StackAdapt wants advertisers inside ChatGPT. A leaked pitch deck shows the demand-side platform pitching a limited pilot program with OpenAI. Shared with select buyers on March 27, the document outlines ad placements triggered by user prompts. CPMs start at $15 for narrow queries. They climb to $60 in competitive auctions. Minimum spend: $50,000 through May.
“StackAdapt has partnered with OpenAI to enable advertising within ChatGPT, one of the fastest growing consumer platforms in the world,” the deck states, as reported by Adweek.
The play targets users mid-research. Imagine typing “best running shoes for marathons.” An ad slips in, contextually matched. StackAdapt calls this a “discovery layer.” Early access. Discounted fees. But it’s proto. The system develops.
OpenAI confirms adjustments. Minimums now hover at $100,000 to $150,000, per sources cited in Adweek and a post by reporter Trishla Ostwal on X.
Yang Han sees potential. StackAdapt’s CTO told AdExchanger, “At any point in a conversation, ChatGPT can target a user with an ad at the right moment based on the content of their current chat.” Memory matters. ChatGPT recalls past queries. Suggest the right shoe size. Or model.
But challenges mount. Advertisers hesitate. No pixels. No attribution yet. Code in OpenAI’s “bazaar” ads manager hints at fixes. Internally code-named “tapestry,” it builds toward clicks and conversions, according to Adweek.
CPMs echo premium TV. $60 rivals NFL spots. Triple Meta’s rates. Criteo pitches similarly. Their deck to advertisers stresses compressed funnels. AI shopping in one chat. $60 CPM standard. Up to 50 products per campaign. Existing tags track referrals, as detailed by Digiday.
Agencies watch closely. Early promise. StackAdapt joins as DSP partner. Price cuts hit 75% in spots. Programmatic pipes open. But skepticism lingers among buyers, notes Ad Age.
Context rules. Han warns of a bind. “Becoming ‘fully contextually relevant’ will take time… Until ChatGPT has the same breadth of advertisers that, say, Meta has – and Meta works with millions – it risks ‘alienating users’ by showing mediocre ads.” Chicken-and-egg. Few advertisers mean weak ads. Weak ads chase users away.
Commercial intent low. Only 2-3% of queries buy-ready. Vs. Google’s 10-20%. Ads must intrude smartly. No banners in grief chats. Pharma skips sensitive topics. Ecommerce tempts CPG. Direct transactions. Model as middleman.
OpenAI expands beyond U.S. More buyers. Performance metrics incoming. Impressions today. Conversions tomorrow. Pilots test infrastructure. StackAdapt courts quietly. Leaks force transparency.
Users notice? Trust erodes if ads feel salesy. Ignored? Revenue dries. Advertisers test. Criteo integrates fast. No new contracts. StackAdapt auctions prompts. Niche wins cheap. Broad fights high.
Broader shifts. Code leaks confirm ads brewing. Android beta shows “search ad carousel.” Bazaar readies. OpenAI hires for growth platforms. ChatGPT monetizes. Conversations turn commercial.
StackAdapt positions sharp. Independent DSP. Early mover. But execution decides. Pilots end May. Data emerges. Buyers scale or bail. OpenAI iterates. Ads evolve from proto to powerhouse.
One fact clear. Prompts now inventory. Relevance bids highest. The chat window? Next frontier.
