U.S.-Listed Bitcoin Miners Command Record 30% Of Global Hashrate

(MENAFN- The Arabian Post)

American publicly traded bitcoin mining companies have reached an unprecedented milestone, now controlling approximately 30% of the total global Bitcoin Network hashrate. This significant increase underscores the growing influence of U.S.-based miners in the Cryptocurrency ecosystem.

The hashrate, representing the total computational power used to mine and process transactions on the Bitcoin network, serves as a critical indicator of the network's security and efficiency. As of mid-March, the Bitcoin network's hashrate averaged 811 exahashes per second , reflecting a 2 EH/s increase in the first two weeks of the month. Notably, U.S.-listed miners have maintained their share at around 30% during this period.

This expansion is particularly remarkable considering that just over a year ago, these companies accounted for approximately 20% of the network's hashrate. The rapid growth can be attributed to several factors:

– Access to Capital: Being publicly listed provides these miners with enhanced access to capital markets, enabling substantial investments in infrastructure and expansion.

– Availability of Resources: The United States offers abundant land and relatively affordable energy resources, essential for the energy-intensive process of Bitcoin mining.

– Aggressive Expansion Strategies: Companies such as IREN , CleanSpark, Riot Platforms, and MARA Holdings have been actively scaling their operations, deploying new mining rigs, and increasing their computational capacities.

IREN, in particular, has been at the forefront of this expansion. Despite reporting a loss of $51.7 million in the first quarter of 2025, the company has ambitious plans to boost its mining power to 50 EH/s in the coming months. This strategy reflects a broader trend among U.S.-listed miners to reinvest earnings into scaling operations, thereby increasing their share of the network hashrate.

However, this rapid expansion has not been without challenges. The average price of Bitcoin declined by approximately 10% in early March, pressuring mining economics. Additionally, the increase in network hashrate has led to heightened competition among miners, further squeezing profit margins. Some companies have responded by stockpiling Bitcoin to navigate these profit squeezes, leveraging the cryptocurrency's price appreciation to bolster their balance sheets.

MARA Holdings exemplifies this trend. The company recently expanded its capacity by acquiring data centers in Ohio, adding a total of 372 megawatts of compute capacity. This acquisition brings MARA's total nameplate capacity to nearly 1.5 gigawatts, positioning it as one of the largest players in the industry. Despite these advancements, MARA reported widening net losses of $124.8 million in the third quarter, highlighting the financial pressures faced by miners amid fluctuating Bitcoin prices and rising operational costs.

The consolidation of hashrate among U.S.-listed miners has broader implications for the Bitcoin network. While increased hashrate enhances network security by making it more resistant to attacks, the concentration of mining power raises concerns about decentralization-a core principle of the Bitcoin ethos. Industry stakeholders continue to debate the balance between operational efficiency and maintaining a decentralized network structure.
