What’s Happening

MicroStrategy—now rebranded Strategy—just scooped up 10,624 BTC for $962.7 million at an average price of $90,615 per bitcoin. That’s their biggest weekly buy since July. As of December 7, 2025, Michael Saylor’s crew now holds 660,624 BTC, accounting for over 3% of Bitcoin’s total 21 million supply. Total cost basis? Around $49.35 billion at $74,696 per BTC.

Saylor announced it himself on X late Saturday, calling out a YTD BTC Yield of 24.7% for 2025. This comes right after BTC dipped below $90K but rebounded hard—trading around $93,500 as of Monday morning. MSTR stock? Up 2% in after-hours on the news.

Look, we’ve seen Saylor stack sats since 2020. Back then, it was a bold pivot from enterprise software to Bitcoin treasury play. Fast forward five years, and they’re the undisputed BTC whale king.

The Numbers

Breaking it down:

Source: Saylor’s X post and CoinDesk.

Funding? Mostly fresh common stock sales, per reports. They’ve been leveraging at-the-market offerings and convertible notes nonstop. Since the 2024 halving, MSTR’s BTC stack has ballooned from under 250K to this monster level—pure leverage on BTC’s upside.

Compare to peers: BlackRock’s IBIT ETF holds about 350K BTC. Marathon Digital? Around 20K. Saylor laps the field.

Why This Matters

Saylor’s not just buying BTC—he’s engineering a yield machine. That 24.7% BTC Yield metric? It’s their way of saying, ‘We’re growing the stack faster than BTC itself appreciates.’ Bulls love it: MSTR trades at a premium to its BTC NAV (net asset value), around 2.5x lately, turning it into leveraged BTC exposure without futures or options.

But here’s the deal: This amps up BTC’s scarcity narrative. With 660K off the market, exchange balances keep shrinking. On-chain data from Glassnode shows BTC reserves on major exchanges at multi-year lows—down 15% since Q3 2025. Saylor’s hoard sucks up supply just as ETF inflows pick up post-Trump election.

Market reaction? BTC bounced from $88K support over the weekend. MSTR popped, but it’s volatile—stock’s down 10% from November highs amid broader risk-off. CT’s buzzing: ‘Saylor’s back at it, probably nothing.’

And the rebrand to Strategy? Signals a pivot. Less software, more BTC treasury ops. They’ve got $STRK, $STRF preferred shares trading, diluting common but funding the buys.

What to Watch

Short-term: BTC’s $90K level. Hold it, and $100K by Christmas isn’t crazy—Saylor himself predicts $10M long-term. Break below, and MSTR could test $200 support.

Upcoming catalysts:

• Dec 16: Strategy’s BI consolidation webinar—niche, but shows software side alive.
• Q4 Earnings: Late Feb 2026. Expect more BTC yield flexing.
• Fed Minutes: This week. Rate cuts fuel risk assets.
• On-chain: Watch MSTR’s wallet 3M217Z… for transfers. Any OTC deals?

Bear scenario: Prolonged BTC bear market. Bears whisper Saylor might sell if debt piles up—$4B+ in convertibles due 2028-2030. Bulls counter: They’d rather dilute equity forever.

Trader alpha: MSTR calls are printing if BTC grinds higher. But options implied vol is 80%—pricey.

Bottom Line

Saylor’s doubling down proves conviction, not FOMO. At 660K BTC, they’re a force multiplier for price discovery. Bullish for BTC holders, but MSTR’s premium could compress if BTC stalls. We’ve tracked this playbook since 2020—it works until it doesn’t. Eyes on $100K.
