RegTech in the US: inside the $19 billion category turning compliance into code

A compliance analyst at a mid-sized US bank used to spend her Monday mornings manually reconciling sanctions-screening exceptions in a spreadsheet. In 2026, the same analyst opens a workflow dashboard that has already disposed of 94% of alerts overnight, flags a short queue for her review, and time-stamps every decision in a regulator-ready audit trail. The rails behind that shift are RegTech, and it is why Fortune Business Insights values the global RegTech market at $19.06 billion in 2025, projected to reach $105.23 billion by 2034 at a 20.0% CAGR, with North America holding a 30.30% regional share and the US market alone projected at $4.86 billion in 2026. A parallel Precedence Research estimate pegs the 2025 market at $19.21 billion growing to $85.48 billion by 2035 at a 16.10% CAGR, with the US market at $5.76 billion in 2025 and the BFSI sector commanding the largest end-user share.

How RegTech became a software category

A decade ago, bank and broker compliance was a paper-heavy, labour-intensive operation. Anti-money-laundering teams reviewed transaction alerts in spreadsheets. KYC files lived in filing cabinets. Trade surveillance ran on overnight batch jobs built in the 1990s. When a regulator came in for an exam, compliance produced binders. When a rule changed, compliance hired more analysts. The unit economics did not scale, and the post-2008 expansion of the regulatory perimeter — Dodd-Frank, EMIR, MiFID II, the Volcker Rule, and dozens of subsequent updates — broke the labour-intensive model.

What replaced it was RegTech. The term was coined around 2015 by the UK Financial Conduct Authority and quickly took hold across the industry. The first-generation vendors — Actimize (NICE), FICO TONBELLER, SAS, Fiserv’s Financial Crime Risk Management, Oracle’s Financial Services Analytical Applications — productised the core AML, KYC, and trade-surveillance workloads. The second wave — ComplyAdvantage, Quantexa, Feedzai, Sift, Socure, Unit21 — built cloud-native, ML-driven alternatives. By the late 2010s every tier-one bank had a RegTech budget, and by the early 2020s every mid-sized bank did too.

The incumbent response, running 2020 to 2025, was to treat RegTech as strategic operating infrastructure rather than a compliance-department line item. Banks moved compliance workloads off mainframes, rebuilt them on cloud platforms, and started measuring program ROI by false-positive reduction, decision time, and regulator-examination outcomes. By 2026, RegTech has matured from a disruption narrative into a software-category investment thesis — the same pattern that played out in payments a decade earlier.

The RegTech market in 2025

The two research houses converge on the category structure. Global RegTech is a high-teens-billion-dollar market growing at 16% to 20% per year. North America is the largest regional market, and the US alone accounts for roughly a quarter of global RegTech spending. BFSI is the dominant end-user segment, followed by healthcare, IT and telecom, manufacturing, and government. AML, KYC, fraud detection, trade surveillance, and regulatory reporting are the five dominant workloads.

Five RegTech workloads inside US financial firms

RegTech at a US financial firm in 2026 has consolidated around five recurring workloads.

The first is anti-money-laundering transaction monitoring and sanctions screening. Every US bank runs real-time and batch screening against OFAC lists, updates watchlists continuously, and investigates alerts under suspicious-activity-report obligations. Modern platforms use ML to reduce false-positive rates, which in legacy systems often exceeded 95%. The overlap with the machine learning systems US financial firms have deployed for credit-scoring and model-risk management is explicit — AML models share MLOps discipline with credit decision models.

The second is know-your-customer identity verification and enhanced due diligence. Digital onboarding uses identity-verification APIs, document capture, liveness detection, and sanctions/PEP screening. The overlap with the open banking rails rewriting who owns access to US financial data is structural — open-banking account tenure and transaction history are now first-class inputs into KYC and identity-fraud models.

The third is regulatory reporting and data governance. US banks submit thousands of regulatory reports per year — Call Reports, FR Y-9C, FFIEC 101, TRACE, CAT — and the data-lineage requirements are severe. The overlap with the regulatory reporting software US banks have adopted to turn compliance into code is direct — regulatory reporting is itself a sub-category of RegTech.

The fourth is trade surveillance and market-abuse detection. Broker-dealers, exchanges, and trading venues monitor for spoofing, layering, front-running, and insider trading. Surveillance platforms ingest order, trade, and communications data, apply pattern-recognition and anomaly-detection models, and generate cases for investigators.

The fifth is policy management, controls testing, and compliance workflow. Governance-risk-compliance platforms, policy-and-procedure management systems, and audit-management tools form the governance layer that sits above the operational RegTech stack. The category has pulled in workflow and case-management patterns from the broader enterprise software industry.

The US RegTech vendor map

The US RegTech vendor map splits into three layers.

At the AML, KYC, and fraud layer, NICE Actimize, Oracle Financial Crime & Compliance, SAS Viya, FICO TONBELLER, ComplyAdvantage, Feedzai, Sift, Socure, Unit21, Quantexa, Hummingbird, Alloy, and Sardine compete across transaction monitoring, identity verification, and case management. Incumbents dominate tier-one bank deployments; cloud-native vendors dominate fintechs and mid-sized banks.

At the regulatory reporting, trade surveillance, and governance layer, AxiomSL (Adenza), Wolters Kluwer OneSumX, Vermeg AGILE, Moody’s Analytics, Nasdaq SMARTS, NICE Actimize trade surveillance, Eventus, ACA Group, Workiva, and MetricStream provide the reporting, surveillance, and GRC platforms. Many of these are enterprise-software veterans that have layered modern cloud delivery on top of decades-old regulatory content libraries.

At the horizontal infrastructure and embedded RegTech layer, identity vendors like Persona, Plaid Identity Verification, Stripe Identity, and Onfido provide API-first building blocks that non-bank fintechs embed into their onboarding flows. Sanctions and watchlist providers like Dow Jones Risk & Compliance, Refinitiv World-Check, and LexisNexis Risk Solutions supply the underlying data. This layer is where most of the venture funding still flows.

What the regulators are watching in 2026

US RegTech is supervised by a patchwork of federal and state regulators. The Federal Reserve, OCC, FDIC, CFPB, SEC, FINRA, CFTC, FinCEN, and state banking departments each touch different parts of the RegTech stack, and model-risk management guidance SR 11-7, third-party-risk-management guidance, and cybersecurity rules all apply.

The first supervisory concern is AML program effectiveness. FinCEN’s AML Act of 2020 and follow-on rules raised expectations around risk-based programs, beneficial ownership, and technology modernisation. Banks that over-rely on legacy systems with high false-positive rates and under-investigate true positives are finding themselves in enforcement posture. The expectation is demonstrable program effectiveness, not just process.

The second concern is model risk and explainability. Any RegTech system that uses ML to triage alerts, rank risk, or score customers falls under model-risk-management guidance. Validation, documentation, ongoing monitoring, and challenger-model review are expected. The supervisory bar has climbed quickly as the technology has matured, and unexplainable black-box models face pushback.

The third concern is third-party risk and cybersecurity. RegTech platforms hold sensitive customer data, connect to core banking systems, and often process millions of decisions per day. OCC heightened standards, FFIEC cybersecurity guidance, and state data-privacy laws all increasingly apply. Banks are expected to supervise RegTech vendors with the same rigour as they supervise internal compliance programs.

What it means for founders and operators

For founders, the RegTech category remains one of the richer opportunity sets in financial-services software. The $19B global market is expanding faster than most adjacent categories, and the structural opportunities — ML-driven alert triage, explainable compliance decisioning, continuous-controls monitoring, embedded KYC for fintechs, next-generation trade surveillance, and regulatory-change management — remain largely unsolved at scale. Defensible startups pair deep regulatory domain expertise with modern data engineering and the model-validation documentation that bank examiners expect.

For operators at incumbent banks, broker-dealers, and fintechs, the cost question has shifted. RegTech investment has grown double-digits per year through 2022-2025, and CFOs are starting to push back. The firms landing cleanly in 2026 are the ones that measured program ROI by false-positive reduction, alert-to-SAR conversion, examination outcomes, and fraud-loss avoidance — not by the number of pilots or partnerships launched. The firms that ran disconnected innovation programs without business-line accountability are the ones justifying the line item to the board.

The bottom line

RegTech is the software category that turned compliance into code across AML, KYC, reporting, surveillance, and governance over the past decade. At $19 billion globally in 2025 and growing at 16% to 20% annually, the category is both structurally expanding and newly scrutinised by regulators themselves. North America leads the regional mix, the US alone is a $5 billion-plus market, and BFSI firms command roughly a quarter of end-user spending. The firms getting the most value from RegTech are the ones that treat it as strategic operating infrastructure — with product management, compliance-outcome accountability, and regulatory governance — not as a compliance-department line item. In banking, as in the rest of financial-services technology, the operational-excellence plays are the ones that compound.
