“Bonds Are Toxic”: Michael Saylor Says Microsoft Could Make $4 Trillion Buying BTC

Michael Saylor has made bold claims before, but this one might be his most ambitious yet. Saylor explained to a packed audience at the Bitcoin for Corporations 2025 event why he thinks Microsoft should buy $75 billion worth of Bitcoin. You heard it right, $75 billion!

Michael Saylor Recommends Bitcoin Over Bonds As $MSTR Stock up 29% YTD

He said this move could help the company earn up to $4 trillion, calling Bitcoin the best-performing capital asset available today. For context, the entire market cap of Microsoft today is just over $3 trillion.

“You destroy 99.7% of your capital buying bonds and 97% buying back your own stock. But with Bitcoin, you’re buying a high-growth digital monopoly, at one times revenue.”

The pro-bitcoiner also called bonds “toxic”, slammed traditional treasury strategies, and said Bitcoin is the only asset outperforming everything else with consistency. 

In a direct pitch to the Microsoft board, Saylor stated that they gave up $200 billion in capital over the past five years through dividends and stock buybacks. He called this idea a not-so-brilliant way to give up key resources during a critical time.

It is worth noting that, Strategy stock (NASDAQ: MSTR ) has outperformed most S&P 500 stocks in 2025 with a 29% returns year to date amid the Trump tariffs.

The former CEO of MicroStrategy claimed that while bonds and treasuries expose companies to inflation, volatility, and counterparty risk, Bitcoin provides a censorship-resistant, decentralized store of value. “It’s the apex capital asset,” he said, adding that BTC has outperformed Microsoft, the S&P 500, and every other major asset class in the last decade.

In fact, Saylor has recently revealed the company’s plans to raise up to $84 billion by selling stocks to purchase additional Bitcoin.

For Saylor, Bitcoin Is Default Treasury Asset of the Future

His analysis showed that MicroStrategy’s stock surged from $12 to over $390 after adopting a Bitcoin standard, and that it raised over $37.5 billion in new capital since 2020. He believes any company can follow this,  

“Bitcoin is the universal merger partner, reversible, liquid, and immortal.”

Microsoft may have passed on the idea for now. But Saylor’s pitch went viral, adding fuel to the conversation around Bitcoin as a corporate treasury asset. “You want to make $4 trillion?” he concluded. “It starts with a single decision.”

This speech comes just after MicroStrategy added more BTC to its vault. This time, the company paid $180 million to purchase 1,895 BTC, increasing its total Bitcoin holdings to 555,450 BTC.
