Wall Street drifted through mixed trading on June 10 as technology stocks kept swinging through one of their choppiest stretches of the year. The S&P 500 was virtually flat after recovering from an early loss of 0.8%, leaving the index close to avoiding its first back-to-back decline in three weeks. The Dow Jones Industrial Average sat 268 points lower, or 0.5%, at 10:30 a.m. Eastern time, and the Nasdaq composite was down 0.1%.
The action is concentrated in the AI trade, where some of the year’s biggest winners are now showing the most stress. Super Micro Computer, which sells AI servers, tumbled 14.1% on word late Tuesday that it plans to raise $7 billion in cash by selling common stock and convertible preferred stock. The broader market has been shaky since last week, when AI-driven names ran to records and then reversed. Among the worries on the buy side: their prices may have simply shot too high, too fast.
Super Micro’s $7 Billion Raise Tests the AI Trade
Super Micro Computer’s plan to raise $7 billion landed with a thud on Wednesday, dragging the server maker’s shares down 14.1% and dragging the AI server trade down with it. The company said late Tuesday it would sell common stock and convertible preferred stock to fund purchases of components and chase a multi-billion dollar order backlog. Such raises pull in the most cash for a company when its share price is high, and they dilute the ownership stakes of existing shareholders.
Super Micro has become a closely watched proxy for how fast the AI build-out is moving. The four largest cloud platforms have leaned into building out AI training capacity, and the company has been one of the public vehicles for that demand. The decision to issue equity and convertible preferred suggests the cash needed to chase the backlog has outrun what the company can fund from operations alone. The 14.1% slide is the market’s read on that gap, and it landed the same morning other AI hardware names were swinging in the opposite direction.
Other AI stocks are not waiting around to react. Micron Technology spent the morning swinging from an early loss of nearly 4% to a gain of 1.1%, on top of a week that has already erased and rebuilt a sizable chunk of its 2026 gain. The volatility, not the direction, is the story.
Micron’s Whipsaw Week Puts the AI Trade on Notice
Micron Technology’s stock is up 231.2% for the year so far, a run that has carried the memory chip maker into the center of the AI trade. The same momentum is now driving some of the most violent trading days the stock has seen in months. The stock sank 7.7% on Thursday, plunged 13.3% on Friday, and then rallied 9.9% on Monday. By Wednesday morning it had swung from an early loss of nearly 4% to a gain of 1.1%, all inside a five-session window. The five-day stretch puts a number on how loosely the AI trade is being held. Stocks that doubled or tripled on AI demand are now testing whether that demand can be financed, built, and booked fast enough to keep valuations aloft. Micron’s memory chips are a critical input for AI training, and the swings trace directly to its role in the supply chain. The wider AI trade, from servers to networking, looks like Micron’s tape in miniature, and tech stocks facing an early 2026 selloff are now testing whether AI demand keeps up with the price tag.
Some names inside the AI stack were firmer on Wednesday. Shares of KLA rose 5.9% and Applied Materials added 6%, and both were among the strongest forces pushing the S&P 500 higher. The split shows a market still willing to fund parts of the AI build-out while questioning the price tag on others.
- Super Micro Computer: -14.1% Wednesday on $7B raise
- Micron Thursday: -7.7%
- Micron Friday: -13.3%
- Micron Monday: +9.9%
- Micron year-to-date: +231.2%
- KLA Wednesday: +5.9%
- Applied Materials Wednesday: +6%
Inflation Arrived Hot, Just Not Hotter Than Expected
The morning’s other major event landed before the opening bell. The May consumer price index rose 0.5% from April and 4.2% from a year earlier, the highest annual pace in three years, according to the May 2026 consumer price index release. The Bureau of Labor Statistics reported the figures at 8:30 a.m. Eastern time, and the bond market had been bracing for the worst.
The reason it did not get worse: economists had already penciled in much of the damage. The headline matched forecasts almost exactly, and the underlying gauge that strips out food and energy was tamer from April through May than analysts had expected. The energy index carried most of the heat, climbing 3.9% on the month and 23.5% over the prior year, with gasoline up 7.0% on the month and 40.5% year-on-year. The core measure rose just 0.2% in May and 2.9% over the prior year, leaving the door open for the Federal Reserve to hold its nerve on rates.
Bond yields eased in response, taking some of the pressure off stocks. The 10-year Treasury yield dropped to 4.52% from nearly 4.55% earlier in the morning, and the two-year yield, which tracks Fed expectations most closely, edged down to 4.11% from 4.13%.
High bond yields slow economies and undercut the most expensive investments first. The most expensive investments on the tape right now sit inside the AI trade, and some critics are calling AI a bubble where investment inflated too far. The inflation print gave the bond market a small reason to take some of that pressure off, which is part of why the S&P 500 was holding flat by mid-morning rather than sliding.

The Fed Hike Bet Slips a Notch
Markets had been leaning toward the view that the Federal Reserve will have to raise rates at least once this year, with inflation refusing to cool and the U.S. job market still strong. The CME FedWatch tool places the odds of a 2026 hike near a 50% chance. Wednesday’s inflation update trimmed that view by a small amount, with traders pulling back a smidgen on the odds of a move, according to data from CME Group. Several Wall Street desks, including on the prediction market Kalshi, had built the same bet over the prior week, with the implied probability of a 2026 hike climbing sharply after a stronger-than-expected payrolls print.
I think there actually could be one this year, and for good reason. Inflation is pretty sticky.
Roger Ferguson, the former Federal Reserve vice chairman, said on CNBC earlier this month that the case for a move is real, as odds of a 2026 Fed rate hike climbing on prediction markets. The case for holding is real too. Goldman Sachs Asset Management’s Lindsay Rosner put the counter-case plainly in a note to clients. The Fed’s job market is no longer the worry, she wrote, and the next move depends on the duration of the war with Iran. For now, the move is to not move.
Overseas, the Tech Selloff Carries Its Own Weight
Wall Street is not the only tape under pressure. South Korea’s Kospi tumbled 4.5% on Wednesday, dragged by losses at tech giants Samsung Electronics and SK Hynix. Tokyo’s Nikkei 225 sank 1.9% after a fresh inflation jolt of its own, with oil prices pushed toward $100 on Iran conflict keeping energy costs elevated for Japanese importers. Producer prices in Japan rose 6.3% in May from a year earlier, the fastest pace since March 2023, according to Bank of Japan data tracked by Trading Economics. The reading beat forecasts of 5.5% and was driven heavily by surging energy and commodity import costs.
SoftBank Group, the Japanese technology and telecommunications giant with a strong AI focus, lost 8.3% on the session. The slide tracks the same pattern playing out in U.S. AI names. When global capital questions the price tag on the AI build-out, the most exposed names move the most.
- Kospi: -4.5%, dragged by Samsung Electronics and SK Hynix
- Nikkei 225: -1.9%
- SoftBank Group: -8.3%
- Japan May producer prices: +6.3% year-on-year, fastest since March 2023
- Brent crude: $92.60, +1.3% on the session
Two Tugs on the Tape at Once
Two forces are pulling Wall Street in opposite directions on June 10. The AI trade is showing real stress, from a 14.1% slide in a server maker raising new equity to an 8.3% drop in a Japanese conglomerate with a heavy AI focus. Inflation came in hot, but the underlying gauge was softer than expected, and the bond market took that as a small reason to ease.
Brent crude oil rose 1.3% to $92.60 after President Donald Trump warned Iran would “pay the price” for stalled negotiations over the Strait of Hormuz, adding a fresh input to the inflation picture. Higher oil prices feed the energy component of the CPI, and the energy component is what carried the headline print higher this month.
The market is, for now, holding the line. The next test for the bond market’s relief is the CPI print that follows this one. The next test for the AI trade is whether the cash raised this week by names like Super Micro is enough to keep building, and whether the demand at the other end of those orders keeps up with the cost of financing it.
