American Express quietly updated its Membership Rewards terms this week. New cards no longer dump their points automatically into your existing pool. Instead, each fresh product gets its own separate rewards account by default.

The change, effective immediately as of mid-October 2026, applies to both personal and business cards opened from now on. Your existing cards and their current pooling setups remain grandfathered. No mass migration of old accounts, no sudden stranded balances on cards you already hold.

Why This Stings for Serious Players

Platinum holders who also run a Business Platinum, a Gold, a Blue Business Plus, and maybe a corporate card have enjoyed seamless flexibility. Points flowed freely, letting you hit transfer minimums or chase the best partner bonuses without thinking twice.

That convenience is now manual. Miss the step and a new card’s balance lives in its own silo. Cancel that card without linking first? Those points can vanish, even if you keep other Amex products open. The old safety net — one open MR-earning card preserves everything — no longer applies to unlinked new accounts.

It’s the kind of quiet policy tweak that feels designed to catch churners and multi-card optimizers. Amex isn’t saying why, but the timing after years of generous pooling suggests they’re tightening the screws on people treating the program like a points arbitrage machine.

Personal vs. Business, New vs. Existing

The split is clean: cards opened before the update keep their existing rewards account structure. New applications — whether a shiny Personal Platinum or a Business Gold — spawn a separate MR account tied to that product.

Business cards aren’t exempt. A new Blue Business Plus opened today will sit apart from your personal Gold until you connect them. Authorized users add another wrinkle. Points earned on an AU’s spending typically follow the primary account, but if the AU has their own linked product or you’re juggling household logins, the new siloed structure can create unexpected fragmentation. The 90-day AU rule for transferring to someone else’s loyalty accounts remains unchanged.

No announced deadline for grandfathered cards. Existing pools should stay linked unless you deliberately unlink them. Still, the writing is on the wall: future cards will all start isolated.

How to Manually Pool Points Now

It’s not complicated, but it’s one more thing to remember before you close a card or transfer to Singapore Airlines.

Log into the Amex website or mobile app. Navigate to Manage Connections. There you’ll see your separate rewards accounts and the option to link them. Select the ones you want consolidated. Points should merge, though it can take a few hours for the balance to update fully. Verify the combined total before moving points or canceling anything.

If the option doesn’t appear, call the number on the back of your card and ask the Membership Rewards team to link the accounts. Have your card numbers ready; reps can usually handle it quickly once they confirm you own everything.

Pro move: Do this the same day a new card posts. Set a calendar reminder. The few minutes saved now beats discovering 75,000 stranded points on a canceled Business Platinum six months from now.

The Edgy Reality Check

Amex built its premium reputation on flexibility. This feels like the beginning of a slow walk toward more restrictions — perhaps different transfer rules per account someday, or stricter limits on how many products can link to one pool.

For now, it’s manageable. But it adds friction exactly where power users hate it most: between earning and burning. Those who juggle half a dozen cards for category bonuses, employee cards, and transfer partner arbitrage just lost a layer of idiot-proofing.

The humor here is dark if you’re the type who’s canceled a card only to realize later the points never made it over. Amex support will probably be polite while explaining that, yes, those 120,000 points are gone because you didn’t click “Manage Connections.”

Don’t let that be you.

Action item: Log into every Amex account today. Check your rewards accounts under Manage Connections. Link every new or pending card immediately. Then review your upcoming applications and cancellations with fresh eyes. One extra step now keeps your points where they belong — ready to fly you to Tokyo in business class instead of disappearing into the ether.
