Alexi Giannoulias holds the leading position in the 2027 Chicago mayoral race due to his substantial fundraising advantage, name recognition as Illinois Secretary of State, and endorsements from trade unions and business interests. Recent campaign finance reports show him with roughly $19 million on hand, far outpacing incumbent Brandon Johnson’s approximately $379,000 and other declared candidates. Giannoulias formally entered the contest in August, emphasizing public safety measures such as hiring additional officers and restoring certain technology programs, alongside priorities like affordable housing and minimum wage increases. Johnson announced his reelection bid in September amid polls indicating limited voter enthusiasm for another term. A recent court ruling cleared procedural hurdles for Giannoulias and others pursuing dual candidacies ahead of petition filing deadlines in late October, with the February election approaching.
