ALEXANDRIA, Va. – July 10, 2026 – Belitsoft, an international custom software development company with deep expertise in financial services technology, today released its analysis of the fintech software development trends shaping the industry in 2026. The report marks a maturation of the fintech industry, which was expected to have global revenues of about $650 billion in 2025, growing at 21% a year. Investment rebounded to $116 billion across 4,719 deals.

“The fintech landscape in 2026 favors depth over breadth – institutional solutions over retail plays, regulatory infrastructure over shiny features, and profitable unit economics over growth-at-all-costs,” said Dmitry Baraishuk, the Chief Innovation Officer at Belitsoft.

Based on the company’s hands-on experience delivering fintech solutions across banking, payments, wealth management, and insurance, the Belitsoft custom software development firm detected eight defining trends that every fintech development team must address in 2026.

Agentic AI Is Reshaping the Stack

The largest change in fintech development for 2026 is agentic AI, or autonomous systems that execute multi-step processes without human interaction. Traditional generative AI provides answers. Agentic AI carries out tasks. That completely alters the design of financial software. 81% of respondents anticipate that agentic AI will be widely used by 2030, with 52% having already incorporated it, according to the University of Cambridge’s 2026 Global AI in Financial Services Report. Banks are deploying agents to hunt money launderers and detect fraud, with humans still signing off on critical decisions. AI-enabled fintechs now account for nearly half of all U.S. fintech deals, up from 25% just two years ago.

This means that development teams must create systems where AI is the engine rather than an add-on feature. 2026 systems use live data streams instead of 30-day-old credit scores for real-time credit decisions. “Point-and-click” banking is giving way to “intent-based” banking, where consumers specify their needs and the system takes care of the rest.

Cost Discipline Is an Engineering Responsibility

Cloud cost optimization is now an engineering-level OKR rather than a finance role. Fintechs must have space to provide new products without sacrificing unit economics due to infrastructure expenditures. Rapid experimentation is giving way to scalable, profitable innovation in the industry. The future fintech stack will be cloud-native, API-first, data-centric, AI-ready and cost-conscious, said the technology leaders at ETBFSI’s Finnext Summit 2026.

Cloud costs are now owned by developers along with performance metrics. Finance teams are unaware of over-provisioned instances or instances with inefficient auto-scaling. Those decisions are made every day by engineers. Choose the instance sizes that match the real load. Define rigid budgets for auto-scaling. Watch costs, uptime, and latency all on the same dashboard. If you don’t understand the cost implications of a change in code, you’re flying blind.

Embedded Finance Is No Longer Optional

Customers now want the financial services they use to be embedded in the platforms they already use, such as logistics apps, SaaS tools, and e-commerce checkout. Your financial product is being developed in isolation if it cannot be embedded. In 2026, fintech applications will be heavily API-driven and modular. Instant invoice financing is provided by a logistics app. At the point of sale, a retail platform offers Buy Now, Pay Later. Freelancers can receive immediate payment with a SaaS tool. This calls for real-time platform data exchange, modular infrastructure, and open banking APIs.

The implication for development teams from an architecture perspective is clear: financial functionality must be highly secure, modular, and API-first. The reason is that vertical software is taking over the workflow and the data and therefore becomes a distribution layer for payments and money transfers.

Real-Time Payments Are the New Default

Businesses and users anticipate smooth digital experiences and instant access to finances. By 2028, instant payments are expected to make up 22% of all non-cash transaction volumes worldwide. Instantaneous bank-based payments like Fed and RTP have now transcended early adoption and established themselves as the norm. In 2026, more nations started or improved their domestic RTP networks. Businesses are shifting to always-on, real-time liquidity models.

This means development teams have to build systems that can settle instantly, work around the clock and handle the fraud risks of irreversible instant transfers.

Identity Is Under Siege

High-quality AI deepfakes have made simple video-call KYC unreliable. Deepfakes attack liveness checks designed for static image fraud. Deepfakes are an emerging systemic threat to digital identity verification. The EU’s eIDAS2 law will require standardized digital identity wallets by late 2026. Verified identity information is no longer recreated at each touchpoint thanks to reusable digital credentials and decentralized identity frameworks, which are establishing a new paradigm where this information travels with the client.

Fintech developers are creating agentic AI workflows for straight-through processing to remove manual breakpoints in the onboarding process. AI creates automatic reporting for compliance, helps document verification, and verifies identification attributes.

RegTech Is a Competitive Edge

Regulatory technology is becoming a competitive advantage rather than a defensive expense. 95% of financial institutions have already expanded RegTech use. For risk and compliance, more than 60% of suppliers and 44% of institutions are making investments in AI agents a top priority. RegTech is now regarded by 64% of enterprises as a crucial component of their control environment. Because of their adaptability and scalability – elastic, API-based infrastructures that can process millions of checks in a matter of seconds – cloud-based RegTech solutions are the preferred choice.

This implies that developers don’t have to add compliance after the fact. It is immediately included in the workflows of applications. 2026 tech agendas are dominated by AI projects.

The Talent Market Reflects the Shift

Software developers are still being actively hired by fintech companies. The necessity for humans who create, manage, and expand the underlying platforms has not been eliminated by AI. Models are not self-deploying. Data engineers, ML experts, and AI engineers are in high demand, particularly those who can produce models. Pay for jobs involving a lot of AI is increasing. The number of jobs available in the fintech sector is set to rise 14% in the UK by 2026. There is a skills gap. Numerous businesses are collaborating with specialized suppliers who have prior regulatory and subject-matter expertise.
