Kalshi celebrated a significant milestone by announcing a $1 billion funding round, raising the company’s valuation to around $22 billion, amid a week characterized by legal and public turmoil.
The crisis began this week with a Nevada judge issuing a temporary restraining order that could force Kalshi to halt its operations in the state, while Arizona filed criminal charges against the company for allegedly operating illegal betting activities. Kalshi dismissed these accusations as baseless, stating that disclosures were made to defend itself.
Additionally, a separate issue has emerged involving Polymarket, where an Israeli journalist reported receiving a barrage of threats from traders upset with the impact of his report on their bets. Polymarket has not responded to requests for comment.
These developments coincide with Polymarket’s growing presence in the sports world through a deal with Major League Baseball, while U.S. lawmakers propose legislation to ban certain types of prediction markets, including those linked to government actions, terrorism, wars, assassinations, or any events that an individual could influence the outcome of.
Senator Chris Murphy, one of the industry's most vocal critics and co-sponsor of the bill, described prediction markets as a "fraudulent and dangerous product" and a new source of corruption that muddles the mind. In contrast, Kalshi spokesperson Elizabeth Diana stated that the company prohibits insider trading and markets directly linked to death and war, working with regulators to ensure market safety in the U.S.
Current law grants the Commodity Futures Trading Commission (CFTC) the authority to prohibit offerings related to assassination, war, and terrorism, among other topics considered against public interest. Some market providers shy away from these categories, but confusion over the limits of these lines has led to complex scenarios, such as when some traders assumed a market predicting the fate of Iran's supreme leader could trigger a payout if he "left office" due to his death.
Meanwhile, while Polymarket operates largely outside the U.S. and offers various war markets, federal legislation is not expected to impact all of its offerings. The platform currently lists a market on whether Israeli Prime Minister Benjamin Netanyahu will be "out" by specific dates, with significant bets placed on this possibility. The market may resolve in favor of the bettors if a public figure dies, echoing a previous instance concerning Khamenei’s assassination.
Part of lawmakers' concern relates to what they perceive as signs of insider trading; the Israeli government has charged individuals with leaking classified information to citizens who placed bets on Polymarket amid the war with Iran. Senator Murphy also suspects that some trades related to the conflict might have been executed by individuals close to former President Donald Trump who may have had prior knowledge of military actions.
The Trump administration denied any involvement of its staff in insider trading, with White House spokesperson Davis Engel stating that "the only interest guiding Trump administration decisions is the interest of the American people."
As the push for federal legislation continues, state-level legal confrontations have also begun to shape the operational framework for prediction markets. Reports indicate that the Arizona Attorney General has filed criminal charges, albeit misdemeanors, which could complicate federal appeals when state criminal proceedings coincide. Legal gaming attorney Daniel Walsh described the states' trend of filing criminal charges as potentially "kryptonite" for companies like Kalshi.
Kalshi has taken preemptive legal steps, filing a motion in Ohio to prohibit the Attorney General from pursuing civil and criminal actions while it appeals a ruling that directed the company to comply with state gambling laws. Diana asserted that the charges lack basis and that the company will defend itself in court.
While official and judicial entities engage with this emerging sector, prediction platforms have maintained their ability to attract public attention; Polymarket announced the opening of a temporary bar in Washington, D.C. at the weekend to serve as a gathering spot for industry news.
