Artificial intelligence is now firmly embedded across investment research, portfolio construction and advice. Its capabilities have evolved alongside the expectations users have for it. Today’s investors and advisors are not satisfied with speed alone. They want to understand how and why decisions are made.
This shift is placing explainability at the centre of modern investing. As algorithms take on a greater role in shaping financial decisions, transparency is becoming critical to building trust, meeting regulatory expectations and supporting better outcomes for both advisors and investors.
AI adoption is reaching a pivotal point
AI adoption across financial services continues to accelerate – particularly because of its ability to process vast amounts of both structured and unstructured data. From earnings reports, market sentiment, global news and social media discussion, AI can analyse information in minutes, replacing what once required teams of analysts working over long periods.
This shift is significant in scale, with BridgeWise’s State of AI for Wealth 2026 report finding 78.3% of respondents globally already use AI tools as part of their investment research, making it no longer early experimentation but mainstream behaviour. In addition, real world applications are already in use, with large asset managers now using AI to scan thousands of company filings during reporting seasons to identify shifts in guidance or any emerging risks much faster than manual methods. This is transforming how opportunities are identified and how risk is assessed.
However, it is important to acknowledge that faster and more informed outputs may not be the better option if they aren’t explainable and traceable. These outputs are not enough if advisors cannot understand how conclusions were reached.
Why is explainability and traceability essential?
Explainable AI refers to systems that clearly show how outputs are generated, including which data points were used and how different factors were weighed in decision making. This is a critical step in financial services, as each decision and piece of advice directly impacts a client’s investments, risk and long term goals.
The main challenge lies in trust.
Despite growing trust in AI, nearly half of all survey respondents, 49.5%, say their main concern is that it may provide incorrect or risky advice, making this the single biggest barrier to adoption. Without clear reasoning behind every decision, even the most accurate systems struggle to gain trust over a human advisor.
Regulators are also increasing scrutiny with the UK’s Financial Conduct Authority making it clear that advisors remain responsible for decisions made using AI and must ensure their outcomes are explainable and auditable. The EU AI Act does the same, introducing stricter requirements around advice transparency, record-keeping and human oversight for high risk systems and investments.
The growing focus places traceability at the centre and is making it no longer acceptable to know just what decision was made, they must now be able to show how and why it was made. Decisions are regularly reviewed, audited and challenged in investing, so advisors moving forward with decisions that do not have a clear record of how a recommendation was generated, face regulatory non-compliance and risk customer relationships.
Explainability is no longer a competitive advantage, it is an expectation.
How is AI supporting better human decision making?
Explainable AI is reshaping how advisors interact with technology. Rather than replacing humans, these processes are being used to enhance human capabilities by accounting for global market data. When models outline their reasoning clearly, advisors can apply their own expertise, experience and knowledge to hold more informed conversations with their clients. This becomes important in the wealth management space, where decisions must align with long term goals.
If an AI model were to suggest reducing exposure to a specific sector, having it be explainable allows an advisor to understand what is driving this, whether it be macroeconomic, company changes or market sentiment. Having this context enables clearer thought processing and stronger client relationships.
Among more advanced users, the role of AI is shifting from validation to discovery, with 44% of frequent users primarily relying on AI to identify new investment opportunities. Again here, before investing in an unknown stock, trust must be established.
Bridging the trust gap in investing
Explainability plays a key role in bridging the trust gap – when systems can provide clear, traceable insights to help advisors and investors understand the outcome, they can mentally validate it, check its logic and understand its reasoning – whether they agree with it or not.
By sharing transparency with a solid user experience, users can then become active and see AI as supplementary and enhancing to their investing model, not predatory or inaccurate. 26.9% and 24% of users respectively cite that proof of data accuracy and human oversight would increase their confidence in using AI for investing.
Explainable models address both these needs by highlighting the source of information and allowing a human to externally verify, helping build confidence in the face of skepticism.
Using AI for a more transparent future in investing
There is no doubt AI will play an even larger future role in the wealth space, but expectations and regulations are shifting. With an increasing demand for investors wanting to understand the reasoning behind recommendations, regulators are placing greater emphasis on accountability and transparency for firms.
Explainable AI supports this shift by making decisions easier to understand, giving advisors and investors clearer visibility into how outcomes are reached and providing greater confidence in the decisions they make or advise.
