American Express added a benefit that no other issuer offers right now: an Amex ChatGPT credit worth up to $300 in statement credits per calendar year. It applies to The Business Platinum Card® from American Express and the American Express® Business Gold Card. You have to enroll first, and the purchase has to go directly to OpenAI in the United States.
However, $300 does not quite cover a year of ChatGPT Business at list price. The gap is small, and the way you set up your billing decides whether you pay $180, $300, or nothing at all. Below, we break down the pricing math, the two setups that bring your cost to zero, and the mistakes that void the credit. For the wider picture on which cards earn their fees, see our guide to the best credit cards in the U.S.
The benefit reimburses your ChatGPT Business subscription up to $300 each calendar year. Importantly, the clock runs from January 1 to December 31, not from your card anniversary or your annual fee date. Amex pays the credit against the first $300 of eligible charges you post in that window, so there is no monthly cap to work around.
ChatGPT Business requires a minimum of two seats. OpenAI cut the price in April 2026, so the plan now runs $20 per seat per month with annual billing, or $25 per seat per month with monthly billing. Consequently, the smallest possible subscription costs either $480 or $600 a year depending on how you pay.
At first glance, annual billing wins: $480 beats $600. Nevertheless, that comparison ignores how the statement credit actually works. The billing choice matters more than the sticker price, as the next section shows.
Annual billing produces a single $480 charge on a single day. Therefore, that charge can only ever touch one card’s $300 credit. You get $300 back and pay $180 out of pocket, and the second credit sits unused if you hold both cards.
Monthly billing splits the same subscription into twelve $50 charges. Because those charges land on different dates, you can move them between cards and between calendar years. In other words, monthly billing costs $120 more in list price but gives you access to $300 more in credits. That trade is worth $180 a year.
If you already carry both the Business Platinum and the Business Gold, this is the cleanest setup. Each enrolled card account carries its own $300 credit, so two cards give you $600 of coverage per calendar year. Meanwhile, two seats on monthly billing cost exactly $600 a year. The numbers match to the dollar.
Open your OpenAI billing settings around July 1 and replace the card on file. The switch takes a minute and does not interrupt the subscription. Afterward, check the credit tracker in your Amex Benefits Dashboard: it shows exactly how much of the $300 remains on each card, so you can confirm the first credit fully cleared before the second one starts working.
Only hold one of the two cards? You can still get twelve consecutive months for free by starting the subscription in July on monthly billing. Six months of charges at $50 use up this year’s $300 credit. Then the credit resets on January 1, and the next six months of charges use the fresh $300.
Be clear about what happens next, though. From July of the second year onward, the credit for that year is already gone, so you pay full price for the rest of the calendar year. In short, the straddle buys you one free year rather than a permanent arrangement. After that, a single card covers half of a $600 monthly-billed plan, or 62.5% of a $480 annual plan.
Here is how the four realistic combinations compare over a full calendar year, assuming the two-seat minimum. Notably, the setup most people default to, one card on annual billing, is not the cheapest one available.
The math holds only at two seats. For instance, a three-seat plan on monthly billing costs $900 a year, so even two credits leave $300 uncovered. Before adding a seat, ask whether the extra person genuinely needs one.
The Amex ChatGPT credit is straightforward on its own: enroll, pay OpenAI, get up to $300 back per calendar year. The interesting part is the billing choice. Annual billing looks cheaper and leaves you $180 short, while monthly billing costs more on paper and can bring you to zero.
If you hold both the Business Platinum and the Business Gold, switch the card on file at OpenAI around July 1 and two seats cost you nothing, year after year. If you hold one card, start the subscription in July and ride two calendar-year credits back to back for twelve free months. Either way, keep the plan at two seats and check the Benefits Dashboard tracker before you make the switch.
Neither card is worth carrying for this benefit alone. Both earn Membership Rewards points and carry their own travel and business perks, so weigh the full package against our roundup of the best business credit cards and the wider best American Express credit cards before you apply.
