2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
Based on the provided chart data, this market exhibits a stable, sideways trading pattern with very low liquidity. The price has remained within a narrow 5-point range, between a low of 5.0% and a high of 10.0%, since trading began. The market opened at 10.0% and is currently trading at 9.8%, indicating minimal net change over its history. There have been no significant price spikes or drops to analyze, and the absence of any major news or developments in the provided context aligns with this lack of volatility. The price of 10.0% appears to be an initial resistance level, while 5.0% has acted as a support floor.
The most notable characteristic of this market is its extremely low trading volume, with only 59 contracts traded in total. This low level of activity suggests a lack of broad market participation and conviction. In such a thin market, even small trades can influence the price, meaning the current price may not reflect a strong consensus. The sentiment, as reflected by the price, indicates that traders are consistently assigning a low, roughly 1-in-10 probability to this outcome. The sideways trend suggests that, among the few participants, no new information has emerged to significantly alter their initial assessment.

Market Discussion
Alexi Giannoulias is the strong favorite in this market at 56%, while current Mayor Brandon Johnson faces significant 'No' sentiment, with traders citing his low approval ratings as a key argument against his re-election. There is discussion among participants regarding the inclusion of additional candidates like Mike Quigley, who recently indicated a potential run. A notable insight is the concern raised by traders that this market might be a duplicate and potentially flawed, with advice to trade on an alternative market offering more candidates and volume.
4. What are Mayor Brandon Johnson's crime handling approval ratings?
| Crime handling approval | 33.3% [^] |
|---|---|
| Overall job approval | 26% (August 2025) [^] |
| Overall performance disapproval | 57% (Lincoln Poll) [^] |
Mayor Brandon Johnson's crime handling approval rating is notably low. Approximately one-third of Chicagoans expressed approval for his handling of crime early in his term, translating to an approval rating of about 33.3%. Conversely, roughly 2 in 3 Chicagoans disapprove of his performance in this area [^]. This figure is below the 40% threshold typically indicating high vulnerability for a public official.
Broader polls also indicate low overall job approval. Mayor Johnson's overall job approval has similarly remained low. A University of Chicago NORC survey conducted in August 2025 reported his general job approval rating at 26% [^]. Earlier polls from the Lincoln Poll indicated that 57% of Chicagoans disapproved of his overall performance [^]. These general approval figures also consistently fall below the 40% vulnerability mark.
Quarterly trend data on crime handling is not available. While these polls offer insight into public sentiment at various points, the available research does not provide a consistent series of quarterly polls specifically on his handling of crime that extends through the end of 2026. Therefore, a definitive quarterly trend or projection for this specific aspect of his performance cannot be established from the provided sources.
5. Which Moderate Challenger Shows Strongest Financial Backing for Chicago Mayor?
| Alexi Giannoulias Fundraising | Approximately $12 million [^] |
|---|---|
| Giannoulias Fundraising Position | Significant financial advantage over other potential mayoral candidates [^] |
| Mike Quigley's Candidacy | Announced intention to run for mayor in 2027 [^] |
Alexi Giannoulias holds a significant fundraising lead for the 2027 Chicago mayoral race. He has already amassed approximately $12 million, positioning him as the frontrunner among potential moderate challengers to secure significant financial backing or endorsements by Q1 2027 [^]. This substantial fundraising total indicates broad support, including from the business community, which is likely to translate into further endorsements or financial contributions from key organizations such as the Chicagoland Chamber of Commerce or the Economic Club of Chicago.
While other potential moderate challengers are attracting attention, none currently demonstrate comparable publicly disclosed financial backing specifically for the 2027 mayoral election. For example, Bill Conway previously received encouragement from business and union leaders regarding a potential 2022 mayoral run [^], and U.S. Representative Mike Quigley has officially declared his candidacy for 2027 [^]. However, neither Conway nor Quigley, nor other mentioned hopefuls, have reported fundraising totals for the upcoming election that are comparable to Giannoulias's established financial advantage [^]. This makes Giannoulias the most likely candidate to secure and disclose significant financial backing or endorsements from Chicago's key business organizations by the first quarter of 2027.
6. How Did CTU Support Mayor Johnson During 2026 Negotiations?
| CTU Leadership Aligned With Mayor | President Stacy Davis Gates [^] |
|---|---|
| Key Issue of Alignment | Opposition to CPS CEO on May Day plans [^] |
| Nature of Support | Public alignment with Mayor Johnson [^] |
CTU leadership publicly aligned with Mayor Johnson during 2026 negotiations. During the 2026 union contract negotiations, the Chicago Teachers Union (CTU) leadership, including President Stacy Davis Gates, actively supported Mayor Johnson on critical issues. A notable instance was their shared opposition to Chicago Public Schools (CPS) CEO Dr. Macquline King's plans for schools to remain open on May Day in April 2026. This collaborative stance publicly characterized Mayor Johnson's position favorably when their interests converged [^].
This alignment indicated a unified front, avoiding public criticism. The public alignment from Stacy Davis Gates and the CTU, exemplified by the May Day issue during negotiations, suggested they avoided public criticism of Mayor Johnson. Their actions instead highlighted a collaborative relationship and shared objectives. This overall characterization of support signaled a strong, unified front where their interests converged, indicating a lack of critical fracture in Mayor Johnson's core political base based on the available information [^].
7. How Do Potential Challengers Impact Mayor Johnson's Re-election Chances?
| Mayor Johnson Unfavorable Rating | 80% (February 2025) [^] |
|---|---|
| Johnson Trails Giannoulias | Double digits (hypothetical 2026 polling) [^] |
| Giannoulias Campaign Funds | $18.3 million (as of April 2026) [^] |
Mayor Brandon Johnson faces significant challenges, while Alexi Giannoulias shows strong potential. Recent polling indicates Mayor Johnson's considerable public opinion difficulties, with a Suffolk-Tribune poll revealing more Chicagoans view him unfavorably than favorably [^]. A February 2025 poll further highlighted Mayor Johnson's vulnerability, showing only 7% of voters viewed him favorably, 80% unfavorably, and his re-election support in a crowded field stood at just 8% [^]. Critically, the Suffolk-Tribune poll also indicated Johnson trails hypothetical challengers, including Illinois Secretary of State Alexi Giannoulias, by double digits [^]. Giannoulias also possesses a substantial financial advantage, holding $18.3 million in campaign funds compared to Mayor Johnson's $813,125 as of April 2026, providing him with significant resources for a potential campaign [^].
Giannoulias appears better positioned than Vallas to consolidate anti-Johnson votes. In the 2023 mayoral election, Paul Vallas initially held a lead but ultimately saw his advantage shrink to two points before losing to Brandon Johnson [^]. While Vallas performed strongly in many lakefront and North Side wards, successfully consolidating a significant portion of the anti-Johnson vote in those areas in 2023 [^], his overall campaign struggled to unite a broader coalition. As a well-known Democratic official with a strong fundraising base and hypothetical double-digit leads against Johnson, Giannoulias seems better equipped to attract a wider range of voters. This suggests he could more effectively consolidate anti-Johnson sentiment across diverse demographic and geographic segments, including the critical lakefront and North Side wards, potentially building a more robust and resilient coalition than Vallas achieved.
8. What is the financial standing of Chicago mayoral candidates?
| Brandon Johnson Cash on Hand | $813,125 (April 2026 [^]) |
|---|---|
| Alexi Giannoulias Cash on Hand | $18.3 million (April 2026 [^]) |
| Fundraising Gap (Giannoulias vs. Johnson) | Approximately 22.5:1 [^] |
Mayor Brandon Johnson's campaign committee reported $813,125 in cash on hand as of April 2026 [^] . This amount represents the most current financial data available before any mandatory pre-election campaign finance disclosures for the Chicago mayoral election, which are anticipated in early 2027 [^]. These current reports provide an initial look at the financial landscape for potential candidates.
Illinois Secretary of State Alexi Giannoulias is currently identified as Mayor Johnson's best-funded potential challenger [^] . His campaign committee, Citizens for Giannoulias, held a significant $18.3 million in cash on hand as of April 2026 [^]. A comparison of these figures shows Giannoulias's reported cash on hand is roughly 22.5 times greater than Johnson's [^]. This substantial financial disparity significantly exceeds the threshold for a highly competitive race (less than 2:1), suggesting a considerable financial advantage for Giannoulias based on these current figures [^]. These financial positions are expected to change as the 2027 mayoral election draws closer [^].
