Ark 21Shares Bitcoin ETF — Investor Relations & Filings
The ARK 21Shares Bitcoin ETF (ARKB) is an exchange-traded fund designed to provide direct exposure to bitcoin. The fund's investment objective is to track the performance of bitcoin, as measured by the CME CF Bitcoin Reference Rate - New York Variant. To achieve this, the trust physically holds bitcoin as its underlying asset. As a passively managed fund, it does not actively trade or take positions to mitigate price volatility. ARKB offers investors a vehicle to gain exposure to the price movements of bitcoin within traditional investment portfolios and brokerage accounts, eliminating the complexities associated with the direct purchase, storage, and safekeeping of the cryptocurrency. The fund is sponsored by 21Shares US LLC with marketing assistance from sub-adviser ARK Investment Management LLC.
