OpenAI has added an automated bid strategy to ChatGPT Ads that sets and adjusts bids without holding a cost target, and it arrives preselected for eligible new ad groups rather than as an option advertisers have to find.

The strategy is called Maximize results. It was listed first among six items in a product update email that OpenAI distributed to advertisers in the ChatGPT Ads Manager Beta during the week beginning Monday, August 17, 2026, the same week the pilot switched on in Mexico and Brazil and the week before European inventory was scheduled to open. The supporting help centre page sits in the Campaign setup collection of the ChatGPT Ads documentation and carries an update stamp of nine days before capture, placing the technical documentation in the second week of August 2026, ahead of the note that told advertisers it existed.

The mechanics are described in plain terms. According to OpenAI, Maximize results is a new bid strategy that lets ChatGPT Ads automatically set and adjust bids on the advertiser's behalf, and it is designed to return as many results as possible from a given budget. The system optimises toward the campaign goal already selected at the campaign level, which the documentation gives as clicks or conversions, and moves bids to maximise that result type within the budget available.

The default is the story

One sentence in the documentation carries more operational weight than the rest of the page combined. For eligible new ad groups, Maximize results is selected by default, and the selection can be reviewed or changed in the ad group's Bid strategy section.

Defaults determine behaviour at scale. An advertiser who reads every field in a campaign builder will notice the preselection and make a decision about it. An advertiser building a fourth ad group at the end of a working afternoon will not. The five-step setup path published by OpenAI makes the sequence explicit: create a campaign in Ads Manager Beta, continue to the ad group step, review Maximize results as the preselected option for eligible new ad groups, choose Manual: Max bid instead if a different strategy is wanted, then complete the ad group and ad setup and launch.

Step three and step four are where control changes hands. Nothing in the documentation describes a notification, an account-level preference, or a way to set the account default to manual once and have it hold. The choice is presented per ad group, every time.

What the strategy explicitly does not do

The most consequential paragraph on the page is a limitation rather than a capability. "Maximize results prioritizes result volume and does not guarantee delivery against a specific CPA, CPC, ROAS, or other cost-efficiency target at this time," the documentation states. Advertisers with a bid limit they need to stay inside are directed to the manual or advanced bid controls in Ads Manager instead.

That sentence separates Maximize results from most of the automated bidding sold across the rest of the market. Target CPA and Target ROAS in Google Ads, Cost Cap in performance social, and the goal-based strategies in the major demand-side platforms all express a number the system is meant to hold. Maximize results expresses volume. The budget is the constraint, and the only constraint. Whatever cost per outcome falls out of the auction is the cost per outcome.

The qualifier "at this time" is doing recognisable work. It signals a roadmap without committing to one, in a product line that has added a capability roughly every three weeks since May.

Result volume optimisation is not unusual on its own. Maximize Clicks and Maximize Conversions have existed in paid search for years, and both behave the same way: spend the budget, chase the count, offer no efficiency promise. What is unusual is the combination of that behaviour with default status on a platform where the underlying auction is young, inventory is thin relative to established channels, and historical cost benchmarks barely exist. Volume maximisation is easiest to evaluate when an advertiser knows what a reasonable cost looks like. In a channel that opened to self-serve buyers in May, few do.

Where it sits in the ChatGPT bidding stack

Before this addition, buying in ChatGPT Ads meant naming a price. The self-serve Ads Manager that opened to all United States businesses on May 5, 2026 introduced cost-per-click bidding alongside the existing cost-per-mille model, with a recommended starting maximum bid of three to five dollars per click and a default maximum of sixty dollars for impression buys. The auction underneath is a relevance-weighted second-price mechanism. OpenAI said at the time that further bidding models would follow, aligned to the outcomes advertisers wanted to optimise for.

Those models arrived in sequence. Cost-per-action buying was activated for a selected group of advertisers in late May. Conversion-optimised campaigns began rolling out on June 5, 2026, gated behind a requirement that an account already have at least one conversion event flowing through either the JavaScript pixel or the Conversions API by June 1. Maximize results is the layer that sits on top of all of it: not a new objective, but a new way of not choosing a bid.

The measurement side matters here in a way that is easy to miss. When Maximize results optimises toward conversions, it optimises toward the conversions the system counts for bidding purposes. View-through conversion reporting appeared in Ads Manager in the same week with a fixed one-day window, and OpenAI walled the metric off from the main conversions total, from cost per acquisition, from billing and from bidding. Post-view credit therefore shows in a column and does nothing to the bid. An advertiser reading a rising view-through number as evidence that automation is working is reading a figure the automation cannot see.

Budget behaviour has also moved. Fixed daily budgets in ChatGPT Ads were converted into seven-day averages during July without an advertiser opt-out, which changes what the budget constraint means at the level of any individual day. Combine averaged pacing with volume-maximising bids and no cost ceiling, and the pairing that results is one in which two of the three variables an advertiser previously controlled now sit with the platform.

Automation defaults across the wider market

The direction is not particular to ChatGPT Ads. Manual bid multipliers were removed from DV360 in May 2025, a change that drew sharp criticism from programmatic buyers who read it as a reduction in platform capability rather than a simplification. TikTok spent early 2026 adding override mechanisms back into its Smart+ automation after advertiser feedback identified control gaps in the original release, a pattern in which initial automation prioritises algorithmic optimisation and later releases restore transparency.

Google has moved in both directions inside a single year. Target CPA and Target ROAS were restored as standalone bidding strategies in June 2026, unwinding a consolidation that had folded them into maximise-style strategies with targets attached. Weeks later, a separate change to how bidding targets are optimised on budget-constrained campaigns took effect on August 17, 2026 across five campaign types, after a public dispute in which advertisers argued that behavioural shifts inside Smart Bidding belong in visible account data rather than in notification emails.

That argument transfers directly. The complaint was never that automation performs badly. It was that when a bidding system changes what it optimises for, advertisers want the change legible inside their own reporting. Maximize results ships with no published documentation on how bids are set, what signals feed the decision, what pacing logic applies, or what diagnostic surfaces exist when delivery behaves unexpectedly.

Why this matters for the marketing community

ChatGPT advertising has moved from a closed pilot with a minimum commitment between two hundred thousand and two hundred and fifty thousand dollars to an open self-serve product in roughly six months. Minimum spend fell to fifty thousand dollars in April and disappeared entirely in May. Reported CPMs dropped from sixty dollars at launch toward the twenty-five dollar range by mid-April. The pilot reached nine markets on August 17, 2026, and European users were told on August 15 that ads would appear on Free and Go plans later in the month. AdRoll opened gated access for selected small, mid-market and business-to-business customers on August 11.

The composition of that incoming advertiser base is the point. A channel that began with premium brands and holding company buyers is now open to accounts with no dedicated bid management resource, arriving into an interface where the bidding decision is already made. Those accounts are also the ones least likely to have a benchmark for what a ChatGPT conversion should cost.

Attribution capacity is uneven across that population. Conversion-optimised buying requires a working pixel or Conversions API connection, and automatic advanced matching became the default on existing web pixels on August 17, 2026 after a ten-day opt-out window. An ad group set to maximise conversions is only as sound as the conversion signal underneath it, and the signal itself has been changing month to month.

There is also a longer-running framing question. OpenAI's monetisation leadership has described a future in which advertisers state a business objective conversationally and the system determines bidding, structure and allocation. Maximize results is a small, concrete step along that line. It removes one field from the campaign builder and moves the decision behind it into the platform, and it does so as the preselected option rather than an opt-in.

For media buyers, the practical shape of the change is narrow and specific. Manual: Max bid remains available in the ad group Bid strategy section, and it remains the only documented route to a hard ceiling on what a click or an impression costs inside ChatGPT Ads. Whether the default holds, and whether cost-efficiency targets arrive to sit alongside it, are the open questions the phrase "at this time" leaves on the page.

Timeline

Summary

Who: OpenAI, through the ChatGPT Ads help centre and a product update email sent to advertisers in the Ads Manager Beta. The change affects media buyers, agencies and self-serve advertisers building campaigns in ChatGPT Ads across the nine markets where the pilot operates, and the European advertisers scheduled to follow.

What: Maximize results, a bid strategy in which ChatGPT Ads sets and adjusts bids automatically toward the selected campaign goal of clicks or conversions, aiming for the largest possible result count within the budget. It is preselected for eligible new ad groups. According to OpenAI, it prioritises result volume and does not guarantee delivery against a specific CPA, CPC, ROAS or other cost-efficiency target at this time. Manual: Max bid remains the alternative for advertisers requiring a bid ceiling.

When: The help centre page carries an update stamp placing its most recent revision around August 12, 2026. The product update email that listed the strategy was distributed during the week beginning Monday, August 17, 2026.

Where: Inside the ChatGPT Ads Manager Beta, at the ad group level, in the Bid strategy section of the campaign setup flow.

Why: OpenAI has added a bidding, targeting or measurement capability to ChatGPT Ads roughly every three weeks since the self-serve platform opened on May 5, 2026, moving from a fixed-price pilot toward a performance channel. Automated bidding without a cost target completes the volume-optimisation layer while leaving efficiency targets for a later release, and shipping it as a default rather than an option determines how the majority of new ad groups will bid.
