Robinhood's August Data: The Froth Cooled, the Core Compounded

Robinhood sits roughly a quarter below its 52-week high and is essentially flat for the year, after a 2025 that minted most of its shareholder returns. On September 10 the company handed out its monthly operating scorecard for August — the kind of report that either shuts a growth narrative down or keeps it alive. At first glance it reads like pure momentum: record platform assets, equities notional volume up 68% year over year, options contracts up 50%. Look a layer deeper and the interesting part is which lines accelerated and which went quiet.

The August report splits its trading volume into two very different buckets, and that split is the whole story. On one side, the frothy repeatable stuff cooled. Crypto notional volume fell 38% year over year to $17.5 billion, even after a 61% rebound from a weak July, and prediction-market event contracts dropped 23% month over month to 4.7 billion despite being up roughly 15x from a thin base a year earlier. These are the businesses that dominated the early-2026 narrative, and they are the ones decelerating.

On the other side, the compounding core just kept layering on. Equities notional volume hit $335.4 billion, up 68% year over year. Options reached 292.5 million contracts, up 50%. Total platform assets rose 26% year over year to roughly $384 billion, and margin balances — the clean revenue driver for a lending business — jumped 72% year over year to $21.5 billion. Add in funded customers at 28.6 million, up about 1.9 million from a year ago, and the base keeps growing even with net deposits easing to $4.0 billion from July's $5.6 billion.

That is the argument for staying, and it is not a momentum argument at all. When a retail brokerage's spike-y, marginal volumes soften, its asset, account, and lending lines are exactly the numbers you want holding up — they are the recurring base that turns volume into durable revenue. Robinhood ended August with a 95% gross margin, a 46% operating margin, and revenue up 38% year over year. The engine is not leaning on crypto; it is deepening the equity and lending franchise that compound quarter after quarter.

But that reading has a price, and the price is the discipline part. Robinhood trades for roughly 20x trailing sales and about 49x trailing earnings, with the forward multiple even higher near 70x because near-term earnings estimates are running below the past year's spike. Set that against the peer set: Interactive Brokers, itself a high-multiple compounder, sells for about 23x sales, while Coinbase trades near 7.5x sales. Robinhood's premium is real, and it assumes the compounding — clients, assets, margin balances, equity and options volume — keeps printing at something like the August pace.

In factor terms this is a strong-but-priced name: A-grade growth and profitability paired with a valuation that leaves no room for the engine to stall. For a watcher deciding whether the August numbers deserve a spot, the honest conclusion is that the report lowers the risk of holding a proven grower — the froth is cooling, but the core is intact. It does not make the stock cheap, and it does not remove the requirement that the core keep compounding to justify the multiple. The trigger that would change the call is the same set of numbers, one month from now: if equity and options volume stop growing off this base, or asset and margin balances flatten, the reason to stay evaporates with the growth that is currently paying for thirty times sales.
