How a Single Earnings Report and a Jobs Surprise Ended Wall Street’s AI Rally

The market reaction was swift and brutal. Broadcom shares plunged between 12% and 15% in a single session, erasing between $280 billion and $350 billion in market value, depending on the intraday trough . The selling immediately radiated through the semiconductor complex. Micron Technology fell 6.6% to 7%, Advanced Micro Devices dropped 6.3%, and the PHLX Semiconductor ETF (SOXX) ended the day 2.1% lower, pulling down other AI-exposed names like ARM and Nvidia in sympathy . As one analyst noted, Broadcom's guidance had become a bellwether for the entire AI infrastructure trade, and the failure to raise the bar was treated as a sector-wide warning .

The Macroeconomic Amplifier: A Jobs Report That Killed Rate-Cut Hopes

If Broadcom lit the fuse, the U.S. Bureau of Labor Statistics detonated the charge the following morning. On Friday, June 5, the May employment report showed that the U.S. economy added 172,000 nonfarm payroll jobs—more than double the consensus economist estimate of roughly 85,000 . The unemployment rate held steady at 4.3%, and average hourly earnings rose 0.3% month-over-month, with the annual wage gain at 3.4% .

The data painted a picture of a labor market that was far from cooling, immediately resetting expectations for Federal Reserve policy. Markets rapidly repriced the odds of further interest rate cuts to near zero and instead began pricing in a higher probability of a rate hike. Money markets moved to see a 98% chance that the Fed would increase rates by 25 basis points before the end of the year . The shift was particularly potent because it came as Kevin Warsh prepared to take over as Fed Chairman, with the strong data giving hawks on the committee fresh ammunition .

For technology and growth stocks, which are highly sensitive to interest rate expectations, the effect was devastating. The S&P 500's historic nine-week winning streak snapped, and the tech-heavy Nasdaq suffered its largest daily decline since 2025 . The 2-year Treasury yield jumped roughly 10 basis points as bond markets sold off in tandem . The one-two punch of a valuation-driven chip selloff and a macro-driven rate repricing created a perfect storm, with Nvidia falling 6.2%, Broadcom sliding a further 7.9%, and Micron plunging 13.3% in the Friday session alone .

The Shockwaves: How the Selloff Raced Across Global Markets

The U.S. rout did not stay contained. As trading desks opened across Asia, the selling pressure cascaded through markets most exposed to the AI and semiconductor supply chain.

Asia-Pacific bore the heaviest brunt. MSCI's broad regional equity gauge dropped 2.25% . South Korea, seen as one of the purest plays on the AI trade through its memory-chip giants, suffered the most dramatic losses. The Kospi index plunged 5% to 5.5%, with an intraday swoon that briefly approached 7% . SK Hynix, a critical supplier of high-bandwidth memory for AI accelerators, tumbled 7.6%, while Samsung Electronics shed 4.3% . Japan's Nikkei 225 closed 1.3% to 1.5% lower, Australia's S&P/ASX 200 slipped 0.6%, and Hong Kong's Hang Seng fell 0.8% .

European markets opened lower in sympathy, with semiconductor stocks sliding in line with the global risk-off mood. The Stoxx Europe 600 technology sector was under pressure, though Europe's relatively lighter weighting in AI chip names and steadier energy prices helped the broader market recover some ground by midday .

U.S. Futures pointed to continued pain before the cash market even opened. Nasdaq 100 futures fell 0.9% to 1.2% in premarket trade, while S&P 500 futures dropped roughly 0.4% to 0.7%. Nvidia, AMD, Intel, Micron, and Broadcom all registered premarket declines as investors braced for the payrolls data that would ultimately confirm their worst fears .

The S&P Index Block: SpaceX Denied a Fast Track

Occurring simultaneously with the selloff but driven by an entirely separate set of rules, S&P Dow Jones Indices delivered a decision on June 4 that reshaped expectations for the year's most significant IPO. After months of consultation, the committee announced it would not create a fast-track entry path for megacap IPOs into the S&P 500, diverging from rival index providers Nasdaq and FTSE Russell, which had already loosened their own criteria .

The decision directly impacts SpaceX, Elon Musk’s privately held rocket and satellite company, which was preparing for a blockbuster IPO valued at approximately $1.75 trillion . It also affects the planned public debuts of AI companies Anthropic and OpenAI. Under the existing rules, which S&P decided to maintain, a company must meet three core requirements: four consecutive quarters of positive GAAP earnings, a minimum 12-month exchange listing, and a sufficient free-float of publicly traded shares .

SpaceX fails on nearly every front. The company posted a net loss of $4.94 billion in 2025 on $18.67 billion in revenue . Only approximately 5% of its shares are expected to be floated in the initial offering, far below the threshold needed for a standard free-float adjustment . S&P's statement was unambiguous: "Exceptions to the requirements for financial viability, minimum listing duration, and investable weight factor should not be granted solely based on market capitalization" .

The practical consequence is significant. By denying fast-track entry, S&P has cut off SpaceX and its peers from immediate access to the trillions of dollars in passive capital that track the S&P 500. Underwriters will now have to market the IPO without the inclusion premium that index membership typically confers, potentially affecting initial demand and valuation . For the broader market, the decision reinforced a theme of the week: the rules are not bending for technology's biggest names, whether in the semiconductor earnings game or the index-inclusion contest.
