Robinhood Event Contract Volume Fell 23% in August to 4.7 Billion, Still Up 15x Year Over Year

Robinhood Markets reported that customers traded 4.7 billion event contracts in August 2026, down 23% from the 6.1 billion traded in July but up roughly 15-fold from the 0.3 billion traded in August 2025, according to the company’s monthly operating data release published September 10.

The figures provide a monthly snapshot of the scale of Robinhood’s prediction-markets business, which the company reports as “Event Contracts Traded.” Average daily volume in event contracts was 152 million contracts in August, down 23% from 197 million in July and up about 14 times from 10 million a year earlier. Because Robinhood’s release lists 31 trading days for crypto and prediction markets in both July and August — those products trade every day, unlike equities and options, which had 21 trading days in August versus 22 in July — the month-over-month percentage declines in total volume and daily volume are identical.

Event contracts in the context of a year of growth

The year-over-year comparison shows how quickly the product line has grown: from 0.3 billion contracts in August 2025 to 4.7 billion in August 2026. Robinhood does not break out event-contract revenue in the monthly release, and the data are unaudited and preliminary, subject to completion of the company’s financial closing procedures.

For comparison across Robinhood’s other trading businesses in August: equity notional volume was $335 billion, up 1% from July and up 68% year over year; options volume was 293 million contracts, down 10% month over month and up 50% year over year; and crypto notional volume was $17.5 billion, up 61% from July but down 38% from a year earlier. The crypto figure splits between $7.4 billion in the Robinhood App and $10.1 billion at Bitstamp. The release also notes that Robinhood Chain volumes are not included in crypto trading volumes, and that sequencer revenue from the chain is shared with launch partners under a tiered arrangement in which Robinhood retains 50% of sequencer revenue up to a total of approximately $50 million, 70% up to a cumulative $150 million, and 85% of amounts above that.

Customer and asset metrics

Funded Customers reached 28.6 million at the end of August, up approximately 120,000 from the end of July and up approximately 1.9 million year over year. Total Platform Assets were $384 billion, up 8% from July and up 26% year over year, while Net Deposits were $4.0 billion in the month — a 14% annualized growth rate relative to July Total Platform Assets. Over the trailing twelve months, Net Deposits totaled $74.1 billion, an annual growth rate of 24% relative to August 2025 Total Platform Assets.

A footnote in the release flags a comparability caveat: starting in July 2026, Total Platform Assets include Trump Account assets custodied by Robinhood and Net Deposits include Trump Account contributions, while Funded Customers do not include Trump Accounts. Net Deposits also now include results from Bitstamp (since June 2025), TradePMR (since March 2026) and WonderFi (since June 2026).

On the interest-earning side, margin balances ended August at $21.5 billion, up 4% from July and up 72% year over year. Cash and deposit balances were $19.6 billion, up 1% from July and up 37% year over year, and cash sweep balances were $31.2 billion, up 7% from July but down 9% from a year earlier. A separate footnote explains that in February 2026 Robinhood updated its brokerage High-Yield Cash program to fund growth in margin lending, moving more than $6 billion of cash sweep balances into free credit balances, where the first $10,000 in enrolled balances per eligible customer continues to earn the same interest rate. Total securities lending revenue was $36 million, down 10% from July and down 32% year over year, including negative $8 million in Securities Lending, Net.

Expansion moves ahead of football season and midterms

The August data landed two days after a separate development in Robinhood’s prediction-markets push. Reuters reported on September 8 that Robinhood said it would begin routing selected football event contracts through OG.com’s exchange that same day, adding a trading venue alongside its existing partners ahead of the U.S. professional football season. According to Reuters, Robinhood also said it is taking equity stakes in OG.com and its former parent Crypto.com, and is expanding its election-related contracts ahead of the November midterms with a dedicated hub for state and federal races, some of which could later be routed to Crypto.com and OG.com.

Those are company-stated actions and plans as reported by Reuters; the financial terms and regulatory characterizations in that report have not been independently confirmed through primary records here. The August volume figures, by contrast, reflect completed trading activity across the platform’s existing prediction-markets infrastructure.

How to read the numbers

Robinhood defines average daily volume as total trading volume in a period divided by the applicable number of trading days. For event contracts, the release’s trading-day table shows prediction markets trading on every calendar day of the month, so the denominator differs from equities and options, which trade only on market days. The company cautions that the release is unaudited, that figures for months in the most recent fiscal quarter are preliminary estimates based on Robinhood’s estimates, and that final results reported in its quarterly and annual SEC filings may differ.

Whether August’s pullback proves temporary will become clearer as football-season contracts — including the newly routed OG.com flow — and the expanded election hub feed into September and fourth-quarter data. For now, the established record is a 23% month-over-month decline sitting on top of a fifteenfold year-over-year increase.
