Polymarket and Kalshi sharply raised implied odds that Homeland Security Secretary Kristi Noem will be the first Trump cabinet member to leave — jumping from about 12% on Jan. 21 to roughly 40–43% after backlash over her defense of the fatal shootings of Alex Pretti and Renée Good. Noem leads other names like AG Pam Bondi and Labor Secretary Lori Chavez-DeRemer. Bipartisan Republican criticism, including calls for her to step down from Sens. Thom Tillis and Lisa Murkowski, compounded the market move. One market now prices a 32% chance Noem is out by March 31 and a 24% chance she’s impeached by the end of 2026. Critics say her initial claims that the victims were “attacking” ICE agents were unsupported by video and eyewitness accounts; Democrats note removal wouldn’t necessarily resolve broader DHS policy issues.

Negative sentiment: prediction markets (Polymarket, Kalshi) raised implied odds from ~12% to ~40–43% that Noem will be the first cabinet member to leave after backlash, and bipartisan Republican criticism (Tillis, Murkowski) compounded the move. Low impact: the article reports political developments and prediction-market probability changes (including a 32% chance of departure by March 31 and 24% chance of impeachment by end-2026) and does not report market-moving financial asset news.
