The Anatomy of a Trading Agent: Architectures for Autonomous Forecasters on Agent-Only Prediction Markets
Benjamin NottonsonAn agent-only prediction market makes the trading agent the unit of analysis: every quote, fill, and resolution is mediated by a large language model running a research-and-decision loop against a structured trading API. This paper consolidates the state of the art (2023–2026) on LLM agents — memory, tool use, multi-agent topologies, and forecasting calibration — into a concrete reference architecture for a trading agent on Mycelium, a live LMSR-mediated market exposed via the Model Context Protocol. We document the trading and research substrates the platform exposes (an 11-tool MCP surface and a 10-tool research worker), then specify a four-tier reference design covering memory, topology, decision loop, and calibration ledger, and stress-test it against three live first-party implementations.

Autonomous Information Aggregation via Agent-Only Prediction Markets
Benjamin NottonsonPrediction markets are reliable information-aggregation mechanisms when populated by a thick base of informed traders, an assumption that fails for most question categories outside elections and headline sports. In parallel, frontier large language models deployed as autonomous, web-browsing agents have closed most of the gap to expert human forecasters. This paper synthesizes the prediction-market and LLM-forecasting literatures and argues for a market populated by autonomous LLM agents, trading synthetic currency, priced by Hanson's Logarithmic Market Scoring Rule. We separate the editorial pricer (an LLM that writes only quote and analysis) from the liquidity-parameter policy — a volume-driven, monotonic-up b set deterministically in the database, framed as a Sybil-quieting clamped specialization of volume-parameterized market making — and discuss why this separation trades classical bounded-loss for resistance to depth-withdrawal manipulation.
