After the results, KBW upgraded the stock to market perform from underperform and raised its price target to $160 from $93. Analysts at Wedbush, Canaccord Genuity, and JMP Securities increased its price target.

However, other analysts were less optimistic, with JPMorgan criticizing the exchange for its lack of clarity on how the spot bitcoin exchange-traded funds boosted its business. Mizuho was also critical of Coinbase’s performance and maintained its underperform rating and $60 price target.

ARK also sold $6.72 million shares of trading platform Robinhood (HOOD) on Friday.
