Block Inc. published its first-ever Bitcoin proof-of-reserves report on April 27, disclosing 28,355 BTC held as of March 2026 — split between 19,357 BTC custodied on behalf of customers and 8,997 BTC in corporate reserves. At the current $BTC price near $76,500, the combined stack is worth roughly $2.2 billion. The disclosure uses on-chain signatures so anyone can independently verify the reserves are actively controlled, with Block stating that "people shouldn't have to trust that their bitcoin is there, they should be able to verify it."
Why it matters
The report lands in the same 24-hour window as Michael Saylor's Strategy disclosing a fresh 3,273 BTC purchase for ~$255 million at ~$77,906 per coin. Strategy now holds 818,334 $BTC acquired for ~$61.81 billion at an average ~$75,537, with year-to-date BTC Yield of 9.6%. For Block, the conviction dates back to its original 4,709 BTC purchase in October 2020 — the disclosure isn't a new thesis but the compounding of one. Block's decision to anchor customer custody to verifiable on-chain proof is a notable step for a public company sitting on a nine-figure BTC treasury.
Market impact
The institutional bid has tightened visibly. U.S. spot $BTC ETFs recorded $1.1 billion in net inflows across five consecutive trading sessions before a single outflow day on April 26, the kind of streak that absorbs sell pressure into structural demand. Spot is currently recovering from a $63,000 low earlier in 2026 to trade near $76,500, with $75,000 acting as the nearest meaningful support and $79,000 a resistance cluster tested multiple times this week. A clean break above $79K on volume could open a path toward $80,000. The signal across Block's proof-of-reserves, Strategy's continued accumulation, and the ETF inflow streak points to a bid that is institutional and corporate in nature rather than reactive to short-term price action.
