BlackRock Lowers IBIT In-Kind Conversion Minimum to $1 Million

BlackRock has reduced the minimum size for in-kind conversions on its iShares Bitcoin Trust (IBIT) to $1 million, down 96% from the previous $25 million requirement. The move broadens access to the ETF's redemption and creation process and is expected to improve how closely IBIT tracks spot bitcoin. Robbie Mitchnick, BlackRock's head of digital assets, confirmed the new threshold in a Bloomberg Television appearance, saying: "Bitcoiners can do inkind exchanges of BTC for IBIT for $1 million minimum now. It used to be $25 million." In-kind conversion allows an authorized participant to deliver bitcoin and receive IBIT shares (or redeem shares for bitcoin) rather than settling in cash. Authorized participants are typically large banks or trading firms permitted to create and redeem ETF shares directly with the issuer. Regulators approved in-kind mechanisms for spot bitcoin ETFs earlier in 2026, and BlackRock has been expanding access since. Under the old $25 million minimum, the process largely catered to major market makers and institutional trading desks. Cutting the bar to $1 million opens the door to a wider set of authorized participants and midsized institutions, increasing arbitrage activity that can correct pricing gaps faster. Over time, that dynamic can support better secondary-market liquidity and narrower bid-ask spreads for everyday shareholders. The change also carries tax implications: institutions that already hold bitcoin may be able to move into IBIT via in-kind exchange without triggering a taxable cash sale, an advantage not available to cash-settled structures. BlackRock has indicated it plans to keep lowering the threshold, with Mitchnick previously saying the firm hopes to make in-kind conversion available "at any transaction size." The adjustment comes as IBIT continues to gather assets. The fund drew $479 million over a three-day stretch last week, representing about 76% of total spot bitcoin ETF inflows during that period. Across the category, spot bitcoin ETFs recorded five straight days of net inflows in early August, bringing in more than $750 million for the week even as bitcoin traded unsteadily below $65,000. Competition has also highlighted diverging investor preferences. Grayscale's GBTC has seen about $27.47 billion in cumulative outflows since its 2024 conversion into an ETF, with many investors shifting toward lower-fee options such as IBIT. By making in-kind activity cheaper and more accessible, BlackRock strengthens its position, particularly for institutions that already hold bitcoin and can transition into IBIT shares without first selling into cash. Since launching in January 2024, IBIT has become the largest spot bitcoin ETF by assets. BlackRock has positioned it as a centerpiece of its broader digital-assets strategy, which includes an ether ETF and expanding tokenization initiatives. Market observers expect further refinement of creation and redemption mechanics as the spot bitcoin ETF market matures and trading volumes rise. Analysts also point to in-kind activity as a metric worth watching, as a higher share of in-kind creations and redemptions is often viewed as a signal of improving market efficiency.
