ProphetX Wins CFTC DCM and DCO Approval — the Sweepstakes-to-Prediction-Market Conversion Wave Begins
ProphetX, the former state-licensed sportsbook turned sweepstakes exchange, won CFTC approval this week for both a Designated Contract Market and a derivatives clearing organization, and will convert to a sports prediction market early next week. It is the first of an expected wave of sweepstakes operators — Novig and Sporttrade have applications pending — pivoting to federal regulation as states ban sweepstakes apps.
ProphetX won CFTC approval this week for both a Designated Contract Market (DCM) and a derivatives clearing organization (DCO), and told customers it will take the site offline Monday to convert from a sweepstakes exchange into a sports prediction market, with a launch expected early next week. Existing cash balances carry over and customers need to take no action. The dual approval is the detail that matters: holding both a DCM and a DCO license means ProphetX clears its own trades rather than routing through a third party. CEO and co-founder Dean Sisun framed the milestone around that fact, calling ProphetX "the first sports-native direct-clearing prediction market in the United States." The CFTC received the application on October 31, 2025, so the approval ran roughly seven months — fast by the standard of Kalshi's multi-year path to DCM status.
ProphetX is the leading edge of a conversion wave, not a one-off. The company has already been through two identities — state-licensed sportsbook (as Prophet Exchange), then peer-to-peer sweepstakes exchange — and the pivot to a federally regulated prediction market is its third. The driver is regulatory pressure on the sweepstakes model: a growing number of states have banned sweepstakes gaming apps, and a CFTC DCM license offers a federal framework that sidesteps state-by-state sweepstakes prohibitions while still permitting sports markets. Two more former operators are in the queue behind ProphetX: Novig filed its DCM application in late January 2026, and Sporttrade — itself a former state-licensed sportsbook — filed about a week later. The pattern is now clear enough to name: the sweepstakes and small-sportsbook tier is migrating wholesale toward CFTC regulation.
The timing collides with an unsettled federal picture. The CFTC released its proposed prediction-market rules on Wednesday; they hit the Federal Register on Friday, opening a 45-day public comment window, and the proposal supports trading in sports markets. But eight states are simultaneously suing current operators or being sued by the CFTC over whether these contracts are unlicensed sports betting, and members of both the House and Senate have questioned the legality of federally regulated venues listing sports contracts. Mick Mulvaney, the former congressman now running Gambling is Not Investing, put the opposition case bluntly: "The CFTC was created to oversee commodity markets, not to become the nation's sports betting regulator. Congress never intended for federal derivatives law to become a backdoor for unsafe sports gambling." The core question — whether prediction markets can offer sports contracts at all — is widely expected to reach the US Supreme Court, either through one of the state cases or a challenge to the proposed rules once finalized. ProphetX is launching into that uncertainty deliberately.
Our read on why a new entrant makes sense in a market this concentrated. Kalshi dominates — a Bank of America report this year put its US share around 90% — and sports drive the volume, with a late-May Pew Research report finding sporting events make up about 80% of Kalshi's trading. On the surface that looks like a closed market. But prediction markets do not consolidate the way the sportsbook boom of the early 2020s did, and the reason is structural: there is no house edge to defend, so traders gravitate to whichever venue shows the best price, and the existence of multiple venues actively creates arbitrage opportunities that reward fragmentation rather than punishing it. A sports-native exchange that clears its own trades can compete on price and execution without needing Kalshi's scale. ProphetX may never crack the top tier, but "dominant incumbent" is a weaker moat in event contracts than it was in sportsbooks — which is precisely why DraftKings, Fanatics, FanDuel, Novig, Sporttrade, and now ProphetX are all willing to enter anyway.

Missouri AG Sends Cease-and-Desist Letters to Six Prediction Market Operators
Missouri Attorney General Catherine Hanaway issued cease-and-desist letters on September 18 to six prediction market operators — Kalshi, Polymarket, Robinhood, Crypto.com, Novig, and Underdog — alleging their sports event contracts constitute unlicensed sports wagering under Missouri law. The letters give platforms 30 days to comply or obtain licenses from the Missouri Gaming Commission. Missouri is the broadest multi-platform C&D action to date, targeting all major operators simultaneously. The action arrives one day after Montana and Kalshi filed a joint stipulation in which Montana agreed to pause enforcement while Ninth Circuit en banc review is pending.
Yahoo Finance Ends Polymarket Data Partnership After Five Months
Yahoo Finance and Polymarket mutually ended their prediction market data partnership on September 18, approximately five months after the companies announced an exclusive arrangement in November 2025. The Polymarket data hub that Yahoo Finance launched in January-February 2026 was quietly taken down in April 2026. No reason was publicly disclosed. Yahoo Finance retains an advertising relationship with Polymarket. The partnership's end is a setback for Polymarket's strategy of embedding its probability data into mainstream financial media platforms.
Montana and Kalshi Reach Joint Stipulation — State Pauses Enforcement Pending Ninth Circuit En Banc
Kalshi dismissed its lawsuit against the Montana Department of Justice on September 17 after both sides filed a joint stipulation in which Montana agreed to pause all enforcement, investigations, and cease-and-desist proceedings against Kalshi's event contracts. The pause lasts until the Ninth Circuit either denies en banc review of the August 28 ruling or issues an en banc decision. Montana must give Kalshi 30 days written notice before resuming any enforcement action after that window closes. The agreement mirrors the Robinhood-Michigan stipulation from September 4 and reinforces a pattern of states reaching negotiated compliance pauses while the appellate process plays out.
