• MicroStrategy purchased another $4.6 billion worth of bitcoin last week.

• The company's total bitcoin holdings are now worth roughly $30 billion.

• MicroStrategy sold around 13.6 million shares to fund the most recent bitcoin purchase.

• The company adopted a bitcoin reserve strategy in 2020 and their open-source plan has been used as a blueprint for other publicly traded companies that have purchased the crypto asset.

MicroStrategy (MSTR) made a massive addition to its bitcoin (BTCUSD) holdings over the past week. Over the six days ending on Sunday, the technology company acquired 51,780 BTC for approximately $4.6 billion, according to a recent regulatory filing.

This purchase boosts its total bitcoin holdings to 331,200 BTC, which is worth roughly $30 billion at current prices. Notably, this is still far less than the 471,329 bitcoin held by BlackRock's iShares Bitcoin Trust (IBIT), which is the largest bitcoin exchange-traded fund (ETF).

MicroStrategy shares were up 8.6% to $370.11 in recent trading and have seen their value quadruple (increase over 440%) year-to-date. Meanwhile bitcoin was trading above the $91,000 level Monday, and has almost doubled in price since the start of the year.

MicroStrategy’s latest acquisition comes as bitcoin continues to surge, with the price recently spiking above $90,000 and hitting new all-time highs. The company’s average acquisition cost across all its bitcoin holdings stands at roughly $49,874 per bitcoin, reflecting a cumulative investment of approximately $16.5 billion.

To fund this most recent bitcoin allocation, MicroStrategy sold approximately 13.6 million shares in the company. This approach aligns with its ongoing “21/21 plan,” an ambitious fundraising strategy to raise $42 billion through equity and fixed-income securities over the next three years.

Since its initial bitcoin purchase in August 2020, MicroStrategy has positioned bitcoin as a core reserve asset, accumulating it to hedge against inflation and diversify its corporate treasury. MicroStrategy has open-sourced its bitcoin reserve strategy, and it has also been adopted by other publicly traded companies such as bitcoin miner Marathon Digital Holdings (MARA) and healthcare company Semler Scientific (SMLR).
