Cathie Wood’s ARK ETFs add to Coinbase and Circle, trim Archer Aviation and Baidu

ARK Invest, led by Cathie Wood, adjusted its publicly traded “disruptive innovation” portfolios by adding to Coinbase Global and Circle Internet Group while trimming positions in Archer Aviation and Baidu, according to trading activity described in recent market coverage. The moves highlight how ARK’s exchange-traded funds continue to rebalance crypto-adjacent holdings during periods when digital-asset stocks can swing sharply.

On Thursday, June 4, 2026 and Friday, June 5, 2026, ARK Invest’s ARK Innovation ETF (ARKK) increased its holdings in Coinbase and Circle across the two sessions, according to trade disclosures cited by Stocktwits and summarized by market outlets. Over the two days, ARKK bought a total of 30,763 shares of Coinbase (NASDAQ: COIN) and 114,223 shares of Circle (NYSE: CRCL).

The share purchases were split by day: for Coinbase, ARKK bought 17,698 shares on Thursday and 13,065 shares on Friday. For Circle, ARKK purchased 13,973 shares on Thursday and 100,250 shares on Friday, with the larger buy attributed to a steeper drop in CRCL on Friday in the reporting.

On the sell side, ARKK reduced its position in Archer Aviation (NYSE: ACHR), cutting a combined 784,380 shares across the two sessions. ARKK also sold 457,754 shares of Baidu (NASDAQ: BIDU), described as its largest disposal by share count during the period, along with other trimming activity in additional holdings.

Coinbase, whose stock trades under COIN, operates a platform for buying, selling, transferring, and storing cryptocurrencies, including services aimed at institutional customers. Circle, whose stock trades under CRCL, is closely associated with USDC, a regulated stablecoin designed to be redeemable 1:1 for U.S. dollars, with Circle positioning USDC as digital-dollar infrastructure for payments and financial markets.

ARKK is an actively managed ETF that seeks long-term growth by investing primarily in companies tied to “disruptive innovation,” as defined by ARK. Among the themes the fund explicitly lists are digital assets and digital wallet-related technologies, a framing that helps explain why publicly traded crypto infrastructure names such as Coinbase and stablecoin-linked businesses such as Circle can remain central to the strategy.

The context for the trades was a volatile period for crypto-linked equities, with reporting pointing to market weakness around the same time ARK was rebalancing into COIN and CRCL. While the buys and trims are framed as thematic and responsive to market conditions, ARK typically does not publicly explain the intent behind each day’s specific share changes.

It is also important to note what is and is not disclosed. ARK’s trade notification materials describe that its published daily trade information is for informational purposes, may exclude certain transaction types (such as ETF creation/redemption activity), and can be “unofficial” and “unreconciled” until end-of-day accounting is completed. In addition, the market summaries do not consistently provide the exact execution prices or total dollar amounts for each named buy and sell, so only the share counts are reliably carried through across the reports. For an editor or reader tracking precision, the official end-of-day holdings and any accompanying ARK documentation provide the definitive accounting.
