On-chain wallet analysis shows that Bitcoin whales accumulated as much in the first five months of 2026 as they did during all of 2025. Even with prices moving higher, there has been little sign of broad profit-taking from those addresses. The accumulation trend that picked up from the 2023 lows has stayed in place through rallies and pullbacks alike.
The buying is not limited to traditional large holders. Medium-sized wallets and some previously dormant addresses have also started opening new positions. That shift points away from short-term trading and toward slower, more deliberate position building. The report says flows into both spot and futures exchanges are part of what is supporting this broader wave of positioning.
Exchange BTC balances keep shrinking
The amount of Bitcoin held on exchanges has continued to fall in recent months. Investors are moving coins off-platform for long-term storage or custody services, cutting the supply that remains readily available in spot markets. With fewer coins sitting on exchanges, even relatively small orders can have a larger effect on price.
Order book depth has weakened on both sides of the market. That means the volume needed to absorb trades without sharp price movement is lower than before, so large buy or sell orders can move Bitcoin faster. The article also points to ETF inflows and ongoing institutional purchases, including government-affiliated participants and corporate treasuries, as forces tightening exchange supply even more.
From 2023 to 2026, the supply picture changed
The comparison in the report outlines a clear progression. In 2023, whale accumulation began from market lows, exchange supply declined gradually, and ETF demand remained low. In 2025, whale buying stayed high, exchange balances kept dropping, and ETF demand started to rise. By the first five months of 2026, whale accumulation had already matched 2025 levels, exchange supply had fallen to the lowest levels cited in the article, and ETF demand was high.
With whales and long-term holders showing limited interest in selling, the pool of BTC available on exchanges keeps getting smaller. That creates upward pressure on price. Thinner order books also mean any fresh wave of buying can trigger sharper market moves than traders might expect.
Lower supply and thinner depth point to bigger swings
The article argues that structural declines in both available supply and order book depth could make Bitcoin price action more pronounced than in previous years. BTC withdrawn from exchanges is increasingly being concentrated in the hands of experienced investors and institutions, a sign that the market may be entering a different phase.
If whale accumulation continues through the rest of 2026, medium-term liquidity swings may show up more often. Market observers say any new demand wave could hit a limited liquidity pool and move prices quickly, with the current Bitcoin cycle being shaped more heavily by institutions and large holders.
