    "Widespread media coverage of Democratic optimism is at odds with prediction-market pricing, which strongly favors a Republican House hold.",
    "The companion Kalshi contract (CM-EVT-T5VXKJT451) at 71% for Republicans controlling at least one chamber is a weaker read, consistent with Senate uncertainty dampening the overall-chamber probability.",
    "The Polymarket Senate control contract (CM-EVT-M9WJY06T90) at 73% for one party reveals the House-Senate spread: the House is seen as far more settled than the Senate race outcome."
