Blockstream Raises $210M, Acquires Mining Chip Manufacturer Spondoolies
The Series B round values Adam Back's Bitcoin technology firm at $3.2 billion.
Blockstream has raised $210 million in a Series B funding round that values the bitcoin technology firm at $3.2 billion and will fund an expansion into manufacturing mining chips.
U.K. investment management firm Baillie Gifford and iFinex, the parent company of cryptocurrency exchange Bitfinex and stablecoin issuer Tether, participated in the round, Blockstream said Tuesday. No other investors were mentioned.
Blockstream also said it had acquired the intellectual property and key employees of Israeli bitcoin mining hardware manufacturer Spondoolies for undisclosed terms.
The move paves the way for Blockstream, based in Victoria, British Columbia, to build out a business line making specialized mining chips known as ASICs, the Canadian company said.
The acquisition, together with the additional funding, will advance Blockstream’s crypto mining products and services, including its recently announced Blockstream Energy service.
The new capital will also further the firm's Bitcoin-focused financial products as well as its Liquid sidechain network, according to the company.

ASIC ambitions
Now is a "most opportune time" to accelerate growth, Blockstream Chief Strategy Officer Samson Mow told CoinDesk via Telegram on Monday.
"The fresh infusion of capital will allow us to launch more products under Blockstream Finance, as well as bring our new bitcoin ASIC miner to market next year," said Mow.
Blockstream was founded in 2014 with a focus on building infrastructure and applications based upon the Bitcoin network. The firm was co-founded by CEO Adam Back (inventor of Hashcash, a system for discouraging spam emails that influenced Satoshi Nakamoto's proof-of-work consensus mechanism design for Bitcoin) and nine others, including Bitcoin Core developer Gregory Maxwell.

The firm's Series A round, completed in 2016, was led by AXA Strategic Ventures, the venture capital arm of French multinational insurance firm AXA Group; Digital Garage, the Tokyo-based online payments firm co-founded by Joi Ito; and Hong Kong VC firm Horizons Ventures. AME Cloud Ventures, Blockchain Capital and Future\Perfect Ventures also participated in that earlier round.
UPDATE (Aug. 24, 14:00 UTC): Correct's Mow's title.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
