Bitcoin mining is going through a structural change due to reduction in network hashrate and capital reallocation by leading players to artificial intelligence. This shift is attributed to geopolitical tensions, tightening mining economics, and development of institutional support of alternative revenue model.
The Bitcoin’s total hashrate has sharply declined in the first few months of 2026, falling nearly 6% following Middle East conflict and around 4% year to date, the first Q1 decline in six years.
Military developments have affected energy infrastructure in Iran, which accounts for approximately 6% to 8% of global mining capacity. As a result, the global hashrate dropped to around 100,000TH/s from 110,000 TH/s in late 2025.
The hashrate decline is not only because of geopolitical circumstances. Mining economics have also deteriorated significantly as production cost for per Bitcoin reached $90,000 and current price is near $67,000, putting pressure on margins.
In response, several major mining companies are moving toward AI data centers and high-performance computing, where revenue streams are somewhat predictable and do not rely on cryptocurrency price cycles.
This transition highlights that there is a fundamental change to how mining infrastructure is changing the role of a facility meant to validate blocks on a blockchain into digital infrastructure.
MARA Holdings sold 15,133 BTC worth around $1.1 billion to finance its AI infrastructure, marking a change in its strategy of accumulating Bitcoin.
Also, Core Scientific acquired a combined $1 billion in financing from JPMorgan and Morgan Stanley to scale operations in data center facilities in various locations across the US.
At the same time, Cipher Mining has entered long-term data center agreements and raised additional capital to support expansion into AI-focused infrastructure.
However, American Bitcoin, supported by the Trump family, continues to accumulate Bitcoin, and currently, it holds 7,000 BTC.
In the past month alone, MicroStrategy has amassed roughly 45,000 BTC, which amounts to nearly 76% of corporate reserve holdings.
In contrast, participation from other corporate buyers has seen a sharp decline, with activity dropping nearly 99% from its peak, indicating a waning broad institutional presence.

Lower growth of hashrate, coupled with capital reallocation points that the sector is shifting from pure mining operations to different infrastructure models.
Concerns about reduced hashrate may improve decentralization by weakening domination from the United States, where large miners represent more than 40% of all mining capacities.
Looking ahead, future hashrate growth will likely depend on BTC’s price recovery. Forecast suggests there is a potential for growth in hashrate to 1.8 zettahash/sec by the end of 2026, but this depends on market conditions.
For now, the industry remains at a stalemate between the old mining economic model and the new AI-based infrastructure model.
