Bilt Palladium + Obsidian: The Ultimate Two-Player Credit Card Strategy
The strongest Bilt setup for a couple is one Bilt Palladium Card and one Bilt Obsidian Card. Player one uses Palladium for 2X on everyday spending and pays the rent or mortgage through it. Player two sets Obsidian to 3X on groceries. Combined annual fees are $590.
This post is the how-to. My Bilt Palladium review explains why I rate the card so highly. If you apply, here is my Bilt referral link. I earn a referral bonus from Bilt if you are approved, at no cost to you.
The short version
Bilt allows one Bilt card per member, so holding both cards takes two people.
Palladium is the household default at 2X. Obsidian takes groceries at 3X, up to $25,000 a year.
Put the housing payment on the Palladium account, since most card spending lands there.
On a $5,000 mortgage with $3,500 of monthly Palladium spending, Flexible Bilt Cash earns 4,666 housing points a month. Housing-only earns 3,750.
The two cards carry $500 in Bilt Travel hotel credits and $200 in Bilt Cash a year.
Bilt Points do not pool between two members, so plan who earns what.
How does the two-player Bilt setup work?
A two-player Bilt setup gives each card one job. The Bilt Palladium Card earns 2X on everyday purchases, so it takes every purchase with no better home. The Bilt Obsidian Card earns 3X on dining or groceries and 1X on general purchases, so it takes only its bonus category. One person cannot hold both. Bilt's program overview says: "Each member can only have one Bilt Card at a time."
Purchase | Card | Rate |
|---|---|---|
Groceries | Obsidian | 3X, up to $25,000 a year |
Everyday and large purchases | Palladium | 2X |
Other travel | Palladium | 2X on both cards |
Hotels through Bilt Travel | Either | 4X, and each card has its own hotel credit |
Flights through Bilt Travel | Either | 3X |
Lyft | Palladium | 4X, against 3X on Obsidian |
Bilt partner restaurants | Check the app | Up to 5X on Palladium, up to 6X on Obsidian |
Rent or mortgage | Palladium account, through Bilt | Up to 1.25X |
Dining | Your best dining card | Varies |
Costco warehouse | A Visa card | Bilt cards are Mastercards |
Never put ordinary 1X spending on Obsidian. The same purchase earns 2X on Palladium.
Bilt lets you add authorized users, and rewards from their spending go to the primary account by default. An authorized-user Palladium card in player two's wallet keeps general purchases at 2X.
An authorized user costs $95 a year on Palladium, $50 on Obsidian and $0 on Blue. The Palladium authorized-user card earns one more point per dollar than Obsidian's 1X on general purchases. At $9,500 a year of player two's general spending, the $95 fee buys 9,500 extra points, or 1 cent each. Below $9,500, skip it and let player one make those purchases.
Which Obsidian category should player two pick?
The Bilt Obsidian Card pays 3X on dining or groceries, and I would pick groceries in most households. Plenty of cards pay 3X or 4X at restaurants. Fewer pay a bonus at the supermarket. The grocery bonus stops at $25,000 a year, and purchases past the cap earn 1X. Dining has no cap.
Timing matters. Bilt's Obsidian page says: "At account opening, dining is your default 3X category." You have 30 days to switch to groceries in the Bilt app. After those 30 days, you change the category once a year, in January.
With groceries on Obsidian, dining stays open for whichever card pays you most. Check the Bilt app before you book a table. Bilt lists 20,000+ partner restaurants, paying up to 5X on Palladium and up to 6X on Obsidian.
Which player should pay the rent or mortgage?
Player one should pay the housing bill through the Bilt Palladium account. Bilt's Housing-only option sets your rate by comparing one card's everyday spending with the housing payment in the same billing cycle. Splitting spending across two cards lowers the ratio on both. Palladium carries most of the household's spending, so the payment belongs there. The four tiers are in my Palladium review.
Take a household with a $5,000 mortgage and monthly spending of $1,500 on groceries, $1,000 on dining, $1,000 on travel and $3,500 on everything else.
Groceries go on Obsidian. If only the $3,500 of general spending goes on Palladium, the ratio is 70% and the mortgage earns 0.75X. Move the $1,000 of travel to Palladium, which costs nothing since both cards earn 2X on it. The ratio reaches 90%, and the mortgage earns 1X.
Bilt's second option, Flexible Bilt Cash, pays 4% in Bilt Cash on card spending. Every $30 of Bilt Cash earns 1,000 housing points, up to 1X. For this household, the two options compare like this each month:
Monthly Palladium spending | Housing-only | Flexible Bilt Cash |
|---|---|---|
$3,500 | 3,750 points (0.75X) | 4,666 points, $0 left |
$4,500 | 5,000 points (1X) | 5,000 points, $30 left |
$5,000 | 6,250 points (1.25X) | 5,000 points, $50 left |
Housing-only wins once Palladium spending matches the housing payment. Below it, Flexible Bilt Cash matches or beats Housing-only in this example. Run your own numbers near the 25% and 50% thresholds, where Housing-only pulls ahead. A change of option takes effect in the following billing cycle, so choose for your typical month.
Player two has no housing payment on Obsidian, so Housing-only pays the Obsidian account nothing. Set Obsidian to Flexible Bilt Cash. $1,500 a month of groceries earns $60 of Bilt Cash, or $720 a year.
Should you chase the 1.25X housing tier?
Chase the 1.25X Bilt housing tier only when the points you gain exceed the points you give up. In the example household, reaching 100% takes another $500 a month on the Bilt Palladium Card, and the only spending left is dining.
The jump from 1X to 1.25X adds 1,250 points a month. $500 of dining earns 1,000 points on Palladium at 2X, and a 4X dining card would have paid 2,000. The net gain is 250 points a month. Against a 3X dining card, the gain is 750.
The reverse case fails. Moving $1,000 from a 5X card to Palladium gives up 3,000 points, and no tier jump on a $5,000 payment pays more than 1,250.
Where should the Point Accelerator go?
The Bilt Point Accelerator costs $200 of Bilt Cash and adds 1X on the next $5,000 of everyday spending, up to five times a year. It requires the Flexible Bilt Cash option. With it, the Bilt Palladium Card earns 3X on everyday spending. The Bilt Obsidian Card earns 4X on its dining or grocery category, 3X on travel and 2X elsewhere.
Each player earns and spends their own Bilt Cash. Player two's $720 funds three activations for $600. Those cover $15,000 of groceries at 4X and add 15,000 points a year.
Player one fills the housing redemption first. My review shows the math: housing costs 3 cents of Bilt Cash per point, and the accelerator costs 4 cents. Palladium's $200 of annual Bilt Cash covers one activation.
The accelerator works on the primary card only. An authorized-user card keeps its normal rate while an activation runs, so player one makes the accelerated purchases on their own Palladium.
Activate before a stretch of planned spending: a renovation, furniture, appliances, holiday shopping or dental work. Each activation ends at $5,000 or at year end. Rent and mortgage payments do not count as everyday spending. Bilt's terms exclude other transaction types too, so read them before you count on tuition, insurance or a tax bill.
Do the credits cover $590 in annual fees?
The Bilt Palladium Card at $495 and the Bilt Obsidian Card at $95 cost $590 a year together. They return $500 in Bilt Travel hotel credits and $200 of Bilt Cash, or $700 in nominal credits.
Palladium's $400 comes as two $200 credits. Obsidian's $100 comes as two $50 credits, one for January through June and one for July through December. Every credit needs a Bilt Travel hotel booking of two nights or more.
Count the credits at face value only if you would book those stays anyway. Plan one two-night stay in each half of the year on each card. The January to June credit does not carry into July.
When does another card beat Bilt?
The Bilt Palladium Card and Bilt Obsidian Card should not take every purchase. Use another card when it clearly pays more:
A 5X category on another card beats 2X on Palladium.
A welcome bonus. $6,000 of spending toward a 100,000-point bonus returns about 16 points per dollar.
A merchant offer. 10% back from an Amex Offer or a Chase Offer is worth more than the gap between 2X and 3X.
Hotel and airline cards, when you need free checked bags, elite credit or on-property earning.
Costco. U.S. Costco warehouses take Visa, and Bilt cards are Mastercards. Keep one Visa for Costco.
Complicated airfare. Bilt Travel pays 3X on flights, but I book direct when the trip is international or a schedule change is likely, so the airline controls the ticket.
Do Bilt Points pool between two players?
Bilt Points do not pool between two members. Bilt does not combine points across accounts, and transfers go to loyalty accounts in your own name, according to Upgraded Points. Each player keeps a separate balance.
In this setup, player one earns most of the points, so book the big awards from player one's account.
Several Bilt partners let two members combine points after the transfer. World of Hyatt and Hilton Honors pool points between members. United MileagePlus, British Airways Avios and Air France-KLM Flying Blue pool between family or household members. Atmos Rewards shares points free for Atmos Rewards Summit cardholders and charges other members a fee. Each player transfers Bilt Points to their own account in one of those programs, then combines them there.
Keep points in Bilt until you have found the award and confirmed the seats or rooms. Bilt's transfer page says: "Once points are transferred, they cannot be reversed." The 25 partners are listed in the review.
How many points does the example household earn?
The example household earns 222,000 Bilt Points a year from the Bilt Palladium Card and the Bilt Obsidian Card before dining:
Groceries on Obsidian: $18,000 at 3X is 54,000 points
General spending on Palladium: $42,000 at 2X is 84,000 points
Travel on Palladium: $12,000 at 2X is 24,000 points
The $60,000 of mortgage payments at 1X is 60,000 points
Player one's account receives 168,000 of those points and player two's receives 54,000. Accelerators, Bilt partner restaurants, Rent Day transfer bonuses and both welcome offers come on top.
The Bottom Line
Palladium is the household default. Obsidian takes groceries. The housing payment goes on the Palladium account, and your choice of housing option depends on whether Palladium spending reaches the payment. Player two runs Flexible Bilt Cash and spends it on accelerators. Any card paying clearly more than Bilt gets the purchase.

FAQ
Can one person hold both the Bilt Palladium and Bilt Obsidian cards?
No. Bilt allows one Bilt card per member at a time. Pairing the Bilt Palladium Card with the Bilt Obsidian Card takes two people, each with their own Bilt account and their own points balance.
Which Bilt card should pay the mortgage in a two-player setup?
The Bilt Palladium account should pay the rent or mortgage. Bilt's Housing-only rate depends on one card's everyday spending measured against the housing payment, and Palladium carries most of a household's spending at 2X.
Is Housing-only or Flexible Bilt Cash better?
Housing-only is better when your Bilt card spending matches or exceeds your housing payment, since it pays 1.25X. Flexible Bilt Cash stops at 1X but earns about 1.33 housing points per dollar of card spending, which often wins below 100%.
When do you choose the Bilt Obsidian 3X category?
The Bilt Obsidian Card defaults to 3X on dining at account opening. You have 30 days to switch to groceries in the Bilt app. After those 30 days, you change the category once a year, in January.
Do Bilt cards work at Costco?
Bilt cards are Mastercards, and U.S. Costco warehouses accept Visa credit cards only. Keep a Visa card for Costco warehouse purchases.
Earning rates, Bilt Cash rules, transfer partners and card benefits change. Verify current terms with Bilt before applying. Fact-checked against Bilt's card and support pages on September 20, 2026. This strategy assumes you pay your balances in full.
