Phoenix Industrial Real Estate: TSMC & Amkor Corridor
If you’re still treating Phoenix as “just a TSMC story,” you’re missing the forest for the trees. The real magic is happening over in Peoria, where Amkor Technology is pushing dirt on a massive $7 billion advanced packaging campus. For the first time, we aren’t just making raw components and shipping them overseas to get finished. TSMC bakes the wafers in North Phoenix, sends them down the road, and Amkor wraps up the final product. That is a fully closed-loop domestic supply chain right in our backyard. For Phoenix industrial real estate, this is a completely different animal than a standalone mega-project.
It creates a massive localized gravity well, reshaping exactly where suppliers, high-tech manufacturers, and logistics guys are hunting for space. If you’re trying to lease, build, or buy industrial property in Phoenix in 2026, the TSMC-Amkor corridor is your new North Star. Plain and simple.
To fully understand the long-term trajectory of this real estate corridor, one must sort through speculations and analyze the underlying market data. This article breaks down the hard data, outlines the key submarkets to watch, and discusses how this mega supply chain shift could impact your upcoming industrial real estate transactions.
What the Phoenix Industrial Real Estate Data Reveals
Arizona’s economic development community has taken to calling semiconductors the state’s “sixth C” — alongside copper, cattle, cotton, citrus, and climate. That framing is earning its weight.
Per the Arizona Commerce Authority, Arizona has attracted more than 60 semiconductor-related expansions since 2020. Combined, those projects account for roughly 25,000 projected jobs and approximately $205 billion in committed capital investment — a figure no other state has matched. TSMC’s Arizona workforce passed 3,000 employees in 2025, and the company’s total capital commitment of $165 billion represents the single largest foreign direct investment in U.S. history.

Amkor broke ground in Peoria in October 2025. The original commitment was notable on its own. Then the company expanded its initial investment from over $1 billion to $7 billion across two phases, with more than 750,000 square feet planned at buildout. When complete, it will be North America’s largest outsourced semiconductor packaging and test facility.
None of this is speculative. The vacancy and absorption numbers in Deer Valley have been telling this story for months. Spec industrial space is functionally nonexistent in that submarket while active tenant requirements continue to outpace what’s available.

Industrial Real Estate Submarkets to Watch in Phoenix
Pricing, available land, and lease terms are not uniform across the Valley. Here is where things stand, submarket by submarket, based on our daily tracking.
North Phoenix / Deer Valley. This is where TSMC’s campus sits, and it remains the tightest industrial submarket in the metro. Available product is scarce. Tenant competition for the remaining supply is active. Shovel-ready parcels with confirmed utility access are the exception, not the rule.
Peoria / Peoria Innovation Core. Amkor’s campus is anchored near Loop 303 and Lake Pleasant Parkway. The City of Peoria has acquired roughly 834 acres of surrounding state trust land, one of the most substantial land positions in the Valley tied directly to chip-sector expansion. Near-term options exist here, but the window is moving. As Amkor’s build progresses toward completion in 2028, supplier and logistics tenants are expected to absorb the remaining inventory quickly.
West Valley (Goodyear, Buckeye, Avondale). Large-format distribution and logistics space continues to be absorbed throughout the West Valley. Much of that demand originates from manufacturing and chip-sector operators extending their footprint outward from the core production campuses.
Mesa Gateway / East Valley. Aerospace-adjacent manufacturing has been the traditional driver here. Increasingly, tenants with direct or indirect exposure to the chip supply chain are appearing in this corridor, too.
Chandler. Intel has maintained an advanced manufacturing presence in Chandler for decades, and the network of suppliers and manufacturers surrounding that campus has remained active.
Tempe. Primarily an industrial and R&D corridor. Amkor’s corporate headquarters is located here, and the submarket continues to attract tech-adjacent occupiers.
Phoenix Industrial Real Estate FAQs
Logistics infrastructure, a diversified labor base, and the largest concentration of new semiconductor capital commitment in the country are all converging here at the same time. TSMC’s fab and Amkor’s new packaging and test facility are generating sustained demand for supplier space, manufacturing campuses, and distribution facilities across multiple submarkets simultaneously. Vacancy in the surrounding areas is at some of the lowest levels the metro has recorded.
Both TSMC and Amkor are developing local technician and engineering talent through their own workforce programs. That is not a short-term construction story. A growing local technical workforce creates the conditions for sustained occupancy in supplier and manufacturing space near both campuses — the kind of demand that holds up through economic cycles.
North Phoenix and Deer Valley, where TSMC operates, have the tightest current conditions. Peoria’s Innovation Core is the next major focal point as Amkor’s project moves forward. The West Valley logistics corridor continues absorbing demand from companies extending their reach across the metro.
In Deer Valley, it is genuinely scarce. Power-ready, shovel-ready parcels with proximity to the TSMC campus are gone or under contract in most cases. Peoria has more runway — the 834-acre state trust land position provides near-term options that Deer Valley simply cannot offer at this stage. That said, pricing and availability will tighten as Amkor’s construction advances and suppliers commit.
Call Rowe and Associates to Make Your Power Move
$165 billion from TSMC. $7 billion from Amkor. Vacancy in the corridors that matter compressed to levels the Phoenix market hasn’t seen in years.
This market has moved well past general logistics. The competition is now for specialized space, confirmed utility access, and proximity to a supply chain that is being built out in real time. The clients who are positioned well over the next three years are acting on that reality now, not when the next wave of supplier tenants has absorbed what’s left.
