Summary
Cathie Wood's ARK Invest executed a comprehensive exit from cryptocurrency-linked holdings during the week of September 18, 2026, liquidating positions across direct bitcoin exposure, exchange infrastructure, and stablecoin protocols simultaneously. The flagship transaction involved the sale of more than 1.5 million shares of the ARK 21Shares Bitcoin ETF (ARKB) distributed across the ARK Next Generation Internet ETF (ARKW) and ARK Fintech Innovation ETF (ARKF) on Monday, representing the largest single trade by volume for the week.
The cryptocurrency sector retreat extended beyond direct bitcoin exposure into related infrastructure and service providers. ARK divested from Circle Internet Group (CRCL), which experienced the steepest decline at over 12% from Monday onward, followed by Coinbase Global (COIN) at 9%, with both Bitmine Immersion Technologies (BMNR) and Bullish (BLSH) declining approximately 7%. This coordinated exit eliminated ARK's exposure across three distinct crypto segments: direct bitcoin holdings through ARKB, cryptocurrency exchange platforms through Coinbase and Bullish, and stablecoin infrastructure via Circle. The disposition pattern suggests a systematic de-risking strategy rather than isolated position management.
Notably, ARK reversed course on CoreWeave (CRWV) within the same trading week, selling 64,923 shares on Monday before aggressively buying back 239,083 shares across ARKK and ARKW on Thursday, representing approximately $24.7 million in repurchases. This intra-week reversal signals either a tactical reset following initial profit-taking or a reconsidered conviction in the AI infrastructure provider following market-driven repricing.
The portfolio activity extended beyond the cryptocurrency sector, with ARK simultaneously trimming substantial positions in large-cap technology and biotechnology holdings including Palantir, Shopify, Tempus AI, Amazon, AMD, and 10x Genomics. The ARKB Bitcoin ETF declined 3% during the week, while retail sentiment indicators on Stocktwits remained in bearish territory, reflecting broader portfolio repositioning pressure.
