The price on screen isnt always the price you pay
On Liverpool vs Villarreal, Polymarkets draw costs 21.8c all-in, while MagicMarkets offers 20.8c
Thats a $12 difference in potential payout on a $100 trade
Across 100 comparable trades, thats $1,200. Same stake, different execution price
Thumper is a free Chrome extension that puts @magicmarkets prices next to Polymarket sports markets, so you can compare the real cost before trading
Check the price
Then take the trade
1/ i built a chrome extension for @magicmarkets that shows you when polymarket isn't the cheapest place to take a sports position
it's called thumper. Free to use, no account required 🧵

Flash sales come and go. They’re nice while they last. But we cannot wave fees for NBA games because we never have fees on NBA games.

judge my mental state based on my lockscreen. wallpaper is what i'm manifesting, notifications are what i'm getting 🦝
georgia, alabama and texas all lost on saturday. auburn walked it off on a last second kick
building sports markets you learn this fast. 80¢ isnt a lock, its a price
somebody holding the 20¢ side had a very good weekend
thumper tip: open the side panel and there's a stake box. type what you'd put in and it shows the payout on each venue
heads up it uses the top of book price, it doesnt walk the order book. quick gut check, not a quote

been building on thumper.
the banner next to the trade box refreshes every few seconds so you can see which venue is cheaper while the game's on.
free chrome extension, no account.

polymarket token or ipo. either way traders care about the same thing: what does it cost to take a position. fees > tokenomics
tonight's nhl, sharks vs predators
polymarket: SJ 45¢, about 46.2¢ once the taker fee hits
MagicMarkets: 45¢
1.2¢ on a coin-flip line adds up. that's what thumper shows under the trade box. disclosure, we built it at MagicMarkets.
when polymarket's cheaper it says so too (brewers vs dodgers tonight, it is)

the 41¢ you see on polymarket sports isnt really 41¢ once the taker fee lands.
thumper puts the all-in number next to the trade box so you dont have to do the math. free, no account.
tell me what breaks 🙏

betdaq closing markets on 21 oct after the matchbook deal. exchanges consolidating while prediction markets keep splitting. interesting time to be building one
