Square Card Migration Could Be A Big Deal For Marqeta Stock (MQ)

• In October 2026, Marqeta disclosed that Square migrated its business credit card onto Marqeta’s platform and that Coinbase will use Marqeta’s issuing and processing to power stablecoin backed cards for enterprise customers.
• The Square migration consolidates debit, prepaid, and credit programs, while the Coinbase tie up connects Marqeta to stablecoin custody, conversion, and on chain settlement, tightening its role across both fiat and digital asset payment flows.
• We will now examine how Marqeta's investment narrative could be affected by Square consolidating cards on its issuing platform.

Scan how Marqeta’s card deals fit into a broader shift toward modern issuer processors, and consider list of solid balance sheet and fundamentals (24 results) for ideas beyond payments alone.

Marqeta Investment Narrative Recap

To own Marqeta, you need to believe that a modern issuer processor can stay relevant as large customers scale up, diversify vendors, and push on pricing. The Square consolidation and Coinbase stablecoin work both speak directly to that question, because they test whether the platform can handle complex migrations and new payment flows without losing operational grip.

In the near term, the key swing factor is whether Marqeta can turn these larger, more complex programs into visible net revenue and gross profit traction after guiding to mid single digit growth for Q3 2026. The main risk remains concentration and pricing pressure, so any sign of accelerated volume shift away or weaker take rates would matter more than headline wins.

The Square Credit Card migration looks most relevant for that near term setup. Folding debit, prepaid, and credit onto one issuer processor gives Marqeta a chance to deepen its role with an important customer at a time when Cash App has already started diversifying issuance and when management has acknowledged softer top line expectations.

What really matters is execution on the commercial credit platform Marqeta is touting. End to end capabilities like underwriting, rewards, risk controls, and disputes inside a single integration could help it win more enterprise deals, yet those contracts might come with lower take rates. Your call is whether that trade off still supports the earnings ramp analysts are modelling.

What The Square And Coinbase Deals Mean For The Numbers

Marqeta sits at an awkward intersection between big customer concentration and analyst expectations that already bake in meaningful progress on revenue, earnings, and efficiency by the back half of this decade. The Square and Coinbase wins plug directly into that tension because they reinforce the story that modern issuer processors can still matter for larger, more complex programs, even as pricing and contract terms tighten.

Consensus forecasts currently assume Marqeta can grow top line at 12.1% a year over the next three years while lifting profit margins from 1.5% today to 7.0% on roughly the same timetable. That is a material change in the economic profile of the platform. It implies not just more card volume from deals like Square and Coinbase, but a real shift in the mix of revenue and cost discipline across the whole customer base.

Earnings expectations are where the story gets more demanding. Analysts see profit moving from US$10.4 million today to US$67.1 million by around 2029, with some on the more optimistic end modeling as much as US$163.8 million. That is a step change in absolute dollars, not just a tweak around the edges, and it effectively asks the business to turn commercial wins around Square credit and enterprise stablecoin programs into much higher contribution per dollar of volume.

To reconcile those earnings figures with current share prices, the consensus view looks for Marqeta to trade on a P/E of 33.5x those projected 2029 profits, down sharply from about 187.4x today and still above the 17.1x currently ascribed to the broader US diversified financial group. That gap suggests investors are being asked to treat Marqeta as a structurally higher-quality processor with stronger organic profit potential than a typical financial services stock.

On the capital structure side, analysts assume shares outstanding decline by roughly 5.39% per year over the next three years. If that happens, per share exposure to any earnings progress from Square, Coinbase, and other enterprise deals increases. However, the penalty also rises if net revenue or gross profit trends fall short of expectations. Buybacks or other share count reductions typically help only when free cash flow and profitability remain resilient.

Marqeta's narrative includes US$954.7 million in revenue and US$67.1 million in earnings by 2029. This setup incorporates 12.1% yearly revenue growth and an earnings increase from US$10.4 million today to US$67.1 million at consensus levels.

Uncover how Marqeta's fair value indicates a 10% potential upside to its current price, which may not last much longer.

Exploring Other Perspectives

One alternate angle to watch is pricing. The most cautious analysts worry that lower economics on big renewals could matter more than wins like the Square Credit Card. Before this news, the lowest group only penciled in US$939.8 million of 2029 revenue and US$65.7 million of earnings, a slightly softer path that could shift again as these deals filter into models.
