The only official Polymarket app is the Polymarket US app for US residents: it is on Apple's App Store (seller Blockratize Inc, app ID 6648798962) and listed on Google Play as com.polymarket.android, although Polymarket's Help Center still calls the Android version “coming soon”. The international site polymarket.com has no app of its own and runs in any modern mobile browser.
This guide explains which Polymarket apps are genuine, how to install the official one from Apple's or Google's store and what happens on first launch, and how to check an app or APK file before you give it any login details. Every fact comes from Polymarket's help center and docs, the official store listings, dated news reports and other third-party sources, and where Polymarket's own sources disagree we say so. PolyKal has no app of its own, and this page is not an invitation to install an app or open an account.
US residents can't deposit or trade on polymarket.com; they use the separate Polymarket US app. Polymarket also blocks or limits trading in many other countries, and governments add blocks of their own. Check where Polymarket and Kalshi are available before you move any money.
Polymarket's Terms of Use prohibit using a VPN or similar tool to get around these restrictions, and doing so can also break local law. PolyKal doesn't help anyone get around them.
Polymarket runs two separate products, and only one of them is an app:
Polymarket's Help Center says the two accounts are not connected: a polymarket.com account doesn't work in the US app, and the reverse. The main differences:
| At a glance | polymarket.com | Polymarket US app |
|---|---|---|
| How you use it | Any modern browser on a computer, tablet or phone; no app | iPhone app from the App Store; Android listing on Google Play |
| Who it's for | Users outside the US, where Polymarket isn't restricted | US residents |
| Sign-in | Google, email with a 6-digit code, or a crypto wallet | Google or Apple ID only |
| Identity check | No ID step in the sign-up flow | Name, date of birth and address; sometimes a photo ID and a selfie |
| Money | Crypto, held as pUSD on Polygon | US dollars by debit card, bank transfer or wire |
| Minimum age | 18 (Terms of Use) | 18+ on both store listings |
| Support | [email protected] or the chat on the site | [email protected] or in-app chat |
Polymarket's Help Center describes polymarket.com as a website that is “accessible on any device with a modern browser - desktop, tablet, or mobile”, and the only app it lists is the US product. There is no separate Polymarket app for international users.
When we checked on September 24, 2026, the App Store listing opened in the US store but not in the Canadian or German stores, which suggests it is offered in the US store only. If you're outside the US and can't find the app, that is expected, not a fault.
To use polymarket.com on a phone:
If the site shows a network error on your phone, Polymarket's Help Center suggests turning off VPNs, proxies and privacy extensions, checking that your device clock is correct, clearing the site's data, refreshing the page, and signing out and back in.
Older articles that say Polymarket has no app, or that describe an election-forecast app, are out of date. According to the developer's own case study and other reports, the same App Store ID first appeared around September–October 2024 as a read-only election news and forecast app with no trading, before it became the US trading app.
Polymarket's own sources disagree about Android, and we can't tell you which one is current:
Blockratize Inc. is the company behind Polymarket: it is the seller of the iPhone app and is named as Polymarket's operator in US court filings and a Department of Justice release. Either the Help Center page hasn't caught up with the Play listing or the Android rollout is staged; Polymarket hasn't said which, and we found no official announcement of an Android launch date.
News reports from May 12, 2026, when Polymarket opened the iPhone app to all US users, said there was still no Android app at that point. Reports since then disagree on whether Android access is fully open or still goes through a waitlist.
In practice, the only Android listing with a clear link to Polymarket's company is com.polymarket.android on Google Play. Install that one or none, and don't replace it with an APK file from another site.
Play Store searches also show a listing called Polymarket [Internal] (package com.polymarket.android.debug). We found no explanation of it from Polymarket and it isn't the listing described above, so don't install it.
These steps are for US residents. Store titles change with seasonal marketing (we've seen “Polymarket: Trade Live Sports” and “Polymarket: Trade Soccer”), so identify the app by its developer, seller and ID rather than its name.
The Polymarket US docs describe five sign-up steps and don't distinguish between iPhone and Android. Labels on screen may differ slightly.
People often ask whether the app needs a Social Security number. The retail sign-up page doesn't mention one, but Polymarket US's documentation for partner apps lists it among the identity data. Whether the app itself asks for it, and if so for the full number or only the last four digits, isn't confirmed.
The App Store listing says “18+ only. Restrictions and eligibility requirements apply” and that trading is currently unavailable in Nevada. News reports name more states where new accounts are restricted, but we found no official list, so check the app itself and our availability page.
For sign-up on both products, including polymarket.com, see how to sign up for Polymarket.
An APK is an Android app file installed from outside the Play Store. Several third-party mirror sites republish Polymarket's Android files, some with versions going back to November 2024, when the package was an election-forecast app. We found no official Polymarket statement about APK files or installing from outside Google Play, and no Polymarket page offering an APK download.
That makes an APK from another site a risk for three reasons:
We found no reported case of a fake Polymarket APK being used to steal money, but that is not evidence that files from other sites are safe. If the Play Store listing isn't available to you, don't look for the file elsewhere.
Run through these checks before you sign in to any app that uses the Polymarket name:
Store searches also return apps from other developers, such as Polymtrade: Polymarket Trading (seller Accunex Digital Ltd), Polymarket Alerts and Ares: Polymarket Smart Trading. None of them is published by Polymarket's company. One claims in a review reply to be an official Polymarket partner; Polymarket doesn't list it and we couldn't confirm the claim. Not being official doesn't make an app a scam, but these apps aren't Polymarket, so never give them your Polymarket login codes or private key.
These incidents were reported by news outlets and security researchers; amounts and details are as reported. Polymarket's Help Center has no dedicated page on phishing: a search for the word returned no articles on September 24, 2026.
We found no reported case of money stolen through a fake Polymarket app or APK. The reported losses came through links in comments, social posts and emails, a third-party login provider, third-party code on the real website, and a registration flaw in the US app. That's why the checks above cover links and login requests, not just app listings.
If you've entered a login code, private key or password into an app or page you now doubt, contact Polymarket support through the official channels above straight away, and secure the Google, Apple or email account you sign in with, for example by turning on its two-step verification. Polymarket says its support can't recover funds lost through a shared login code.
Kalshi is a separate prediction market run by a different company, with its own official apps. Both store listings name the developer KalshiEX LLC:
As with Polymarket, check the developer name rather than the title. Play Store searches also show apps such as Trading Tool: Kalshi (package com.trading.klshi) and apps from a developer called Major Kalshi Classes Pvt Ltd; none of them is from Kalshi. Whether you can open a Kalshi account depends on where you live: see where Polymarket and Kalshi are available, and how Kalshi works for the basics.
Yes, one: the Polymarket US app for US residents, on the App Store (developer Polymarket, seller Blockratize Inc, ID 6648798962) and listed on Google Play as com.polymarket.android. The international site polymarket.com has no app and works in any modern mobile browser.
Only from Apple's App Store or Google Play: search the store yourself and check that the developer is Polymarket and the seller or company is Blockratize Inc. It is the US product; the listing didn't open in the Canadian or German App Store when we checked. Outside the US, Polymarket is used through polymarket.com in a browser, in places where it's available.
Polymarket's sources disagree. Its Help Center (updated June 25, 2026) says the Android app is “coming soon on the Google Play Store”, while Google Play showed an installable listing, com.polymarket.android from Polymarket / BLOCKRATIZE INC., with more than 1 million downloads on September 24, 2026. On Android, use only that Play listing.
Polymarket offers no APK download anywhere we could find and has published nothing about installing its app from outside Google Play. APK files on other sites can't be checked the way a store listing can, and some are old builds of the 2024 election-forecast app. Use Google Play or nothing.
No. Polymarket's Help Center describes polymarket.com as a website for international users that works on any device with a modern browser, and the only app it lists is the US product. Apps from other developers that use the Polymarket name aren't Polymarket's. Polymarket also blocks or limits many countries, so check availability first.
No. Polymarket's Help Center says US app and website accounts are not connected. The US app needs its own sign-up with Google or Apple ID and its own identity verification.
Check the developer and seller (Polymarket and Blockratize Inc), the App Store ID 6648798962 or the package com.polymarket.android, and that you found the app by searching the store yourself. Polymarket says it will never ask for your private key; an app or page that asks for it, or for your login or verification codes, isn't Polymarket.
Yes. The US app asks for your full name, date of birth and residential address. Most users are verified automatically; others may be asked to upload a government-issued ID and take a selfie, and a manual review can take up to 3–5 business days. The polymarket.com sign-up flow has no ID step.
Several have been reported, including a comment-section link to a lookalike sign-up page in January 2026, a fake token airdrop and a fake invitation email in June 2026, and a malicious third-party script on Polymarket's own website in late June 2026. We found no reported theft through a fake Polymarket app.
Yes. Kalshi's apps are on the App Store (ID 1632713844) and Google Play (package com.kalshi.mobile), both from the developer KalshiEX LLC. Kalshi is a separate company from Polymarket, and whether you can use it depends on where you live.
No. PolyKal is a free, read-only research website with no app, no accounts and no trading. Any app that claims to be PolyKal isn't ours.
Every fact on this page comes from the sources below, checked on September 24, 2026. Store listings change their titles, versions and download counts often, and Polymarket's app plans can change; we re-verify this page quarterly.
