The CFTC closed its second mention-markets insider-trading case in four weeks, ordering a former White House teleprompter operator to hand over profits and pay a penalty for trading Kalshi contracts on advance knowledge of presidential speech text, a sign that surveillance and enforcement keep moving on their own track regardless of the state-preemption fight. That fight itself kept escalating in the wake of Friday's Ninth Circuit loss for Kalshi in Nevada, with the resulting circuit split now putting a Supreme Court cert petition on a real clock. Elsewhere, DraftKings shifted more parlay-style volume onto its own exchange and Polymarket rebuilt its compliance bench ahead of a fall trading season it hopes will support a valuation north of $20 billion.

CFTC settles second mention-markets insider-trading case, orders ex-White House staffer to pay $172,000
The CFTC settled charges against Gabriel Perez, a former White House teleprompter operator, over trades on Kalshi mention-market contracts tied to specific words in President Trump's prepared remarks; Perez traded roughly an hour ahead of delivery using advance access to the speech text between December 2025 and early 2026. The consent order, entered without an admission of findings, requires about $107,500 in disgorgement plus a $65,000 civil penalty (discounted for cooperation) and a three-year trading ban. It is the CFTC's second settlement in four weeks over event-contract insider trading by someone with privileged advance access to the underlying event, following the July 31 Santos case, and keeps compliance pressure on any operator still offering mention-style contracts.

Ninth Circuit's Nevada loss sharpens circuit split, puts a Supreme Court cert petition on a fast clock
Commentary following Friday's Ninth Circuit ruling against Kalshi in the Nevada case converged on the same point: the decision squarely conflicts with the Third Circuit's pro-Kalshi Flaherty ruling, and a circuit split is the classic trigger for Supreme Court review. New Jersey's deadline to file a cert petition in Flaherty v. Kalshi, already pushed back repeatedly, falls September 3, just days after the Ninth Circuit ruling landed, and legal commentators expect the fresh split to strengthen the case for the Court to take it up. Compliance and legal teams should treat a Supreme Court grant as increasingly likely rather than speculative, and plan for continued state-by-state enforcement uncertainty until any such ruling arrives.

Defense in CFTC's Polymarket insider-trading case fights agency's bid to weigh in on swap definition
In CFTC v. Van Dyke, the soldier accused of trading more than 436,000 Polymarket "Yes" shares on nonpublic intelligence about a Venezuela operation, defense counsel filed on August 24 opposing a CFTC request to submit an amicus brief on whether Polymarket's event contracts are swaps under the Commodity Exchange Act, calling the agency a "regulatory wolf." The stayed civil case (paused pending the criminal trial, expected no earlier than late 2026) makes the amicus fight a proxy battle over the same swap-classification question now dividing the circuit courts. Platforms should note that even paused enforcement matters remain a live vehicle for the CFTC to press its jurisdictional theory.

DraftKings shifts more parlay volume in-house as DKeX self-certifies nine football contracts
Railbird Exchange, doing business as DKeX and owned by DraftKings, self-certified nine football event contracts with the CFTC ahead of the NFL season, covering game-side and totals equivalents, player-proposition markets, and season-award contracts such as MVP, settled on official confirmation by the awarding body. DKeX also self-certified "combos," its parlay-equivalent multi-leg product, previously routed through exchange partner Crypto.com, allowing DraftKings to capture that volume and the associated economics in-house. Since self-certification requires no CFTC review or approval, competitors should expect similar vertical-integration filings across the sector as operators race to own more of the parlay-style trading stack before kickoff.

Polymarket rebuilds compliance bench with hires from Robinhood, Coinbase, Nasdaq, and the FBI
Polymarket named five senior executives ahead of the NFL season and November midterms: Megan McGrath (ex-Robinhood) as chief compliance officer of its U.S. exchange, Natalie Oblazny (ex-Coinbase) as head of regulatory affairs, Shana Bautista (ex-FBI, ex-Coinbase) as global head of investigations and intelligence, Paul Jordan (ex-Nasdaq) as chief risk officer, and Travis VanderZanden as chief growth officer. The buildout follows a CFTC investigation triggered by fabricated promotional content targeting U.S. users and lands as Polymarket pursues a roughly $1 billion raise at a valuation above $20 billion, making institutional-grade compliance credibility a precondition for that round rather than a nice-to-have. Operators still running lean compliance teams should read the hiring list as a rough benchmark of what regulators and investors now expect.
