In 2018, three leading cryptocurrency mining hardware manufacturers—Bitmain, Canaan Creative, and Ebang International—filed for initial public offerings (IPOs) on the Hong Kong Stock Exchange. This marked a pivotal moment in the blockchain industry, potentially ushering in the first wave of blockchain startups going public since Satoshi Nakamoto introduced Bitcoin in 2009. These companies, all specializing in the design and sale of ASIC-based mining rigs using a fabless semiconductor model, represent the cutting edge of blockchain infrastructure.
While Bitmain emerged as a dominant player—ranking among China’s top two chip designers by revenue in 2017 according to ICWise—the race to become the world’s first publicly listed blockchain firm intensified competition across technical innovation, financial performance, and strategic diversification.
The Rise of ASIC Mining: A New Era in Computing
Application-Specific Integrated Circuits (ASICs) are custom chips engineered for a single purpose—in this case, cryptographic hashing used in blockchain mining. Unlike general-purpose processors, ASICs offer superior efficiency in terms of power consumption, speed, and cost at scale. As Bitcoin and other proof-of-work cryptocurrencies gained traction, demand surged for high-performance mining hardware, creating a booming market dominated by Chinese firms.
According to Frost & Sullivan, the global ASIC chip market reached $25.7 billion in 2017 and is projected to grow at a compound annual growth rate (CAGR) of 18.4%, hitting $59.7 billion by 2022. This surge is fueled not only by cryptocurrency mining but also by emerging applications in artificial intelligence (AI), where specialized chips deliver unmatched computational throughput.
The fabless model adopted by Bitmain, Canaan, and Ebang allows them to focus on chip design and system integration while outsourcing fabrication to foundries like TSMC. This lean approach enables rapid iteration and scalability without the capital burden of owning semiconductor plants.
Market Leadership: A Triopoly Takes Shape
The Bitcoin mining hardware landscape is characterized by a near-monopoly held by three key players. Data from iResearch indicates that together, Bitmain, Canaan Creative, and Ebang International controlled approximately 88% of the global Bitcoin mining hardware market in 2018.
Bitmain: The Early Dominator
Founded in 2013, Bitmain quickly rose to prominence with its Antminer series, leveraging energy-efficient designs during periods of market volatility. By 2017, it generated $16.45 billion in revenue**, a staggering 806.79% year-on-year increase, with net profits reaching **$4.58 billion—over ten times higher than its closest competitors.
Its Antminer S9, launched in 2016 using 16nm process technology, became the industry standard for years. However, its dominance began to waver due to delayed product cycles and shifting R&D priorities toward AI.
Canaan Creative: Innovation Through Miniaturization
Established in 2013 by Zhang Nangeng, Canaan Creative pioneered early ASIC integration in mining devices. In 2018, it achieved a major breakthrough by mass-producing 7nm ASIC chips, giving its AvalonMiner series a significant edge over rivals still using older nodes.
This technological leap allowed Canaan to offer higher hash rates with lower power consumption—critical metrics in an industry where electricity costs can make or break profitability. While its 2017 revenue stood at $130.8 million, its return on equity (ROE) and return on assets (ROA) showed consistent upward trends, signaling strong operational efficiency and future growth potential.
Ebang International: From Telecom to Blockchain
Originally focused on telecom equipment for carriers like China Mobile and China Unicom, Ebang International pivoted to blockchain in 2014. It launched its first proprietary miner, the E9, in 2016 and delisted from China’s NEEQ in 2018 to pursue a Hong Kong IPO.
Though smaller in scale—with 2017 revenues of $97.8 million—Ebang demonstrated agility in transitioning its business model. Its BPU series miners contributed to over 94% of revenue by 2017, reflecting a successful strategic shift.
Financial Performance and Profitability Trends
Despite varying revenue scales, all three companies reported healthy gross margins exceeding 40%, underscoring the profitability of ASIC mining hardware when demand aligns with bull markets.
| Company | 2017 Revenue (USD) | Net Profit (USD) | Gross Margin | ROE Trend |
|---|---|---|---|---|
| Bitmain | $16.45 billion | $4.58 billion | ~45% | Declining |
| Canaan | $130.8 million | $36.1 million | Rising | Improving |
| Ebang | $97.8 million | $38.5 million | Stable | Recovering |
Bitmain’s declining ROE and ROA were attributed to increased debt financing in 2017, which raised financial leverage. Meanwhile, Canaan’s steady improvement in profitability metrics positioned it favorably despite lower absolute earnings.
Revenue streams remain heavily concentrated on hardware sales:
- Bitmain: 89.89% from miners, down from diversified income including self-mining.
- Canaan: Transitioned from chip sales (25% in 2015) to nearly 100% miner sales by 2017.
- Ebang: Shifted from 68.3% telecom revenue in 2015 to 94.56% blockchain-related income by 2017.
Research & Development: The Race for Process Node Supremacy
In the fast-evolving world of semiconductor design, time-to-market is everything. The typical ASIC mining chip lifecycle ranges from six months to one year, demanding relentless R&D investment.
- Bitmain spent $470 million on R&D in 2017—the highest among peers—but this represented less than 5% of total revenue, indicating relatively restrained reinvestment.
- Canaan increased its R&D spend from $5 million in 2015** to **$100 million in 2017, achieving a faster growth rate than both Bitmain and Ebang.
- Ebang maintained moderate R&D expenditure but lagged behind in process node advancement.
Critically, Bitmain’s failure to release a successor to the S9 for two years exposed vulnerabilities. Competitors like Canaan’s Avalon and MicroBT’s WhatsMiner introduced more efficient models with sub-70W/T power efficiency ratios—far surpassing the S9’s 104W/T benchmark.
This stagnation highlighted a strategic trade-off: Bitmain redirected resources toward AI development, launching chips like the BM1682 for image recognition and big data analytics.
Strategic Diversification: Mining Firms Turn to AI
Facing volatile crypto markets and regulatory uncertainty, all three companies have pursued AI as a long-term hedge against cyclical downturns.
