Anthony Joshua to walk out against Jake Paul with a $400K Polymarket diamond necklace

• Jake Paul and Anthony Joshua are supposedly set to split a $267-million prize pool
• AJ has received a $400,000 diamond necklace with the Polymarket logo ahead of the fight
• More than 50m people are expected to tune in and watch the fight

The upcoming bout between Anthony Joshua and Jake Paul tonight, Friday, December 19, 2025, has so much going on. The event is expected to pull in more than 50m viewers and, although a far cry from the 100m+ pulled during Jake Paul vs Mike Tyson’s fight, it’s still a chonker by any reasonable streaming standard.

Broadcast by Netflix, things just got more interesting with a prediction market platform pulling off a clever marketing stratagem to insert its name in front of millions of eyeballs. Polymarket, a global leader in event contracts, has sent Anthony Joshua a $400,000 diamond necklace.

The English boxer shared the news, recording himself opening the gift box and pulling out the diamond-laden and shiny necklace, which he intends to wear during his pre-fight walkout against Jake Paul.

It’s an almost anecdotal situation, given that one of Jake Paul’s companies is an early investor in Polymarket and participated in a Series A funding round back in 2021.

In the meantime, the stakes have risen, with AJ supposedly saying that he would "kill" his opponent if he could, engaging in the language that Deontay Wilder, a fellow heavyweight talent, has been heavily criticized for.

Polymarket’s clever marketing strategy is definitely fun, and it raises the question of whether Anthony Joshua is an ambassador for the prediction market platform. There is no official confirmation that he is, but this sort of video messaging timed with the fight most certainly suggests a backchannel of communication.

In the meantime, the prize purse for the fight supposedly grew to about $270m, making it one of the most worthwhile bouts of all time, with the fighters set to split the chunk of it.
