Strategy Is Buying Bitcoin Again: 950 BTC This Week, 5,553 BTC Since the Pause Ended, and the MSCI Clock Ticking Toward October

Strategy (MSTR) bought 950 Bitcoin for $75.7 million at an average of $79,670 between September 14 and 20, 2026, according to a Form 8-K filed Monday, lifting holdings to 846,000 BTC acquired for $63.80 billion at an average cost of $75,416.

The purchase confirms that the summer pause is over. After roughly ten weeks without buying and two sales that ended its never sell era, Strategy added 4,603 BTC for $369.7 million in late August and has now bought 5,553 BTC across two purchases in a month.

The buying is running alongside an aggressive retirement of its own preferred stock: Strategy repurchased $174 million of STRC preferred last week and nearly $490 million over three weeks, after doubling its digital credit buyback authorization to $2 billion on September 8.

The company now sits on $5.04 billion in a reserve dedicated to dividends and interest plus $1.05 billion in deployable cash, and with Bitcoin near $86,000 its holdings show an unrealized gain of roughly $9 billion. MSTR jumped 7.4% in premarket trading on the news.

The MSCI consultation that could delete Strategy from its global indexes closes for feedback on September 30, with results expected around October 16 and any changes implemented at the November review, keeping an estimated $2.8 billion of forced passive selling on the calendar.

 

 

Strategy's filing on Monday was small by its own standards and significant for what it signaled. The company acquired 950 BTC for approximately $75.7 million during the week ended September 20, paying $79,670 per coin including fees, days before Bitcoin's breakout to $86,000. Its treasury now holds 846,000 BTC, roughly 4% of all Bitcoin that will ever exist, purchased for an aggregate $63.80 billion. At current prices near $86,000 the position carries an unrealized gain of about $9 billion.

How it paid is as telling as what it bought. The Bitcoin was funded from what Strategy calls USD Cash, the pool it maintains for general treasury purposes, rather than from new share sales; the company sold no stock through its at the market program during the week. That reflects the capital framework Michael Saylor introduced during the summer, which splits the balance sheet into a USD Reserve dedicated to preferred dividends and debt interest, now $5.04 billion after $57.4 million of payments last week, and a separate USD Cash account of $1.05 billion for Bitcoin purchases and capital management. Under the old model, every dollar raised went into Bitcoin; under the new one, Bitcoin competes with dividends, buybacks and reserves for the same cash.

 

 

The timeline corrects a popular narrative. Strategy stopped buying in late June, sold about $216 million of Bitcoin in July to fund preferred dividends and disposed of another tranche in August, when the pause reached seven weeks and holdings sat at 840,447 BTC. The first purchase after that stretch came in the week of August 24 to 30, when the company bought 4,603 BTC for $369.7 million at $80,318, financed by $369.7 million of MSTR share sales. Two quiet weeks followed, during which the company bought no Bitcoin but repurchased $176.3 million and then $139.3 million of its STRC preferred stock. Last week it did both, adding the 950 BTC while retiring a further 1,771,238 STRC shares for $174 million.

Taken together, Strategy has bought 5,553 BTC for about $445 million in a month and spent roughly $490 million buying back its own preferred stock in three weeks, after the board doubled the digital credit securities repurchase authorization to $2 billion on September 8. The picture is of a company managing its capital structure actively in both directions rather than a pure accumulation machine, and of a management team that resumed buying near $80,000 in the days before the market broke out.

 

Strategy's return removes one of the bear case's central arguments. Analysts partly blamed the summer pause for Bitcoin's muted reaction to good macro news in August, and the sales briefly turned the market's most famous buyer into a two way presence. With purchases resumed at scale and Bitcoin trading at eight month highs after absorbing a Fed hike and a CLARITY failure, the corporate treasury bid is back in the flow picture just as spot ETF demand recovers. MSTR shares responded with a 7.4% premarket jump to about $165, and crypto equities including Coinbase rallied alongside.

The framework does cap the enthusiasm. Purchases funded from USD Cash rather than equity raises are limited by the size of that account, now $1.05 billion, and the company has shown it will prioritize preferred buybacks when its securities trade at a discount. The old promise of buying every week regardless of conditions has been replaced by something more discretionary, which is healthier for the balance sheet and less reliable as a price floor.

 

None of this resolves the index question. MSCI's consultation on rules to identify non operating companies, which in the provider's own simulation would delete Strategy, Metaplanet and Yellow Cake from its global investable indexes, closes for feedback on September 30. Results are expected around October 16, with adopted changes implemented at the November index review. JPMorgan has estimated that exclusion could trigger roughly $2.8 billion of passive selling in MSTR alone, and earlier analysis put the figure as high as $8.8 billion if other providers follow. Strategy's public rebuttal, that index providers should measure markets rather than police corporate assets, has not changed the timeline. For the stock, the next month is a race between a strengthening Bitcoin bid and a possible forced seller in November; for Bitcoin itself, a deletion would test how much of the treasury narrative was ever priced in.

 

MSTR trades on the Nasdaq, but the story prices directly into BTC/USDT, where corporate treasury headlines have moved Bitcoin repeatedly this year, and it ripples into Ethereum (ETH) through treasury firms like Bitmine. Traders can set alerts around the September 30 consultation close and the mid October MSCI decision, watch Strategy's Monday 8-K filings as a weekly read on whether the bid persists, and manage event risk with MEXC Futures.
