Illinois Climbs to No. 12 in CNBC Business Rankings

Illinois reaches its highest-ever position in CNBC's annual Top States for Business study, rising one spot to 12th nationally and marking an 18-place gain since 2019 — tied for the largest state improvement in the nation.

Lead

Illinois has reached its highest position in the history of CNBC's Top States for Business ranking, landing at No. 12 in the 2026 edition released July 9, up from No. 13 the prior year. The result extends what state officials describe as a seven-year Illinois economic revival, with the state having improved 18 spots since 2019 — a gain matched by no other state over the same window. CNBC scored all 50 states across 138 metrics in 10 competitiveness categories, with infrastructure carrying the heaviest weighting in the 2026 study.

What Happened

Illinois entered the 2026 survey ranked 13th, after spending much of the prior decade below the national median on the US state business climate index. The one-spot improvement to 12th, while incremental on its face, capped a multiyear structural rerating by CNBC's methodology — which balances factors ranging from GDP trajectory and budget health to workforce quality, education, cost of living, and physical infrastructure.

The state's strongest individual score came in infrastructure, where Illinois placed third nationally. CNBC also designated Illinois the country's top state for AI infrastructure, reflecting the density of data center development, power grid capacity, and broadband buildout concentrated in the Chicago metro and surrounding corridors. Infrastructure was the top-weighted category for 2026 as companies increasingly prioritize proximity to transportation hubs, utilities, and energy supplies capable of supporting advanced manufacturing and large-scale computing.

Illinois Business Ranking: Category Breakdown

The Illinois business ranking improvement reflects uneven but meaningful progress across CNBC's ten subcategories. Infrastructure at No. 3 provided the clearest lift. The economy subcategory — which accounts for credit ratings, budget revenues and expenditures, and GDP growth — improved to No. 29 in 2026, up from No. 45 when the current administration took office in 2019.

Workforce remains the state's sharpest vulnerability. Illinois placed 31st in that category, a lagging indicator that encompasses labor force participation, educational attainment, and skills alignment with employer demand. That drag has constrained Illinois from breaking into the top ten despite infrastructure and economy gains.

Illinois has directed roughly $50.6 billion toward infrastructure through successive capital programs, including the Rebuild Illinois initiative, which has funded road and bridge repair, transit modernization, airport upgrades, rail improvements, and rural broadband expansion. State officials tied that investment directly to the No. 3 infrastructure ranking and to the AI infrastructure designation, as power-intensive data center operators have cited grid reliability and fiber density as location determinants.

CNBC Top States for Business: National Picture

At the top of the CNBC top states for business 2026 table, Ohio claimed the No. 1 position for the first time in the study's history, which dates to 2007. Ohio's ascent — it ranked 30th in the inaugural study — was driven by the nation's leading infrastructure score and competitive business costs. North Carolina, which held the No. 1 spot in 2025 and has finished first or second in each of the past six years, placed second in 2026, missing a repeat by nine points.

The methodology shift toward infrastructure as the dominant weighting proved consequential across the rankings. States with significant logistics networks, industrial power capacity, and broadband penetration generally outperformed peers with stronger workforce scores but thinner physical plant.

Strategic Context

The Illinois economic revival narrative carries political as well as economic significance. The state carries high unfunded pension obligations and has historically ranked near the bottom of business climate surveys conducted by groups emphasizing tax burden and regulatory environment. The CNBC ranking, which weights infrastructure and quality-of-life factors heavily alongside cost measures, has tracked a different trajectory — one that state economic development officials have actively used in corporate relocation and site selection conversations.

The AI infrastructure designation adds a forward-looking dimension. Data center investment in the Chicago metropolitan area has accelerated as hyperscale operators seek cooling-capable geography, diversified power sourcing, and low-latency connectivity to Midwest financial and industrial markets. If that investment continues, Illinois's infrastructure score could provide further upside in future rankings editions.

Outlook

Illinois's rise to 12th in the CNBC top states for business 2026 study marks a decade-high in the state's competitive standing and validates a sustained infrastructure investment strategy. Closing the workforce gap — currently ranked 31st — represents the clearest path to further improvement in the study's scoring model. With Ohio's infrastructure-led formula now atop the national rankings and infrastructure retaining its top weighting in CNBC's methodology, Illinois is positioned to press its AI and logistics infrastructure advantages in near-term site selection competition. Whether pension obligations and cost-of-living headwinds resurface as limiting factors remains the central variable in the state's longer-term US state business climate trajectory.
