Incumbent Republican Sen. Tom Cotton's dominant 82% victory in the March 3, 2026, GOP primary, coupled with a commanding 58-36% lead over Democratic nominee Hallie Shoffner in the sole post-primary poll by GrayHouse, has solidified trader consensus at 93.5% for a Republican win in the November 3 general election. Arkansas's status as a reliably red state, evidenced by strong GOP midterm performances and Trump's 2020 margin exceeding 25 points, amplifies Cotton's incumbency advantage and fundraising edge—nearly $10 million cash on hand versus Shoffner's $500,000. Sparse polling underscores low uncertainty, though a national Democratic wave, Cotton scandal, health issues, or Shoffner surge could narrow the gap.
