American Bitcoin Corp. has expanded its bitcoin reserve to 4,783 BTC as of Dec. 8, according to new disclosures from the company published Wednesday. The increase includes 416 bitcoin added since its previous update on Dec. 2, with the firm highlighting that its total holdings account for both mined and strategically purchased bitcoin (BTC).

The filing also reaffirmed the company’s focus on transparency with its Satoshis Per Share (SPS) metric, which tracks the amount of bitcoin tied to each outstanding share. As of Dec. 8, the metric stood at 507 satoshis per share after climbing more than 17% from Nov. 5. “With our bitcoin reserve now at 4,783, we continue to scale at an exceptional pace,” Eric Trump, the company’s co-founder and chief strategy officer, said in the release.

Trump added that the company has “built one of the largest and fastest growing bitcoin accumulators” since its Nasdaq listing roughly three months ago, citing its cost structure and margin considerations as part of that progress. He noted the company intends to maintain its momentum in the months ahead. On X, Trump chimed in a few days ago about ABTC climbing the ranks in the bitcoin treasuries arena, giving the company a bit of spotlight as it edged closer to the next milestone.

He pointed out that Gamestop, the publicly traded company dabbling with BTC on its balance sheet, was the next one American Bitcoin would overtake. “Next: Gamestop,” Trump said at the time. Now, based on figures compiled by bitcointreasuries.net, ABTC has officially stepped ahead of Gamestop following its latest bitcoin addition.

Despite the increase in reserves, ABTC’s stock has not followed the same trajectory. According to figures published by bitcoinminingstock.io, the company’s shares are down more than 2% on the day, more than 11% over the past week, and over 50% in the past 30 days.

The divergence between treasury growth and share price performance reflects broader investor caution in the mining and accumulation segment, which has seen uneven trading in recent weeks. While it is the 22nd largest corporate holder of bitcoin, ABTC is the 11th largest publicly traded miner in terms of market cap.

The company said on Wednesday that it will continue providing reserve and SPS updates through its website and social channels, where it expects to publish additional metrics, treasury changes, and future communications.
