Every AI Data Center Under Construction in the US, Mapped (2026)

xAI's Colossus 1 in Memphis, switched on in 2024, has more than 300 megawatts of capacity and is now rented in full to Anthropic. In November 2026, Meta is building a campus in rural Louisiana planned for 5 gigawatts, OpenAI and its partners have seven Stargate sites under way in five states plus two larger campuses announced in Ohio and Georgia, and bitcoin miners in Texas, New York and Louisiana are leasing hundreds of megawatts to Microsoft, CoreWeave and Anthropic's cloud partner Fluidstack. This is the master map of that buildout: every major US AI data center project we could verify that is running, under construction, approved or announced with a confirmed site, grouped by builder or buyer.

The headline numbers, as of November 15, 2026: our table lists 57 projects in 24 states. Fifteen are already running at least in part, 26 are under construction, four hold local approvals and 12 are announced with a named site. The capacity figures that developers, tenants and utilities have published for 30 of them add up to roughly 40 GW, and the investment figures published for 25 of them add up to about $394 billion. Both are sums of announced numbers, mixing IT load and grid power the way each source states them, so treat them as floors. Texas leads with 15 projects, followed by Indiana and Ohio (4 each), then Georgia, Louisiana, Mississippi and Pennsylvania (3 each).

Why AI data centers are being built at this scale

Training a frontier model means keeping hundreds of thousands of GPUs or TPUs busy in one place, and the same campuses increasingly serve those models to users: Anthropic rented all of Colossus 1 to raise usage limits for paying Claude subscribers. Meta says the first phase of Prometheus, its "gigawatt-scale supercluster" in Ohio, is complete and that it is working toward about 1 million GPUs. At that size the limit is electricity, which is why the map is full of places with spare grid capacity or room for a power plant: the Texas Panhandle, northeast Louisiana, North Dakota, rural Michigan.

Developers now pair campuses with their own generation (900 MW on site at Crusoe's new Abilene halls, a gas-fed fuel-cell plant proposed for Project Jupiter in New Mexico, turbines in Southaven feeding xAI's Colossus 2, a 7.65 GW gas plant permitted in Pecos County, Texas, for an Amazon campus), with nuclear contracts (Talen's Susquehanna plant selling up to 1,920 MW to AWS through 2042) or with utility special contracts (DTE in Michigan, Entergy in Louisiana and Arkansas). Financing changed too: Meta moved Hyperion into a joint venture with Blue Owl, and Google backstops the leases that let Fluidstack rent capacity from crypto miners for Anthropic.

The master map: every major US AI data center project

Projects qualify at roughly 300 MW or $1 billion announced, or as a nationally covered AI training or inference campus. Capacity is in the unit the source uses. "Epoch est." marks a satellite-based estimate from Epoch AI's Frontier Data Centers Hub, used where the company publishes no figure. Investment is the announced figure; leases, bonds and contracts are labelled as such.

Adding up the gigawatts and dollars

Companies disclose capacity and spending inconsistently, and Microsoft, Amazon and Google rarely publish megawatts at all. Totalling only what was announced:

• Investment: about $394 billion across 25 projects, led by Hyperion ($50 billion+), Google's $40 billion Texas plan (three campuses, counted once), Lambda's proposed $33.1 billion in Alabama, Vantage's $25 billion Frontier campus and AWS's $21 billion in Madison County, Mississippi.
• Capacity: roughly 40 GW across 30 projects with a stated figure. PORTS-Pike alone is 8 GW of IT capacity and Hyperion 5 GW, and 16 projects claim 1 GW or more.
• Running today: about 5.9 GW of IT load, using Epoch AI's satellite estimates for 13 operating sites plus Applied Digital's own figure for Ellendale. Project Rainier, Colossus 2 and Stargate Abilene account for nearly half.

The dollar total leaves out Project Jupiter's $165 billion bond authorization (a financing ceiling), financing, lease and contract values (Abilene's reported $15 billion of project financing, IREN's $9.7 billion with Microsoft, Anthropic's $19 billion Hawesville lease, Hut 8's roughly $7 billion with Fluidstack), Homer City's $10 billion energy campus figure, set before AWS filed its plans, and statewide plans that include sites outside our table (AWS's $20 billion in Pennsylvania, Google's $9 billion in Oklahoma). The capacity total leaves out power plants: GW Ranch (7.65 GW), Homer City (up to 4.4 GW), Fermi's 6 GW of permits and Google's 702 MW fuel-cell plant in Wyoming.

How many AI data centers are being built in the US?

It depends on who is counting and what counts as "under construction." The three main trackers in the second half of 2026:

• Wood Mackenzie (October 28, 2026): projects totalling nearly 80 GW under construction in the US, up from 44 GW at the end of Q1, inside a disclosed pipeline of more than 430 GW.
• JLL (August 11, 2026): 66 GW under construction across North America, 95% of it pre-committed.
• CBRE (August 27, 2026): a record 7,481 MW under construction in North America's primary colocation markets, a narrower measure that leaves out most of the rural self-built campuses in this post.

All three cover data center capacity of every kind; none of the releases gives an AI-only figure. Our own count is narrower still: 57 named AI projects, 41 of them running in part or under construction.

Where are AI data centers being built? State by state

Texas leads on land, gas, wind and a grid operator, ERCOT, where Wood Mackenzie says more than 40% of the capacity in development is already under construction. JLL counts 26 GW of existing and under-construction capacity in Texas against 13 GW in Virginia. Georgia has three projects in our table, and CBRE ranks metro Atlanta first in North America for capacity under construction (2,882 MW), ahead of Northern Virginia. Projects like these usually need a rezoning, a utility contract and an air permit; our record of every major US data center approval covers that side state by state.

The largest AI data centers in the US

Ranked by the capacity the developer, tenant or utility has announced:

Power plants built for data centers are left out of the ranking: Fermi America's Project Matador near Amarillo holds air permits for 6 GW of generation but has no tenant, GW Ranch in Pecos County is permitted for 7.65 GW of gas turbines to power a planned Amazon campus, and Homer City in Pennsylvania has an air permit for up to 4.4 GW. By IT load now running, Epoch AI's estimates put AWS's Project Rainier first at about 1,037 MW, ahead of Colossus 2 (946 MW), Stargate Abilene (824 MW) and Fairwater Atlanta (636 MW). Epoch also projects Fairwater Wisconsin at about 2.3 GW of IT by 2028 and Project Jupiter at 2.2 GW.

Timeline: how the map filled in, 2025 to November 2026

• 2025: Five more Stargate sites are named in September, the month Crusoe declares Abilene's first phase live. Fairwater Atlanta and Project Rainier come online in October. Anthropic commits $50 billion with Fluidstack and Google announces $40 billion for Texas in November.
• Q1 2026: SpaceX completes its merger with xAI (February 2), Meta breaks ground in Lebanon, Indiana (February 11) and lifts El Paso from $1.5 billion to $10 billion (March 26). Oracle and OpenAI drop the Abilene expansion (reported March 6) and Microsoft takes the 900 MW (March 27).
• Q2 2026: Coweta County, Georgia rezones Project Sail (April 7) and AWS raises its Mississippi plan to $25 billion (April 9). Anthropic takes all of Colossus 1 (May 6). Google commits $15 billion in Missouri (May 20), and Microsoft announces about 2 GW in Pecos, Texas (June 22), a day before declaring its first Fairwater Wisconsin building fully operational.
• Q3 2026: Anthropic signs a $19 billion lease in Hawesville, Kentucky (July 6) and Meta lifts Hyperion to 5 GW and $50 billion+ (July 13). OpenAI's Project Camellia (July 22) and PORTS-Pike (August 17) are announced, and Amazon confirms its backing for the GW Ranch gas plant (August 7) and an $18 billion Louisiana plan (August 18). New Mexico's Supreme Court pauses Project Jupiter's air permit case (August 23), then lets it proceed in September, the month Oracle reports six of eight Abilene buildings delivered.
• Q4 2026 to date: Microsoft trims one Mount Pleasant parcel and Meta completes Prometheus's first phase (October). Lambda proposes $33.1 billion in Alabama, Google announces $17 billion in Wyoming and AWS breaks ground in Wheatfield, Indiana (November).

Builder by builder (the short version)

OpenAI, Stargate and Oracle

Seven US Stargate sites, all but Abilene still under construction, plus two larger campuses OpenAI announced in 2026 without the Stargate name: PORTS-Pike in Ohio (8 GW of IT capacity, built and owned by SB Energy with Nvidia credit support) and Project Camellia in Georgia (3.2 GW), which OpenAI is developing itself. Oracle owns the hardware at five Stargate sites under its 4.5 GW agreement with OpenAI; SoftBank owns Milam County and Lordstown. We found no Oracle-led US AI campus outside Stargate that met our bar, so Oracle's sites sit in this group. Epoch AI's April review projects most Stargate sites finishing in late 2028. Our Stargate data center map covers each site, partner and financing deal.

Meta

Meta has the largest project under construction, Hyperion, and four campuses of a gigawatt or more: Prometheus is running, while El Paso and Lebanon, Indiana target 1 GW each. Our Big Tech AI data centers post covers Meta, Microsoft, Amazon, Google, xAI and Anthropic campus by campus.

Microsoft

Microsoft runs two Fairwater "AI superfactories" in Wisconsin and Georgia, where the capacity figures are Epoch AI estimates, and rents capacity from Crusoe (Abilene), IREN (Childress) and Nebius (Vineland). Its next large campus of its own is in Pecos, Texas: about 2 GW, starting on a co-located gas plant off the public grid.

Amazon (AWS)

Project Rainier, where Anthropic trains its models, is the largest running AI campus by Epoch's estimate, and WNDU reports AWS has spent $13.8 billion there so far. AWS has 11 projects in our table, spread over eight states. Two of the newest depend on private gas plants: Amazon confirmed in August that it is backing GW Ranch, a plant permitted for 7.65 GW in Pecos County, Texas, and AWS has filed plans for 36 buildings at Pennsylvania's Homer City campus, Baxtel reported.

Google

Google has nine campuses in our table (Haskell County has two), several built by partners such as Crusoe in Armstrong County and Panattoni near Detroit. A day after Google announced $17 billion in Wyoming, Crusoe said Google had acquired the southeast Wyoming campus it had prepared with Tallgrass.

xAI (now part of SpaceX)

Colossus 2 is the second-largest running AI site in the US by Epoch's estimate, powered partly by turbines across the state line in Southaven, Mississippi. The $20 billion MACROHARDRR building in Southaven was due to start in February 2026; we found no confirmation that it has.

Anthropic

Anthropic builds through partners: AWS (Project Rainier), SpaceX (Colossus 1 and part of Colossus 2) and Fluidstack, which leases from bitcoin miners turned landlords (TeraWulf, Cipher, Hut 8) with Google backstopping the leases. Hut 8 says its partnership could reach about 2.3 GW. In July 2026 Anthropic also signed a $19 billion, 20-year lease directly with TeraWulf for a 401 MW campus in Hawesville, Kentucky.

Neoclouds and independent developers

CoreWeave anchors much of this group (Denton, Helios, Ellendale, Lancaster). Applied Digital has 250 MW running at Ellendale and more leases with an unnamed hyperscaler at undisclosed sites. IREN, Fermi America, QTS and the developers of Project Sail in Georgia (Prologis) and Project Blue in Arizona (Beale Infrastructure) have no tenant announced, and Lambda's proposed Alabama campus is the largest dollar figure from a neocloud.

The 2026 pattern: power first, tenant second, and plenty of churn

Bitcoin miners with grid connections became AI landlords in under two years: Core Scientific (Denton), Galaxy (Helios), TeraWulf (Lake Mariner), Cipher (Barber Lake), Hut 8 (River Bend) and IREN (Childress and Sweetwater). Developers without that head start build their own plants, from Fermi's turbines in the Panhandle to the 41 gas turbines Mississippi permitted for xAI in March 2026 and the 7.65 GW GW Ranch plant behind Amazon's Pecos County campus.

Signed sites also changed shape during 2026:

• Re-leased: Oracle and OpenAI walked away from the Abilene expansion in March (The Register); Meta was in talks for it, and Microsoft signed.
• Resized: Hyperion went from 2 GW to 5 GW, and Microsoft cut two buildings from one Mount Pleasant parcel.
• Lost a tenant: CoreWeave and Poolside parted ways on Poolside's planned 2 GW Horizon campus in West Texas (Baxtel, April 2026), so it is not in our table.
• Contested: the New Mexico Supreme Court paused Project Jupiter's air permit case and water well in August, then let both go ahead in September, with a public hearing on the revised permit set for December 7. Michigan's attorney general is appealing the Saline power contracts, and residents fought AWS's air permits in Richmond County, North Carolina.
• Unconfirmed: MACROHARDRR's February start, and any Fermi tenant.

Projects that were stopped outright, and the local moratoriums behind them, are in our tracker of US data center moratoriums and blocked projects.

What this means for your AI visibility

Residents, county commissioners, reporters, investors and job seekers now research a data center by asking ChatGPT, Google AI Mode or Perplexity: "Is the data center in Saline Township approved?", "Who is building the data center in Hamlet?", "How much water will it use?" The answer, the sources it cites (the local paper, an opposition group's site, the developer's press release, a utility filing) and its tone shape opinion before anyone attends a hearing. The facts on this map change every few weeks, so a model can easily repeat a stale capacity figure or a departed tenant.

For developers, utilities, economic development agencies and the companies behind these campuses, that is a visibility and reputation question you can measure. LLM Pulse tracks brand mentions, the sources and URLs AI answers cite, share of voice and sentiment across ChatGPT, Perplexity, Gemini, Google AI Mode and Google AI Overviews, with daily, weekly or monthly tracking; Claude, Copilot, Grok, Meta AI and other models are paid add-ons. Tracking prompts like "who is building the data center in [county]" shows which sources the models trust and whether your account reaches the answer.

Summary

As of November 2026, the US has at least 57 major AI data center projects running, under construction, approved or announced with a site, across 24 states and led by Texas. Announced figures add up to roughly 40 GW and $394 billion, while industry trackers put data center capacity under construction anywhere from 7.5 GW in North America's main colocation markets (CBRE) to nearly 80 GW across the US (Wood Mackenzie). OpenAI's PORTS-Pike campus in Ohio is the largest announced, Meta's Hyperion the largest under construction and AWS's Project Rainier the largest running one by Epoch AI's estimate. The next dates to watch are New Mexico's December 7 hearing on Project Jupiter's air permit and the Louisiana Public Service Commission's December 10 vote on Entergy's seven new plants for Meta.
