In less than 72 hours in late March 2026, two bipartisan Senate bills landed that could structurally reshape the US sports betting market. Not by regulating sportsbooks—but by shutting down their fastest-growing competitor: CFTC-regulated sports prediction contracts on platforms like Kalshi and Polymarket.
For licensed sportsbook operators, the instinct may be to treat this as good news and wait. That is the wrong read. The correct read is that a regulatory disruption of this scale—regardless of which direction it resolves—creates a defined migration opportunity. The operators who build the CRM infrastructure to capture it now will win. The ones who wait for the outcome before acting will find that window already closed.
The ThreatTwo Bills, One Target: What the Schiff-Curtis and STOP Acts Actually Say
On March 23, 2026, Senators Schiff (D-CA) and Curtis (R-UT) introduced the “Prediction Markets are Gambling Act.” The bill would amend the Commodity Exchange Act to explicitly prohibit CFTC-registered platforms from offering event contracts tied to sporting events, athletic competitions, and casino-style games. The target is not ambiguous: Kalshi and Polymarket are the primary platforms in scope.
Three days later, on March 26, Senators Merkley and Warren introduced the “STOP Corrupt Bets Act,” a broader bill extending prohibitions to elections, war outcomes, and government actions—and mandating a GAO study specifically examining prediction markets’ effects on children. The STOP Act covers more ground, but sports contracts remain central to both bills.
Both bills arrive at an awkward moment for prediction market regulation. The Trump administration’s new CFTC chair had just done the opposite: rescinding the 2024 proposed rule that would have banned sports prediction contracts outright, and walking back a 2025 advisory urging platform caution. The CFTC was signaling permissiveness. Congress is now signaling the opposite.
Kalshi read the room. Hours after the Schiff-Curtis bill dropped, the company announced insider trading restrictions barring athletes, politicians, and candidates from trading contracts tied to their own events. A reactive self-regulatory move—but one that signals the industry understands this legislative threat is substantive, not performative.
The legislative picture is not “one bill might pass.” It is a sustained, multi-front legal campaign at both state and federal levels, with bipartisan sponsorship now on record. Operators who dismiss this as noise are misreading the signal.
Scale of DisruptionHow Big Is the Market the Bills Are Trying to Shut Down
To understand the stakes, start with the volume numbers. Prediction market monthly transaction volume grew from $1.2 billion in early 2025 to over $21 billion in January 2026—roughly 17x growth in under 12 months, with 800,000+ unique wallets active monthly (TRM Labs, 2026). This is not a niche experiment. It is a market that has scaled faster than any major betting product in recent US history.
Kalshi is the primary beneficiary. Its Super Bowl 2026 single-day trading volume surpassed $1 billion—a 2,700% year-over-year increase—with the 30-day Super Bowl run generating $10.3 billion in total notional volume (CNBC, Feb 2026). March Madness 2026 pushed further: $3.4 billion in a single record week, generating over $25 million in fees in the first four days of the NCAA tournament alone—nearly doubling the entire three-week volume from the 2025 tournament season (DeFiRate, March 2026).
With 91.1% of Kalshi’s total notional volume concentrated in sports contracts (Sacra), a ban on sports prediction contracts is not a regulatory setback for Kalshi—it is an existential business event. At an annualized sports revenue run rate of approximately $1.3 billion in 2026 (up from ~$260M in 2025 and ~$24M in 2024), and a $22 billion VC valuation, the stakes are not abstract.
Kalshi’s user growth trajectory compounds the picture. Monthly active users grew from 600,000 in January 2025 to 5.1 million by early 2026—roughly 8.5x in 13 months. The app logged 6.3 million downloads between September 2025 and February 2026. Over the same period, DraftKings downloads fell 18% and FanDuel downloads fell 13% (Sacra). Prediction markets are not just growing—they appear to be growing at the direct expense of traditional sportsbook acquisition.
Prediction Markets Are Intercepting the Next Generation of Bettors
The competitive threat to sportsbooks extends beyond volume metrics. It is fundamentally a demographic story—and for operators thinking about 5-year LTV, it is the most important number in this article.
24% of Kalshi users are under 25 (median age 31). By comparison, only 7% of DraftKings and FanDuel users are under 25, with both platforms averaging a median user age of approximately 35 (Sacra). Prediction markets are not stealing existing sportsbook customers at scale—they are capturing Gen Z bettors before they ever download a legacy sportsbook app. That is a structural acquisition channel loss, not a retention problem.
Fanatics made this explicit. The company positioned its prediction market app as a national acquisition channel specifically for territories where it lacks a sportsbook license. Prediction markets became an alternative onramp to the bettor relationship—a strategy now under direct regulatory threat from both bills.
The major sportsbook operators are not sitting still. DraftKings, FanDuel (Flutter), and Fanatics have all launched their own prediction market products. Flutter is committing $250–$300 million to FanDuel Predicts in 2026. Yet Flutter still missed analyst consensus by approximately $900 million ($18.4B vs. $19.3B projected), citing prediction market headwinds. The investment is happening; the returns are not yet materializing at the pace analysts expected.
If the ban passes, the younger user cohort on Kalshi and Polymarket does not disappear. They become a captive re-engagement opportunity for operators who have the CRM infrastructure to identify and reach them. The operators who have built that capability before the regulatory event will be positioned to act within days. The ones who haven’t will be building it while competitors execute.
Regulatory ScenariosThree Outcomes Operators Must Model—and What Each Means for Your Business
The regulatory path is genuinely uncertain. Courts are split, Congress is active, and the CFTC under the current administration has shown permissive instincts that conflict with legislative direction. Operators need to model all three plausible outcomes, not bet on one.
Scenario A: Full Federal Ban on Sports Prediction Contracts
The Schiff-Curtis bill passes, amending the Commodity Exchange Act to explicitly prohibit sports event contracts on CFTC-registered platforms. Kalshi and Polymarket sports volumes collapse. The 5.1 million Kalshi MAUs with active sports betting behavior suddenly have no regulated prediction market venue for those bets.
For licensed sportsbooks, this is the highest-upside scenario—but only for operators who have prepared. A ban creates a migration surge: millions of users who have been betting on sports outcomes in a prediction market format will look for an alternative. The sportsbook operators with proactive re-engagement funnels already in place, targeted at the prediction market user cohort, will capture that traffic in real time. The ones without that infrastructure will watch the first-mover advantage evaporate within weeks.
Scenario B: State-Level Regulatory Control Replaces Federal Preemption
Federal legislation stalls or fails, but state-level enforcement intensifies. Prediction market operators are required to obtain state gaming licenses, submit to state tax regimes, and comply with state responsible gambling frameworks. The 11 states that have already issued cease and desist orders enforce their orders successfully; additional states follow.
This scenario creates a multi-year transition period rather than a sudden disruption. Prediction market operators either partner with licensed sportsbook infrastructure or pursue state licenses market by market. The competitive landscape becomes hybrid: prediction markets operating where licensed, absent where not. For sportsbook operators, this is a geographic arbitrage opportunity—states where prediction markets cannot operate become higher-value markets for traditional sportsbook acquisition.
The $600 million in annual state sports betting tax revenue currently lost to CFTC-regulated platforms that pay no state gaming taxes is the primary driver of state legislative action. That number is large enough to sustain aggressive state-level enforcement regardless of federal outcome.
Scenario C: Federal Oversight with Tightened CFTC Restrictions
Neither full ban nor state takeover. Instead, the CFTC implements tightened restrictions: volume caps, mandatory age verification, sports-only blackout periods around certain events, enhanced disclosure requirements. Prediction market growth slows but does not reverse. The platforms remain operational under heavier regulatory overhead.
For sportsbook operators, this is the most challenging competitive scenario. Prediction markets continue to exist and grow, just more slowly. The competitive pressure on acquisition and engagement persists. Operators who respond by deepening CRM personalization and content quality—rather than relying on market access advantages that won’t materialize—will retain users who might otherwise migrate.
What Licensed Sportsbooks Should Be Doing Right Now, Not After the Vote
The instinct to wait for regulatory clarity is understandable. It is also strategically costly. By the time a bill passes or a court ruling lands, the first-mover window for capturing migrating users will be measured in days, not months. Here is the playbook for operators who want to be ready.
1. Identify the Prediction Market Cohort in Your Existing User Base
Start with your own database. Users who registered with your sportsbook but sharply reduced their betting frequency after Kalshi and Polymarket launched in 2025 are your highest-value re-engagement segment. They have an existing account with you. They have demonstrated sports betting intent. They migrated, they did not churn permanently. A regulatory ban brings them back—if you have a reason to reach them.
Operators cut acquisition and retention spend by an average of 25% in February 2026 versus February 2025—a retention-first pivot that is the right strategic direction, but only valuable if CRM infrastructure can execute against meaningful segments at scale.
2. Build Event-Driven CRM Triggers Tied to Regulatory Milestones
Bill hearings, state court rulings, and CFTC announcements are not just news events—they are CRM triggers. Each regulatory milestone creates a specific re-engagement window. A committee vote on Schiff-Curtis that advances the bill toward the floor is a signal that a ban is becoming more probable; that is the moment to activate a targeted outreach sequence to users who have prediction market behavioral patterns.
Operators without automated segmentation cannot execute this playbook. By the time a manual CRM team identifies the relevant segment, builds the campaign, and gets approval, the window has passed. The competitive advantage in a regulatory disruption event goes entirely to operators with real-time segmentation and trigger-based campaign execution already in place.
3. Build for the Prediction Market User Profile, Not the Legacy Bettor
Over 30% of Polymarket wallets are now using AI agents for trading (TRM Labs / LayerHub). The prediction market user base is materially more technically sophisticated than the median sportsbook user. Generic promotional emails will not convert them. A “100% welcome bonus” message sent to a user who was running automated trading strategies on Polymarket is not a retention play—it is an unsubscribe trigger.
Content for this cohort needs to mirror the analytical depth they are accustomed to: odds movements, sharp money signals, market efficiency analysis, same-game parlay data. The CRM infrastructure requirement here is not just segmentation—it is content generation at a quality level that this audience will find credible.
| Scenario | Timeline | Primary Operator Action |
|---|---|---|
| Federal ban passes | Migration surge within days | Activate pre-built re-engagement campaigns targeting PM user cohort |
| State-level enforcement wins | Multi-year state-by-state transition | Geographic arbitrage — deepen CRM in states where PMs cannot operate |
| CFTC tightens restrictions | Ongoing competitive pressure | Compete on CRM personalization depth vs. PM market access advantage |
| Status quo persists | Continued PM growth | Build retention infrastructure now before acquisition losses compound |
Key Dates and Legislative Milestones to Watch in 2026
Operators should be tracking specific milestones rather than waiting for a single definitive outcome. Each milestone either accelerates or slows a particular regulatory path—and each carries CRM implications.
- March 23, 2026: Schiff-Curtis “Prediction Markets are Gambling Act” introduced in the Senate. Bipartisan sponsorship (D-CA + R-UT) signals this is not a partisan positioning exercise.
- March 26, 2026: Merkley-Warren “STOP Corrupt Bets Act” introduced. Broader scope (elections, war, government actions) + mandatory GAO study on effects on children.
- Q1–Q2 2026: Minnesota, Hawaii, and Kentucky state ban bills advancing through committee processes. First state-level legislative wins for ban advocates would create enforcement precedent and further accelerate Congressional action.
- Ongoing — federal court calendar: Kalshi’s Nevada injunction appeal and Massachusetts gaming license ruling are the most consequential near-term legal events. A federal ruling on preemption—either affirming or rejecting Kalshi’s position—determines whether state enforcement becomes the de facto regulatory mechanism regardless of federal legislation.
The pace of legislative activity in just the first week of late March 2026—two major bills introduced within 72 hours—suggests this issue has political momentum that will not stall without a court ruling or a CFTC action that definitively settles the preemption question. Operators planning on a 12-month decision horizon should reconsider. The relevant planning horizon is now measured in weeks.
