The automated ad product that alpha-tested with 600+ brands is now available to everyone, with third-party API support and a way to run multiple creative sets in one campaign.

On September 3, 2026, Reddit made its AI-powered Max campaigns available to all advertisers on the platform. Max is Reddit's automated buying product: an advertiser supplies creative assets, a budget, and a goal, and Reddit's system handles targeting, creative selection, ad placements, and budget allocation, adjusting bids and placements in real time as it learns what performs. Reddit first launched Max in beta the week of January 5, 2026, after alpha-testing it with more than 600 advertisers across different verticals and business sizes.
Alongside the general rollout, Reddit announced two additions. Its ads API now supports Max, so advertisers can create and manage campaigns through third-party tools — the ad-automation platform Smartly is the first integration. And a new "asset groups" feature lets a single Max campaign hold multiple sets of creative, each representing a different product line or use case (Reddit's example: running shoes, training apparel, fitness accessories) with its own headlines, media, and destination URL.
Reddit says alpha testers running Max saw, on average, about 17% lower cost per acquisition and more than 27% additional conversions across split tests, and it cited a Brooks Running test that saw a 37% lower cost-per-click and 27% more clicks over 21 days with no manual adjustments. The system draws on Reddit's Community Intelligence — signals from more than 23 billion posts and comments — to cluster audiences into interest-based segments. Treat the performance figures as company-reported results from selected campaigns rather than independently audited benchmarks, and confirm current capabilities in Reddit's ads help center before planning spend.
Max automates the media buying, but it still runs on creative you have to supply — and its new asset-groups feature specifically wants several distinct creative sets, one per product line or use case, each with its own headlines, media, and destination. That is a production problem, and it is exactly what [Kompozy](/) is built to solve. Kompozy is a content generation and multi-platform publishing engine: from one brief or source it produces the on-brand set an asset group needs — [Photo Posts](/glossary/hyperframes), [Listicle Video](/ai-tools), carousels, and short-form video — governed by a written [Persona Brief](/glossary/persona-brief) so every variant stays in voice, and rendered with [HyperFrames](/glossary/hyperframes) for pixel-exact brand styling. Instead of hand-building three creative sets for running shoes, apparel, and accessories, you generate the matrix and hand Max more to test.
The other half is the organic presence that makes paid reach land. Reddit is a Direct Connect publishing destination in Kompozy (via Bundle.social), alongside the eight primary social platforms plus blog and email — so the same content library that feeds your Max asset groups also ships as native posts to your subreddit presence and everywhere else, on a schedule, behind a per-post review gate.

Max is Reddit's AI-powered, automated advertising product. You provide creative assets, a budget, and a goal, and Reddit's system handles targeting, creative selection, ad placements, and budget allocation, then adjusts bids and placements in real time based on performance and its Community Intelligence signals. It launched in beta in January 2026 and opened to all advertisers on September 3, 2026.
Asset groups let a single Max campaign contain multiple sets of creative, each representing a different product line or use case — Reddit's example is running shoes, training apparel, and fitness accessories. Each group has its own headlines, media, and destination URL, so one campaign can advertise several offers while the system optimizes across them.
Yes. With the September 2026 rollout, Reddit's ads API supports Max campaigns, so advertisers can create and manage them via third-party platforms. The ad-automation tool Smartly was announced as the first integration, with the API opening Max to other partners over time.
Reddit reports that alpha testers saw, on average, about 17% lower cost per acquisition and more than 27% additional conversions across split tests, and cited a Brooks Running test with a 37% lower cost-per-click and 27% more clicks over 21 days. These are company-reported figures from selected campaigns, so treat them as directional and validate against your own results.
