JLL: big‑box leasing jumps 80.7%

Warehouse leasing is picking up again — and the clearest sign is the return of the giant deal. JLL’s first-quarter U.S. industrial report says big-box leasing, meaning spaces of at least 500,000 square feet, jumped 80.7% from a year earlier. That is a sharp reversal from the cautious mood that defined much of 2025, when many occupiers delayed large commitments. The point is not just that more leases got signed. It is that companies are willing to make long-duration bets on very large buildings again. (jll.com) ### What counts as a big box? In this case, JLL is talking about industrial spaces of 500,000 square feet or more. These are the huge distribution buildings used by retailers, third-party logistics firms, and large manufacturers — the kind of facilities built for regional fulfillment, automation, and dense truck traffic.

Total U.S. industrial leasing reached 145.2 million square feet in Q1 2026, up 17.8% from a year earlier. JLL also said 71.6% of leases were new commitments rather than renewals, which matt(jll.com)tanding still. (jll.com) ### Why are tenants taking giant buildings again? Part of it is a quality shift. Occupiers want newer buildings with better clear heights, more trailer parking, stronger power, and layouts that work with automation.

Logistics operators, retailers, and supply-chain users are reworking networks after a stretch of overexpansion, destocking, and uncertainty. The catch is that they are being choosier.

A rebound in leasing does not erase the supply wave that hit the market over the last two years. Cushman & Wakefield said Q1 was the strongest first quarter in three years, with 40 million square feet of net absorption, but it still described the market as(hbcapitalre.com)le, which tells you landlords still have to compete for tenants.

If a building is first-generation, near major freight corridors, and ready for immediate occupancy, the tenant pool is improving.

The rebound does not mean easy underwriting. Landlords may still need concessions. Some large users will tour multiple options before signing. And if a property misses on location, specifications, or timing, the vacancy risk can still bite hard. Basically, the market is rewarding the best big boxes again — not every big box. (jll.com) ### Bottom line The important part of JLL’s report is not just that leasing rose. It is that companies are once again committing to very large industrial footprints. That is a real demand signal. But it is a selective one — strong enough to help top-tier warehouse owners, not broad enough to rescue mediocre space.
