Cathie Wood's ARK Invest executed significant portfolio rebalancing on December 12, 2025, continuing a week-long trend of reducing its position in Tesla while increasing investments in fintech and cryptocurrency-related assets. The firm sold 87,993 shares of Tesla (TSLA) across its ARKK and ARKW exchange-traded funds, a transaction valued at $39.3 million. This sale is part of a broader pattern of the fund decreasing its exposure to the electric vehicle maker.
On the buying side, ARK Invest made substantial purchases in Robinhood Markets (HOOD) and its own spot Bitcoin ETF, ARKB. The firm acquired 108,557 shares of Robinhood worth $13.4 million, adding to recent purchases. This move came as Robinhood's stock price had declined by 9.1%, and the brokerage firm is now the seventh-largest holding in both the ARKK and ARKW funds. Separately, ARK purchased 13,700 shares of its ARKB Bitcoin ETF, valued at approximately $417,000, for its Ark Next Generation Internet and Ark Fintech Innovation funds. This acquisition occurred despite ARKB experiencing net outflows of $16.4 million the previous day, following Bitcoin price volatility after a Federal Open Market Committee (FOMC) meeting.
ARK also diversified into other sectors, buying 97,406 shares of fintech firm Block Inc. (SQ) for $6.2 million, 11,489 shares of agricultural equipment maker Deere & Co. for $5.5 million, and 16,547 shares of defense technology company L3Harris Technologies for $4.8 million. Concurrently, the fund reduced holdings in other areas, selling 55,461 shares of semiconductor testing company Teradyne for $11.3 million, as well as smaller positions in SoFi Technologies, Iridium Communications, and Ibotta Inc.
The trades illustrate ARK Invest's ongoing strategy to ensure no single holding exceeds 10% of a fund's value, reallocating capital from electric vehicles and certain technology hardware into fintech, digital financial services, and cryptocurrency exposure through its Bitcoin ETF.
