2026-10-15 two verticals land on the bundling stack, answering the Sep 10 opening watch that named legal as the next vertical. (1) Sullivan & Cromwell's Agreement Analyzer (openai.com, published Oct 15, no time in the reporting — openai.com/index): developed with OpenAI to identify issues in a draft agreement — company-graded single-engagement case study. (2) The Rosalind Academic Plan (~3:00 PM ET — openai.com/index): eligible academic labs get sponsored access to GPT-Rosalind and life-sciences research tools — the name's first record appearance, adjacent to the Anthropic wet-lab genre and the Gemini 4 Argon science watch. Both announced, not shipped: no customer counts, no eval artifacts, "eligible"/"sponsored" undefined. Watch: Agreement Analyzer proof beyond the single case study, Rosalind's first named labs, GPT-Rosalind science claims held to the validation standard.
2026-09-21 the verticals race gets its analysis layer — Business
Standard reads Astra for Law against Thomson Reuters's in-house
model and Anthropic's verticals; watch items unchanged.
2026-09-17/18 the legal vertical watch item lands — Astra for
Law (openai.com, ~8 PM ET Sep 17): frontier intelligence for law,
custom firm workflows, connected legal data sources, legal-grade
controls for confidential client work. Customer-proof layer same
window: Cooley "GO Public" on ChatGPT Work (IPO work, openai.com
case study). Verticals now two-sided and two-deep: OpenAI (financial
services, legal, health) vs Anthropic (financial advisors, LSVP).
Next watch: Anthropic's legal answer, pricing/controls detail,
whether the Harvey relationship deepens or competes.
