No major candidates have formally announced presidential campaigns for 2028 as of early October 2026, with the field remaining in an exploratory phase ahead of the November midterms. Potential contenders including Vice President JD Vance, former Vice President Kamala Harris, California Governor Gavin Newsom, Representative Alexandria Ocasio-Cortez, and Senator Ted Cruz are engaging in positioning through polling leads, public statements, and early travel, though several figures such as Marco Rubio and Josh Hawley have recently ruled themselves out. Analysts expect a wave of declarations after the midterms through early 2027, influenced by factors like term limits, party dynamics, and primary calendar positioning. Traders assessing announcement timing before 2027 focus on these post-election catalysts and individual statements signaling intent.
