The Military Installation and Critical Infrastructure Protection Act of 2026 aims to bolster the security of agricultural land and critical infrastructure in Oklahoma by prohibiting foreign principals from foreign adversary countries from owning or controlling such properties. The bill specifically restricts these foreign entities from holding more than a 25% interest in agricultural land and requires them to divest any existing holdings within 180 days of the act's effective date. It also establishes registration requirements for foreign principals and invalidates any conflicting contracts or agreements. The Attorney General is empowered to enforce these provisions, including initiating judicial foreclosure for non-compliance and rewarding whistleblowers who report violations. Additionally, the act restricts foreign principals from purchasing or controlling real property within ten miles of military bases or critical infrastructure, with similar divestiture and invalidation requirements.

Moreover, the bill introduces strict regulations regarding software used in state infrastructure, prohibiting any software from federally banned corporations or foreign adversaries, including state-owned enterprises. Existing prohibited software must be removed and replaced with compliant alternatives, with state infrastructure providers exempt from additional permits for these changes, provided they notify the relevant state agency. The legislation also mandates the Office of the Attorney General to create a process for local and state officials to report concerns about non-notified transactions, with the Attorney General required to submit reports on these transactions to the Committee on Foreign Investment in the United States. The act is set to take effect on July 1, 2027.
