The credit-card sign-up bonus is a real source of return on consumer time, and it has remained a real source of return through the various restrictions issuers have imposed over the last several years. The rules have gotten more complex; the bonuses have gotten more conditional; the cool-off periods have lengthened. The basic shape of the activity — apply for a card, meet a minimum spend, receive a bonus, hold the card for an appropriate period, repeat — is still operational.

This piece is a working guide to the rules that actually matter for anyone considering credit-card optimization in 2026.

The basic shape of a sign-up bonus

A credit-card sign-up bonus pays the new cardholder a quantity of points, miles, or cash for spending a defined amount on the card within a defined time. A typical 2026 offer on a premium travel card might be: “100,000 points after spending $5,000 in the first three months.” The card may also include a first-year annual-fee waiver or a smaller statement credit.

For an organized user whose normal monthly spending easily exceeds the minimum spend, the bonus represents nearly pure return on the time invested in applying for the card and managing the account. For a user who has to manufacture spending — pay for things they would not otherwise buy in order to hit the threshold — the bonus quickly becomes worth less than the manufactured spending.

The headline value of a bonus depends on the redemption efficiency of the program. Points in flexible-currency programs (Chase Ultimate Rewards, Amex Membership Rewards, Capital One miles, Citi ThankYou Points) are typically worth 1.0 to 1.8 cents each at smart redemptions. Hotel-specific points are often worth less; airline-specific points worth more or less depending on the airline and the redemption.

The major rules to know

Chase’s 5/24 rule. Chase will generally decline credit-card applications from any customer who has opened five or more new credit-card accounts (from any issuer) in the trailing 24 months. The rule is enforced consistently and applies to most Chase consumer cards. Business cards from most issuers (excluding Capital One and a few others) do not count toward the 5/24 number. This rule structures sequence: most card optimizers prioritize Chase cards before reaching their 5/24 limit.

Amex once-per-lifetime restriction. American Express applies a lifetime restriction on bonuses on most of its consumer cards. If you have previously held the Platinum card and received a bonus on it, you typically cannot receive a bonus on it again. Amex occasionally extends offers to long-tenured customers, but these cannot be relied on. Plan card sequence to take Amex bonuses on cards you have not previously held.

Capital One application restrictions. Capital One has tightened restrictions over the last two years. The current rule for personal Capital One cards is approximately one new card every six months, with stricter limits on customers who have had multiple Capital One cards. Capital One business cards count toward Chase’s 5/24 number, unlike most other issuers’ business cards.

Citi 24-and-48-month rules. Citi’s restrictions vary by product family. The American Airlines AAdvantage cards have a 48-month restriction (no bonus if you have had any AAdvantage card in the prior 48 months). Other Citi cards have a 24-month restriction. The product-family detail is sometimes specified in the offer terms; read them.

Bank of America’s restrictions. Bank of America has tightened on cardholders with multiple recent BoA cards over the last several years. Customers with three or more BoA cards opened in the last 12 months, or seven or more in the last 24 months, are commonly declined.

These five rules collectively cover most of what an organized churner needs to know in 2026. The detailed restrictions on a specific card should always be checked at the time of application, but these five categorical rules tend to be stable.

What the restrictions don’t cover

Several common consumer beliefs about churning are not actually restrictions, or are softer than commonly stated:

Annual-fee waivers being rare. The first-year annual fee on premium cards is increasingly waived as part of the bonus offer, sometimes silently. Read the offer terms.

“Don’t churn, banks track everything” — overstated. Banks track applications and account openings, but they do not generally maintain shared databases of “churners” across institutions in the way some online forums suggest. Each issuer enforces its own rules; cross-issuer surveillance is limited.

“Closing a card hurts your credit” — overstated. Closing a card eliminates the available credit on that card and shortens your credit history slowly over time, but the effects are smaller than the popular framing implies. For a user with multiple long-tenured credit accounts, closing a single recent card has a modest effect.

Common ways people get stuck

The mistakes that lock otherwise-sensible people out of cards or out of bonuses are usually one of:

Applying for too many cards in a short window. Issuers see the recent applications on your credit report and decline. Spreading applications over months, with one or two per quarter, is the safer pattern.

Failing to meet the minimum spend. The bonus is conditional on the minimum spend within the specified window. Missing the window forfeits the bonus entirely; the spending you did counts as ordinary purchases.

Closing cards too quickly after the bonus posts. Some issuers will claw back bonuses on cards closed within months of opening. Holding for at least 12 months is standard practice.

Misunderstanding “new account” definitions. Several issuers count converting an existing card to a new product as a “new account” for some purposes and not for others. The rules are issuer-specific and worth checking.

The hourly math

The honest assessment of credit-card optimization is that the return on time has declined since the peak years (around 2018-2020 when offers were richer and rules were laxer) but remains meaningful for organized users.

A typical premium-card bonus in 2026 is in the range of 80,000 to 120,000 transferable points, worth roughly $1,000 to $2,200 at smart redemptions. The time required to manage a card application — research, application, ensuring spend hits the threshold, scheduling closure — is in the range of 4 to 8 hours over the life of the bonus pursuit. The implied hourly rate is in the low triple digits, which is a respectable side return.

For users who do not enjoy the activity, the hourly rate may not be worth the cognitive load. For users who find the optimization mildly interesting, the math continues to work.

What to do

If you have not been actively optimizing and you have a strong credit profile, start by surveying the major Chase, Amex, and Capital One offers and identifying any that match your normal spending patterns. Apply for one card at a time, meet the spend, hold the card for at least a year, then move to the next.

If you have been actively optimizing for years, the new news in 2026 is mostly continuity: the cool-off periods are slightly longer, the spending requirements are slightly higher, the headline bonuses are similar to recent years. The rules require a little more bookkeeping and the same basic patterns continue to work.

The category will continue to evolve as issuers continue to balance customer-acquisition spending against bonus economics. The organized customer who is paying attention will continue to capture meaningful value from it.
