The short answer
Texas hosts the largest concentration of industrial Bitcoin mining in the United States. The biggest sites are Riot's 700 MW Rockdale facility in Milam County — the largest in North America — Riot's Corsicana campus, MARA's Granbury mine, and Hut 8's 280 MW King Mountain site. Several former Bitcoin mines, led by Galaxy's Helios campus, are now converting to AI data centers, and the same operators are building AI-native campuses like Hut 8's 1 GW Beacon Point beside them.
Key facts
- Riot's Rockdale facility has 700 MW of developed capacity — the largest single Bitcoin mining facility in North America.[1]
- Riot's Corsicana campus has a full gigawatt approved by ERCOT, with 400 MW mining Bitcoin and the remaining 600 MW under AI/HPC evaluation since 2025.[2]
- On July 6, 2026, Galaxy delivered the first 133 MW of its former Helios Bitcoin mine to CoreWeave under a 15-year, 526 MW AI lease.[11]
- MARA bought its Granbury mine in January 2024 as part of a $178.6 million, 390 MW two-site acquisition from Generate Capital.[6]
- In August 2023, ERCOT paid Riot $31.7 million in power credits to curtail mining during the Texas heat wave.[17]
- By August 2026, ERCOT's interconnection queue had reached about 474 GW — roughly 90% data centers — and the state ordered an audit that paused new large-load classifications.[20]
Riot Rockdale (Whinstone)
Rockdale · Milam County · online 2020
700 MW developed · 241 MW IT contracted · Mining + AI/HPC pivot underway
The flagship, now living its own third act. Built by Whinstone on the grounds of Alcoa's shuttered aluminum smelter, acquired by Riot in May 2021 for roughly $651 million, and expanded to 700 MW — the largest single Bitcoin mine in North America. In 2026 the AI turn reached it: AMD signed as first data-center tenant in January (50 MW contracted), and on August 10 Riot announced a 20-year, 191 MW lease with a leading frontier AI lab worth $9.1 billion over the initial term. The mine still hashes while the campus converts.
What does this map show?
This map tracks 13 of the most consequential industrial sites in Texas's Bitcoin-and-AI power story — the operating mines, roughly 2.8 GW of developed capacity and more than 4 GW counting ERCOT-approved expansion, plus the miner-built AI campuses now rising beside them. Every capacity figure is the operator's own published number or reputable trade-press reporting, cited below. Smaller and off-grid operations — including the flare-gas miners of the Permian Basin — aren't pinned here, so treat this as the industrial backbone, not a census. The dataset was last verified August 30, 2026, and we re-verify it quarterly alongside the history of Bitcoin in Texas.
Where are the biggest Bitcoin mines in Texas?
The biggest Bitcoin mines in Texas are Riot's Rockdale facility (700 MW developed) and Corsicana campus (400 MW mining, 1 GW approved), MARA's Granbury site (~300 MW), Cipher's Black Pearl (300 MW) and Odessa (207 MW), and Hut 8's King Mountain (280 MW).[1][2][9][12] Rockdale is where the industrial era began: Bitmain broke ground on the former Alcoa aluminum smelter land in 2019, Whinstone built the giant next door, and Riot bought it in May 2021 for roughly $651 million.[3][4] One town in Milam County — hollowed out when the smelter closed — became the mining capital of the Western Hemisphere.
Why is Bitcoin mining concentrated in West Texas?
Because that's where the stranded power is. West Texas generates enormous wind and solar output that transmission lines can't always carry to the cities, and miners are the buyers of last resort for those electrons. Hut 8's King Mountain site sits directly beside a wind farm on a mesa outside McCamey.[12] Layer1 proved the model first: in February 2020 — before Riot, before China's ban — the Peter Thiel-backed startup was mining in liquid-cooled containers off its own 100 MW substation in Ward County, powering down to sell energy back when prices spiked.[15][16] That playbook — mine cheap, curtail high — became standard practice through ERCOT's demand response programs, which pay large loads to power down when the grid is stressed.[17]
Why are Bitcoin mines turning into AI data centers?
Because the scarcest resource in computing is no longer chips — it's connected power, and miners spent a decade accumulating it. Galaxy bought the distressed Argo Helios mine in Dickens County for $65 million in December 2022; on July 6, 2026, it delivered the first 133 MW to CoreWeave under a 15-year lease projected to generate over $1 billion a year at full buildout.[11] Core Scientific is converting its Denton campus in a $6.1 billion buildout.[13][14] Cipher's brand-new Black Pearl site leased straight to Amazon.[10] ERCOT's interconnection queue swelled from roughly 226 GW in early 2026 to about 474 GW by that August — most of it AI — enough to force the state's hand.[19][20] This is not Bitcoin losing to AI — it's the infrastructure Bitcoin built becoming the on-ramp for the next compute frontier, while mining stays the anchor tenant at sites like Rockdale.
What did Texas's August 2026 data-center audit change?
On August 4, 2026, Governor Greg Abbott ordered the Public Utility Commission and ERCOT to audit every data-center project in the state's interconnection queue, and ERCOT paused “Batch Zero,” the first classification of its largest new loads.[20] The queue had swelled to roughly 474 gigawatts of requests — about 90% of it data centers — a figure no grid can physically build, so the audit is Texas sorting the real projects from the speculative ones. For the sites already on this map, that reframes the whole board: an ERCOT-approved interconnection stops being paperwork and becomes the moat. As Bernstein put it, “if MWs are scarce, it makes sense to earn more per MW” — and the operators with power already in hand, Riot's 700 MW at Rockdale and its approved gigawatt at Corsicana among them, are the ones holding it.[20]
What the audit is now screening is a Texas land-grab for miner-built AI capacity. Hut 8 has fully contracted its 1-gigawatt Beacon Point campus in Nueces County to a single high-grade tenant — reported to be Nvidia — across two 15-year, 352 MW leases worth $19.6 billion.[21] Cipher leased the entirety of its 300 MW Barber Lake site in Mitchell County to Fluidstack in a roughly $3 billion deal that Google agreed to backstop.[23] MARA signed to acquire a Matagorda County site carrying up to 2 GW of power for a campus that will blend high-performance computing with flexible Bitcoin mining, paying out as milestones — grid authorization among them — are met.[22] Even Bitdeer has flagged its Rockdale campus as a candidate for AI/HPC conversion in its operations updates.[24] This is why we keep the mining map and the grid in the same frame: the machines Bitcoin installed are why Texas is now the front line of the AI power crunch — and why the state just hit pause to take inventory.
The counterweight: Granbury's noise fight
The record isn't all triumph, and we keep the hard parts in. MARA's Granbury mine runs behind-the-meter at the 1,115 MW Wolf Hollow gas plant, and its cooling fans have made it the most litigated Bitcoin site in Texas: neighbors report sleep disruption and hearing problems, a Hood County constable issued 37 noise citations, and residents have filed nuisance suits in both state and federal court.[7][8] How MARA answers — with sound walls, immersion cooling, or a settlement — will shape how close to homes the next generation of sites gets built.

Riot Rockdale (Whinstone) · Riot Platforms
Rockdale · Milam County · online 2020
700 MW developed · 241 MW IT contracted · Mining + AI/HPC pivot underway
The flagship, now living its own third act. Built by Whinstone on the grounds of Alcoa's shuttered aluminum smelter, acquired by Riot in May 2021 for roughly $651 million, and expanded to 700 MW — the largest single Bitcoin mine in North America.

The mine still hashes while the campus converts. [1][3][25]
Bitdeer Rockdale · Bitdeer
Rockdale · Milam County · online 2019
~170 MW operating (reported) · Bitcoin mining
Next door to Riot on the same former Alcoa land — the campus where Bitmain first broke ground in 2019, making Rockdale the town where industrial-scale Texas mining began. [4][5]
Riot Corsicana · Riot Platforms
Corsicana · Navarro County · online 2024
400 MW mining · 1 GW approved · Mining + AI/HPC pivot underway
Riot's second Texas gigasite, with a full gigawatt approved by ERCOT. 400 MW mines Bitcoin today; in 2025 Riot halted further mining expansion to evaluate AI/HPC uses for the remaining 600 MW, and by August 2026 the entire campus was reported under a non-binding letter of intent to a single AI tenant. [2][26]
MARA Granbury · MARA Holdings
Granbury · Hood County · online 2022
~300 MW behind-the-meter · Bitcoin mining
Runs behind-the-meter at the 1,115 MW Wolf Hollow gas plant. MARA bought it in January 2024 in a $178.6 million two-site deal — and its cooling-fan noise made Granbury the center of the state's hardest local fight over mining. [6][7][8][18]
Core Scientific Denton · Core Scientific / CoreWeave
Denton · Denton County · online 2022
~260 MW critical IT (AI conversion) · AI/HPC data center
A city-partnered Bitcoin campus that became the template for the AI pivot: a $6.1 billion conversion to high-performance computing for CoreWeave, which then agreed to acquire Core Scientific outright. [13][14]
Cipher Odessa · Cipher Mining
Odessa · Ector County · online 2022
207 MW · Bitcoin mining
Cipher's Permian Basin workhorse — 207 MW in the middle of oil-and-gas country, where drilling rigs and hashboards share the same skyline. [9]
Cipher Black Pearl · Cipher Mining
Wink · Winkler County · online 2025
300 MW · Mining + AI/HPC pivot underway
Came online mining Bitcoin in 2025 and almost immediately became something bigger: the site is now leased to Amazon for AI infrastructure, with mining winding down as GPUs move in. [10]
Galaxy Helios · Galaxy Digital
Dickens County · online 2022
800 MW approved · 133 MW live for AI · AI/HPC data center
Built as Argo's flagship mine, bought by Galaxy for $65 million in December 2022 out of Argo's distress, and reborn as an AI campus: on July 6, 2026 Galaxy delivered its first 133 MW to CoreWeave under a 15-year, 526 MW lease. [11]
Hut 8 King Mountain · Hut 8
McCamey · Upton County · online 2022
280 MW · Bitcoin mining
280 MW co-located with the King Mountain wind farm on a West Texas mesa — proof of the Texas thesis that miners are buyers of last resort for renewable power in the middle of nowhere. [12]
Layer1 (historic) · Layer1 Technologies
Ward County · online 2020
100 MW substation (2020) · Historic site
The Peter Thiel-backed pioneer. In February 2020 — before Riot, before the China ban — Layer1 was mining in liquid-cooled containers off its own 100 MW West Texas substation and selling power back to the grid when prices spiked. The playbook everyone else later ran. [15][16]
Hut 8 Beacon Point · Hut 8
Nueces County · online 2026
1 GW campus · 704 MW leased · AI/HPC data center
Not a converted mine but Hut 8's purpose-built answer to the AI turn. The 1 GW campus is fully contracted across two 15-year, 352 MW leases — base-term value $19.6 billion — to a single high-grade tenant reported to be Nvidia, built to Nvidia's DSX reference design on interconnection secured with AEP Texas. The clearest sign that a Texas grid connection is now the prize. [21]
Cipher Barber Lake · Cipher Mining
Colorado City · Mitchell County · online 2026
300 MW · leased to Fluidstack · AI/HPC data center
Cipher built Barber Lake straight for AI. The entire 300 MW site is leased to Fluidstack under a roughly $3 billion, ten-year deal that Google agreed to backstop, with power slated to start flowing in October 2026. It never mined a block — the West Texas mining playbook, applied to GPUs. [23]
MARA Matagorda · MARA Holdings
Matagorda County · online 2027
up to 2 GW · phased 2027–28 · Announced / in development
MARA's coastal megasite-in-waiting. In July 2026 it signed to acquire a 1,200-acre Matagorda County site from HIF carrying up to 2 GW of power, paid in milestones — land, permits, and grid authorization among them — for a campus blending high-performance computing with flexible Bitcoin mining. Initial power is targeted for late 2027, making it exactly the kind of speculative gigawatt the August 2026 queue audit exists to test. [22]
Frequently asked questions
What is the largest Bitcoin mine in Texas?
Riot's Rockdale facility in Milam County is the largest Bitcoin mine in Texas, with 700 MW of developed capacity — the largest single Bitcoin mining facility in North America. It was built by Whinstone on the site of Alcoa's former aluminum smelter and acquired by Riot in May 2021 for roughly $651 million.
Where are Bitcoin mines located in Texas?
Texas Bitcoin mines cluster in two zones: central Texas industrial towns like Rockdale (Riot, Bitdeer), Corsicana (Riot), Granbury (MARA), and Denton (Core Scientific), and the wind- and gas-rich west — Odessa and Wink (Cipher), McCamey (Hut 8), and Dickens County (Galaxy Helios).
Why are Texas Bitcoin mines becoming AI data centers?
Because miners already hold what AI needs most: hundreds of megawatts of grid-approved power. Galaxy's Helios campus signed a 15-year CoreWeave lease and delivered its first 133 MW in July 2026, Core Scientific is converting Denton in a $6.1 billion buildout, and Cipher leased its new Black Pearl site to Amazon.
Why is so much Bitcoin mining in West Texas?
West Texas has abundant wind and solar generation, cheap land, and transmission that often carries more power than local demand can absorb. Miners act as flexible buyers of that stranded energy — Hut 8's 280 MW King Mountain site sits directly beside a wind farm — and power down when the grid needs the electrons back.
Do Bitcoin mines strain the Texas grid?
Large miners enroll with ERCOT as interruptible load and are paid to shut off during scarcity. In August 2023, Riot earned $31.7 million in power credits for curtailing during the heat wave. The real local friction has been noise, not power: MARA's Granbury mine faces nuisance lawsuits from neighbors over its cooling fans.
What is the Texas data-center queue freeze?
On August 4, 2026, Governor Abbott directed the Public Utility Commission and ERCOT to audit every data-center project in the state's interconnection queue, and ERCOT paused its 'Batch Zero' classification of large new loads. Data-center requests had reached roughly 90% of a 474 GW queue. The practical effect is to make already-approved power — including the Bitcoin miners' — more valuable.
