Key Takeaways
- • Trading volume in BlackRock's iShares Bitcoin Trust (IBIT) does not equal net inflows; a $10 billion day of IBIT turnover may largely reflect existing shareholders trading shares with one another, not new Bitcoin purchases.
- • New Bitcoin is acquired only when share demand pushes prices high enough to require creation of new shares, which authorized participants execute in baskets; per BlackRock's fund page, IBIT's basket bitcoin amount was 22.64 BTC as of Sept. 24, 2026, with a basket value of roughly $1.91 million.
- • A genuine $10 billion net inflow would require thousands of creation baskets over time rather than a single purchase order, spreading the buying across time and venues.
- • Authorized participants may source Bitcoin gradually, through OTC liquidity, hedging, or cash-based creation, which reduces the likelihood of an abrupt price spike but does not eliminate price impact.
- • Bitcoin's liquidity is deep relative to most crypto assets, so a sustained $10 billion in net inflows would probably move the price, though not necessarily in a simple or immediate way.
Summary
The Coinpaper article examines how a large inflow into BlackRock's spot Bitcoin ETF would translate into actual Bitcoin purchases. Its central point is that ETF demand and spot Bitcoin buying are linked through a creation mechanism rather than one-to-one in real time. Most IBIT shares trade between investors on Nasdaq, and in those transactions no new Bitcoin is bought. Only when demand is strong enough that new supply is needed do authorized participants create new shares in large blocks, known as baskets, and source the underlying Bitcoin.
The article cites BlackRock's official fund page, which lists IBIT's basket bitcoin amount at 22.64 BTC as of Sept. 24, 2026, with a basket value of roughly $1.91 million. On that basis, the publication notes that a net $10 billion inflow would require thousands of creation baskets accumulated over time rather than a single large order.
The piece stresses the distinction between trading volume and net flows. A $10 billion day in IBIT turnover does not necessarily mean BlackRock bought $10 billion of Bitcoin, since much of that volume may simply be existing holders trading shares. Authorized participants can spread their sourcing across time, use over-the-counter liquidity, hedge exposure, or deliver cash through the creation process, which reduces the risk of a sudden vertical move in the Bitcoin price.
The article concludes that a $10 billion inflow would probably move Bitcoin, though not always in a simple or immediate way. Bitcoin trades across exchanges, OTC desks and institutional venues, and its liquidity is deep compared with most crypto assets. Still, depth is finite: if sellers are unwilling to part with BTC at prevailing prices, the market generally has to adjust upward. Sustained net inflows would create real spot demand even if purchases are distributed across venues and time.
