BLOCK KALSHI.
Untilt blocks Kalshi on your iPhone with Apple's Screen Time technology — the app and website stop loading while a wall is up. This matters more than it sounds: Kalshi is a federally regulated prediction market, not a state-licensed sportsbook, so state gambling self-exclusion programs don't cover it at all. If sports event contracts have become your action, the state list can't help you. The device wall can.
What Kalshi's own tools offer
Kalshi operates under CFTC oversight as a designated contract market — a financial exchange, not a casino. The state responsible-gaming apparatus (exclusion lists, gaming commissions) was never built to apply to it.
In 2026 Kalshi announced a self-exclusion initiative with IC360 — a genuine step, and worth using if you have an account. It remains account-level: it closes your access to Kalshi, on Kalshi's side.
Account tools close the account. Not the phone.
Sports event contracts are functionally sports bets for the person holding the phone — same games, same sweat, same 11 PM chase. The legal category changes the regulator; it doesn't change the reflex.
Untilt treats prediction markets as what they are on this phone: action. Kalshi's domains ship in the default blocklist next to DraftKings and FanDuel — one wall over the whole spectrum. Almost no other blocker covers this ground.
| Screen Time | Delete the app | Kalshi account tools | Untilt wall | |
|---|---|---|---|---|
| Blocks the app | Limit only | Until reinstall | No | Yes, while up |
| Blocks the website | Partially | No | No | Yes, while up |
| You hold the override | Your passcode | Reinstall | Locked for the term | Not mid-wall |
| Covers other books too | Per-app setup | No | No | Every covered book at once |
| Requires an account | No | No | Yes | No |
Three ways to block Kalshi on iPhone
1 · DIY Screen Time. Free and built in: set an app limit or block the website under Settings → Screen Time. The honest part: you know your own passcode, "Ignore Limit" is one tap, and web workarounds are endless. It's a speed bump you own the keys to. Full walkthrough in why Screen Time alone isn't enough.
2 · Delete the app + restrict downloads. Deleting Kalshi helps for a night — until a two-minute reinstall. Pairing it with Screen Time's purchase restrictions is stronger, but the website still loads, and the restriction shares that same passcode problem.
3 · A timed, maintained wall (Untilt). Untilt uses the same Apple Screen Time technology — without handing you the keys. One hold walls off a maintained set of 50 wagering apps and 50 gambling sites on this iPhone — Kalshi's app and website together, alongside every other covered operator — until the end time you chose. Walls are timed: free 1-hour walls forever, longer with Pro, and mid-wall there is nothing to toggle off. No account, no card, and everything runs on the device.
60-second setup
Install Untilt, allow Screen Time when iOS asks (one permission, one time — blocking is applied on-device, and Untilt cannot read your activity), then press and hold for two seconds. The wall goes up and Kalshi stops loading until the end time on the readout. When it matters most — mid-tilt, before the game, the moment the deposit urge hits — the whole ritual is one hold.
Questions
I self-excluded from every sportsbook in my state. Why can I still trade sports on Kalshi?
Because Kalshi isn't a sportsbook under state law — it's a federally regulated exchange. State exclusion lists have no jurisdiction over it. That's precisely why a device-level wall matters if event contracts are your version of the action.
Does blocking Kalshi block other prediction markets too?
Polymarket is covered by default as well. If a prediction-market surface loads while a wall is up, tell us at support@tryuntilt.com — coverage updates ship with the app.
Isn't Kalshi trading, not gambling?
On paper it's a regulated derivatives exchange. If you're reading this page, you already know what it is for you. The wall doesn't arbitrate — it just holds.
Does this block the website too, or just the app?
Both. A wall blocks the covered apps and the covered websites together — Kalshi's app and its domain are each in the maintained catalog, and Apple's Screen Time technology enforces both on this iPhone.
Does it work on cellular, or only Wi-Fi?
Both. The block is applied on the iPhone itself, so it holds on 5G, LTE, and any Wi-Fi network without router changes.
Can I take the wall down early?
Free walls run one hour and then come down on their own. Ending a long wall early is deliberately slow — a 24-hour wait, then a 15-second hold. Untilt never claims to be impossible to bypass; iOS gives the phone's owner final control. It claims to make the next bet slower than the urge.
