Saylor's Strategy Bought ~15,000 BTC This Week — Monday 8-K Filing to Confirm

Michael Saylor posted his trademark Sunday tease — "Big Dot Energy" — hinting at another large Bitcoin purchase. Independent tracker Strc.live estimates roughly 15,466 BTC (around $1.59 billion) flowed into Strategy's holdings across four trading days last week.

Strategy (formerly MicroStrategy) chair Michael Saylor has made Sunday social posts teasing upcoming Bitcoin buys a near-weekly ritual. May 17 was no different. Monday's anticipated 8-K filing is expected to officially confirm the scale of last week's accumulation.

This week's buy — one of the largest of 2026

Independent tracking site Strc.live estimates 15,466 BTC were accumulated across four active trading days. At approximately $103,000 per Bitcoin, that's roughly $1.59 billion in purchases — one of Strategy's biggest weekly runs of the year.

• Estimated weekly buy: 15,466 BTC ≈ $1.59 billion
• Total holdings: 818,869 BTC at an average cost of ~$75,543/coin
• Total acquisition cost: approximately $61.8 billion
• STRC preferred share volume: 15.1 million shares on Thursday — all-time record

Thursday's record STRC volume was the tell. Strategy funds its Bitcoin purchases by issuing STRC preferred shares in at-the-market offerings. When volume spikes, the market reads it as fresh capital being deployed into Bitcoin.

Convertible note buyback and the capital flywheel

Strategy recently completed a $1.5 billion repurchase of its 2029 convertible notes, settling around May 19. Even with that capital outlay, the Bitcoin buying cadence didn't slow — the STRC at-the-market issuance engine kept generating fresh proceeds.

Saylor has repeated nearly the same message every Sunday for weeks. There's no surprise for the market — they already know his routine.

STRC dividend frequency vote

Strategy is asking STRC holders to approve switching dividend payments from monthly to semi-monthly. The annual rate stays at 11.5% — only the payment interval shortens.

Roughly 80% of STRC is held by retail investors at Charles Schwab, Fidelity, and Robinhood. More frequent cash flows are generally more attractive to income-seeking retail holders. If approved, the change could sustain demand for STRC shares, keeping the at-the-market issuance pipeline — Strategy's primary Bitcoin funding source — intact.
