AI is rapidly expanding across finance, but most agentic offerings have yet to reach core production systems. Only 10% of enterprises are using AI tools in a meaningful, production-grade way. Not because of a lack of interest, but because connecting AI to core systems to trade capture, risk, and surveillance is still a work in progress.
These systems offer the greatest opportunity for AI to simplify finance operations through efficient workflows and live trading queries. Yet, legacy systems force this technology to operate in isolation. The volume of architecture connected to traditional platforms often creates this constraint.

The financial services industry has forced firms to adapt core architecture rather than replace it, preserving operations, but limiting AI compatibility. Now, the challenge is incorporating AI into these existing systems without forcing an infrastructure replacement that would cause platforms to pause or fail.
To bridge the gap between existing systems and modern demands, firms need an architectural layer to help bridge legacy access, implement a governed AI gateway, and introduce AI-native workflows within trusted guardrails. With the right foundation, firms can extend these capabilities directly into production systems and utilize the full value of AI.
Taming the legacy stack without rewiring it
Years of regulations, acquisitions, asset-class specialization, and incremental development without a shared core have created an extensive stack of internal software required to keep operations running – a stack that was never designed to support responsive, AI-driven interaction.
Rather than rebuilding these systems, financial institutions are introducing an architectural layer that unifies access across fragmented infrastructure. This virtualized approach eliminates the need for costly rewiring while allowing organizations to consolidate access to both static and streaming data.
Instead of adding complexity, it creates a simpler path to deploying AI within existing environments.
IT teams can start this process by establishing a single abstraction layer across fragmented systems, allowing technology integration while applying entitlements at the data layer. In practice, this would allow:
- Natural-language interrogation: Organization-specific data through chatbots and AI assistants.
- Virtualization of systems: Abstraction of all systems behind a permission-aware access point.
- Safe interaction: AI accessible touchpoints within operational infrastructures.
When organizations effectively apply abstraction layers to existing legacy architecture, AI can improve functions while interacting with internal systems through a controlled, permission-aware layer.
A controlled gateway for AI interaction
Abstraction layers are most effective when financial institutions apply them with gateways for AI access. When organizations apply these models together, this infrastructure creates a controlled AI interaction layer that provides a deliberate medium for producing deterministic, repeatable outputs.
Agents can then access data exclusively through the created pathway. This architecture creates transparency and provides for the application of a consistent set of data and functional access controls.
Ultimately, it allows stakeholders to gain confidence and trust, allowing agentic solutions to migrate from an assistive layer to an operational one capable of coordinating workflows, executing logic, and interacting with live systems.
Through this channel, agents can operate within defined policies and fully log all outputs, verifying repeatability and providing compliance teams with unified oversight of operations. A single control plane can grant permissions, log events, and instantly kill defective outputs, assuaging regulatory concerns.
These capabilities allow AI to expand financial institution growth in production-ready technological environments.
Accelerating development inside trusted boundaries
Once these foundations are in place, AI development can accelerate inside trusted boundaries. By doing so, organizations can reduce code surface area and shorten audit cycles.
Within these types of environments:
- AI is equipped with proper boundaries for successful development.
- Agents can generate layouts, workflows, and full applications.
- AI can operate inside transparent and fully auditable runtimes.
Advanced coding can often power this controlled scale, offering development workflows that promote multimodal interaction, including voice, visual, and text. These capabilities further facilitate AI to fully operationalize efficient workflows across financial organizations.
However, when implementing AI adoption pathways, many organizations are now working through how to scale these capabilities consistently across systems. Financial firms facing this dilemma should follow the example of other industries.
The shift from rebuilding to building on top
Other industries have already solved a similar challenge of rebuilding their technology stacks much earlier in the development process. When this issue arose, they standardized their foundation across their industry, focusing on differentiated delivery rather than excessive rebuilding.
This often meant establishing application engines, a feature now used in gaming (Unity/Unreal), E-Commerce (Shopify), and general CRM (Salesforce).
If IT teams adopted these systems, purpose-built for finance, financial firms could focus primarily on delivery.
An engine could lay the foundation for virtualized legacy access, AI-governed gateways, and AI-native development within trusted guardrails, avoiding a full infrastructure replacement and establishing a safe way to integrate technology that reduces manual reconciliation.
A new foundation in financial systems
As AI moves deeper into core financial systems, the opportunity is not just in deploying models but rethinking how software is built and operated. Application engines provide a path forward by allowing firms to integrate AI into live systems, scale workflows, and generate new functionality from human intent, all within a governed environment.
