If you need to block Polymarket, Kalshi, or other prediction market platforms, you’re not alone — and you’re not overreacting. Prediction markets are rapidly becoming the newest form of compulsive gambling, and they’re slipping through every traditional safeguard. Self-exclusion programs don’t cover them. Most gambling blockers don’t flag them. And because they brand themselves as “forecasting tools” or “event contracts,” many people don’t even realize they’ve developed a gambling problem until the losses are devastating.
This guide explains exactly how to block Polymarket, Kalshi, and similar prediction betting platforms on every device — and why these sites are uniquely dangerous for people prone to gambling addiction.
What Are Polymarket and Kalshi?
Before covering how to block them, it helps to understand what these platforms actually are — because their marketing deliberately blurs the line between investing and gambling.
Polymarket is a crypto-based prediction market where users bet on the outcomes of real-world events — elections, economic data, sports, celebrity news, geopolitics, and more. You buy “shares” in an outcome using cryptocurrency (primarily USDC on the Polygon blockchain). If your prediction is correct, you earn a payout. If it’s wrong, you lose your stake. Despite calling itself a “prediction market,” the mechanics are identical to sports betting: you’re wagering money on uncertain outcomes.
Kalshi is a CFTC-regulated prediction market based in the United States. Unlike Polymarket, Kalshi operates with US dollars and is legally authorized to offer “event contracts.” You can bet on everything from Federal Reserve interest rate decisions to weather events to whether a particular bill will pass Congress. Kalshi’s regulatory status gives it an air of legitimacy that makes it even more dangerous for problem gamblers — it feels like finance, but it triggers the exact same dopamine pathways as a casino.
Other prediction market platforms include PredictIt, Metaculus (which is non-monetary), Manifold Markets, and various decentralized alternatives built on Ethereum and Solana. The space is growing rapidly, and new platforms appear regularly.
Why Prediction Markets Are a Hidden Gambling Problem
Prediction markets exploit a dangerous psychological blind spot: people who would never walk into a casino or open a sports betting app will happily wager thousands on Polymarket because it feels intellectual. You’re not “gambling” — you’re “predicting” or “investing in outcomes.” This reframing is exactly what makes prediction markets so addictive for a specific type of person.
The intellectual disguise. Prediction markets attract people who consider themselves analytical and informed. Every bet feels like a rational decision backed by research. But the causes and signs of gambling addiction don’t discriminate based on how smart the gambler thinks they are. The dopamine hit from a correct prediction is chemically identical to the dopamine hit from a winning slot pull.
24/7 markets with constant triggers. Unlike traditional casinos or even sports betting (which at least has an off-season), prediction markets run continuously. Every news headline becomes a potential bet. Election polls, economic reports, Fed meetings, tech earnings, court rulings — the entire news cycle becomes a gambling trigger. If you’re prone to compulsive betting, prediction markets turn your entire media consumption into a minefield.
Social validation and FOMO. Polymarket and Kalshi positions are widely shared on social media, especially X (Twitter) and Reddit. Seeing others post their winning bets creates intense fear of missing out. “I knew that was going to happen — I should have bet on it” becomes a recurring thought pattern that drives compulsive participation.
No responsible gambling features. Polymarket has virtually no responsible gambling infrastructure — no deposit limits, no self-exclusion, no loss limits, no reality checks. Kalshi offers slightly more (being CFTC-regulated), but its responsible gambling tools are minimal compared to licensed sportsbooks. Neither platform is covered by GamStop or any state self-exclusion registry.
How to Block Polymarket and Kalshi on Every Device
Because prediction markets don’t appear on traditional gambling blocklists, blocking them requires a deliberate, multi-layered approach. Here’s how to do it effectively:
Step 1: Install Bet Breaker and Add Custom Blocks
Bet Breaker blocks over 200,000 gambling sites and apps — and critically, it lets you add custom domains. This is essential for prediction markets because many traditional blockers don’t categorize them as gambling. After installing Bet Breaker, immediately add these domains to your custom blocklist:
- polymarket.com
- kalshi.com
- predictit.org
- manifold.markets
- gamma.polymarket.com (Polymarket’s trading interface)
- Any other prediction platform you’ve used
Bet Breaker’s anti-uninstall protection ensures these blocks stay in place even during your worst moments. This is non-negotiable for prediction market addiction — without tamper-proof blocking, your analytical brain will rationalize removing the blocker because “this isn’t really gambling.” For a deeper look at how blockers work, see our guide on how gambling blockers work.
Step 2: Remove Crypto Wallets and Close Accounts
For Polymarket specifically, you need a crypto wallet to participate. Remove MetaMask, Coinbase Wallet, Phantom, and any other browser wallet extensions. Move any USDC or cryptocurrency you’ve been using for prediction markets to cold storage (a hardware wallet) and give the recovery phrase to a trusted person.
For Kalshi, log into your account and request permanent account closure — not just deactivation. Remove your payment methods first. If you’ve linked a bank account, contact your bank about blocking transactions to Kalshi’s merchant ID. The more friction you create between your money and these platforms, the safer you are. For more on this approach, our article on blocking crypto casinos covers the financial control strategies in detail.
Step 3: Block Prediction Market Content on Social Media
This step is critical and often overlooked. Social media is the number one trigger for prediction market gambling because every trending news story gets paired with Polymarket odds or Kalshi contracts. Here’s how to reduce exposure:
On X (Twitter): Mute the words “Polymarket,” “Kalshi,” “prediction market,” “event contract,” and any prediction market accounts you follow. Unfollow accounts that regularly share prediction market positions. Use the “Not interested in this” option on prediction market posts to train the algorithm away from showing you this content.
On Reddit: Unsubscribe from r/Polymarket, r/Kalshi, r/PredictionMarkets, and any related subreddits. Use Reddit Enhancement Suite (RES) to filter posts containing prediction market keywords.
On YouTube and podcasts: Click “Don’t recommend channel” on any content creator who discusses prediction market bets. Avoid political or financial commentary shows that regularly reference Polymarket odds — these have become normalized triggers for many people.
Step 4: Set Up DNS-Level Blocking
Add another layer by blocking prediction market domains at the network level. Change your home router’s DNS to a filtering provider like CleanBrowsing or OpenDNS, then create custom rules to block polymarket.com, kalshi.com, and related domains. Have a trusted person set the router password so you can’t undo this during a weak moment.
On your phone, use a DNS-filtering app that allows custom blocklists. This catches prediction market traffic from any app or browser on your device — including mobile apps you might not have thought to block individually.
Step 5: Tell Someone and Build Accountability
Prediction market addiction thrives in secrecy — partly because it’s so easy to hide behind the “I’m just investing” narrative. Breaking that secrecy by telling a trusted friend, family member, or therapist is one of the most powerful steps you can take. Bet Breaker’s Sponsor Mode ensures someone you trust gets notified if you try to disable protection, creating the external accountability that prediction markets deliberately eliminate.
If you’re not ready to tell someone in your personal life, the Bet Breaker recovery community offers anonymous peer support from people who understand compulsive betting — including those who’ve struggled with prediction markets specifically.
Signs You Need to Block Polymarket or Kalshi Right Now
If you’re reading this article, you probably already suspect you have a problem. But prediction market addiction is easy to minimize because it feels so different from “real gambling.” Here are the warning signs that should prompt immediate action:
You check Polymarket or Kalshi positions multiple times per day. You consume news primarily through the lens of “how will this affect my bets.” You’ve lost more money than you planned and told yourself you’ll win it back on the next event. You feel anxiety or excitement about upcoming news events because of your open positions. You hide your prediction market activity or losses from your partner or family. You’ve moved money from savings, investments, or crypto holdings into prediction market accounts. You’ve tried to stop or cut back and couldn’t. You justify your betting as “research” or “informed forecasting” despite consistent losses.
If any of these resonate, this is gambling addiction — regardless of what label the platform uses. The mechanisms, the compulsion, the financial damage, and the emotional toll are identical. And the solution starts with the same first step: cutting off access immediately.
Frequently Asked Questions
Are prediction markets like Polymarket actually gambling?
Yes, by any functional definition. You’re wagering money on uncertain outcomes with the possibility of losing your entire stake. The fact that prediction markets brand themselves as “forecasting” or “event contracts” doesn’t change the underlying mechanics. Polymarket operates identically to a crypto sportsbook, and Kalshi’s event contracts function the same way as binary options — which many countries have banned as a form of gambling. If it triggers compulsive behavior and financial losses, the label doesn’t matter.
Why don’t regular gambling blockers block Polymarket and Kalshi?
Most gambling blockers maintain lists of known gambling domains — traditional casinos, sportsbooks, and poker sites. Prediction markets are relatively new and often classified as “financial services” rather than gambling. This classification gap means platforms like Polymarket and Kalshi fly under the radar. Bet Breaker solves this problem with custom blocking — you can add any domain immediately, regardless of how it’s categorized.
Is Kalshi legal? Does that mean it’s safe?
Kalshi is CFTC-regulated and legally authorized to operate in the United States. But legal doesn’t mean safe for people with gambling tendencies. Alcohol is legal too — that doesn’t make it safe for someone with alcohol dependency. Kalshi’s regulatory status actually makes it more dangerous in some ways because it provides a veneer of legitimacy that makes it harder to recognize compulsive use as a gambling problem. The regulatory framework doesn’t include the responsible gambling protections found in licensed sportsbooks.
Can I use prediction markets recreationally without developing a problem?
Some people can, just as some people can gamble recreationally without developing an addiction. But if you’re reading an article about how to block these platforms, that’s a strong signal that recreational use isn’t working for you. The honest answer: if you need to block prediction markets, block them completely. Moderation rarely works with gambling addiction because the compulsion reactivates with every bet. Total abstinence supported by external barriers is far more effective than trying to set limits you’ll inevitably override.
