## Briefing

On-chain data reveals a significant accumulation trend among mid-sized Bitcoin investors, known as “sharks,” [signaling strong](https://incrypthos.com/markets/metaplanet-boosts-bitcoin-holdings-signaling-strong-corporate-confidence/) conviction and potential for an upcoming bullish market phase. These entities, holding between 100 and 1,000 BTC, have aggressively increased their holdings since July 2025, pushing their total Bitcoin supply to an all-time record high of over 3.65 million BTC. This consistent buying behavior, even as prices rise, indicates a supply contraction that historically precedes major price surges.

## Context

Many market participants wonder if Bitcoin’s recent price movements represent a sustainable rally or a temporary fluctuation. [Investors](https://incrypthos.com/news/investors/) are asking whether major players are re-engaging with the market, or if the current price stability is fragile. This data helps clarify the underlying forces at play.

## Analysis

The “Shark Net Position Change” tracks the monthly change in Bitcoin holdings for wallets owning 100 to 1,000 BTC. A positive change means these mid-sized whales are adding to their positions. A negative change indicates selling. When this indicator shows [aggressive accumulation](https://incrypthos.com/insights/bitcoin-whales-signal-bullish-momentum-through-aggressive-accumulation/), it suggests strong confidence from well-capitalized investors who are buying Bitcoin and holding it for the long term.

Since July 2025, this metric has been significantly positive, with these “shark” entities adding nearly 65,000 BTC in the last seven days alone, bringing their [total holdings](https://incrypthos.com/markets/metaplanet-boosts-bitcoin-holdings-signaling-strong-corporate-confidence/) to an unprecedented 3.65 million BTC. This sustained accumulation creates a supply deficit, where demand outstrips available coins, often leading to upward price pressure.

Detailed white patterns resembling circuit traces are visible on both the blue and white components, suggesting complex internal mechanisms](https://incrypthos.com/wp-content/uploads/2025/09/blockchain-architecture-interoperability-protocols-visualizing-decentralized-ledger-data-flow.jpeg)

## Parameters

- **Key Metric** ∞ Shark Net Position Change

- **Observed Pattern** ∞ Aggressive [accumulation](https://incrypthos.com/news/accumulation/) by “shark” entities (100-1,000 BTC wallets)

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

- **Accumulation Period** ∞ Since July 2025

- **Recent Inflow** ∞ Nearly 65,000 [BTC](https://incrypthos.com/news/btc/) added in the last seven days

- **Key [Price](https://incrypthos.com/news/price/) Level** ∞ Holding above $112,000 support

Its intricate components are precisely interconnected, highlighting sophisticated engineering and design](https://incrypthos.com/wp-content/uploads/2025/09/modular-dlt-framework-enhancing-cross-chain-digital-asset-management.jpeg)

## Outlook

This strong accumulation by [mid-sized whales](https://incrypthos.com/insights/mid-sized-bitcoin-holders-accumulate-record-amounts-signaling-confidence/) suggests a robust foundation for Bitcoin’s price in the near term, with potential for continued upward momentum. The market bias remains bullish as long as Bitcoin holds above the $113,000 support level. A confirming signal to watch is a decisive breakout above the $115,000 resistance, which could pave the way for a rally towards $120,000 to $125,000. Conversely, a sustained drop below $113,000 would indicate weakening bullish conviction.
