There appears to be a structural shift underway among Bitcoin [BTC] Miners, who play a crucial role in securing the network, become vulnerable because some of their computing power is sent elsewhere.
The rapid expansion of artificial intelligence, which accounted for nearly 80% of venture capital funding totaling $242 billion in early 2026, in addition to growing demand for data centers, may have contributed to this trend. However, this does not necessarily mean that miners have turned bearish on BTC.
The hash rate records a rare contraction
Bitcoin’s hash rate fell in the first quarter, marking its first negative growth period in more than five years.
On an annual basis, the network’s hash rate has dropped by about 4% at the time of writing, indicating a reduction in the overall computing power securing the blockchain. This slowdown is consistent with a broader turnaround in the sector.
Notably, several mining companies have started reallocating infrastructure towards AI-focused data processing, with demand and price dynamics remaining strong.
For many operators, this transition provides practical protection against the tightening mining margins that have persisted since the fourth quarter of 2025, when the market fell. Instead of relying solely on block rewards and transaction fees, miners are diversifying into computer leasing and AI data services.
The shift is no longer isolated. Companies like Riot platforms, IREN, Bit farms, TeraWulfAnd Marathon digital holdings have all taken steps to expand into AI and high-performance computing. Their positioning reflects a calculated response to rising demand for AI infrastructure rather than a retreat from Bitcoin itself.
Miners are holding firm despite the shift
Even as computing resources are diverted, miners’ behavior in the marketplace tells a more measured story.
According to CryptoQuant, the Bitcoin Miner Position Index (MPI), which compares miner outflows to the one-year moving average, has fallen to -1.2 at the time of writing. A negative MPI value indicates that miners are selling less than normal. In practical terms, this indicates reduced distribution and a preference for holding mined Bitcoin.
This trend becomes clearer when we look at miners’ reserves. The total amount of Bitcoin held by miners has increased, reinforcing the view that accumulation remains intact.
As of April 19, miners’ reserves amounted to approximately 1.8 million BTC. In dollar terms, this amounts to approximately $140 billion, the highest level since February 2, 2026.
Such accumulation generally reflects expectations of future price strength. Rather than exiting their positions, miners appear to be maintaining their exposure while adjusting their operating strategy.
Broader market flows support the outlook
Miner activity represents just one layer of the Bitcoin market structure. Broader capital flows continue to provide additional context.
At the time of writing, spot exchange data showed approximately $120 million in net Bitcoin purchases. This signals a return of buying interest after four days of selling pressure.
Institutional activities further reinforce this trend. On May 1, major investors made one of their largest Bitcoin purchases of the year, betting around $629 million.
This move also generated a series of consecutive weekly inflows, underscoring continued institutional participation.
Final summary
- Bitcoin’s hash rate has fallen, marking a negative year-over-year change as miners divert their computing power to AI infrastructure.
- Miner reserves have risen to $140 billion, the highest level since February 2026, indicating continued accumulation.
