American Bitcoin (ABTC), backed by the Trump family, increased its total Bitcoin (BTC) holdings to more than 7,500. That made it the world’s 15th-largest holder among publicly traded companies.

BeInCrypto, a blockchain media outlet, reported on May 18 that Strategy also bought additional Bitcoin worth about $2.01 billion over the same period, extending companies’ Bitcoin treasury strategies.

The two companies’ disclosures show listed firms continued accumulating Bitcoin last week. Bitcoin prices were about 5 percent lower than the previous week, but buying continued. American Bitcoin shares fell 8 percent on the day to a record low.

American Bitcoin was co-founded by Eric Trump (에릭 트럼프) and Donald Trump Jr (도널드 트럼프 주니어). The company debuted on Nasdaq after a share-swap merger with crypto mining firm Hut 8 (Hut8) in September last year and has rapidly increased its Bitcoin holdings. The company said its Bitcoin reserves have more than tripled since listing, and satoshis per share rose above 700, more than doubling from the time of its listing.

Eric Trump has also publicly rebutted questions raised about the company’s business model. That trend renewed market interest in digital asset businesses linked to the Trump family.

Strategy bought 24,869 BTC last week at an average purchase price of $80,985. Its total holdings rose to 843,738 BTC, with holdings valued at $63.87 billion and an average acquisition cost of $75,700. Its BTC yield since the start of 2026 was 12.6 percent.

The purchases were funded through the STRC perpetual preferred stock programme. Strategy raised $1.95 billion by issuing 19.5 million shares and used the funds to buy 24,066 BTC at about $81,000, the disclosure showed. That was the second-largest weekly fundraising amount on record for STRC.

The market had also focused on the possibility that Strategy could sell Bitcoin before the end of this month, but it has been confirmed there has been no sale so far. On prediction market Polymarket, the probability that Strategy would sell at least some Bitcoin by the end of this month was priced at 41 percent, but the company’s disclosures put more weight on expanding holdings.

Strategy currently accounts for about three-quarters of corporate-held Bitcoin and is moving toward a goal of securing 1 million BTC. While Strategy continues buying through large-scale fundraising, American Bitcoin is building its presence by citing a faster growth rate. Its stock falling to a record low also shows the gap between expanding Bitcoin holdings and shareholder value.

Ultimately, last week’s corporate Bitcoin accumulation continued to be driven by large holders. But as broader treasury demand among smaller companies has slowed in 2026, the market has entered a phase of watching both large holders’ capacity for additional purchases and their ability to defend share prices.
