- • Bitcoin surged more than 5% on April 13, approaching $75,000 per coin, driven partly by a short squeeze on leveraged positions above $72,000 and whale accumulation providing underlying demand.
- • Major whale entities moved $4.7 billion into cold storage, indicating long-term holding intentions and conviction in higher valuations ahead.

Summary
Bitcoin whales have executed a significant accumulation campaign in April 2026, with on-chain data revealing the largest monthly net buy by these major investors in over 13 years. According to analytics firm Santiment, whale-sized wallets (investors holding between 1,000 and 10,000 BTC tokens) have collectively purchased 27,652 BTC worth more than $2 billion in a single day during the weekend preceding April 17. This aggressive buying has pushed combined whale supply to 4.25 million BTC, representing the highest level since mid-February 2026.
The accumulation activity coincides with Bitcoin's sharp upward price movement. On April 13, Bitcoin surged more than 5% and climbed toward $75,000 in its strongest move in weeks. Market analysis suggests this rally was turbocharged by forced buying from short-sellers caught in a squeeze above the $72,000 price level, combined with substantial whale accumulation that provided underlying bid support. The synchronized large investor buying and technical squeeze created compounding upward pressure on the asset.
Whale behavior has undergone a notable reversal in recent weeks. After a distribution phase that bottomed out in mid-March, these major investors have shifted decisively into accumulation mode. The recent buying surge accelerated during the weekend, with whales demonstrating sustained conviction. Additionally, whale entities moved $4.7 billion into cold storage during this period, signaling long-term holding intentions rather than near-term profit-taking. Cold storage transfers typically indicate that major investors are securing assets for extended holding periods, reinforcing the narrative of accumulated positions being held for price appreciation.
Given the demonstrated scale and decisiveness of whale activity, market participants are monitoring this cohort closely. Whale-sized investors hold sufficient capital concentration to meaningfully influence price discovery, and their recent shift from distribution to aggressive accumulation suggests conviction about Bitcoin's direction. However, as with all market participants, whale behavior can reverse quickly, making continued on-chain monitoring essential for institutional investors evaluating near-term and intermediate-term Bitcoin exposure.
