Since its launch in January 2024, the fund has accumulated over $63.9 billion in net inflows. This figure exceeds the total net inflows for the entire US spot Bitcoin ETF category, as competing funds have experienced net redemptions during the same period.

The fund maintains a sponsor fee of 0.25%, despite lower rates offered by some competitors. As of early September 2026, the 30-day net inflows for IBIT totaled $2.78 billion, solidifying its position as the primary gateway for institutional Bitcoin exposure in the US.
