Google Adds Prediction Market Ad Policy — CFTC License Required, Ads Blocked in Five States
Google published a dedicated prediction markets section in its advertising policy on October 15, requiring domestic operators to hold a CFTC Designated Contract Market licence to run ads — favouring Kalshi and Polymarket US over unlicensed rivals. Google also bars prediction market ads targeting five states where enforcement is most active: Connecticut, Michigan, New York, Ohio, and Nevada. The policy makes Google's ad platform mirror the state enforcement map, using commercial access as a de facto regulatory layer.
Google updated its advertising policy on October 15, 2026 to add a dedicated section governing prediction markets, imposing two restrictions. First, domestic prediction market operators must hold a CFTC Designated Contract Market (DCM) licence to run Google ads — effectively limiting paid advertising to CFTC-registered platforms such as Kalshi and Polymarket US while excluding unlicensed or offshore operators. Second, Google bars prediction market advertising targeting five states: Connecticut (added recently), Michigan and New York (July), Ohio (June), and Nevada (earlier in the year). Those five are among the most aggressive enforcers of gambling law against the platforms, so Google's advertising platform now tracks the state enforcement map.
For UK readers, this is comparable to Google applying its gambling-advertising certification regime — under which only Gambling Commission-licensed operators may advertise gambling to UK users — to a new product category, and then geo-restricting it further by region. The DCM-licence requirement favours Kalshi and Polymarket US by raising a barrier against smaller and unlicensed competitors in the paid-acquisition channel, entrenching the incumbents. The five-state block works the other way, removing a major customer-acquisition channel in precisely the states where the platforms are fighting to keep access. They may still legally operate in some of those states under the federal preemption argument, but they cannot advertise there through Google.
Google's approach reflects a wider pattern of private intermediaries building their own compliance layers around the unresolved legal status of prediction markets. Earlier in 2026, Google restricted prediction market browser extensions in Chrome. Payment processors, app stores, and banks have all had to decide how to treat the operators while the federal-versus-state question remains open. Each intermediary that imposes restrictions creates a compliance surface independent of the formal legal outcome: even if the Supreme Court rules the platforms federally authorised and state laws preempted, Google's advertising policy is a private commercial decision it can maintain regardless. The platforms face not only the binary legal question of whether they can operate, but a granular set of commercial-access decisions by the intermediaries they depend on for distribution, payments, and acquisition.
The state-specific ad blocking is the more consequential element for growth. Google is the dominant digital advertising channel, and the inability to advertise in Connecticut, Michigan, New York, Nevada, and Ohio removes paid acquisition in large-population states — including, in New York's and Michigan's cases, significant existing sports betting markets. The platforms will lean more on organic growth, partnerships, and other channels there. Google's choice to mirror the enforcement map rather than take a position on the underlying legal question is a cautious middle path: it avoids facilitating what state regulators consider illegal gambling advertising, while still serving ads in the many states where enforcement has not materialised. As more states act — Missouri's compliance deadline is October 18, and the Sixth Circuit ruling may embolden Ohio and Tennessee — Google's blocked-state list is likely to grow, making its advertising policy a rolling reflection of where the legal fight stands jurisdiction by jurisdiction.

Kalshi Partners With Signify to Police Athlete Harassment, Codifies Anti-Abuse Rule
Kalshi announced a partnership with Signify Group on October 15 to monitor social media for abuse and threats directed at athletes, coaches, and sports personnel across the NFL, NBA, MLB, NHL, and ATP Tour. Kalshi notified the CFTC of a new rule, dated October 13, codifying athlete harassment as an 'impermissible activity', with sanctions up to financial penalties and permanent account closure. The move follows a September appeal by five major leagues and their players' unions for lifetime bans on abusive bettors.
CFTC Moves to Classify Event Contracts as Swaps — Attempting to Settle the Core SCOTUS Question by Rule
The CFTC, led by Chairman Michael Selig, moved on October 9 to explicitly classify event contracts as swaps under the Commodity Exchange Act, placing prediction market contracts under federal swap regulation. The scope covers sports, political, cultural, and weather contracts, while a separate provision excludes casino-style gambling and sportsbook wagers. Selig said the aim is to remove 'any ambiguity.' The action targets the exact question dividing the federal circuits and now before the Supreme Court — whether event contracts are 'swaps.'
Seminole Tribe Sues DraftKings as 145 Tribal Governments Urge SCOTUS to Act — But Tribes Are Split
The Seminole Tribe of Florida sued DraftKings on October 8 in Broward County court, alleging DraftKings' Pick6 and sports event contracts operate as unlicensed sportsbooks that violate the Tribe's exclusive sports betting rights under its 2021 Florida gaming compact. The same week, roughly 130 federally recognised tribes and 15 tribal organisations filed a Supreme Court amicus brief urging the Court to hear the Kalshi case, citing IGRA and unauthorised gaming on Indian lands. But the tribal community is split: several California tribes and an Oklahoma tribe have instead partnered with Kalshi.
