Filings by Gregory B. Maffei span 12 companies, the busiest being Sirius XM Holdings Inc., Liberty Media Corp and Liberty Broadband Corp. Between 31 December 2015 and 26 August 2026, the trades on record add up to 100 filings.

In open-market terms, that means 1 purchase worth €937k on one side and 9 sales worth €544k on the other. Purchases outweigh sales by €392k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 55 share grants and 19 option exercises.

On 28 August 2026 came the latest disclosure, a share grant in Sirius XM Holdings Inc. The last purchase on record was published on 7 March 2022, which is 1,686 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
