Q1 earnings. Revenue and EPS were actually solid, but analysts at Baird downgraded the stock to Neutral, arguing Rambus is less positioned than memory makers to benefit from a looming memory-chip shortage because its business depends more on chip units sold than on prices charged.
- RIOX slipped roughly 19% to $25.04 in a quiet news day for the name.
Most Active Stocks
Volume leaders were dominated by the chip story. SOXS, a leveraged ETF that moves opposite the semiconductor sector, traded over 236 million shares as some investors hedged or positioned against the group. NVDA finished down about 2% to $213.15 on heavy volume, caught in the same OpenAI-driven move. INTC and NOK also saw outsized turnover, tied to broader chip-sector and telecom-equipment flows.
What This Means for You
Days like today are a useful reminder that markets don't only move on numbers — they move on stories. A single report about one private company's growth was enough to push hundreds of billions of dollars in market value lower, even though OpenAI isn't publicly traded. When a single theme like AI dominates returns, even indirect news can move the entire group. That's not unusual — it's how concentrated rallies work in both directions.
