Michigan received $1.6 billion in federal BEAD funding. The Michigan High-Speed Internet Office is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.
