How to self-exclude from Kalshi, Polymarket, Robinhood and other prediction markets

By Charlie G, a compulsive gambler in recovery. Facts checked October 19, 2026 against the official pages linked below. Not medical, legal or financial advice.

Kalshi, Polymarket, Robinhood and a handful of newer apps let you buy contracts on who wins tonight's game. They call it trading. If you're chasing losses, hiding it, or can't stop checking prices, it's doing the same damage a sportsbook does, so lock it out the same way. Your state's self-exclusion list probably won't do it for you, so this page goes app by app.

Before you start

• Sell or close any open positions you can. A position you're holding is a reason to open the app again on game day.
• Withdraw what's left in each account.
• Write down every app you've used, including ones you only opened once. You'll go down the list.
• If you can, ask someone you trust to sit with you while you do this. When I quit, I handed my accounts to people I trusted. It helped to not be alone with the screen.

Kalshi

1. Open Responsible Risk Management

   In the app: tap the menu icon, go to Settings or Account Options, then Responsible Risk Management. On the web: open the sidebar menu at the top left and scroll to Responsible Risk Management.

2. Choose self-exclusion

   Pick self-exclusion, not a trading break. A break is short. Kalshi doesn't list its term lengths on its help page, so choose the longest one the app shows you.

3. Confirm

   Kalshi says the exclusion covers its website, app and API. Any position you still hold stays open until it settles.

SelfExclude.io (covers several apps at once)

SelfExclude.io is a shared exclusion list for US prediction markets. You sign up once, and every connected app checks your status.

1. Create an account

   Start at selfexclude.io with your email.

2. Verify your identity

   You'll need your legal name, address, date of birth, phone number and a government ID. Verification is done by Veriff.

3. Pick 1 year

   The options are 1, 3, 6 or 12 months. Take 12. The site says partner apps apply the block within 24 hours, and you can't shorten it once it's set.

4. Set your renewal reminder

   The exclusion ends on its own when the term runs out. Put a reminder in your phone for a week before that date and re-enroll. A one-year limit is the site's rule, but nothing stops you renewing every year.

Who's connected (as of October 2026): Kalshi and Novig are fully connected. SelfExclude.io lists Polymarket, Robinhood, ProphetX, Matchbook and Juice Exchange as in progress, so exclude in those apps directly for now.

Polymarket US

• Polymarket's US app offers self-exclusion from one month up to one year, or permanently. Choose permanent.
• Polymarket says it takes effect as soon as you confirm. Find it with the other user protections in your Polymarket US account.
• Polymarket also offers deposit limits, but a limit still leaves the door open. Exclude.

Robinhood

Robinhood has an in-app switch that hides sports prediction markets. Robinhood's own help page says you can still trade sports contracts with that setting changed, so it isn't a block. Self-exclusion goes through support.

1. Close your event contract positions

   Robinhood needs them closed before your event contract account can be fully turned off.

2. Contact support in the app

   Ask for self-exclusion from all event contract trading. Say those words. Robinhood reviews the request, then removes prediction markets from your account after a short wait.

3. Get it in writing

   Keep the confirmation message. To turn event contracts back on, you'd have to contact support and go through a review, which gives you time to call someone first.

4. Turn off the alerts

   Account, then Notifications, then Event contracts. Switch them all off.

Coinbase

Coinbase's help page shows a switch to turn Predictions off: menu, Account & Settings, Predictions, then switch it off and tap Shut off. You can switch it back on just as easily, so don't stop there.

• Contact Coinbase support from the Help section and ask them in writing to restrict your account from prediction markets.
• Sell any open contracts and cancel open orders, then ask to close your predictions account.
• Keep whatever they send you in writing.

Fanatics Markets

• Self-exclusion is in the profile section of the app. It lasts at least 1 year.
• Fanatics says your remaining funds are returned and any open positions are closed out automatically when you exclude.
• Fanatics Markets is a separate app from Fanatics Sportsbook. If you used both, exclude from both.
• Questions: [email protected]

DraftKings Predictions, FanDuel and other sportsbook-run apps

DraftKings Predictions is its own app, separate from the DraftKings Sportsbook. DraftKings says it offers self-exclusion, cool-offs and deposit limits through its Responsible Trading Center inside the app. Your DraftKings Sportsbook exclusion is a separate thing, so do this one too.

FanDuel and other big sportsbook brands have launched their own prediction apps as well. Open each app's responsible trading or account menu, find self-exclusion, and pick the longest term. If you can't find it, ask support for self-exclusion by name and get the answer in writing.

Does my state's self-exclusion cover these apps?

Probably not. These apps are regulated by a federal agency, the CFTC, as financial contracts. State self-exclusion lists are run under state gambling law and cover state-licensed sportsbooks, casinos and lotteries. Don't count on your state list to reach a prediction market app.

Do both. Enroll in your state's program, at lifetime if it's offered, and exclude inside every prediction app. Find your state's program on your state page.

Then lock the doors

• Delete the apps and block them with BetBlocker or Gamban, plus your phone's own settings on iPhone or Android.
• Remove saved cards and bank links from every app. These apps are set up as trading accounts, so a card's gambling block may not catch the deposits. Read our bank blocking guide.
• Exclude from any sportsbook and fantasy apps you've used too. Here's PrizePicks and Underdog.

These tools buy you time. I'm still the last line of defense between me and the next bet, and you are for yours. Use the time they give you to build the rest: people you're honest with, a meeting, a plan for the hard nights.
