“Trading app” might be the single most crowded category in every design portfolio on the internet, mine included until recently. TradeView earns its spot here mostly because it isn’t really a trading app. It’s a prediction market built around whether something happens, not what a stock is worth.
The question this product is actually built around isn’t “what is this stock worth,” it’s “will this specific thing happen.” Making that mechanic click for a first-time visitor in one glance, with no tutorial and no mental math required, turned out to be the entire design job.
Almost every screen in this app looks like a normal trading app, because most trading apps genuinely do the same three things. The one screen I’d actually defend in a design review is the prediction event page.
Looked at Polymarket and Kalshi for how prediction markets frame odds in a way a total newcomer can actually parse, then looked at Zerodha and Groww to find the exact gap between trading a stock and betting on an event.
