Block holds 28,355 BTC, $2.2B; 19,357 BTC for customers

Block Inc. reported holding 28,355 bitcoin, worth about $2.2 billion, as of March 31, 2026. Of that total, 19,357 BTC (about $1.5 billion) were held on behalf of customers and 8,997 BTC (about $692.3 million) were held as corporate reserves.

The company published a first-quarter proof-of-reserves report on Monday covering bitcoin held across its corporate treasury, Square and Cash App. Independent auditors confirmed the report.

Block used on-chain cryptographic signatures to enable independent verification of the holdings. Those signatures allow outside parties to confirm that the company controls the addresses where the bitcoin are stored, without relying solely on internal records.

The report added: “People shouldn't have to trust that their bitcoin is there, they should be able to verify it.”

Proof-of-reserves measures have been adopted by many crypto firms since the collapse of FTX to provide on-chain transparency. Some observers have warned that publishing on-chain proofs can expose firms to security risks; Michael Saylor argued in May 2025 that on-chain proof-of-reserves could create vulnerabilities.

Block's report provides a split between customer and corporate holdings rather than a single aggregate figure and gives an auditable snapshot as of the end of the first quarter. The company is scheduled to report first-quarter earnings on May 7, 2026.

In its fourth-quarter 2025 filing, Block reported net income of $115.7 million, compared with $1.9 billion in the same period a year earlier. The company's shares closed 0.49% lower at $71.28 on Monday and had risen about 24.9% over the prior month.
