iShares Bitcoin Trust ETF
The largest and most liquid U.S. spot bitcoin ETF.
$10,000 invested, compounded for 30 years.
Compound-fee impact at an assumed 8% annual return. The expense-ratio benchmarks (lowest + category median) come from the live cohort in /compare/etfs; the 8% return is illustrative, not a forecast.
The full custody chain.
When you buy IBITshares, you don't hold Bitcoin — you hold a claim on the trust. The trust holds a claim on the custodian. The custodian holds the actual keys.
How IBIT compares to the other ETFs.
IBIT is everywhere.
Listed on Nasdaq, available in essentially every U.S. brokerage. Compatible with IRA, 401(k), and HSA accounts.
The 8-factor breakdown.
Annual sponsor fee — the largest, most certain drag on returns
Trading depth and spreads for getting in and out at scale
How tightly the fund tracks spot bitcoin
Market-price premium or discount to NAV — arb efficiency
Assets under management — viability and closure risk
BlackRock is the world-scale asset manager behind iShares, with deep ETF distribution, capital-markets support, and institutional relationships.
Clarity of fee structure — waivers, expirations, hidden costs
IBIT uses Coinbase Prime and Coinbase Custody infrastructure for bitcoin custody, a common institutional custody stack among U.S. spot bitcoin ETFs.
Overall score = 7*25% + 10*20% + 8*12% + 9*10% + 10*13% + 10*8% + 9*7% + 8*5% = 8.7. The calibrated fee rubric treats 25 bps as adequate but not elite; IBIT still leads because liquidity, AUM, issuer quality, and execution depth are category-leading.
Questions readers actually ask about IBIT.
Is owning IBIT the same as owning Bitcoin?
Functionally for most purposes, yes — you get price exposure backed 1:1 by BTC held in cold storage. Mechanically, no — you own shares in a trust, not the underlying Bitcoin. The difference matters in three scenarios: (1) self-custody control, (2) using BTC as collateral elsewhere, (3) keeping access if your brokerage fails.
Why pick IBIT over a cheaper competitor like Bitwise's BITB?
IBIT's fee premium pays for the deepest liquidity in the category. If you're trading any meaningful size, the spread tightness more than makes up for the higher expense ratio.
Does IBIT pay dividends?
No. The trust holds Bitcoin, which doesn't generate yield. All returns come from price appreciation of the underlying.
What happens to my IBIT if BlackRock fails?
The Bitcoin backing IBIT is held by Coinbase Prime as a qualified custodian, legally separate from BlackRock's operating funds. The trust's assets would not be claimable by BlackRock's creditors.
Can I buy IBIT in my 401(k)?
Depends on your plan. Most modern plans that allow individual brokerage windows support it. Many default 401(k) menus don't.
