DKeX reaches $1 billion weekly volume as Robins plays both sides

Jason Robins walked into the NEXTPredict Summit in New York on Thursday having already made his bet — just not the one most prediction market operators have made.

DKeX, DraftKings' in-house exchange, cleared $1.04 billion in notional trading volume in the week ending October 18. That gave it roughly three and a half percent of the US market, up from two and a third percent at the end of September. Aldrin Research puts it third in the country. Robins told the room it was "the clear number three," and the data supports him.

The more interesting number is the one he didn't mention: eighteen. That's how many states DraftKings can offer its full sports event contract suite, compared to the thirty-eight where it has some form of presence. The gap exists because Robins made a decision no purely prediction-market native operator had to make — stay out of sports contracts in any state where DraftKings already holds a sports betting license. Colorado, New York, Pennsylvania: financial contracts only. The logic is straightforward. Regulators in those states have existing leverage over the company, and Robins decided that leverage was worth more than the incremental revenue from offering a Mahomes touchdown prop on a separate tab.

He called it a "win-win." I'd call it a hedge with a real cost attached, which is a different thing from a free option.

Here's where I part with the consensus reading of DKeX's trajectory. Most of the commentary following the Summit treated the third-place position as proof that DraftKings' cautious, bifurcated model is working. I don't think the volume numbers say that yet. Kalshi holds first clearly, Polymarket a distant second, and DKeX's $1 billion week accounts for a fraction of what the top two clear. The growth rate is real — going from 2.33% to 3.57% share in less than a month is not nothing — but the state restriction isn't a temporary inconvenience that resolves once the Supreme Court rules. Even in the most permissive outcome imaginable, a regulator in New York or Pennsylvania retains the ability to tell a licensed sportsbook that operating a parallel event contract exchange on the same application is inconsistent with its license. Robins knows this. He said it himself: the alternative was licenses under threat.

What Robins has actually built is a product that scales comfortably so long as the legal landscape stays ambiguous, and stops scaling sharply the moment it clarifies in ways that force a choice. If the Supreme Court eventually validates federal preemption for CFTC-regulated exchanges, the pure-play operators — those with no legacy state licensing to protect — gain the most. DraftKings would benefit, but it would benefit less, because it wrote its own restrictions into the architecture of the business before anyone asked it to.
