Institutional and Whale Accumulation Shrinks Bitcoin's Liquid Supply, Boosting Price Pressures

Bitcoin's circulating supply has reached a significant milestone, with 72% of mined coins now classified as illiquid, reflecting sustained accumulation by long-term investors and institutional players. According to data from Glassnode, the illiquid supply has surged to 14.37 million BTC, up from 13.9 million at the start of 2025, with only 5.4 million BTC remaining in liquid circulation. This trend indicates a structural shift in market dynamics, as investors increasingly view Bitcoin as a long-term store of valueBTC's Illiquid Supply Climbs to 72% of Total Circulating Supply...^[1].

Illiquid supply represents coins held by entities with minimal transaction history, effectively removing them from active trading. The rise in illiquidity is driven by whale activity, with large holders (100–1,000+ BTC) absorbing nearly 300% of the annual mined supply. Corporate and institutional entities have also expanded their holdings, with strategic reserves and ETFs controlling 2.88 million BTC by mid-2025—a 30% increase from the beginning of the yearBitcoin: 72% of supply now illiquid - cointribune.com^[2].

The tightening liquidity environment has amplified supply-side pressures, reducing exchange outflows to historic lows. Exchange balances have declined as investors prioritize self-custody, with yearly absorption rates plunging below -150%. This scarcity dynamic is expected to exert upward pressure on prices, particularly as institutional demand intensifies and miner issuance diminishes.

Corporate adoption has further accelerated Bitcoin's institutionalization. Public companies now hold over 857,000 BTC collectively, with MicroStrategy controlling 70% of these holdings. ETFs, while still significant, have been outpaced by corporate accumulation, with public firms purchasing 237,664 BTC year-to-date compared to ETFs' 117,295 BTC. This shift underscores a preference for direct ownership over exchange-traded products, driven by regulatory clarity and strategic diversificationCorporate Bitcoin Holdings Surpass ETFs in Q2 2025^[5].

Upcoming halving events, scheduled to reduce miner rewards by 50%, are expected to compound supply constraints. With institutional and corporate demand already outpacing new issuance, the post-halving environment could see further price appreciation. However, risks persist, including potential corrections if large holders decide to liquidate positions.

The interplay between institutional accumulation, ETF growth, and corporate holdings is reshaping Bitcoin's market structure. As liquidity continues to tighten, the asset's role as a hedge against traditional market volatility is gaining traction. However, the concentration of supply in institutional hands also raises questions about market accessibility and price stability. Monitoring whale activity, ETF flows, and regulatory trends will remain critical for understanding Bitcoin's trajectory in the coming quartersBitcoin ETFs and Institutional Allocation – A 2025 Update^[7].
