September 2026 Outlook: The Market Looks Fine Until You Strip Out Data Centers

Warren Z. Business Coaching

The headline number says construction backlog is at 8.5 months, up from July. Sounds healthy. Then you look closer: contractors with data-center work are sitting on 9.9 months of backlog. Everyone else is at 8.3. One in six contractors now holds a data-center contract — the highest share ever recorded.

If you’re a $2–10M GC without a data-center foothold, you’re bidding in a tougher market than the average suggests. Here’s what else the September numbers say:

Input prices keep climbing. Up 1.2% in August alone, up 8.9% versus last year. Steel mill products are up 23%, aluminum 27%, copper and brass 21%. On fixed-price work with no escalation language, that’s your margin walking out the door.

Tariffs are a contract problem now. The effective tariff rate on construction imports is nearly 28% — steel and aluminum at 50%, copper at 50%, lumber derivatives at 25%. Seventy percent of contractors say tariffs hit them this year; 40% raised their bid prices. The firms bleeding worst are the ones eating the cost on lump-sum jobs.

Labor is tight again. Job openings are near a two-year high and the industry needs hundreds of thousands more workers. Four out of five firms can’t find qualified craft workers. Thin crews mean sub defaults, safety incidents, and schedule slip — the stuff that turns a good job into a bad quarter.

Owners are hesitating. Six in ten contractors had an owner postpone, scale back, or cancel a project in the last six months, mostly over funding uncertainty. Planning activity is up, but so is abandonment. Winning the bid matters less than winning the right bid — and protecting your margin on it.

None of this means the market is dead. It means the easy money is gone, and the firms that win from here are the ones who know exactly where their pipeline and their margins are exposed.

That’s what the 90-day X-Ray is built to find. Book a Clarity Call and we’ll look at yours.
