Anthropic data center lease at Rockdale (20-year, 191 MW)

Checked on September 16, 2026. The cited source supports part of this claim, but not all of it.

The lease size, term and 2048 end date are stated directly, but the article expressly says the Anthropic identification is an unconfirmed Bloomberg report rather than a confirmed counterparty.

Confirmed in the source:

• Riot Platforms signed a 20-year lease for 191 megawatts of data-center capacity at its Rockdale campus in Texas
• The base lease term runs through June 2048

We could not confirm this from the cited source:

• That the tenant is Anthropic as a confirmed fact — the article says Riot identified the customer only as a 'leading frontier AI lab', that Bloomberg named Anthropic via people familiar with the agreement, and that neither company has publicly confirmed the counterparty

That does not mean it is false — only that this source does not establish it, as of the date above. If we find a source that settles it, we will re-check and update this page.
