Washington presents one of the most restrictive legal environments for online gambling and prediction markets in the United States. Its state statutes contain specific and severe classifications for internet-based wagering, creating a high-risk landscape for both operators and residents. This guide provides a detailed analysis of Washington's laws, regulatory posture, and the resulting access policies of major platforms.
Washington is classified as a Restricted state for prediction markets. The Revised Code of Washington Chapter 9.46 governs gambling, with sports betting limited to tribal casinos. Critically, RCW 9.46.240 makes transmitting or receiving gambling information via the internet a Class C felony. Consequently, major platforms like Kalshi have historically restricted access, and AGON geoblocks Washington. We recommend Washington residents do not trade on prediction markets.
At the federal level, the Commodity Exchange Act provides a framework for event contracts, regulated by the Commodity Futures Trading Commission (CFTC). Platforms registered with the CFTC as a Designated Contract Market (DCM) can offer certain event contracts legally under federal law. This federal oversight typically preempts state-level gambling laws for CFTC-approved products.
However, Washington's legal framework creates a significant conflict. The state passed HB 2638 in 2020, authorizing sports wagering exclusively at tribal casinos, with no provisions for commercial online or retail betting. More pointedly, RCW 9.46.240 explicitly classifies most forms of online gambling as a Class C felony. This uniquely hostile stance toward commercial online gambling creates substantial legal risk and uncertainty, causing most operators, including CFTC-regulated ones, to restrict access. The state’s aggressive posture overrides the potential for federal preemption in practice.

Washington’s statutes are explicit and severe regarding online gambling, forming the primary basis for its Restricted classification.
The state's approach is defined by the Revised Code of Washington Chapter 9.46 — Gambling. Several sections are critical to understanding the legal environment:
The Washington Office of the Attorney General has not issued a formal opinion specifically on whether CFTC-registered event contracts constitute "gambling information" under RCW 9.46.240.
Despite this, the Washington State Gambling Commission (WSGC) has a history of aggressive enforcement against unauthorized online gambling. It has actively pursued operators of illegal online casinos and took a firm stance that led daily fantasy sports operators to exit the state for years.
[INFERENCE]: The combination of the felony-level internet gambling statute and the WSGC's enforcement history creates a high-risk environment. While an argument for federal preemption for CFTC-registered DCMs exists, the potential for state-level criminal enforcement action against residents is a significant deterrent that informs operator decisions to geoblock the state.
The most significant recent legislative action was the 2020 passage of HB 2638, which legalized sports wagering only within the confines of tribal casinos. There have been no subsequent bills introduced to expand online betting to a commercial market or to specifically authorize CFTC-registered prediction markets.
A 2022 Washington Supreme Court decision in Maverick Gaming v. United States reaffirmed the tribal-exclusive gaming compact model. While not directly related to prediction markets, this case underscores the state's entrenched commitment to its current, highly limited sports wagering framework.
Given the legal risks, platform access for Washington residents is uniformly restricted.
Kalshi, a CFTC-regulated DCM, makes state-by-state availability decisions based on its own legal risk assessment. While users should always verify the latest information directly on kalshi.com, the platform has historically restricted access for Washington residents. This decision is likely a direct response to the legal ambiguity and potential for severe penalties under RCW 9.46.240. For more platform context, see our Kalshi review.
Polymarket, which operates outside the CFTC's regulatory framework, restricts access to all United States persons. This policy, detailed in its terms of service, was implemented following a 2022 settlement with the CFTC. Therefore, residents of Washington are prohibited from using the platform, consistent with all other US states.
AGON is a sport betting crypto platform on the Base blockchain, featuring an open AI Agent Arena and a gamification stack. Our availability is determined by federal frameworks and state-specific gambling statutes. Due to Washington's RCW 9.46.240 internet gambling felony classification and its restrictive tribal-only wagering model, Washington is on AGON's geoblock list. We do not solicit or serve users in Washington. Residents should not attempt to circumvent geoblocking, as doing so may violate AGON's terms of service and could expose the user to state-level legal risk.
Our recommendation is direct: Washington residents should not trade on prediction markets while residing in the state. The combination of the RCW 9.46.240 felony statute, the WSGC's enforcement history, and the consistent geoblocking by all major platforms creates an environment of unacceptable legal risk.
Before considering any action, Washington residents must weigh the Class C felony classification for internet gambling, the state's clear policy favoring a tribal-exclusive model, and the fact that operators block the state for commercial and legal reasons. User liability under state law remains regardless of platform access methods. Do not use VPNs or other tools to circumvent geoblocks. Always consult a Washington-licensed attorney before relying on any legal classification.

Washington's gambling framework — Revised Code of Washington Chapter 9.46, including RCW 9.46.240 (Internet Gambling Class C felony), the Washington State Gambling Commission's enforcement posture, and the 2020 tribal-only sports wagering law — is among the most restrictive in the United States for commercial online gambling. AGON does not provide legal advice. AGON geoblocks Washington residents. We recommend Washington residents do NOT trade prediction markets while Washington-resident. Consult a Washington-licensed attorney before any reliance on any classification.

Kalshi has historically restricted access for Washington residents. As a CFTC-regulated Designated Contract Market, Kalshi makes its own risk assessments for each state. The primary reason for restricting Washington is likely the state's Revised Code of Washington 9.46.240, which classifies transmitting or receiving gambling information online as a Class C felony. This creates significant legal risk and ambiguity. You should always verify Washington's current status directly on kalshi.com, but access has not been permitted in the past.
No. Polymarket's terms of service restrict all users from the United States following a 2022 settlement with the CFTC. This is a platform-wide policy that applies to residents of all 50 states, including Washington. Separately, Washington's own state law (RCW 9.46.240) makes most forms of online gambling a felony, creating an independent and severe legal barrier for residents seeking to use such platforms.
Washington's stance is classified as Restricted and is considered hostile to commercial event contracts. The state's legal framework does not distinguish between sports betting, online casinos, or event contracts, grouping them all under a broad definition of gambling. The combination of RCW 9.46.240 (the internet gambling felony law), a sports betting market limited exclusively to tribal casinos, and an aggressive enforcement history from the Washington State Gambling Commission results in a high-risk environment where major operators do not offer services.
No. AGON geoblocks Washington residents and does not solicit users from states with a Restricted status. This decision is based on the severe legal risks posed by Washington's laws, specifically RCW 9.46.240, which makes online gambling a felony. We strongly advise Washington residents not to attempt to circumvent these geoblocks. Doing so may violate our terms of service and, more importantly, could expose the user to criminal liability under state law.
Washington is considered hostile primarily because of one statute: RCW 9.46.240. This law classifies the act of knowingly transmitting or receiving gambling information over the internet as a Class C felony, which is among the most severe anti-internet-gambling laws in the United States. This is reinforced by the state's 2020 sports betting law (HB 2638), which exclusively authorized wagering at tribal casinos, deliberately excluding a commercial online market. The Washington State Gambling Commission's history of strict enforcement further cements the state's hostile posture.
