As of Nov. 13, 2026, voters have decided on 47 ballot measures related to data centers throughout the year, with 46 (98%) limiting their development and one (2%) favoring it.

In December, they will decide on four more across three states: Arkansas, Maine, and North Dakota.

Arkansas

On Dec. 1, 2026, voters in Clarksville, Arkansas, will consider two measures related to the financing for the development of a data center owned by Serverfarm:

• The first ballot measure would uphold an ordinance that authorized up to $50 billion in taxable industrial development bonds to finance data center equipment and improvements, leasing the project to Hatchbo LLC, and authorizing an agreement for payment in lieu of taxes.
• The second measure would uphold an ordinance authorizing up to $5 billion in taxable industrial development bonds to finance land acquisition for data center operations, lease the project to SF ARK1, LLC, and authorize an agreement for payment in lieu of taxes.

The Clarksville City Council initially approved two ordinances for both projects in July, with residents submitting 425 signatures to put each measure for a referendum vote. While the measures are about the project's bond financing, they are not a direct vote on whether the data center will be built.

A simple majority vote is required to approve each measure.

Maine

On Dec. 8, 2026, voters in Hollis, Maine, will weigh in on the following measure:

• Article 2 would establish a 180-day moratorium, beginning Dec. 8, 2026, on new or expanded data centers with at least 2,500 square feet of data center area, including associated impervious surfaces such as access roads and parking lots.

While the proposed moratorium had an original threshold of 25,000 square feet, the Hollis Select Board voted to lower the threshold to 2,500 on Nov. 4, 2026.

A simple majority is required for its approval.

North Dakota

On Dec. 15, 2026, voters in Mandan, North Dakota, will decide the following measure:

• Measure 1 would prohibit both large-scale and multiple data centers within the city and its territories that would have an aggregate amount of electrical demand of 25 megawatts or more.

The measure is in response to a planned data center from Stark Power, a company that develops such facilities. However, construction has not begun, and it still must go through the city planning and approval process.

A simple majority is required for its approval.
