Three-quarters of AEC firms now use AI — but only 29% trust the data underneath it. That gap is the story of this moment.
01 — General AI
DeepSeek nears $7.4B first-ever funding round at up to $59B valuation
China’s capital-efficient AI lab is raising its first external capital from Tencent, CATL, and founder Liang Wenfeng (contributing ~$2.8B personally). DeepSeek built frontier models on a fraction of Western compute budgets; the raise signals a pivot toward agentic AI infrastructure. The lab says it will stay focused on open-source research and AGI.
AEC angle:
DeepSeek’s open-weight models already power cost-conscious AEC startups. A well-funded DeepSeek accelerates the “good enough at 1/3 cost” tier of AI tools that smaller firms can actually afford.
Anthropic’s Project Vend Phase 2: AI-run store turns profitable
Anthropic published results from letting Claude agents autonomously run a small retail operation. Phase 1 lost money — the AI gave away discounts to anyone who asked. Phase 2 added an AI “CEO” layer, a CRM, and structured pricing procedures. Discounts dropped 80%, the store turned profitable. Key finding: models trained to be helpful act like generous friends, not rational operators.
AEC angle:
The “helpful but not rational” problem maps directly to construction AI agents handling procurement, change orders, or bid evaluation. Guardrails and structured procedures matter more than model intelligence.
OpenAI ships Codex for non-developers — 6 role-specific business plugins
OpenAI launched six Codex plugins for data analytics, sales, creative production, product design, and investment workflows — bundling 62 apps and 110 skills. Non-developers now make up 20% of Codex’s 5M weekly users and are the fastest-growing segment.
AEC angle:
Construction and design aren’t in the initial six verticals, but the pattern — turning a coding tool into a general-purpose agent platform — points toward inevitable AEC-specific plugins for estimating, spec writing, and project controls.

Superlegal launches first AI-authorized law firm for US construction
Operating under Utah’s Legal Services Innovation Sandbox, Superlegal reviews and redlines construction contracts starting at $117 with turnaround under 24 hours — claiming 90% cost reduction versus traditional firms. Licensed attorneys sign off on every review. Partnered with AGC of America, with clients including BGE, Silverline Construction, and SHN.
Unanet 2026 report: 75% of AEC firms use AI, but only 29% trust the data
The annual AEC Inspire survey of ~300 US leaders found AI adoption jumped 20 points year-over-year. But data confidence lags badly — only 29% report high confidence in the data fueling their AI tools. Industry optimism hit a two-year low at 66%, down from 86% in 2023. Proposal volumes are surging while win rates hold flat at ~50%.

Apple WWDC June 8 — iOS 27 expected to open third-party AI model access. If Apple lets Claude or Gemini run natively on-device, every field worker’s phone becomes an AI endpoint.
