Sen. Tina Smith reported selling as much as $250,000 worth of BRKB, the Class B shares of Berkshire Hathaway, according to a newly filed congressional transaction disclosure covering trades made at the end of March.
The Minnesota Democrat disclosed that the position—held by her spouse—was partially or fully sold on March 31, 2026. The filing lists the transaction in a broad disclosure band of $100,001 to $250,000, a range commonly used in congressional financial reports required under the STOCK Act.
Based on the midpoint of the disclosure range, the transaction’s approximate value would be around $175,000. Members of Congress are required to report trades within 45 days, but the rules allow them to disclose only value ranges rather than precise figures.

Berkshire Hathaway, the sprawling conglomerate long led by Warren Buffett, is one of the most widely held stocks among U.S. investors. The company owns or holds major stakes across insurance, railroads, energy, manufacturing, and consumer brands, making its shares a common portfolio anchor for diversified investors.
Smith’s filing does not specify the exact number of shares sold or the precise proceeds from the transaction. Congressional financial disclosure rules only require lawmakers to report trades within predetermined ranges, which can obscure the exact size of an individual transaction.
A relatively limited trading history
Smith has reported 41 stock trades during her congressional career, according to compiled public filings. That places her well below some of the most active traders on Capitol Hill, where certain lawmakers have disclosed hundreds of transactions over the same period.
The senator serves on several influential committees, including the Senate Committee on Agriculture, Nutrition, and Forestry; the Senate Committee on Banking, Housing, and Urban Affairs; the Senate Committee on Finance; and the Senate Committee on Indian Affairs. Berkshire Hathaway’s diversified holdings span industries from insurance to transportation and energy, though none of Smith’s committees directly oversee the conglomerate itself.
Still, the breadth of Berkshire’s operations means its performance is tied to multiple sectors that frequently intersect with federal economic policy debates, including infrastructure, financial markets, and taxation.
Berkshire trades appear across Congress
Smith is not the only lawmaker to report transactions in Berkshire Hathaway shares. At least 10 members of Congress have disclosed trades involving BRKB in recent years, according to public financial filings.
The company’s reputation for long‑term stability and its exposure to a wide range of industries often make it a staple holding in diversified portfolios—including those held by lawmakers and their families.
Under the 2012 STOCK Act, members of Congress and their immediate families must publicly disclose most securities transactions. Those filings allow the public to monitor potential conflicts of interest and track latest congressional trades as they are reported.
Smith’s March 31 sale adds another Berkshire transaction to that growing public record, though the disclosure leaves open key details such as the exact share count and the final proceeds from the trade.
