Wall Street already uses AI across back-office processing, compliance, market analysis, and, in some cases, actions tied to investing. The realistic risk is not a single wrong forecast. It is a set of mechanisms: models built on incomplete or stale data, conflicts between a firm’s incentives and an investor’s interests, cyber and fraud exposure, and a systemic concern. Many firms may rely on the same models, data, or vendors, so they could react in similar ways under stress and faster than people can step in.
The official sources cited here treat these as material risks that warrant supervision. They do not show that AI has caused a specific market crisis, and they do not give a reliable figure for how many investment decisions are made by AI. The sections below separate the pathways regulators describe from the events they have documented, and explain where US securities regulation stands.

What “AI in finance” actually covers
“AI in finance” is not one activity. The uses range from answering customer calls and processing insurance claims to predicting market moves and informing investment choices. In this article, “Wall Street” means US capital markets, which are overseen by the SEC. The Financial Stability Board (FSB) works at a global level, so its statements apply across jurisdictions.
| Use category | Examples named in official sources | Source and date |
|---|---|---|
| Operations and customer processing | Operational efficiency; call centres; claims processing | FSB, 2024 summary of an OECD-FSB roundtable; SEC Chair Gary Gensler remarks, June 2024 |
| Regulatory compliance | Named as a potential benefit | FSB, report summary, November 14, 2024 |
| Personalised financial products | Products tailored to individual customers | FSB, report summary, November 14, 2024 |
| Market, loan, and credit analytics | Predictions about markets, loans, and credit | Gensler remarks, June 2024 |
| Investment decisions and operations | AI tools incorporated by market participants, from retail investors to large institutions | SEC Commissioner Mark T. Uyeda, September 2026 |
The spectrum matters because the risk of a given use depends on how much its output is acted on without a person checking it first.

What firms gain from AI
The FSB names operational efficiency, regulatory compliance, personalised financial products, and advanced analytics as the main potential benefits. These gains are the reason firms adopt the tools. They do not remove the need to test systems, manage conflicts of interest, or keep clear lines of accountability.
Read the benefits with their date in mind. The FSB’s 2024 summary of an OECD-FSB roundtable described generative-AI use in regulated financial institutions as exploratory at the time, concentrated mainly on operational efficiency. That is a snapshot of 2024 practice, not a current adoption survey.
How AI-related failures could happen
The failure routes below are mechanisms that could produce harm. None is shown to be inevitable.

AI systems depend on data and models that may be incomplete, erroneous, biased, or out of date. When the data are poor or governance is weak, the result can be flawed analysis, operational disruption, or adverse investment outcomes. Models that are hard to interpret also make it harder for supervisors and internal risk teams to challenge them.
As an illustration, a model fitted to a calm trading period may treat recent relationships between assets as stable. When conditions shift, its outputs can look confident while resting on relationships that no longer hold. This is a hypothetical example, not a documented case.
Conflicts of interest and misleading claims
An automated recommendation or customer interaction may serve a firm’s incentives rather than an investor’s interests. The SEC’s 2023 proposal addressed conflicts tied to predictive data analytics. Its legal status is covered in the regulatory section below.
Gensler’s March 18, 2024 statement addressed a different problem: what firms say about their AI use. He said: “In essence, they should say what they’re doing, and do what they’re saying.” He also said: “AI washing, whether it’s by financial intermediaries such as investment advisers and broker dealers, or by companies raising money from the public, that AI washing may violate the securities laws.” AI-washing, in this context, means overstating or misdescribing how a firm uses AI.

The more serious systemic concern is that many firms could end up in the same position at the same time. If they use common models, data sets, or signals, their trading, lending, or pricing decisions could become more correlated. Diverse strategies usually absorb shocks because some participants buy when others sell. When models share the same logic, they may all sell into the same stress and drain liquidity together.
Speed compounds the problem. Automated strategies can respond at high speed, so a human override may arrive after the market has already moved.
Cyber, fraud, and disinformation
AI widens the attack surface. Data-intensive systems and third-party services create more points where data can be stolen, manipulated, or disrupted. Generative AI can also make fraud and market disinformation more convincing and cheaper to produce, which matters because both can move money or prices.
Rank #3
Concentrated providers and outages
Many institutions may depend on a relatively small set of providers for specialised hardware, cloud infrastructure, and pretrained models. Concentration, limited substitutability, and operational dependence can turn one provider’s outage or failure into a shared vulnerability across firms. A firm with a sound internal model can still be stalled if the cloud service or model interface it runs on goes down.

The gap between a plausible pathway and a documented event is the most important distinction in this topic. The table shows how each pathway is described in the official sources and whether those sources document an AI-caused event.
| Risk pathway | How official sources describe it | AI-caused event documented in these sources? |
|---|---|---|
| Model and data failure | Identified as a material risk in FSB material and in Commissioner Crenshaw’s March 2025 remarks | Not established |
| Conflicts and misleading AI claims | SEC 2023 proposal on predictive-analytics conflicts, withdrawn in June 2025; Gensler’s AI-washing warning, March 18, 2024 | Not established; no case is cited |
| Correlated behaviour and speed | FSB identifies it as a potential financial-stability vulnerability | Not established; no AI-driven flash crash is documented |
| Cyber, fraud, and disinformation | Exposure identified in FSB material and in Commissioner Crenshaw’s March 2025 remarks | No specific AI-generated market manipulation case is verified |
| Concentrated providers and outages | Described by the FSB as a dependency and shared-vulnerability concern | Not established |
Read the last column as a statement about these official sources, not about the whole industry. The absence of a citation does not prove that no incident has occurred. It means none is established by the official material cited here.
A checklist for judging a specific AI use
The official sources do not rank particular systems. The questions below are comparison axes drawn from the risks above, not a scoring method.
- Can the logic be explained and audited, and can a supervisor or internal reviewer challenge it?
- Is the data complete, accurate, and current for the conditions the system will face?
- How quickly can a person pause, override, or switch off the system?
- Are the firm’s incentives aligned with the customer’s, and is the recommendation free of hidden conflicts?
- Does the system depend on a concentrated vendor, cloud provider, or pretrained model that many other firms also use?
- Would it behave like competitors’ systems under stress, and would that similarity matter?
- Does the firm describe its AI use accurately to clients and the public?
Regulatory status and guardrails
The SEC’s withdrawn predictive-data-analytics proposal
The SEC proposed rules in 2023 on conflicts of interest associated with predictive data analytics. The Commission withdrew those proposals in June 2025. The SEC said it did not intend to issue final rules on them, and that any future action, if pursued, would begin with a new proposal.

Existing securities-law obligations and other applicable rules may still matter for AI-related conduct. This article does not attempt a complete legal analysis of them.
Commissioner Crenshaw’s questions
In March 2025 remarks, SEC Commissioner Crenshaw listed questions that regulators and market participants should consider about AI. They concern how governance applies to black-box systems, whether firms meet their legal and fiduciary duties, what they disclose, how vulnerable investors are affected, and what systemic or volatility risks may arise. Her remarks state that her views are personal and not necessarily those of the Commission, so they map the concerns but are not SEC policy.
What the FSB asks of authorities
The FSB’s November 14, 2024 report summary concluded: “The rapid adoption of AI in finance means that authorities should address information gaps for monitoring, assess the adequacy of current policy frameworks and enhance supervisory and regulatory capabilities.” That is the FSB’s stated conclusion and recommendation, not a finding of realised harm. Its 2025 monitoring report adds that authorities face data gaps and a lack of standardised taxonomies as they track AI adoption and related risks.
What the evidence does and does not establish
The official sources do not give a reliable figure for how many investment decisions are made by AI, or how many firms allow models to act without a human check. They also give no figure for losses caused by AI-driven decisions. The one large number in this discussion is context rather than evidence about AI. In June 2024 remarks, Gensler cited $110 trillion as the scale of the capital markets overseen by the SEC. That figure describes market size, not AI investment, adoption, or losses.
Assessing any particular market disruption would require incident-level investigation of the trading or decision systems involved, and the official sources cited here do not provide that. The defensible position sits between alarm and reassurance. The pathways described above are documented as risks that warrant supervision, and the official sources cited here do not show that they have already produced a market-wide loss.
