Nevada regulators secure temporary injunction blocking Polymarket event contracts

DOJ and CFTC probe George Santos for Kalshi trades against his own SOTU attendance

Kalshi's decision to self-report a high-profile user's trades to the DOJ and CFTC sets a precedent that regulated prediction markets will flag and refer suspicious congressional activity rather than risk platform liability. Any resulting enforcement action would become the first federal insider-trading case built around event contracts tied to a lawmaker's own conduct, shaping how platforms monitor politically connected traders.

Draft defense bill would bar US troops from prediction market bets

The NDAA vehicle gives the provision a near-certain floor vote, unlike standalone prediction-market legislation that typically dies in committee. Any ban that passes would immediately remove a measurable share of event-contract volume from platforms like Kalshi and Polymarket, neither of which currently geofence military bases separately from state-level restrictions.

Galaxy Digital opens OTC prediction market derivatives desk for institutional investors

Any hedge fund already clearing through Galaxy Digital can now access prediction-market exposure as a standard OTC derivative without new counterparty agreements. The bespoke structure and larger ticket sizes separate Galaxy's offering from retail platforms, giving it a direct institutional channel distinct from its existing Kalshi prime brokerage.

Becomes fourth institutional market-maker or prime-broker desk to enter prediction markets after Wintermute, FalconX for Polymarket, and Galaxy's own Kalshi unit, cementing crypto-native infrastructure firms as the dominant institutional on-ramp for event-contract exposure.

FalconX's participation as the executing broker gives Polymarket a pipeline to institutional flow that bypasses its public order books entirely. Any rival prediction market without a similar broker integration loses the race for hedge fund and prop shop volume on non-political contracts before the category scales.

Polymarket is the third major platform this week to announce institutional-grade infrastructure upgrades after Wintermute began cross-venue market making yesterday and Galaxy Digital opened its OTC desk with a $10 million Kalshi trade, cementing institutional access as the sector's central competitive front.
