Summary
Ark Invest, the investment firm led by Cathie Wood, executed a significant portfolio rebalancing on July 29, 2026, reducing its exposure to cryptocurrency-linked equities while simultaneously increasing its position in SpaceX. According to reporting on July 30, Ark sold 120,665 shares of BitMine through the ARK Innovation ETF in a transaction valued at approximately $2 million. The sale was accompanied by smaller liquidations: 13,403 shares of Block, 12,561 shares of Robinhood, and 11,314 shares of Bullish, collectively trimming the firm's crypto-sector footprint.
BitMine, which holds the distinction of being the world's largest corporate holder of Ether, experienced a 5.6% share price decline to $16.59 following Ark's sale. The other three divested stocks—Block, Robinhood, and Bullish—also declined on the trading day, suggesting broader sector weakness or profit-taking activity.
In contrast to these crypto-sector reductions, Ark purchased a combined 128,932 SpaceX shares across several ETFs for approximately $14.5 million. This acquisition occurred despite SpaceX shares trading at $112.55, representing a 16.6% discount to the company's initial public offering price of $135, suggesting Ark viewed the dip as an opportunistic entry point for accumulation.
The rebalancing activity aligns with Ark Invest's standard portfolio management discipline: the firm maintains a policy that no single stock position may exceed 10% of any individual ETF's portfolio. This mechanism-driven adjustment ensures diversification compliance across its fund family while allowing tactical adjustments in response to market movements.
