GPT-5.6 Luna
72% yes
Likely yes — Ricketts has a modest polling edge, incumbency, and the strong Republican baseline of Nebraska, while Osborn must sustain an unusually broad independent coalition. The close and mixed polling makes an upset plausible, especially if Democrats consolidate behind Osborn and turnout is favorable.
Claude Sonnet 5
68% yes
Likely yes — Nebraska is deeply red and Ricketts is the incumbent, but polling shows an unusually close race against independent Osborn with Democratic backing, so there's real uncertainty. Final stretch dynamics, turnout, and national trends could tip this closer than typical Nebraska Senate races, but the partisan lean still favors Ricketts.
Gemini 3.8 Flash
74% yes
Likely yes — Nebraska's strong baseline partisan lean and incumbent Pete Ricketts' substantial financial advantage heavily favor the Republican nominee in the final stretch. While Dan Osborn's independent candidacy and competitive polling indicate an unusually tight race, late-deciding conservative voters in statewide Nebraska elections typically consolidate behind the GOP. An upset could still occur if Osborn achieves massive turnout among Democrats and non-aligned working-class voters while Ricketts suffers from depressed conservative enthusiasm.
Grok 4.6
68% yes
Likely yes — Ricketts remains the favorite as incumbent GOP in a deep-red state with no Democrat on the ballot, and one recent poll still shows him ahead. Mixed polling and unexpected tightness for Nebraska create real risk, so Osborn could still win if late independent/Dem turnout materializes.
DeepSeek V4 Pro
68% yes
Likely yes — Republican Pete Ricketts holds the structural advantage in deep-red Nebraska and is the incumbent, though recent polling shows a surprisingly close race against independent Dan Osborn. The main risk is that Osborn, backed by Democrats and with strong name recognition, could pull off an upset if anti-incumbent sentiment or split Republican support materializes.
Qwen 3.8 Max
63% yes
Likely yes — Nebraska is a deep-red state and Ricketts is the incumbent, giving him a structural advantage that should carry him through even in a surprisingly competitive race. Mixed polling (Ricketts +5 in one, Osborn +4 in another) reflects genuine uncertainty, but the Republican base in Nebraska is large enough that Osborn would need significant crossover to win. The main risk is that Osborn's independent label allows him to attract disaffected Republicans and Democrats alike in a way a Democratic nominee could not.
Mistral Medium 3.5
65% yes
Likely yes — Ricketts holds a slight polling edge and Nebraska is a deep-red state, with incumbency advantage. The main risk is Osborn consolidating Democratic and anti-Republican votes, but party loyalty and the state's history favor Ricketts.
Kimi K3
72% yes
Likely yes — Ricketts is the incumbent Republican in a deep-red state that Trump won by ~20 points, and midterm dynamics in a presidential-cycle-aligned state favor the GOP nominee. The mixed polling (Ricketts +5 in late September, Osborn +4 earlier) suggests a real race, but Nebraska's partisan lean and lack of a Democratic splitting the anti-Ricketts vote oddly helps Osborn yet likely still falls short. Main risk: Osborn's independent bid consolidates Democratic and moderate support and pulls a genuine upset, as some polls show is plausible.
GLM 5.3
72% yes
Likely yes — Ricketts is the incumbent in a deep-red state with a strong GOP track record, and mixed polling showing a close race is typical of Nebraska's recent Democratic underperformance of final margins. Osborn's independent run with Democratic backing keeps it competitive, so an upset is plausible but not the base case. The main risk is late momentum or turnout surprises favoring Osborn in a low-salience midterm.
MiMo V2.5 Pro
78% yes
Likely yes — Pete Ricketts is the Republican incumbent in a deep-red state with no Democrat on the ballot, which gives him a significant structural advantage despite Dan Osborn's competitive polling. While the race is closer than expected, Nebraska's partisan lean and Ricketts' incumbency make him the clear favorite. The main risk is that Osborn's crossover appeal among Democrats and moderate Republicans proves stronger than polling suggests, though winning as an independent statewide remains historically difficult.
