Should members of Congress be allowed to own stock in companies they oversee through legislation?

Twenty-six U.S. senators collectively hold at least $7 million in investments linked to data center development. These figures were identified through an analysis of 2025 financial disclosures.

Why it matters

Senators hold positions that influence legislation on data center siting and utility billing responsibilities. This creates potential overlap between congressional oversight and personal financial interests in the infrastructure sector.

Investment exposure includes holdings in companies like NVIDIA and Amphenol, which have seen stock increases of approximately 1,000% and 350% respectively over the last five years. The total minimum investment across the identified group of senators is $7 million.

The players

Sheldon Whitehouse

Senator from Rhode Island who holds between $2.1 million and $8.6 million in data center-linked investments.

Alan Armstrong

Senator from Oklahoma appointed in March 2026 who holds between $1.8 million and $7.5 million in data center-linked investments.

Ron Wyden

Senator from Oregon who holds at least $1.3 million in data center-linked investments and proposed tax legislation.

Bill Hagerty

Senator from Tennessee who holds between $500,000 and $1 million in data center-linked investments.

Susan Collins

Senator from Maine who holds between $300,000 and $800,000 in data center-linked investments.

The details

Forbes scraped 2025 financial disclosures and recent filings to identify assets connected to the expanding data center ecosystem. A reporter then manually vetted these investments to isolate companies primarily involved in the physical buildout and critical component supply chain for these facilities. This includes manufacturers of high-performance connectors and hardware essential for scaling computing power.

2021: Susan Collins supported a data center proposal in Maine.
2025: Senators filed the financial disclosures used for this analysis.
March 2026: Alan Armstrong was appointed to the Senate.
August 2026: Ron Wyden proposed legislation regarding data center taxes.
September 30, 2026: Bill Hagerty spoke on the Senate floor regarding infrastructure.

The Tech Race

The findings sit within the context of the STOCK Act and the ongoing debate over congressional financial transparency. This analysis highlights how individual legislative influence now intersects with the rapid scale-up of physical computing infrastructure.

The public remains skeptical of this expansion, with 66% of Maine residents and two-thirds of Americans overall opposing new data center construction in their communities. These investment disclosures provide citizens a direct view into the financial interests held by lawmakers governing this local infrastructure.

The takeaway

Public sentiment remains firmly against the rapid expansion of physical data centers, contrasting with the high-growth financial performance of firms supporting them. Citizens can monitor future legislative sessions to see if the proposed tax and siting bills influence the value of these disclosed assets.
