Chip stocks log longest losing run since 2008 as weekend bets unravel
The Philadelphia Semiconductor Index fell for an eighth straight day on Friday, and on Saturday $52 million of leveraged crypto-exchange bets on chip shares were wiped out in 10 minutes.
The short answer
The Philadelphia Semiconductor Index fell 3.83% on Friday, its eighth losing session in a row and the longest streak since October 2008, leaving it 16% below its October 6 level. On Saturday, with Wall Street shut, about $52 million of leveraged chip-stock bets on crypto exchanges were force-closed in 10 minutes, CoinDesk reported.
What happened
The semiconductor index closed Friday at 11,137.29 after every one of its 30 members fell, according to Investing.com. Broadcom, Micron, AMD, Intel, Lam Research and KLA each dropped around 5%, and Arm slid about 7%. Then, on Saturday evening, a burst of selling hit perpetual futures, contracts on crypto exchanges that track stock prices around the clock. CoinDesk, citing CoinGlass data, said about $51.6 million of positions tied to chip stocks were liquidated between 21:22 and 21:32 UTC, roughly $38 million of it from traders betting on rises. The selling began on Binance and spread to Hyperliquid within seconds.
What it means
Chip stocks had a huge run before this. The index was up more than 60% this year by early October, carried by demand for AI chips and data centers. The reversal reflects several worries arriving at once: whether heavy, debt-funded spending on AI infrastructure will pay off, a hotter-than-expected US inflation reading that could keep interest rates high, and reports that Chinese memory maker CXMT has made technical progress. CoreWeave, an AI cloud company carrying about $50 billion of debt, fell 12% on Friday as its bond yields rose above 15%.
The damage was broad. Designers, memory makers and equipment suppliers all fell together, which suggests investors are questioning the whole spending cycle rather than any one company. Nvidia was a relative exception, slipping only 1.43% on Friday, according to 24/7 Wall St. AMD dropped 18.58% from its October 6 close to its October 16 close.
The weekend episode shows a newer feature of markets. Crypto exchanges now let traders bet on stocks such as SanDisk and SK Hynix, and on leveraged funds like SOXL, at any hour. When traders borrow to enlarge those bets, falling prices trigger automatic sell-offs that can feed on themselves. With US exchanges closed, there was no real share price for these contracts to follow, so prices were set purely by traders reacting to one another.
That makes Monday's open a useful test. Once real share prices return, it will become clear how far Saturday's contract prices drifted from where investors are actually willing to trade the stocks. A streak of losses does not by itself say anything about chipmakers' businesses, and the next round of big tech earnings and spending plans will matter more.
The bull case
Long losing streaks often follow strong runs, and the index is still well up for the year. Selling hit good and weak companies alike, so some of it may be investors trimming popular positions rather than a verdict on demand. Big AI chip orders, such as Anthropic's plans to deploy AMD processors from 2027, stretch over years. If the largest cloud companies hold their spending plans, sentiment could steady.
The bear case
The concerns behind the slide are real: debt-funded data center building, interest rates that may stay high and new competition from China in memory chips. Equipment makers are especially exposed if chip producers delay new factories. Weekend crypto trading in stock contracts adds another channel for leveraged selling, which could deepen swings when markets are already nervous.
Why it matters
For investors
Semiconductor stocks and funds such as SOXX and SOXL are most exposed, along with debt-heavy AI cloud firms like CoreWeave. Monday's open will show whether weekend contract prices predicted real share moves.
The wider context
Chipmakers now make up a large share of major stock indexes, so a slump can hit ordinary retirement and index funds. Leveraged trading around the clock can make those swings sharper.
Market impact
| Asset (ticker) | Possible move | Timeframe | Why |
|---|---|---|---|
| iShares Semiconductor ETF (SOXX) | ↓ Down | Short term | The index's eight-day slide reflects unresolved worries about AI spending and rates. |
| Direxion Daily Semiconductor Bull 3X Shares (SOXL) | ↓ Down | Short term | It led weekend liquidations and magnifies daily chip-stock losses threefold. |
| CoreWeave (CRWV) | ↓ Down | Short term | Bond yields above 15% signal stress over its roughly $50 billion of debt. |

Frequently asked questions
Why are chip stocks falling?
Investors are worried about the debt being used to fund AI data centers, a hotter-than-expected US inflation reading that could keep rates high, and reported progress by Chinese memory maker CXMT. The Philadelphia Semiconductor Index fell eight sessions in a row, its longest streak since 2008.
What are perpetual futures on stocks?
They are contracts on crypto exchanges that track a stock's price and trade around the clock, including weekends. Traders often use borrowed money, so when prices move against them their positions are closed automatically, which can trigger more selling.
How much have chip stocks fallen?
The Philadelphia Semiconductor Index has lost 16% since its last gain on October 6, closing Friday at 11,137.29. It had risen more than 60% this year through early October, so it remains well up for 2026 despite the slide.
