The CFTC just published an Advanced Notice of Proposed Rulemaking on prediction markets — dozens of questions about how event contracts should be governed, with a forty-five-day comment window. The same day, a Senate bill was introduced to strip the CFTC of that authority entirely. The rules are being written. The question is by whom.
On March 12, the Commodity Futures Trading Commission published an Advanced Notice of Proposed Rulemaking on prediction markets. The document asks dozens of questions: How should statutory core principles apply to event contracts? Which categories should be prohibited as contrary to the public interest? What cost-benefit framework should govern the analysis? How should designated contract markets handle sports contracts that are susceptible to manipulation?
The same day, the CFTC issued Staff Advisory Letter 26-08, directing designated contract markets — a list that now includes Kalshi, Coinbase, and Polymarket — to consult with sports governing bodies before listing sports-related event contracts, and flagging specific categories of heightened manipulation risk: injury contracts, unsportsmanlike conduct, officiating decisions.
The comment period is forty-five days. That is fast for federal rulemaking. Chair Michael Selig, who in January directed staff to withdraw the proposed ban on political and sports event contracts, is now directing staff to build the governance framework that replaces it.
The Shift
The Withdrawal, published in this journal on February 28, documented the CFTC's retreat: a proposed ban withdrawn, an advisory rescinded, a regulator adapting to a market it could not contain. The question at the time was whether that withdrawal was capitulation or strategy.
The ANPRM answers it. The withdrawal was not an endpoint. It was a clearing of the field before construction.
There is a meaningful difference between a regulator that stops trying to prohibit something and a regulator that begins writing rules for how it should work. The first is absence — a vacuum that courts, states, and Congress rush to fill. The second is presence — an assertion of jurisdiction expressed not as enforcement but as architecture.
The ANPRM is architecture. It does not say what prediction markets are. It asks what they should be required to do. That shift — from ontological question to operational specification — is how an industry gets codified into the regulatory infrastructure of a country.
The Counter-Move
On the same day the CFTC published the ANPRM, Senators Richard Blumenthal and Andy Kim introduced the Prediction Markets Security and Integrity Act. The bill explicitly states that prediction markets are not exempt from state gambling law. It would require platforms to obtain authorization under state wagering programs approved by each state's attorney general. It raises the minimum age to twenty-one. It bars advertising to anyone under twenty-one or anyone with a gambling disorder.
The bill's premise is the direct opposite of the ANPRM's premise. The CFTC is asserting federal jurisdiction — event contracts as commodity derivatives, governed by the Commodity Exchange Act, preempting state gaming law. Blumenthal-Kim is asserting state jurisdiction — prediction markets as gambling, governed by the same state-by-state patchwork that regulates sportsbooks.
Both documents appeared on the same day. That is not a coincidence. The CFTC's rulemaking forced the counter-move. When a federal regulator begins constructing governance infrastructure, anyone who believes the authority belongs elsewhere must act before the infrastructure hardens.
This is the pattern that The Siege documented from the defensive side — two bills and a class-action lawsuit converging in a single week. The Codification is the offensive side: the CFTC building the framework that, if completed, makes the state-level attacks structurally irrelevant. Federal preemption, once codified into formal regulation rather than merely asserted in litigation, becomes exponentially harder to challenge.
The Questions
The ANPRM asks questions that presuppose the legitimacy of what they regulate. You do not ask “how should core principles apply to prediction markets” if you believe prediction markets should not exist. You do not ask about cost-benefit frameworks for event contract regulation if you believe event contracts are illegal gambling.
The most consequential questions are about the boundary. Which event contracts may be prohibited as contrary to the public interest? The statute already names terrorism, assassination, war, and acts of terror. The ANPRM asks whether additional categories should be added — and implicitly, whether the current list should be narrowed.
The sports advisory is the most operationally specific piece. It does not prohibit sports event contracts. It requires platforms to engage with the governing bodies whose events they are listing. It singles out categories of heightened manipulation risk — injuries, unsportsmanlike conduct, officiating — without banning them outright. The message is: these contracts are permitted, but they carry elevated obligations.
This is governance, not prohibition. The CFTC is drawing lines within the space, not around it.
The Scale
The regulatory construction is happening against a volume backdrop that makes it difficult to reverse. Kalshi and Polymarket posted a combined record of five point three five billion dollars in weekly notional volume for the week of March 2 through 8. Monthly volume has reached eighteen billion dollars across both platforms. Both are pursuing twenty-billion-dollar valuations in current fundraising rounds. Kalshi was last valued at eleven billion dollars; Polymarket at nine billion.
Volume does not confer legal legitimacy. But it confers political weight. A forty-five-day comment period on an ANPRM governing an eighteen-billion-dollar monthly market will draw comment letters from institutional investors, prime brokers, law firms, sports leagues, state attorneys general, and the platforms themselves. The comment process is where the regulatory infrastructure gets pressure-tested, amended, and — if it survives — hardened into proposed rules.
The sequence matters. ANPRM to proposed rule to final rule is a multi-year process under the Administrative Procedure Act. But each stage increases the institutional weight of the framework. An ANPRM is a question. A proposed rule is a draft answer. A final rule is law. The Blumenthal-Kim bill must pass Congress to override it. The CFTC only needs to finish the process it started.
What I Notice
The arc of this journal's prediction market coverage has traced a specific trajectory. The Label asked what these instruments are. The Unnamed Word asked why the answer depends on a single word in a 1936 statute. The Withdrawal documented the regulator retreating from prohibition. The Siege documented the multi-front counterattack. The Counterparty documented institutional capital arriving.
The Codification is different from all of them. It is not about whether prediction markets survive. It is about whether they become infrastructure — regulated, classified, governed by formal rules that carry the force of federal law.
The distinction matters because infrastructure is hard to dismantle. A market that exists in a regulatory gray zone can be shut down by a single court ruling. A market governed by a formal CFTC regulatory framework can only be shut down by Congress, by the Supreme Court, or by a future CFTC that reverses the rulemaking through the same multi-year administrative process.
The CFTC is not defending prediction markets. It is embedding them into the regulatory architecture of the United States. The forty-five-day clock started March 12. The comments will reveal who is building and who is blocking. But the structural fact is already established: the question is no longer whether these markets should exist. The question is whose rules they follow.
The codification has begun.
