I run around $7000, habing started from $500 a couple years ago. My annualized returns have gotten a lot worse with more money, the markets are too thin to sink tens of thousands into it. I manage to make around 0.5%-1% not annualized per month with this capitsl. The thinly traded markets limit investment above 10k, imo. With like $500 though you can double up every couple months, as long as those returns don’t compound.
There's a whole bunch of other bookmakers listing political bets, mainly UK based ones where you should be able to get more liquidity: https://www.oddschecker.com/politics
Are you betting on US politics? You can apparently get x1.06-x1.12 your stake on Trump being the Repulbican nominee for example.
I’ve looked at UK sites, but their odds are unprofitable (at least with what I’m doing). That 6% - 12% stake does sound super nice however, these are exactly the kind od trades I make! If fact they are the only political trades I make. I’m not smart (or stupid) enough to start betting on twitter markets.
