IBIT Draws $665.2 Million, Exceeding Net Inflows Into U.S. Bitcoin Funds
Key Facts
BlackRock's IBIT attracted net inflows of $665.2 million in the October 19, 2026 session, exceeding combined net inflows into U.S. spot bitcoin funds, according to Farside Investors. The group's total stood at $526.7 million, as withdrawals from rival funds offset some of the money attracted by BlackRock's fund. Fidelity's FBTC recorded net outflows of $83.6 million in the same session. Grayscale's GBTC saw withdrawals of $54.9 million, according to Farside. IBIT thus led the return to inflows for the category despite continued outflows from those two rivals.
The fresh inflows followed a session in which money flowed out of both BlackRock's fund and the group as a whole, according to Farside. On October 16, 2026, IBIT recorded net outflows of $71.8 million before returning to inflows in the following session. Combined net outflows from U.S. spot bitcoin funds totaled $82.4 million in that previous session. In terms of fund size, BlackRock reported IBIT's net assets at $65,704,430,346 as of October 19, 2026. The fund's sponsor fee disclosed in its prospectus is 0.25%, according to the company's official product page.
IBIT shares closed at $46.3 on October 19, 2026, according to EL7 data. Bitcoin's daily closing price was $81,938.4 on the same date, coinciding with the return of net inflows into U.S. funds. BlackRock reported daily trading volume in IBIT of 38,015,226 shares. That was below the 30-day average trading volume of 39,378,263 shares, according to company data dated October 19. The fund received fresh money in a session when trading in its shares was below its average over that period.
IBIT began trading on Nasdaq on January 11, 2024, according to BlackRock's launch announcement published by the exchange. Its launch followed the U.S. Securities and Exchange Commission's January 10, 2024 decision to approve the listing and trading of shares in a group of spot bitcoin products. In its statement issued on July 29, 2025, the SEC said in-kind creations and redemptions provide "flexibility and cost savings" for product issuers, authorized participants and investors. It added that this leads to "a more efficient market." In the same statement, the SEC announced an increase in position limits for certain bitcoin exchange-traded product options to the general limits, up to 250,000 contracts.
Alongside inflows into the existing fund, iShares is proposing another product under the ticker PBIT that uses options to provide conditional downside protection, according to its registration prospectus filed with the SEC. The prospectus states that the proposed fund does not invest directly in bitcoin or bitcoin exchange-traded products, instead gaining exposure through options. The strategy includes buying call options and selling other call options to finance part of the cost of the purchased options. In exchange for this financing, the sold options limit the fund's participation in gains in the reference asset above their strike price. The proposed structure thus combines conditional protection with giving up participation in gains above that price.
On the new product's filing process, iShares Trust filed a registration amendment for the iShares Managed Bitcoin Protection fund on October 19, 2026, according to SEC records. The filing places the proposed product's application on the same day as the inflows into IBIT. The registration filing elected for the amendment to become effective 75 days after filing, according to the document submitted to the U.S. Securities and Exchange Commission. That period relates to the effectiveness of the registration amendment for the fund proposing exposure through options. PBIT's trading debut remains without a confirmed date, as the elected effective period does not constitute a confirmed launch date.
