BlackRock reduced the in-kind transfer minimum on its iShares Bitcoin Trust (IBIT) to $1 million from $25 million, a 96 percent cut. The change lets authorized participants create or redeem ETF shares using actual Bitcoin at a fraction of the prior threshold.
BlackRock cut the in-kind transfer minimum on its iShares Bitcoin Trust (IBIT) to $1 million from $25 million, a 96 percent reduction that lets authorized participants create or redeem shares with actual Bitcoin at a fraction of the prior threshold.
For most of IBIT's existence, deliveries had to happen in cash. An authorized participant wanting to create shares would wire dollars, and BlackRock's team would buy Bitcoin on the open market. The reverse happened on redemptions. The SEC approved in-kind transactions for spot Bitcoin ETFs in mid-2025, ending the cash-only requirement that had governed the first generation of these products since their January 2024 launch, according to the regulator's rule change. BlackRock had filed for the capability in January 2025, and the initial $25 million minimum was tied to early net asset value assumptions in the fund's original filings.
IBIT's current indicative basket consists of 40,000 shares representing approximately 22.65 BTC, valued at roughly $1.47 million at recent prices. Under the old $25 million floor, an authorized participant needed a position about 17 times the size of a single creation basket to use the in-kind mechanism. The fund trades on Nasdaq with a 0.25 percent sponsor fee.
IBIT's $48 billion-plus asset base makes it the largest spot Bitcoin ETF, and the lower threshold could increase creation and redemption activity, tighten the fund's tracking of Bitcoin's price, and improve arbitrage efficiency. The change also pressures competitors such as Fidelity's FBTC and ARK 21Shares' ARKB to match the operational flexibility.
The reduction reflects a broader shift among US spot Bitcoin ETFs toward hybrid transaction models that blend cash and in-kind mechanisms. For investors, the efficiency gains from a wider pool of authorized participants can translate into tighter bid-ask spreads and reduced premium or discount to net asset value. The $1 million threshold still targets institutional-sized participants rather than retail investors, but the operational improvements benefit all shareholders through improved market making.
When BlackRock adjusts its parameters, counterparties, competitors, and market makers all recalibrate accordingly. The move could also encourage other issuers to lower their own in-kind thresholds, further integrating Bitcoin ETFs into the mainstream financial infrastructure.
