Strategy Buys $2B in Bitcoin, Controls 4% of Total Supply in 2026

Strategy added 24,869 BTC between May 11 and May 17, spending $2.01 billion at an average of $80,985 per coin — even as Bitcoin was trading below $77,200 when the announcement landed on May 18. The purchase pushes the firm’s cumulative holdings to 843,738 BTC, representing roughly 4% of the 21 million Bitcoin that will ever be mined.

The buy was the company’s sixth-largest weekly acquisition on record and the second-largest of 2026 so far, trailing only the 34,164 BTC purchased in April. On the same morning the announcement dropped, BlackRock added $535 million in MSTR shares — a divergence from retail investors who sent the stock down 2.51% in premarket trading.

The Purchase in Numbers

Strategy’s May 11–17 acquisition breaks down as follows:

• BTC acquired: 24,869 coins
• Total cost: $2.01 billion
• Average price paid: $80,985 per BTC
• Total holdings after: 843,738 BTC
• Aggregate cost basis: $63.87 billion at $75,700/BTC blended average
• BTC Yield YTD 2026: 12.6%

At Bitcoin’s May 18 trading price of roughly $77,200, the latest batch was about 4.7% underwater on paper. The broader position — purchased at a blended average of $75,700 — remains marginally profitable. Strategy’s preferred performance metric is BTC Yield, which measures the rate at which BTC per diluted share grows as capital is deployed. At 12.6% YTD, the company is tracking ahead of its 2025 pace.

How STRC Funds the Machine

The acquisition was funded almost entirely through STRC, Strategy’s Series A Preferred Stock sold via at-the-market offerings. Between May 11 and May 17, the company placed 19.95 million STRC shares for $1.95 billion in net proceeds, then supplemented the purchase by selling 430,344 MSTR shares for an additional $83.7 million.

Unlike convertible bonds — which carry fixed maturity dates requiring repayment — preferred stock gives Strategy a perpetual capital structure with no hard refinancing cliff. Dividends are owed to STRC holders, but those can be managed through retained earnings, new issuance, or theoretically even Bitcoin proceeds.

The result is a near-continuous funding loop: investors seeking yield buy STRC, proceeds flow directly into Bitcoin, BTC Yield rises, which in turn supports MSTR equity prices, which enables more capital raises. The model works as long as:

1. Capital markets remain open to STRC issuance
2. Bitcoin prices hold above $75,700 (current blended average)
3. Preferred dividend obligations remain serviceable relative to company cash flows

Peter Schiff highlighted the risk after the May 18 announcement, arguing that Strategy’s overall gain across five-plus years of Bitcoin buying amounts to approximately 2.5%, which he calls disappointing given the leverage and preferred dividend obligations. Strategy bulls counter that 2.5% in dollar terms understates the picture, since MSTR stock has appreciated hundreds of percent since the company began its Bitcoin strategy in 2020.

BlackRock Moves the Other Direction

While MSTR fell 2.51% to $172.97 in premarket trading on May 18, BlackRock added $535 million in MSTR shares to its own holdings on the same session.

BlackRock’s iShares Bitcoin Trust (IBIT) already holds over 620,000 BTC in client assets. By simultaneously increasing its MSTR stake — a company holding 843,738 BTC — BlackRock now has indirect exposure across two vehicles to more than 1.4 million Bitcoin combined.

Throughout Q1 2026, institutional asset managers have been treating Bitcoin price dips as entry points rather than exits. That behavior contrasts with the retail-driven sell pressure that pushed MSTR lower in premarket on the same morning.

The signal from BlackRock’s move is that at least one major institution views Strategy’s latest purchase — made above spot price — as a long-term accumulation event rather than a near-term trading mistake.

What 4% of Supply Actually Means

Bitcoin’s hard cap is 21 million coins. As of May 2026, approximately 19.8 million have been mined. Estimates of permanently lost Bitcoin — wallets with missing keys, early unmoved coins widely assumed to be inaccessible — range from 3 million to 4 million BTC.

Strategy’s 843,738 BTC represents:

• 4.0% of the 21 million hard cap
• 4.3% of currently circulating supply
• 5–6% of the estimated liquid supply, once permanently lost coins are removed from the denominator

That concentration has structural consequences. Strategy’s holdings act as a permanent demand anchor: those coins are highly unlikely to reach the market under ordinary circumstances. Each weekly purchase raises that floor. The more BTC Strategy accumulates, the more the effective liquid supply shrinks — tightening the relationship between new demand and price discovery.

For comparison, in early 2025 the combined U.S. spot Bitcoin ETFs held roughly 850,000 BTC at peak. Strategy alone now matches that figure, held by a single corporate entity with no obligation to redeem shares for Bitcoin.

Bitcoin’s Price Context and the May Pullback

Bitcoin’s slide from above $81,000 (touched briefly after the CLARITY Act Senate Banking Committee vote on May 14) back to $77,200 by May 18 was driven by macro factors: renewed Middle East tensions pushed oil prices and Treasury yields higher, pressuring risk assets. The CLARITY Act passage — the committee voted 15–9 on May 14 to send the bill to the full Senate floor — was a genuine positive catalyst, but macro headwinds overpowered the regulatory tailwind within days.

For Strategy, the timing created an optics problem: announcing a $2 billion purchase at $80,985/BTC when the current price is $77,200 invites criticism. But the firm has purchased at premium prices before and held through larger drawdowns. In March 2025, Strategy was sitting on a 40% unrealized loss at Bitcoin’s trough, yet maintained its position and ultimately recovered.

The blended average of $75,700 per BTC — representing 843,738 coins acquired since August 2020 — places the company in a different position than newer entrants buying only at current prices.

The Corporate Treasury Race Widens

Strategy is no longer alone in the corporate Bitcoin treasury game. The model has spawned several competitors and variations in 2026:

• Bitmine Immersion Technologies (BMNR) has adopted a similar playbook for Ethereum, holding 5.28 million ETH as of May 17 — roughly 4.37% of ETH’s circulating supply — after adding 71,672 ETH in the same week Strategy made its Bitcoin purchase.
• American Bitcoin, backed by Trump-linked investors, has followed a BTC accumulation strategy mirroring Strategy’s capital structure.
• Multiple smaller companies have issued preferred shares or convertible notes to fund Bitcoin purchases, citing Strategy’s playbook.

These companies function as permanently long, leveraged closed-end crypto funds — with the added complexity of preferred dividends, equity issuance, and public balance sheet scrutiny that pure ETFs avoid.

For retail investors, the implication is that large price dislocations may be dampened on the downside by corporate accumulation behavior, but amplified on the upside as BTC Yield metrics drive competitive pressure to acquire more.

What This Means for Investors

Strategy’s $2.01 billion purchase, even executed above spot price, does three things that matter for Bitcoin market structure:

1. It raises the supply floor.

843,738 BTC in a corporate treasury held by a company with no near-term liquidity need is roughly equivalent to those coins being removed from tradeable supply under normal conditions.

2. It validates the conviction narrative.

Buying $2 billion in Bitcoin after a 7% price decline from a local high — and watching BlackRock add to MSTR on the same day — signals that institutional demand is not breaking at current price levels.

3. It stress-tests the STRC model.

The funding loop only works if preferred investors keep buying STRC. The latest raise of $1.95 billion in one week shows that appetite remains intact even as Bitcoin trades below the latest average purchase price.

The risks are clear. If Bitcoin falls below $75,700 — Strategy’s overall blended average — the firm’s balance sheet flips to an unrealized loss, dividend sustainability becomes a question, and STRC issuance may stall. Schiff’s criticism points at a real structural lever: Strategy’s model requires Bitcoin to not fall too far, for too long.

For portfolio positioning, Bitcoin at current levels (~$77,200) offers a roughly 2% margin above Strategy’s blended average, a level the firm has described as its minimum viability threshold. That proximity makes the $75,000–$76,000 range a logical support zone to monitor. A sustained break below it would test the corporate treasury thesis in ways not yet seen in this cycle.
