How Event Contracts Get Listed
Most people assume a new prediction market needs approval before trading. That’s not how it works in the US. A designated contract market can file a self-certification with the Commodity Futures Trading Commission stating the product complies with the law. Then trading can start almost immediately. No approval required. That single procedural fact explains why markets on a court ruling, a data release, or a tournament appear within days. It also explains the industry’s central legal vulnerability.
The Trapdoor in Dodd-Frank
Congress paired that speed with a trapdoor in 2010 through the Dodd-Frank Act. The Special Rule allows the CFTC to prohibit an event contract even after listing if it involves one of five enumerated activities: unlawful activity, terrorism, assassination, war, and gaming. Plus any similar activity the Commission designates. The catch: three key words in the statute were never defined: “involve,” “gaming,” and “public interest.” That ambiguity has caused fifteen years of unpredictable outcomes.
The Review Process
Rule 40.11 sets the procedure. If a submission may involve an enumerated activity, the CFTC can start a 90-day review. It must ask the exchange to suspend trading during that time. It can solicit public comment. By day 90, it must issue an order approving or disapproving. If no order comes, the contract keeps trading. The clock runs against the regulator. That’s unusual in finance and gives exchanges a structural advantage.
Case History Shaped Practice
Four episodes shaped current practice. In 2012, an exchange withdrew its certification under pressure before a final order. PredictIt operated under a no-action letter, later leading to litigation. In 2023, the CFTC barred Kalshi from listing congressional control contracts. Kalshi challenged it, and the litigation ultimately cleared the way for regulated election markets. Then in 2024, a broader proposal was abandoned. The pattern: unresolved definitions resolved through withdrawal, litigation, or abandonment.
The 2026 Rulemaking
This June, the CFTC proposed new rules. They offer a settlement-based test for when a contract “involves” an activity. They define “gaming.” They lay out public-interest factors in a structured three-step inquiry. And they formalize procedures with written statements and exchange responses. Self-certification remains intact. The CFTC seems to want speed preserved but discretion disciplined. The comment process is now underway with exchanges, state regulators, and consumer advocates all filing competing arguments.
What It Means in Practice
For participants, three things matter. New markets appear fast but can vanish if the CFTC opens a review. The exchange is the first line of judgment, and quality varies. The biggest legal questions—sports, political contracts, anything near gambling—get resolved through this obscure procedural regulation. Anyone following the sector’s legal trajectory is following Part 40. The mechanism that makes American prediction markets fast is the same that makes them revocable. Hold both facts in mind when participating.
