Marqeta

Overview

Marqeta is the card-issuing platform that fintech rode into the embedded-finance era — and whose fortunes were made, and complicated, by a single customer. Founded in Oakland, California in 2010 by PropertyBridge co-founder Jason Gardner, Marqeta built a programmable issuer-processing platform that lets companies issue physical and virtual cards through open APIs rather than legacy bank processors (Bloomberg via Bank Automation News). Its defining relationship was with Block’s Square and Cash App: Square accounted for 70% of Marqeta’s net revenue in 2020, according to the company’s SEC filings cited at the IPO (Bloomberg via Bank Automation News). By the second quarter of 2026, that figure had fallen to 41% — down five percentage points from a year earlier — as Marqeta posted its second consecutive quarter of GAAP profitability and pushed into stablecoin-backed cards and European money movement (MarketBeat via Sharewise).

From $4.3B private valuation to a $16B debut

By 2020 Marqeta had already become the infrastructure behind much of consumer fintech’s card boom. Reuters reported that August that the Oakland company — then backed by Goldman Sachs and Visa and serving Square, Uber and Instacart — was hiring banks for an IPO after raising $150 million at a $4.3 billion valuation; revenue had doubled in 2019 to around $300 million, and more than 140 million cards had been issued through its platform (Reuters). The listing came in June 2021: 45.5 million shares priced at $27, raising $1.23 billion and giving Marqeta a market value of about $16 billion on debut, with Goldman Sachs and JPMorgan leading the sale (Bloomberg via Bank Automation News). The customer roster named at the time — Uber, DoorDash, Instacart — plus a JPMorgan relationship that put Marqeta behind commercial-card use in Apple Wallet, showed a company embedded in Big Tech’s money movement, but the SEC filings told the concentrated truth: one customer, Square, was 70% of net revenue (Bloomberg via Bank Automation News).

Diversification, slowly: 2025–2026

Marqeta’s post-IPO years were defined by the long attempt to grow out from under Block. In February 2025 the company made two moves at once: it agreed to acquire TransactPay, a UK/European e-money institution and BIN sponsor live in 25 countries across 16 currencies and a principal member of Mastercard and Visa, and it parted ways with CEO Simon Khalaf after two years, installing CFO Mike Milotich as interim CEO (Finextra). The TransactPay deal closed in 2025 and became the backbone of Marqeta’s European push: a partnership with Banking Circle extended account and money-movement capabilities into 30 additional European countries, and Expensify used the new rails to take its corporate card offering from the US into the UK and EU (MarketBeat via Sharewise).

By mid-2026 the diversification was measurable but incomplete. In Q2 2026 Marqeta processed $120 billion in total processing volume, up 32% year over year — its fourth straight quarter above 30% TPV growth — with net revenue of $176 million and gross profit of $122 million, both up 17%, and $8 million in GAAP net income, the second consecutive GAAP-profitable quarter (MarketBeat via Sharewise). The same call disclosed the other side of the story: non-Block TPV was growing more than twice as fast as Block TPV, Block had fallen to 41% of net revenue, and new Cash App card issuance had begun declining around mid-June — roughly 10% below trend, with management expecting “little to no new issuance” by year-end as Block diversified providers (MarketBeat via Sharewise). Milotich framed provider diversification as common practice among large customers and noted Block was still growing across Cash App, Square and Afterpay (MarketBeat via Sharewise).

The 2026 pivot: stablecoins, credit, and a reverse split

Marqeta’s 2026 strategy reaches beyond cards. In September 2026 it partnered with BVNK, the stablecoin infrastructure company, to let customers embed US-dollar stablecoin capabilities into wallets, cards and financial products — users transact in digital dollars at millions of merchants on standard card rails while BVNK handles stablecoin movement and Marqeta keeps issuance, acceptance and bank and network relationships (PYMNTS). The deal has a network-level dimension: Mastercard is one of Marqeta’s major network partners and acquired BVNK earlier in 2026, and all three companies back the Open USD stablecoin standard (PYMNTS). The Q2 call had already disclosed a parallel partnership with zerohash, plus expansion into non-card rails — ACH, real-time payments, push-to-card and wires in the US, UK and EU — and a Real-Time Decisioning fraud product whose gross profit grew more than 80% in the first half, incorporating transaction data from partners including Adyen, Riskified and Signifyd (MarketBeat via Sharewise).

The quarter also marked a financial reset: a 1-for-4 reverse stock split took effect June 30 (GAAP EPS of $0.07 reflects it), the board authorized a new $150 million share repurchase on August 3, and the company ended the quarter with $700 million in cash and short-term investments (MarketBeat via Sharewise). Management guided to slower second-half growth — 12–13% full-year net revenue growth and GAAP net income in the high-$20 million range — citing the Cash App issuance shift, a large renewal’s timing, and tougher comparisons in lending and buy-now-pay-later, where a BNPL customer was load-balancing single-use virtual-card volume among providers (MarketBeat via Sharewise). Three credit programs are slated to launch over the coming quarters: a revolving consumer co-brand, a secured credit-builder with BNPL functionality, and a commercial charge card (MarketBeat via Sharewise).

What this profile does not claim

• It does not claim Marqeta has escaped customer concentration: Block was still 41% of Q2 2026 net revenue, and the profile states both the progress and the remaining dependence.
• The August 4, 2026 SEC filing was not directly retrieved (EDGAR returned 403 in this environment); all quarterly figures rest on secondary reporting of that filing, as documented above.
• It does not state the $1.41B fully-exercised IPO figure; only the $1.23B base raise verified from the fetched Bloomberg reporting is given.
• It does not claim Milotich is permanent CEO — only that he became interim CEO in February 2025 (Finextra) and was described as CEO on the Q2 2026 call.
• It does not evaluate whether the reverse split or buyback created shareholder value; only the facts of those actions are stated.
