Claude vs ChatGPT for business: as of November 12, 2026, price will not help you choose. Claude Team and ChatGPT Business list the same rate to the dollar, $20 per seat per month on annual billing and $25 on monthly billing. Microsoft 365 Copilot blurs the duel, because its Researcher agent lets people pick between GPT models and Claude models. Yet Microsoft keeps those Claude models outside the EU Data Boundary, the geographical area it defines in the European Union to store and process customer data. So the decision happens elsewhere: your daily tools, Europe, account administration and team size.
The right first trial depends on your profile
Take a 50-person company that runs on Microsoft 365 and wants an AI assistant for everyone. It will serve as the running example, and its first trial depends on what it needs most.
- You want advanced administration at a listed price: try Claude. Claude Team covers 2 to 150 people, and Claude Enterprise adds automated account management and audit logs, from 20 seats, self-serve.
- You must keep storage and inference in Europe: try ChatGPT Enterprise or Copilot. OpenAI documents both for eligible Enterprise customers, on a quote. Microsoft keeps Copilot traffic inside the EU Data Boundary, except Anthropic models and web search.
- Your teams live in Word, Excel, Outlook and Teams: try Microsoft 365 Copilot. Copilot Chat is already included at no additional cost with an eligible Microsoft 365 subscription, and the paid licence comes next.
The Claude, ChatGPT, Copilot order follows the "claude vs chatgpt" search, not a ranking.
The next step is to check what the vendor pages say, word for word.
Claude vs ChatGPT vs Copilot: the gaps fit in one table
When an official page says nothing, the cell says so. That silence becomes a question to put to the vendor.
| Criterion, as of November 12, 2026 | Claude | ChatGPT | Microsoft 365 Copilot |
|---|---|---|---|
| Team size | Team: 2 to 150 people | Business: 2 to 200 employees | Copilot Business: Business plans, which the page describes for up to 300 users. Microsoft 365 Copilot: not stated |
| Price per seat per month, paid annually | Team: $20 (Standard), $100 (Premium) | Business: $20 (Standard), $100 (Premium) | Copilot Business: from €18.20 excl. VAT, €15.60 excl. VAT on promotion. Microsoft 365 Copilot: €26.00 excl. VAT |
| Price per seat per month, paid monthly | Team: $25 (Standard), $125 (Premium) | Business: $25 (Standard), $125 (Premium) | Copilot Business: €21.84 excl. VAT. Microsoft 365 Copilot: €27.30 excl. VAT, with an annual subscription |
| Large-account plan and minimum | Enterprise: $20 per seat per month, billed annually, 20 seats minimum, plus usage at API rates | Enterprise: custom pricing through the sales team, minimum not published | Microsoft 365 Copilot, minimum not stated, eligible Microsoft 365 licence on top |
| SSO (single sign-on) | Team and Enterprise | Business and Enterprise (SAML) | Not detailed in the pages read |
| SCIM and logs | Enterprise yes, Team no | Enterprise yes, Business no | Not detailed in the pages read |
| Training on your data | None by default | No, for Business and Enterprise | No, prompts and responses excluded |
| Storage and inference in Europe | App: nothing in the pages read. Through AWS Bedrock and GCP Vertex: yes | Enterprise: storage and inference, eligible customers. Business: storage alone, rolling out gradually | EU Data Boundary, Anthropic models excluded |
| Microsoft 365 integration | Claude for Microsoft 365 and Claude for Microsoft Outlook | Connection to Microsoft 365, extensions for Excel, Word and PowerPoint | Built into Word, Excel, PowerPoint, Outlook and Teams |
| Models listed | Fable (Premium seats), Opus, Sonnet, Haiku | GPT-6.1 Sol, GPT-6 Astra, GPT-6 Sol, GPT-6 Luna, among others | GPT models from OpenAI and Claude models from Anthropic in Researcher |
A word on taxes. Anthropic states that its prices do not include applicable taxes, and Microsoft's French page shows amounts before VAT. The OpenAI pages read say nothing about taxes.
With Claude, the price stays public up to the Enterprise plan
Claude Team is built, according to Anthropic's pricing page, for teams of 2 to 150 people. The Premium seat, at $100 or $125 depending on billing, gives 5x the usage of a Standard seat.
The Team plan already includes single sign-on, or SSO, which lets your staff log in with their company account. It also includes Claude for Microsoft 365 and Claude for Microsoft Outlook. Claude Code is included in every paid plan and shares the plan's usage limits, and a separate guide explains how to roll out Claude Code to a team of developers.
Claude Enterprise changes the billing logic, which Anthropic sums up as seat price plus usage at API rates. The seat costs $20 per month, billed annually, with a 20-seat minimum, and usage comes on top at a cost that varies by model and task. In return, Anthropic's table reserves for Enterprise, among other things, three features that Team lacks:
- SCIM, the protocol that creates and removes accounts from your company directory;
- audit logs;
- role-based access, or RBAC, which sets the permissions of each profile.
With 50 people, you clear the 20-seat minimum and you can start self-serve, yet your budget still depends on usage the page does not price in advance.
On Europe, the Claude API documentation offers two values for where inference runs: global, or the United States.
ChatGPT Business goes up to 200 people, Enterprise goes through sales
ChatGPT Business targets, according to OpenAI's pricing page, teams of 2 to 200 employees. The OpenAI Help Center gives the prices, and they match Claude Team to the dollar: $20 or $25 for a Standard seat, $100 or $125 for a Premium seat. OpenAI notes that pricing may vary by country and currency. Check the amount shown for your country at checkout.
ChatGPT Enterprise shows no price. The page points to the sales team for custom pricing, and OpenAI's table reserves SCIM, role-based access controls and data residency for that plan. That choice fills a whole article, the guide to choosing between ChatGPT Business and Enterprise.
Two points deserve your attention before you sign. The first is usage: the pricing page announces that, starting in December, plan usage will have a shared limit across ChatGPT and Codex. If your teams use both, usage of one will count alongside usage of the other.
The second is Europe. The pricing table answers "No" on the data residency row for Business, yet a Help Center article announces a gradual rollout, "not yet available to all customers". Both texts stand. So ask OpenAI where your account is.
That leaves the third candidate, the one you may already pay for.
Copilot is paid on top of Microsoft 365, except Copilot Chat
Microsoft describes Copilot Chat as included "at no additional cost" for Microsoft Entra account users with an eligible Microsoft 365 subscription. If your 50-person company holds that subscription, the first trial costs nothing more.
Microsoft then sells two paid licences. On Microsoft's French page, Microsoft 365 Copilot costs €26.00 excl. VAT per user per month, paid annually, and the page adds that a separate licence for an eligible Microsoft 365 plan is required. Microsoft 365 Copilot Business starts at €18.20 excl. VAT, cut to €15.60 excl. VAT by a promotion. Microsoft frames that discount, which runs from July 1 to December 31, 2026 and applies to the first year. The add-on itself is available only to existing Microsoft 365 customers with an eligible Business plan.
Copilot is not quite a rival to ChatGPT. Researcher, one of Copilot's agents, supports GPT models from OpenAI and Claude models from Anthropic, so Claude becomes reachable from Copilot, provided your admin allows it.
That choice has a cost in Europe. Microsoft Learn states that Claude models deployed in Copilot are "currently excluded from the EU Data Boundary". For customers in the EU, EFTA and the UK, Microsoft disables them by default. An admin holding the AI Administrator or Global Administrator role has to enable them in the admin center, then choose the users concerned.
The default setting can move. On November 10, 2026, The Register ran the headline that Microsoft is giving Claude the keys to UK Copilot tenants by default. The Microsoft Learn page read on November 12 still shows Claude disabled by default in the UK. So check that setting in your own admin center.
On your data, Europe separates the three vendors
Your security lead and your data protection officer will ask three questions. Does your content train the models? Where is it stored? Where does inference run, meaning the computing of each answer?
Claude. Anthropic's pricing page states, for Team and for Enterprise, that your content is not used for model training by default. On location, the API documentation offers global, the default, or the United States for inference, and the United States alone for storage. For Europe, Anthropic points to AWS Bedrock and GCP Vertex, whose regional endpoints keep storage and processing in the chosen region. Those are cloud platforms, and the pages read describe no European option for the Claude Team app.
ChatGPT. OpenAI's table answers "No" on the training row, for Business and for Enterprise. On location, the Help Center lets eligible new Enterprise customers store content at rest in a chosen region, Europe included. Inference in Europe comes on top for eligible Enterprise customers with data residency enabled. Business lags behind: its residency, still rolling out, covers storage and leaves inference out. For a region outside the United States, OpenAI also keeps a copy of every prompt and response in the United States for a limited time.
Microsoft 365 Copilot. Microsoft writes that prompts, responses and data accessed through Microsoft Graph are not used to train foundation models. European traffic stays within the EU Data Boundary, with two exceptions: Anthropic models and web search queries.
So training separates nobody. Europe does. Budget comes next.
At 50 people, Claude and ChatGPT cost the same amount
Back to the running example: 50 seats, list prices, annual commitment, twelve months. This calculation stays theoretical: it counts neither negotiation nor tax.
| Plan, list price as of November 12, 2026 | Calculation | Total over one year |
|---|---|---|
| Claude Team, Standard seat, annual | 50 × $20 × 12 | $12,000 |
| Claude Enterprise, seats alone | 50 × $20 × 12 | $12,000, plus usage at API rates |
| ChatGPT Business, Standard seat, annual | 50 × $20 × 12 | $12,000 |
| Microsoft 365 Copilot Business, starting price, annual | 50 × €18.20 × 12 | €10,920 excl. VAT |
| Microsoft 365 Copilot Business, promotion, first year | 50 × €15.60 × 12 | €9,360 excl. VAT |
| Microsoft 365 Copilot, annual | 50 × €26.00 × 12 | €15,600 excl. VAT |
On the ChatGPT vs Claude duel, the calculator calls a draw. The Copilot rows are in euros, and this article converts no currency. Above all, they come on top of the eligible Microsoft 365 licence, which you pay separately.

Four questions are enough to decide
Ask these questions in this order: each one removes options before the next.
- Do your teams work in Microsoft 365 and want AI in Word, Excel, Outlook and Teams? If so, start with Copilot Chat, already included, then price the Copilot licence for the roles that need it.
- Must you keep storage and inference in Europe? If so, ChatGPT Enterprise documents both, and Copilot stays within the EU Data Boundary, web search aside, as long as Anthropic models stay disabled. For the Claude app, ask Anthropic for a written commitment.
- Do you need SCIM and audit logs? If so, aim for Claude Enterprise, at a listed price from 20 seats, or ChatGPT Enterprise, on a quote, because Team and Business do not offer them.
- How many people are you equipping? From 2 to 150, Claude Team fits, and ChatGPT Business goes up to 200. Beyond that, look at the Enterprise plans.
The 50-person company wanted a price to choose by, and it found two identical tags. Price decides nothing. Its answers do. It works in Microsoft 365, so it opens Copilot Chat this week. In parallel, it sends the same questions to the three vendors: where inference runs, who administers the accounts, what usage costs beyond the seat.

FAQ
Claude or ChatGPT: which one should a business choose?
Between Claude and ChatGPT, price does not settle it: Claude Team and ChatGPT Business both cost $20 per seat per month on annual billing, as of November 12, 2026. Choose Claude if you want SCIM and audit logs at a listed price, with Claude Enterprise from 20 seats. Choose ChatGPT Enterprise if you must keep storage and inference in Europe.
Does Microsoft Copilot use ChatGPT?
The Microsoft pages read on November 12, 2026 do not mention ChatGPT, the OpenAI product. They mention models: the Researcher agent in Microsoft 365 Copilot supports GPT models from OpenAI and Claude models from Anthropic. For Claude, an admin must first allow Anthropic models in the Microsoft 365 admin center.
Is my data used to train the models?
None of the three vendors trains its models on your data by default, according to the three vendors' pages read on November 12, 2026. Anthropic states it for Claude Team and Enterprise, OpenAI for ChatGPT Business and Enterprise. Microsoft writes that Microsoft 365 Copilot prompts and responses are not used to train foundation models.
Can you keep your data in Europe?
Yes, with different limits for Claude, ChatGPT and Microsoft 365 Copilot. Claude keeps storage and processing in Europe through AWS Bedrock and GCP Vertex, two cloud platforms. ChatGPT Enterprise documents storage and inference in Europe for eligible customers, while ChatGPT Business stops at storage, rolling out gradually. Microsoft 365 Copilot relies on the EU Data Boundary, from which Microsoft excludes Anthropic models.
How much does Claude, ChatGPT or Copilot cost per user?
As of November 12, 2026, Claude Team costs $20 per seat per month on annual billing and $25 on monthly billing, and ChatGPT Business lists the same prices. On Microsoft's French page, Microsoft 365 Copilot costs €26.00 excl. VAT per user per month, paid annually, and Copilot Business starts at €18.20 excl. VAT. Both Copilot licences come on top of an eligible Microsoft 365 subscription.
Is Copilot Chat free?
Copilot Chat is included at no additional cost with an eligible Microsoft 365 subscription, according to Microsoft. So "free" depends on that subscription. Copilot inside Teams, Word, Excel and PowerPoint requires a paid Copilot licence, while Copilot Chat also includes Copilot for Outlook.
