Tech Sell-Off Shakes Markets; SpaceX Loses One-Third
A broad sell-off in technology stocks on June 23, 2026 pushed major indices lower as investors reacted to rising rate expectations and concerns about increased corporate spending on AI. European and US futures fell — the DAX slid about 400 points intraday and Nasdaq 100 futures fell up to 3%. Chipmakers and semiconductor-equipment firms were especially weak ahead of several earnings reports this week; Micron is due to report, and Qualcomm is holding an investor event. SpaceX’s market value dropped from a near‑record high of almost $3.0 trillion on June 16 to about $2.03 trillion, a decline of roughly one-third since the peak. Market participants cited expectations that the Fed under new chair Kevin Warsh may raise rates, higher energy costs and tariffs, and the sustainability of debt-funded AI investments as drivers of the sell-off.
Broad tech-sector sell-offs shift market valuations and increase near-term uncertainty for technology companies — particularly chipmakers whose upcoming earnings will influence sector direction — but this is a market movement rather than a platform policy or major structural change.

Global Tech Sell-Off Intensifies
Global equity markets experienced a sharp sell-off led by technology and semiconductor stocks on June 23, 2026. South Korea’s Kospi plunged about 10%, driven by drops exceeding 12% in SK Hynix and Samsung. European benchmarks fell, with the Stoxx 600 down roughly 1% and its Technology index off about 3%. U.S. Nasdaq 100 futures fell ~2.7% and semiconductor names and ETFs posted steep losses (SOXX down ~6.2%; Intel, Micron, AMD and Nvidia all lower). SpaceX shares extended earlier declines. Market commentators including Wedbush’s Dan Ives framed the sell-off as a potential buying opportunity, while Tom Hulick of Strategy Asset Managers said liquidity and earnings momentum reduce the risk of a market catastrophe. Micron’s upcoming earnings were cited as a near-term catalyst.
Dax Falls as Tech Rally Appears to Fade
European and US stock markets slid at the end of the week as renewed weakness in the technology sector weighed on benchmarks. The Dax closed down 1.3% at 24,671, marking a monthly decline for June, while the Nasdaq 100 showed roughly a 4–5% weekly loss. Semiconductor and AI‑linked chip names led the selloff after traders took profits following recent gains; Micron’s prior results-driven rebound was described as fleeting. Corporate headlines included a manager magazin report that Volkswagen may cut up to 100,000 jobs. Commodity markets saw oil prices fall after Saudi Aramco resumed shipments from Ras Tanura and reports of greater tanker movements, leaving Brent around $73.70 and WTI near $70.34 per barrel. Analysts cited concerns about chip demand sustainability amid product price increases at major device makers.
AI's Black Friday: Major Tech Market Sell-off
Gary Marcus's Substack essay reports a sharp, AI-driven market sell-off on June 5–6, 2026 that erased roughly half a trillion dollars of market value and hit chip, cloud compute and major tech names hard. Semiconductor and GPU-leasing firms (NVidia, Broadcom, Micron, CoreWeave, Nebius) and large tech platforms (Oracle, Microsoft, Meta, Google) fell along with South Korea’s KOSPI (notably Samsung Electronics and SK Hynix). The piece highlights reports that the Trump administration discussed taking an equity stake in OpenAI, and cites filings and tweets saying SpaceX is leasing large GPU capacity to Google and Anthropic (including a reported $920M/month cloud agreement). Marcus argues these developments point to overcapacity, bailout-like capital flows, geopolitical trust risks if government stakes occur, and limited real-world AI productivity so far.
