Novig sues Wisconsin AG in its fifth state legal action over sports prediction contracts. The prediction market, which recently announced a partnership with the New York Mets, has now filed suits against regulators in five states since early August as it tests whether its sports contracts fall under existing gambling laws.

Lummis’s co-sponsorship signals the bill is being positioned partly within a broader digital payments reform narrative. cryptobriefing
