AI vendor switching in 2026 is bound primarily by contract terms — exit clauses, data-portability obligations, model-deprecation rights — not by technical migration cost. Seven clause patterns repeatedly create the lock-in most enterprises only discover at year two of the relationship: (1) data-portability scope narrowness, (2) model-deprecation rights without credit, (3) sub-processor expansion without consent, (4) output-IP ambiguity, (5) pricing-tier rebalancing mid-contract, (6) agent-uptime SLA definition gaps, (7) audit-evidence retention obligations. Vendor consolidation (Moveworks→ServiceNow Dec 2025, Aisera→Automation Anywhere Nov 2025) and model deprecations make this a 2026 procurement story.
Procurement-anxiety lead-magnet piece, paired with RES-005 (AI MSA Red-Team Checklist downloadable). Cadence 60-day. Trigger conditions: further major AI vendor M&A activity changing change-of-control clauses; new EU AI Act enforcement guidance on Article 16 audit-evidence retention; first major published settlement under model-deprecation clauses; SaaS-industry MSA template revisions. Sister claims: AM-027 (vendor contract gotchas), AM-085 (RFP 60 questions), RES-005 (MSA red-team). External sources cited inline: ServiceNow Q1 2026 10-Q, Automation Anywhere Aisera press, Klarna Bloomberg reversal, OpenAI deprecation page, Anthropic model lifecycle, EU AI Act Articles 12 and 16.

About this register
The Reporting register tracks claims published from articles addressed to senior enterprise IT leaders — CIOs, IT directors, heads of platform. Claims are reviewed on a 30–90 day cadence; each review either reaffirms the claim, marks one substantive part as Partial, or marks it Not holding once the underlying evidence has been overtaken.
Recent corrections in Reporting
- AM-008 · Partial · 17 Jun 2026
Source-text figure re-review: Google's 2024 Environmental Report reports a 28% year-over-year increase to 8.1 billion gallons, not the 33% (from a 6.1 billion 2023 base) asserted at publish. The 8.1B 2024 figure and the Microsoft WUE 0.30 L/kWh / 39%-improvement figure are unchanged and verified. Article corrected to 28% and the unsupported 6.1B base removed; the claim text retains the original figure with this correction per the Holding-up protocol.

One of four legs unanchored on re-review. The claim text attributes '12% of deployments clearing 300%+ ROI with 88% at or below break-even at 12-18 months' to the Stanford DEL 2026 Enterprise AI Playbook. Full-text verification on 10 Jun 2026 found no such figure in that source: the playbook (Pereira, Graylin, Brynjolfsson, Apr 2026) studies 51 successful deployments by design and contains no ROI distribution, no 300%-plus cohort, and no break-even measurement point (full finding at AM-029, correction of 10 Jun 2026). The only verified figure carrying the same 12/88 numerals is IDC research with Lenovo (via CIO.com, Mar 2025): roughly 88% of AI proof-of-concepts never reach production and roughly 12% graduate — a pilot-to-production graduation metric, not an ROI distribution. The Gartner 28%, McKinsey 23%/17%, and MIT NANDA 95% legs verify; they support a small high-performing tail and a large struggling body, but none documents the two-peak bimodal shape the claim asserts. Status Up -> Partial.
- AM-129 · Partial · 10 Jun 2026
One of three read-against anchors unanchored on re-review. The claim text cites 'Stanford Digital Economy Lab Enterprise AI Playbook (12/88 bimodal ROI distribution at 12-18 months)' and frames the realistic ROI band around 'the highest-discipline 12% cohort'. Full-text verification on 10 Jun 2026 found the playbook contains no 12/88 distribution, no bimodal ROI shape, and no 12-18-month ROI measurement point (full finding at AM-029, correction of 10 Jun 2026). The claim's core negative finding — no mid-market enterprise has produced a documented +240% ROI in 90 days under audited conditions — is unaffected; the McKinsey State of AI 2025 and MIT NANDA legs verify and continue to support it. The '12% cohort' framing has no verifiable referent. The only verified figure carrying the 12/88 numerals is IDC's pilot-graduation finding (roughly 88% of AI proof-of-concepts never reach production; via CIO.com, Mar 2025), a different metric. Status Up -> Partial.
