Real-world deployments include Goldman Marquee + Marquee AI, JPMorgan IndexGPT / SpectrumGPT, BlackRock Aladdin Copilot, Morgan Stanley AI @ MS for FA-side use, and BloombergGPT productized via Bloomberg Terminal AI. The two failure modes that dominate operational design are **hallucination** (LLM generates a "fact" that does not appear in the source) and **stale-state interpretation** (LLM responds based on training data rather than current feed). Mitigations are layered: retrieval-augmented generation (RAG) against the actual feed, structured-output constraints, citation-required outputs, model-card + version stamping, prompt + output logging for compliance audit. The audit-trail requirement traces back to **SR 11-7 (US Fed model risk management)**, **MIFID-II RTS 6 (EU algo governance)**, **FSA AI principles (Japan)**, and **FCA AI in financial services** guidance — all of which require the deployer to reproduce any AI-driven decision in post-hoc supervisory review. ## Wiki route This entry sits under [[agent-economy/INDEX|agent-economy index]].

The feed includes news, prices, fundamentals, regulatory disclosures, corporate-action notifications. - **Reuters Eikon / Refinitiv Workspace** (now LSEG Workspace post-LSE acquisition) — peer to Bloomberg with stronger Western news + macro feed - **Nikkei feed** (Nikkei QUICK) — Japan-specific corporate disclosure + JGB / equity / FX news - **Exchange direct feeds** — TSE, OSE, NYSE, NASDAQ, CME, LSE direct binary feeds via ITCH / OUCH protocols; latency-sensitive HFT path - **Regulator releases** — EDGAR (SEC), TDnet (JPX), Companies House (UK), AMF (FR), MAS / BaFin / ASIC releases; usually scraped or via licensed redistributor - **Corporate IR releases** — corporate press release wires (BusinessWire, PR Newswire, KYODO, JIJI in Japan); LLM-friendly because text-rich - **Alternative data** — satellite (Planet Labs), credit card spend (Yodlee, Plaid), web scraping (compliant), ESG (MSCI, Sustainalytics) **Why ingest is non-trivial**: each source has its own licensing, latency, schema, and access pattern. A production pipeline must normalize all of them into a single structured event stream before feeding the LLM. The 2025-2026 reference architecture uses Kafka / Kinesis / Pub/Sub at the bus layer with Avro / Protobuf schemas per source type. ### Stage 2 · Interpret · LLM ingestion **The LLM options** (2026-05): | Model route | Public provenance that can be cited | Finance specialization | Production validation boundary | |---|---|---|---| | **BloombergGPT research model** | BloombergGPT paper and Bloomberg's public AI materials | Trained and evaluated for financial-language tasks in the published paper | Do not infer external API availability or a specific Terminal production model from the research paper | | **General frontier API** | Provider model cards / API documentation for Anthropic, OpenAI or Google | General-purpose; finance behavior depends on grounding, prompts, tools and evaluation | Pin the exact model ID / date and evaluate on licensed, time-aligned financial data | | **Cloud-hosted tuned / grounded model** | Cloud provider documentation plus the customer's own tuning / retrieval configuration | Can be adapted with enterprise data subject to product support | Record base model, retrieval corpus, access controls, region and change policy | | **Institution-specific model** | The institution's public technical paper or product disclosure | Potentially finance-specific, but scope varies | A product name or trademark is not evidence of architecture, training corpus or production use | | **Domestic-language model** | Vendor model card and benchmark report | Language / domain performance must be measured for the target Japanese financial task | Verify licensing, tokenizer / context limits, data residency and human-review controls | Sources: ^[https://arxiv.org/abs/2303.17564] ^[https://www.bloomberg.com/professional/products/ai/] ^[https://docs.anthropic.com/] ^[https://platform.openai.com/docs/models] ^[https://cloud.google.com/vertex-ai/generative-ai/docs/learn/models] **Why finance-tuned vs general matters**: a general LLM trained on web data is weaker at parsing 10-Q / 有価証券報告書 / IFRS financial statements than a model fine-tuned on millions of such documents. BloombergGPT's 2023 publication (arxiv.org/abs/2303.17564) demonstrated material outperformance on finance-specific benchmarks vs general LLMs at the same parameter count. The trade-off: BloombergGPT is not externally licensed; firms wanting equivalent capability must either license Bloomberg's productized Terminal AI surfaces or fine-tune a general model on their own finance corpus. **Interpretation operations** (what the LLM is asked to do at this stage): - **Event extraction** — "extract M&A announcements from this news flow" - **Sentiment scoring** — "sentiment of this earnings call transcript on a -1 to +1 scale" - **Summary** — "summarize the key changes in this 10-K vs prior period" - **Q&A retrieval** — "what did the CFO say about FX hedging?" against a corpus - **Scenario generation** — "given this central bank statement, generate three plausible market reactions" - **Structured-data extraction** — "extract net income, revenue, EPS from this earnings press release" ### Stage 3 · Route · signal → trading system The LLM output is a **structured signal**, not a trading order. The signal carries the LLM's interpretation as a typed feature that feeds: - **Discretionary PMs / traders** — signal surfaces in Bloomberg Terminal / internal portfolio screen as a recommendation with confidence + citations - **Systematic strategies** — signal becomes a feature in a multi-factor model (e.g. "news_sentiment_score" combined with traditional momentum / value factors) - **Risk management** — signal flags scenarios that change the portfolio's tail-risk estimate - **Order routing** — for execution algo, signal influences which child-order tactic to use (e.g. heightened sentiment volatility → more conservative TWAP) **Critical design choice**: the LLM does NOT directly emit trading orders. It emits **structured features** that downstream systems consume under their own risk controls. This boundary is what keeps the pipeline within MIFID-II Article 17 + RTS 6 + FIEA Article 38-2 + Reg SCI compliance. ### Stage 4 · Execute · deterministic algo + pre-trade controls The execution layer is **unchanged from non-AI algo trading**. Pre-trade risk controls (price collar, size cap, repeated-order velocity, account-level exposure), kill-switch, post-trade surveillance — all apply identically. The AI signal flows in as one of many inputs to the execution algo; the algo's decision logic is deterministic and auditable. This is the **key safety property** of the production architecture: AI is on the **idea-generation side**; deterministic systems are on the **execution side**. A regulator examining a trade can trace the order back through the execution algo's deterministic logs, and separately examine the AI's signal-generation logs. ## Real-world deployments · 2026-05 public disclosures ### Goldman Marquee + Marquee AI Goldman's institutional client portal **Marquee** has integrated LLM-driven analytics layered over Goldman's proprietary market data + research corpus. Marquee AI provides PMs with conversational interface for research retrieval, scenario simulation, and trade idea generation. Public disclosure has emphasized PM-facing use, not direct execution; trades that result still go through Goldman's execution algo with full risk controls. ### JPMorgan IndexGPT / SpectrumGPT **IndexGPT** (launched 2024-2025): LLM-driven thematic basket construction. User specifies a theme in natural language ("AI infrastructure exposure with low correlation to large-cap tech"); IndexGPT proposes constituent weights based on JPM's internal LLM + structured-feature engine. The output is a **basket recommendation**; users decide whether to trade it. **SpectrumGPT** (compliance / research-side): LLM for compliance document review, research surfacing, and trade rationale documentation. Internal-facing; not customer-facing. ### BlackRock Aladdin Copilot Aladdin is BlackRock's portfolio risk and analytics platform used internally and licensed to ~$21T of assets across institutional clients. **Aladdin Copilot** layers Cohere-powered conversational AI on top, providing PMs with natural-language access to portfolio state, risk analytics, and what-if scenarios. PM-facing; does not emit trades directly. ### Morgan Stanley AI @ Morgan Stanley OpenAI-powered FA-facing assistant for retrieving research from MS's 100K+ document corpus, drafting client communications, and answering procedural questions. FA reviews and approves before any communication goes to client. Not a market-data interpretation pipeline per se but the largest publicly disclosed LLM-in-finance deployment by transaction count (FA queries per day). ### Bloomberg Terminal AI · BloombergGPT productized BloombergGPT was research-published 2023. By 2024-2025, Bloomberg productized LLM-driven surfaces in the Terminal: natural-language search across feed, summary of long news articles, Q&A against earnings transcripts, sentiment-tagged news flow. Terminal users access these as features rather than calling the LLM directly. ### Renaissance / Two Sigma / Citadel internal AI research Not publicly disclosed in detail. Public hiring patterns + paper publications indicate substantial in-house LLM and ML research targeting market data interpretation. Production-trading impact is opaque by design (alpha-generating firms don't disclose). ### Japan-specific · Mizuho / SMBC / MUFG internal LLMs Mizuho M-AI Insight, SMBC GAI, MUFG internal AI — all deployed at scale for internal use across compliance, research, and customer-service-support. Public disclosures emphasize internal use; customer-facing financial decisions remain gated through human reviewers. ## Hallucination control · five-layer defense LLMs reliably hallucinate. In finance, a single hallucinated number can produce a real loss. The 2026 production defense layers: 1. **Retrieval-Augmented Generation (RAG)** — the LLM is given the actual source documents (news article, filing, transcript) as context; output is conditioned on the retrieved text. Reduces "from-memory" hallucination but doesn't eliminate it. 2. **Structured output constraints** — require LLM to output JSON conforming to a schema (e.g. `{"event_type": "M&A", "acquirer": str, "target": str, "value_usd": float, "citation": str}`). Format constraint reduces free-text fabrication. 3. **Citation requirement** — require LLM to include a span citation (`"citation": "Reuters article ID 12345, paragraph 3"`) so downstream systems can verify the claim against source. If citation doesn't resolve, the output is rejected. 4. **Confidence threshold** — discard outputs below a calibrated confidence (using log-prob or self-consistency sampling). Routes uncertain cases to human review. 5. **Cross-validation** — run multiple LLMs against the same input and compare; disagreement triggers human review. No single layer is sufficient. Production systems compose 3-5 of these. The audit trail logs **every layer's verdict** for the regulator to examine. ## Audit trail requirement · compliance composition The audit trail must reproduce the LLM-driven decision in post-hoc supervisory review. The 2026 reference fields: | Field | Why | |---|---| | **Input data hash + timestamp** | Reproduce the inputs that led to the decision | | **Model identifier + version + checkpoint** | Reproduce the exact model that produced the output | | **Full prompt + system prompt** | Reproduce the LLM call | | **Full output text** | Show what the LLM said | | **Structured-output validation result** | Show whether output conformed to schema | | **Citation validation result** | Show whether claims trace to source | | **Confidence score / log-prob** | Show calibrated certainty | | **Downstream consumer system + decision** | Show what was done with the LLM output | | **Final trade / signal / recommendation** | Show end-to-end traceability | | **Human review event (if any)** | Show whether HITL was triggered | The **logging cost** is non-trivial: a high-volume pipeline can generate terabytes/day of audit logs. The 2026 reference architecture uses tiered storage (hot: 30 days in Postgres / TimescaleDB; warm: 1 year in S3 / GCS; cold: 7 years in Glacier / Archive Storage) to satisfy retention requirements (SR 11-7: 5-7 years typical; MIFID-II RTS 6: 5 years; FIEA: 10 years for some records). This composition is the operational realization of the **deployer-accountability** principle in [[agent-economy/agent-legal-tax-liability-framework|agent legal and tax liability framework]] and the regulatory frame in [[agent-economy/ai-driven-trading-regulation-japan-2026|AI-driven trading regulation Japan 2026]]. ## Latency tier · what LLM can / cannot do | Latency tier | LLM applicable? | Use case | |---|---|---| | **HFT / microsecond** (binary feeds → orders) | No (LLM inference is 100ms-10s) | LLM cannot live in this loop | | **Intraday quant** (seconds-to-minutes) | Yes (for signal generation, not direct execution) | Sentiment / event-extraction signals | | **Day-trading / swing** (minutes-to-hours) | Yes | Earnings call interpretation, news flow analysis | | **Position / portfolio management** (hours-to-days) | Yes | Research synthesis, scenario simulation, portfolio rebalancing recommendations | | **Strategy research / backtest** (offline) | Yes (heavy use) | Generating hypotheses, summarizing literature, drafting strategy documentation | The 2026 production reality: LLMs are concentrated in the **research / portfolio / signal-generation tiers**, with deterministic systems handling the **execution tier**. Crossing the boundary (LLM directly issuing orders without deterministic algo) is technically possible but regulatorily and operationally avoided. ## Composition with agent-economy stack This pipeline is the **upstream signal-generation side** of the agent-economy.
