Kids and family advertisers plan around key moments, often putting more budget behind periods of peak demand. But the challenge we keep hearing from buyers isn’t seasonal: it’s how they buy this inventory at all, any time of year.
Most brands advertising to children aren’t doing it programmatically. They buy direct. They run it through YouTube and let the platform’s own labeling do the compliance work. Or they do buy it programmatically, but compliance and trust rest on a publisher’s self-declared kids-safe flag, and on every downstream partner honoring it, with no independent verification in place.
That’s not a knock on those buyers. Programmatic pipes for this inventory mostly don’t exist, or don’t hold up.
Access, Not Regulation, Keeps Buyers Out of Programmatic
Ask a buyer why they avoid programmatic child-directed inventory and regulation usually isn’t the first thing they say. Access is.
This inventory has never been available programmatically at scale. Publishers with kids’ content default to direct deals or platform buys, partly because programmatic infrastructure hasn’t kept pace with how fast the rules keep shifting. This isn’t just a Children’s Online Privacy Protection Act (COPPA) problem. A growing list of state laws layer on their own thresholds and restrictions, and they don’t even agree on who counts as a child — some cap it at 12, others extend protections to 15, 16, or 17.
These laws generally permit advertising to kids and teens, but do so only within specific parameters, such as making sure that advertising is purely contextual and does not use personal data from kids or teens for targeted advertising. The responsibility of advertising within those parameters typically sits with the brand, and doing so at bid-request speed is a taller order than most buyers want to contend with in a constantly evolving landscape. Building a bidstream that holds up against that kind of moving target — and stands up to scrutiny with real proof points rather than just a black box or “trust me bro” mentality — is real infrastructure work. Most of the industry hasn’t done it.
And the regulations continue to evolve, making it difficult for buyers to feel fully confident in their own solutions. The Federal Trade Commission’s (FTC) amended COPPA rule had a compliance deadline on April 22, 2026. The KIDS Act, which would extend protections past age 13 to include minors under 18 and put real limits on targeted advertising to minors, cleared the House this summer with rare bipartisan support. Age verification acts and age appropriate design codes continue to pass across the U.S. and beyond. Managing that level of ongoing risk requires significant, continuous work.
So buyers pick the option that feels safest, which is usually the one that avoids programmatic entirely.
Why Sensitive Categories Demand Real Infrastructure
This space is hard and it’s not getting easier. Every layer — onboarding publishers, building the bidstream, enforcing targeting rules, vetting creatives — has to hold up to more scrutiny every year, not less.
Getting a compliant path into programmatic child-directed inventory took real engineering work, not a policy memo bolted onto existing pipes.
Taking on that burden is what makes responsible media possible. When the right controls are built into the supply path and maintained over time, publishers can continue funding child-directed content in a way parents can feel comfortable with, helping ensure that high-quality content remains available to kids.
What the OpenX Child-Safe Marketplace Includes
The OpenX Child-Safe Marketplace is a curated programmatic path to child-directed CTV inventory in which every publisher and buyer is individually vetted, deals run as private marketplace deals, targeted advertising is blocked by design, and the framework is audited by PRIVO, an FTC-approved COPPA Safe Harbor.
- Sell-side and buy-side vetting: publishers and buyers are individually approved and connected via private marketplace deals.
- Data minimization: personal data use is restricted and targeted advertising is prohibited by default and design, with real technical blocks in place to enforce those policies.
- External oversight: the entire framework is audited by PRIVO, an FTC-approved COPPA Safe Harbor.
These safeguards do more than give buyers confidence that the inventory meets compliance requirements. They provide a specific, verifiable answer when someone asks how you know the inventory is high-quality, compliant, and appropriate for kids, rather than relying on a publisher or platform’s word alone.
Questions to Ask Before Buying Child-Directed Inventory
How is the inventory verified?
Look for a process that goes beyond publisher self-attestation and includes independent review against clearly defined criteria. Understanding who evaluates the inventory, how it is assessed, and how often it is reviewed can give buyers greater confidence in the supply path.
What safeguards reduce risk?
Ask which identifiers and data elements are permitted, restricted, or removed, and how those controls are enforced across the request and response. A transparent partner should be able to explain exactly how the bidstream is configured for child-directed media and describe a clear audit plan to confirm those configurations are working as intended over time.
How are responsibilities managed across the supply chain?
Every participant has a role to play, from the publisher and SSP to the DSP, agency, or brand. Look for clear contractual responsibilities, monitoring processes, and escalation procedures if an issue arises further down the chain.
How does the approach adapt as rules evolve?
Children’s privacy requirements, state laws, and platform policies will continue to change. Ask whether the underlying controls can accommodate new age thresholds and requirements without having to rebuild the entire media path.
What safeguards are in place to reduce risk?
Look beyond broad assurances and ask for specifics. The strongest partners should be able to explain which practices are technically blocked, how inventory and participants are reviewed, and what ongoing oversight supports those controls.
What compliance reporting is available?
For sensitive campaigns, specialized reporting can remove black boxes and offer real assurance. Responsible partners should be able to prove that the infrastructures they’ve built to support these campaigns are consistently working as intended.
Child-directed advertising was never going to be simple, and it shouldn’t be. Kids deserve heightened privacy protections, which is exactly why regulators watch this space so closely. But, kids also deserve access to quality content. That’s why we believe that building a programmatic path designed specifically for them — and the brands that want to reach them responsibly — is worth the effort.

Frequently asked questions
Question:What is the OpenX Child-Safe Marketplace?
The OpenX Child-Safe Marketplace is a curated programmatic path to child-directed CTV inventory. Publishers and buyers are individually approved and connected through private marketplace deals, personal data use is restricted and targeted advertising is blocked by design, and the framework is audited by PRIVO, an FTC-approved COPPA Safe Harbor.
Question: Is programmatic advertising to children allowed under COPPA?
Yes, within limits. COPPA and a growing set of state laws generally permit advertising on child-directed content when it is contextual and does not collect or use children’s personal data for targeting.
Question:Who verifies that the inventory is appropriate for children?
Inventory and participants in the Child-Safe Marketplace are reviewed against defined criteria rather than accepted on a publisher’s self-declared flag, and the whole framework is audited by PRIVO under the FTC’s COPPA Safe Harbor program.
Question:How do buyers access the Child-Safe Marketplace?
Buyers are approved individually and transact through private marketplace deals activated in their DSP. To start, contact BuyerDevelopment@openx.com or the OpenX team through the contact page.
