On May 19, Light & Wonder president and CEO Matt Wilson used a keynote at a Las Vegas gaming conference to say publicly what much of the industry has been saying privately: prediction markets are no longer a curiosity. "It has gone parabolic over the last six months," he told the room. "Kalshi and Polymarket have double the market value of DraftKings and FanDuel. That's amazing and brutal."
His conclusion was a call to collective action:
"The industry needs to get together and work collectively to figure out how to slow this juggernaut down."
We think that is the wrong lesson — at least for operators. Here is why.
A Tier-1 vendor just validated the category
Light & Wonder is one of the largest gaming suppliers in the world. When its CEO says the money flowing into prediction markets "is coming from somewhere" because "it's not like there's an infinite discretionary dollar for the casino," that is not a niche observation. It is a Tier-1 supplier confirming, on stage, that prediction markets compete for the same wallet as casino and sportsbook.
Wilson went further on product convergence: "We know people are working on five-reel slot machines derived off complex contracts." Prediction mechanics are moving toward gaming formats, and gaming spend is moving toward prediction venues. The line between the verticals is dissolving from both sides — which is precisely the premise behind prediction markets as an operator product rather than a separate industry.
"Slowing the juggernaut down" is not an operator strategy
The collective response Wilson describes is already underway. Wisconsin's Department of Justice has sued Kalshi, Polymarket, Robinhood, Coinbase and Crypto.com over what it calls illegal sports betting; the CFTC is in court against New Mexico over federal pre-emption. That fight will take years, and it is a US fight about US law.
For operators — especially outside the US — none of it changes the demand picture. Litigation can slow a competitor's distribution; it cannot un-teach players a bet format they clearly like. When a format doubles the market value of the incumbents inside a few quarters, the demand is real and it will find a venue. The only open question is whose product it flows through.
The same-dollar argument cuts both ways
Wilson's sharpest point is the finite discretionary dollar. If prediction volume comes from the same pool as casino and sportsbook spend, an operator has exactly two options: watch that share of wallet migrate to standalone prediction apps, or give players the format inside the product they already deposit into.
The economics favour the second. Around 70% of prediction bets are sport-aligned, which means event contracts sit naturally next to a sportsbook and feed the same retention loop around live sport — one wallet, one player view, one CRM. We showed the architecture behind that in the Polybetting operator-stack reveal: multi-source liquidity with UI, analytics, risk, reporting and marketing funnels included, not a bare order-book API the operator team has to build around.
What operators can do about prediction markets now
Adding prediction markets to an operator stack does not require waiting for US courts to settle the definition of gambling. Polybetting deploys under licence tracks operators already use, with geofiltering per jurisdiction handled as a compliance requirement, not an afterthought — and it is already live: see the Curaçao Tier-2 operator launch.
Wilson is right about the trajectory: prediction markets are pulling real spend from the same player wallet the rest of the industry lives on. Operators who treat that as a threat will spend the next two years watching the litigation. Operators who treat it as a signal will spend them owning the segment — starting with a look at how a prediction-market launch actually works.
