Strategy Inc. (MSTR) fell more than 9% at times on Thursday to its lowest level since March 2024, extending a five-day collapse of nearly 30% as Bitcoin broke below $60,000 and a securities investigation targeting the company became public.

Shares of the Michael Saylor-led Bitcoin treasury company hit $85 by midday Thursday, down from above $117 at the start of the week. The stock has now shed roughly 36% over the past month — nearly double the 18.5% decline in Bitcoin over the same period.

On top of this, Rosen Law Firm posted a press release saying it is investigating potential securities fraud claims against Strategy, alleging the company “may have issued materially misleading business information to the investing public.” The probe covers all five of Strategy’s publicly traded securities: MSTR, STRF, STRC, STRK, and STRD. 

The legal pressure compounds a financial squeeze that analysts say stems from Strategy’s own capital structure. 

The company holds 847,363 Bitcoin — the largest corporate stockpile in the world — purchased at an average price that now leaves the entire 2024, 2025, and 2026 acquisition tranche underwater. Unrealized losses on the Bitcoin portfolio stand at approximately $10.6 billion.

Strategy’s preferred stock breaks down

The deeper concern for investors is Strategy’s STRC preferred stock, which has crashed to an all-time low and now trades around $76 — roughly 24% below its $100 par value. The structure matters because Strategy has relied on selling preferred stock to fund ongoing Bitcoin purchases. 

When preferred shares trade below par, that capital-raise mechanism stalls.

As Strategy issued more STRC over the past six months, annual dividend obligations ballooned from $300 million at the start of 2026 to $1.2 billion — a fourfold increase. Cash reserves, meanwhile, fell 38% over the same period. 

CryptoQuant, the on-chain analytics firm, published a note June 23 urging Strategy to stop buying Bitcoin and rebuild its cash position to roughly $2.8 billion before resuming accumulation. The firm said dividend coverage has collapsed from more than seven years to approximately 14 months.

Strategy appears to have gotten the message before the report landed. In the week of June 22, the company bought just 520 Bitcoin for roughly $35 million — a fraction of its prior pace — and routed $300 million of a $335.5 million common stock raise into its cash reserve, lifting it to $1.4 billion.

Saylor has not commented publicly on the investigation or CryptoQuant’s warning.
