Interactive Brokers Review 2026: The Pro Broker's Moat
IBKR closed at $81.71 on April 17, an all-time high. That is +29% from mid-February and +80% year-over-year — the stock is telling you what the business has been telling us in the monthly metrics: Interactive Brokers is scaling faster than the zero-commission pioneers it was supposed to be left behind by. March 2026's update pinned client accounts at 4.754 million and client equity at $789.4 billion. Q1 2026 earnings land April 21, with consensus at $0.57 EPS and $1.685 billion in revenue. The pitch has not changed since we first reviewed it in February: two pricing tiers, one for casual investors (IBKR Lite, $0 US stock commissions) and one for serious traders (IBKR Pro, sub-penny per-share pricing and the industry's lowest margin rates). You get access to 170 markets across 40 countries from one account. Nobody else offers that. What has changed is the macro backdrop. The Fed's March cut dragged benchmark rates down to 3.64%, which shifted every IBKR rate by the same amount — cash yield stepped down, margin rates stepped down. IBKR also went live with ForecastEx prediction markets in Q1, adding a genuinely new asset class to the platform. The catch is still the same: dense platforms, layered fees, international data that costs extra. Whether this broker is right for you turns on what kind of investor you actually are — not what kind you aspire to be.
