High Roller Technologies (ROLR), which operates online casino platforms, signed a nonbinding letter of intent with Lines.com for a marketing partnership to support its planned entry into US prediction markets.

High Roller said Thursday that the partnership with Lines.com, a sports media platform owned by Spike Up Media, is designed to introduce its offerings to an audience familiar with implied probability, odds-based decision-making, and event-driven trading dynamics.

High Roller shares jumped 33% in Thursday trading. On Wednesday, the stock surged more than fivefold after the company entered into a binding letter of intent for an exclusive partnership with Crypto.com Derivatives North America to launch an event-based prediction-markets product in the US.

In a separate statement Thursday, High Roller said it is collaborating with Power Protocol to explore Web3-enabled engagement models.

High Roller said that the companies will evaluate how Power Protocol's incentive-based user experiences may be used to boost engagement across its casino brands.
