In 2026, Foundry USA has emerged as the leading Bitcoin mining pool, commanding approximately 30% of the global hash rate, according to a report by Hashrate Index. The report highlights the evolution of mining pools from simple tools for aggregating hash power and smoothing income volatility to sophisticated hubs integrating firmware, mining management software, energy optimization systems, and financial markets. The report notes that with the influx of institutional capital and increased demands for compliance and settlement certainty, leading mining pools have adopted fixed or prepaid settlement models. This approach transforms future hash rate output into predictable cash flows, altering the financing and management of mining operations. Following Foundry USA, other top mining pools include AntPool, ViaBTC, and F2Pool.
