We spotted a targeted offer on the Platinum Card^® from American Express that could make adding an Additional Platinum Card a lot more rewarding.

Eligible cardholders can earn 20,000 Membership Rewards points after an Additional Platinum cardmember spends $2,000 in eligible purchases within the first 6 months — a nice return for anyone already considering adding a family member or partner to the account.

Here are the details.

Add an Additional Cardholder to the Amex Platinum Card and Earn 20K Points

We found a targeted Amex Offer on the Amex Platinum card that awards 20,000 Membership Rewards points after the first Additional Platinum cardholder spends $2,000 on eligible purchases within the first 6 months.

This offer applies only to the first cardmember added through the promotion. While American Express does not appear to impose a hard cap on the number of Additional Platinum cards you can add to your account, this bonus is limited to the first cardmember added with this offer.

Keep in mind that adding an Additional Platinum cardmember costs $195 per year (rates & fees), and as the primary cardholder, you’re responsible for any charges that person makes on the account.

Is It Worth It?

Yes — for many cardholders, this is a pretty solid deal.

At Upgraded Points, we value Amex Membership Rewards points at 2.2 cents each, so 20,000 points are worth about $440 by our estimation.

Since it costs $195 to add an Additional Platinum cardmember, you’re still coming out ahead by a pretty healthy margin if you were already considering adding a spouse, family member, or another trusted person to your account.

What also helps is that the spending requirement feels pretty manageable. Spending $2,000 in 6 months is not a huge lift for many households, especially if that additional card will be used for everyday purchases, travel, or a few larger planned expenses.

That said, this is really only a good move if you trust the person you’re adding. As the primary cardholder, you’re still responsible for whatever they charge. But if adding an Additional Platinum card was already on your radar, this offer definitely makes the decision easier.

Hot Tip:

This Amex Offer is valid for the first Additional Platinum cardmember you add and meets the $2,000 minimum spend requirement, so it’s best used for someone who’ll actually benefit from the card’s perks — and whose spending you fully trust.

Final Thoughts

If you were already thinking about adding an Additional Platinum cardmember to your Amex Platinum card, this offer is pretty much a slam dunk. Earning 20,000 Membership Rewards points after $2,000 in spend is a strong return, especially when we value those points at about $440.

Yes, there’s a $195 cost to add an additional cardmember, and yes, you’re still responsible for whatever that person spends. But if it’s someone you trust and were planning to add anyway, this is the kind of offer that can make the math work in your favor pretty easily.
