Data Centre Debate Heats Up Ahead of US Midterm Elections 2026

Data centres are no longer just powering the internet. They are also becoming a major issue in the race for votes ahead of the US midterm elections on November 3. Across the country, Republicans and Democrats are facing growing opposition to these massive facilities. They power online banking, emails, web searches and artificial intelligence (AI) tools such as ChatGPT and Claude. However, concerns about rising electricity bills, water use and environmental damage are putting their expansion under pressure.

The scale of the data centre boom helps explain why the debate is growing. There are around 12,250 data centres worldwide, including 4,767 in the United States. The US also leads in installed capacity, at 53.73 gigawatts, compared with China’s 31.90 gigawatts. Meanwhile, technology companies are expected to spend about $765 billion on AI infrastructure in 2026. Spending could exceed $1 trillion in 2027, creating pressure for more construction. As new projects spread into rural areas, residents are increasingly questioning how these developments will affect their communities.

Voters Push Data Centres Into the Election Spotlight

Public opposition is becoming harder for candidates to ignore. A poll published in October found that 66% of Americans opposed building new data centres nationwide. Opposition rose to 72% when respondents were asked about a facility in their own community. Concerns also cross party lines. Another poll found that 69% of registered Democratic voters supported limits on construction, compared with 43% of Republicans. In addition, about 16 states have proposed laws to ban or temporarily pause new facilities.

Campaigns are responding with sharper attacks on the technology industry. More than 150 advertisements in the 2026 midterm election cycle have targeted data centres or AI. One Democratic ad branded Ohio Republican Derek Merrin ‘Data Center Derek’ over a $2 billion tax break. Meanwhile, at least 20 candidates for governor have called for temporary construction pauses. Republican Texas Senate candidate Ken Paxton has also called for slowing data centre expansion. Technology interests are spending heavily on the elections, with Elon Musk contributing $366 million to Republican causes. A pro-industry political group, Leading the Future, has raised more than $75 million.

Why Data Centre Rules Matter to Investors and Local Communities

The election debate is also creating uncertainty for Investors. Major technology companies, including Alphabet and Amazon, are investing heavily in AI infrastructure. Investors fear that new restrictions could delay projects, increase costs and affect expectations for future growth. A Democratic-led Congress could mean more hearings and investigations. However, analysts doubt that sweeping federal limits would become law. President Donald Trump has backed AI development and said companies should offer communities a financial benefit to help secure public support.

Morgan Stanley is monitoring governor races in Texas, Ohio, Pennsylvania, Georgia, Nevada, Wisconsin and Michigan. Its analysis identified 159 Texas projects, representing 24 gigawatts of capacity, as potentially exposed to restrictions between 2026 and 2030. State and local officials, including utility commissioners, can influence how quickly projects move forward. Supporters argue that data centres attract investment, generate tax revenue and create construction jobs. Ultimately, the midterm elections will test how the US balances AI ambitions with the concerns of people living near these facilities. The outcome could influence where data centres are built, how much they cost and how quickly America’s AI industry expands.
