Joseph Chalom, who spent nearly two decades at BlackRock shaping the asset manager's blockchain and digital asset strategy, now leads SharpLink Gaming (Nasdaq: SBET) as CEO, President, and board member. He joined as Co-CEO in July 2025 and became sole CEO that December, driving the company's transformation into a publicly traded Ethereum treasury enterprise.
From BlackRock to Blockchain: Two Decades of Foundation
At BlackRock, Chalom spearheaded product innovation, strategic partnerships, tokenization initiatives, and institutional adoption of digital assets. He helped integrate blockchain technology into one of the world's largest asset managers, building a bridge between traditional capital markets and emerging crypto infrastructure.
Public details about his early life and education remain scarce, but his professional track record has earned wide recognition. His experience placed him among the executives responsible for BlackRock's expanding presence in the digital asset ecosystem.
SharpLink’s Ethereum-First Treasury Strategy
Under Chalom, SharpLink has pivoted from its sports betting technology roots to become one of the largest publicly traded corporate holders of Ethereum. The company continues to accumulate ETH while expanding its staking operations, enabling its treasury holdings to generate on-chain rewards. SharpLink describes Ethereum as a strategic reserve asset supporting its long-term corporate vision.
The firm has completed multiple large ETH acquisitions and emphasized active participation in Ethereum's network security through staking. Chalom’s institutional finance background has helped position SharpLink as a bridge between traditional capital markets and decentralized finance.
Influence Without Public Wealth Figures
Chalom's net worth has not been publicly disclosed; no verified estimates exist. Nevertheless, his influence in the digital asset sector continues to grow. His move from BlackRock to SharpLink marked one of the industry's most notable executive transitions, highlighting the accelerating convergence of traditional finance and blockchain-based financial infrastructure.
