Bitcoin-to-IBIT Swaps Start at $1–2M as Security Drives Demand
Bitcoin holders can reportedly arrange IBIT conversions from $1–2 million, as BlackRock cites record interest driven by security and simpler custody.
Key Notes
- Reported minimums for arranging Bitcoin-to-IBIT conversions have fallen from about $30 million to $1–2 million.
- BlackRock says interest is at a record, with security the leading motivation.
- Intermediaries set conversion thresholds, while ordinary IBIT share purchases do not require a million-dollar investment.
Large Bitcoin holders are seeking to exchange their coins for BlackRock’s iShares Bitcoin Trust shares at record levels, as security concerns make professionally managed custody more attractive.
The minimum for arranging these conversions has fallen from roughly $30 million initially to about $1 million–$2 million, according to a Barron’s report cited by Bitcoin Magazine. The thresholds are set by intermediaries facilitating the transactions, rather than a minimum investment imposed on everyone buying IBIT.
Robbie Mitchnick, BlackRock’s head of digital assets, told Barron’s that interest was the strongest the firm had seen. He identified “security and peace of mind” as the largest single motivation for holders making the switch.
How Bitcoin Becomes IBIT Shares
An in-kind conversion lets an investor deliver existing Bitcoin through an intermediary and receive newly created fund shares. The holder gains exposure through a securities account, without first selling the coins for cash.
Galaxy Digital, Talos and Virtu handle these arrangements, according to the report. The lower threshold broadens access beyond the largest individual holdings, although it still involves a substantial amount of capital.
The SEC approved in-kind transactions for Bitcoin and Ether products in July 2025. IBIT’s quarterly filing specifies that direct creations and redemptions occur through authorized participants in baskets of 40,000 shares.
BlackRock valued one basket at approximately $1.69 million on November 9. That value changes with the fund’s assets and is separate from an intermediary’s commercial minimum. Ordinary investors can buy existing IBIT shares on Nasdaq without committing millions of dollars.
Custody Responsibilities Shift
The appeal is straightforward: shareholders no longer have to safeguard the private keys controlling the underlying Bitcoin. They instead rely on the trust’s custody arrangements and their brokerage access.
The quarterly filing names Coinbase Custody as the Bitcoin custodian and Anchorage Digital as an additional custodian. It says the sponsor had no plans at that time to move Bitcoin to Anchorage. Appointing another provider does not establish that holdings are already divided between them.
CoinScreamer’s earlier custody risk analysis examined why institutional storage still depends on secure signing and approval systems. It identified no evidence of an IBIT breach.
IBIT also carries a 0.25% annual sponsor fee, according to its fund page. Converting changes how Bitcoin exposure is held, while leaving the investor exposed to movements in Bitcoin’s price.
Conversion Demand and Fund Outflows
Record interest in conversions can coexist with net withdrawals. On November 9, IBIT recorded approximately $213.2 million in net outflows, as CoinScreamer reported in its ETF flow coverage.
Conversion demand describes one route into the fund. Net flows reflect the balance of creations and redemptions. Moving Bitcoin already owned into IBIT does not, by itself, demonstrate an equivalent fresh purchase on a crypto exchange.
