Ark Invest buys more Bitmine and Bullish shares as crypto-linked stocks slide

Cathie Wood’s firm bought 212,314 shares of Bitmine across three of its exchange-traded funds, worth about $4.2 million based on the close. Bitmine finished the session up 1.4% at $19.74 but remained down 36.7% over the past month.

Ark’s daily trading disclosure also showed purchases of 74,323 shares of Bullish worth about $2.4 million. The buy marked the 11th consecutive trading day Ark added Bullish shares. Bullish closed down 0.5% at $31.71 and was down 18% over the past month.

Ark also bought 174,767 shares of Robinhood worth about $12.4 million, whose broader operations are examined in our Robinhood review. Robinhood fell 8.9% in the session, extending its month-to-date decline to about 40%.

Ark maintains a portfolio rule that limits any single holding to no more than 10% of a fund, which can drive rebalancing as prices move. Bullish was the ninth-largest holding in the ARK Fintech Innovation ETF (ARKF) at about a 3.4% weighting, valued near $30 million.

The buying came as risk assets slid. The Dow Jones Industrial Average fell 1.3% on 12 February 2026, the Nasdaq Composite dropped 2%, and the S&P 500 declined 1.6%. Bitcoin fell about 1% over the past 24 hours to $66,754, while ether slipped 0.7% to $1,962.

As GNcrypto wrote on 16 January 2026, Ark Invest chief executive Cathie Wood argued in the firm’s 2026 Outlook that bitcoin’s fixed issuance schedule makes it scarcer than gold because supply cannot respond to higher prices. The report contrasted gold’s stronger 2025 performance with bitcoin’s decline, and framed the supply cap as a key difference in how the two assets absorb shifts in demand.
