Six months ago, running a ChatGPT Ad meant a $200,000 cheque and an invite OpenAI wasn’t handing out to a roofer in Penrith. Today the minimum spend is zero and anyone with a card can launch one.
That’s the fastest a major ad platform has ever opened its doors. So here’s what it actually costs, no waffle.
As of May 2026, ChatGPT Ads in Australia run roughly $25 to $60 CPM (cost per thousand impressions), or $3 to $5 per click on CPC bidding. No minimum spend. You can start for the price of a small Google test.
That’s the headline. Now the part nobody else will tell you straight: the price has dropped through the floor, the clicks look cheap, and there’s a catch in the click-through rate you need to understand before you spend a dollar. I’ll get to it, because I’d rather you hear it from me than find out in month two.
ChatGPT Ads Cost at a Glance
| Pricing factor | Where it sits (May 2026) |
|---|---|
| CPM (cost per 1,000 impressions) | Roughly $25 to $60, down from a flat $60 at launch |
| CPC (cost per click) | $3 to $5 recommended starting bid |
| Minimum spend | None. Removed May 2026 |
| Bidding models | CPM (reach) and CPC (clicks) |
| Conversion tracking | Conversions API and pixel, live since May 2026 |
| Where you buy it | Self-serve Ads Manager at ads.openai.com, or through an agency |
| Who sees the ads | Logged-in Free and Go tier users. Plus, Pro, Business and Enterprise stay ad-free |
| Practical starting budget | $1,500 a month to gather enough data to optimise properly |
All figures in USD, which is how OpenAI prices the platform. Data as of May 2026, sourced from OpenAI’s Ads Manager and public reporting. This platform changes monthly, so I keep this page current.
How Much Does It Cost to Start ChatGPT Ads?
There is no minimum spend to start ChatGPT Ads as of May 2026. You can technically launch with any budget through the self-serve Ads Manager. Practically, I’d put at least $1,500 a month behind it. Below that you don’t gather enough clicks and conversions to optimise off, so you’re flying blind.
The “no minimum” thing is new and a big deal. At launch in February 2026, you needed a $200,000 to $250,000 commitment and an invite. That priced out every small and mid-sized business in the country. By May it was gone entirely.
So the door that used to be open only to Target and Ford is now open to a roofer in Penrith. That’s the bit worth paying attention to.
ChatGPT Ads CPM vs CPC: What’s the Difference?
ChatGPT Ads run on two pricing models, and which one you pick depends on what you’re chasing.
CPM (cost per thousand impressions) means you pay every time your ad is shown 1,000 times, clicks or no clicks. Think of it like renting a billboard. Good for awareness, getting your name in front of people researching your category. Sits around $25 to $60.
CPC (cost per click) means you only pay when someone actually clicks through. Like a cab meter that only runs when someone gets in. Recommended starting bids run $3 to $5. Better for leads and sales, because you’re paying for action, not eyeballs.
Here’s the bit most people miss: the auction is relevance-weighted and second-price. In plain English, a sharp ad on a modest bid beats a lazy ad on a fat budget. Good creative wins cheaper. Which is exactly the edge a bloke who actually writes the ads hands you, versus a set-and-forget agency that just throws money at it and hopes.
How ChatGPT Ads Pricing Has Changed in 2026
The platform has moved faster on price than anything I’ve seen. Here’s the actual timeline:
| Date | What changed |
|---|---|
| Feb 2026 | Launch. $60 CPM, $200,000 to $250,000 minimum spend, invite-only, CPM only |
| Mar 2026 | Rolled out to Australia. Still enterprise pricing |
| Apr 2026 | Minimum dropped to $50,000. CPC bidding introduced at $3 to $5. Self-serve beta begins |
| May 2026 | Minimum spend removed entirely. Self-serve opens up. Conversions API and pixel go live. CPMs observed as low as $25 |
In ten weeks the price of entry went from a quarter of a million dollars to nothing. That’s not a typo. Enterprise-only to anyone-with-a-card in a single quarter.
The takeaway is simple: entry has never been cheaper than it is today, and it won’t get cheaper from here. Every month more advertisers pile in, competition for placements climbs, and the cheap inventory dries up. The businesses getting in now lock in the cheap data and the learnings while everyone else is still asking whether it’s real. It’s not by fluke that early movers end up in front.
Is ChatGPT Ads Cheaper Than Google Ads or Meta?
On a straight cost-per-impression basis, here’s roughly where the three sit:
| Channel | Typical CPM | Typical CPC |
|---|---|---|
| ChatGPT Ads | $25 to $60 | $3 to $5 |
| Meta (Facebook/Instagram) | $10 to $25 | $0.50 to $3 |
| Google Search | Varies hugely | $2 to $50+ by industry |
So on paper, Meta’s cheaper per impression and Google Search can be cheaper per click in low-competition trades. If you only read that table, you’d skip ChatGPT and feel clever about it.
Don’t. The number that table hides is intent. Meta is serving your ad to someone thumbing through their feed at the traffic lights, half-watching. ChatGPT is serving your ad to someone who’s just typed out their entire problem in a paragraph and is sitting there waiting for an answer. One’s an interruption. The other’s an introduction at the exact moment they’re deciding. Same dollar, completely different value. Comparing the two on CPM alone is like picking a tradie on hourly rate and ignoring whether the job gets done.
The Catch Nobody’s Telling You: Click-Through Rates
Right, the bit I promised, and the bit most ChatGPT Ads pages quietly leave out.
ChatGPT Ads currently run a click-through rate around 0.91%. Google Search sits near 6.4%. So on average, roughly seven times fewer people click a ChatGPT ad than a Google search ad. There it is. No spin.
That sounds brutal, and if you walked in expecting Google numbers, you’d be filthy. But it’s the wrong comparison again. A ChatGPT click comes from someone who’s just described their problem in full, not someone tapping the first blue link out of habit. Early data from Criteo suggests AI referrals convert at about 1.5x other channels, though that’s their own retail data and not independently verified, so treat it as a hint, not gospel.
What it means in practice: ChatGPT Ads is a different shape of channel at an early stage. The clicks are fewer but warmer. Anyone promising you Google-level volume on day one is having you on. I’ll tell you straight whether your numbers stack up before you spend, not after.
What Does ChatGPT Ads Management Cost With an Agency?
There are two costs here and most agencies blur them together so you can’t tell what you’re actually paying for. I won’t.
Cost one is your ad spend. That’s the money that goes to OpenAI. The $1,500 a month and up I mentioned. That’s not mine, I never touch it, it’s yours.
Cost two is management. That’s what you pay someone to actually run the thing: build the campaigns, write creative that works in a conversation instead of recycled Google copy, wire up conversion tracking, then read the data and optimise off it every week.
No contracts. No lock-in. No retainer with a vague scope designed so you can never quite tell what you’re getting.
You tell me what you’re running and what you’re chasing, I give you a straight number. If ChatGPT Ads aren’t right for you yet, I’ll tell you that too and save us both the hassle. This is the benefit of having a ChatGPT Ad specialist working for you.
Say G’day and let’s sort it.
Frequently Asked Questions
How much do ChatGPT Ads cost in Australia?
As of May 2026, ChatGPT Ads cost roughly $25 to $60 CPM, or $3 to $5 per click on CPC bidding. There’s no minimum spend. Practically, start with at least $1,500 a month so there’s enough data to optimise the campaign properly.
Is there a minimum spend for ChatGPT Ads?
No. OpenAI removed the minimum spend entirely in May 2026 when the self-serve Ads Manager opened up. At launch in February it required a $200,000 to $250,000 commitment, but that’s gone. You can now start with a small test budget.
How much should a small business budget for ChatGPT Ads?
Start with at least $1,500 a month. There’s no minimum spend, so you can technically go lower, but below roughly $1,500 you won’t gather enough clicks and conversions to optimise off. High-value industries like dental, finance, roofing and legal usually need more to compete.
Are ChatGPT Ads cheaper than Google Ads?
It depends what you measure. Google Search clicks can be cheaper in low-competition trades, but pricier than $5 in finance and legal. ChatGPT CPMs sit around $25 to $60. The real difference isn’t price, it’s intent: ChatGPT clicks come from people deep in a research conversation, not a passive search.
What is the CPC for ChatGPT Ads?
OpenAI’s recommended starting CPC bid for ChatGPT Ads is $3 to $5 per click as of May 2026. The auction is relevance-weighted and second-price, so a well-written ad on a lower bid can beat a weak ad on a higher one. Bids under $3 often fail to deliver impressions.
Do you need to pay an agency to run ChatGPT Ads?
No. The self-serve Ads Manager at ads.openai.com lets any business run them directly. But running them well, writing conversational creative, setting up conversion tracking and optimising off the data, is where most DIY campaigns fall down. An agency cost is separate from your ad spend.
How much is ChatGPT Ads CPM compared to launch?
ChatGPT Ads CPM has dropped from a flat $60 at the February 2026 launch to roughly $25 to $60 by May 2026, depending on category. The minimum spend fell from $200,000 to zero over the same period. Entry costs are the lowest they’ve been.
Why is the ChatGPT Ads click-through rate so low?
ChatGPT Ads run a CTR around 0.91%, about seven times below Google Search’s 6.4%. It’s a younger channel with fewer, warmer clicks. People click less often, but those who do have usually described their full situation first, so the intent behind each click is higher.
Want a Straight Answer on What It’ll Cost You?
Ad spend is one number. Whether ChatGPT Ads make sense for your business is another. I’ll give you both, honestly, before you spend a dollar.
If the numbers don’t stack up for you, I’ll say so. If they do, I’ll have it running properly from day one.
Say G’day here and let’s work it out.
No contracts. No middlemen. No fluff.
