Twitter is ARKK's thirty-fourth largest investment among a total of 58 stocks and ARKW's eighth largest investment among a total of 53 stocks.

Twitter reported year-over-year revenue growth of 28% to $1.04 billion in the first quarter, lower than peers. The social media company grew its monetizable daily active users (mDAUs) 20% year-over-year to 199 million, just shy of the 200 million expected.

“Given the recent product announcements centered around Twitter Spaces, a live audio feature, we believe that future user growth could surprise to the upside,” Ark said in a note to investors over the weekend.
