This Sunday, the League of Legends S15 World Championship Finals will feature T1 vs. KT. As a long-time fan, I believe this will be an absolutely spectacular match. Will BDD forever etch his name in S15, replicating Deft's "ten-year dream chase"? Or will Faker claim his "sixth world championship," a title bestowed upon Doran?
With the finals just around the corner, Odaily Planet Daily has compiled a list of three of the most discussed Web3 prediction market platforms to guide you step-by-step on how to participate in betting on this competition, allowing you to watch the games while potentially winning airdrop token rewards.
Polymarket (No token yet)
Introduction

Polymarket is a prediction market platform within the Polygon ecosystem, gaining widespread recognition for its accurate prediction of Trump's victory in the 2024 US presidential election. Its predictions in several key swing states closely mirrored reality, quickly establishing it as a leading player in the industry and one of the most influential decentralized prediction market platforms today.
On October 7, The Wall Street Journal reported that Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, is close to investing $2 billion in Polymarket, a decentralized prediction market platform. This could not only be one of the largest private funding rounds in the history of the crypto space, but also mark a deep convergence between traditional financial infrastructure and the Web 3 market model ( for more related content, see: Why is the NYSE betting $2 billion on Polymarket? ).
In addition, at the end of October, Polymarket announced that it would reopen to US users by the end of November (the company had been forced to relocate from the US due to CFTC penalties), and planned to launch the POLY token and airdrop after the US operations resumed ( for more speculation about the token issuance, see: Polymarket may issue a token, filing documents reveal clues ).
