A US federal judge has granted Robinhood’s request to reopen its legal challenge against the Commonwealth of Massachusetts, marking a significant procedural development in the dispute over prediction markets and sports-related event contracts.
According to an electronic order entered on January 8, Judge Richard G Stearns approved Robinhood Derivatives’ motion for reconsideration, reversing a prior dismissal that had rejected the company’s request for a preliminary injunction.
The court has now allowed Robinhood 21 days to file an amended complaint, after which Massachusetts will have 14 days to respond
The original dismissal was based on the court’s assessment that Robinhood’s sports-related event contracts were offered solely through Kalshi, which remains the subject of a separate enforcement action by Massachusetts authorities.
In its reconsideration filing, Robinhood argued that this premise was no longer accurate, as it has since contracted with ForecastEx, a second federally regulated designated contract market.
Judge Stearns agreed that the change warranted reconsideration, writing that the court’s earlier order had been “premised on Robinhood offering sports wagering only through the Kalshi DCM” and that the addition of ForecastEx constituted a material change in circumstances
The case centers on whether Massachusetts can apply its sports wagering laws to event-based derivatives traded on federally regulated exchanges.
Robinhood has argued that state enforcement efforts are pre-empted by federal commodities law, while Massachusetts regulators maintain that sports-related event contracts fall within the scope of state gambling restrictions.
The reconsideration motion also pointed to a November 13 letter sent by Massachusetts authorities to licensed operators, warning against offering sports-related event contracts.
Robinhood argued that the letter, combined with enforcement action against Kalshi, created a credible and imminent threat to its own operations, chilling commercial partnerships and justifying judicial review.
The decision to reopen the case comes amid broader regulatory scrutiny of prediction markets and adjacent products. Robinhood has continued to expand its event-based offerings, including the recent launch of NFL-related combinations that mirror traditional parlays in structure, while emphasizing that its products operate within a derivatives framework rather than under sportsbook licensing.
The Massachusetts proceedings will now resume, with the amended complaint expected to reflect Robinhood’s expanded exchange relationships and the evolving enforcement landscape.
Robinhood agreed in November to acquire a 90% stake in MIAX Derivatives Exchange as part of a wider push into regulated futures and event-based markets, strengthening its position within US commodities infrastructure
