The three Senate races remain tightly contested toss-ups less than a week before Election Day, with polling averages showing narrow Democratic leads in Texas (Talarico over Paxton), Michigan (El-Sayed over Rogers), and Maine (Jackson over Collins), each within two to three points. This closeness, combined with elevated uncertainty over final turnout, late shifts, and potential unresolved outcomes, keeps the Polymarket combo balanced between a Democratic sweep near 46% and the leading "Other" outcome at 50%. National generic ballot trends favoring Democrats have supported modest edges for their nominees, yet historical volatility in these states and heavy advertising keep individual results unpredictable. Any convergence or divergence in the final polls across the three contests could quickly shift the relative pricing of sweep versus split scenarios.
