Elon Musk just spent millions painting “MACROHARD” on a supercomputer facility to troll Microsoft from space. But the real story is even wilder.

On October 14, 2025, at 7:18 AM, Musk tweeted “Logo complete” with an aerial photo showing “MACROHARD” painted across the roof of xAI’s massive Colossus II facility in Memphis, Tennessee. Within hours, it had 19 million views.

This isn’t just expensive trolling. It’s the physical manifestation of a $10 billion AI war that started with a joke and evolved into a direct assault on Microsoft’s software empire.

THE COMPLETE TIMELINE OF CHAOS:

October 2021: Musk tweets “Macrohard >> Microsoft” as a throwaway joke

July 14, 2025: Announces plans for a “multi-agent AI software company” under xAI

August 22, 2025: Officially launches Macrohard as a “purely AI software company,” calling the name “tongue-in-cheek” but the project “very real”

September 2025: Announces plans to paint “MACROHARD” on the roof of xAI’s Colossus II supercompute cluster in Memphis, “making it visible from space”

September 29, 2025: Microsoft announces partnership with xAI to integrate Grok 4 into Azure AI Foundry (yes, while being trolled)

October 14, 2025: Completes the giant roof logo at the Memphis facility
