Warren Buffett’s Berkshire Hathaway has increased its stake in Sirius XM, purchasing an additional 2.3 million shares for about $54 million. According to a filing with the SEC, the transactions took place from Thursday through Monday. This move brings Berkshire Hathaway’s ownership in the satellite radio company to 35.4%.
Berkshire began investing in Liberty Media’s trackers in 2016. In early 2024, the company ramped up its Sirius XM acquisitions, likely as a merger arbitrage play. John Malone’s Liberty Media recently combined its tracking stocks with the rest of Sirius XM’s assets to significantly reorganize Malone’s media empire.
Warren Buffett has yet to comment publicly on the Sirius XM investment.

It remains unclear whether Buffett himself, his investment managers Ted Weschler and Todd Combs, or both were involved in the decision.
Berkshire Hathaway also acquired approximately five million shares of Sirius XM in December 2024. Sirius XM experienced a challenging 2024, with shares plummeting 58% due to subscriber losses and unfavorable demographic trends. The stock has seen a modest recovery, rising about 5% since the beginning of 2025.
Despite these gains, Sirius XM remains underappreciated on Wall Street, with only three out of 16 analysts giving it a buy rating, according to data from FactSet. The latest acquisition underscores Berkshire Hathaway’s continued strategic investments and reinforces its significant interest in media and entertainment ventures.
