What Is a Prediction Market? Plain Answers, No Jargon
Answer engines, AI assistants and buyers all reward pages that define the category properly. Here is exactly what you are building, in language your investors and regulators will also understand.
Prediction Market
A prediction market is an exchange where people trade contracts whose value depends on the outcome of a future event. Prices sit between 0 and 100 (or 0 and 1) and represent the crowd's live probability estimate. If the event happens, Yes shares settle at full value and No shares at zero, and vice versa.
Event Contract
An event contract is the tradeable unit of a prediction market: a binary or multi-outcome instrument tied to one clearly worded question with a defined settlement source and expiry. Kalshi lists CFTC-regulated event contracts; Polymarket settles equivalent positions on-chain using oracle reports.
Prediction Market Platform
The full software stack behind that trading: market creation tools, a matching engine or AMM, wallets and payments, oracle-based settlement, risk and compliance controls, admin dashboards and the trader-facing web and mobile apps. That stack is what Capermint builds for you.
Prediction Markets Just Became a Mainstream Financial Category
In little over a year, event trading went from a crypto curiosity to a multi-billion-dollar monthly market. Operators launching now are early to a category that is still compounding — and the platform you launch on decides whether you capture it.
Figures are third-party market estimates (Polymarket, Kalshi, TRM Labs, industry press, 2026) and vary by source. Shown to size the opportunity, not as guarantees.
Three Proven Prediction Market Architectures
Kalshi and Polymarket look similar on the surface but run on completely different rails. We build all three models, and we tell you honestly which one fits your licence, market and budget.
Regulated Exchange Model
The Kalshi approach: fiat in, fiat out
A centralised exchange listing event contracts under a financial licence, with a central limit order book, fiat deposits, custody and full KYC.
- ✓Central limit order book (CLOB) matching engine
- ✓Fiat payments, banking and custody integrations
- ✓KYC/AML, suitability and position limits built in
- ✓Designed for CFTC-style or local regulatory regimes
Decentralised Model
The Polymarket approach: on-chain settlement
Smart contract markets on chains such as Polygon or Base, with stablecoin collateral, non-custodial wallets and oracle-resolved outcomes.
- ✓CTF-style outcome tokens and hybrid CLOB or AMM liquidity
- ✓UMA or Chainlink oracle settlement flows
- ✓USDC collateral, gasless transactions, wallet onboarding
- ✓Audited Solidity contracts and subgraph indexing
Hybrid & Play-to-Predict
Free-to-play, sweepstakes or virtual currency
Prediction mechanics without real-money trading: virtual points, sweepstakes entries or engagement-led forecasting for media, brands and enterprises.
- ✓Virtual currency economy with rewards and leaderboards
- ✓Sweepstakes-compliant structures for restricted regions
- ✓Ideal for audience engagement, media and fan platforms
- ✓Upgrade path to real-money once licensed

The Mechanics, Explained the Way We Build Them
Buyers who understand the machinery make better platform decisions. These four mechanisms are the heart of every serious prediction market — each one a deliberate engineering choice.
Prices Are Probabilities
Every contract trades between 0 and 100. A Yes price of 67p means the market believes there is a 67% chance the event happens. Winning shares settle at 100p, losing shares at 0p. This is why prediction markets aggregate information better than polls.
Order Book vs AMM Liquidity
A central limit order book (Kalshi’s model) matches real buyers and sellers with price-time priority, ideal for deep, regulated markets. An AMM (early Polymarket’s model) prices trades from a liquidity pool formula such as CPMM or LMSR, ideal for long-tail markets that need instant liquidity.
Oracle-Based Settlement
Markets are only as trustworthy as their resolution. Decentralised platforms use optimistic oracles such as UMA, where a proposed outcome stands unless disputed. Centralised platforms use named settlement sources, evidence archives and human review queues with dispute windows.
Market Design & Question Writing
Ambiguous questions destroy platforms. Every market needs one precise question, a named settlement source, exact expiry conditions and edge-case rules written before listing. This editorial discipline is the least discussed and most important part of the category.

Representative Builds From Our Real-Money Platform Practice
Client names are withheld under NDA — exactly what you should expect from a vendor in this category. Full architecture walkthroughs and references are available on a call.
Event Contract Exchange for a US-Focused Fintech
A funded startup needed a Kalshi-style exchange with a CLOB engine, fiat rails and compliance tooling their counsel could defend. We delivered the matching engine, member portal, surveillance dashboards and a market-listing workflow in 22 weeks, then supported their regulatory submissions with technical documentation.
Polymarket-Style Platform for a Crypto Operator
An exchange group wanted on-chain event markets with outcome tokens, UMA-based resolution and gasless trading for mainstream users. We shipped audited contracts on Polygon, a hybrid liquidity design and a wallet onboarding flow that removed seed phrases from the first-trade journey entirely.
Sports Prediction App for a Media Brand
A sports media company needed engagement, not gambling exposure. We built a free-to-play prediction product with virtual currency, streaks, leaderboards and sponsor-funded rewards, integrated with their app and CMS, with a compliance structure that kept it clearly outside betting regulation.
Which Engagement Model Fits You? An Honest Comparison
Most agencies push whichever model earns them most. Here is the trade-off table we walk every prospect through — including the reasons not to choose each option.
How Prediction Market Platforms Make Money
We build monetisation into the architecture, not as an afterthought. These are the revenue levers we implement and tune for operators.
Trading Fees
Maker and taker fees on matched volume, or spread-based fees on AMM trades — the core engine of Kalshi-style revenue.
Settlement & Withdrawal Fees
Small fees on winning settlements or fiat and crypto withdrawals, configurable by region and payment rail.
Liquidity & Listing Revenue
Fees for third parties to list sponsored markets, plus revenue share with professional market makers.
Premium Subscriptions
Pro tiers with advanced analytics, API access, lower fees and early market access for power traders.
B2B Data & Odds Feeds
Licensing your live probability data to media, hedge funds and research desks — an underused high-margin stream.
White-Label Sub-Licensing
Once live, license your own platform to regional partners. We architect multi-tenant support from day one if you plan this.
Sponsorship & Promotions
Brand-sponsored markets and reward pools — the primary model for free-to-play and media deployments.
Interest on Float
Where lawful, yield on custodied balances and collateral, implemented with segregation and reporting controls.
The Stack Behind Our Prediction Market Builds
Chosen for latency, auditability and hiring reality — and always adapted to your team’s preferences rather than forced on you.
From First Call to Live Markets in Eight Disciplined Steps
Discovery & Compliance Mapping
Goals, jurisdictions, licence posture and model selection with your counsel involved early, not after the build.
Product Specification
Market taxonomy, feature scope, engine choice and a fixed, written specification you sign off before design.
UI/UX Design
Wireframes, design system and high-fidelity prototypes for every trader and admin screen, tested with real users.
Engine & Platform Build
Agile sprints with fortnightly demos covering the matching engine or contracts, APIs, apps and admin.
Audit & Hardening
Smart-contract audits, penetration testing, load testing to your projected peak and failover rehearsals.
Liquidity & Content Setup
Seed markets written with our playbook, market-maker configuration and launch promotions prepared.
Launch
Staged rollout, app-store submissions, monitoring dashboards live and a war-room for the first trading days.
Hypercare & Growth
90-day hypercare, then SLA support, feature sprints and conversion optimisation on a roadmap you control.
What a Prediction Market Platform Really Costs in 2026
Transparent ranges, because “contact us for pricing” wastes everyone’s time. Final quotes depend on engine choice, chains, jurisdictions and integrations — we itemise every line in our proposals.
Compliance Is a Feature, Not a Disclaimer
Prediction markets sit close to financial and gambling regulation, and the rules differ by country and by model. We are engineers, not your lawyers — but we build the controls your lawyers will ask for, and we have done it before.
Jurisdiction-aware architecture
Geofencing, region-specific market visibility, per-country payment rails and configurable restricted lists, controlled from the admin panel rather than hard-coded.
KYC/AML pipelines
Tiered verification, document and liveness checks, sanctions and PEP screening, transaction monitoring rules and SAR-ready reporting exports.
Regulated-model tooling
For exchange-style builds: position limits, market surveillance flags, member agreements, audit trails and the technical documentation packs regulators request.
Responsible-trading controls
Deposit limits, cool-off periods, self-exclusion and affordability signals — protections that increasingly decide licensing outcomes.
Sweepstakes & free-to-play structures
Where real-money trading is not available to you, we implement virtual currency and sweepstakes-compliant mechanics reviewed with your counsel.
Security by default
Independent smart-contract audits, penetration tests, SOC-style logging, encrypted PII and least-privilege admin access as standard, not add-ons.
Fourteen Things Most Prediction Market Vendors Never Mention
If a proposal you are comparing does not address these, you are looking at a clone script with a sales deck. Every item below is scoped explicitly in our statements of work.
Cold-start liquidity plan
Empty order books kill launches. We deliver seeding bots, market-maker configs and incentive budgets modelled before day one.
Question-writing editorial workflow
A drafting playbook and review queue so every market has a settleable question, a named source and edge-case rules.
Dispute & mis-resolution procedure
Documented dispute windows, evidence archives, rollback procedures and user communication templates for contested outcomes.
Fee & payout maths shown pre-trade
Traders churn when payouts surprise them. Our order tickets show fees, average price and max payout before confirmation.
Latency budgets in the contract
Matching and API latency targets written into the specification and load-tested, not promised verbally.
App-store approval strategy
Apple and Google treat prediction products unevenly. We plan review categories, regional builds and web fallbacks upfront.
Gasless & walletless onboarding
For Web3 builds, account abstraction and embedded wallets so mainstream users never see a seed phrase or gas prompt.
Data exhaust as a product
Probability feeds, embeddable widgets and an odds API architected in, turning your markets into a distribution channel.
Multi-outcome & scalar markets
Beyond Yes/No: categorical markets, ranges and index-style contracts, with the settlement maths handled correctly.
Ops runbooks & training
Written runbooks for resolution days, incident response and payment failures, plus recorded admin training for your staff.
SEO & content architecture
Market pages rendered for search and answer engines, structured data and programmatic landing pages so markets acquire their own traffic.
Exit-friendly engineering
Documented code, infrastructure as code and escrow options, so you are never hostage to your vendor — including us.
Realistic legal boundaries
We say plainly what requires a licence, what does not, and where free-to-play is the honest route — before you spend.
Post-launch growth loop
Referrals, streaks, notification strategy and retention analytics designed into v1, because launch day is the start, not the finish.
