The Promised Decoupling Fails to Materialize: Why BTC Has Returned to the Shadow of US Stocks Amid the AI Sell-Off

Bitcoin fell about 5.5% on Nov. 5 to a closing price near $76,000 and an intraday low of roughly $75,200 as a broader AI-driven selloff in technology stocks spilled into crypto markets. The drop came a day after BTC had rebounded to about $81,000 alongside a 3% gain in the Dow, and it tracked a 5.52% decline in the Nasdaq Composite and a more than 12% slump in a semiconductor ETF, with Nvidia down 9.26% and AMD down 17.26%. More than $1 billion in crypto positions were liquidated within 24 hours, nearly 90% of them longs, affecting about 210,000 traders, while U.S. spot bitcoin ETFs recorded roughly $1.5 billion in net outflows between Oct. 30 and Nov. 5, including $643 million on Oct. 30 alone. The episode undercuts the recent thesis that bitcoin was decoupling from tech stocks and aligning with gold, a view Grayscale's Zach Pandl advanced in August when BTC-gold correlation reportedly rose above 50% and BTC-Nasdaq 100 correlation fell to about 33%; K33 Research had already flagged in October that the two-week return correlation with the Nasdaq had risen again. Bitcoin and gold are both down for the year, with BTC off about 13% year-to-date as of Nov. 5 and gold roughly 27% below its January high near $5,600, while short-term Treasuries and commodities have gained. The key question is whether ETF flows stabilize and whether bitcoin resumes trading as a growth asset or a hedge, with volatility expected to expand after a period of compression.
