Sen. Elizabeth Warren (D-Mass.) is pressing for tighter oversight of the data center boom, arguing that tech giants shouldn’t unilaterally dictate where and how AI infrastructure gets built. “AI companies don’t get to call all the shots,” she said, calling for “leaders with the courage to stand up to tech companies.”
Her central worry is cost. Warren contends that data centers serving Big Tech drive up electricity bills for ordinary households, as utilities pass the expense of infrastructure upgrades on to consumers rather than the firms driving demand. She has previously flagged that AI facilities can consume electricity equivalent to more than 100,000 households.
The scale of expansion is enormous. U.S. tech companies committed to a record $850 billion in data center leases in the first quarter of 2026, with Meta ($META), Microsoft ($MSFT), and Oracle ($ORCL) leading the charge, alongside Amazon ($AMZN) and Google parent Alphabet ($GOOGL).
Warren wants communities to have a stronger voice in these decisions so that, as she put it, data centers “serve our communities, not just Big Tech’s bottom lines.”
Her concerns echo warnings from Mark Cuban, who has cautioned that the massive spending could expose venture capital and private equity investors to steep losses if the expected returns never materialize.
Together, the two critiques frame data centers as both a consumer-cost issue and a potential financial bubble worth watching closely.
