Luxor Commits $100 Million to MicroBT Rigs as Manufacturer Plans Investment in Mining Software Firm

• Luxor has committed $100 million to buy MicroBT’s WhatsMiner rigs, extending a partnership that now spans both hardware procurement and software support.
• MicroBT has also signed a term sheet to invest in Luxor through its investment manager, while Luxor expands LuxOS firmware support for WhatsMiner machines.

Luxor and MicroBT are tightening one of the more practical partnerships in the mining sector, linking capital, hardware supply and operational software in a way that looks increasingly deliberate rather than opportunistic.

According to a statement released Sunday, Luxor has committed $100 million to purchase MicroBT WhatsMiner rigs. At the same time, MicroBT signed a term sheet to invest in Luxor through its investment manager, Inflection Technology Ltd., though the companies did not disclose the size of that planned investment.

The partnership is now extending beyond hardware sales

That second piece matters. Mining equipment manufacturers routinely sign big supply deals, but planned equity or strategic investment ties are rarer and usually signal a longer-term bet on how the buyer fits into the broader mining stack. In this case, Luxor is not just buying machines. It is also becoming more tightly linked to the software and operational layer that helps those machines run more efficiently.

As part of the expanded arrangement, Luxor said it will broaden support for WhatsMiner rigs through LuxOS, its firmware platform. The company said the added software layer will allow MicroBT machines to move beyond their default settings and gain more responsive operating controls.

Firmware control is part of the competitive edge

Luxor said LuxOS can complete power target transitions in 30 to 60 seconds while continuing to hash, a detail that may sound small but matters in markets where miners constantly react to energy pricing, curtailment events and uptime pressure. The firmware is also meant to improve ramp-up times after curtailment, which can have a direct effect on operational efficiency and revenue capture.

The result is a partnership that now reaches across procurement, performance tuning and strategic capital. For a mining industry that has become more margin-sensitive and operationally disciplined, that kind of alignment is not trivial. It suggests both companies see the next phase of competition as being won not only by who ships more rigs, but by who can make those rigs more flexible and profitable once they are switched on.
