It launched June 26, 2026, runs on the technology and license from DraftKings’ acquisition of Railbird Technologies, and is built directly into the DraftKings: Sports & Casino app. It replaces the third-party infrastructure DraftKings previously used to power DraftKings Predictions, giving the company control over the contracts it lists, the economics of each trade, and how fast it can launch new markets.

What Is DKeX?

Key facts

What it is: DraftKings’ proprietary prediction markets exchange platform, branded DKeX
Launched: June 26, 2026, inside the DraftKings: Sports & Casino app
Built on: Technology and the CFTC license from the Railbird Technologies acquisition (October 2025)
Scale: roughly $3.4 billion annualized consumer volume and $11.3 billion annualized total trading volume (week ending June 21, 2026)
Availability: sports event contracts in 18 states; DraftKings Sports available nationally
Why it matters: prediction markets fall under federal CFTC rules, so DKeX can reach states where the DraftKings Sportsbook is not legal

DraftKings spent the last year doing big numbers in prediction markets on technology it didn’t entirely own. Last week it fixed that.

On June 26, the company launched DKeX, its proprietary prediction markets exchange, and integrated it directly into the unified DraftKings: Sports & Casino app. The plumbing is new. The product on the surface looks familiar. And the strategic shift underneath is the part worth understanding if you bet, trade contracts, or just want to know where this industry is heading.

How is DKeX different from DraftKings Predictions?

Prediction markets let you trade yes-or-no contracts on outcomes. Will a team win, will a player hit a home run, who lifts the World Cup. They settle like a derivative rather than a traditional bet, which is a distinction that turns out to matter a lot.

Here is how to keep the two names straight. DraftKings Predictions is the product you tap and trade on. DKeX is the exchange that runs underneath it. Before DKeX, DraftKings offered these markets but leaned on outside infrastructure to run them. With DKeX, DraftKings owns the exchange itself. The technology and the all-important Commodity Futures Trading Commission license both come from its acquisition of Railbird Technologies, a CFTC-regulated exchange it bought last October.

CEO and co-founder Jason Robins framed it around control. “DKeX provides a vertically integrated foundation for DraftKings Predictions, strengthening our prediction markets content and capabilities, giving us greater control over the technology that powers those offerings, and enabling us to move faster,” he said in the announcement.

Strip out the corporate phrasing and there are three things DraftKings now owns that it didn’t before: the contracts it can list, the economics of every trade, and the speed at which it can build. When you rent your exchange, a third party takes a cut and sets the pace. When you own it, you keep the margin and you ship on your own clock.

How big is DraftKings Predictions? The numbers behind DKeX

DraftKings didn’t build its own exchange on a hunch. The volume already justifies it.

For the week ending June 21, DraftKings Predictions hit roughly $3.4 billion in annualized consumer volume and about $11.3 billion in annualized total trading volume. Combinations, the feature that lets traders bundle multiple contracts into a single position the way a parlay stacks legs, launched in mid-May and has already been used by more than 30% of customers. Analysts have estimated DraftKings could pull in more than $500 million in prediction-market revenue next year across the exchange, brokerage, and market-making.

Then there is the World Cup. The 2026 tournament is shaping up as one of the largest traffic events prediction markets have ever seen, with some analysts projecting it could add $5 billion to $10 billion in trading volume across the sector. DraftKings is launching its own exchange during the biggest sports event on the calendar. The timing is not a coincidence.

Why does DraftKings want a CFTC-regulated exchange?

This is the part that should matter most to bettors, and it has nothing to do with app design.

DraftKings Sportsbook operates under state gaming regulators and is live in 30 states. Prediction markets operate under the CFTC, a federal regulator. That single difference is why a platform like Kalshi can take sports-related contracts in California and Texas, two enormous markets where conventional sportsbooks legally cannot. Event contracts are, for now, the only path into those states.

So DKeX is not just a margin play. It is how DraftKings reaches the roughly 20 states where its sportsbook can’t follow. The company says sports event contracts are now available in 18 states, with the broader DraftKings Sports experience available nationally. Owning the exchange lets it expand that contract menu fast, without waiting on anyone else’s roadmap.

DKeX vs. Kalshi, Polymarket, and FanDuel

DraftKings is not wandering into an empty field. Kalshi has been the runaway leader, with monthly trading volume reported around $17.9 billion in May and roughly 57% of the market, and sports already make up the overwhelming majority of its activity. Polymarket’s U.S. arm, Robinhood, FanDuel Predicts, and Fanatics Markets are all chasing the same space.

DraftKings’ edge is the thing it has spent a decade building: millions of existing sports customers and one app that now holds the sportsbook, casino, and the exchange in the same place. Most prediction-market rivals have to win an audience from scratch. DraftKings is trying to convert one it already owns. By putting DKeX inside the flagship app rather than spinning up a separate product, it is betting that bundling beats building a new front door.

What DKeX means for bettors

For traders, the early questions are practical. Does owning the exchange mean tighter pricing and faster payouts, or just better margins for DraftKings? Does the contract menu actually widen now that DraftKings controls the listings? The company has leaned on its Responsible Trading Center and new My Budget and Controls tools to signal it takes consumer protection seriously, which is a smart move given that regulators and several states are already scrutinizing whether sports event contracts are derivatives or gambling wearing a costume.

That fight over what these markets really are is not settled, and it could reshape the whole category. But the strategic logic of DKeX is clean. DraftKings saw billions in volume flowing through rails it didn’t own, bought the rails, and wired them into the app where its customers already live. The World Cup will show how much that volume is worth. Owning the exchange is what decides how much of it DraftKings actually keeps.

Frequently asked questions

What is DKeX? DKeX is DraftKings’ proprietary, CFTC-regulated prediction markets exchange. It launched on June 26, 2026, and powers the DraftKings Predictions product inside the DraftKings: Sports & Casino app.

How is DKeX different from DraftKings Predictions? DraftKings Predictions is the consumer product you trade on. DKeX is the exchange underneath it. Before DKeX, that exchange layer ran on third-party technology. Now DraftKings owns it, through its acquisition of Railbird Technologies.

How does DraftKings Predictions work? You buy and sell yes-or-no contracts on sports outcomes inside the DraftKings: Sports & Casino app. Each contract settles based on what actually happens, the way a futures contract settles, rather than paying out at fixed sportsbook odds.

Can you parlay on DraftKings Predictions? Sort of, and this is the feature to know. DraftKings calls them combos, and they let you bundle several contracts into a single position, the same idea as a parlay. More than 30% of customers have used combos since they launched in May.

Where is DraftKings Predictions legal? DraftKings offers sports event contracts in 18 states, with the broader DraftKings Sports experience available nationally. Because prediction markets are regulated federally by the CFTC rather than by state gaming commissions, they can be offered in some states where the DraftKings Sportsbook cannot. DraftKings did not publish the full state list in its launch release, so the most reliable check is the in-app availability for your location.

Is DKeX the same as Kalshi? No. Kalshi is a separate CFTC-regulated exchange and the current market leader. DKeX is DraftKings’ competing exchange. The difference is that DraftKings can plug it into an app that already has millions of sports customers.

When did DKeX launch? DraftKings announced and launched DKeX on June 26, 2026.
