CFTC Moves to Classify Event Contracts as Swaps

The U.S. Commodity Futures Trading Commission has taken two concrete regulatory steps to cement its claim that prediction market contracts are swaps under federal law, a classification that, if it holds, would reshape how accounting firms and CFOs must recognise, measure, and disclose client exposure on platforms such as Kalshi and Polymarket. The agency issued an interim final rule and separately proposed a broader regulatory amendment, both aimed at drawing a clear line between casino-style gambling (outside CFTC reach) and event contracts (inside it).

What the CFTC Has Actually Done

The agency acted on two parallel tracks at the same time, which is worth unpacking carefully because each track carries different legal weight and a different timeline.

The interim final rule

An interim final rule takes effect immediately as agency policy. It does not wait for a standard notice-and-comment cycle to close. The CFTC used this mechanism to define what is not a swap: casino-style wagering. By carving gambling out of the swap definition first, the agency strengthens the logical inverse, that event contracts on regulated prediction market platforms remain inside the swap definition and therefore inside CFTC jurisdiction. Public comments are still accepted during implementation, but the rule is live.

The proposed rule

The companion proposal goes further. It would explicitly bring "event contracts, including those based on sports, politics, cultural, and weather-related events" that are routinely traded on prediction market platforms into the existing federal swaps regulatory framework. A 30-day comment window applies, which is notably short by regulatory standards, suggesting the agency wants to move quickly. Both actions follow an announcement made less than two weeks before they were published, underscoring the pace at which Chairman Mike Selig, currently the sole sitting commissioner on a body designed to have five members, is pushing this agenda.

Why the CFTC Is Moving Now

The timing is not arbitrary. Several states have filed lawsuits against the CFTC arguing that sports betting activity on prediction market platforms falls under state gambling law, not federal derivatives law. The litigation has produced mixed results at the appellate level: one federal appellate decision sided with the CFTC, while two others supported the states. The dispute has now reached the U.S. Supreme Court, which has been asked to resolve the jurisdictional question definitively.

The legal strategy behind the rulemaking

By codifying its interpretation in binding agency rules before the Supreme Court takes up the case, the CFTC gives itself a stronger administrative record to defend. Courts traditionally give some deference to an agency's reasonable interpretation of the statutes it administers, though the extent of that deference has narrowed in recent years. TD Cowen policy analyst Jaret Seiberg noted in a client note that the interim final rule appears designed to improve the agency's litigation posture, while cautioning that whether it actually achieves that goal remains an open question. The core concern raised by state opponents is that a broad swap definition could inadvertently make any wager placed at a state or tribal casino or sportsbook federally illegal, a reading the CFTC is now expressly trying to foreclose by carving out casino gambling.

A commission operating with one member

It is unusual for a multi-member independent agency to move this fast on contested policy. The reason here is structural: the CFTC is supposed to operate with five commissioners but currently has only one, Chairman Selig. That means Selig can set policy without internal dissent or the need to build a majority. President Trump has not yet named additional commissioners. A parallel vacancy situation exists at the Securities and Exchange Commission, which has two members instead of its statutory five. The administration has made a deliberate effort to reduce Democratic representation at financial regulatory agencies, and the thinly staffed commissions are a visible result.

Accounting and Reporting Implications for Firms

The CFTC's rulemaking may feel like a jurisdictional dispute between regulators and states, but its downstream accounting consequences are real and immediate for any firm or client with prediction market exposure. Robust crypto compliance reporting processes will be essential as this framework takes shape.

Swap classification triggers derivative accounting

If event contracts are legally swaps, they are derivatives under both US GAAP (ASC 815) and IFRS 9. That means the following obligations come into play for any entity holding open positions:

• Positions must be recognised on the balance sheet at fair value, not at cost or notional value.
• Changes in fair value flow through the income statement each reporting period unless hedge accounting criteria are met and documented.
• Hedge accounting for event contracts is likely difficult to qualify for in practice, given the speculative nature of most prediction market positions.
• Counterparty credit risk disclosure requirements under ASC 820 or IFRS 13 apply to fair value measurement.

For clients who have been treating prediction market positions as simple wagers or miscellaneous investments, a formal swap designation would require a reclassification and potentially a restatement of prior period financials if positions were material.

Swap data reporting obligations

Swaps under CFTC jurisdiction are subject to swap data repository reporting requirements. If the proposed rule is finalised, platform operators would bear primary reporting duties, but institutional participants may face their own reporting obligations depending on their counterparty status. Accounting teams maintaining CFTC's broader crypto regulatory framework watch lists should add event contract classification to their monitoring lists now, ahead of any final rule.

Tax treatment remains a separate question

Regulatory classification as a swap does not automatically resolve federal income tax treatment. Section 1256 contracts receive mark-to-market tax treatment with a 60/40 long-term/short-term capital gain split, but not all swaps qualify as Section 1256 contracts. If event contracts are treated as notional principal contracts or as ordinary swaps outside Section 1256, the tax accounting approach differs materially. Tax advisers should not assume that the CFTC's regulatory label maps directly onto the Internal Revenue Code's categorisation. The IRS has not issued guidance specifically addressing prediction market contracts, so a facts-and-circumstances analysis will be required for each client situation until it does.

What Accounting Firms Should Do Right Now

The interim final rule is already in effect. The proposed rule has a 30-day comment window. That compresses the timeline for firms to form a view and advise clients.

Immediate client screening

Identify any client that holds open positions or has traded on prediction market platforms in the current or prior financial year. Materiality thresholds matter: a single large position could require balance sheet reclassification even if overall crypto exposure is minor. Digital asset accounting software that tracks positions across multiple platform types will need configuration updates to flag event contract activity separately from spot crypto or conventional derivatives.

Engage on the comment period

A 30-day comment period is short, but it is real. Accounting firms and trade associations representing CFOs have standing to submit comments on how the proposed rule's scope and definitions interact with financial reporting standards. The CFTC's proposed text on what qualifies as an event contract will determine audit scope. Vague boundaries create auditor uncertainty about which client activities require derivative disclosures, and comment letters can push for clearer definitional lines.

Watch the Supreme Court docket

The Supreme Court's eventual decision will be the definitive word on whether the CFTC's jurisdictional claim survives. If the Court rules against the CFTC, the interim final rule and any finalised proposed rule could be vacated, requiring firms to unwind any accounting changes made in reliance on the swap classification. Building scenario-based accounting memos now, one for a CFTC win and one for a CFTC loss, will save time when a decision arrives. The US crypto market structure rules and political durability analysis published earlier this year is useful background on how regulatory reversals affect compliance planning cycles.

The Broader Market Structure Picture

This rulemaking sits within a larger effort by the CFTC under Selig to expand the agency's footprint across digital and non-traditional financial products. Prediction markets are one front; leveraged retail crypto trading rules are another. The common thread is a CFTC that is asserting broad jurisdiction over financial contracts that have historically existed in regulatory grey zones.

For firms advising clients in the digital asset space, the pattern matters as much as any individual rule. The direction of travel at the CFTC is toward more, not less, federal oversight of instruments that trade on outcomes rather than underlying asset prices. That trajectory has direct implications for how crypto bookkeeping software and audit workflows are configured: product taxonomies will need to accommodate a growing list of regulated contract types, not just spot assets and conventional futures.

Platforms operating in this space, Kalshi being the most prominent example named in the CFTC's own rulemaking, have consistently aligned with the CFTC's position because federal-only oversight is simpler for their business model than a patchwork of state gambling licensing requirements. If the CFTC prevails legally, those platforms will sit firmly within the federal derivatives regulatory perimeter, with all the trade reporting, record-keeping, and counterparty obligation requirements that entails.
