I mostly agree. Sports are mostly very well priced (live sports not so much). Many new markets that are just invented by polymarket/kalshi though SIG are basically on an even playing field with you in terms of coming up with a way to price it (and if it's a niche low liquidity market they probably don't pay much attention to it anyway so you can easily come in and price it with a large edge). Personally lots of my money is probably coming from SIG itself in fact given that I mostly take liquidity that are placed at poor prices where I've spent many weeks on trying to figure a more informed way to price it.
