SBI Crypto, the digital asset company owned by Japan's SBI Holdings, will close its bitcoin mining pool at the end of July after running it for about five years.

The company said the mining pool will officially shut down on July 31, 2026. It will stop accepting mining shares at 22:00 UTC on July 30. This gives miners about one month to move to another mining pool.

SBI Crypto did not say why it decided to close the service.

In the message to customers by CEO Hiroaki Morita, the company asked miners to keep using the pool until the final deadline. This will help make sure everyone's mining rewards are counted correctly before the service ends.

The company also thanked its customers, saying it would "sincerely appreciate your continued support by mining with us until the final day of operation."

SBI Crypto started its bitcoin mining pool in 2021 after already running its own digital assets mining operations overseas.

Over the years, the pool grew into one of the largest in the world. Data shows it handled between 20.9 EH/s and 21.46 EH/s of computing power, or about 2.2% of the entire Bitcoin network. It ranked around 12th among all bitcoin mining pools.

Even so, back in the day, it was still much smaller than the biggest mining pools, such as Foundry USA and AntPool, which control much larger shares of the Bitcoin network.

Earlier data from late 2025 showed the pool had about 15 EH/s, equal to roughly 1.3% of the network. This shows the pool's share changed over time. The pool is currently the 29th largest pool by block share, securing only 0.48% of all mined blocks, according to mempool.space.

To help customers prepare for the shutdown, SBI Crypto suggested several other mining pools, including Braiins, Luxor Pool, and NeoPool.

The company said it had spoken with these operators before, but it was not recommending any one of them. Instead, miners should contact the companies themselves and choose the one that best meets their needs.

SBI Crypto also said some mining pools may offer special deals or benefits to customers moving from its service.

"Some operators may offer special programs or preferential conditions for clients transitioning from SBI Crypto," the company said.

Another company, OCEAN Mining, also invited SBI Crypto customers to join its mining pool. OCEAN said its payment system gave miners better returns than some traditional mining pools during 2025. It also promoted its DATUM system, which gives miners more control over how they receive rewards.

SBI Crypto said the mining pool should continue working normally until it closes. Mining rewards will also continue to be paid as usual. The company said it will later announce more details about the final payouts, API access, website availability, and other steps related to closing the service.
