Kalshi ingestion, markets, trades, and reward programs are gone, and so are the other-venue filters, logos, coverage entries, and the comparison and learn pages that came with them. Historical Kalshi rows are no longer read.
Public feeds, detail pages, rewards, the public API, SDK types, and MCP schemas follow a Polymarket-only contract. A platform filter the V1 API no longer supports returns 400. Older release notes and posts that mention Kalshi describe the product as it shipped on their date, and each now carries a note pointing here.
