Which updates may fly under radar?

Ecuador

On February 11, 2026, Ecuador published legislation updating their existing gaming framework to specifically regulate sports betting.

Under the legislation, contained within Title 3, Chapter 3 of the Organic Law of Sport, Physical Education and Recreation and which repeals the 2010 Sports Law, Ecuador's gaming framework is reformed as follows and addresses:

• Transition from an indirect regime, through taxation, to specific regulations aimed towards sports betting.
• Obligation to operate specifically on online platforms under supervision by the public.
• New integrity, transparency, and traceability requirements.
• Responsible gaming policy requirements for operators.
• Restrictions and prohibitions for sports betting operators.
• Reform impact on operators, suppliers, and financial stakeholders. 

This follows a December 2024 decree amending Ecuador's taxation regime, along with introducing a licensing framework for sports betting. Regulations that expand upon the sports betting regime are expected 120 days upon the publication of this law in the Ecuador National Gazette, i.e., June 11, 2026.

Washington

On March 30, 2026, Washington Governor Jay Inslee signed Senate Bill 6137 into law to prohibit betting on individual performances of Washington-based college athletes, among other restrictions.

Specifically, the legislation states that sports wagering may not be conducted on:

• The performance or nonperformance of any specifically named individual participant in any collegiate sport or athletic event who is enrolled in an educational institution located within the state of Washington.
• An in-game decision made by a coach who is employed by an educational institution located within the state of Washington.
• An officiating decision in a collegiate sport or athletic event offered or sponsored by, or played in connection with, an educational institution that is located within the state of Washington.

"In-game decision" means a player substitution, a call for a timeout, a request or challenge for replay review, or an appeal of an officiating decision.

"Officiating decision" includes, but is not limited to, an officiating assignment, a call or ruling for a penalty, foul, violation, or replay, or any other decision by a sports official, referee, or umpire that involves the individual's judgment.

The law also aims to protect student-athletes from harassment, including physical damage or threatening conduct. Violators of the legislation may be found guilty of a gross misdemeanor, subject to penalties under RCW 9A.20.021. SB6137 takes effect June 11, 2026.
