Austin anchors the fastest-rising data center corridor in Texas, the Austin-San Antonio market that went from secondary to primary in about 18 months. Here’s the metro-level picture: the suburban submarkets driving growth, the semiconductor and AI demand behind it, and what the build-out means for the equipment that eventually retires.
TL;DR
Austin is the northern anchor of the Austin-San Antonio corridor, which topped the secondary-market rankings in 2026 and is now functioning as a primary market. (For the statewide picture, see our Texas Data Center Market 2026 Guide, and for the causal mechanics, Why Texas Became a Data Center Hub.)
The metro-level essentials:
- The Austin-San Antonio corridor rose from secondary to primary in roughly 18 months, topping Cushman & Wakefield’s 2026 secondary-market ranking.
- Combined Austin-San Antonio under-construction capacity quadrupled off its 2024 base, per CBRE, reaching several hundred megawatts under construction.
- Growth concentrates in the suburban tech corridor, with major activity in Round Rock, Hutto, Pflugerville, Taylor, and the I-35 belt rather than central Austin.
- The Tract Caldwell County campus between Austin and San Antonio approaches 3,000 acres with 2 GW of planned capacity, anchoring the corridor’s southern end.
- Distinct demand drivers set Austin apart: semiconductor-industry proximity (edge compute), AI model training, sovereign cloud, and hyperscaler migration from DFW and Houston.
The metro-specific angle for infrastructure operators: Austin’s growth is newer and faster than DFW’s, which means its retirement wave arrives slightly later but accelerates quickly, especially given the high concentration of liquid-cooled, AI-dense facilities being built here that run on the most compressed refresh cycles.
Why Austin Became a Data Center Corridor
Austin’s data center rise is distinct from DFW’s. Where Dallas built its market on decades of interconnection depth, Austin’s growth is newer, faster, and driven by a different mix of forces.
The Tech and Semiconductor Ecosystem
Austin is a major technology hub with a dense concentration of tech companies, semiconductor manufacturing (Samsung, NXP, and others in the broader region), and the talent ecosystem that comes with them. This proximity creates demand for low-latency edge compute and positions Austin for semiconductor-driven and automotive-edge workloads that benefit from being near the enterprises generating the data.
Land and Power Availability vs DFW
Central Texas land prices run below DFW averages, and ERCOT queue data has shown greater available interconnection capacity near Austin than in the more saturated DFW corridors. For operators, that combination (cheaper land, more accessible power) made the Austin-San Antonio corridor an attractive alternative as DFW’s power corridors filled.
The I-35 Transmission Spine
The corridor between Austin and San Antonio follows the I-35 transmission infrastructure, which provides the backbone for the campuses spreading along it. The corridor’s transmission access is part of why it could scale so quickly from secondary to primary.
Hyperscaler Migration
Part of Austin’s growth comes from hyperscaler expansion programs migrating capacity from DFW and Houston, seeking the contiguous parcels capable of supporting 100 MW incremental builds that the Austin corridor can still offer. The Texas-wide tax and regulatory advantages (covered in the Why Texas piece) apply here as everywhere in the state.
The Austin Submarkets
Austin’s data center geography looks different from DFW’s. The growth isn’t in the urban core, it’s in the suburban tech corridor ringing the city, especially to the north and east along and around I-35.
| Submarket | Profile |
|---|---|
| Round Rock | A burgeoning tech corridor and one of the most active submarkets. Sabey’s multi-building campus and Skybox developments anchor it, with liquid-cooling-ready facilities for AI and hyperscale. |
| Hutto | Site of large-scale development, including a 600 MW Skybox facility, reflecting the corridor’s shift toward hyperscale-scale campuses |
| Pflugerville | Active submarket with multiple developments in the 30 MW range and up |
| Taylor | Drawing data center development alongside the broader semiconductor investment in the area |
| Cedar Creek | EdgeConneX is delivering a 240 MW facility here, one of the larger single-site builds in the corridor |
| Hutto / Martindale / Caldwell County (southern corridor) | The Austin-San Antonio land bridge, anchored by the Tract Caldwell County 2 GW technology park approaching 3,000 acres, plus Edged’s large Martindale development |
The pattern: Austin’s data center build-out spreads along the suburban I-35 belt and increasingly down the corridor toward San Antonio, rather than concentrating in the city itself. This is partly land and power economics and partly the corridor’s emergence as a single integrated market.
Capacity and Growth
Austin’s growth trajectory is among the steepest in the country in percentage terms, reflecting its rapid rise from a smaller base.
The consistent findings across market research:
- The Austin market was valued around 1.5 GW in 2025, with steady forecast growth, per Mordor Intelligence.
- Combined Austin-San Antonio under-construction capacity quadrupled off its 2024 base, per CBRE, which ranked the corridor among the top secondary markets in the country.
- Dozens of facilities are operational or planned in the broader Temple-to-San Antonio corridor, with potential for that number to grow substantially as unconfirmed projects advance.
- Liquid-cooling adoption is notably high in the new Austin builds, reflecting the AI-density orientation of the corridor’s facilities (one Sabey Austin building reported the large majority of deployments as liquid-cooled).
One Texas-wide nuance applies sharply in Austin: the gap between committed and constructed capacity has widened. Commitments are stacking up faster than construction can advance, driven by longer, more complex build cycles and power-alignment challenges. The corridor can look oversupplied on paper (commitments) while feeling tight operationally (delivered capacity). Execution discipline, early utility alignment, and power strategy increasingly separate the projects that deliver from those that stall.
Who’s Building in Austin
The operator mix leans toward specialist developers and hyperscalers, with a notable AI and liquid-cooling orientation:
| Category | Operators Active in the Austin Corridor |
|---|---|
| Hyperscalers | Alphabet (Google) and Microsoft, both with multi-site expansion programs in the corridor |
| Specialist developers | Sabey Data Centers (Round Rock campus, liquid-cooling-ready), Skybox (Hutto 600 MW, Round Rock, Pflugerville), EdgeConneX (Cedar Creek 240 MW), Tract (Caldwell County 2 GW), Edged (Martindale), Sabey, Rowan Digital, Colovore (liquid-cooled “Project Raptor” in Hutto) |
| Edge and specialty | Operators targeting semiconductor-adjacent edge compute and automotive workloads |
The demand mix (AI training, sovereign cloud, semiconductor-edge, automotive) skews toward high-density, liquid-cooled deployments, which is why so many of the corridor’s new facilities are designed liquid-cooling-ready from the start.
The Power and Build-Cycle Dynamics
Austin’s power situation differs from DFW’s in a useful way, with its own emerging constraints.
More Available Interconnection (For Now)
Compared to the saturated DFW power corridors, the Austin-San Antonio corridor offered greater available ERCOT interconnection capacity, which was part of its appeal. That relative advantage is narrowing as the corridor fills, but it helped drive the rapid early growth.
Renewable Blending
The corridor’s position lets operators blend West Texas wind and solar into their power strategies through favorable ERCOT rules, supporting the renewable-procurement commitments many operators carry. Several corridor projects pair with electric cooperatives and renewable sourcing.
The Widening Build Gap
The corridor feels the statewide friction between commitments and delivery acutely. Longer build cycles, supply-chain complexity, and power-alignment timelines mean that the headline commitment numbers run well ahead of operational capacity. For the market, this means sustained construction activity for years as the committed pipeline works through the build process.
What the Austin Build-Out Means for Infrastructure Retirement
The Austin corridor’s retirement profile differs from DFW’s in timing and character.
Because Austin’s build-out is newer than DFW’s, its installed base is younger, so the retirement wave arrives slightly later. But two factors make that wave accelerate quickly once it starts:
- The facilities are AI-dense and liquid-cooled. The corridor is being built for high-density AI workloads, which run on the most compressed refresh cycles (18-36 months). The GPU-heavy, liquid-cooled facilities going up in Round Rock, Hutto, and the Caldwell corridor today will generate concentrated retirement volume on a faster cycle than traditional enterprise gear.
- The semiconductor and edge orientation adds specialty equipment. Austin’s edge-compute and semiconductor-adjacent workloads bring equipment categories beyond standard servers, which require informed asset recovery to capture value rather than defaulting to recycling.
The metro-specific implications mirror the broader Texas pattern, applied to the corridor’s character:
- Retirement is local and logistics-heavy. Equipment retired from Austin-corridor facilities needs de-racking, sanitization, and remarketing or recycling where it sits, along the I-35 belt and down toward San Antonio.
- AI re-tenanting drives speed. As corridor facilities refresh for next-generation AI, rapid decommissioning clears space for high-value redeployment faster.
- Recovery value favors local presence and speed. GPU systems and high-density networking retired from Austin facilities lose value with each hardware generation, making speed-to-remarketing a direct return issue.
The fastest-growing Texas corridor will become one of its fastest-growing retirement markets, on a slight lag but an accelerating curve.
Frequently Asked Questions
How big is the Austin data center market?
The Austin data center market was valued at roughly 1.5 GW in 2025 with steady forecast growth, per Mordor Intelligence. As part of the broader Austin-San Antonio corridor, it topped Cushman & Wakefield’s 2026 secondary-market ranking and is now functioning as a primary market. Combined Austin-San Antonio under-construction capacity quadrupled off its 2024 base per CBRE, making the corridor one of the fastest-growing data center markets in the country.
Why is Austin a growing data center hub?
Austin’s rise rests on a distinct mix: a dense tech and semiconductor ecosystem (Samsung, NXP, and others) driving edge-compute demand; central Texas land prices below DFW averages; greater available ERCOT interconnection capacity than the saturated DFW corridors; the I-35 transmission spine connecting Austin to San Antonio; and hyperscaler migration from DFW and Houston seeking contiguous parcels for large incremental builds. The Texas-wide tax and regulatory advantages apply on top of these corridor-specific drivers.
What are the main data center submarkets in Austin?
Austin’s data center growth concentrates in the suburban tech corridor rather than the urban core, especially along and around I-35 to the north and east. Key submarkets include Round Rock (Sabey and Skybox campuses), Hutto (a 600 MW Skybox facility and Colovore’s liquid-cooled Project Raptor), Pflugerville, Taylor, and Cedar Creek (EdgeConneX 240 MW). The southern end of the corridor toward San Antonio includes the Tract Caldwell County 2 GW campus and Edged’s Martindale development.
What companies have data centers in Austin?
Hyperscalers Alphabet (Google) and Microsoft both run multi-site expansion programs in the corridor. Specialist developers include Sabey Data Centers (Round Rock, liquid-cooling-ready), Skybox (multiple corridor facilities including a 600 MW Hutto site), EdgeConneX (Cedar Creek), Tract (Caldwell County 2 GW), Edged (Martindale), Rowan Digital, and Colovore. The demand mix skews toward AI training, sovereign cloud, and semiconductor-adjacent edge workloads.
What makes the Austin data center market different from Dallas?
Austin’s market is newer, faster-growing, and differently driven than DFW’s. Where Dallas built on decades of interconnection depth (the Infomart, the Richardson Telecom Corridor), Austin grew rapidly on tech and semiconductor proximity, cheaper land, more available power, and hyperscaler migration. Austin’s facilities skew more heavily toward AI-dense, liquid-cooled designs, and its growth concentrates in suburban submarkets along I-35 rather than an established urban core. DFW remains the larger, more mature anchor; Austin is the fast-rising corridor.
What is the Austin-San Antonio corridor?
The Austin-San Antonio corridor is the integrated data center market spanning the two cities along the I-35 transmission spine. It rose from secondary to primary market function in roughly 18 months, topping Cushman & Wakefield’s 2026 secondary-market ranking. The corridor includes Austin’s northern suburban submarkets (Round Rock, Hutto, Pflugerville), the land bridge between the cities (anchored by the Tract Caldwell County 2 GW campus), and San Antonio’s market to the south. The corridor’s rapid integration reflects shared transmission infrastructure and the spread of development along I-35.
How does the Austin data center boom affect equipment retirement?
Austin’s build-out is newer than DFW’s, so its retirement wave arrives slightly later, but it accelerates quickly because the corridor’s facilities are AI-dense and liquid-cooled, running on the most compressed refresh cycles (18-36 months). The GPU-heavy facilities being built in Round Rock, Hutto, and the Caldwell corridor today will generate concentrated retirement volume on a fast cycle. The semiconductor and edge orientation also brings specialty equipment categories that benefit from informed asset recovery. Because decommissioning is a physical operation, that retirement concentrates along the Austin I-35 corridor.
Why are Austin data centers built in the suburbs rather than the city?
Land and power economics. Central Austin land is expensive and power-constrained, while the suburban tech corridor (Round Rock, Hutto, Pflugerville, Taylor) and the I-35 land bridge toward San Antonio offer the larger parcels, more available power, and lower land costs that large data center campuses require. The suburban corridor also follows the I-35 transmission infrastructure, providing the grid backbone for the campuses spreading along it.
Why is liquid cooling common in Austin data centers?
Austin’s data center demand skews heavily toward AI training, high-performance computing, and semiconductor-adjacent edge workloads, all of which involve high-density compute that generates more heat than traditional servers. Liquid cooling handles that heat far more efficiently than air cooling at high rack densities, so many of the corridor’s new facilities are designed liquid-cooling-ready from the start. This AI-density orientation also means these facilities run on compressed hardware refresh cycles, which has downstream implications for equipment retirement timing.
The Bottom Line
Austin anchors the fastest-rising data center corridor in Texas, the Austin-San Antonio market that went from secondary to primary in about 18 months. Its growth is distinct from DFW’s: newer, faster, and driven by semiconductor and tech proximity, cheaper land, more available power, the I-35 transmission spine, and hyperscaler migration from the older Texas markets. The build-out concentrates in suburban submarkets (Round Rock, Hutto, Pflugerville, Taylor) and spreads down the corridor toward San Antonio, with a heavy orientation toward AI-dense, liquid-cooled facilities.
For infrastructure operators, the Austin corridor’s retirement profile arrives on a slight lag behind DFW’s but accelerates fast, because the corridor is being built for exactly the high-density AI workloads that refresh on the most compressed cycles. The fastest-growing Texas corridor will become one of its fastest-growing retirement markets. Operators planning disposition ahead of the refresh, with local presence and the speed to remarket before generational value decay, will capture more recovery value as the wave builds.
