RumorPulse reads real-time sports odds on Polymarket and Kalshi and surfaces the biggest movers. When a market price swings meaningfully before sports media reports why, you see the rumor first — injury news, trade chatter, signing leaks, lineup shifts. We turn publicly traded odds into a fast-moving sports-news feed.
From the order books of Polymarket and Kalshi, where people bet real money on game outcomes, signings, trades, and awards. We poll those public markets every few minutes and compare the new price to the previous one. Any meaningful swing becomes a 'rumor' worth a look on the live feed.
Yes. Polymarket and Kalshi are legal, regulated prediction markets operating in the US. We only read public market prices — no insider data, no scraping of private accounts, no placing trades on your behalf. Aggregating public price data for editorial commentary is standard journalism and fully lawful.
Our fetcher polls Polymarket and Kalshi every few minutes. Every rumor row on the /feed page carries a 'last updated' timestamp showing exactly when the price was last confirmed. If a market is quiet we still log the timestamp so you can see we are watching it.
Headline coverage is NFL, NBA, MLB, and NHL because those have the most active prediction markets. We also surface soccer, tennis, college sports, F1, golf, MMA, and any other league actively trading on Polymarket or Kalshi. The live feed shows every active sport in real time.
