Overview

Prediction markets are one of the internet's best ideas trapped in one of its worst interfaces. Stips strips away the trading terminal and rebuilds the experience as a game with friends — social, legible, and fun to reason about.

Stips's live markets grid — each prediction shown as a card with plain YES/NO odds, category tags, and live status, browsable at a glance
No order books, no spreads — every market is a card you can read at a glance: a plain question, YES or NO, and where the crowd stands.

Research

The people prediction markets are best for are exactly the people the interfaces scare off.

A Stips market detail on desktop — the question, YES 67¢ / NO 33¢ odds, and a Place-order panel with a play-money stake and a live 'To win $111.94' payout
Where the research landed: a single market as a legible card — plain question, YES/NO odds, live payout — with the order book nowhere in sight.

Interface intimidation

Order books, implied probabilities, and spreads read as 'this is not for you' to anyone who isn't a trader.

→ Drove: A card-based market UI that hides the machinery — you understand your first market before anyone explains it.

Markets are social objects

Casual users don't bet on questions — they bet on questions their friends are arguing about.

→ Drove: Social context on every market: who's in, what the crowd thinks, how the odds have moved.

Real money blocks learning

Nobody learns a new game with rent on the table. Stakes turn curiosity into anxiety.

→ Drove: A play-money beta where the tuition is free.

The problem

The mechanics that make prediction markets powerful — order books, implied probabilities, spreads — are exactly what scares casual users away. The product's core audience bounces off its own front door. That's not a marketing problem; it's a design problem.

The approach

  • 1

    Translated market mechanics into a card-based betting UI that reads at a glance — you understand your first market before anyone has to explain it.

  • 2

    Added the social layer that makes it a game: who's in, what the crowd thinks, and how the odds moved since you last looked.

  • 3

    Shipped a play-money beta so newcomers learn by playing, not by risking — nobody learns a new game with real money on the table.

A Stips market on mobile — the question up top, 67% Yes opening price, big YES 67¢ / NO 33¢ cards, and a 'Challenge a friend' button
The same market on a phone: one plain question, big YES/NO odds, and a tap to challenge a friend — no trading terminal in sight.
Stips's mobile bet sheet — a play-money stake ($25) with +$10/$25/$50/$100 presets and a live 'To win $37.31' payout readout
Placing a bet is a single sheet: pick a stake in play money, watch the potential payout update live — you learn the mechanic with nothing real at risk.

My thought process

Prediction markets already work — as machines. The design job was making them legible as games: something you can read at a glance, argue about with friends, and learn without risk.

What didn't work

The first pass kept a simplified order book, on the theory that transparency builds trust. It read as homework. Trust came from legibility, not disclosure — market cards that read like a group chat did what the slimmed-down trading terminal couldn't.

The outcome

Live in beta on play money, with markets that read like a group chat — proof the barrier to prediction markets was never the concept, just the interface.

The shipped Stips markets board on mobile — live prediction markets across sports, politics, and culture, each a YES/NO card
Shipped and live at stips.bet — real markets in your hand, reading more like a group chat than a trading terminal.
