Everyone Thinks Robinhood Sells Your Trades. It Quietly Became a Bank.

Open the Robinhood app, buy a share with no commission, and a familiar accusation follows: you're not the customer, you're the product — your trade gets sold to a market maker, and that's how the free app pays its rent. It's a good story, and for one stretch of the company's life it was even true: in 2020 roughly three-quarters of Robinhood's revenue came from payment for order flow.⁶ But somewhere between then and now, while everyone was still arguing about PFOF, Robinhood quietly turned into a different company. The free-trades startup grew up into something that earns its keep the way a bank does.

The official story is that Robinhood is a payment-for-order-flow machine. By the numbers, that story is years out of date. In 2024 the company earned $1.647 billion from transactions and $1.109 billion from net interest, out of $2.95 billion total.¹ PFOF is no longer the majority of the business — it's one leg of a stool, and not the leg growing fastest.

Three pillars where everyone sees one

Here is the thesis a smart friend could repeat at dinner: Robinhood is no longer a brokerage that sells order flow — it's a deposit-and-lending business wearing a trading app. The revenue now sits on three roughly distinct pillars. Transaction-based revenue, which includes PFOF, was about $1.65 billion in 2024. Net interest revenue — margin loans to traders, the spread on swept cash, securities lending — was about $1.11 billion. And subscriptions and other, led by Robinhood Gold, make up the smaller but rapidly expanding remainder.¹ The first pillar is the one everyone talks about. The second is the one that quietly decides whether the company has a good year.

It's not stock trades. It's options.

Even inside the transaction pillar, the popular picture is wrong. When people say Robinhood gets paid to route your trades, they picture stocks. But equity routing is the runt of the litter. In the third quarter of 2024, options transaction revenue was $202 million — against just $37 million from equities, with crypto adding $61 million.³ The quarter before, options brought in $182 million and equities $40 million.⁴ The reason is structural, not promotional: per the SEC's own research, options PFOF runs roughly twice equity PFOF per order, and crypto PFOF is about forty-five times higher per dollar of trading value than equities.⁶ Lumping all three under one word — 'PFOF' — hides the only number that matters. The stock trade is the loss leader. The contract is the profit.

The quiet engine: getting paid on cash that just sits there

The second pillar is where the bank lives. When interest rates are high, an enormous amount of money simply earns its keep by existing. Robinhood lends to margin traders — its margin book grew 126% in 2024 to $7.9 billion.² It sweeps idle customer cash to partner banks — those balances grew 59% to $26.1 billion — and it pockets the spread between what the banks pay and what it passes back to customers.² None of this requires anyone to place a single trade. It requires only that money be present and rates be elevated. That is why net interest income climbed to nearly $1.1 billion and now sits almost level with all transaction revenue combined.¹ The free trading app discovered the oldest revenue line in finance: be the one holding the float.

Why Robinhood Gold is really a deposit funnel

Robinhood Gold is sold as a trading upgrade — $5 a month or $50 a year for higher margin limits, Level II market data, an IRA match, and a high-yield cash program.⁷ But read it as a financier would. Every Gold feature pulls more money into the two places Robinhood earns interest: it raises margin borrowing and it concentrates cash into the sweep, where Robinhood keeps the spread between the bank rate and the rate it pays subscribers.⁷ The subscription fee is the smallest part of the value Gold creates. The point is the balances it gathers. Gold subscribers went from 2.0 million in mid-2024 to 3.0 million by year-end, and the model's appetite for it is plain — it has been among the most consistently expanding parts of the business.⁴²

It's worth pausing on that order, because it punctures the cheeriest myth of all — that commission-free means costless. The SEC found that in Robinhood's early years, high PFOF rates produced inferior execution prices that, in aggregate, cost customers more than they saved on commissions. Robinhood paid a $65 million penalty without admitting or denying the findings.⁵ 'Free' had a price; it was just paid in basis points instead of dollars.

Isn't this just a bull market in disguise?

The honest objection is that none of this is durable — that Robinhood's three pillars all happen to lean the same way at the same time. Options and crypto volume swell when retail is euphoric; net interest swells when rates are high; both conditions held through 2024 and 2025. Revenue rose 58% in 2024 and another 52% in 2025 to $4.5 billion, with net income reaching $1.9 billion.²⁸ That looks less like a diversified business and more like a single bet on a hot market placed three times. There's truth in it. And the 2024 profit deserves an asterisk: the $1.41 billion of net income included a $424 million one-time tax benefit, so the underlying operating result was smaller than the headline figure suggests.¹ But the diversification is real where it counts most — the risk has changed shape. The threat that defined Robinhood's reputation was a PFOF ban. A threat that now shapes its earnings is the opposite of trading-related: a fall in interest rates that drains the net-interest pillar regardless of how much anyone trades. The company spent years being feared for the wrong reason.

Robinhood still sells the trade for free, and the critics are still litigating a business model the company half-outgrew. The slogan stayed the same; the engine swapped underneath it. Today the app makes more on the cash that sits still than on most of the trades that move, and the contract that thrills a day trader pays it far better than the share ever did. The genius wasn't free trading. It was using free trading to gather millions of accounts, and then quietly learning to earn a banker's living off the money inside them.
