# OnePay (One Finance, Inc.): AI strategy

Source: https://www.bankingnewsai.com/fintech/one-finance
Last updated: Oct 16, 2026

*A Walmart-distributed 'everything app' that partners for balance-sheet products (Synchrony cards, Klarna and Upgrade loans) and builds AI itself as a shared platform layer: five support agents, internal agents for every employee, and an MCP server that lets customers bring their OnePay data into ChatGPT and Claude.*

## How is OnePay using AI?

OnePay, the Walmart-backed fintech that renamed itself from One in March 2025, runs AI as a platform layer: five support agents, of which its Phone Agent lifted automated resolution by 60% in 2025, internal agents for every employee, the Penny money companion, and OnePay for Agents, which puts customers' data inside ChatGPT and Claude. It has 6 million monthly active users and was valued above $4 billion in January 2026. Coastal Community Bank or Lead Bank hold its accounts; Synchrony issues its Walmart cards.

## Flagship platform: OnePay AI platform layer (support agents, Arnab, Tokki, Penny, OnePay for Agents)

OnePay says it built AI into its platform as a reusable layer with a shared knowledge base and RAG, a policy system and a pluggable multi-LLM, multi-provider backend. On it run five customer-support agents (Chat, Phone, Co-Pilot, Quality Assurance and Analytical), internal agents such as Arnab (every employee's AI co-worker) and Tokki (a developer agent), a customer AI money companion now called Penny that is available to select customers, and OnePay for Agents, an MCP server that lets customers connect their accounts to ChatGPT, Claude and OpenAI's Dots. ([OnePay](https://www.onepay.com/newsroom/onepay-platform-story), [OnePay](https://www.onepay.com/newsroom/inside-ai-journey), [OnePay](https://www.onepay.com/newsroom/operations-ai-team), [OnePay](https://www.onepay.com/newsroom/arnab), [OnePay](https://www.onepay.com/help-center/articles/onepay-money-companion-opmc), [OnePay](https://www.onepay.com/newsroom/onepay-chatgptanddots))

## Key points

- OnePay says its Phone Agent increased automated resolution of customer issues by 60% in 2025 and its Chat Agent by 20%; a Quality Assurance Agent reviews and grades every contact, and a Co-Pilot Agent works alongside human representatives.
- OnePay for Agents went live on 30 June 2026 as an MCP server; since 12 October 2026 OnePay is also an official app inside ChatGPT on all tiers and inside OpenAI's Dots. Customers' data is shared with Anthropic, OpenAI or another AI platform only when they authorise the connection.
- CTO Moe Matar says AI tooling and other platform changes increased the number of changes OnePay deploys to production more than 5x in 12 months; engineers use a developer agent (Tokki) and an internal CLI that configures Claude Code, OpenCode or Codex.
- The Walmart credit cards announced with Synchrony in June 2025 launched in September 2025; Synchrony's CEO called Walmart its fastest-growing programme ever in January 2026, and its CFO said in July 2026 that adoption is concentrated among Walmart+ customers.
- Klarna has powered OnePay's installment loans at Walmart since a March 2025 deal that replaced Affirm, after One had tested its own buy now, pay later loans in Walmart stores in 2024; CNBC reported that OnePay is the partner granted warrants over more than 15 million Klarna shares in Klarna's F-1.
- Bloomberg reported 6 million monthly active users and $50 billion in annualized payments in June 2026, both double a year earlier, and a valuation above $4 billion in January 2026 after an employee share buyback, up from $2.5 billion in 2024.
- The customer-facing AI is still limited: Penny, the AI money companion, is available only to select customers, is for education rather than account servicing, and its help page warns that AI can make mistakes.

## Regulators it answers to

- [CFPB](https://www.bankingnewsai.com/ai-regulation/cfpb) — One Finance is a nonbank provider of deposit access, earned wage access and loans, so it is in the CFPB's remit; its generative Chat and Phone Agents and the Penny chatbot fall under the Bureau's chatbot guidance, and partner-made credit decisions on its cards and loans under adverse-action rules. See [CFPB Chatbots in Consumer Finance (issue spotlight, 2023)](https://www.bankingnewsai.com/ai-regulation/documents/cfpb-chatbots-in-consumer-finance-2023), [ECOA / Regulation B adverse action (15 U.S.C. 1691(d); 12 CFR 1002.9)](https://www.bankingnewsai.com/ai-regulation/documents/cfpb-ecoa-regulation-b-adverse-action).
- [California CPPA](https://www.bankingnewsai.com/ai-regulation/california) — One Finance, Inc. is licensed by the California Department of Financial Protection and Innovation under California Financing Law licence 60DBO-131026 and is registered under the state's Consumer Financial Protection Law for income-based advances.
- [FDIC](https://www.bankingnewsai.com/ai-regulation/fdic) — OnePay deposits are held at Coastal Community Bank or Lead Bank, Members FDIC, and are insured only through pass-through coverage when its conditions are met, so the partner banks' FDIC oversight reaches OnePay's account programme.
- [FINRA](https://www.bankingnewsai.com/ai-regulation/finra) — OnePay Invest brokerage is offered by One Growth Securities LLC, a FINRA and SIPC member, with clearing and custody by DriveWealth, so the investing product inside the same app answers to FINRA.
- State earned-wage-access regulators — One Finance holds earned-wage-access licences or registrations in Indiana, Kansas, Missouri, Nevada, South Carolina, Utah and Wisconsin, covering the early pay it offers Walmart associates and other workers through OnePay@Work.

## What the record suggests

### Partner for balance sheets, build the AI

OnePay hands credit decisions to Synchrony and Klarna (and personal loans to Upgrade) but writes its own support agents, internal agents and MCP server. Its AI is concentrated in servicing, engineering and distribution rather than in underwriting.

### The most-cited AI numbers are self-reported

The 60% and 20% resolution gains, the 5x deployment rate and the 2-3x click-through come from OnePay's own engineering blog, without baselines or absolute volumes; the user and payment figures come from Bloomberg's unnamed sources rather than company disclosure.

### Opening account data to outside AI shifts the privacy perimeter

Through OnePay for Agents, balances, credit history and loans can flow to ChatGPT, Claude or Dots, after which the AI provider's terms govern the data. Consent is per connection and revocable, but the downstream use sits outside OnePay's control.

### The BNPL reversal is the clearest build-versus-buy signal

One tested its own in-store installment loans in 2024, then in March 2025 made Klarna the exclusive lender at Walmart and took Klarna warrants. In May 2026 Affirm's CEO said, without naming Walmart, that Affirm's volume at that retailer kept growing anyway.

### Walmart distribution is the growth engine

Bloomberg reports users and payments doubling in a year and Synchrony calls the Walmart card its fastest-growing programme, with adoption concentrated among Walmart+ customers; the AI programme is scaling servicing for that inflow.

## FAQ

### Is ONE now called OnePay?

Yes. Walmart's fintech, formed with Ribbit Capital in 2021 and named One after it bought One Finance and Even in 2022, updated its brand to OnePay in March 2025. The legal entity is still One Finance, Inc., based in New York. Walmart is the majority owner. Bloomberg reported in June 2026 that OnePay had 6 million monthly active users and $50 billion in annualized payments.

### How does OnePay use AI?

OnePay runs five AI agents in customer support (Chat, Phone, Co-Pilot, Quality Assurance and Analytical) and says its Phone Agent lifted automated resolution by 60% in 2025 and its Chat Agent by 20%. Employees use Arnab, an internal AI co-worker, and engineers use the Tokki developer agent. Customers can try Penny, an AI money companion for select users, and connect OnePay to ChatGPT or Claude through OnePay for Agents.

### Does OnePay work with ChatGPT or Claude?

Yes. OnePay for Agents, launched on 30 June 2026 as an MCP server, lets customers connect OnePay to Claude, ChatGPT or locally hosted agents such as Claude Code or Codex. Since 12 October 2026 OnePay is also an official app inside ChatGPT on free and paid tiers and inside OpenAI's Dots. Data is shared only after the customer authorises the connection, and access can be revoked.

### Is OnePay a bank?

No. OnePay (One Finance, Inc.) is a financial technology company. Banking services are provided by Coastal Community Bank or Lead Bank, Members FDIC, with pass-through deposit insurance. Its CashRewards Mastercard is issued by Synchrony Bank, OnePay Later loans are powered by Klarna and issued by WebBank, and brokerage runs through One Growth Securities LLC, a FINRA member.

### Who issues the Walmart OnePay credit card?

Synchrony. OnePay and Synchrony announced the programme in June 2025, with a general-purpose CashRewards Mastercard and a Walmart-only card, both managed in the OnePay app and underwritten by Synchrony. It launched in September 2025; Synchrony's CEO called it the company's fastest-growing programme ever in January 2026, and its CFO said in July 2026 that adoption is strongest among Walmart+ customers.

### Does OnePay offer buy now, pay later with Klarna?

Yes. Since a March 2025 agreement, Klarna exclusively powers OnePay installment loans at Walmart, online and in stores, making the underwriting decisions on loans of 3 to 36 months; OnePay received warrants over more than 15 million Klarna shares. In January 2026 the two announced Swipe to Finance, which will let customers convert completed OnePay debit card purchases into installment loans.

### Who regulates OnePay?

As a nonbank, OnePay falls under the Consumer Financial Protection Bureau and state regulators: One Finance is licensed by California's DFPI and holds earned-wage-access licences in states including Indiana, Kansas, Nevada, Utah and Wisconsin. Its deposits sit at FDIC-insured Coastal Community Bank or Lead Bank, and its investing arm, One Growth Securities, is a FINRA member. It serves 6 million monthly active users.
