Why can Robin Hood offer trading without commissions?
All discount brokers offer a commission structure that is based on the average kind of order that their target audience will make. Different brokers advertise to different target audiences. They could all have a lot lower commissions than they do. The maximum commission price for the order ticket is set at $99 by the industry securities regulators. When discount brokers came along and started offering $2 - $9.99 trades, it was simply because these new companies could be competitive in a place where incumbents were overcharging. The same exists with Robinhood. The market landscape and costs have changed over the last decade with regulation NMS, and other brokerage firms never needed to update drastically because they could continue making a lot on commissions with nobody questioning it. The conclusion being that other brokers can also charge a lot less, despite their other overhead costs. Robinhood, like other brokerage firms (and anyone else trading directly with the exchanges), are paid by the exchanges for adding liquidity. Not only are many trades placed with no commission for the broker, they actually earn money for placing the trade. If Robinhood was doing you any favors, they would be paying you. But nobody questions free commissions so they don't. Robinhood, like other brokerage firms, sells your trading data to the highest bidder. This is called "payment for order flow", these subscribers see your order on the internet in route to the exhange, and before your order gets to the exchange, the subscriber sends a different order to the exchange so they either get filled before you do (analogous to front running, but different enough to not be illegal) or they alter the price of the thing you wanted to buy or sell so that you have to get a worse price. These subscribers have faster computers and faster internet access than other market participants, so are able to do this so quickly. They are also burning a lot of venture capital like all startups. You shouldn't place too much faith in the idea they are making [enough] money. They also have plans to earn interest off of balances in a variety of ways and offer more options at a price (like margin accounts).
