Billionaire Warren Buffett’s Berkshire Hathaway Dumps $42,867,000,000 in US Treasury Bills – Here’s One Stock He’s Just Piled Into

Warren Buffett has reduced Berkshire Hathaway’s stake in short-term Treasury bills by tens of billions of dollars and is doubling down on one broadcasting company’s stock.

New SEC filings show Buffett’s short-term Treasury bill holdings declined by $42.867 billion at the close of the second quarter of the year when compared to December 2024, with total holdings of T-bills now at $243.605 billion.

Meanwhile, Berkshire Hathaway purchased 5,030,425 more shares of Sirius XM Holdings (SIRI) last month at around $21 per share, bringing its total holdings of SIRI to 124,807,117 shares.

SIRI is trading for $20.97 per share at the close of the market on Wednesday.

Also last month, Berkshire Hathaway dumped nearly $1.23 billion worth of shares in the domain name giant Verisign.

Verisign announced the Omaha-based investment giant would sell 4,300,000 shares of the company’s common stock to the public for $285 per share. The sell-off materialized after Buffett’s firm acquired multiple new stocks in the first quarter of 2025.

Filings with the SEC earlier this year showed Berkshire added 865,311 shares of the swimming pool supply giant POOLCORP (POOL) for nearly $262 million in Q1. The firm purchased an additional 6,384,676 shares of the alcohol producer Constellation Brands (STZ) for nearly $961 million and it acquired 238,613 new shares of Domino’s Pizza (DPZ) worth approximately $204 million.

Berkshire also bought 112,401 new shares of Heico Corporation (HEI), an aerospace and electronics firm, worth nearly $50 million in Q1.
