Cycle on Sep 28, 2026

I'll start by reviewing the open threads and existing notes for this topic, then gather fresh evidence.

I have a rich existing note set (30 notes) and 5 open watches. The most time-sensitive one is the **GSA GSAR 552.239-7001 final rule** (fire date Oct 1, 2026 — three days away). Let me check that watch plus scan for fresh developments in the past week on enterprise AI buying criteria.

The GSA clause appears still in draft ("published in draft on June 17 and still not final"). Let me verify directly on the Federal Register and chase the IDC September 2026 research lead on AI-mediated B2B buying.

The Federal Register API response didn't render its JSON payload. Let me try the regular search page, and also fetch the Vertice "Ana" AI negotiation agent launch — a buy-side AI agent for software procurement is a notable new development for this topic.

Two good leads: the Vertice "Ana" launch (Sept 8, 2026) is concrete evidence of buy-side AI agents in software procurement, and the Federal Register search rendered ambiguously (may show 0 results). Let me verify the GSAR status via the API properly, and hunt for the IDC September 2026 research primary source.

Confirmed: the only Federal Register document for the GSAR clause is the June 17, 2026 proposed rule — **no final rule yet**, so that watch hasn't fired. Now let me dig for the IDC September 2026 primary source and check review-platform and consolidation developments.

Strong leads: an Outsell Inc. August 2026 B2B Buyers Study on AI's limitations in vendor selection, and IDC 2026 buyer survey stats (68% use AI always/often to compare vendors). Let me chase the primary sources.

The 68%/46%/website-decline stats are attributed to both Outsell and IDC in secondhand posts — I need to pin down the actual source. Let me fetch the newsletter that cites it and check Outsell's own site.

The newsletter links IDC's own blog as the primary source for the 68%/70%/46% buyer stats. Let me fetch it, plus the Carbon study of 189 B2B buyers.

I have three evidence bases fetched and confirmed this cycle (IDC buyer data, Carbon's buyer study, Vertice's Ana launch) plus a verified GSAR status check. Now I'll persist the findings — three notes, one per subject.

First note saved; the second call went out malformed (empty). Writing the Carbon and Vertice notes now.

All three findings are persisted. Now recording the open Outsell thread and registering a watch on IDC's recurring buyer-data series.

The watch registered. The thread kind "investigation" was rejected — retrying with kind "question".

All bookkeeping is done. Summarizing the cycle and closing it out. **This cycle's findings:** 1. **IDC's 2026 buyer data** (new note, `idc-ai-mediated-buyer-journey-2026`) — 68% of buyers use AI always/often to compare vendors; vendor-website evaluation usage collapsed from 66% to 37%; only 33% still rely on the salesperson; **90% of enterprise legal buyers now write AI clauses** that formally trigger challenges to unsupported claims; only 3.1% of vendor orgs are at optimized AI maturity. 2. **Carbon's 2026 B2B Buyer's Report** (new note, `satisfied-but-reconsidering-b2b-buyers`) — the satisfaction paradox: 94% satisfied, yet 59% will reconsider a partner within 12 months; 57% already use AI for side-by-side provider comparison; top switch triggers are value (59%) and proof of ROI (39%). 3. **Vertice's "Ana" launch** (update to `agentic-procurement-commerce-shift`) — the first at-scale buy-side AI negotiation agent (4,000+ live negotiations, 18% average savings, trained on 250K+ contracts), operationalizing Gartner's 90%-agent-intermediated-by-2028 forecast. Renewals will increasingly be run against benchmark-armed agents. **Watch status:** Verified on the Federal Register that the GSA GSAR 552.239-7001 final rule has **not** published (only the June 17, 2026 proposed rule exists) — that watch stays open for its Oct 1 check. Also registered a new ongoing watch on IDC's annual buyer-journey data refresh, and opened a thread to locate the primary Outsell 2026 B2B Buyers Study publication.

Cycle complete. Three findings persisted (two new, one revision), one new watch registered, one investigation thread opened, and the GSA final-rule watch confirmed as not yet fired — it stays open for the October 1 check.
