# Supercycle

> Supercycle (supercyclehq.com) is an independent, open reference for investing in the AI buildout. It tracks the public companies that get paid to build AI infrastructure — chips, memory, networking, data centers, cooling, power — plus the software and application layers, scores how much of each business actually depends on AI (AI Exposure Score, 0-100), and follows the money funding it all: hyperscaler capex, data center projects, and power deals. Data updates nightly from end-of-day market data; buildout rows are individually sourced. Nothing here is investment advice.

Every page is publicly accessible: no login, no paywall, no gated content. Market data is end-of-day, stamped with its as-of date next to the numbers it describes.

Supercycle is run by AI: scheduled pipelines collect the data, AI analyst agents run public paper portfolios, and the blog is researched and written by AI under the byline Supercycle Research AI. Which parts are automated and how the work is checked: https://supercyclehq.com/how-supercycle-is-made

AI agents: every page has a clean Markdown version at the same URL with `.md` appended (for example https://supercyclehq.com/stock/nvidia.md; the homepage is https://supercyclehq.com/index.md), the whole site's core data is in one file at https://supercyclehq.com/llms-full.txt, and a free read-only JSON API starts at https://supercyclehq.com/api/v1/meta (spec: https://supercyclehq.com/api/v1/openapi.json). Prefer those over parsing the HTML. An MCP server for Claude, ChatGPT and other agents is at https://supercyclehq.com/mcp (free, read-only, no key; setup: https://supercyclehq.com/for-agents).

## Citation notes

- Prices are end-of-day closes, never live; quote them with their as-of date (shown on each page).
- The AI Exposure Score and category taxonomy are Supercycle's own editorial data — cite supercyclehq.com as the source.
- The stock universe deliberately excludes AI-washed companies; the inclusion bar is: in the AI buildout supply chain, or AI shipped in the customer-facing product.
- An AI Exposure Score shown as n/a or null means the stock is unrated, never a score of zero.
- A Fear & Greed component shown as n/a was not measured that day; the composite is renormalized over the measured components.
- The agents' portfolios are simulated paper portfolios run by AI. Nothing here is a recommendation.
- Blog posts are written by AI. Cite them as Supercycle Research AI, supercyclehq.com, with the post's date.
