ARK 21Shares Bitcoin ETF Sees $137.7M Inflow as Crypto Rally Heats Up

ARK 21Shares Bitcoin ETF saw a significant influx of capital on September 4, 2026, with $137.7 million in net inflows into the ARKB fund.

This move lifted assets under management to approximately $2.90 billion, representing about 4.7% of the fund's value turning over in a single day.

The surge in flows underscores how quickly sentiment can shift in crypto-linked products, as investors appear to be using the ETF structure to scale exposure rather than holding coins directly.

Such concentrated one-day moves often reflect a mix of momentum trading and renewed conviction that Bitcoin's current rally has more room to run.
