Strategy’s $8.5 Billion Preferred Stock Engine Fuels a Bitcoin Buying Spree — and a Concentration Risk Debate

Strategy’s $8.5B preferred stock STRC funds massive Bitcoin accumulation, but concentration risk looms as MSTR market cap hovers near net asset value.

Michael Saylor took the stage at the Bitcoin Conference 2026 on Tuesday with a characteristically bold prediction: a supply shock is looming that could reshape the entire crypto landscape. The Strategy executive chairman argued that between $20 billion and $100 billion in fresh credit capital could flood the market over the next twelve months, while only about $10 billion worth of Bitcoin is currently available for sale. That mismatch, he insists, is the real driver of valuation.

But beneath the headline-grabbing forecast lies a more concrete story about how Strategy itself is financing its relentless accumulation. The company’s preferred stock vehicle, trading under the ticker STRC, has swelled to a notional value of roughly $8.5 billion in just nine months, growing at an annualized rate of approximately 350 percent. Designed to filter Bitcoin volatility out of cash flows, the instrument has so far attracted about 80 percent of its capital from retail investors. In April alone, the inflow was so strong that on an annualized basis it would represent $38 billion. Over the first four months of 2026, STRC funded the purchase of roughly 77,000 BTC.

The scale of Strategy’s buying power is unmatched. The company now holds 818,334 Bitcoin — nearly 4 percent of the total circulating supply — acquired at an average price of $75,537 per coin, for a total cost basis of $61.81 billion. That makes it the dominant corporate holder by a wide margin: Twenty One Capital, the next-largest competitor, owns just 43,514 BTC. Strategy accounts for more than 76 percent of all Bitcoin held on corporate balance sheets globally. In the past 30 days, while other corporate buyers combined purchased roughly 1,000 coins, Strategy was the only meaningful buyer in the market.

That concentration is drawing increasing scrutiny as the company prepares to report first-quarter results on May 5. The most recent purchase, between April 20 and 26, added 3,273 Bitcoin at an average price of $77,906. Analysts expect revenue of around $120.75 million, but the spotlight will be on the mark-to-market valuation of the Bitcoin hoard — now more than 815,000 BTC — and the growing debate over what happens if Strategy is ever forced to sell.

The risk is structural. Strategy’s coins sit on a single corporate balance sheet, financed through a complex web of common and preferred equity offerings. According to the company’s own investor presentation, it would sell Bitcoin if the ratio of market capitalization to net asset value falls below 1.0 — meaning if the MSTR stock price drops below the value of the coins it holds. That ratio only recently recovered to 1.0 after weeks languishing below it. The contrast with ETF structures is stark: the iShares Bitcoin Trust ETF holds roughly 802,000 Bitcoin, but those belong to thousands of independent investors, and redemptions flow through ETF shares without forcing the underlying coins onto the market. A forced sale by Strategy would be a concentrated blow to Bitcoin’s price.

For now, though, Saylor’s machine keeps running. In the week from April 20 to 26 alone, Strategy sold 1.45 million common shares for net proceeds of $255 million. The remaining issuance capacity stands at $26.47 billion, supplemented by multiple preferred stock offerings. Management tracks success through a metric called BTC Yield, which measures the growth in Bitcoin holdings per share despite dilution. That figure stands at 9.6 percent year-to-date in 2026.

The stock itself tells a more cautious story. MSTR closed Tuesday at $163.31, down slightly amid geopolitical uncertainty and weak earnings from other crypto-adjacent companies. Robinhood’s crypto trading fees fell 47 percent year-over-year in the first quarter, suggesting investors are rotating away from active trading toward structured products and direct treasury positions. MSTR currently trades at €139.32, roughly 27 percent below its 200-day moving average and well off its April highs.

Analysts remain broadly bullish: all 14 covering the stock rate it a buy, with a 12-month average price target of $372.50. But operating losses and negative free cash flow weigh on the fundamental picture — a contradiction that the May 5 earnings call will likely put front and center. For the first time, management will have to publicly address the twin narratives of concentration risk and capital structure sustainability, even as Saylor continues to bet that the supply shock he predicts will make those concerns moot.
