Why It Matters
Riot Platforms signed a contract worth more than the entire company and at midday the entire company was worth about what it was worth on Monday. The lease announced Monday evening covers 191 megawatts at Riot’s Rockdale, Texas campus and carries roughly $9.1 billion of expected revenue through June 2048, according to the company’s own release. Riot’s market capitalization was $7.363 billion at 1:26 p.m. Eastern on Tuesday, per CNBC’s quote page. The contract is 1.24 times the company that signed it.
The tape did the arithmetic in stages. Riot closed Monday at $19.40, down 5.46% before the news, then rose 25.26% in after-hours trading to $24.30, The Block reported at 10:22 p.m. Eastern. It opened Tuesday at $23.57 and touched $23.66, then traded all the way back to $19.40 by early afternoon. Riot has 378.15 million shares outstanding, so the peak added $1.61 billion of market value and the day’s low gave back every dollar of it.
The reason is in the same press release that caused the move. The $9.1 billion is a twenty-year gross figure. Divided across the term it is about $455 million a year, and Riot says the first 96 megawatts arrive in December 2027 with the balance by June 2028. The Market Context reported on August 10 that Intel raised $15 billion of equity while its market value fell $13.6 billion. That was another case where a headline number and the market’s answer to it were measured on different clocks.
The day’s low matched Monday’s close to the cent
CNBC’s real-time quote page listed Riot at $19.47 at 1:26 p.m. Eastern, up 7 cents, with an open of $23.57, a day high of $23.66 and a day low of $19.40. That low is Monday’s previous close exactly. StockAnalysis had shown a low of $19.61 twelve minutes earlier, so the round trip finished inside that window. Volume by then was 50.1 million shares, about 13% of the shares outstanding.
Published percentages this morning ranged from 14% to 25%, and the spread has a mechanical cause rather than an editorial one. Each outlet timestamped a different minute of a tape that travelled from $24.30 to $19.40 in fifteen hours. The Block wrote 25.26% late on Monday evening, Benzinga wrote 22.68% at $23.80 before the open, and 24/7 Wall St. wrote 17% at $22.64 just after the bell. Invezz wrote about 14%, and all four are accurate readings of different moments.
Riot published enough to price both of its leases, and the second costs three times as much to build
The company now has two tenants at Rockdale and has published the economics of each. Benzinga published Riot’s figures for the fully deployed 50-megawatt AMD lease. They come to about $63.6 million of average annual revenue and $51 million of annual net operating income, on roughly $170.2 million of capital spending. That is $1.27 million of rent per megawatt per year and $3.4 million of capital cost per megawatt.
The new lease runs at $2.38 million per megawatt per year on the company’s $9.1 billion over twenty years, which is 87% more rent for each megawatt. The capital cost moves further. Riot estimates development at $2.1 billion to $2.3 billion, or $11 million to $12 million per critical IT megawatt, which is more than three times the AMD figure per megawatt. Riot describes the new capacity as a build-to-suit Tier 3 data center in its release, while the AMD megawatts sit at a campus that was already energized.
Run those against Riot’s own net operating income estimates and the two leases separate. AMD’s $51 million of annual NOI against $170.2 million of capital is a 30% annual return on cost. The new lease’s $365 million to $411 million of annual NOI against $2.1 billion to $2.3 billion of capital lands between 15.9% and 19.6%. Both figures are Riot’s estimates and both carry the construction and financing risks the company lists in its release.
Riot has never named Anthropic and the document describes a lease, not a compute contract
Every headline on Tuesday carried the word Anthropic. Riot’s release does not. The company describes the tenant only as “one of the world’s leading frontier AI labs” across the entire document. Bloomberg identified the counterparty as Anthropic on Tuesday, and Quartz, The Block and 24/7 Wall St. each attributed the name to that Bloomberg report rather than to Riot.
The instrument matters as much as the name. Riot calls it a “Data Center Lease and Services Agreement” and books the AMD equivalent as operating lease revenue and tenant fit-out services revenue, $4.9 million and $18.3 million respectively last quarter. Several outlets described Tuesday’s news as a cloud or compute deal. A lease means Riot supplies powered capacity and the tenant supplies the computers, which puts the hardware cycle on the other side of the contract.
The peers that were supposed to re-rate moved about two percent
If a landmark AI lease revalued the whole cohort of bitcoin miners turned data center operators, the read-through would show up in the neighbours. It did not. 24/7 Wall St. reported IREN, Applied Digital and TeraWulf each up 2% on Tuesday morning. The Global X Data Center and Digital Infrastructure ETF was up 1% at $28.25, which is the read-through priced by a fund rather than by one ticker. The Market Context reported on July 20 that IREN signed $2.8 billion of AI cloud contracts and lifted its 2026 target to $4 billion. This cohort has been signing very large numbers all summer.
Riot’s second-quarter results landed in the same release. Revenue rose 14% to $174.2 million against a $152.88 million consensus cited by TheFly. The company swung to a net loss of $237.2 million from net income of $219.5 million a year earlier. Adjusted EBITDA was negative $69.7 million against positive $495.3 million. Data center revenue of $23.2 million annualizes to $92.8 million, which the new lease would multiply by about five once fully delivered. AMD is the tenant on the first lease and also, as The Market Context reported on July 28, took a 30 million share warrant in its Core Scientific deal.
What to watch
1. Riot’s third-quarter results, due around early November. The line to read is Data Center segment revenue, and specifically the split between recurring operating lease revenue and one-time tenant fit-out services. That split was $4.9 million against $18.3 million in the second quarter.
2. The Form 10-Q for the quarter ended September 30. The line to read is the disclosure on the $573 million Morgan Stanley interim facility and whether the investment-grade credit backstop Riot says it is finalizing has been executed.
3. Riot’s November 2026 delivery milestone for the 10-megawatt AMD Phase 3 expansion. The company committed to that date in the second-quarter release, and it is the first checkable test of the delivery schedule that the December 2027 date depends on.
4. Any 8-K naming the Corsicana tenant. CEO Jason Les said on the earnings call that the 1-gigawatt site is under a non-binding letter of intent with a single tenant for the whole campus. A signed lease would be filed rather than described.
