ChatGPT Ads: Daily Caps Replaced by Weekly Averages

OpenAI is changing how ChatGPT Ads Manager handles daily spending limits. Instead of a fixed daily cap, budgets will now operate as a seven-day average. This means your daily spend may vary, but it will average out over a week. The change applies automatically to existing campaigns. There is no option to revert to the previous fixed daily limit. What's interesting is that while a seven-day limit is clear, there is no specified ceiling for how much a campaign can overspend on a single day. This update was part of a larger announcement that included new features like conversion-optimized bidding and geographic exclusions. Automatic intraday pacing is also being introduced to distribute spending more evenly throughout the day. The bottom line is that advertisers need to be aware that their daily ad spend can now fluctuate significantly.
