MicroStrategy (MSTR), the world’s largest publicly traded holder of Bitcoin, bolstered its BTC portfolio in the latest week, capitalizing on a significant price rebound and renewed investor confidence.

The company announced acquiring 4,980 Bitcoin (BTC) for approximately $531.1 million during the period ending Sunday, details revealed in a Monday filing with the U.S. Securities and Exchange Commission (SEC).

BTC surged approximately $7,000 during the week, rising from around $101,000 on June 23 to exceed $108,000 by the close of the week, according to CoinGecko data. The acquisition’s average price per coin stood at approximately $106,800.

With this latest purchase, MicroStrategy’s total Bitcoin holdings increased to 597,325 BTC, acquired primarily in chunks ranging from $31.3 million to $80 million per transaction initiated by Michael Saylor. The overall cost basis for its Bitcoin investments is estimated at $42.4 billion, averaging about $70,982 per coin.

MicroStrategy YTD Bitcoin Gains Hit $9.5 Billion

As of Monday, MicroStrategy’s year-to-date (YTD) Bitcoin gains total 85,871 BTC, equivalent to roughly $9.5 billion. This significantly exceeds the $13 billion ($140,538 BTC) accumulated by the company throughout the entirety of 2024.

The company’s YTD Bitcoin yield rose slightly by 0.5 percentage points to 19.7%, bringing it closer to Saylor’s previously stated target of 25% of the company’s market cap returning from its Bitcoin holdings by the year’s end. The quarter-to-date BTC yield also edged up by 0.4 percentage points to 7.8%.

Surprise crypto capital transfer noted by analysts

The timing of MicroStrategy’s Bitcoin purchase was consistent with CEO Michael Saylor’s recurring suggestions of purchases made each Sunday. However, analysts also observed the company moving a substantial amount of BTC shortly after the filing.

On Sunday, Blockchain analytics firm Lookonchain detected the transfer of 7,383 BTC, valued at approximately $796 million, to three newly created wallets. Lookonchain suggested this “likely for improved custody.”

Saylor Reflects on Early Bitcoin Bet

Prior to sharing the latest purchase figures on X, Saylor shared his foundational Bitcoin narrative, reposting a 2020 interview with RealVision founder Raoul Pal. In that interview, he detailed the decision to make “Bitcoin the focus of everything,” initiated by MicroStrategy in August 2020.

“…I’m buying it for the dude that’s going to work for the dude that’s going to get hired by the guy who takes over my job in 100 years. I’m not selling it. When it goes up by a factor of 100, I might be borrowing a little to go buy something that I want, but what am I going to buy with it that’s better than what I’m buying?”

This articulation highlights what Saylor has consistently framed as a long-term, foundational belief in Bitcoin rather than speculative trading.
