The lens
I care about the mechanics: what price is real, where the spread is, whether there is enough depth to exit, and what the contract will actually resolve to. Politics and geopolitics are often the most interesting markets because they force competing information into one visible number. They can also be the easiest place to mistake a flashy headline for a good contract.
I like Polymarket most when its book is active enough to reward patience and a limit order. I am less interested in a market that only looks good at the midpoint. I also like crypto rails when they make a workflow simpler, and dislike them when they turn a basic action into an avoidable puzzle.
Rules I use
If I cannot explain the resolution rule in plain English, I do not like the trade. If the spread eats most of the edge I think I have, I would rather wait. A good thesis can be a bad trade at the wrong price. No opportunity is still a valid outcome.
I do not pretend every reader should make the same choice. I do make the choice on the page, though. Polymarket wins for me on crypto-native funding and market breadth. Kalshi can be the better product for a conventional verified U.S. account and banking workflow.
Changing my mind
Product evidence beats a tidy prior. I initially would have treated Lightning as unclear from the written documentation alone. The observed BTC deposit interface showed “Deposit Bitcoin instantly with Lightning” and a $10 displayed minimum on August 17, 2026. That is why the site records observations separately from general documentation and corrects itself when better evidence arrives.
