Chicago’s CME has abruptly replaced powerhouse law firm Jenner & Block in its lawsuit against the Commodity Futures Trading Commission, shaking up a case that could help decide who gets to offer perpetual crypto futures in the United States. The switch came after Jenner & Block moved to withdraw on Thursday, and Zuckerman Spaeder partner Aitan Goelman filed a notice of appearance for CME.
Court records show Jenner & Block filed a formal motion to withdraw and submitted a proposed order in the U.S. District Court for the District of Columbia, and a notice of appearance for Aitan D. Goelman was docketed on July 2, according to CourtListener. On the public docket, the filings appear as a motion titled “Motion to Withdraw as Attorney for Plaintiff” and a separate notice of appearance for new counsel.
In its motion, Jenner & Block said unidentified positional conflicts with other clients required the firm to exit the case, a claim reported by Reuters. The filing did not specify which clients or positions created the conflict, leaving the change to feel abrupt for market watchers and for CME’s own leadership.
CME told Reuters it was surprised that Jenner belatedly discovered the apparent conflicts and withdrew at this stage of the litigation. The CFTC has brushed off the suit as “frivolous” and accused CME of waging “lawfare” instead of competing in the market, a sign that neither side is exactly in a mood to de-escalate.
What's at stake
CME’s complaint asks the court to void the CFTC’s May 29 order approving KalshiEX’s bitcoin perpetual futures contract and a related Policy Statement on perpetual contracts, alleging the agency acted arbitrarily and capriciously under the Administrative Procedure Act, according to the complaint on the public docket at CourtListener. A ruling in CME’s favor could narrow which platforms may list perpetual-style products onshore, while a decision siding with the CFTC would solidify a regulatory path for exchanges such as Kalshi and Coinbase to offer those contracts.
Who is Aitan Goelman?
Aitan D. Goelman, a former director of enforcement at the CFTC who is now a partner at Zuckerman Spaeder, filed the notice of appearance for CME. His firm bio highlights decades of enforcement and trial work. According to Zuckerman Spaeder, Goelman leads the firm’s securities and commodities litigation practice and brings direct agency experience to CME’s legal team.
What happens next
The judge will decide whether to allow Jenner & Block’s withdrawal and will set a schedule for further briefing on the merits of CME’s challenge. Expect procedural motions and tightly focused briefs in the coming weeks as both sides position themselves ahead of more substantive arguments.
Why it matters
The case turns on whether perpetual contracts should be treated as swaps under Dodd‑Frank or as futures, a legal distinction that shapes margin rules, surveillance obligations and which trading venues may offer heavily leveraged products in the United States. Market participants are watching closely because the outcome could either help shield incumbents like CME or open the door to more onshore competition in high leverage crypto derivatives.
