Summary
Block Inc., the fintech platform controlled by Twitter co-founder Jack Dorsey, has substantially increased its bitcoin holdings as part of a multi-year corporate treasury strategy that began in 2020. According to the company's Q2 2026 10-Q filing, Block currently holds 8,692 BTC worth over $1.15 billion at current market valuation, representing a 108 BTC net addition during the second quarter. This ongoing accumulation reflects Block's strategic commitment to building a significant cryptocurrency reserve as a core component of its long-term business positioning.
In July 2025, Block achieved a major institutional milestone by joining the S&P 500 index, marking the second pure-play digital asset company to receive this classification following Coinbase. The index inclusion generated a 10% aftermarket stock price increase and signals meaningful acceptance of cryptocurrency-focused business models within traditional institutional investment frameworks. Block's entry displaced Hess Corporation, which exited the index following its acquisition by Chevron.
Block's bitcoin strategy operates through a disciplined profit-recycling mechanism established in mid-2025. The company commits to converting 10% of its gross bitcoin profits into additional BTC purchases on a monthly basis, creating a compounding effect that accelerates treasury growth while maintaining operational flexibility. This approach differs from traditional buy-and-hold strategies by linking treasury expansion directly to cryptocurrency asset performance. Block publicly open-sourced this treasury blueprint in 2025, encouraging other corporations to adopt similar frameworks.
The company's digital asset ecosystem extends beyond treasury management through specialized business units. Bitkey operates as a self-custody bitcoin wallet designed for mainstream accessibility, while Proto delivers a comprehensive suite of bitcoin mining products and services. These initiatives, alongside Cash App's cryptocurrency payment functionality, position Block as a vertically-integrated player across custody, mining, and transaction layers of the bitcoin infrastructure. Management has explicitly articulated that Block's future strategy prioritizes bitcoin expansion across all operating divisions, representing a fundamental pivot from its original 2009 founding as a mobile payments processor under the Square brand name.
