Weekly Markets Roundup: AI Chip Selloff Caps a Losing Week

The week in markets: June 21 to June 27, 2026. It was a week of widening fractures. The artificial-intelligence trade that has powered Wall Street for two years cracked open, dragging the Nasdaq to its fifth straight losing session and a sharply negative week, even as a record-shattering earnings report from memory maker Micron proved the boom is far from over for the corners of the chip world with real pricing power. Crypto suffered its own reckoning, with bitcoin sliding to its lowest level since September 2024 and Binance preparing to switch off its services across the European Union. Money rotated, leadership narrowed, and a more hawkish Federal Reserve loomed over all of it. Here are the biggest stories of the week and what they mean heading into the new month.

Top Stock Stories of the Week

AI and Semiconductor Selloff Caps a Losing Week

The dominant story was a brutal repricing of the AI hardware trade. Investors spent the week questioning whether the industry's debt-funded spending spree on data centers will ever earn its keep, and the selling was savage. By Friday's close the Nasdaq Composite had fallen roughly 4.6 percent on the week and logged its fifth consecutive losing session at 25,297.62, while the S&P 500 shed close to 2 percent to 7,354.02 and the Dow Jones Industrial Average held up best, barely changed, as money rotated into value, per CNBC. The damage was concentrated in chips: across the June rout roughly 1.4 trillion dollars in market value was erased from the AI semiconductor complex, with Nvidia alone shedding about 279 billion dollars, and on the worst single session the Philadelphia Semiconductor Index dropped near 10 percent as Broadcom fell about 12.6 percent and Marvell sank around 17 percent. A New York Times report that OpenAI may delay its public listing into next year added fuel, since a postponed mega-IPO reads as a vote of caution on AI's near-term returns. We tracked the rout day by day, from the June 24 semiconductor sell-off through Friday's evening review.

Micron's Blowout Quarter and the $100 Billion Memory Supercycle

The week's counterpoint came from Micron Technology, which after the bell on June 24 delivered one of the most striking earnings reports in the chip industry's history. The company posted record quarterly revenue of about 41.46 billion dollars, up roughly 346 percent year over year, and adjusted earnings near 25.11 dollars a share, crushing the roughly 20.60 dollars analysts expected, per CNBC. More important than the print was the guide: Micron projected current-quarter revenue near 50 billion dollars, plus or minus 1 billion, far above the roughly 42.9 billion Street estimate. The company also revealed it has locked in 16 multi-year strategic supply agreements carrying a minimum of about 100 billion dollars in contracted revenue, effectively fixing historically high memory prices for years, per TechTimes. Shares jumped about 15 percent in after-hours trade, though the broader chip selloff capped the follow-through. The takeaway is a market splitting in two: memory, the supply-constrained bottleneck for AI, has pricing power, while much of the rest of the complex is being asked to justify its spending.

Alphabet's Worst Day in a Year on an AI Brain Drain

The AI talent war turned into a market event. Alphabet shares fell roughly 7 percent on Monday, June 22, the stock's worst day in more than a year, after two of Google's most prominent AI minds left for rivals within days of each other, per CNBC. Noam Shazeer, a co-lead of the Gemini models, departed for OpenAI, while Nobel laureate John Jumper, the DeepMind researcher behind the protein-folding breakthrough AlphaFold, left for Anthropic, per Bloomberg. The exits rattled investors because they raise a question no balance sheet can answer: whether the incumbent with the deepest research bench is losing the people who built its edge. We covered the immediate fallout in our June 22 evening review.

Apple and Microsoft Raise Prices as Memory Costs Bite

The memory supercycle has a downstream cost, and consumers are about to feel it. With DRAM and storage prices surging, Apple raised prices on Macs and iPads while Microsoft lifted Xbox pricing, moves that pressured Apple shares by about 6 percent during the week and underscored how Micron's pricing power flows straight into device margins, as flagged in our June 25 analysis. It is the same story from the other end of the supply chain: the AI build-out is no longer an abstract capex line, it is showing up on retail price tags.

Top Crypto Stories of the Week

Bitcoin Sinks to Its Lowest Since September 2024

Crypto had a miserable week. Bitcoin slid below 60,000 dollars and touched roughly 58,000 on Thursday, its lowest level since September 2024, before clawing back toward 59,600 by Friday, per Yahoo Finance. Ethereum fared worse, easing to about 1,569 dollars as roughly 1 billion dollars in leveraged futures positions were liquidated. The drivers were structural: persistent spot-ETF outflows, capital rotating out of crypto and into beaten-down AI names, and a stalled CLARITY Act in Washington that has left the regulatory picture murky. The same risk-off wave we described in Friday's evening review hit the majors hardest.

The Ethereum Foundation Cuts 20 Percent of Its Staff

In a symbolically loaded move for the second-largest crypto, the Ethereum Foundation said on June 23 it had cut about 54 jobs, roughly 20 percent of its workforce, and is slashing its operating budget by about 40 percent, per TechTimes. The foundation is reorganizing into a leaner set of protocol-focused clusters and shifting toward an endowment-style model designed to spend a far smaller share of its treasury each year. Supporters frame it as overdue financial discipline; skeptics see a development engine downshifting at a delicate moment for ETH's price.

Binance Prepares to Exit the European Union

The week's biggest regulatory shock came from the largest exchange. Binance told users it will stop providing crypto services across the EU from July 1 after failing to secure a license under the bloc's MiCA regime, per CoinDesk. Binance withdrew its application in Greece on June 24 after regulators raised concerns over anti-money-laundering controls and whether co-founder Changpeng Zhao could pass MiCA's fit-and-proper test, and it now plans to reapply in France, though any approval would land after the deadline. For users in France, Italy, Poland, Spain and beyond, it means a gap with no Binance access, and a reminder that Europe's crypto rulebook now has real teeth.

Altcoins Slide as XRP and Solana Track the Selloff

The pain was broad across the top 50. XRP slipped about 4.2 percent to near 1.06 dollars and Solana fell about 4.1 percent to roughly 66 dollars as the risk-off mood spared almost nothing, per Yahoo Finance. There were pockets of building beneath the surface, with Kraken's Ethereum Layer 2 network Ink moving onto Optimism's enterprise infrastructure, but price action was uniformly heavy. With bitcoin dominance firm and altcoins underperforming, the tape pointed to defensive positioning rather than the kind of rotation that signals a recovery.

M&A, Partnerships, Deals

Dealmaking stayed red hot even as public markets wobbled. The headline was SpaceX's 60 billion dollar all-stock acquisition of Cursor, the AI coding startup whose parent is Anysphere, the largest acquisition of a venture-backed startup ever, nearly double Google's 32 billion dollar purchase of Wiz, per Crunchbase. SpaceX, fresh off raising about 75 billion dollars in its record IPO, used its surging stock as currency; the shares had run up close to 50 percent from the 135 dollar offer before giving back 16.4 percent on June 22 amid the broad tech wobble. Elsewhere, Micron disclosed a strategic memory-supply agreement with Anthropic plus an investment in Anthropic's Series H round, tightening the bonds between the memory maker and the AI labs driving demand. For context, US startup M&A has now topped roughly 120 billion dollars this year, on pace for a record, with the Cursor deal alone accounting for about half of it.

Regulatory and Macro

The macro backdrop was defined by a more hawkish Federal Reserve and a sharp drop in oil. Following Kevin Warsh's first meeting as chair, the Fed's updated projections flipped from signaling a 2026 cut to flagging a possible hike, with nine of eighteen officials now penciling in at least one rate increase this year and the median dot rising to 3.8 percent. That higher-for-longer message gained force as a hot core PCE inflation reading near 3.4 percent landed during the week, keeping pressure on the longest-duration growth names. The relief valve was crude: WTI fell roughly 10 percent on the week to about 69.23 dollars a barrel, its steepest weekly drop in a month, as tankers kept transiting the Strait of Hormuz and a US-Iran framework drained the war premium, per CNBC. Cheaper energy should soften headline inflation ahead, even as core prices stay sticky; gold steadied near 4,068 dollars as a hedge.

Week Ahead: What to Watch

• June jobs report (Thursday, July 2): the BLS releases payrolls a day early ahead of the holiday, with consensus near 172,000; it is the swing factor for the hawkish Fed narrative and rate-hike odds.
• Binance EU deadline (June 30): services across the bloc are set to switch off from July 1, a live test of MiCA's enforcement and a potential liquidity event for European crypto users.
• ISM Manufacturing, JOLTS and confidence (June 30 to July 1): the labor and sentiment reads will shape expectations into payrolls; earnings from Nike and Constellation Brands offer a consumer pulse.
• Crypto support levels: whether bitcoin holds the 58,000 dollar area and whether spot-ETF outflows reverse will tell us if this was capitulation or a lower leg.
• Markets closed Friday, July 3: US equity and bond markets shut for Independence Day, thinning liquidity around the jobs print.
