Chicago is the third-largest city in the United States and one of the most economically diverse metro areas in the country. At an average AI Agent Preference Score of 34, it leads the six major markets we track, but leading a group that falls below Agent Ready still means no business in the metro is truly agent-compatible. 31% of Chicago service businesses are functionally invisible to AI agents.
Chicago scores higher than the other markets we track, reflecting slightly better adoption of web best practices among its large professional services sector. Law firms and dental practices in the Loop and North Shore suburbs tend to have more polished digital infrastructure than their counterparts in Phoenix or Houston.
Chicago's dense concentration of law firms, from solo practitioners in Wicker Park to large firms in the Loop, produces higher average web infrastructure scores. Legal services in Chicago average 41 on AI Agent Preference. But Transaction Completeness is near zero. An AI agent helping a user find a family law attorney in Chicago can identify firms but cannot initiate an intake or schedule a consultation on behalf of the user.
Chicago's dental market, especially in Naperville, Oak Park, and the North Shore suburbs, includes many practices that have invested in modern websites and patient portals. Dental practices here average 47, the highest vertical in the metro. But the gap is in the transactional dimensions, where Transaction Completeness scores sit near zero.
Chicago's large residential market and dense apartment stock drive strong demand for cleaning services. But the sector is fragmented across independent operators and small firms, most of whom have minimal web presence. Cleaning services average 38 in Chicago. Data Reliability and Transaction Completeness are the biggest gaps.
Chicago's brutal winters create predictable demand for auto repair. Despite that steady business, auto repair shops average just 35 on AI Agent Preference in the metro. The category has no meaningful transactional infrastructure. Even the larger multi-location shops in the Chicago suburbs score in the low teens.

Data reflects GradeForAI scoring of businesses with a Chicago metro service area. Scores are updated periodically as businesses change their web infrastructure.
Chicago's higher average score means the competitive dynamics are slightly different here than in Phoenix or Houston. More businesses have baseline web infrastructure. The race to agent readiness will be decided not by who has a website but by who builds the transactional layer on top of it. Transaction Completeness and Data Reliability are where Chicago businesses are losing ground to what agents need.
Chicago's technology sector, including major employers in fintech, healthcare tech, and enterprise software, means a large portion of the consumer base has been using AI tools for months or years. They will expect their AI agents to handle service bookings. The window to capture that traffic is open now, and the businesses that get agent-ready first will hold the position longest.
