The ProShares exchange-traded fund, which began buying and selling in October 2021 as the primary U.S. bitcoin-linked ETF, now accounts for five.03% of the ARK Subsequent Era Web ETF (ARKW), its sixth-largest holding. The fund now not holds any GBTC shares, with the final reported sale on Dec. 20. At slightly below 12%, Coinbase stays the fund’s largest holding even after Wednesday’s sale of 148,885 shares.
