San Jose Mayor Behind in Polls but Ahead on Prediction Markets San Jose Mayor Matt Mahan trails in traditional opinion polls but holds a stronger position in online prediction markets, where his odds of winning the California governor’s race have surpassed those of prominent Democratic candidates like Katie Porter and Tom Steyer. While recent surveys by Emerson College, UC Berkeley, and the Public Policy Institute of California have placed Mahan below 5% in favorability, betting platforms such as Kalshi and Polymarket suggest a different narrative. On March 13, 2026, Mahan’s odds on a $4 million Kalshi pool reached 13%, ranking him higher than Steyer at 10%, former Fox News host Steve Hilton at 8%, and Porter at 3%. This contrasts with Emerson College’s poll, which gave Mahan a 3.2% favorability rating, while Steyer scored 11%, Hilton 13%, and Porter 8.4%. A separate $1.5 million Polymarket pool also showed Mahan at 8% on March 13, with bettors placing him above Porter at 5% and Riverside County Sheriff Chad Bianco at 4%. However, traditional polling places the Republican candidate, who is running as a conservative, at 11% favorability, according to the same Emerson College survey. The discrepancy highlights the divergent methods used to gauge political viability. Traditional polls rely on scientific sampling, with margins of error typically around 3%, while prediction markets depend on trader behavior and financial incentives. Political sociologist Mindy Romero, founder of the Center for Inclusive Democracy at the University of Southern California, explained that prediction markets reflect traders’ beliefs about a candidate’s likelihood of winning, not necessarily their popularity. “Online betting is just another type of horse race,” she said.#kalshi #polymarket #san_jose_mayor #matt_mahan #emerson_college

Someone made $553K on a Polymarket bet on Khamenei's death An account operating under the username "Magamyman" earned over $553,000 by placing bets on the prediction market Polymarket regarding the death of Iran’s Supreme Leader, Ayatollah Ali Khamenei, shortly before an Israeli strike killed him. The trade occurred amid escalating tensions in the Middle East, following U.S. and Israeli military actions against Iran in February 2026. The strike, which targeted Iran’s leadership, prompted retaliatory attacks on Israel and U.S. bases in the Gulf. The trader’s success drew criticism from lawmakers and critics of prediction markets, who argue that such platforms enable individuals with access to classified information to profit from lethal military operations. Polymarket saw half a billion dollars in trades predicting the timing of U.S. strikes on Iran. Senator Chris Murphy (D-Conn.) condemned the practice, calling it “insane” and vowing to introduce legislation to ban similar activities. The incident highlights broader concerns about the legal and ethical implications of betting on geopolitical events. U.S. commodity trading laws prohibit wagering on death and war, as these bets could incentivize violence and instability. However, prediction markets like Polymarket and Kalshi have operated in legal gray areas, with some traders exploiting loopholes. Kalshi, another major prediction market, faced backlash after pausing trades on Khamenei’s death and refunding fees to users. The platform’s CEO, Tarek Mansour, stated that markets tied to death are not allowed, and the company designed rules to prevent profiting from such outcomes. Traders criticized the decision as unfair, arguing they had been misled by Kalshi’s prior promotion of the market. The controversy underscores growing calls for regulatory action.#ayatollah_ali_khamenei #magamyman #polymarket #chris_murphy #tarek_mansour
