What stands out to me about Thumper is how much of the price checking process it brings together in one place. imagine following several football games before kickoff. Manually checking every market across multiple platforms takes time, and comparing headline prices alone doesn’t always show what you’d actually get when you place an order. Thumper lets you compare prices across Polymarket and MagicMarkets, inspect order book depth and potential price impact, calculate potential payouts, and set alerts when a significant price difference appears. that makes it more than a quick price checker. it gives you more information to evaluate before choosing where to take a position. it won’t predict the match or guarantee an edge, but it can help you avoid deciding without checking the available prices first. worth exploring if sports prediction markets are part of your regular workflow @magicmarkets

this is actually a shocking discovery to me the price you see isn’t always the price you actually get. for people who follow sports markets on Polymarket, check this out. Thumper is a free Chrome extension from @MagicMarkets that lets you compare Polymarket prices with MagicMarkets without switching between tabs. Here’s a real example from the UCL market for Stuttgart vs Atlético Madrid: Atlético Madrid was priced at 47¢ on Polymarket, but Thumper showed 46.7¢ on MagicMarkets, all-in per $1 payout. That’s a $1.50 difference in winnings per $100 paid out, according to the comparison. The reason? Polymarket’s displayed price doesn’t include its 1.25¢ per-share taker fee, while MagicMarkets’ quoted odds are all-in. A simple tool, but a useful reminder to compare the actual cost before making a decision. great product from @tebrabbit and the @MagicMarkets team.

Paying fees on market orders? Are you high?

Follow the rabbit.

Ok little one: Betting on soccer is like guessing which team scores more goals. Fancy bets give the weaker team a head start so games feel fair, and sometimes you get your candy back if it ends close. Most prediction apps only do plain yes or no. They can't handle the fancy head starts. Magic Markets gathers candy piles from 25 different stores into one big shared box. Now the fancy bets work with no extra cost, and the box stays full even while the game is playing.
