Strategy Grows Bitcoin Stash to 818,869 With 535 BTC Buy

Strategy added 535 Bitcoin to its corporate treasury between May 4 and May 10, paying approximately $43 million at an average price of $80,340 per coin.

The acquisition, announced by Executive Chairman Michael Saylor on X, takes the company’s total holdings to 818,869 BTC as of May 10, 2026.

The purchase was funded through the company’s ongoing capital raise programs and continues the weekly buying pattern Strategy has held through most of 2026.

The latest purchase brings Strategy’s year-to-date BTC Yield to 9.44% and adds to a stack acquired for approximately $61.86 billion in cumulative cost basis.

Strategy’s Latest Bitcoin Purchase Adds 535 Coins

The 535 BTC purchase is one of the smaller ones Strategy has filed in recent weeks. The transaction was completed at an average price of $80,340 per coin, with the total outlay coming to roughly $42.98 million.

The purchase window covered the seven days between May 4 and May 10, with the filing dated May 11. Strategy has held to a weekly cadence of treasury purchases for most of 2026, with the size of each tranche tied to the cash raised by the company. The funds were raised through at-the-market equity programs, preferred stock issuances, and convertible note offerings during the same period.

The 535-coin figure follows a much larger 3,273 BTC purchase Strategy filed on April 27, when the company paid roughly $254.99 million at an average price of $77,906 per coin.

Before that, the company filed a 34,164 BTC purchase on April 20, the largest single tranche of 2026 to date at approximately $2.54 billion in total cost.

Saylor confirmed the purchase in a post on X, writing that the company had acquired 535 BTC for approximately $43.0 million at around $80,340 per coin. They had also achieved a BTC Yield of 9.4% year-to-date.

Holdings Cross 818,000 BTC and 3.9% of Total Supply

With the latest purchase, Strategy now holds 818,869 BTC across its corporate treasury, equal to 3.899376% of the total fixed supply.

The company has been the single largest corporate holder of the asset for several years and stays so by a wide margin.

The cumulative cost basis on the stack stands at approximately $61.86 billion, with an average cost of $75,540 per coin.

At the current price, the holdings carry a Bitcoin NAV of $66.52 billion, with the unrealized gain on the position running into the low single-digit billions of dollars.

Strategy’s metric for treasury performance, known as BTC Yield, came in at 9.44% year-to-date through May 10, with the quarter-to-date figure at 5.80%.

The measure tracks the change in Bitcoin held per diluted share, with the gain coming from purchases funded by share and debt issuance during the period.

The company’s BTC Gain year-to-date stands at 63,481.99 coins, with a dollar value of approximately $5.16 billion.

The quarter-to-date BTC Gain figure sits at 44,193.01 coins, equal to about $3.59 billion in dollar terms. Sats Per Basic Share now stands at 233,176, with Sats Per Diluted Share at 213,391.

Bitcoin Buying Pace Through April and May

Strategy’s pace of Bitcoin accumulation through April set the tone for the second quarter of 2026. The April 6 filing added 4,871 BTC at $67,718 per coin for $329.85 million.

The April 13 filing brought in 13,927 BTC at $71,902 for $1.00 billion. The April 20 filing then took 34,164 BTC at $74,395 for $2.54 billion in a single week, the largest weekly addition of the year so far.

The April 27 filing added 3,273 BTC at $77,906 for $254.99 million, with the May 11 filing closing the run at 535 BTC for $42.98 million.

The five purchases together added 56,770 BTC to the corporate treasury over five weekly windows, taking holdings from 766,970 BTC at the start of April to 818,869 BTC by the May 10 cut-off.

The cost-basis trend across the recent purchases moves with the overall Bitcoin price. Strategy paid $67,718 for the April 6 tranche, with the figure rising to $80,340 by the May 4 through May 10 window.

The five-week purchase average came in at approximately $73,335 per coin.

Earlier in the year, larger weekly purchases were filed in January and March. The January 20 filing added 22,305 BTC at $95,284 per coin, while the March 16 filing brought in 22,337 BTC at $70,194 and the March 9 filing took 17,994 BTC at $70,946.

Several smaller purchases of less than 1,500 BTC were filed across February as Bitcoin prices held in a tighter range before resuming larger purchases in March and April.

Stock Performance, NAV, and Debt Position

Strategy’s stock, which trades under the ticker MSTR, last closed at $187.59, up 4.31% on the session. The shares have gained 48.8% over the past three months, although the one-year return stays at negative 53.7%.

The total return since the company began the Bitcoin treasury strategy in August 2020 stands at positive 1,417.7%.

The company’s total market capitalization stood at $65.88 billion at the close of the latest session, with an enterprise value of $85.36 billion.

The NAV per basic share figure came in at $189.41, with the EV mNAV at 1.28x. The Bitcoin NAV figure sits close to the company’s market capitalization. This also places the stock close to par with the value of its underlying holdings.

On the balance sheet, Strategy had $8.21 billion in total debt outstanding and $13.52 billion in total preferred stock outstanding at the May 10 reporting date, for a combined $21.74 billion in fixed-income capital structure.

The Debt-to-Bitcoin NAV ratio stands at 0.12x, with the leverage ratio at 12.4% and the amplification ratio at 32.7%.

The size of the debt and preferred stack tracks the funding model Strategy has used to grow its Bitcoin holdings without diluting common shareholders beyond a controlled rate.

The company has run a mix of equity, preferred stock, and convertible debt issuances since the start of 2024. Also, the proceeds from each capital event went directly into weekly BTC purchases.

Total holdings now top 818,000 coins. Strategy is set to file the next weekly purchase update on or around May 18.

The firm’s buying cadence is holding through the May 10 cut-off, and the company is continuing to draw on its capital programs to fund the next tranche.
