OpenAI shifted ChatGPT ads from CPM to cost-per-click pricing at $3-$5 per click, dropping the minimum spend from $250K to $50K.

⚡What happened

OpenAI switched ChatGPT ads to CPC pricing after CPM rates fell from $60 to $25 in 10 weeks.

→Why it matters

ChatGPT advertising is moving from experimental brand play to measurable performance channel, competing directly with Google and Meta.

🇦🇺AU angle

The $50K minimum still locks out most Australian SMBs, but mid-market and enterprise advertisers should be benchmarking CPCs now.

â—ŽWho cares

Paid media managers at mid-market and enterprise businesses evaluating emerging ad channels.

â–²Risk

Early movers will lock in lower CPCs before competition drives prices up, leaving latecomers paying premium rates.

Your move

Compare the $3-$5 CPC against your Google and Meta benchmarks to assess viability
