How to Use Kalshi: Sign-Up, Verification, First Trade (2026)

What you need before you sign up

As of September 18, 2026, Kalshi's account and verification help center says individual applicants must be at least 18 and pass document verification if requested. Kalshi describes international access subject to restricted jurisdictions in its Member Agreement. You are responsible for checking whether using the exchange is lawful for you; opening the website is not proof of eligibility.

For readers outside the United States, the help center says supported payment methods and phone numbers can depend on location. Check those constraints before treating a new account as ready to fund. The broader legal context is covered separately in our guide to arbitrage legality.

Creating your account step by step

If you are wondering how to sign up for Kalshi, separate account creation from approval. The Kalshi sign-up and contact-verification instructions checked as of September 18, 2026 describe this sequence:

1. Go to kalshi.com/sign-up and start an individual application.
2. Provide accurate personal information, including your legal name, date of birth, and residential address.
3. Verify your email using the code Kalshi sends. Check the address you entered and the spam folder if it does not arrive.
4. Verify your phone number using the SMS code. Not every international number is supported.
5. Complete the identity-verification prompts and supply additional documents when requested. Follow any review instructions sent by email or shown in your account.

As of September 18, 2026, Kalshi says it collects sign-up information "to comply with applicable U.S. laws and CFTC rules and regulations." Verification is part of opening the account, rather than a promise that approval will follow any particular submission. Check the account's actual status before planning to use it for a trade.

Use the same sign-in method when returning to your account, and keep access to the registered email and phone. If a code is delayed, follow the current help instructions instead of repeatedly changing the information you supplied. Make a note of the exact error and contact official support if the flow remains blocked.

Passing identity verification

Kalshi verification is easier to follow when your profile and documents agree.

As of September 18, 2026, Kalshi's document and account-verification guidance lists an original government-issued photo ID, such as a valid driver's license or passport, when documentation is requested. It must be unexpired, undamaged, and legible. When prompted, photograph the physical ID directly through the verification flow; the guidance rejects camera-roll uploads, screenshots, and pictures of another screen.

The matching rules are specific:

• Enter your name and date of birth exactly as they appear on the ID, including a middle name where shown.
• Use your physical residential address, not a commercial address or PO box.
• If your legal name has changed, provide the official change documentation needed to update the account.

As of September 18, 2026, the help center also says further documents, such as proof of address, employment information, or source of funds, may be required. Respond to the actual request through the official account flow. Do not send identity documents to someone who contacts you privately claiming they can accelerate approval.

If verification fails, retake the image with even lighting, no glare, all four corners visible, and readable text. Check that the ID is valid and that your profile matches it. If those steps do not resolve the issue, contact Kalshi support through in-app chat. Creating another account does not correct the mismatch in the original application.

The document-verification article checked as of September 18, 2026 describes a typical short process, but that is not a fixed approval deadline. Additional review can still be required. Wait for the account's confirmation before assuming that deposits and trading are enabled.

Depositing funds

Before making a Kalshi deposit, confirm that your account is approved and that you can use the selected payment method.

As of September 18, 2026, Kalshi's deposit help center documents the following methods. Availability depends on your account and region:

• Debit card, including supported wallet-payment options; check card compatibility in the flow.
• Bank transfer through ACH, available for US accounts.
• Wire transfer, available for US and international accounts; use the account-specific memo and instructions.
• Crypto, using a supported asset and network through the applicable transfer provider.
• Cash App, available for US users for deposits.
• PayPal, for eligible US users; availability can vary by state.
• Venmo, for eligible US users; availability can vary by state.
• Real-time payments, or RTP, from a participating US bank, with the required account-specific memo.

As of September 18, 2026, debit, Cash App, PayPal, Venmo, and crypto transfers can carry charges, while the help center describes ACH and wire deposits without an additional Kalshi charge and RTP without an added Kalshi charge; providers or banks may still charge. Review the Kalshi fee schedule and the selected method's current confirmation screen before authorizing the transfer. This is a funding check, not a reason to choose a method solely because it appears faster.

As of September 18, 2026, Kalshi describes RTP arrival within minutes, with possible delays in balance updates during end-of-day processing. Its help center also publishes timing guidance for other methods, so RTP is not the only method with a stated timeframe. Check the selected method's minimum and displayed limits before sending; do not apply a card minimum to a wire transfer.

For crypto, match both the asset and network before copying the destination. For wires and RTP, use your own memo from the Transfers page. Keep the transaction reference until the balance is credited. A transfer in progress and money available to trade are different states, so check the usable balance before opening the other side of a route.

Placing your first trade

Kalshi uses an order book for event contracts. Example, not a live quote: a YES price of 49 cents implies a roughly 49% market probability. One YES contract bought at that price costs $0.49 before applicable charges, pays $1 if YES wins under its rules, and pays $0 if NO wins.

Read the resolution source and the exact question before choosing a side. Review the quantity and acceptable price, submit the order, then check what actually filled. A displayed price does not mean that an unlimited quantity is available. If an order fills only partly, you have only the executed quantity, not the quantity originally requested.

You can hold to settlement or seek to sell earlier into available liquidity. An early exit may realize a gain or a loss; the example is not a forecast. Before using the account for a paired position, review reading a route before you trade and compare both contracts' wording and resolution rules.

Why arbitrage traders need a Kalshi account

A Kalshi account supplies one side of a route that may also involve Polymarket. Our guide to how to use Polymarket explains the separate US and global products; check which product a route uses. A verified account at one venue does not establish permission to trade the other contract.

Review the actual available balances on both platforms and the size offered at each price. If one side moves or only partly fills, revisit the calculation before proceeding. ArbLense displays route information, while you remain responsible for checking and executing both venue trades.
