Prediction Market

A prediction market that has to feel like a trading app to crypto traders and like a fixture list to football and eSports fans — in the same five tabs.

Business objective

Build a unified prediction market ecosystem that makes real-world event trading accessible, discoverable and engaging across different audiences — supporting hedging use cases without implying that any position is an effective hedge.

01 — Problems

How can one platform connect financial trading with real-world event prediction?

Three audiences, one product. Switch between them to see how each one behaves — and the problems that behaviour runs into.

Behavioural profile

Different motivations. Different behaviors. One connected prediction market ecosystem.

02 — Research

Behaviour shapes the information architecture.

Four research areas, a competitor review of Polymarket, Kalshi and Predict.fun, and a behaviour matrix that compares the three audiences.

Design principles

01Discovery first

Help users find markets relevant to their interests.

02Familiar interactions

Adapt patterns from financial trading, sports schedules and event predictions.

03Contextual complexity

Show what the task needs instead of every function at once.

04Speed with transparency

Efficient interactions that keep pricing, risk and settlement clear.

05Financial clarity

Balances, positions and outcomes that are easy to understand.

04 — Strategies

Five features, shown on the product.

Every screen is the live prototype: prices tick, countdowns run, and filters, tickets, sheets and toasts respond. Scroll inside a phone or tap through it.

Explore

One discovery feed with category chips, search and a Live filter; every market type shares a scannable card.

01 · FeedOne feed

Crypto rounds, fixtures, multi-outcome and yes/no markets share one card system, filtered by Watchlist, Live and category.

02 · MarketMarket detail

Chance, volume and price history above the ticket. Yes and No show price per share and what the amount would win.

03 · OutcomesMany outcomes

Multi-outcome markets rank every outcome by chance and chart the leaders over time.

1 / 3One feed

User problem
Users need to find relevant opportunities across market categories without excessive navigation or information overload.
Design decision
One discovery feed with category chips, search and a Live filter; every market type shares a scannable card.
UX rationale
Audiences enter through different doors — a coin, a match, a headline. One feed with consistent cards lets each find theirs without learning separate sections.
Expected user benefit
Faster discovery with less navigation.

Up/Down

Directional trading on fixed rounds for crypto, stocks and ETFs: a price to beat, a countdown and two buttons.

01 · RoundsRounds at a glance

Live price against the price to beat, a countdown ring and the current split. One-Tap is on: the stake (5, 10 or 50 USDT) is set once.

02 · One tapTraded in one tap

Up or Down buys at the chosen stake straight away — no confirm step. A notification confirms the order and the position appears on the card.

03 · RoundRound detail

Live price, move against target, the round timeline and a Buy/Sell ticket.

04 · CoverageBeyond crypto

The same round format for stocks and ETFs.

1 / 4Rounds at a glance

User problem
Users interested in price movements need a fast, understandable way to choose a direction, trade and know how it settles.
Design decision
Directional trading on fixed rounds for crypto, stocks and ETFs: a price to beat, a countdown and two buttons.
UX rationale
Framing a price prediction as Up or Down against a visible target removes order-book concepts while keeping pricing transparent.
Expected user benefit
Fewer decisions per trade, with payout and settlement in view.

Matches

An event-centred schedule: sport and game rail, league filters, a date strip, followed teams and campaigns.

01 · ScheduleFixture list

Game rail, leagues and a date strip, with the tournament campaign above the schedule.

02 · FollowingYour teams

Followed teams and fixtures in one list, with kick-off alerts.

03 · MatchMatch markets

Each side’s chance over time, then moneyline, game winner and totals in one ticket.

1 / 3Fixture list

User problem
Sports audiences navigate by games, leagues, teams and schedules rather than financial market structures.
Design decision
An event-centred schedule: sport and game rail, league filters, a date strip, followed teams and campaigns.
UX rationale
Meeting fans in the structure they already use — a fixture list — lowers the cost of a first prediction.
Expected user benefit
Familiar navigation from a match to its markets.

Leaderboard

Category rankings and trader profiles with PnL, ROI and win rate over selectable ranges, public positions and Follow.

01 · CategoriesWhere profits are

24-hour PnL by category opens the rankings.

02 · RankingRanked traders

A podium and list with PnL, ROI and win rate; star a trader to watch.

03 · ProfileTrader profile

PnL, ROI and win rate over selectable ranges, open positions, copy and follow.

1 / 3Where profits are

User problem
Users who want to learn from other traders need transparent performance data to decide whom to follow.
Design decision
Category rankings and trader profiles with PnL, ROI and win rate over selectable ranges, public positions and Follow.
UX rationale
Comparable, labelled metrics make performance legible. Past results do not predict future ones, so the design shows evidence, not promises.
Expected user benefit
Informed strategy discovery.

Portfolio

One dashboard: total value, today’s PnL, position value and available balance, with Active, Closed and Open orders.

01 · ActiveOne dashboard

Total value, today’s PnL, position value and available USDT; active positions with payout if won.

02 · ClosedSettled positions

Won or lost, amount returned, PnL and settlement date.

03 · OrdersOpen orders

Resting limit orders with fill progress and cancel.

1 / 3One dashboard

User problem
Users across many predictions need a clear view of exposure, balances and settlement outcomes.
Design decision
One dashboard: total value, today’s PnL, position value and available balance, with Active, Closed and Open orders.
UX rationale
Financial clarity builds the confidence to keep trading; every position restates price, shares, value, PnL and payout.
Expected user benefit
Transparent monitoring in one place.

The prototype’s Up/Down also lists commodities (gold, crude oil) under its own filter; the strategy scope is crypto, stocks and ETFs.

05 — Key metrics

Measuring participation, trading activity and product performance.

An evidence-based view of how users interact with the prediction market ecosystem. Every figure comes from the analytics dashboard, May–November 2026; derived values are marked as calculated.

Conclusion

Participation scaled fast and is now split almost evenly between crypto and event markets; trading volume kept growing after the July peak in active traders.

The data shows what happened, not why. It doesn’t isolate the effect of any single feature, so no design change is credited with these results. Next: cohort retention after July, and category-level conversion for culture and politics markets.

Source: analytics dashboard — “Daily Trading Volume” (monthly dimension) and “Daily Trading Volume Share by Source” (2026-11). Volume unit not shown in the source.
