SIWC and OpenAI Marketplace: Order Form Lines

(OpenAI DevDay Recap Sep 29 2026 + TechCrunch same day): Sign in with ChatGPT lets eligible usage count toward plan limits across 16 partners (named: Devin, Notion, Vercel, T3, OpenClaw, Dactyl) with per-partner controls. OpenAI Marketplace lets eligible enterprise customers apply part of their existing OpenAI commitment toward approved partner software across a first 32 partners that include HubSpot, Salesforce, and ServiceNow (also Figma, Adobe, Sierra, Decagon, Harvey, Legora, Palo Alto Networks, CrowdStrike, Baseten). Customers express interest; not a self-serve toggle. No dollar share, cap, or revenue-share percent is published. Do not mash the 16 and 32 lists. Map Order Form lines for SIWC burn, Marketplace commitment redirect, per-app caps, and chargeback / accepted-outcome owners before agent volume scales.

Why trust this analysis?

The short answer

When OpenAI can apply part of our commitment to Salesforce/HubSpot partner software, and Plus/Pro allowance burns inside partner apps against plan limits, which Order Form line, per-app cap, and chargeback owner must we name before agents scale?

Per OpenAI DevDay Recap (Sep 29 2026) and TechCrunch (1:15 PM PDT Sep 29): Sign in with ChatGPT makes eligible OpenAI usage count toward plan limits across 16 partners (OpenAI names Devin, Notion, Vercel, T3, OpenClaw, Dactyl) with controls on how much each can use. OpenAI Marketplace lets eligible enterprise customers apply part of their existing OpenAI commitment toward approved partner software; first 32 partners include HubSpot, Salesforce, ServiceNow, Figma, Adobe, Sierra, Decagon, Harvey, Legora, Palo Alto Networks, CrowdStrike, and Baseten. Application / express-interest gated, not a self-serve toggle. OpenAI has not published the commitment-share percent, dollar cap, or revenue-share math. Tag undisclosed share % as VENDOR / UNDISCLOSED. Require Order Form lines for: (1) SIWC eligibility and which Plus/Pro/Business entitlements burn; (2) per-partner SIWC caps; (3) Marketplace eligibility and which commitment dollars can redirect; (4) named partner SKUs (Salesforce/HubSpot/etc.) funded from OpenAI commitment; (5) chargeback owner for SIWC burn vs Marketplace redirect; (6) accepted-outcome owner for revenue work changed. Soft-open unpublished share % and SKU strings until AE/paper.

Decision rule

Keep SIWC (16 / plan limits) and Marketplace (32 / part of commitment) on separate Order Form lines. Name chargeback and accepted-outcome owners before Plus/Pro allowance and commitment dollars move off ChatGPT into partner apps.

Evidence

  • OpenAI DevDay 2026 Recap: SIWC across 16 partners (Devin, Notion, Vercel, T3, OpenClaw, Dactyl); eligible usage counts toward plan limits; Marketplace: eligible enterprises apply part of existing OpenAI commitment toward approved partner software; first 32 partners include HubSpot, Salesforce, ServiceNow, Figma, Adobe, Sierra, Decagon, Harvey, Legora, Palo Alto Networks, CrowdStrike, Baseten
  • TechCrunch Sep 29 2026 1:15 PM PDT: SIWC 16 launch partners; Marketplace 30-plus partners including HubSpot, Salesforce, ServiceNow; eligible customers apply part of OpenAI commitment; no billing/revenue-share system announced comparable to traditional app stores
  • OpenAI community DevDay announcements: eligible subscription usage at 16 partners and enterprise commitment applied to Marketplace partner products

Operator action

This week: split SIWC vs Marketplace on the Order Form. List which seats/entitlements SIWC can burn, per-partner caps, which commitment dollars Marketplace can redirect, named partner SKUs (Salesforce/HubSpot), chargeback owner, and accepted-outcome owner. Do not approve agent scale until those lines are named. Tag commitment-share % VENDOR / UNDISCLOSED until paper.

When OpenAI can apply part of our commitment to Salesforce/HubSpot partner software, and Plus/Pro allowance burns inside partner apps against plan limits, which Order Form line, per-app cap, and chargeback owner must we name before agents scale?

The Pro 200 capacity cliff, Anthropic commitment discount cliff, GPT-6 / Opus token price cut, and HubSpot seats and credits each have their own billing question. Here, two new OpenAI programs move spend across company boundaries: subscription allowance used inside a partner app and enterprise commitment applied to partner software. The separate limits and owners belong on paper before an agent uses either path at scale.

What DevDay put on paper

Sign in with ChatGPT (SIWC). The OpenAI DevDay recap and OpenAI community announcement describe eligible subscription usage in partner products. The community summary says: ‘Eligible subscription usage can also be used through 16 launch partners.’ TechCrunch names Devin, Notion, Vercel, T3, OpenClaw, and Dactyl. Eligible usage counts against plan limits, with controls over how much each partner may use. Confirm Plus, Pro, and Business entitlement details for the account in writing.

OpenAI Marketplace. The OpenAI community announcement says: ‘OpenAI Marketplace lets eligible enterprise customers spend part of their OpenAI commitment on partner products.’ The Marketplace launches with a first group of 32 partners, including HubSpot, Salesforce, ServiceNow, Figma, Adobe, Sierra, Decagon, Harvey, Legora, Palo Alto Networks, CrowdStrike, and Baseten. TechCrunch describes more than 30 partners and reports the ability to apply part of an existing commitment to approved partner software. Customers express interest and confirm eligibility; this is not a self-serve toggle.

The two meters

Keep subscription allowance and enterprise commitment separate

SIWC and Marketplace need different contract lines and chargeback owners. Source-cited charts live in the research library.

Split diagram comparing Sign in with ChatGPT subscription allowance at 16 launch partners with OpenAI Marketplace commitment spending at 32 launch partners. The programs have separate eligibility and meters.

Two lists, two meters. Do not merge the 16 SIWC launch partners with the 32 Marketplace partners. SIWC draws eligible subscription allowance against plan limits. Marketplace redirects part of an eligible enterprise commitment to approved partner products. Neither the commitment-share percentage nor a dollar cap or revenue-share formula is published in the cited launch receipts. Write VENDOR / UNDISCLOSED for that field, not a guessed number.

Schematic two-column Order Form map. Sign in with ChatGPT: 16 launch partners, eligible Plus or Pro allowance counts toward plan limits, per-partner controls. OpenAI Marketplace: 32 launch partners, part of enterprise commitment can fund approved partner software including Salesforce and HubSpot, express-interest access, commitment share vendor undisclosed. Separate programs and separate meters.
Two programs, two Order Form lines. Partner counts describe different lists; schematic, not a dataset.

Decision rule for Director+ RevOps / Finance

Schematic Order Form worksheet: existing OpenAI commitment feeds an approved Marketplace partner SKU such as Salesforce or HubSpot; the commitment share is vendor undisclosed. The business unit chargeback owner and accepted-outcome owner must be named; Sign in with ChatGPT allowance burn is tracked separately.
Chargeback worksheet for a Marketplace redirect. Fill the commitment share and named owners from the contract, not from a launch announcement.
  1. Split the programs. Put SIWC allowance burn and Marketplace commitment redirect on separate Order Form lines; record separate eligibility and usage statements.
  2. Name SIWC entitlements. Which Plus, Pro, or Business seats can use it? Which partner apps count against which plan limits? Confirm account and regional eligibility.
  3. Set per-app controls. Record each partner's limit, alert, reset window, and the person who can change its cap. Request paper where controls are not specified.
  4. Name redirectable commitment. Specify which contracted OpenAI commitment dollars Marketplace can use, the approval step, and the share. Keep share % as VENDOR / UNDISCLOSED until written terms arrive.
  5. List approved partner SKUs. Salesforce and HubSpot are named launch partners, but their applicable software SKU and availability for your agreement need written confirmation.
  6. Assign two chargeback owners. Name who pays for SIWC subscription allowance consumption and who books Marketplace commitment redirected to a partner SKU.
  7. Assign an accepted-outcome owner. Name the revenue or operations leader who signs off on the work changed, independently of the billing owners. Do not scale until all owners and caps are named.

Quick compare

  • SIWC: 16 launch partners; eligible plan allowance follows the person into a partner app and counts against plan limits. Per-partner controls need an owner.
  • Marketplace: First 32 partners; eligible enterprise customers can apply part of an existing OpenAI commitment toward approved partner software. Access requires expressed interest and confirmation.
  • Undisclosed: Commitment-share %, dollar cap, revenue-share math, and your contracted partner SKU. Keep these fields open until paper.
  • Other decoders: Pro 200 capacity covers a shrinking seat allowance; Anthropic cliff covers API commitment overage; GPT-6 / Opus covers token unit price; HubSpot seats and credits covers HubSpot's own pool. This piece covers cross-app allowance burn and OpenAI commitment redirect.
