Key Points:
- Bitcoin fell as much as 2.9% to approximately $81,600 as weaker Asian equities and declining Nasdaq futures pressured risk-sensitive assets.
- DeFi tokens and smaller cryptocurrencies suffered sharper losses, with the CoinDesk 80 falling around 3.2% and the DeFi Select Index declining 5.6%.
- Crypto derivatives trading activity increased while open interest declined, suggesting traders were repositioning and closing contracts rather than broadly adding fresh exposure.
Bitcoin dropped below $82,000 on Thursday, October 22, 2026, as renewed doubts over artificial intelligence spending weighed on technology stocks and broader market sentiment. The decline extended across digital assets, with decentralized finance tokens and smaller cryptocurrencies underperforming Bitcoin. Despite more than $1 billion in reported spot Bitcoin ETF inflows over the first three days of the week, the market remained vulnerable to shifting risk appetite and leveraged-position adjustments.
AI Concerns Pressure Bitcoin and Global Equities
Bitcoin (BTC) fell as much as 2.9% to around $81,600 from midnight UTC, its steepest decline in two weeks, before trading near $81,451.36 in the supplied market snapshot. Mixed earnings reports from Tesla and Meta Platforms revived concerns about the returns on AI-related spending, contributing to weakness in Asian equities and U.S. stock futures.
China’s stock market entered bear-market territory, while Hong Kong’s Hang Seng Index declined more than 3%. South Korea’s Kospi fell 3.5%, and Japan’s Nikkei 225 lost 2.7%. Nasdaq 100 futures dropped 1.32%, while S&P 500 futures declined 0.66%.
The simultaneous weakness in equities and cryptocurrencies highlights how digital assets remain sensitive to changes in risk appetite. Bitcoin’s decline does not prove that AI spending concerns directly caused crypto selling, but the timing suggests that investors were reassessing exposure across risk-sensitive markets.
DeFi and Altcoins Bear the Brunt of the Sell-Off
Losses were more severe outside Bitcoin. The CoinDesk 80 Index fell approximately 3.2%, compared with a 2.5% decline in the CoinDesk 5 Index. Ether (ETH) lost 2.6% to around $2,400, while Solana (SOL) declined 2.4% to approximately $104.
Decentralized finance was among the weakest sectors, with the DeFi Select Index dropping 5.6%. Curve (CRV) fell 8.2% to around $0.37, Ethena (ENA) declined 7.2%, and Uniswap (UNI) lost 5%. UNI remained down roughly 20% for October despite record fee revenue reported for September, illustrating that strong activity metrics do not necessarily translate into short-term token-price gains.
Other tokens also weakened. Worldcoin (WLD) dropped 7.3%, while Pump.fun (PUMP) fell 6%. Celestia (TIA) declined 3.7% ahead of a scheduled October 31 unlock of 5.58 million tokens. These moves show how sector-specific supply events and sentiment can compound broader market pressure.
ETF Inflows Meet a More Cautious Derivatives Market
U.S. spot Bitcoin ETFs attracted more than $1 billion during the first three days of the week, according to SoSoValue data cited in the report. Those inflows indicate continuing demand through exchange-traded products, but they did not prevent Bitcoin from retreating as wider markets weakened.
Crypto derivatives trading volume surged 19% to $226.6 billion, while open interest declined 2.46% to $141.8 billion. Liquidations increased 52% to $431.1 million. The combination suggests elevated trading and position turnover, although these aggregate figures alone cannot establish every trader’s motive or whether all participants were reducing risk.
Funding rates remained only slightly positive for Bitcoin and Ether, indicating no pronounced directional imbalance in the reported data. Meanwhile, options volatility gauges for both assets remained near their yearly lows, even as short-term price declines intensified. That contrast suggests options markets had not broadly repriced for a major volatility event at the time of the report.
What Investors Should Watch Next
Market attention will turn to U.S. initial jobless claims and whether technology shares stabilize after renewed questions about AI investment returns. Investors will also be watching ETF flows, derivatives positioning and the performance gap between Bitcoin and altcoins. Sustained institutional inflows could offer support, but the latest session shows that capital entering Bitcoin products does not eliminate broader macroeconomic or market-structure risks. Until sentiment improves and selling pressure eases, DeFi and other higher-volatility tokens may remain particularly sensitive to further shifts in risk appetite.
