Cryptocurrency markets experienced a downturn as macroeconomic conditions weakened, with Bitcoin (BTC) falling 0.9%. This decline coincided with drops in major indices such as the S&P 500 and Nasdaq 100. Contributing to the risk-off sentiment were the Balancer exploit and a disappointing October ISM Manufacturing index reading of 48.7. In contrast, Bitcoin miners IREN and CIFR saw significant gains after announcing substantial AI infrastructure deals. IREN secured a $9.7 billion, five-year contract with Microsoft, while CIFR entered a $5.5 billion, 15-year agreement with AWS. These deals underscore the increasing involvement of BTC miners in the AI sector. Meanwhile, Solana (SOL) underperformed, trading below its October 10 low, with ecosystem tokens nearing all-time lows despite robust ETF inflows.
