ARK Invest ramped up its exposure to crypto-related equities on Thursday, deploying approximately $18 million across three digital-asset-focused companies.

The largest portion of the allocation went to trading platform Robinhood (HOOD), where ARK purchased $12 million worth of shares. The firm also invested $4 million in ether treasury company Bitmine Immersion Technologies (BMNR) and added a $2 million stake in cryptocurrency exchange operator Bullish (BLSH), according to a disclosure issued Friday.

The latest buy marks ARK’s 10th consecutive session accumulating Bullish, the parent company of CoinDesk. Bullish shares slipped 0.53% to close at $31.71. The stock has recovered from a Feb. 5 low near $24 and has hovered around the $30 level in recent days, though it remains more than 16% lower on the year.

Robinhood fell 8.9% to end Thursday at $71.12 amid a broader sell-off in U.S. technology stocks, a move that also pressured Bitcoin. In contrast, Bitmine outperformed the wider market, rising 1.39% to close at $19.74.
