Top Story: Austin's City Council voted Thursday to direct staff to start drafting a citywide ban on hyperscale (100MW+) AI data centers, the most aggressive municipal move yet against the industry in a major Texas city.

📰 Today's News

1. ⛔ Austin Votes to Begin Banning Hyperscale Data Centers Citywide

The Austin City Council voted today to direct City Manager T.C. Broadnax to begin drafting Land Development Code amendments that would ban data centers larger than 100MW anywhere in the city, a process the Austin Chronicle reports could take until spring 2027 to finish.
Mayor Kirk Watson and council members Fuentes, Alter, Velásquez, Qadri and Siegel back a full hyperscale ban; CM Krista Laine wants the line drawn lower, to also cover "large wholesale" centers in the 20-100MW range, while CM Duchen raised concerns about where exactly to draw any size cutoff.
Austin Energy's Stuart Reilly told council the utility currently serves roughly 10 data centers, all under 20MW — meaning the ordinance is aimed squarely at stopping future hyperscale projects rather than unwinding anything already built.
The vote lands the same day Axios Austin reported Anthropic is in talks for a 2,842-acre Bastrop County campus paired with its own 710MW gas plant, and one day after San Antonio's City Council began weighing its own — so far less sweeping — zoning restrictions, per the San Antonio Express-News.

Today's Signal: Fort Worth's council softened a project's footprint last week and Hinojosa is campaigning on a moratorium; Austin just became the first major Texas city to formally start banning hyperscale data centers outright, which raises the stakes on whether Fort Worth, San Antonio or others follow with bans of their own rather than conditions.

2. 🏗️ Central Texas's Data-Center Land Rush Keeps Compounding: New Filings, New Fights

Data Center Dynamics reports EdgeConneX has filed applications for four more buildings in Bastrop County's Cedar Creek submarket — two 577,000-square-foot buildings (a combined $1.4 billion) and two 730,000-square-foot buildings (another $1.4 billion) — on top of two buildings already filed in June, pushing its Cedar Creek footprint toward 12-plus buildings across 1,500-plus acres, with capacity partly leased to CoreWeave.
Separately, Axios Austin reports Anthropic has signed a $9.1 billion lease for a Rockdale campus on the former Alcoa smelter site and is leasing near Waco alongside its own 1.6-gigawatt gas plant, in addition to the Bastrop County project noted above; resident group Lost Pines Watch is now pushing TCEQ to scrutinize the air permit for that project's 710MW plant.
In Williamson County, MySA reports the Halt Taylor Data Centers Coalition held an Aug. 25 press conference over "Project Mustang" — developer Big Watt Digital/PowerHouse Data Centers' proposed 665-acre, 1,050-1,400MW site powered by up to 112 gas reciprocating engines — backed by a 1,400-signature petition and a writ of mandamus the coalition filed in a Texas appeals court alleging Taylor's council skipped a required vote.
Taylor's council is scheduled to take up annexation for the project on Sept. 10.

Today's Signal: Three unrelated filings in one submarket on one day — from a hyperscaler, a colo builder and a gas-fired independent — is what "land rush" looks like in practice, and it's happening in the same news cycle Austin just voted to keep more of it out of city limits.

3. ⚖️ Westlake's Data-Center Restraining Order Survives Its First Court Test

A Tarrant County judge heard arguments Wednesday on whether to lift the temporary restraining order blocking further work on Westlake's 1.1-million-square-foot, four-building PowerHouse data center campus, and instead extended the TRO through Sept. 8 without ruling on the underlying request for an injunction, per WFAA and CBS News Texas.
Plaintiffs — the Lakes at Marshall Ridge HOA and homeowners including Linda Bjorn — argue the town's December 2024 zoning text amendment, which nearly doubled the maximum building height from 45 to 80 feet, never mentioned "data center" in its public notice and that the site plan omits a mandated 150-foot landscaped buffer; their attorney Jason Friedman called the notice "deficient."
Westlake and developer Hillwood counter that a November 2024 public notice and the site's 1998 commercial/industrial zoning designation cover the project; the Fort Worth Star-Telegram notes P&Z approved the site plan Aug. 4 over more than 100 Keller objectors, and that Gov. Abbott's office said Aug. 18 — one day after the TRO was issued — that PowerHouse had agreed to comply with the state's grid-audit requirements.
The judge did not indicate when a ruling on the injunction itself will come, though both outlets reported it's expected within the next week.

Today's Signal: This is the same "deficient notice" argument now working in landowners' favor against Oncor's 765-kV lines — a sign the notice-and-process fights driving this week's grid news are just as live at the city-zoning level as they are before ERCOT and PUCT.

4. 📉 IREN's Childress Site Hits a Revenue Milestone — Right as the Stock Slides Into Earnings

IREN reports fiscal 2026 results today after market close, with the stock having closed down 5.6% on the session and roughly 7% for the week, about half off its 52-week high.
The company's Childress, Texas site delivered Microsoft its first live AI workload on Aug. 13 — the initial 50MW "Horizon 1" phase of a five-year, roughly $9.7 billion contract — marking IREN's first billable revenue from the deal; Nvidia designated the site an "Exemplar Cloud" deployment for its GB300-NVL72 systems.
IREN raised its 2026 AI-cloud annualized revenue target to more than $4 billion, citing roughly $2.8 billion in new multi-year contracts signed since the Childress milestone.

Today's Signal: A live Microsoft workload and a raised revenue target would normally read as good news, but the market's marking IREN down into earnings anyway — a reminder that Texas's neocloud builders are being judged on execution and margins now, not just on signed megawatts.

5. 🛢️ A Permian Energy Company Eyes a 1-5 Gigawatt Bet on Powering AI From the Ground Up

Conroe-based Olenox Industries (Nasdaq: OLOX) disclosed in a shareholder letter that it's pursuing a non-binding letter of intent to acquire Wildboy Holdings/IPD Industries, whose project interests near the Waha Hub outside Pecos sellers describe as capable of supporting 1 to 5 gigawatts of behind-the-meter generation long-term, plus nearby substations, gas midstream access and ERCOT market-participation authority.
The company frames the deal as expanding an "energy-to-compute" platform that already includes a bitcoin-mining unit (CS Digital Ventures, acquired May 2026) mining roughly 17 BTC a month; Olenox reported Q2 2026 revenue of about $2.1 million, up 194% year over year, and total assets of about $64.2 million, up 78% year-to-date.
Nothing is signed yet — the LOI is non-binding — but it's a specific, sourced example of the "power-first" strategy this briefing tracks: building the generation and grid access first, with AI or crypto compute as the buyer.

Today's Signal: A company this size chasing gigawatt-scale behind-the-meter generation in the Permian shows how far the "build power, then sell compute" playbook has spread beyond the hyperscalers and the big neoclouds already running it in the Panhandle and Permian Basin.

6. 📋 Prosper's Data Center Fight Gets Its Court Date, Sort Of

Prosper's Planning & Zoning Commission will finally take up "Project Tomahawk" on Sept. 1, after the item was pulled from the Aug. 18 agenda — a 225,000-square-foot data center on 37.3 acres at FM 1385 and Parvin Road, filed by developer White Rose Partners, per Community Impact.
The request seeks to rezone agricultural land to a planned development; the site sits next to a Brazos Electric Power Cooperative substation, with the developer on the hook for upgrade costs, and the applicant is proposing a closed-loop water design using roughly half the water of a typical single-family home per year.
Written opposition outnumbers support 34 comments to 1, including 11 from Prosper residents themselves, though no homes sit within 200 feet of the site.

Today's Signal: A 34-to-1 opposition margin before the hearing even happens shows the same organized pushback seen in Westlake and Taylor is now standard practice for any DFW-area data-center rezoning, not the exception.

Quiet today on ERCOT's own interconnection-queue and large-load readiness-test postings, and on new TCEQ air-permit filings in the eight DFW-ring counties this briefing tracks most closely — today's environmental and land-use news instead came out of Central Texas.

📍 Today's Watch List

Actionable Signals for Thursday, August 27

Whether Austin's draft ordinance, expected to take shape over the coming months, ends up covering only 100MW-plus hyperscale sites or also the 20-100MW "large wholesale" tier CM Laine is pushing for.
Whether San Antonio's council follows Austin toward an outright ban rather than the lighter zoning restrictions it's currently weighing.
Whether the Tarrant County judge rules on Westlake's injunction before the TRO lapses Sept. 8, and whether the "deficient notice" argument succeeds there the way it's already swaying ALJ panels against Oncor's 765-kV lines.
Whether Taylor's Sept. 10 annexation vote or the pending writ of mandamus slows "Project Mustang" before its gas-engine buildout advances further.
Whether Prosper's Sept. 1 P&Z hearing on Project Tomahawk reflects the same lopsided opposition seen in written comments so far.
Whether PUCT's Aug. 28 vote on the three STEP Permian 765-kV segments acts on the ALJ recommendations to deny two of them — a buildout Texas Scorecard reports could add roughly $100 billion in ratepayer costs over its life.
Whether IREN's Thursday earnings call explains the stock's slide despite the Childress revenue milestone, and whether the roughly 7% weekly decline continues.
