Using Polymarket in Washington State on Your Desktop – Not an Option
While Polymarket is legal in California, Texas, New York, Washington, and most other states through the mobile app, its desktop version isn’t available in the US. American traders who want to make predictions through this site must download the app to their mobile device.
As an international brand that’s also regulated by the Commodity Futures Trading Commission (CFTC), Polymarket has created a dedicated app for its American users. This approach has made it possible for the prediction market to offer a tailored and legit service to US traders, including those based in WA.

Notable Events Related to Polymarket’s Legality in WA
I want to mention a few past and ongoing events related to this prediction market and make it clear how Polymarket is legal in Texas, Florida, Washington and most other states. Some of you may remember that the brand used to operate countrywide a few years ago, even though it wasn’t based in the US. It operated globally, and that approach got the brand in hot water with the CFTC, which fined and banned the prediction market site.
Polymarket’s response was to take over a Florida-based and CFTC-regulated company, which now handles its US operations. This step took place in 2025, and that’s also the year the prediction market resurrected its presence on the American market. That’s how Polymarket is legal in Washington State and any other state whose regulators haven’t taken specific steps to outlaw prediction market apps.
I mention “specific steps" because in some states, including Washington, there have been legal proceedings aimed against prediction market apps like Polymarket. For now, they don’t affect the app’s availability in WA, but things may change in the future. If that happens, I’ll update this page accordingly to keep you updated and informed.

I want to remind you that the app’s services and offers may vary by state. For example, Polymarket is legal in Florida, but what traders from Florida see may not always be the same as what you would see from Washington State. The best way to check what’s available to you is to open the app and see what appears on your phone.

Just like Polymarket is legal in New York, Florida, and Texas, the prediction market site is available in Washington State, too.

Things may change going forward as WA regulators are monitoring if prediction markets like Polymarket go against any state regulations. Until those proceedings resolve, Polymarket is allowed in Washington State and WA traders have no legal roadblocks to using the prediction site.
