A final buy to end the year
Strategy’s latest acquisition took place between December 22 and December 28, with the company spending roughly $108.8 million to add 1,229 Bitcoin to its treasury.
The coins were purchased at an average price of about $88,568 per Bitcoin, a level close to where the market was trading during the final days of the year.
With this transaction, Strategy’s total Bitcoin holdings climbed to approximately 672,497 BTC.
The company’s cumulative investment now runs into tens of billions of dollars, with an average cost basis estimated at just under $75,000 per coin.
That scale cements Strategy’s position as the largest corporate holder of Bitcoin globally.
MSTR stock slides amid Bitcoin bet
The market reaction to the latest purchase was mixed, with Strategy’s stock slipping following the disclosure of the purchase.
The stock is currently trading near its yearly lows even as the company expanded its Bitcoin position.
Although some may argue that the decline is a result of bitcoin price pullback, it also reflects ongoing investor unease about dilution and the broader performance of the stock in 2025.
However, some continue to view Strategy as a leveraged proxy for Bitcoin, arguing that sustained long-term appreciation in the asset could ultimately outweigh near-term stock pressure.
Betting on metrics, not moods
Strategy continues to point investors toward its internal performance measures, particularly a metric it calls “BTC Yield.”
This figure is designed to show how effectively the company increases Bitcoin holdings relative to its share count over time.
Strategy has highlighted a BTC Yield in excess of 20% for 2025, suggesting that, from its perspective, the strategy of issuing shares to buy Bitcoin is still delivering results.
The company has framed this approach as disciplined capital allocation rather than speculative trading.
For Michael Saylor, the year-end purchase fits a consistent narrative.
He has repeatedly argued that short-term price swings are secondary to building a large, permanent Bitcoin treasury and, ending 2025 with another nine-figure buy reinforces that message.
As the calendar turns, Strategy moves into 2026 with its largest Bitcoin (BTC) holdings to date, even as uncertainty lingers over how markets will ultimately respond.
