DraftKings (NASDAQ: DKNG) is enhancing DKeX, its internal prediction market exchange, with data showing increased volume during the 2026 football season.

Data from Eilers & Krejcik Gaming’s (EKG) PMI Databook reveals that during the week ending Sept. 7, or Week 1 of the 2026 college football season, trading on DKeX surged almost 610%, the largest rise among key prediction market operators.

The fact that DKeX is matching volume levels of Crypto.com’s Nadex is noteworthy as Nadex clears trades for multiple prediction markets. While total volume on DKeX, Nadex, and Novig is currently modest compared to larger exchanges, trading on these platforms is rapidly growing.

DKeX Combo Volume Surging

With the NFL and college football seasons underway, demand for prediction market combos, or parlays, is expected to increase in the coming weeks.

DraftKings, which recently introduced combos, is already benefiting by processing more multi-leg contract volume through DKeX.

“Combos represented around 46% of total DKeX volume in the first week of September,” notes Allen. “DraftKings is also sending combo flow to DKeX, with combo contract volume up 826% to over 100 million.”

The rapid growth in combo contract volume on DKeX now places it third among major prediction market operators.

Significance of DKeX Growth

The rapid growth of DKeX volume is crucial on several fronts, including DraftKings’ prediction market investments. The platform, launched in June, is already showing strength in capturing sports event contract activity, aided by the World Cup and football season.

The growth of DKeX is also important for DraftKings investors as it validates the company’s vertical integration strategy in predictions and the value of the Railbird Technologies acquisition made last October.

By acquiring Railbird, DraftKings gained exchange technology allowing it to reduce reliance on third-party exchanges.
