On the sell side, ARKG sold 498,068 shares of semiconductor-based life sciences company Quantum-Si Inc. (QSI), worth about $1.3 million. The company, known for its protein sequencing technology, has seen its stock under pressure amid slower adoption trends.

Though small, the trade extends ARK’s steady reduction in the stock over the past week. Brera, which formerly traded under the ticker BREA, changed its symbol to SLMT on October 3, 2025.
