About Illinois

Illinois's Form D filings concentrate in Chicago, which remains one of the US's top-5 tech and finance metros by filing volume. Chicago hosts mature fintech (trading infrastructure, payments, insurance-tech), enterprise SaaS, logistics and supply-chain tech, food-and-beverage, and healthcare companies. The University of Chicago and Northwestern research ecosystems produce biotech and AI/ML filings. Chicago's derivatives and trading industry (CME Group, Citadel, DRW, Jump, Optiver) generates distinctive quant-finance and trading-infrastructure filings. Round sizes span the full range — from small seed rounds to $200M+ growth rounds. Delaware incorporation is universal; Illinois LLCs appear for real-estate vehicles.

In 2026, Illinois accounts for 171 catalogued filings totaling $5375.6M, running at roughly 39.0 filings per week over the last 30 days.

About private capital in Illinois

Illinois has high corporate and personal income tax rates and complex state regulation, which has driven some operating-company and fund-manager relocation in recent years (particularly to Florida and Texas). However, Chicago's capital-markets infrastructure, talent depth, and customer concentration maintain the city's position as a major Form D filing origin. The Chicago financial-services cluster generates high-volume fund-vehicle and SPV filings — private-equity and hedge-fund managers continue to operate from Chicago despite some competitive pressure from lower-tax states. Chicago real-estate vehicles target Midwest commercial and multifamily assets. Operating companies incorporate in Delaware as standard.

Illinois funding trends

Recent Illinois Form D filings show several patterns. First, Chicago fintech and trading-infrastructure companies file regularly at mid-to-large stages. Second, logistics-tech and supply-chain companies tied to Chicago's transportation-hub economy appear steadily. Third, healthtech and AI/ML filings from the university-ecosystem spinouts contribute meaningfully. Fourth, private-equity and hedge-fund SPVs are high-volume. Fifth, CPG and consumer-brand companies file from Chicago addresses. Sixth, real-estate vehicles target Midwest assets. Illinois sits reliably in the top filing states.
