The biggest credit card issuers by volume
The largest credit card companies in the United States are Chase, Bank of America, Citigroup, American Express, and Discover. These five issuers control the majority of cards in circulation and set many of the terms that smaller banks follow. Chase alone issues roughly one in four credit cards used in the country.
Size matters because larger issuers have more resources to build rewards programs, negotiate merchant fees, and absorb fraud losses. They also tend to have more card options within their portfolios, so you are more likely to find a product that matches your spending pattern. However, size does not may provide the best terms for you — a smaller regional bank or credit union may offer a card with lower fees or higher rewards in a category you use frequently.
The companies listed here are issuers, meaning they own the credit line and decide who gets approved and on what terms. They are different from the card networks — Visa, Mastercard, American Express, and Discover — which process transactions and set interchange rules. A card can carry the Visa logo but be issued by Chase, Bank of America, or dozens of other banks.
Key Takeaways
- Chase, Bank of America, Citigroup, American Express, and Discover issue the majority of credit cards in the United States and offer the widest range of rewards and benefits.
- Larger issuers typically have more card options, stronger fraud protection, and more established rewards programs, but their terms are not automatically better than smaller competitors.
- Each major issuer has a different rewards structure and fee schedule, so comparing cards across issuers is necessary to find the best match for your spending.
- Smaller banks and credit unions sometimes offer cards with lower annual fees or higher rewards in specific categories, even if their overall product selection is narrower.
Chase: The largest issuer by market share
Chase issues roughly 90 million credit cards and operates under the JPMorgan Chase brand. Its portfolio includes the Sapphire line (premium travel and dining rewards), the Freedom line (rotating category bonuses), the Ink line (business cards), and co-branded cards with United Airlines, Amazon, and other partners.
Chase cards tend to have higher annual fees on premium products but offer rewards rates that scale with spending. The Sapphire Preferred and Sapphire Reserve, for example, charge $95 and $550 per year respectively but offer point multipliers on travel and dining. Chase also owns the largest network of branch locations of any bank, which can matter if you need in-person service.
Chase's approval standards are generally stricter than smaller issuers — the company typically prefers applicants with credit scores above 700 and established credit history. If you are denied, Chase allows you to reapply after 30 days, and the company publishes its approval rates by card product on its website.
Bank of America: Broad card selection and tiered rewards
Bank of America issues roughly 50 million cards and offers products across every major category: cash back, travel, student, and business. Its Cash Rewards card has no annual fee and offers 1% cash back on all purchases, making it a baseline option for people who want simplicity without rewards complexity.
Bank of America's premium cards — the Premium Rewards and the Alaska Airlines card — use a tiered rewards structure where your cash back or points rate increases based on your account balance with the bank. A customer with $100,000 in deposits may earn 2.625% cash back on all purchases, while someone with less may earn 1.5%. This structure rewards loyalty to the bank as a whole, not just card spending.
Bank of America also owns Merrill Lynch and offers investment-linked rewards through its Preferred Rewards program. If you have a brokerage account or retirement account with Merrill, you can boost your card rewards by up to 75%, which can be valuable if you are already investing with the company.
Citigroup: Rewards flexibility and international options
Citigroup issues roughly 50 million cards under the Citi brand and specializes in flexible rewards that let you move points between partners. The Citi Prestige and Citi Premier cards offer points that can be transferred to airline and hotel partners at a 1:1 ratio, or redeemed for cash back at a lower rate.
Citi's strength is in travel rewards and international benefits. Several Citi cards offer trip delay reimbursement, baggage protection, and concierge services that appeal to frequent travelers. Citi also has a large network of partner airlines and hotels, so your points have more redemption options than some competitors.
Citi's approval process is moderately strict, and the company tends to offer lower credit limits to new customers than Chase does. However, Citi is known for being willing to work with people who have fair credit (scores in the 650–700 range) if they have a good payment history.
American Express: Premium positioning and membership benefits
American Express issues roughly 60 million cards and operates differently from Visa and Mastercard issuers. Amex cards are not accepted everywhere — roughly 99% of U.S. merchants accept Visa or Mastercard, but only about 70% accept American Express. This limits Amex's usefulness as an everyday card for some people, but it also means Amex can charge higher fees and offer more generous benefits because cardholders are less price-sensitive.
Amex's premium cards — the Platinum Card and the Centurion Card (the "black card") — charge annual fees of $695 and $10,000 respectively but offer benefits like airport lounge access, concierge services, and statement credits for specific purchases. These cards are designed for high-income people who spend heavily on travel and dining and value service over rewards rates.
Amex also issues the Blue line of cards, which offer cash back without annual fees and are positioned as everyday cards. The Blue Business Plus offers 2% cash back on the first $50,000 in purchases each year, then 1% after that, making it useful for small business owners with moderate spending.
Discover: Lower fees and strong fraud protection
Discover issues roughly 30 million cards and positions itself as a lower-cost alternative to the major issuers. Discover cards typically have no annual fees, and Discover's cash back rates are competitive — the Discover It card offers 5% cash back in rotating categories (capped at $1,500 per quarter) and 1% on everything else.
Discover's main limitation is acceptance. Because Discover is both a network and an issuer, it has less merchant coverage than Visa or Mastercard. Roughly 99% of U.S. merchants accept Visa or Mastercard, but only about 95% accept Discover. This gap matters most at small retailers, gas stations, and international merchants.
Discover is known for approving applicants with fair credit and for offering credit-building features like free credit score monitoring and automatic credit limit increases. If you are rebuilding credit, Discover cards are often easier to get approved for than Chase or Bank of America products.
How to compare cards across issuers
The best card for you depends on where you spend money, how much you spend, and what benefits matter to you. A person who spends $3,000 per month on dining and travel should compare the Sapphire Preferred (Chase), the Citi Premier, and the Amex Gold — all three offer 3x or 4x points on those categories. Someone who spends $1,000 per month on groceries and gas should compare the Discover It, the Bank of America Cash Rewards, and the Citi Double Cash, which offer higher rates in those categories.
Annual fees are a real cost, not a marketing expense. A card with a $95 annual fee needs to deliver at least $95 in value through rewards, credits, or benefits to break even. If you spend $500 per month on dining and a card offers 3x points worth 1 cent each, you earn $18 per year in rewards — not enough to justify a $95 fee.
Approval odds vary by issuer and by card. Chase and American Express are stricter than Discover and Bank of America. If your credit score is below 700, you may be denied by Chase but approved by Discover. Check the issuer's published approval criteria before you explore, because multiple applications in a short time can lower your credit score.
Frequently Asked Questions
Which credit card company is the safest?
All five major issuers are FDIC-insured banks or subsidiaries of FDIC-insured banks, so your account is protected up to $250,000 if the bank fails. All five also offer fraud protection and zero-liability policies for unauthorized charges. Safety is not a meaningful differentiator — the real difference is customer service speed and how willing they are to reverse disputed charges.
Can I get a credit card from a smaller bank instead of these five?
Yes. Regional banks, credit unions, and online-only banks issue credit cards with competitive terms. A credit union card might have a lower annual fee or higher rewards in a specific category. The trade-off is usually fewer card options and less robust online tools. If you have a relationship with a smaller bank or credit union, ask what cards they issue before you explore to a major issuer.
Do I need to have a bank account with an issuer to get their card?
No. You can explore for a Chase card without having a Chase checking account, a Bank of America card without a Bank of America account, and so on. However, some issuers offer small bonuses (like $50 cash back) if you open a checking account at the same time, so it is worth checking whether that incentive applies to the card you want.
What happens if I get denied by one of these issuers?
You can reapply after 30 days. Most issuers will tell you the reason for denial — usually insufficient credit history, too many recent applications, or a credit score below their minimum. If the reason is a credit report error, you can dispute it with the credit bureau and reapply once it is corrected. If the reason is a low score, waiting three to six months and building credit history will improve your odds.
Are rewards points worth the same across issuers?
No. Chase points are worth roughly 1 cent each when redeemed for cash back, but 1.5 cents when transferred to airline partners. Amex points vary by card and redemption method. Citi points are worth roughly 1 cent for cash back. Discover cash back is literal cash. Compare the redemption value of each issuer's points before you choose a card based on rewards alone.
