Prediction Markets Are No Longer a Side Conversation
Prediction markets are no longer a fringe category sitting outside the main gambling conversation. They are now forcing the industry to rethink what scale, distribution, and market access really look like in U.S. sports-related gaming. The question is no longer whether this category matters. The question is who is actually winning, and why. Recent market analysis tied to Bank of America’s outlook projects that U.S. sports event contracts could eventually reach $1.1 trillion in annual volume, with Kalshi currently holding an estimated 89% share of measured U.S. volume.
Pure-Play Operators Built the Early Lead
At first glance, the answer may seem simple. Pure-play operators like Kalshi and Polymarket have the momentum. They built around prediction markets as a core business, not as an extension of a sportsbook or DFS platform. That matters because product focus tends to win early in emerging sectors. Kalshi, in particular, has benefited from entering the market with a regulatory framework built around event contracts rather than trying to retrofit a sportsbook brand into something new. Polymarket, meanwhile, has built major global recognition and remains the leading pure-play name outside the narrower U.S. sports contract discussion, even if measured U.S. sports share still trails Kalshi materially.
The Chart Shows a Different Kind of Leadership
Still, the chart you shared adds another layer that should not be ignored. On monthly traffic, Polymarket appears to lead the field by a wide margin at 49.9 million, followed by Robinhood at 26.92 million and Coinbase at 19.8 million, while Kalshi sits at 10.8 million. Fanatics, PrizePicks, FanDuel Predicts, Underdog, OG.com, NOVIG, and DraftKings Predictions all trail those top names in traffic terms. That does not automatically mean Polymarket is winning the U.S. sports contract race, but it does suggest that audience attention, brand curiosity, and general platform awareness are distributed differently than pure measured contract share.
In other words, traffic leadership and category leadership are not necessarily the same thing.
This Market Is Splitting Into Several Different Races
That distinction is important because this market is now splitting into multiple races at once. One race is about contract volume. Another is about consumer mindshare. Another is about distribution. And another is about who can turn an existing database into a prediction market customer base faster than everyone else.
On contract share, Kalshi appears to be ahead. On broad traffic and awareness, the chart suggests Polymarket is commanding far more attention. On distribution power, Robinhood may be the most disruptive company in the field because it can place event contracts directly in front of a massive existing financial user base without needing to teach people an entirely new app experience. The source material also describes Robinhood as having emerged as a distributor with reach that pure-play platforms cannot match, integrating Kalshi-powered contracts directly into its ecosystem while building its own exchange infrastructure.
Why Sportsbooks and DFS Operators Have a Real Opportunity
That is where the conversation becomes far more interesting for sportsbooks and DFS operators entering prediction markets.
The advantage for sportsbooks and DFS operators is obvious. They already have customers. They already have app installs. They already have payment familiarity, sports-oriented engagement habits, and large databases built over years. In theory, that should make them extremely dangerous once they decide to participate seriously in prediction markets. DraftKings has already launched DraftKings Predictions through Crypto.com’s CFTC-registered exchange structure, while Flutter has rolled out FanDuel Predicts and committed significant investment to the category. Fanatics has also entered the space across multiple states. These are not experimental names with no market relevance. They are major consumer brands with operating leverage.
Why That Same Position Also Creates Risk
But that same incumbency creates risk.
Sportsbooks and DFS operators are not entering prediction markets with a blank slate. They are entering with legacy positioning, regulatory baggage, internal product conflicts, and consumer expectations tied to traditional betting formats. A pure-play operator like Kalshi does not have to worry about cannibalizing sportsbook hold, confusing customers about whether something is a bet or a contract, or balancing multiple regulatory narratives under one brand. It can stay focused on building the category as its main business.
That focus is a real competitive advantage.
Having a Big Database Is Not Enough
Another issue is that not every database converts equally. A sportsbook database may be large, but size alone does not guarantee migration into prediction markets. The user experience has to feel simple, credible, and worth repeating. If the onboarding flow is clunky, if the product feels like a side tab rather than a core experience, or if the operator treats the category as defensive rather than strategic, then the existing user base becomes less valuable than it looks on paper.
That is why I think the real edge for operators entering this space is not simply having customers. It is having customers in the right states, with the right product access, under the right conditions.
Non-Legal Sports Betting States May Become a Hidden Advantage
One of the more intriguing angles is the opportunity for DFS operators and major sports operators in states where sports betting still is not legal. In those jurisdictions, established brands may already have active user accounts, daily engagement patterns, and permission to market to sports-oriented customers. That creates a meaningful opening.
If prediction markets can be layered onto an existing relationship with relatively low friction, operators with mature DFS-style databases may suddenly have monetization pathways that traditional sportsbook legalization never gave them. That does not mean they are winning today. It means they may have a hidden strategic advantage that becomes far more valuable as the market matures.
Pure-Play Leaders Still Hold the Most Important Early Advantages
At the same time, pure-play leaders still have important strengths that incumbents cannot copy overnight. Kalshi’s 89% share of measured U.S. prediction market volume reflects more than just timing. It reflects focus, regulatory positioning, and a market identity built specifically for this category. Polymarket’s scale in attention and traffic suggests that it has also built something powerful: cultural relevance.
In emerging categories, relevance matters because it influences where users first learn, first explore, and first participate. That kind of top-of-funnel power can become a major asset even if the regulatory path differs by geography and product type.
Traditional Operators Are Also Protecting Older Business Models
There is also a structural reason pure-play leaders have moved faster. They are not trying to protect an older business model. Traditional sportsbooks have to think through margin impact, product hierarchy, customer overlap, and investor messaging. Prediction market leaders do not. They are building directly into the market opportunity that Bank of America sees as potentially enormous. That freedom allows them to iterate faster and market more aggressively around the category itself.
So Who Is Actually Winning?
If the question is who currently leads the U.S. prediction market race on measured sports contract volume, the answer is Kalshi. If the question is who is winning on broad consumer traffic and attention, the chart suggests Polymarket is ahead by a significant margin. If the question is who could become the most powerful distribution force, Robinhood deserves serious consideration. And if the question is which traditional gaming companies may still be underestimated, the answer is likely the sportsbooks and DFS operators with large, established customer databases that can be activated in states where sports betting remains unavailable or restricted.
The Next Chapter Has Not Been Decided Yet
That is why this race should not be viewed as a simple showdown between one winner and everyone else. It is a contest between category specialists, distribution giants, and incumbent operators trying to convert legacy strength into new-market relevance.
For now, the pure-play operators deserve the credit. They saw the opening first, built for it directly, and shaped the public conversation around prediction markets. But the next chapter may belong to whichever sportsbook or DFS operator figures out how to turn its existing database into sustained prediction market participation without adding too much friction or confusing its own value proposition.
That is the real battle ahead. Not who can launch a product first, but who can turn access, trust, and habit into repeat market activity at scale.
