Berkshire keeps buying SiriusXM stock
The move
Berkshire Hathaway bought 924,281 more shares of Sirius XM Holdings (SIRI) over three trading days — 743,965 on Oct. 30, 66,968 on Nov. 2 and 113,348 on Nov. 3 — at weighted-average prices from $28.89 to $30.23, an SEC Form 4 shows. The purchases bring Berkshire's stake to 125,731,398 shares, held through GEICO and Berkshire subsidiaries' pension plans.
Why it matters
Berkshire has been one of SiriusXM's largest and steadiest buyers since the Liberty Media tracking-stock split, and each purchase adds to an already large position.
The bear case
SiriusXM has lost subscribers in recent years, so a bigger stake also means bigger exposure if that trend continues.
What to watch
Berkshire's next Form 4 filings and its Q3 2026 earnings, expected this month.
