The Affirm Card supplied 15 of the quarter's 36 points of GMV growth
Affirm's eleventh straight quarter above 30% growth was also its most profitable. The $64bn floor guided for fiscal 2027 implies at most 28% growth, and that gap is where the card-displacement argument gets tested.
The Investor · Invest desk
What happened
- Affirm's fiscal fourth quarter of 2026 was its most profitable, and the eleventh consecutive quarter in which gross merchandise volume grew 30% or faster.
- Fiscal 2027 guidance landed above analyst expectations, with GMV floored at $64bn and revenue less transaction cost margin of roughly 4.15%, above the medium-term guide.
- Affirm Card cardholders more than doubled to 5.2 million, card volume rose 124% to $2.8bn, and those users spend about $4,000 a year each.
- The shares rose as much as 10% on Friday morning to $85.77 before settling at $80.30 by early afternoon in New York, 3.9% above the open.
Why it matters
- What it limits constraint The 30%-plus cadence is what makes the card-share story legible to a generalist buyer; once the guided rate starts with a two, the argument has to be won on credit outcomes and unit margin instead of on momentum.
- Who has to decide decision Guiding contribution margin slightly below what was just delivered tells you where the next dollar goes, which is volume rather than yield, and that is the right allocation only for as long as loss rates sit still.
- What doesn't add up contradiction William Blair reads sub-2% penetration of carded spend as runway while RBC treats the same two guided lines as where a growth or credit disappointment would surface first, and this release supports both readings.
- Who's exposed exposure The substitution claim rides on one product, so if card growth converges toward the rest of the book, Affirm keeps compounding but stops being the thing that replaces a credit card at the point of sale.

Strip the card out and the growth rate loses a third of itself. Card GMV of $2.8bn grew 124% [10], which puts the year-ago card figure near $1.25bn, and total volume of $14.1bn grew 36% [2], which puts the year-ago total near $10.4bn; subtract one from the other at both dates and the non-card business went from roughly $9.1bn to $11.3bn, or about 24% [21]. So the Affirm Card, at a fifth of volume [23], carried close to fifteen of the thirty-six points [22]. That is the product that goes where a credit card goes, which is why the displacement claim from Citizens' David Scharf [13] and from CFO Rob O'Hare [14] is most literally true of the smallest and fastest piece of the company.
The merchant funnel explains part of that mix. Eighty of the top 250 e-commerce sites is 32% coverage [28] against 571,000 merchants signed [9], so incremental volume is arriving through consumers carrying a card off-platform rather than through the largest checkouts adding a button. Run the cardholder cohort forward and it looks larger still: 5.2m cardholders at about $4,000 a year is $20.8bn of annualised GMV, some 37% of the run rate [24], though the cardholder count doubled during the year, so that figure flatters what they actually contributed.
The guide is where the arithmetic gets specific. A floor of $64bn [5] sits 13.5% above the $56.4bn you get by annualising the fourth quarter [17], and against a fiscal year that crossed $50bn [7] it implies at most 28% [18], which makes the eleventh 30% print [1], on the company's own floor, the last one. Guided floors are usually set below what a company expects to deliver, so this number caps downside risk more than it forecasts an outcome.
Margin says something about who is paying for the volume. Revenue less transaction costs of $589m on $14.1bn is 4.18% [19], and the guided 4.15% [5] is three basis points under what was just delivered [19]; revenue meanwhile grew 33% against volume's 36% [3], so yield per dollar of GMV fell about 2% [20] while contribution per dollar rose. That outcome traces to funding and loss costs; pricing was not the driver, and funding costs are the leg most exposed to somebody else's decisions.
On size, William Blair's Andrew Jeffrey puts US carded spend near $9 trillion [16] and Affirm under 2% of it [15]. The fiscal 2027 floor of $64bn is 0.71% of $9tn [26], and a round one percent means roughly $90bn of GMV, which at the guided pace arrives around fiscal 2029 [27]. Durable share gain, then, at a rate that leaves the card industry's income statement mostly intact for several more years.
The number that would settle this is the one this quarter's coverage does not carry: losses. Max Levchin's letter offers "steady credit outcomes" [7], a phrase with no number attached to it, and RBC's Daniel Perlin named growth and credit quality as exactly what those two guided figures were being read for [12]. This is probably wrong, but if the 4.15% holds while delinquencies normalise, the displacement thesis is real and currently underpriced, and if the margin is being held up by pricing a credit cycle takes back, eleven quarters of streak were a funding trade wearing a share-gain costume. The market split the difference inside a session, touching $85.77 and settling at $80.30 [11], which gave back 6.8% of its own good news [25].
What to watch
- Any disclosure of charge-off and delinquency rates set against the 4.15% margin guide for fiscal 2027.
- Whether Affirm Card GMV growth stays near triple digits, and whether the non-card book holds above 24%.
- How many of the top 250 e-commerce sites Affirm adds beyond the 80 it currently serves.

CEO Max Levchin said on the earnings call that the quarter capped Affirm's first consecutive 12-month period of profitability.
- [7]
Levchin wrote to shareholders: "With GMV crossing the $50 billion mark this fiscal year, Affirm's growth can no longer be explained away by the novelty of our product, and our steady credit outcomes demonstrate our commitment to responsible growth with robust unit economics."
- [8]
Active customers jumped 21% to 27.8 million, and transactions per active consumer rose 20% to seven times per year.

Active merchants increased 51% to 571,000.

Affirm shares rose as much as 10% in early Friday trading to $85.77 before settling at $80.30, a 3.9% increase from market open, as of 2 p.m. in New York.
- [12]
RBC analyst Daniel Perlin said the GMV floor and the revenue less transaction cost margin were both in focus as potential negative signals to growth and credit quality.
- [13]
Citizens analyst David Scharf wrote that "Affirm is a long-term secular winner at the expense primarily of the credit card industry."
- [14]
Affirm CFO Rob O'Hare told American Banker that challenging the credit card market is one of the firm's "most immediate opportunities."
- [15]
William Blair analyst Andrew Jeffrey said Affirm is available at 80 of the top 250 e-commerce sites and has just 10% penetration of U.S. e-commerce merchants, representing less than 2% of carded spend.
- [16]
Jeffrey said the Affirm Card is important to capturing the roughly $9 trillion carded U.S. total addressable market, which is multiples the size of Affirm's core e-commerce market.
- [17]
Annualising the quarter's $14.1bn of GMV gives $56.4bn, so the $64bn fiscal 2027 floor sits 13.5% above the current run rate.
- [18]
Measured against a fiscal year in which GMV crossed $50bn, a $64bn floor implies at most about 28% growth, below the 30% threshold of the eleven-quarter streak.
- [19]
Revenue less transaction costs of $589m on $14.1bn of GMV is a 4.18% margin, three basis points above the approximately 4.15% guided for fiscal 2027.
- [20]
Revenue growing 33% against GMV growth of 36% means revenue per dollar of GMV fell about 2.2% year over year.
- [21]
Year-ago card GMV was about $1.25bn and year-ago total GMV about $10.4bn, so non-card GMV grew from roughly $9.1bn to $11.3bn, about 24%.
- [22]
The Affirm Card's $1.55bn of incremental GMV equals 14.9 percentage points of the 36 points of total GMV growth.
- [23]
Card GMV of $2.8bn is 19.9% of the quarter's $14.1bn of total GMV.
- [24]
5.2 million cardholders spending about $4,000 a year is $20.8bn of annualised GMV, 36.9% of the $56.4bn run rate, though the cardholder count doubled over the year so the cohort's actual contribution was smaller.
- [25]
Settling at $80.30 after touching $85.77 means the shares gave back 6.8% of the intraday high.
- [26]
The $64bn fiscal 2027 GMV floor is 0.71% of the roughly $9 trillion U.S. carded total addressable market.
- [27]
One percent of a $9 trillion carded market is $90bn of GMV, which compounding $64bn at the guided 28% reaches during fiscal 2029.
- [28]
Availability at 80 of the top 250 e-commerce sites is 32% coverage of that list.
