According to Protos, Robinhood disclosed in its quarterly report filed on October 28 that it has neither collected nor paid federal excise taxes on event contracts, arguing that these contracts are not subject to the tax. The company also warned that an adverse tax ruling could have a material impact and potentially render the related business economically unviable. The report further noted that the response deadlines for Supreme Court petitions involving Robinhood, Crypto.com, and Kalshi are all set for December 7. This date marks the litigation response deadline rather than a scheduled ruling date. The underlying dispute primarily centers on state gambling regulation and the legal classification of event contracts, with the report clarifying that the Supreme Court will not directly rule on the narrow issue of federal taxes.
