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 prediction market operators to hold a CFTC Designated Contract Market license to run ads — a requirement that favors Kalshi and Polymarket US over unlicensed rivals. Google also bars prediction market ads targeting five states where enforcement is most active: Connecticut (added recently), Michigan and New York (July), Ohio (June), and Nevada (earlier in the year). The policy makes Google's advertising platform mirror the state-by-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. The new policy imposes two distinct restrictions. First, domestic prediction market operators must hold a Commodity Futures Trading Commission Designated Contract Market (DCM) license to run ads on Google — a requirement that effectively limits 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 users in five states: Connecticut, which was added recently, joining Michigan and New York (added in July), Ohio (June), and Nevada (added earlier in the year). The five states are among the most aggressive in enforcing gambling laws against prediction market platforms, and Google's decision to block ads in exactly those jurisdictions makes its advertising platform track the state enforcement map.
The license requirement and the state blocks work in opposite directions for the major platforms. The DCM-license requirement is favorable to Kalshi and Polymarket US: by restricting paid advertising to CFTC-registered operators, Google raises a barrier against smaller or unlicensed competitors and reinforces the two leaders' dominant position in the paid-acquisition channel. A new entrant without a DCM license cannot buy Google ads to compete for users, which entrenches the incumbents. The five-state ad block, by contrast, is unfavorable: it removes a major customer-acquisition channel in precisely the states where the platforms are fighting to maintain access. The platforms can still legally operate in some of these states under the federal preemption argument while the litigation proceeds, but they cannot advertise there through Google, which constrains their ability to grow the user base in contested markets.
Google's approach reflects a broader pattern of private platforms and 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 prediction market operators while the federal-versus-state jurisdiction question remains unsettled. Each intermediary that imposes its own restrictions creates a compliance surface independent of the formal legal outcome: even if the Supreme Court ultimately rules that the platforms are federally authorized and state gambling laws are preempted, Google's advertising policy is a private commercial decision that Google can maintain regardless of the legal ruling. The platforms face not only the binary legal question of whether they can operate, but a more granular set of commercial-access decisions by the intermediaries they depend on for distribution, payments, and customer acquisition.
The state-specific ad blocking is the more consequential element for the platforms' growth. Google is the dominant digital advertising channel, and the inability to run ads in Connecticut, Michigan, New York, Nevada, and Ohio removes paid acquisition in states with large populations and, in New York's and Michigan's cases, significant existing sports betting markets. The platforms will rely more heavily on organic growth, partnerships, and other channels in those states. 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 the risk of facilitating what state regulators consider illegal gambling advertising, while continuing to serve ads in the many states where enforcement has not materialized. As more states act — Missouri's compliance deadline is October 18, and the Sixth Circuit ruling may embolden Ohio and Tennessee further — 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, that codifies athlete harassment as an 'impermissible activity' on its platform, 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, and positions Kalshi ahead of the integrity concerns that sports leagues and regulators have raised about prediction market sports contracts.
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, which would place prediction market contracts squarely 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' about these contracts. The action targets the exact question dividing the federal circuits and now before the Supreme Court — whether event contracts are 'swaps' — and represents an attempt by the federal regulator to settle that question by rule while the courts remain split.
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 that 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, a coalition of roughly 130 federally recognized tribes and 15 tribal organizations filed a Supreme Court amicus brief urging the Court to hear the Kalshi case, arguing the contracts are sports bets and that platforms have operated on Indian lands without tribal authorization under IGRA. But the tribal community is split: several California tribes and an Oklahoma tribe have instead partnered with Kalshi to build apps and online casinos on its platform.
