Incumbent Republican Pete Ricketts holds a clear edge in the November 2026 Nebraska Senate race as he seeks a full term after winning his 2024 special election and the May Republican primary with over 80 percent of the vote. Independent Dan Osborn, backed by state Democrats after their nominee withdrew, presents the main challenge in a contest rated lean or likely Republican by forecasters. Recent polling averages show a tight race, with Ricketts at roughly 46-48 percent and Osborn near 44-47 percent, narrower than expected in the heavily Republican state. Ricketts has highlighted his legislative record and experience while criticizing Osborn, and a recent Trump rally boosted the incumbent. Traders assign the independent outcome substantial probability due to Osborn’s fundraising, union background, and polling momentum, while the negligible Democratic share reflects the party’s decision to clear the field.
