Legacy sportsbooks chase prediction markets as volumes surge
Legacy sportsbooks are moving into prediction markets as trading volumes in the category have accelerated sharply, with DraftKings reporting a $3.1 billion annualized run rate for its Predictions business after launching in December 2025[1]. The shift matters because the fastest-growing event-contract platforms are now competing directly for consumer wagering flow at a time when traditional sportsbook handle has shown signs of stagnation in some analyses[2][8].
At a Glance
- DraftKings said its Predictions business reached a $3.1 billion annualized trading run rate, indicating rapid early adoption for a new product line[1].
- May 2026 annualized consumer volume in DraftKings’ Predictions offering rose 24% month over month to $1.3 billion, showing momentum into late spring[1].
- U.S. sports prediction markets reached an estimated $2 billion in monthly handle-equivalent trading volume in March, underscoring the category’s growing scale[2].
- Pew Research cited in CryptoSlate reported combined monthly global trading volume on Kalshi and Polymarket rose from less than $5 billion in September 2025 to about $24 billion in April 2026[3].
- Citizens research cited by Covers said prediction market growth has coincided with about a 5% decline in legal sportsbooks’ betting handle, suggesting some cannibalization risk[8].
- The key uncertainty is whether liquidity will consolidate around a few platforms or remain split across sportsbook apps, prediction markets, and regulated exchanges[1][3][7].

DraftKings pushes deeper into prediction markets
DraftKings’ latest filing shows the company’s Predictions business is scaling faster than many market participants expected. The company reported that May 2026 annualized consumer volume rose to $1.3 billion and total annualized volume traded climbed to $3.1 billion, suggesting early product-market fit in a category still working through regulatory and competitive constraints[1].
The move is significant because it places one of the largest U.S. sportsbooks directly inside a market that has been growing beyond election trading and into sports-linked contracts[1][3]. Market participants view this as a competitive response to where incremental wagering activity is migrating, rather than a standalone growth experiment[1][8].
Prediction markets are taking share from traditional betting flows
The scale gap is getting harder to ignore. CryptoSlate reported that U.S. sports prediction markets reached about $2 billion in monthly handle-equivalent trading volume in March[2]. In a separate report, CryptoSlate said Pew Research found combined monthly global trading volume on Kalshi and Polymarket climbed to about $24 billion in April 2026 from less than $5 billion seven months earlier[3].
That growth has attracted legacy operators looking to defend customer attention and wallet share. DraftKings and FanDuel have both moved into event-contract products, and the National Hockey League has already signed licensing agreements with Kalshi and Polymarket, a sign that mainstream sports branding is starting to intersect with prediction markets[4][6]. Analysts note that the licensing step could improve legitimacy for the products, even as it sharpens competition with sportsbooks[4].
| Metric | Reported figure | Source | What it implies |
|---|---|---|---|
| DraftKings Predictions annualized volume | $3.1 billion | [1] | Early traction for a new sportsbook-adjacent product |
| DraftKings Predictions May consumer volume | $1.3 billion | [1] | Growth remained strong into May 2026 |
| U.S. sports prediction market monthly volume | $2 billion | [2] | Category scale is now material |
| Kalshi + Polymarket monthly global volume | $24 billion | [3] | Liquidity has expanded quickly over seven months |
Traditional handle is under pressure, but the degree is disputed
The impact on legacy sportsbooks is not settled. A Citizens analyst cited by Covers said prediction markets have coincided with a 5% decline in legal sportsbooks’ betting handle, while also arguing the cannibalization impact remains relatively modest[8]. That view conflicts with more aggressive industry framing that treats prediction markets as an existential threat, especially as more brands and platforms enter the space[6][10].
Interpretation based on available data: the more immediate risk is not a single sharp displacement event, but gradual diversion of discretionary betting activity across multiple products[1][3][8]. If that pattern continues, incumbents may face margin pressure even if overall wagering demand keeps rising.
Why the capital migration matters
The capital migration into prediction markets is important for three reasons. First, it shifts trading volume toward products that can price political, sports and macro outcomes in one venue, which may appeal to users who want more flexibility than standard sportsbook bet types[3][6]. Second, it gives incumbents a reason to expand into event contracts before customer behavior becomes more entrenched elsewhere[1][6]. Third, it increases regulatory complexity, because prediction markets still face unresolved questions over whether contracts are trading instruments or gambling products[3][7].
That uncertainty remains a real downside scenario. Regulatory disputes could limit distribution, slow product rollout, or force platforms to operate through narrower frameworks than the market now assumes[3][7]. Liquidity concentration is another risk: if activity remains fragmented across a handful of operators, the market may not scale as smoothly as recent volume figures suggest[1][3].
Legacy sportsbooks’ response may not be enough on its own
The current wave of launches suggests incumbents are trying to meet users where the flow is moving, not where the old product stack once sat[1][4][6]. But the data also shows how quickly this market can grow before rules, venue access and consumer habit fully stabilize[3][7].
For now, the clearest signal is that prediction markets have moved from niche curiosity to a meaningful source of trading volume, and legacy sportsbooks are adjusting in real time to avoid losing more of the addressable market[1][3][8]. How much of that flow sticks will depend on regulation, liquidity depth and whether the newer platforms can keep customer activity concentrated as competition intensifies.
