Practice the decision.
Keep the bankroll simulated.
Use live Kalshi reference books to rehearse forecasts, entries, sizing, and review without sending an order to the venue.
01
What is Kalshi paper trading?
Kalshi paper trading means practicing decisions on Kalshi event contracts with simulated money instead of placing an order at the venue.
A useful paper-trading record preserves the parts of the decision that determine whether an idea could survive live execution: the contract and side, the quoted bid and ask, the time, intended size, modeled fill, applicable fee assumption, exit or settlement, and the reason for the trade. Merely writing down the latest displayed probability after the fact is not a test.
Refract Funding provides a free simulated environment that references live Kalshi and Polymarket market data. User orders remain inside Refract Funding; they are not sent to Kalshi. That makes the tool useful for rehearsal, journaling, and evaluation, but a simulated result is not proof that an identical live order would fill.
Refract Funding is independent of Kalshi and Polymarket. It uses their published market data as a simulation reference and does not send user orders to either venue.
02
A six-step practice loop
The point is not to manufacture a green balance. It is to make a forecast before the outcome and preserve enough context to audit it.
- Read the contract and resolution source. Write down exactly what must happen for Yes to settle at $1 and note the deadline, timezone, and edge cases.
- Record your probability before seeing your desired entry. A forecast of 58% is testable; “I like Yes” is not.
- Inspect the book. Compare your estimate with executable prices, not only the last trade or midpoint.
- Choose a limit and size. Decide the worst price you will accept and cap the loss before submitting the simulated order.
- Define the review trigger. State whether you intend to hold through settlement or re-evaluate when named evidence changes.
- Score the process. Review forecast calibration, entry quality, execution, sizing, and rule interpretation separately from profit.
New traders can use the Kalshi trading strategies guide to turn this loop into a repeatable research and review process.

Worked example: probability is not the same as entry price
A forecast can be directionally right and still be a poor trade if the price already reflects it.
Suppose a contract's displayed book is 46¢ bid and 49¢ ask for Yes. Your independently documented estimate is 55%. Buying 100 Yes contracts immediately at 49¢ creates a gross simulated cost of $49 before any modeled fees. If the contract settles Yes, the gross settlement value is $100 and the gross gain is $51. If it settles No, the gross loss is the $49 cost.
| Input | Recorded value | Why it matters |
|---|---|---|
| Your estimate | 55% | The forecast to evaluate later |
| Displayed book | 46¢ bid / 49¢ ask | The immediate executable reference |
| Simulated order | Buy 100 Yes at 49¢ limit | Fixes size and maximum entry |
| Gross risk | $49 before modeled fees | Maximum contract cost in this example |
| Estimated edge | 6 percentage points before costs | 55% estimate minus 49¢ entry |
That six-point difference is not a guaranteed profit. Your estimate may be wrong, the available quantity may be smaller than 100, the quote may move, and costs reduce the margin. A good journal records each of those assumptions instead of treating the eventual outcome as the only verdict.

What makes a simulator useful
- Timestamped reference prices. The exercise should preserve what the market showed when the decision was made.
- Bid, ask, and available depth. A midpoint is not automatically available to a buyer or seller.
- Limit-order behavior. An unfilled order is information, not permission to award a better price retrospectively.
- Costs stated explicitly. Fee schedules can change; a practice tool should identify whether and how it models them.
- Resolution fidelity. The contract's official rules and source decide settlement, not the trader's interpretation of the headline.
- Complete history. Losing, canceled, partially filled, and unresolved attempts belong beside winners.
Simulations still have limits. Latency, queue position, data gaps, venue controls, and rapidly changing depth can make a real fill differ materially. Treat paper results as evidence about a process, never as a promise of future returns.
05
From free practice to a Refract Evaluation
Free practice and the paid Evaluation use simulated accounts, but they serve different purposes.
| Feature | Free simulator | Evaluation |
|---|---|---|
| Purpose | Learn and test a process | Demonstrate performance under published rules |
| Payment | No Evaluation purchase required | One-time entry fee per attempt |
| Account | Simulated | Simulated |
| Rules | Practice at your pace | Profit target, drawdown, consistency, and review |
| Outcome | Experience and journal data | Passing may lead to funded review; never guaranteed |
Read the complete rulebook before purchasing an Evaluation. A profitable practice record does not guarantee that an Evaluation will pass or that funded access or a payout will be approved.
This material is educational, not investment advice. No strategy or hypothetical example guarantees a profit. Trading, balances, positions, and fills on Refract Funding are simulated.
06
Verify the live rules before you practice
Venue mechanics, eligibility, market availability, and fees can change. Use Kalshi's official Help Center, API documentation, and the rules attached to the specific contract as the controlling sources. Refract's methodology and funded-program conditions are published in its rulebook, Terms, and Risk Disclaimer.
FAQ
Frequently asked questions
Can I paper trade Kalshi without a Kalshi account?
A third-party simulator can reference publicly available Kalshi market data without placing an order in your Kalshi account. Refract Funding's user trades are simulated and are not routed to Kalshi. Data coverage and availability may vary.
Is Kalshi paper trading the same as a funded account?
No. Paper trading is practice with simulated money. A Refract funded account is also simulated, but it follows a separate eligibility and review path and eligible simulated profits may qualify for conditional real USDC payouts under the program rules.
Do simulated profits predict live profits?
No. A simulator can test decisions and discipline, but real execution can differ because of latency, queue position, changing liquidity, fees, and trader behavior. Neither simulated nor historical performance guarantees future profit.
What should I record in a paper-trading journal?
Record the exact contract, resolution source, timestamp, probability estimate, displayed bid and ask, intended limit, available depth, size, modeled fees, thesis, invalidation trigger, fill, exit or settlement, and a post-trade process review.
Important: All trading, balances, positions, and fills on Refract Funding—including in the simulator, Evaluations, and funded accounts—are simulated. No real money is placed at risk in a simulated trade, although Evaluation fees are real payments. An Evaluation fee buys access to a skill challenge; it is not a deposit, investment, market stake, or trading capital. Refract Funding is independent of Kalshi and Polymarket; references to those venues do not imply endorsement.
Passing an Evaluation does not guarantee a funded account or payout. Funded access and payouts, where offered, depend on the program rules, eligibility, identity and fair-play review, regional availability, and approval. Market data and simulated results may be delayed, incomplete, or inaccurate. Refract Funding is not a broker, exchange, or investment adviser, and nothing on the service is investment advice. Adults 18+ only; additional age or location restrictions may apply.
