Ark Invest reduced its Bitmine holdings and deployed $31.5 million into Coinbase and Circle over a three-day trading window, according to trading disclosures from July 30, 2026. The fund sold 120,665 Bitmine shares for $2 million while buying 122,544 Coinbase shares for $18.6 million and 169,777 Circle shares for $12.9 million.
The rotation moves capital toward established exchange and stablecoin infrastructure plays. Ark bought Coinbase and Circle while Bitcoin and Ethereum prices have slid in recent weeks.
Ark Invest, which manages roughly $15 billion across its exchange-traded funds, has maintained active positions in crypto equities through multiple market cycles. The firm's flagship ARKK fund and sector-specific ARKF vehicle track technology and financial innovation plays, categories that crypto platforms and infrastructure firms occupy. Cathie Wood, the firm's chief investment officer, has publicly advocated for Bitcoin as a hedge against currency debasement, though her fund's equity bets include diversified crypto exposure beyond spot holdings.
Coinbase, the largest U.S. cryptocurrency exchange by trading volume, has faced regulatory scrutiny from the Securities and Exchange Commission over custody and lending products. Circle, an issuer of the USD Coin stablecoin and payments infrastructure provider, has expanded into cross-border settlement and treasury services. Bitmine, a holding company with stakes in mining operations and blockchain infrastructure, has seen its equity price decline alongside cryptocurrency valuations over the past month.

Ark Invest executed three trades over 72 hours. The purchases favor platform operators with regulatory clarity over exposure to mining assets tied directly to hash rate and energy costs. The Coinbase position size increased by roughly 7 percent on a per-share basis through the purchase, while the Circle addition represents a fresh accumulation at lower prices than similar positions made earlier in the year.
The trades occurred as both Coinbase and Circle stock traded near 52-week lows, driven by correlation with declining Bitcoin and Ethereum prices. Ark bought into weakness rather than at peaks. Bitmine's sale removes exposure to mining profitability that depends on both hardware efficiency and electricity arbitrage.
Ark's trading moves, selling mining exposure and rotating into exchange and stablecoin infrastructure, repeat positioning decisions the fund has made twice since 2024 when crypto equities faced similar drawdowns. Ark added 1.2 million shares to its Coinbase position in March 2024 during a comparable correction and sold mining-adjacent holdings both times.
