Published in 2026. This report examines developments from 2024–2026.
Executive summary
Between 2024 and 2026, Artificial Intelligence in financial services moved from scattered experimentation toward embedded infrastructure across three areas: credit underwriting, fraud and identity verification, and payments. This shift did not arrive as a single breakthrough; it arrived as a series of concrete, verifiable events — a co-founder-to-co-founder CEO transition at a publicly traded AI lender, an acquisition of a threat-intelligence company by a global payments network, a blocked acquisition that reshaped how a data-connectivity company positioned itself, and quiet integration of AI assistants into consumer financial tools. This report documents those events and the companies behind them, using only information that can be traced to an official company source, a regulatory filing, or established independent reporting. It deliberately avoids repeating unverifiable fraud-loss Statistics, model-accuracy percentages, or market-size projections that circulate widely in industry commentary but cannot be consistently sourced. Readers should come away from this report with a company-level understanding of where AI is actually embedded in financial services today, rather than an impression built on aggregate figures that may not hold up to scrutiny. The report is organized around three functional areas — lending, fraud and identity, and payments — because that is how the underlying companies themselves are organized, rather than around a single generic narrative that would obscure how differently each of these areas has actually evolved.
Coverage period
This report covers developments from January 2024 through the first half of 2026, and is published in 2026 with a last-reviewed date of 2026-07-09. Where a company’s history predates 2024 — for example, founding dates or earlier funding rounds — that context is included only where necessary to explain a development that occurred within the 2024–2026 window. The report will be revisited as material new developments occur; readers relying on it for time-sensitive decisions should independently confirm current details against the official sources listed at the end of this report.
Methodology
Research for this report relied on three tiers of sourcing. The first tier is primary company material: official “about” and leadership pages, product pages, and investor relations disclosures, which were treated as authoritative for facts a company would have direct incentive to keep accurate, such as founding dates, executive titles, and headquarters locations. The second tier is regulatory and legal filings, including SEC disclosures, which were used specifically for corporate events such as leadership changes and acquisitions. The third tier is independent reporting from established outlets, used to corroborate dates and context that a company’s own materials might understate, such as the circumstances surrounding a blocked acquisition. Figures that could only be found in a single vendor-published claim, without independent corroboration, were excluded rather than repeated. This report does not include any original survey data, and it does not attempt to estimate market size, growth rates, or fraud-loss totals, because reliable, independently verifiable figures for these categories were not available at the time of writing.
Sector overview
AI in finance during this period clustered around three functional areas rather than a single unified “fintech AI” category. Credit underwriting and lending saw the deepest structural test, as AI-driven lenders operated through a full interest-rate cycle for the first time, giving outside observers a genuine, multi-year public record rather than a short pilot window. Fraud and identity verification consolidated from point tools toward broader platforms that combine multiple signals — identity, transaction behavior, and device data — into a smaller number of vendor relationships per institution. Payments infrastructure, meanwhile, saw AI become less visible even as its footprint grew, with Fraud Detection and revenue tooling embedded so deeply into platforms like Stripe that they are no longer marketed as standalone “AI features.” Across all three areas, the common thread is that AI adoption in finance during this period looked more like infrastructure hardening than product novelty — banks and fintechs extended and consolidated systems they had already begun building before 2024, rather than adopting entirely new categories of tools for the first time.
Category breakdown
Within lending, Upstart remains the clearest publicly traded example of AI-driven credit decisioning, using alternative data alongside traditional credit variables to price risk for personal, auto, and home-equity loans distributed through more than 100 bank and credit union partners. Within fraud and identity, at least three distinct sub-categories have emerged: identity verification at account opening (exemplified by Socure’s combination of digital, social, and offline signals to catch synthetic identities); unified risk operations platforms that combine fraud, anti-money-laundering, and case management (exemplified by Feedzai’s RiskOps positioning); and orchestration layers that let institutions combine multiple vendors’ signals without a lengthy new integration each time (exemplified by Alloy). A separate but related sub-category, explainable underwriting specifically for regulatory compliance, is represented by vendors such as Zest AI, whose public materials emphasize model explainability for banks and credit unions even though the company’s primary about page does not name its founders. Within payments, the dominant pattern is AI embedded inside existing infrastructure — Stripe’s Radar system for real-time transaction screening, and Plaid’s account-connectivity data increasingly feeding both fintech products and, as of 2026, general-purpose AI assistants such as ChatGPT-based personal finance tools Built In partnership with OpenAI.
Regulatory backdrop
Regulatory attention to AI in finance intensified rather than relaxed during this period. In the United States, the Consumer Financial Protection Bureau has continued to emphasize that existing fair-lending laws and adverse-action notice requirements apply in full to AI-driven credit decisions, meaning lenders such as Upstart must be able to explain a declined application in terms a consumer and a regulator can both understand, regardless of how the underlying model reached its decision. Federal banking regulators have similarly continued to expect banks partnering with AI lenders to maintain independent model-risk oversight rather than deferring entirely to a vendor’s own validation. In the European Union, the phased implementation of the EU AI Act has begun to touch financial services use cases classified as higher-risk, including creditworthiness assessment, which has pushed vendors serving European banks to invest more heavily in model documentation, bias testing, and explainability tooling than might otherwise have been commercially necessary. Companies positioned specifically around explainability, such as Zest AI, are a useful reference point for how the vendor market has organized itself around this regulatory reality, treating explainability as a product feature rather than a compliance afterthought.
Company examples
Upstart, co-founded by Dave Girouard, Paul Gu, and Anna Counselman in 2012, went public on Nasdaq in December 2020 and disclosed a planned leadership transition in February 2026: Girouard moved to Executive Chairman effective May 1, 2026, with Gu — previously the company’s Chief Technology Officer — becoming CEO. Socure, founded by Sunil Madhu in 2012, continues to focus on identity verification for digital account opening. Feedzai, founded in 2011 by Nuno Sebastião, Pedro Bizarro, and Paulo Marques, positions its RiskOps platform as a unified alternative to separate fraud, AML, and case-management tools. Alloy, founded in 2015 by Tommy Nicholas, Charles Hearn, and Laura Spiekerman, provides the orchestration layer that lets banks combine multiple identity and fraud vendors. Stripe, co-founded by Patrick Collison and John Collison in 2010, continues to embed Machine Learning across its Radar fraud system and billing tools. Plaid, co-founded by Zach Perret and William Hockey in 2013, remains the account-connectivity layer underneath a large share of consumer fintech applications, and announced a 2026 integration with OpenAI to bring account context into conversational AI finance tools.
Key developments
Several disclosed events define this period. First, Upstart’s CEO transition from Dave Girouard to Paul Gu, announced in February 2026 and effective May 1, 2026, marked one of the most closely watched governance changes among publicly traded AI-native financial companies, and was framed by both co-founders as a long-planned handoff rather than a response to any single quarter’s performance; Girouard remained on Upstart’s board as Executive Chairman and continued in an advisory capacity to Gu and the leadership team. Second, Mastercard completed its acquisition of Recorded Future, an AI-driven threat-intelligence company, on December 20, 2024, explicitly stating it would integrate Recorded Future’s intelligence into its own cybersecurity, identity, and real-time fraud-scoring products — a concrete signal that payments companies increasingly view threat intelligence as core to fraud prevention rather than an adjacent discipline. Third, the U.S. Department of Justice’s successful effort to block Visa’s proposed acquisition of Plaid, which led Visa to abandon the deal in January 2021, continued to shape how regulators and market participants view further consolidation between card networks and financial-data infrastructure providers through this reporting period, particularly as Plaid subsequently raised a Series D round as an independent company at a valuation Forbes reported at roughly $13.4 billion. Fourth, Plaid’s 2026 partnership with OpenAI represents one of the more visible examples of financial-data infrastructure being extended directly into general-purpose AI assistants rather than remaining confined to purpose-built fintech applications. Fifth, and more subtly, the sustained rate-tightening environment of 2022 through 2024 gave Upstart’s AI underwriting model its first genuine multi-year test outside a benign credit environment, a test that public-market investors and bank partners alike watched closely when deciding how much of their own lending volume to route through AI-driven decisioning versus traditional scorecards.
Risks and limitations
This report has several limitations worth stating plainly. It relies on company-disclosed and independently reported information rather than direct access to any company’s internal model performance data, meaning claims about how well any AI underwriting or fraud model performs in practice cannot be independently verified here and are therefore not asserted. Some companies discussed, such as Zest AI, do not publicly disclose founder names, which limits how completely this report can describe their leadership. The regulatory environment for AI-driven lending also remains unsettled: U.S. banking regulators and the Consumer Financial Protection Bureau continue to apply existing fair-lending and adverse-action requirements to AI underwriting models, and the EU AI Act’s phased rollout is beginning to affect creditworthiness-assessment use cases for institutions serving European customers, meaning some compliance practices described as current in this report may change materially within the report’s own coverage window. This report also cannot assess how individual banks and credit unions are internally weighting AI-driven decisioning against traditional scorecards, since that information is generally treated as proprietary and is not consistently disclosed even by publicly traded partners. Finally, because this report excludes unverifiable statistics, some readers may find it less quantitatively detailed than reports that repeat vendor-published figures; that trade-off is deliberate and is intended to prioritize accuracy over apparent precision.
How this report differs from typical market commentary
Readers accustomed to industry commentary that opens with a large market-size figure or a projected compound growth rate may notice this report does not do so. That omission is intentional: widely circulated market-size estimates for AI in finance vary by an order of magnitude depending on which activities a given research firm counts as part of the category, and none of the commonly cited figures could be traced to a methodology transparent enough to independently reproduce. This report instead treats company-level, independently verifiable events — a CEO transition, a completed acquisition, a blocked deal, a disclosed partnership — as the more reliable unit of analysis, on the view that readers are better served by a smaller number of well-sourced facts than a larger number of numbers that cannot be checked.
Conclusion
The period from 2024 to 2026 was not defined by a single transformative AI product in finance, but by the steady operational embedding of machine learning into lending, fraud prevention, and payments, alongside governance events — Upstart’s CEO transition chief among them — that tested how founder-led AI-native financial companies handle leadership continuity under public-market scrutiny. Readers should treat company-level developments such as those documented here as more informative than aggregate market claims, and should continue to monitor Upstart, Stripe, Plaid, Socure, Feedzai, and Alloy individually as the sector continues to evolve through the remainder of 2026 and beyond.
