Polymarket actually runs as two separate products: the original Polymarket.com, used outside the US, and Polymarket US, a CFTC-regulated exchange launched for US traders. Which one you're on determines which support channel reaches an actual human, and neither one answers a phone. Yes, that’s right; there is no Polymarket phone number on either version of the platform.
That split matters because the two sites don't share a support desk. Polymarket US, running as a designated contract market, routes requests by category instead of through one general inbox.
The Three Contact Paths on Polymarket US
If your issue is with the software itself rather than a trade or settlement, you're filing it as a technical support ticket, not a trading inquiry, and mixing the two just slows the response down.
The third row is easy to miss. An ISV is a separate company whose trading application connects to Polymarket US's exchange. If your issue is with that app specifically, Polymarket US's own contact page directs you to the ISV provider directly, since Polymarket doesn't control that software.
We track wallet activity and market data across Polymarket and Kalshi in one place, and one pattern we see often in support-related questions is users assuming a single "Polymarket support" handles both the international site and Polymarket US. It doesn't. A Reddit user who bet on the Knicks final ran into exactly this kind of confusion after clicking "cash out" and not knowing where the money had gone - the kind of settlement question that belongs in the clearing row above, not a general help inbox. If you're trying to figure out whether your market is even accessible in the first place, Polymarket's supported and restricted countries explain which version of the site you'd be dealing with before support enters the picture at all.
Scam Warning: Neither Venue Has A Phone Line
The absence of a phone number is not an oversight. Neither Polymarket.com nor Polymarket US publishes one, and neither runs support through Discord, Telegram, or a direct message. That absence is itself the security check: if a phone number or a DM ever claims to be Polymarket support, it isn't.
Three Signs a "Support" Message Is Fake
Oddsshopper's reporting states this plainly, and the tells sit together for a reason:
That third tell, the lookalike domain, is the one that catches people off guard, because Polymarket's own split into .com and .us already trains users to expect more than one legitimate-looking URL. A scam site copying either layout exploits exactly that expectation. The safest habit is the same one that applies to any exchange: type the domain in yourself rather than clicking a link from an unsolicited message, and treat any request to send funds elsewhere "to verify" as an immediate stop.
Not every confusing moment on Polymarket is a scam, though. Markets settle on outcomes that can be genuinely contentious even when nothing has gone wrong technically. The Epstein files market, for example, saw odds climb past 95 percent as pressure built for a resolution, and a market moving that fast toward settlement is the kind of moment where a user might mistake normal volatility for a broken platform. It's a useful contrast to keep in mind before assuming any unexpected market behavior means you need to reach support at all.
What Support Cannot Fix, Because Nothing Is Broken
Polymarket US's support queues exist for things that are actually broken: a login that won't authenticate, an interface bug, a clearing discrepancy. They don't exist to relitigate a market's outcome once it has resolved according to its own rules. If a contract settles in a way you didn't expect, that's a dispute over the resolution criteria, not a technical fault, and it isn't fixed the same way a bug is.
Broken vs. Contested: Two Different Problems
Some markets make that distinction obvious after the fact. A market on California's 5% billionaire wealth tax vote resolves on a specific, verifiable outcome once the vote happens. There's no ambiguity in the resolution for support to adjudicate. Compare that to a lighter case: the site tracks plenty of markets built purely for entertainment, where the stakes are low enough that a contested resolution is a curiosity, not a support ticket. The underlying mechanism is the same either way. Support fixes the plumbing. It does not referee the outcome.
Where the line does blur is settlement timing and where funds land after a cash-out, which is exactly the DCO and clearing category from the table above. If your funds haven't shown up after a market closes, that's a clearing inquiry, not a technical one, and routing it correctly the first time is the difference between a same-day answer and a ticket that sits in the wrong queue.
The Number You Were Looking For Doesn't Exist, But The Right Channel Does
You came here looking for a Polymarket phone number, and the honest answer is that filing your issue under the right category, on the right version of the site, gets you further than a phone call would anyway. Know which Polymarket you're on, know whether your issue is technical, trading, or clearing, and never trust a channel that reached out to you first.
If you're exploring the broader prediction market and crypto space beyond trading itself, how phone-based crypto mining works through Acurast is a different use for your phone than the one you came here hoping for, but worth a look if that side of the ecosystem interests you.
Frequently Asked Questions
Does Polymarket have a customer service phone number?
No. Neither Polymarket.com nor Polymarket US publishes a phone number. Support runs through their contact pages, split by category, and neither company offers phone-based support.
What is the Polymarket support email?
Polymarket US routes support by issue type through its contact page rather than one general email, splitting trading and technical issues from clearing and settlement inquiries. Which address applies depends on which category your issue falls into and which version of Polymarket you're using.
How do I know if a Polymarket support message is a scam?
Any message that reaches out to you first, asks you to move funds to "verify" your account, or links to a domain you didn't type yourself is not Polymarket. Legitimate support never initiates contact through Discord, Telegram, or direct message.
Can Polymarket support reverse a market's outcome?
No. Support resolves technical issues like login problems, interface bugs, and clearing discrepancies. It doesn't relitigate how a market resolved once the outcome is determined by that market's own resolution criteria
