Is Claude better than ChatGPT for private equity?

For most deal teams, Claude is the better everyday tool, because most deal work is reading. A deal team spends its week in CIMs, quality of earnings reports, management presentations and credit agreements, and the value is in spotting what does not add up. Claude is the more careful reader of long documents, and it is quicker to say a document does not answer your question than to fill the gap with a guess.

Anthropic has also built for private equity directly. Its free private equity plugin for Claude has commands for screening a deal, building a diligence checklist, drafting an IC memo and checking returns. Claude connects to PitchBook, FactSet, S&P Global and Daloopa if you already license them, and Claude for Excel works inside your model and points to the cells behind each answer.

ChatGPT is the broader tool. It is quick at market research, brainstorming and turning rough notes into a clean first draft. OpenAI's ChatGPT for Financial Services, launched in September 2026, comes with PitchBook, Daloopa, LSEG News and Crunchbase data built in, but it was built for investment banks and equity research first and is sold to eligible institutions with no public price. ChatGPT also has its own Excel add-in.

On price, they are level. Claude Team and ChatGPT Business both cost $20 a seat a month billed annually, and neither trains on your data by default on those plans. The free and personal plans are the real risk, because both can train on what you paste unless someone switches that setting off. Whichever you pick, move the deal team off personal accounts first.

A fair rule: Claude if your week is CIMs, data rooms and models; ChatGPT if your team already lives in it and wants the bundled data. Plenty of firms pay for both and give each a lane. Before you buy seats, run both on a deal you already closed, where you know the right answers, and keep the one that gets more of them right.
