Strategy Inc, the biggest corporate Bitcoin holder, confirmed its first Bitcoin sale in the Form 8-K on June 1, 2026.

The company sold 32 BTC for approximately 2.5 million dollars between May 26 and May 31, while holding a massive treasury of 843,706 BTC.

On-chain suspicion receives official confirmation

Traders and on-chain analysts noticed that MicroStrategy wallets were moving BTC to Coinbase Prime days prior, sparking a lot of speculation.

Arkham Intelligence and community trackers highlighted this unusual activity, leading to a bet on Polymarket about whether there would be a sale before May 31.

A trader went big on the YES bet when the market estimated the probability at around 11%. The June 1 presentation resolved the market in their favor, netting them an estimated profit of $200,000.

Details from the latest report, showing Bitcoin sales from last week, include:

• Sold: 32 BTC at an average of about $77,135 each (net of fees).

• Holdings as of May 31: 843,706 BTC with a total cost of approximately $63.87 billion (average of about $75,699 per BTC).

• Purpose: The raised funds support the dividends of preferred shares (STRF, STRC, etc.).

• Dollar reserve: $900 million set aside for obligations.

Bitcoin traded around $72,000–$74,000 during that period, so MicroStrategy sold above recent levels.

The sale represents a very small fraction (<0.004%) of the holdings but marks a shift from pure accumulation.

MicroStrategy has aggressively ramped up its treasury using capital raises and preferred shares, often buying thousands of BTC each week.

This disciplined approach, selectively shorting while replenishing funds in the capital markets, aligns with executive statements on proactive treasury management.

Preferred dividends and debt repayment remain key priorities, backed by the dedicated dollar reserve.

With Bitcoin's volatility persisting and corporate treasuries under scrutiny, larger sell-offs or accelerated buys could influence sentiment.

The Bitcoin per share indicator and MicroStrategy's performance targets will likely remain key in their strategy as they balance growth, obligations, and long-term conviction in Bitcoin.
