# Adjacent News > Adjacent is an indexing and benchmarking company for prediction markets and event contracts. adj.news is an agent-facing forward indexing provider: every index and methodology document below is available as markdown via content negotiation. Append `?format=md` to the URL or send `Accept: text/markdown`. The same data is served from a public, CORS-open, no-auth JSON API at `https://api.adjacent.markets/api/v1/public` (15-min delayed), and as **MCP tools** at `https://mcp.adjacent.markets/mcp` (see https://docs.adjacent.markets/explore/mcp). > Index values are on a **50–150 scale** (`50 + win-probability %`), so 100 = a 50/50 race and `value − 50` = implied win-probability. RED = Republican strength, BLUE = Democratic strength. ## Indices - Catalog (JSON): https://api.adjacent.markets/api/v1/public/indices ## News - [Latest coverage](https://adjacent.markets/news?format=md): recent Adjacent News headlines as markdown, each linking to the full /article/{slug}. ## Methodology and factsheets - [GOVBGD Factsheet](https://adjacent.markets/static/govbgd-factsheet-q3-2026/factsheet?format=md): factsheet as markdown;
