CFTC Proposes a First Rule for Banning Prediction-Market Contracts

The Commodity Futures Trading Commission proposed on Wednesday the first federal rule setting out when a prediction-market contract can be prohibited. Under the draft, a contract can be banned only if it passes a three-part test: it is based on a specified event, it falls into a prohibited category such as war, terrorism, assassination, illegal activity or gaming, and the commission makes a formal public-interest determination against it. Until now there was no such test. The agency handled these questions case by case. The proposal names Kalshi, Polymarket and Crypto.com as the platforms it has in view.

How the review would work

A contract flagged for review would get a 90-day window, during which the commission would weigh it against the test. Sports contracts, the draft says, would generally be treated as in the public interest, which removes the single largest category of event contracts from the risk of a ban. Any final rule would take effect 60 days after the process completes. CoinDesk, which reported the proposal on Wednesday, noted that the commission was operating with a single seated member, Chairman Mike Selig. A rule of this weight is usually the product of a full commission. This one is not, and the draft does not say whether a fuller commission would revisit it.

Why the test matters more than the list

What the draft changes is the burden. A contract would be presumed permissible unless the commission can show it meets all three prongs, and the third prong requires a formal finding on the record. For platforms that have spent the past year arguing market by market, a presumption in their favour is the substantive shift. The definitions of "gaming" and "illegal activity" are where the arguments will concentrate, because they are the categories broad enough to reach contracts the platforms already list.

Three prongs, three different jobs

Each part of the test does something distinct. The first, that a contract be based on a specified event, is a threshold that almost every listed market clears; it exists to keep the rule from reaching ordinary futures. The second, membership of a prohibited category, is the list itself, and the list is the only part of the draft that names conduct. The third, a formal public-interest determination, is procedural: it forces the commission to write down its reasoning and vote on it, which means a ban can be challenged on the record. Together they replace discretion with procedure. A platform that loses under this test will at least know why.

The proposal landed on a day when May inflation data left bitcoin flat near $61,000 and spot ETFs were still in a run of outflows that had reached $4.37 billion over thirteen sessions as of last week. Prediction markets sit outside that flow entirely. Their exposure is regulatory, and this is the first time the regulator has written its rules down.

Two things the reporting did not say

The coverage available on Wednesday did not give the length of the comment period, nor whether the 90-day review clock would start from a platform's listing or from the commission's own notice. That second detail decides how much a platform can list before anyone can object. We could not establish it from the material published so far. It is the first question the platforms will ask.
