Civic/Governance Barriers activates on moratorium-class action (C1), litigation/recall pathway (C4) — governance instruments on the electoral, legislative, and regulatory surface (protocol §10; Overview Civic breakout). Energy/Power dominant (xAI's Southaven turbines are a potential top-3 U.S. NOx source; Amazon/Entergy grid buildout). Capital Flows is a secondary stressor: Mississippi law removed the 4% rate cap and pre-approval requirements for Amazon-related spend and lets Entergy recover costs pre-service, with reports of likely rate increases already — a clear ratepayer cost-shift vector (DeSoto County News). Water/Geology raised in Jackson/Clinton zoning (though Clinton's Amazon site claims zero water use) (SuperTalk).

None identified. Mississippi's 2026 U.S. Senate race (Cindy Hyde-Smith, R) and other races have not surfaced data centers as a defining campaign issue in coverage reviewed; the action is legislative/litigation/local rather than candidate-driven.

No statewide moratorium (state policy is pro-development). Multiple local actions: Jackson tabled a proposed six-month moratorium but signaled no data centers will proceed until regulations are in place (Spot On Mississippi); Jackson County passed a 180-day moratorium on data-center applications (WLOX/YouTube); the City of Clinton amended zoning to require conditional-use permits and industrial-only siting for data centers (WJTV/YouTube).

State law is largely permissive/pro-development: a Mississippi law tied to the Amazon projects lets Entergy begin cost recovery before facilities are in service, waives prior commission approval for related spending, and removes the 4% annual rate-increase cap for Amazon-related spending — a report by environmental nonprofits suggests the Amazon data centers have likely already raised Entergy Mississippi rates (DeSoto County News). The standing data-center incentive program (since 2019) exempts certified companies from state sales/use, corporate income and franchise taxes for 10 years, and xAI's $20B Southaven campus qualifies (The Local Voice). No 2026 ratepayer-protection statute identified.

None identified. No Mississippi November 2026 data-center ballot measure surfaced in current coverage of the state's projects and local fights (DeSoto County News).

xAI Southaven power plant / Colossus 1 & 2 (South Memphis, TN): the centerpiece contested site. The NAACP and Mississippi State Conference NAACP sued xAI and subsidiary MZX Tech in April 2026 in the U.S. District Court for the Northern District of Mississippi over 27+ (later 57-59) unpermitted gas turbines allegedly violating the Clean Air Act (NAACP). Separately, three DeSoto County residents filed a class action (June 8-9, 2026) against xAI, SpaceX and MZX Tech over 'near-constant' turbine noise/vibration on behalf of 10,000+ residents (Mississippi Free Press). Amazon campuses in Clinton, Canton, Madison and Vicksburg ($3B) (SuperTalk; DataCenterDynamics Vicksburg).

Boosters emphasize construction/operations jobs from Amazon and xAI investment, but no distinct labor-organizing or displacement fight identified; included as secondary context (SuperTalk).

Growing: seven projects in the works as of mid-2026 (up from two in early 2025), including xAI Southaven ($20B), four Amazon campuses (Clinton, Canton, Madison, Vicksburg) and a proposed Jackson project by Saxum Investment (DeSoto County News; DataCenterDynamics AWS).

"It is a textbook example of putting profits over people, with corporate interests trampling residents' fundamental right to use and enjoy their property." — from the DeSoto County residents' class-action complaint against xAI (Mississippi Free Press)
