New data shows that major investors, known as whales, have stepped up their Bitcoin buying activity at a remarkable pace during the first five months of 2026. On-chain metrics indicate that these large holders have already acquired nearly as much BTC as they did throughout the whole of last year. The accumulation trend is seen across wallets of different sizes, with long-term holders in particular showing little inclination to sell while steadily increasing their balances.
Shift in whale accumulation behavior
Analysis of on-chain wallets in 2026 reveals that whale groups continued to amass Bitcoin even as prices reached higher levels. Despite rapid price increases, there has been little evidence of significant profit-taking among these addresses. Whale activity, which picked up from the lows seen in 2023, has persisted at a steady pace during both upward surges and corrective phases.
This pattern involves not only traditional large investors but also medium-sized and previously dormant wallets, which are now opening new accumulation positions. The focus is shifting from short-term trading to carefully planned, gradual position building. Market experts are highlighting that this broad positioning is driven by a mix of fund flows into both spot and futures exchanges.
Analysts note that whales accumulated as much in just the first five months of 2026 as they did over all of 2025. The consistency of whale activity, even during volatile periods, suggests that key price support levels may prove resilient.
Broader macro trends such as expanding liquidity, increased demand for off-exchange custody, and a surge in ETF investments are cited as key forces behind the latest wave of whale buying.

Exchange supply drops, liquidity risks rise
The amount of Bitcoin held on exchanges has continued to decline in recent months. Investors are withdrawing their coins for long-term storage or using custody services, reducing the freely available supply in spot markets. This decline means that market prices are now more sensitive to even small buy or sell orders.
Liquidity depth—how much volume can be traded without moving the price sharply—has weakened on both buy and sell sides. As order book depth shrinks, large trades can now swing the price upward or downward more quickly than before.
ETF inflows and continued institutional buying, especially from government-affiliated players and corporate treasuries, are further constricting the supply on exchanges. As a result, thinning liquidity means future demand spikes could drive prices higher with less resistance.
| Year | Whale Accumulation | Exchange Supply | ETF Demand |
|---|---|---|---|
| 2023 | Started from bottom | Gradual decrease | Low |
| 2025 | High | Continued drop | Started rising |
| 2026 (first 5 months) | Matched 2025 level | Lowest levels | High |
With whales and long-term holders reluctant to sell, Bitcoin held on exchanges is shrinking further and putting upward pressure on price. Shallower exchange order books suggest that any fresh buying waves could trigger even sharper moves than anticipated.
Market volatility and cyclical risks ahead
With both available supply and order book depth structurally shrinking, Bitcoin’s price movements are expected to be more pronounced compared to previous years. Experts argue that Bitcoin withdrawn from exchanges is being concentrated in the hands of experienced or institutional investors, signaling the possible beginning of a new market phase.
If this whale accumulation phase persists through the rest of 2026, mid-term liquidity swings may become more common. Consistent buying pressure could intensify not only during downtrends but also in rising markets.
Major buyers in the Bitcoin market have chosen to hold onto their assets instead of selling, even as prices climb. Depleting BTC reserves on exchanges could make new waves of purchases more volatile.
Market observers believe that any new waves of demand could impact the limited liquidity pool and trigger fast price moves. Overall, these developments suggest that Bitcoin’s current cycle is increasingly shaped by institutional investors and large holders.
