Antpool overtakes Foundry as largest bitcoin mining pool
Antpool, a Singapore-headquartered open access mining pool that supports ten cryptocurrencies, has recently surpassed Foundry USA to become the foremost bitcoin mining pool in terms of monthly blocks mined.
That’s according to a report published by TheMinerMag, a bitcoin mining industry publication run by New York public relations firm BlocksBridge Consulting.
This development indicates a shift in bitcoin mining pool dynamics since January 2022. According to Bitcoin network data, Antpool mined 1,219 blocks in November, slightly edging out Foundry USA’s 1,216 blocks. The total rewards for Antpool’s miner clients reached 8,672 BTC, excluding the 83.6 BTC designated for refunds.

Bitmain affiliate
AntPool is an affiliate company of leading crypto mining equipment manufacturer, Bitmain. This surge in Antpool’s hashrate aligns with Bitmain’s substantial importation of over 4,800 metric tons of Antminer S19XP and S19XP Hydro to its U.S. subsidiary in Georgia between June and November. These imports have contributed to an estimated total hashrate exceeding 37 EH/s. The exact activation status of Bitmain’s imported hashrate and whether it is utilized for its own purposes, remains unclear.
Foundry USA had previously held the leading position in mining pools since early 2022, benefiting from the rise of North American mining operations following China’s crackdown in 2021. While Antpool consistently secured the second position, its hashrate began closing the gap on Foundry USA around June this year.
China vs. U.S. competitive dynamic
The two companies dominate bitcoin mining. With one having a parent company headquartered in China and the other being U.S.-centric, their positioning in terms of overall blocks mined is being seen by some as a reflection of competition between entities in China and the United States in terms of bitcoin mining dominance. Addressing that dynamic in response to CoinDesk recently, CryptoQuant Web3 Analyst Bradley Park wrote:
“China is aggressively mining ahead of the approval of a Bitcoin ETF. As the Bitcoin halving nears, I anticipate a competitive surge between China and the US in mining machine productivity. This is because the unit cost of mining Bitcoin is likely to escalate due to increasing power expenses and rising mining difficulty.”
The bitcoin hashrate has been climbing continuously throughout 2023, reaching new all-time highs along the way.
It’s worth noting that despite Antpool’s dominance in blocks mined, data from BTC.com reveals that the company’s self-reported real-time hashrate consistently lags behind Foundry USA’s over the past three months. The cause of this discrepancy remains uncertain, raising questions about variance or reporting errors affecting Antpool’s real-time hashrate.
Bitmain established Antpool in 2014, and it was later spun out of Bitmain to become an independent entity in 2021. Meanwhile, Foundry is a wholly owned subsidiary of Digital Currency Group (DCG). Both Bitmain and DCG have been facing financial challenges over the course of the past year.
In a separate development, Foundry took to social media platform X on Thursday to confirm that it is discontinuing support for The Graph protocol, Axelar Network, Polkadot and Flow. The firm said that the changes were decided upon in order to better align the business with its strategic business goals.
