Key Highlights

  • Bitcoin held by long-term, low-activity addresses has climbed to a record 4 million BTC, a roughly 300% increase since late 2025, draining liquid supply from exchanges and compressing the pool of coins available for daily trading.

  • Bitcoin reserves on exchanges have fallen to approximately 2.69 million BTC, down 170,000 BTC over six months, as institutional buyers and corporate treasuries continue absorbing newly mined supply faster than it enters circulation.

  • Public companies now collectively hold a record 1.19 million BTC across more than 180 corporate treasuries, representing roughly 5.7% of bitcoin's total supply and adding structural demand that did not exist in prior market cycles.

Bitcoin's long-term holder base has expanded to a record 4 million BTC, according to on-chain data published by CoinDesk on May 13, reflecting a roughly 300% surge in high-conviction accumulation since the end of 2025. The buildup represents the largest two-quarter increase in supply moving into low-activity addresses since the 2020 crash, when institutional buyers first began treating bitcoin as a treasury reserve asset.

The accumulation has come at the direct expense of exchange liquidity. Bitcoin reserves on tracked exchanges have fallen to approximately 2.69 million BTC, a 170,000 BTC reduction over six months, as buyers move coins into cold storage rather than leaving them on trading platforms. Declining exchange balances reduce the pool of bitcoin available for spot selling, which analysts said historically acts as a structural tailwind when fresh demand enters the market.

Corporate treasuries have been a significant driver of the trend. Public companies across more than 180 balance sheets now collectively hold a record 1.19 million BTC, representing roughly 5.7% of bitcoin's 21 million coin supply. Strategy remains the largest corporate holder, and several companies that began purchasing bitcoin in 2025 have continued adding to positions despite the price volatility that marked the first quarter of 2026.

Long-term holder accumulation at this scale does not guarantee near-term price movement, but analysts noted the compression of liquid supply creates conditions where relatively modest demand increases can produce outsized price responses. With spot ETFs recording six consecutive weeks of net inflows and exchange balances declining simultaneously, the setup is one analysts have historically associated with a supply shock when demand accelerates.
