Robinhood's August event volume ran 64% above its non-World-Cup pace

The segment billed $156 million on 13.6 billion contracts, which is about 1.1 cents each ^[1][2][18]. Both publishers count contracts rather than notional value, so the fee against money at risk cannot be worked out from what they report. At a penny a contract, repeating a tenfold year means moving roughly ten times as many contracts.

Crypto Briefing's quarterly figure makes the August headline less of a jump than it looks: 13.6 billion over three months averages 4.53 billion a month, so August's 4.7 billion sits about 4% above that pace ^[2][6][15]. Take the tournament out and the comparison changes. About 5 billion of the quarter's contracts were tied to the World Cup, per Crypto Briefing, leaving 8.6 billion, or 2.87 billion a month, and August ran about 64% above that ^[11][16]. Three months at August's rate is 14.1 billion contracts, which at 1.1 cents bills around $162 million ^[17]. The same month a year earlier carried about 310 million contracts ^[19].

Tenev made the forecast on CNBC's Mad Money on September 20 ^[20]. "We're already seeing other categories like crypto taking a disproportionate share," he told Jim Cramer, adding that "within a few years, sports will actually be in the minority, similar to active trading at large" ^[21][22]. Sports was the way in: "Sports has been a great tool to bring people in, get liquidity, get interest, establish," he said ^[7].

The seasonality argument cuts against him as easily as for him. Crypto Briefing notes that the NFL season runs September through February, March Madness lasts three weeks, the World Cup comes once every four years, and sports volumes dip between those events ^[14]. August sits in one of those gaps.

Robinhood built the hub on Kalshi, then layered on Rothera, its CFTC-licensed joint venture with Susquehanna, which holds roughly 90% of MIAXdx, the exchange formerly called LedgerX ^[8][13]. On September 8 it took minority stakes in Crypto.com and the prediction-market spinoff OG.com, a deal Crypto Briefing puts at $5 billion following a Citadel Securities investment ^[3]. Decrypt describes the stakes as adding a third partner to clear and settle trades ^[4]. Both publishers report the $156 million as one figure, brokerage and exchange revenue together.

In my view this is a CFTC-regulated derivatives line selling crypto opinion by the penny. The supporting evidence is that event-contract revenue grew more than tenfold in a quarter when Robinhood's crypto trading revenue fell ^[12][5]. Two outcomes would prove that wrong: sports reclaiming the majority of volume once the NFL and March Madness quarters are billed, and revenue per contract sliding below a cent as crypto categories take share. The legislative risk sits in the political category, where lawmakers have filed more than 10 bills since January, including the PREDICT Act, which would bar members of Congress and senior officials from trading contracts tied to political events ^[9].
