The global credit market is worth $300 trillion and Michael Saylor believes digital credit will capture a massive share of it. In this keynote from Strategy World 2026, Saylor walks through the complete theory of digital credit from first principles: what Bitcoin is, why variable preferred equity is the longest-duration capital structure short of equity, and how STRC delivers double-digit yields with deferred tax treatment and principal protection. He also lays out the programmable future of digital money and digital yield, with ETFs, on-chain tokens, and bank accounts all being built on top of STRC as a foundation.
