Whale Activity Surges as Bitcoin Builds Momentum Toward New Highs

Bitcoin BTC is witnessing a notable resurgence in accumulation activity across all investor cohorts, with whale wallets leading the charge.

According to recent data from Glassnode, the number of unique whale entities, defined as those holding at least 1,000 BTC, has risen from 1,392 to 1,417 over the past week. This marks one of the highest whale counts recorded in 2025, signaling a resurgence in institutional or large-scale investor confidence.

Glassnode identifies entities as clusters of addresses controlled by the same user or organization.

In addition, the Accumulation Trend Score, a key on-chain metric, reveals that not only are whales accumulating aggressively, but so are the smallest holders, known as shrimps, who own less than 1 BTC. This buying pressure highlights a rare moment of alignment between retail and institutional investors.

The metric breaks down accumulation strength by wallet size and recent acquisition behavior over a 15-day period. A score closer to 1 suggests strong accumulation, while a value near 0 indicates distribution. Entities such as exchanges and miners are excluded to focus on genuine investor sentiment.

Importantly, this level of sustained accumulation across all cohorts has not been seen since November 2024, during President Trump’s re-election. That period marked a sharp uptick in bullish sentiment and price momentum that saw bitcoin claim $100,000.

Given the broad-based accumulation and the psychological boost of renewed whale interest, market observers could be increasingly confident that bitcoin is poised to challenge and potentially surpass its all-time high in the near future.
