Kalshi Promo Code ACTION for $25 Bonus (September 2026)

Kalshi's standard deposit minimum is $10 for most payment methods. For this offer, though, you'll need to complete $25 in qualifying trades before the bonus is triggered.

Looking for fees, available markets, platform features or a broader breakdown of how Kalshi works? See the full Kalshi review.

You can claim the offer through either the Kalshi app or desktop site. Just make sure ACTION is attached to your account before you make your first deposit.

1. Open Kalshi through any of the links on this page and create a new account.
2. Enter ACTION in the promo-code field during signup.
3. Complete Kalshi's identity verification.
4. Deposit funds. The standard minimum is $10, but you'll need enough available to complete $25 in qualifying trades.
5. Complete $25 in eligible trade volume within 30 days of opening the account.
6. Once your $25 bonus credit is issued, use it within seven days.

Missed the code during signup? Kalshi gives eligible users up to 72 hours after account creation to add one, as long as they haven't deposited yet. Once a code has been applied, you can't swap it for another.

You also don't need to use a sports contract to qualify. The $25 requirement can be completed in any eligible Kalshi Predictions market available to you.

💡 Expert Insights: “Make sure promo code ACTION is applied and verified on your account before making your first deposit, either during registration or within the 72-hour grace period. While the minimum deposit is $10, depositing at least $25 allows you to meet the qualifying trade requirement in a single transaction and potentially avoid duplicate payment fees. Also, keep an eye on the two deadlines: you have 30 days to complete the qualifying trading volume, while the $25 bonus credit must be used within seven days of being awarded.”

The latest Kalshi sign up bonus for September gives new users the chance to claim $25 in bonus credit after completing $25 in qualifying trades. If you're wondering whether a promo code is required, the answer is yes: Kalshi promo code  ACTION unlocks the current Trade $25, Get $25 welcome offer.

💡 Expert Insights: "When I claimed the Kalshi sign-up bonus, which is the Trade $25, Get $25 offer, I completed the $25 qualifying requirement by buying a YES position on the Baltimore vs. St. Louis matchup. The $25 bonus was then added to my account immediately, allowing me to start trading with those funds right away, with no additional hidden requirements."

Kalshi looks at how much you've traded, not whether your qualifying position wins.

Once you reach $25 in eligible trade volume during your first 30 days, you qualify for the $25 credit. You don't need to wait for the qualifying position to resolve before hitting the volume requirement.

Here's how the credit works once it's in your account:

The $25 arrives as trading credit, meaning you can't withdraw it untouched. After you trade an amount equal to the credit, eligible profits can be withdrawn.

Lastly, once the $25 bonus credit is added to your account, you have only seven days to use it. If you're close to qualifying, check the available markets first so you don't trigger the credit when there are no markets you want to trade.

Before depositing, check that ACTION is showing on your account. If the code isn't there or the bonus doesn't track, save a screenshot of the offer and contact Kalshi support through chat.

We recommend you include the screenshot and explain when you signed up and completed the qualifying trades so support can review the issue and apply any missing credit, if appropriate, faster.

Kalshi asks for more upfront trading than some competing prediction market offers. Polymarket and Novig currently start with a $10 deposit, while ProphetX requires a $10 trade. DraftKings Predictions, on the other hand, has the lowest qualifying trade of the group at $5.

Here's how the current offers compare:

Keep in mind prediction market promos can change quickly, so check each offer's term and conditions before signing up.

You can compare more current offers on the prediction market promo codes page.

A few rules are especially easy to miss, including the 72-hour window for adding a forgotten code and the seven-day expiration once the credit is issued.

Official terms: Certain limitations apply. The offer is available to new users only, subject to the terms and conditions. 18+ only. Restrictions and eligibility requirements apply. Event contract trading involves significant risk and is not appropriate for everyone. Please carefully consider if it is appropriate for you in light of your personal financial circumstances. Kalshi products are not available in all jurisdictions. See kalshi.com/regulatory for more information. Not available in AZ, IL, MA, MD, MI, MT, NV, OH, and WA.

After claiming the Kalshi $25 bonus, you will immediately be able to trade on all available Kalshi markets including: sports, politics and elections, economics and financial, entertainment and culture, weather and perpetual futures.

💡 Expert Insights: "I'm a big NFL fan, so I used my $25 bonus on the Steelers vs. Bills preseason matchup tonight. I looked at the spreads and total market, chose 36.5 points as the baseline, and bought the Over in YES shares at 42¢, giving me a potential maximum payout of $57.19."

Promo eligibility and access to sports contracts aren't always identical. If sports markets are restricted where you are, you can still meet the $25 offer requirement through another eligible Kalshi market available in your location.

For state-specific coverage, see the Kalshi pages for Florida, California, and Texas.

The reward is fixed at $25, so most of the decisions come down to avoiding unnecessary costs and making sure the credit doesn't expire before you use it.

• Check the deposit fee before choosing a payment method. RTP deposits usually arrive within minutes with no Kalshi fee. Debit card deposits are also instant but may include a 2% processing fee. ACH deposits have no Kalshi fee but can take up to five business days to settle. Your first PayPal or Venmo deposit is free; later deposits may cost up to 2%.
• Open limit orders don't count toward the $25 requirement until they fill. Unfilled orders haven't added to your qualifying trade volume, though eligible resting orders may still earn liquidity rewards in some markets. See this Kalshi's incentive programs guide for details.
• Remember the seven-day expiration. If you don't see a market you'd want to trade with the credit, there's no benefit to rushing through the $25 requirement just to start the clock.

If you're still getting used to contract prices and different order types, the beginner's guide to Kalshi covers the trading side in more detail.

Trade $25, Get $25! is a new-user offer, but existing Kalshi traders can still get rewards through referrals and trading incentive programs.

Kalshi's referral reward and requirements vary by offer. Check Menu → Referrals or your Rewards section for the current details.

The program allows up to 40 referrals and has a lifetime earnings cap. Your cap and progress can be found in the Rewards section.

Once a friend completes the required steps, the credit may post automatically. If not, claim it from the referral or Rewards area. Referral credits expire seven days after they're issued unless the offer states otherwise.

See the Kalshi refer-a-friend guide for more details.

💡 Expert Insights: "The Kalshi Refer-a-Friend program can be a great way to earn extra rewards, but timing is important. The seven-day window starts when your friend creates their account, not when they fund it or place a trade, so delays with verification can cause them to miss the deadline. Also, you must complete $25 in trades yourself before referral rewards become available. For both sides, liquid markets with tight spreads, such as daily MLB games, can make it easier to meet the requirements."

Kalshi also offers two incentive programs for eligible U.S. users.

The Liquidity Incentive Program rewards qualifying resting orders in eligible markets, even if they never fill. Kalshi currently lists it through January 1, 2027, but may change or end it earlier.

The Volume Incentive Program rewards completed trading volume during active periods. Your payout depends on your share of qualifying volume, and Kalshi currently lists it through September 1, 2027.

Check eligible market pages for active rewards. This Kalshi incentive programs guide explains the scoring and payouts.

Kalshi is also expanding its presence in baseball. In August 2026, the prediction market announced exclusive, multi-year partnerships with five MLB teams: the Los Angeles Dodgers, Atlanta Braves, Boston Red Sox, San Diego Padres, and San Francisco Giants.

The deals include in-stadium signage, digital and social promotions, radio integrations, and fan activations across the five franchises. New users watching games in these Kalshi-studded stadiums can use Kalshi promo code ACTION to claim their welcome bonus and start trading.

Kalshi might even roll out specific promos tied to these teams — stay tuned for updates from Action Network.

If you're already planning to trade at least $25 on Kalshi, there's little reason to skip ACTION. You can reach the requirement through one trade or several, and whether those positions win doesn't affect your eligibility for the $25 credit.

The seven-day expiration is the part we'd keep and eye on. If nothing on Kalshi interests you that week, triggering the bonus immediately can leave you rushing to use it before it disappears.

Also remember that the reward comes as credit, meaning you can't withdraw the $25 without trading it first.

A seven-day expiration can make it tempting to trade just to avoid losing the credit, but don't let the deadline push you into spending more than you normally would.

Kalshi offers trading breaks, voluntary self-exclusion and personalized funding caps if you want tighter limits on your account.
