Neutral interpretation

Bitcoin-linked equities moved more sharply than direct spot vehicles, while event-market probabilities remain low across near-term price milestones.

Coverage depends on available Finnhub and Polymarket fields captured by MRKT Stream on June 9, 2026.

MARKET COVERAGE

Equities and event-driven markets in one schema.

MRKT Stream keeps provider-specific fields explicit so ChatGPT can reason over prices, probability movement, liquidity, and coverage quality without blending units.

Liquid U.S. equities

Finnhub

Prices, movement, company context, and selected news fields when the configured plan returns them.

Event-driven markets

Polymarket Gamma API

Market discovery, event context, active/closed status, volume, liquidity, and probability fields.

Market microstructure

Polymarket Data and CLOB APIs

Provider-dependent order-book, midpoint, spread, activity, and price-history fields.

HOW IT WORKS

ChatGPT -> MRKT Stream MCP -> market-data providers.

A read-only path from question to structured provider context. OpenAI endorsement or partnership is not implied.

01ChatGPT

User asks for market context in a compatible ChatGPT experience.

02MRKT Stream MCP

Read-only tools normalize provider fields into a consistent response shape.

03Market-data providers

Provider APIs determine field availability, timing, coverage, and limits.

CORE TOOLS

Four tools. One market-data layer.

MRKT Stream gives ChatGPT a consistent interface for retrieving structured data across supported market providers.

market_briefsearch_assetsasset_detailstop_movers

ACTIVE TOOL

market_brief

Builds a compact, provider-aware market overview from supported equities and event-driven markets.

Example inputBitcoin-linked assets and markets
Structured outputquotes, movement, volume, liquidity, coverage notes

market_brief

Creates a compact cross-market snapshot across liquid equities and active event-driven markets.

search_assets

Finds matching stock symbols, events, and markets from supported providers.

asset_details

Returns current structured details for one supported stock, event, or market identifier.

top_movers

DATA QUALITY

Neutral when data is partial.

MRKT Stream surfaces timestamps, provider names, partial-success notices, and unavailable fields so unsupported comparisons remain visible.

Unsupported interpretation

Expired market treated as current evidence

Historical or indirectly related markets are not enough for a clean comparison.

MRKT Stream response

Expiry detected. Relevance assessed. Neutral conclusion returned.

Provider context stays separate from stock movement and probability movement.
