Best Brokerage for Bitcoin ETF (2026 Comparison)
A practical comparison of US brokers for buying Bitcoin ETFs — Fidelity, Schwab, IBKR, Robinhood, and the one that quietly does not support them.
TL;DR. Fidelity, Charles Schwab, E*TRADE and Interactive Brokers all support spot Bitcoin ETFs across all account types (taxable, IRA, 401(k) where applicable). Robinhood and Webull support them in taxable and Roth/IRA. Vanguard does not offer spot Bitcoin ETFs on its platform — by far the most consequential broker decision for Bitcoin ETF investors. If your retirement assets are at Vanguard, you'll need a second brokerage for Bitcoin ETF exposure.

Vanguard's position
Vanguard publicly declined to offer spot Bitcoin ETFs on its platform when they launched in January 2024, citing the firm's view that cryptocurrencies do not fit its long-term, fundamentals-based investment philosophy. The position has not changed as of 2026.
This is the single most consequential broker decision for retirement-focused investors. Many investors who hold their core 401(k) and Roth at Vanguard have opened a second brokerage account (Fidelity or Schwab are the natural choices) specifically for Bitcoin ETF exposure. There is no friction to having multiple brokers.
The clean defaults
Fidelity — best all-around
Supports all spot Bitcoin ETFs (including its own FBTC), all account types, fractional shares, and integrated tax reporting. If you have any other Fidelity assets, consolidating here is the path of least resistance. See Fidelity FBTC review.
Charles Schwab — best for active traders
Identical functional support to Fidelity, plus thinkorswim platform for serious traders. Schwab does not have its own Bitcoin ETF, so the broker is fully agnostic on fund selection.
Interactive Brokers — best for international and pro investors
Tightest bid-ask spreads on Bitcoin ETF orders thanks to IBKR's smart-routing infrastructure. Supports international accounts (UK, EU, Singapore). Slightly higher commission tier ($0 with IBKR Lite, fractional cents per share with IBKR Pro).
Mobile-first options
Robinhood and Webull both support spot Bitcoin ETFs in regular and Roth IRA accounts. UX is simpler than Fidelity or Schwab; account types are fewer (no SEP-IRA, no 401(k) administration). Fine for casual investors; less ideal if you need consolidated retirement planning.
For 401(k) participants
Your 401(k) ability to buy a Bitcoin ETF depends on the plan administrator's investment menu. The full picture is in Bitcoin ETF in a 401(k); the short version: Fidelity-administered plans often have Bitcoin ETF availability; Empower, Voya, and Vanguard-administered plans usually do not.
The one feature that matters most
For most retail investors choosing a broker: fractional share support. With single shares costing $40–$80 in 2026, fractional capability lets you buy $50 or $100 chunks rather than rounding to whole shares. Fidelity, Schwab, Robinhood, Webull and IBKR all support fractional Bitcoin ETF shares. E*TRADE and Merrill Edge do not.
FAQ
Why does Vanguard not offer Bitcoin ETFs?
Vanguard publicly stated that cryptocurrencies do not align with its long-term, fundamentals-based investment philosophy. The firm has not changed its position since the January 2024 spot Bitcoin ETF approvals. Vanguard customers who want bitcoin exposure typically open a second brokerage at Fidelity or Schwab.
Which broker has the lowest cost for buying Bitcoin ETFs?
All major US brokers (Fidelity, Schwab, E*TRADE, Robinhood) offer zero-commission ETF trading. The differentiator is bid-ask spread quality on execution: Interactive Brokers typically has the tightest spreads via smart routing, but the difference vs Fidelity or Schwab is small for typical retail order sizes.
Can I buy a Bitcoin ETF in my employer 401(k)?
It depends on your plan administrator and the menu they offer. Self-directed brokerage windows (available in some plans) let you buy any ETF including Bitcoin funds. Standard plan menus often exclude crypto products. Check your plan documents or contact the administrator.
Do I need a special account to buy a Bitcoin ETF?
No. A spot Bitcoin ETF is a standard security and trades in any regular brokerage account — taxable, Roth IRA, traditional IRA, SEP-IRA, or 401(k) where the plan menu allows. No crypto account, no wallet, no special permissions.
Should I open a second brokerage just for a Bitcoin ETF?
If your existing broker doesn't support spot Bitcoin ETFs (most relevantly Vanguard), yes — opening a free secondary account at Fidelity or Schwab is the standard solution. There is no fee, no downside, and you keep retirement assets at your primary broker.
