Raphael Zagury, newly appointed CEO of Twenty One Capital — the second-largest corporate Bitcoin holder in the world at 43,514 BTC — is confirmed to keynote the Bitcoin Treasuries Conference 2026.
Zagury took the helm three weeks ago, succeeding Jack Mallers. Make no mistake, this is a new chapter for XXI. “Our business will perform best when we focus on the cash flow we generate and the rigor with which we allocate capital, not only by the Bitcoin we hold,” he said on taking the role.
Before XXI, he built Elektron Energy into one of the most efficient Bitcoin mining and infrastructure operations anywhere. Before that, he cut his teeth on Wall Street: Goldman Sachs, Deutsche Bank, and Merrill Lynch.
Now, his mandate is explicit: build XXI into a powerhouse Bitcoin operating company, not only a treasury. Zagury’s strategic vision is inspired by Berkshire Hathaway. The company plans to expand its capital markets activity, acquire businesses measured against Bitcoin as the benchmark, and build out a Bitcoin-native lending platform.
So far, the company with the second-largest Bitcoin balance sheet has revealed little in public. On September 28, that changes.
Zagury joins Adam Back, Grant Cardone, and Eric Weiss. Seats are capped at 300, and early adopter pricing is disappearing fast.
The message is clear: the world’s largest Bitcoin and digital asset balance sheet managers are converging on Manhattan. Be there.
