Does Attention Required! have a moat?

Colossus in Memphis went to 100k H100s in 122 days and is expanding toward about 2 GW and 555k GPUs, with a stated goal of 1M. It has so much spare capacity that Anthropic reportedly rents all of Colossus 1 (about 300 MW) for around $1.25B a month.

To cross it: Get gigawatts of power, hundreds of thousands of Nvidia GPUs and the capital to pay for them, which only a few hyperscalers and labs have.

It raised $6B, then $10B at a $200B valuation, then $20B. In February 2026 SpaceX bought it at a combined $1.25T valuation, SpaceX IPO'd in June 2026, and then it bought Cursor for $60B in stock. That pays for quarterly losses of over $1.4B against about $107M in revenue.

To cross it: Raise tens of billions a year and accept losing billions per quarter for years.

Grok is built into X (about 600M MAU), Tesla cars, Starlink support and, since August 2026, Cursor (50k+ businesses, about $3B ARR). Reuters reported its US mobile chatbot share rose from 1.6% to 17.8% in one year, driven by X.

To cross it: Own or partner with a social network, a car fleet and a top coding tool, none of which can be bought by asking.

Elon Musk is the most-followed account on X (likely 200M+ followers) and personally promotes every Grok release. That also helps explain the $0.42 GSA deal and the Defense Department contract.

To cross it: There is no way to copy it. A challenger would need a founder with comparable reach, which no one has.
