As Mayor Brandon Johnson faces mounting pressure over the $9 billion Quantum Shore Chicago megadevelopment, community advocacy organizations are demanding an immediate halt to the 128-acre quantum computing campus planned for the former U.S. Steel South Works site on the city’s Southeast Side.
The Clash at Arnold Mireles Academy
On Saturday, August 15, 2026, Mayor Johnson attended the “Community over Quantum” town hall hosted by Southside Together at Arnold Mireles Academy, located at 9000 S. Exchange Ave. The event drew intense pushback from local residents and Southeast Side neighbors concerned about the massive project’s environmental and infrastructural impact.
According to reports from Block Club Chicago, attendees chanted slogans like “Reverse the permits. Shut it down. Mayor Johnson, do it now.” Despite the vocal opposition, Johnson stopped short of reversing his support or committing to halt the development.
Instead, the mayor pointed to a recent executive order designed to strengthen procurement and regulatory processes for data centers across Chicago. “Here are my values: That innovation cannot take place at the expense of environmental justice, that … development cannot happen at the expense of utilities and working people, and that private investment cannot happen at the expense of our overall public health,” Johnson stated during the town hall.
Project Scope and Hyperscale Infrastructure
The controversy centers on the Illinois Quantum and Microelectronics Park, a proposed 128-acre commercial hub led by development firm Related Midwest. Related Digital announced in March 2025 that it planned a hyperscale data center for AI and cloud computing situated at the northern end of the broader Quantum Shore campus.
The campus serves as a testing ground for practical quantum computing. Private entities including PsiQuantum, IBM, and Infleqtion, alongside the federal Defense Advanced Research Projects Agency and multiple Illinois universities, are slated to participate in the research initiative.
Financial backing for the megadevelopment draws from multiple public and private sources. Local leaders noted last year that the campus is estimated to cost $9 billion. Public funding commitments include $500 million from the state, an estimated $175 million in county tax breaks over 30 years, and a $5 million pledge from Chicago’s housing and economic development bond program authorized by Johnson.
Community Backlash and Political Divisions
While the project has secured backing from prominent officials—including Gov. JB Pritzker, Cook County Board President Toni Preckwinkle, Ald. Peter Chico (10th), Ald. Greg Mitchell (7th), and Mayor Johnson—local resistance remains fierce.
During Saturday’s town hall, Southside Together member Lia Terrell criticized the administration’s reliance on regulatory executive orders rather than outright cancellation. After Terrell denounced the mayor’s stance, Johnson departed the event amid jeers and boos from the audience.
“The reality is that we don’t have the mayor’s support,” Terrell said at the event. “The data center executive order is not the same thing as stopping the quantum facility, which means he doesn’t support the needs of the people in the community, and he doesn’t respect the needs of Chicago as a whole. He’s chosen to stand on the side of military-backed billionaires.”
Opponents continue to argue that the massive campus introduces significant environmental risks and utility strain to South Chicago, leaving the future of the Quantum Shore initiative politically contested as local advocacy groups press for a complete reversal.
