Block Inc. Publishes Proof-of-Reserves Report Revealing $2.2 Billion in Bitcoin Holdings

Block Inc., a leading provider of financial services, has made significant strides in its commitment to transparency and security in the cryptocurrency space. In a recent move, the company published its first-ever proof-of-reserves report, revealing a substantial holding of Bitcoin (BTC) worth $2.2 billion.

The report disclosed that Block's total holdings amount to 28,355 BTC as of March 2026, with 19,357 BTC held on behalf of customers and 8,997 BTC in corporate reserves. The company emphasized the importance of transparency in cryptocurrency reserves, stating that 'people shouldn't have to trust that their bitcoin is there; they should be able to verify it.' To facilitate this verification, Block has employed on-chain signatures, allowing users to independently confirm its reserves are actively controlled and not just historically observed.

The publication of the proof-of-reserves report comes as institutional investors continue to accumulate Bitcoin. This trend is evident in the recent net inflows of $1.1 billion into U.S. spot Bitcoin ETFs across five consecutive trading sessions, followed by an outflow yesterday. The accumulation of BTC by these investors could potentially tighten supply and drive up prices.
