Michael Saylor's Strategy Just Dropped Another $143 Million on Bitcoin — Its Stack Just Hit a Mind-Bending Record

Michael Saylor is at it again. Strategy — the company that turned buying Bitcoin into a corporate strategy — has scooped up another 1,665 BTC for roughly $143 million, pushing its total stash to 847,666 Bitcoin. That's a new all-time record for the firm, and it means one company now controls more than 4% of every Bitcoin that will ever exist.

The purchase, disclosed in a September 28 filing with the U.S. Securities and Exchange Commission, shows Saylor's conviction hasn't wavered one bit — even with Bitcoin trading in the low $80,000s and markets rattled by oil prices, soaring bond yields, and US-Iran tensions.

The numbers behind the buy

According to the 8-K filing, Strategy acquired the 1,665 Bitcoin at an average price of $85,681 per coin during the week of September 21–27. The company has now spent approximately $63.95 billion on its holdings, including fees and expenses, at an average purchase price of $75,437 per Bitcoin.

At Bitcoin's recent price near $83,700, the 847,666-coin stack is worth around $71 billion — more than 4% of Bitcoin's hard-capped 21 million supply. Roughly one in every 24 Bitcoin in existence now sits in Strategy's wallets.

The buy surpasses the firm's June holdings record, restoring the stash after a summer in which it sold 6,948 BTC — a rare pause in Saylor's famously relentless accumulation.

How Saylor pays for it

Strategy doesn't buy Bitcoin with spare cash from a software business — it funds the spree by selling its own stock. Last week the company sold about 1.47 million MSTR shares, generating $246.2 million in net proceeds. Of that, $142.7 million went to Bitcoin and $103.5 million supported repurchases of its STRC preferred stock.

The firm also deployed $48.1 million from its USD cash balance toward a total $151.7 million STRC buyback, while using $22.1 million of its USD reserve to pay preferred-stock dividends. After all the moving parts, Strategy's USD reserve sits at $5.02 billion and its USD cash at $1 billion — a war chest that lets it keep buying, keep paying dividends, and keep repurchasing stock at the same time.

It's an "active capital management framework," in the company's words: issue equity, buy Bitcoin, manage the preferred dividends, repeat. As of September 27, another $18.84 billion worth of MSTR shares remain available for issuance — the machine has plenty of fuel left.

Buying the dip — or catching a falling knife?

The timing is classic Saylor. Bitcoin slid below $84,000 on Monday as Treasury yields hit their highest level since 2007 and traders priced in a greater than 70% chance of another Federal Reserve rate hike in October. Over $530 million in crypto positions were liquidated in 24 hours, mostly overleveraged longs getting wiped out.

While retail traders were getting flushed, the biggest corporate buyer on the planet was doing what it always does: buying. The week before, Strategy had already picked up 950 BTC for $75.7 million after a two-week pause. The message to the market is unmistakable — Saylor treats every pullback as inventory restocking.

Prediction-market traders put just a 7–8% chance on Strategy reaching 1 million BTC before 2027 — closing that gap would take roughly $12.7 billion at current prices.

What it means for the market

Love it or hate it, Strategy has become crypto's most important single buyer. When the largest corporate holder keeps accumulating through macro fear — oil above $105, yields at 19-year highs, war-risk headlines — it sends a signal that institutional conviction in Bitcoin as a treasury asset isn't cracking.

Whether $85,681 turns out to be a brilliant entry or an expensive top, one thing is certain: nobody moves the Bitcoin market's psychology quite like the orange dot on Saylor's tracker turning a little bit bigger.
