Interactive Brokers was founded by Thomas Peterffy in 1978 and is headquartered in Greenwich, Connecticut. It began as a market maker and built one of the first fully electronic trading systems. Today it serves clients in most countries through regulated entities in the US, Ireland, the UK, Canada, Hong Kong, Australia, Singapore and elsewhere.

Its appeal is simple. Few brokers combine costs this low with access this broad, and many clients describe it as the account they would never move away from. The trade-offs are also clear. The account application is long, the range of platforms takes time to learn and customer support is the weakest part of the service. Investors who are willing to spend a few hours getting set up are rewarded with a broker that works for a first ETF purchase as well as for complex options strategies.
Simplified summary for IBKR Pro. See the Interactive Brokers pricing page for current rates in your region. As of Sep 2026.
Interactive Brokers offers two plans. IBKR Pro charges $0.005 per US share with a $1 minimum and sends orders through its SMART routing system, which searches several venues for the best price. IBKR Lite removes the commission on US stocks and ETFs but is available only in the US and Singapore, earns lower interest and charges more on margin. For most investors with a portfolio above $10,000, Pro is the better choice.
In practice, an investor buying $500 of a US ETF each month pays about $1 per purchase. The per order minimum means very small orders are relatively expensive, and European ETFs on Xetra start at €3 per trade. Pro clients can choose between fixed and tiered pricing. Tiered pricing is usually cheaper for frequent traders, but it passes on exchange fees and takes some effort to set up correctly.
Market data is a common source of confusion for new clients. Delayed quotes are free, while real-time data for some exchanges requires a monthly subscription. Long-term investors rarely need it. The first withdrawal each month is free, and there are no account or inactivity fees.
Interactive Brokers is one of the most heavily supervised brokers in the world. It is listed on Nasdaq, included in the S&P 500 and publishes audited financial results. Client assets are held separately from company funds. Your level of protection depends on the entity that holds your account: SIPC cover of up to $500,000 in the US, up to £85,000 under the FSCS in the UK, up to €20,000 under the Irish scheme for EU clients and up to CA$1,000,000 through CIPF in Canada. The company paid a $38 million fine in 2020 over anti-money laundering controls. There have been no failures affecting client assets.
One point deserves attention. IBKR applies margin requirements strictly and in real time. If an account falls below its maintenance margin, positions can be closed automatically without a margin call, sometimes at prices clients dispute. A few traders also report conservative valuations of illiquid option spreads during volatile periods. Anyone using margin should keep a comfortable buffer above the requirement.
The application is fully online but more detailed than at most brokers. It asks about employment, income, net worth and trading experience for each asset class. Plan for 20 to 30 minutes, followed by a manual review that usually takes one or two business days. There is no minimum deposit, and a margin account requires $2,000. Individual, joint, retirement, trust and several business account types are available. The GlobalTrader app offers a shorter route for investors who only want stocks and ETFs.
Trading permissions are linked to the experience and finances you declare. Options or futures can be refused if your answers do not meet the requirements, and permissions added later can take time to approve. It is worth requesting the permissions you expect to need during the initial application and keeping your financial details up to date. Clients whose account value exceeds their declared liquid assets have reported temporary restrictions until the information was corrected.
You can fund the account by bank transfer or wire in more than 20 currencies. SEPA transfers typically arrive in one to three business days, and the Wise integration is faster. PayPal and instant deposits are not available, and debit card funding is limited to US clients. The first withdrawal each month is free.
Deposits can feel slow at first, especially compared with app based brokers. Large withdrawals may also be held for additional review. One long-standing client waited eight days for a large transfer to clear before a property purchase. If you need money on a fixed date, request the withdrawal well in advance.
Interactive Brokers offers several platforms. IBKR Desktop is the modern flagship for Windows, Mac and Linux and is the best starting point for most investors. Trader Workstation, known as TWS, is the professional platform, with algorithmic orders, a large set of order types, API access and a paper trading account. On mobile, GlobalTrader is designed for simple investing and IBKR Mobile gives access to every product. Client Portal covers trading and account management in a browser.
The interface divides opinion. Many new clients find it overwhelming for the first few weeks, while long-term users often say they came to value its practical, no-frills design once they learned it. TWS can be customised to an extraordinary degree, and the API is widely used for automated trading, although the web API requires running a gateway on your own computer. The advanced charts are based on TradingView but offer fewer features, so active chart users often keep a separate charting tool. Login uses the IB Key app, and a standard authenticator app can be added once IB Key is set up.
No other retail broker offers broader access. Clients can trade stocks on more than 90 markets, more than 13,000 ETFs, options on around 30 exchanges, futures, bonds, mutual funds, forex and spot crypto in selected regions. Fractional shares are available from $1, and cash can be held in 27 base currencies.
This range is the main reason many investors outside the US choose IBKR. It makes it straightforward to hold shares from several countries and convert currencies at close to interbank rates. Experienced investors often combine it with a simpler app for everyday use, but for international investing it has few real alternatives.
Uninvested cash earns interest in more than 20 currencies. The website advertises up to 3.38% on USD balances. Rates on IBKR Pro are about one percentage point higher than on Lite. No interest is paid on the first $10,000, and the full rate applies only to balances above $100,000, with a blended rate in between. Smaller accounts therefore earn little or nothing on their cash.
Support is available by phone, through tickets in the Client Portal and through a chatbot. It is the most common complaint about the broker. Simple questions are often answered within hours, but complex cases can take days or weeks, the chatbot can make it hard to reach a person, and specialist areas such as estates and the API are frequently criticised.
The picture is more positive among self-sufficient clients. Many who have used IBKR for ten or twenty years say they have contacted support only a handful of times, and that issues were resolved through tickets. Most routine tasks, from statements to tax documents and transfers, can be handled in the Client Portal without contacting anyone.
Research is strong and largely free. Clients get news from Reuters and Dow Jones, a powerful stock screener, options analysis tools and GlobalAnalyst, which compares company valuations across regions. IBKR Campus and Traders' Academy offer structured courses from basic investing to advanced options and bond strategies.
Interactive Brokers has also added a growing set of AI features. Ask IBKR answers questions about your own portfolio in plain language, AI Screeners build stock screens from a written description, and clients can connect AI assistants such as ChatGPT and Claude to their account through the Model Context Protocol. Several of these tools are still being rolled out and availability varies by region.
Interactive Brokers is the most complete broker available to retail investors. Its costs, market access and financial strength are difficult to match, and its platforms work well for a first ETF purchase as well as for professional strategies. The price is a demanding setup and support that can be slow when you need it. For investors willing to learn the platform, it is the account we recommend most often.
