Bitcoin News Today: Bitcoin hashrate surges to record 955.75 EH/s driven by global mining expansion and AI optimization

Bitcoin’s hashrate surged to an unprecedented 955.75 EH/s between July 27-28, 2025, marking a pivotal milestone in the network’s operational scale. This record was driven by a global expansion of mining infrastructure, with North American and Central Asian initiatives playing a central role. Companies such as Core Scientific and CoreWeave integrated artificial intelligence with mining operations to optimize efficiency, while Cipher Mining announced further expansion plans. Michael Levitt, CEO of Core Scientific, emphasized that these advancements “strengthened the network’s security” by leveraging AI-driven infrastructure upgrades [1]. The surge underscores a growing trend of aligning computational demands with energy-efficient mining strategies, particularly in regions with access to renewable power sources.

The hashrate’s trajectory has coincided with heightened institutional interest. Entities like Marathon Digital and Riot Platforms have invested in energy-efficient hardware, reflecting confidence in Bitcoin’s long-term viability. Fred Thiel, CEO of Marathon Digital, described the initiative as a strategic move to enhance operational efficiency and network resilience [1]. Meanwhile, institutional adoption expanded, with firms such as MicroStrategy and Metaplanet accumulating over 1,000 BTC each as reserve assets. Open interest in Bitcoin futures reached a record $44.5 billion in July 2025, signaling increased speculative activity despite market volatility [5].

However, the record hashrate has also intensified competition and energy demands. Network difficulty climbed to 126 trillion in June 2025, compelling miners to allocate more computational power and energy to validate blocks. BitFuFu, a mining firm, demonstrated this trend by achieving 36.2 EH/s while consuming 728 megawatts of power in June [2]. Such energy consumption highlights the industrial-scale operations now dominating the sector. In Texas, miners temporarily curtailed energy use during peak demand periods to avoid higher costs, briefly disrupting block production [1].

The interplay between hashrate growth and Bitcoin’s price dynamics remains complex. While the asset’s price approached $123,000 in July 2025, trading volumes experienced a downturn, indicating potential market challenges [1]. Analysts note a possible correlation between the hashrate’s rise and price movements, such as Bitcoin’s all-time high of $93,000 in July 2025. However, market forces—including regulatory developments and macroeconomic factors—remain multifaceted [3].

Smaller miners face increasing pressure as large-scale operations leverage economies of scale and energy efficiency. Despite this, the network’s decentralized nature persists, as evidenced by a solo miner securing a block in July using 2.3 petahashes—a rare achievement in an increasingly centralized landscape [1]. To offset shrinking profit margins, corporate miners are diversifying into adjacent industries, such as AI data centers and high-performance computing, to capitalize on cross-industry synergies.

The record hashrate highlights Bitcoin’s evolving role as both a financial asset and a robust infrastructure. Strengthened network security and institutional backing position the cryptocurrency for broader integration into global financial systems. Yet, sustainability and regulatory frameworks remain critical challenges. As the block subsidy continues to halve, miners must balance energy consumption, technological innovation, and profitability to sustain operations in a competitive market [1].
