Michael Saylor built his legend on one promise — buy Bitcoin, never sell. Now, Strategy is sending BTC to Coinbase Prime, repurchasing debt instead of buying more, and Polymarket gives 84% odds of a sale by year-end.
Key Facts of Strategy (MSTR)
Microstrategy just deposited 411.48 BTC — worth $30.3 million — into Coinbase Prime. On-chain data confirmed two transfers: 205.3 BTC and 206.2 BTC. That single move sent shockwaves through crypto markets. And it's just the beginning of the story.
For years, Saylor repeated one message. Buy Bitcoin. Hold forever. Sell nothing. That stance made him the crypto market loudest bull. It also made Strategy the world's biggest corporate Bitcoin buyer.
Then came 2026. Bitcoin Price fell from its record high near $126,000 to $73K. $MSTR stock came under pressure. And Saylor began choosing different words.
"Any model limited only to equity or only to credit or only to Bitcoin always underperforms." — Michael Saylor, May 2026
In a May 22 interview, Saylor said selling might be needed to maximize Bitcoin-per-share over seven years. His CEO, Phong Le, added that selling near the company's cost basis would avoid large tax bills. "Sell Bitcoin at cost basis, break even, no tax," Le said.
Deposits to Coinbase Prime don't always mean a sale is coming. Companies move crypto there for custody or OTC (over-the-counter) trading. But the timing matters here.
Microstrategy also spent $1.38 billion this week to buy back $1.5 billion of its own convertible notes — debt it took on to buy Bitcoin. Instead of buying more BTC, it bought back bonds at an 8% discount. That's a shift in priorities you can't ignore.

Will Strategy sell BTC before Dec 31, 2026? Polymarket bets that the chances are 84%
Here's the uncomfortable truth. Strategy didn't just buy Bitcoins. It was removed from circulation. Consistently. At scale. That matters in a market where supply is capped at 21 million coins.
Strategy buying reduced the available supply on exchanges
Less supply and steady demand pushed prices higher
Selling would reverse that — adding supply back to the market
More supply without matching demand puts downward pressure on prices
Saylor himself admitted this. He said Bitcoin might trade near $40,000–$50,000 today without Strategy's five years of buying. That's a 45% discount to current prices.

Gold advocate Peter Schiff didn't hold back. "You're running out of cash. What will you sell next to keep the wheels from falling off?" he posted on X.
Strategy pushed back. It says the bond buyback generated $333 million in gains and added 24,869 coins via fresh stock and preferred share issuance. Year-to-date BTC yield: 13.3%.
But the optics are hard to spin. The biggest Bitcoin buyer in corporate history is now buying bonds and hinting at sales.
What this means for you: If you hold MSTR stock, the rules that drove prices for five years may be changing. Don't panic — but don't assume the old playbook still applies.

Here's the other side of the story. Bitcoin spot ETFs keep pulling in institutional money. Long-term adoption hasn't reversed. Microstrategy is one buyer — a big one, but not the only one. If ETF demand fills the gap Strategy leaves, prices could hold. If it doesn't, you'll see the stress test Saylor always said would never come.
Saylor also wants STRC's preferred stockholders to vote on paying dividends twice a month instead of once. The annual yield stays at 11.5%. Just split across more paydays. The vote deadline is June 7, with the first new payment date on June 30. About 80% of STRC holders are regular retail investors, so this directly affects individual income planners.

Saylor shifting from buyer to possible seller doesn't end the story — but it rewrites a key chapter. Watch on-chain flows, watch Polymarket odds, and watch what MSTR does next.
