    Editorial take: Bilt Blue

    The no-fee entry tier of Bilt 2.0, launched February 7, 2026 by Cardless. Flat 1x earn (no bonus categories — those live on Obsidian and Palladium). Best for renters who want the no-fee anchor + full transfer partner access without paying $95+. The 5-transactions-per-cycle minimum from legacy Bilt is gone, and Rent Day still doubles everyday earn on the 1st.

    Editorial take: Amazon Business Prime American Express Card

    Common questions

    Which card has the bigger sign-up bonus, Bilt Blue or Amazon Business Prime American Express Card?
    The Amazon Business Prime American Express Card has the bigger bonus, $125 Amazon.com Gift Card, worth roughly $125, versus $100 Bilt Cash (~$100) on the Bilt Blue.
    Is the Bilt Blue's $0 annual fee worth it compared to the Amazon Business Prime American Express Card?
    The Bilt Blue has no annual fee, so the question is whether the Amazon Business Prime American Express Card's $0 fee is justified by its perks. If you'll use enough of the Amazon Business Prime American Express Card's benefits to clear $0 in value annually, it's worth it; otherwise stick with the Bilt Blue.
    Can I have both the Bilt Blue and Amazon Business Prime American Express Card?
    Yes, since they're from different issuers (Bilt / Cardless and American Express) the application rules don't conflict. Many points enthusiasts hold both, they pair well when one earns flexible bank points and the other earns a different currency.

    Get the one whose sign-up bonus you can hit comfortably without overspending. Bilt Blue: $0 spend in 0 months. Amazon Business Prime American Express Card: $0 in 0 months. Pick the easier minimum spend if you're new to points; pick the larger bonus if you have planned big purchases coming up.
