Understanding ARK 21Shares Bitcoin ETF (ARKB)

ARK 21Shares Bitcoin ETF is one of the US Bitcoin ETFs — stock-market funds that hold real Bitcoin on behalf of their shareholders. It's run by ARK Invest & 21Shares. When money comes into the fund, it buys Bitcoin; when money leaves, it sells. You buy and sell its shares through a normal brokerage account, like any stock.

This page tracks the money flowing in and out of this one fund, and the big chart shows the running total of everything invested in it since January 2024. The percentages and “faster than usual” readings compare the fund against its own history, not against the other funds.

A single fund's numbers mix two things: how people feel about Bitcoin, and how this fund competes with the other twelve — fees, brand, and where it's easiest to buy. Money can leave one fund and walk straight into a cheaper one next door without anyone actually selling Bitcoin. For the market-wide read, start from the main Bitcoin ETF page.

These funds trade on the stock market, so they're closed on weekends and holidays — flat stretches on the chart are days the market wasn't open, not days nothing happened to Bitcoin.
