Bitcoin Treasuries Grow as Saylor’s Strategy, Trump-Linked American Bitcoin Add to Holdings
27/10/2025

Corporate Bitcoin accumulation is showing no signs of slowing. Two of the space’s biggest players — Michael Saylor’s Strategy (MSTR) and American Bitcoin Corp. (ABTC) — both increased their BTC reserves this week.

American Bitcoin purchased 1,414 BTC, bringing its total stash to 3,865 BTC as of October 24. The firm also introduced a new transparency metric, Satoshis Per Share (SPS), giving investors a clearer view of their per-share Bitcoin exposure.

Strategy added 390 BTC for $43.4 million at an average cost of $111,053, pushing its total holdings to 640,808 BTC — worth roughly $71 billion. The company’s year-to-date Bitcoin performance stands at +26%, continuing its dominance as the largest corporate BTC holder globally.

American Bitcoin — born from a merger between Gryphon Digital Mining and American Data Centers, a venture linked to President Trump’s sons — listed on Nasdaq in September. Its stock rallied more than 10% to $6.20 on Monday, while MSTR gained nearly 2%.

Both companies benefited from Bitcoin’s rebound above $115,000, capping a volatile but bullish start to the week.
