LiveRamp lets brands target their own customer lists in ChatGPT Ads

What the integration does

LiveRamp announced on 28 September 2026 that its RampID identity resolution now powers Custom Audiences inside ChatGPT Ads across 11 markets, letting brands connect CRM, loyalty, behavioural, web and app data to campaigns inside the chat interface for the first time.^[1] Brands can upload first-party data, email addresses, phone numbers and the like, and either target or suppress those audiences at campaign level.^[2]

The targeting mechanics sit inside OpenAI's Ads Application Programming Interface (API). Campaigns include or exclude Custom Audiences via targeting.custom_audiences.ids and targeting.excluded_custom_audiences.ids fields, and bid multipliers run from 0.1× to 10× at ad-group level on both cost-per-mille (CPM) and cost-per-click (CPC) buys.^[3] A buyer sitting on a high-value donor or loyalty segment can bid ten times more aggressively against that audience than the campaign floor, a degree of control that has not existed on this channel before.^[4]

From measurement to targeting: how LiveRamp got here

LiveRamp became OpenAI's first conversion measurement partner on 10 June 2026, connecting its Signal Hub infrastructure to ChatGPT Ads via a secure, server-to-server Conversions API.^[5] The September 2026 audience activation announcement extends that deal, so the same identity graph that measured conversions now also determines who sees the ad in the first place.

Megan Morris, Director of Integrated Media Solutions at Allegiance Group and Pursuant, is an early adopter of the combined measurement and targeting setup. "We're continually optimizing the channels we use to reach our customers, and with ChatGPT Ads becoming an increasingly popular engagement surface for donors, it's important for us to view the omnichannel impact of our ads across all of our investments," Morris said.^[1] Morris said working with LiveRamp and ChatGPT makes it easier to "reach ChatGPT's considerable user base, while easily making the right strategic decisions for our strategy and every other platform we advertise on."^[1]

ChatGPT Ads began as a US-only pilot on 9 February 2026, expanded to Australia, New Zealand and Canada on 16 April 2026, making ads available to Free and Go tier users in those regions, and added self-serve cost-per-click buying in May 2026.^[6] The LiveRamp measurement deal in June and the September audience activation announcement are the third and fourth phases of that build-out.

The Australian compliance question

Australia's Privacy Act tranche-two draft, released 31 August 2026, defines direct marketing to cover any targeted communication by any means, including programmatic, pixels and cookies, and requires consent for trading in personal information. Uploading a CRM list to ChatGPT Ads Custom Audiences and matching it through RampID looks likely to fall inside that definition, though the draft can still change.

Whether Australia is among the 11 named markets has not been confirmed by LiveRamp or OpenAI. The integration announcement names 11 markets without listing them individually, so local teams should verify access before building activation plans around this capability.

The precision-targeting argument for Australia also sits alongside earlier engagement data. Our earlier analysis found Brazilians click ChatGPT Ads at nearly three times the rate of Australians, which frames the local opportunity as an audience-quality play rather than a volume one. A 10× bid multiplier on a tightly matched loyalty segment makes more sense in that context than broad reach would.
