Traders assign a 95% probability to "Nobody" because John Cornyn has issued no endorsement in the Texas Senate race and has given no public indication of plans to do so. This stance aligns with his position as a senior senator balancing Senate leadership duties, primary dynamics, and party coalition pressures without committing support. Low odds for other listed candidates reflect the absence of recent statements, events, or procedural moves signaling alignment. Late developments that could still shift the market include an official announcement, response to primary results, or pressure from national Republican leaders ahead of the November election.
