On the recordSince 26 July 2026 · Checkable from Q3-Q4 2026 · Every call on the record Checkpoint: MicroBT expected to ship M79S/M7x chips at competitive efficiency
The call

MicroBT sits in a tight three-way chip race where Bitmain currently ships the faster hardware, while U.S. capital rules and tariffs squeeze its room to catch up.

MicroBT makes specialized computer chips that solve math problems to mine Bitcoin. It is hard to replace because only three companies in the world make these chips well enough to matter, and MicroBT has customers who promised to buy $230 million worth. However, Bitmain, the #1 competitor, is already shipping newer, better chips while MicroBT's new chips are announced but not yet in customers' hands. Three things could shake the business: tariffs making U.S. factories less attractive, the U.S. government restricting sales to China companies, or Bitcoin's price dropping so people stop mining. The one thing that matters most is whether MicroBT can ship its new M79S and M7x chips before Bitmain pulls too far ahead in the race to make the most efficient chips.

Why
01
AI pressure: AI chip demand for TSMC leading-edge capacity. Nvidia and other AI chipmakers compete with MicroBT for the same advanced TSMC wafer slots, risking delays to its next chip generation. Could AI do the core job? Unlikely.
02
Bigger players: Bitmain (Antminer S23 Hyd). Bitmain is already shipping its S23 Hyd at 9.5 J/TH while MicroBT's rival M79S/M7x chips remain announced but undelivered. Could a giant copy it? Yes, easily.
03
What protects it. Over $230M in signed Whatsminer orders from Luxor plus a three-way oligopoly structure that keeps new entrants out of chip design and fabrication access.
What would change this call
MicroBT confirms an M79S/M7x ship date and matches or beats S23 Hyd efficiency by Q3/Q4 2026. Shows whether MicroBT can defend its #2 position against Bitmain's product lead.
Auradine ships its sub-10 J/TH Teraflux miner on schedule in Q3 2026 and wins U.S. orders. Would indicate a fourth player fracturing the triopoly and squeezing MicroBT's middle position.
U.S. regulators (SEC/Nasdaq/Congress) impose a blacklist or export restriction naming MicroBT or its Whatsminer line. Would confirm geopolitical scrutiny is directly cutting off MicroBT's U.S. capital or sales access.
Key numbers
  • Luxor committed $131.4M for Whatsminer rigs (2024-12-11)
  • Luxor added $100M more in orders (2026-04-26)
  • Top 3 makers held 95.4% of ASIC hashrate sold (2023-12-31)
Named risks
  • Tariff escalation on Southeast Asian imports eroding MicroBT's US assembly workaround. Severity: high
  • Escalating US regulatory and capital-market restrictions targeting Chinese tech firms. Severity: high
  • Product-cycle lag: M79S/M7x unshipped while Bitmain's S23 Hyd already leads on efficiency. Severity: medium
  • Prolonged weak bitcoin hashprice/margin environment cited in April 2026 Luxor deal. Severity: medium
  • Unverifiable revenue and headcount data with thin, largely undisclosed funding history. Severity: low

Questions people ask
Is MicroBT profitable in 2026?
No audited financials are public. MicroBT is privately held and discloses no revenue or profit figures. The only public financial signals are customer purchase deals, like Luxor Technology's $131.4M rig commitment in December 2024, expanded by another $100M in April 2026, not company-reported earnings.
Who owns MicroBT?
MicroBT (legally Shenzhen Bit Microelectronics Technology Co., Ltd.) is privately held. Founder Yang Zuoxing, a former Bitmain chip-design director who started the company in 2016, remains majority shareholder and serves as Chairman, CEO, and GM as of the most recent reporting in 2019 court coverage.
Could AI replace MicroBT?
No. MicroBT designs and sells physical Bitcoin ASIC hardware (Whatsminer) tied to the SHA-256 algorithm, a product category generative AI cannot substitute directly. The only indirect AI risk is foundry capacity competition, if AI chip demand crowds out MicroBT's 5nm wafer allocation at partners like Samsung.
Who is MicroBT's biggest competitor?
Bitmain (Antminer brand) is MicroBT's dominant rival. As of July 2026, Bitmain is already shipping its next-gen S23 Hyd 3U at 9.5 J/TH efficiency, while MicroBT's comparable M79S/M7x line remains announced-only with no confirmed ship date, per an July 7, 2026 industry roundup.
Is MicroBT going public or listing on Nasdaq?
No listing has been announced. Since May 17, 2026, SEC-approved Nasdaq rules require China-based companies to raise at least $25M with extra scrutiny to IPO, and by July 17, 2026 US lawmakers were pushing to further restrict Chinese firms' access to US capital markets.
How big is MicroBT compared to Bitmain and Canaan?
As of December 31, 2023, Frost & Sullivan estimated MicroBT, Bitmain, and Canaan together controlled 95.4% of global ASIC hashrate hardware sold, with MicroBT ranked #2 or #3. In 2019 MicroBT sold roughly 600,000 M20-series units, about 30 to 40% of new hashrate deployed that year.
