## Briefing

Mid-sized Bitcoin investors, often called “sharks” (wallets holding 100-1,000 BTC), are showing unprecedented accumulation, reaching an all-time high of over 3.65 million BTC in their portfolios. This aggressive buying, which saw nearly 65,000 BTC added in the last seven days alone, has created a supply deficit, historically preceding significant bullish market phases. The core insight is that conviction among these well-capitalized investors is robust, with their [sustained accumulation](https://incrypthos.com/insights/bitcoin-selling-pressure-persists-accumulation-remains-weak-uncertainty-reigns/) serving as a powerful indicator of potential upward price movement.

## Context

Many in the market wonder if Bitcoin’s recent price movements are sustainable or if larger players are preparing to sell. This data helps answer whether significant capital is flowing into Bitcoin, particularly from strategic, mid-tier [investors](https://incrypthos.com/news/investors/), or if the market lacks conviction for a sustained rally.

## Analysis

The key metric here is “Shark Net Position Change,” which measures the aggregate change in Bitcoin holdings by entities with 100 to 1,000 BTC. When this indicator shows a positive figure, it means these mid-sized whales are adding to their holdings, indicating strong conviction and a belief in [future price appreciation](https://incrypthos.com/insights/whale-accumulation-drives-bitcoins-price-surge-and-future-potential/). A negative figure would suggest selling pressure. Currently, the data reveals a significantly positive trend, with sharks accumulating at the fastest rate this year.

This pattern of consistent accumulation, rather than selling into price rallies, has historically been a precursor to major [bullish market phases](https://incrypthos.com/insights/bitcoin-shark-accumulation-signals-strong-bullish-market-momentum/). Their total holdings have now surpassed 3.65 million BTC, an all-time record, demonstrating a growing concentration of supply in the hands of these powerful investors. This aggressive buying has absorbed both secondary market supply and new issuance, leading to a net supply deficit.

## Parameters

- **Key Metric – Shark Net Position Change** ∞ The aggregate change in Bitcoin holdings by [wallets holding 100-1](https://incrypthos.com/security/btcturk-hot-wallets-compromised-via-private-key-exploitation/),000 BTC.

- **Observed Pattern – Record [Accumulation](https://incrypthos.com/news/accumulation/)** ∞ Shark entities have aggressively increased holdings since July 2025.

- **Core Data Point – Total Shark Holdings** ∞ Over 3.65 million BTC, an [all-time record](https://incrypthos.com/insights/bitcoins-new-all-time-high-signals-wealth-transfer-and-euphoria/) high.

- **Recent Accumulation – Last Seven Days** ∞ Nearly 65,000 BTC added to shark [portfolios](https://incrypthos.com/news/portfolios/).

- **Market Impact – Supply Deficit** ∞ [Aggressive buying](https://incrypthos.com/insights/institutional-buying-fuels-ethereums-market-outperformance/) pushed net supply into a deficit state.

## Outlook

This sustained accumulation by mid-sized Bitcoin whales suggests a strong foundation for potential future [price appreciation](https://incrypthos.com/markets/ethereum-spot-etf-inflows-drive-market-structure-rebalancing-and-price-stability/) in the near term. The market appears to be in a phase of strategic supply absorption, which often precedes significant upward moves. A confirming signal to watch for would be Bitcoin successfully breaking through key resistance levels, such as $114,827 and $118,617, potentially opening the path to $120,000-$125,000. Conversely, a counter-signal would be a failure to hold the $113,000 support level, which could indicate a weakening of this bullish conviction.

**Mid-sized Bitcoin investors are accumulating at record rates, signaling robust conviction and a strong bullish outlook.**
