Build your understanding.
Start with a claim and its rules. Then examine cost, product choice and the tools supporting your research.
A beginner’s path
- What is a prediction market? →
A market for contracts tied to defined outcomes. Its prices can express expectations, while its rules determine what eventually gets paid.
- How Kalshi works: from a contract price to settlement →
A contract has a price today and a defined payoff later. Understand the question, your total outlay and the loss scenario before interpreting its implied probability.
- Polymarket US vs international: two separate products →
Identify the venue before reading a market, funding an account or comparing a fee. US dollars and international crypto balances are not interchangeable.
- Kalshi fees: formulas, funding and a full trade example →
The published schedule separates general taker charges, market-specific maker charges, settlement and funding. Here are the numbers and their limits.
- Kalshi payout calculator: payout is not profit →
Calculate stake, total outlay and winning/losing settlement results. Enter the fee actually quoted; compare the raw general formula separately.

Explanations
How Kalshi works: from a contract price to settlement
A contract has a price today and a defined payoff later. Understand the question, your total outlay and the loss scenario before interpreting its implied probability.
How Polymarket works: US and international explained
The two products share a brand but differ in account structure, funding, fees and access. Here is how to read each without mixing them together.
What is a prediction market?
A market for contracts tied to defined outcomes. Its prices can express expectations, while its rules determine what eventually gets paid.
Kalshi payout calculator: payout is not profit
Calculate stake, total outlay and winning/losing settlement results. Enter the fee actually quoted; compare the raw general formula separately.
Polymarket US vs international: two separate products
Identify the venue before reading a market, funding an account or comparing a fee. US dollars and international crypto balances are not interchangeable.
Comparisons
Kalshi vs Polymarket US: costs, funding and rules
Both use event contracts, but the full comparison includes product identity, order execution, funding and exceptional settlement.
Novig vs Kalshi: sports focus, fees and settlement
Novig’s game/futures schedules and Kalshi’s series multipliers differ. Compare the same payout units and event definitions before comparing cost.
Product guides
Kalshi: a source-based product guide
A broad event-contract venue with a price-dependent fee schedule. Best understood through contract rules, order type and total outlay.
Polymarket US review: dollar accounts, funding and contract costs
A documentation-based assessment of the US product: what identity checks precede trading, how cleared withdrawals work, and what a standard contract costs. International wallet instructions do not apply.
Novig v3 fees and game settlement: quantity units explained
Understand one-cent payout units, live-game versus futures charges, order transitions and push/FMV grading. Consumer access, age and banking terms remain specifically unresolved.
Polymarket international: mechanics and US access limits
A separate crypto-based event-market product, explained for context rather than offered as a US trading route.
IBKR Prediction Markets: broker access and the venue distinction
Interactive Brokers presents prediction markets within a broader brokerage. The broker interface and the underlying contract venue are separate parts of the comparison.
Event definitions
Fed decision contracts explained: dates, basis points and settlement
Understand how a meeting-date contract differs from a target-rate level or annual cut count. Official dates and a hypothetical calculation explain the mechanics; current odds are not displayed.
2028 election contracts explained: nominee, popular vote and electoral outcome
Distinguish the election claim before interpreting a quote. This is a contract-definition and resolution guide, with an illustrative payoff rather than current candidate odds.
CPI release contracts: reference period, rounding and revisions
CPI describes consumer price changes, but a contract must name the index and comparison. Headline all-items and core excluding food/energy differ; month-over-month and year-over-year are different calculations. Seasonally adjusted and unadjusted series can produce different observations.
Employment report contracts: payrolls, unemployment and revisions
The Employment Situation combines payroll employment and household-survey measures. Nonfarm payroll change and the unemployment rate answer different questions; a contract naming one cannot be evaluated from a headline about the other.
Understand the full cost, not just the fee
Fee guides
Kalshi fees: formulas, funding and a full trade example
The published schedule separates general taker charges, market-specific maker charges, settlement and funding. Here are the numbers and their limits.
Polymarket fees: the US and international schedules
US standard taker fees, market exceptions, maker rebates and international coefficients belong in separate columns.
Compare spot interfaces and complete costs
Comparisons
Kraken vs Coinbase: compare the spot products
Kraken publishes a numeric Pro schedule. Coinbase Advanced directs customers to their account-specific fee tier. Simple purchase pricing works differently on both.
Gemini vs Coinbase: spot costs and account workflows
Compare Gemini ActiveTrader with Coinbase Advanced, and keep simple-purchase charges separate from order-book trading.
Crypto.com App vs Coinbase: compare the final spot quote
Two simple-purchase workflows need a quoted-price comparison. Exchange and Advanced schedules answer a different question.
Kraken vs Kraken Pro: choose the spot interface
A simple purchase quote and a configurable order book solve different tasks. Compare the account relationship, controls and complete cost, keeping derivatives outside this spot decision.
Fee guides
Coinbase fees: simple buys, Advanced and withdrawals
Simple purchases include spread and quoted fees. Advanced uses an order book and account-specific tiers. Network sends and cash movements add separate costs.
Kraken fees: instant purchases versus Pro spot
The reviewed schedule lists instant trading fees, Pro tiers, spread and funding separately. Here is how to put them on the same basis.
Compare spot fees with Cost Lens
Compare execution, spread, funding and withdrawals for the same spot trade. Source presets and your assumptions stay clearly labelled.
Product guides
Crypto.com App: buying, funding and product boundaries
The App, Exchange, card and other Crypto.com products have separate workflows and costs. A single brand does not make their pricing interchangeable.
Kraken spot: interfaces, cash funding and limits
Instant purchase and Pro spot have different pricing. Compare the published execution rate with the funding route and withdrawal hold.
Coinbase spot: simple purchases and Advanced
Choose the interface before interpreting a quoted fee or spread. Payment capabilities and network-send charges remain separate.
Gemini spot: ActiveTrader and transfer costs
An explicit ActiveTrader tier table helps distinguish execution cost from bank, card and network transfers.
Choose software by the research job
Product guides
KalshiSpy: what its public product actually offers
An independent Kalshi analytics service advertising trader consensus, position grouping and alerts. Inspect the evidence behind the signal before treating it as a forecast.
OddsJam Prediction Traders: signals, venue scope and pricing limits
A public-feature guide to Prediction Traders, separate from sportsbook tools. Named venues and exit alerts are documented; paid delivery performance and the prediction-specific checkout price remain unverified.
CoinStats Polymarket integration: identify the account before syncing
The public integration list names Polymarket, but does not establish Polymarket US compatibility or complete imports. Understand the supported-account question before relying on a consolidated portfolio.
Prepare crypto records before buying a tax report
Product guides
CoinLedger: crypto imports, report pricing and limits
A crypto portfolio and tax-report product with documented exchange/API and CSV workflows. Paid report coverage is separate from a free import.
Koinly: tax-year plans and a reconciliation workflow
Koinly supports exchange/API and file imports, a free preview and paid tax-year reports. The useful question is whether your full history reconciles.
Compare hardware models and compatibility
Product guides
Trezor Safe 3 vs Safe 5: screen, compatibility and recovery
A dated model comparison from official specifications: two-button Safe 3 versus touchscreen Safe 5, with supported-system and backup limits. No device test or security audit is claimed.
Ledger Flex vs Stax: screen, price and custody tradeoffs
A source-based comparison of the $249 Flex and $399 Stax prices cited by Ledger, their E Ink screens and charging differences. Model compatibility and recovery remain separate checks.
Match chart and alert requirements to a plan
Product guides
TradingView: charts, alerts and subscription scope
A charting workspace whose plan limits and data entitlements should match your research routine.
TrendSpider: charting, scanning and strategy research
The official support catalogue describes an integrated charting and strategy-development workflow. Evaluate features separately from claimed trading outcomes.
TrendSpider pricing: capacity, cash due and renewal
Separate plan capacity, billing commitment, trial conversion and later renewal. Use dated plan evidence and a quote-based cost worksheet rather than an invented universal sale.
TradingView plans: capacity, annual cost and data entitlements
Choose the lowest documented capacity meeting your chart and alert task. Keep free access, prepaid annual cost, true monthly billing, renewal and market data separate.
