IBIT vs FBTC vs BITB: Bitcoin ETF Flow Comparison
IBIT, FBTC, and BITB give three different reads on spot Bitcoin ETF demand: BlackRock liquidity, Fidelity brokerage adoption, and Bitwise crypto-native participation.
Short Answer
BITB has the smaller cumulative outflow in the current CryptosEyes snapshot, not a positive-flow lead. Latest reported date: 2026-07-09. Cumulative flows: IBIT: -$1,815.9M, FBTC: -$432.3M, BITB: -$28.3M.
The broadest bullish signal is all three funds showing positive cumulative direction and recent participation. If only IBIT is carrying the move, ETF demand is more concentrated than the headline total may suggest.
IBIT facts use iShares sources, FBTC facts use Fidelity sources, and BITB facts use Bitwise sources. Their source dates differ, so AUM values should be read as issuer-stated context rather than a same-day ranking table. ETF flow values come from the CryptosEyes pre-generated Farside-based flow snapshot.

Cost Lens
On a $10,000 position, the listed annual cost is about $25 for IBIT, $25 for FBTC, and $20 for BITB before trading costs, taxes, and bitcoin price movement. That fee spread is not large enough to replace liquidity, platform, custody, and flow analysis.
What Matters
Signal Checklist
- Which fund leads cumulative flow in the current snapshot.
- Whether recent positive days are shared across all three funds.
- Whether the smaller issuer adds breadth or stays flat while the largest funds move.
Decision Rules
- Use IBIT to judge the dominant liquidity channel.
- Use FBTC to confirm that demand extends into Fidelity's brokerage ecosystem.
- Use BITB to test whether smaller, lower-fee issuer demand is joining the move.
What This Means
This three-way comparison is designed to avoid a common mistake: treating the Bitcoin ETF market as one fund. IBIT can dominate liquidity, FBTC can confirm brokerage demand, and BITB can show whether smaller issuer demand is participating.
Fees are close but not identical: IBIT and FBTC list 0.25%, while BITB lists 0.20%. The bigger distinction is market role. IBIT is the liquidity benchmark, FBTC is the Fidelity custody and brokerage channel, and BITB is the smaller crypto-specialist issuer with a public proof-of-reserve angle.
If all three funds show healthy participation, the ETF complex looks more resilient. If the table is led by one fund while the others are flat or negative, the headline flow number deserves more caution.

FAQ
Why compare IBIT, FBTC, and BITB together?
Together they represent three useful ETF demand channels: BlackRock institutional liquidity, Fidelity brokerage distribution, and Bitwise crypto-native issuer demand.
Which metric matters most in the three-way ETF comparison?
Cumulative flow shows the longer snapshot, but recent flow and positive-day consistency help separate durable demand from a few large prints.
Can one ETF dominate the Bitcoin ETF market signal?
Yes. That is why the comparison checks breadth. A market led by one ETF is different from a market where several issuers attract inflows together.
