HydraVault, an AI data center, has commenced construction in Chicago's South Loop, transitioning from an originally proposed esports arena. The city classified this change as 'minor,' bypassing public hearings.

Local residents express concerns regarding transparency, particularly about water and energy usage. The center is marketed as a sustainable facility aiming to reduce environmental impact. Governor Pritzker's recent proposal to pause new tax incentives for data centers highlights rising scrutiny over resource consumption, with potential legislation on data center accountability introduced in Illinois. Construction is expected to be completed by December 2026.
