Which one should you actually pick?
Interactive Brokers. Serious investors who want the widest market access anywhere and the lowest costs at scale.
Moomoo is not the wrong answer for everyone. Self-directed investors who want professional-grade data and charting without paying for a terminal. Where it struggles: Anyone who wants a bank-like relationship or advice, or who finds a dense data interface off-putting.
The honest framing is that these two are not interchangeable. Moomoo gives you Real stocks + options with access to US, HK, SG, AU, while Interactive Brokers gives you Real stocks (global) across 150+ markets, 33 countries. If you already know which markets you want to hold, that single line decides it faster than any score.
What each one really costs
On the headline number, Moomoo charges $0 US stocks and Interactive Brokers charges from $0 (IBKR lite). That is the figure both of them advertise, and it is the least useful one for predicting what you will pay.
Where Interactive Brokers actually charges you:
- IBKR Lite: $0 commission on US stocks and ETFs. IBKR Pro: tiered pricing from a very low per-share rate.
- Currency conversion at close to interbank rates, which is far cheaper than the retail apps and matters if you buy foreign shares.
- Market data subscriptions are charged separately, an unfamiliar concept if you have come from a free app.
- No inactivity fee on most account types since 2021.
Where Moomoo actually charges you:
- $0 commission on US stocks and ETFs.
- Options carry a per-contract fee, low by industry standards.
- Level 2 data included rather than charged separately, which most brokers do not offer.
- Currency conversion applies when funding from a non-USD account.
For a portfolio under a few thousand, currency conversion and withdrawal fees will almost always cost you more over a year than the commission difference. Work out how you will fund the account and how often you expect to take money out, then compare on that rather than on the per-trade rate.
Is your money safe with either?
Moomoo is regulated by SEC, FINRA, MAS, ASIC. Interactive Brokers is regulated by SEC, FINRA, FCA, +. Both are covered by real regulators, so the question is not whether one is legitimate, but which entity your particular account sits under, because that decides your compensation scheme.
Regulated by the SEC and FINRA in the US, the FCA in the UK and multiple other authorities. US accounts carry SIPC protection to $500,000, including $250,000 for cash; UK accounts fall under FSCS to £85,000. IBKR is publicly listed and holds capital far in excess of requirements.
Regulated by the SEC and FINRA in the US, with MAS oversight in Singapore and ASIC in Australia. US accounts carry SIPC protection to $500,000. The parent, Futu Holdings, is listed on Nasdaq.
Worth being clear about what that protection is: compensation schemes cover the broker failing and being unable to return your assets. They do not cover your investments losing value. Nothing here removes market risk.
