The Chicago Bears' June 5 board vote to advance stadium plans in Hammond, Indiana—following the Illinois General Assembly's failure to pass a critical PILOT incentive bill—has pushed the "Yes" outcome near even money at 52.5%. Competitive balance stems from the team's continued ownership of the Arlington Heights site, ongoing legislative outreach in Springfield, and unresolved environmental and permitting questions at Wolf Lake and alternative Hammond parcels. Trader sentiment reflects uncertainty over whether final site selection and financing will lock in a cross-border move before year-end or allow a late Illinois compromise. A completed environmental study or new tax framework in Illinois could shift odds toward staying, while firm land acquisition and bonding authority in Indiana would strengthen the case for departure by December 31.
