Arkham Intelligence has offered a $150,000 bounty for whoever can identify the creator of the Solana-based token DJT — which rose up to 500% on Monday on unsubstantiated rumors it was tied to Donald Trump.

“Fuck it, we ball. $150,000 to the first person to definitively prove the identity of the creator of $DJT,” the firm posted to X on June 18.

The bounty will be live for eight days and paid in 100,000 Arkham (ARKM), worth $1.56 at the time of writing, according to CoinMarketCap.

“Find definitive evidence of the creator of $DJT. We will accept private proof for this bounty but if accepted that proof will be made public,” the bounty notice reads.

“The source must be original and not from elsewhere on the internet. You cannot claim this bounty by being the first person to link to the news broken elsewhere.”

High-profile blockchain sleuth ZachXBT is among those who have sent in a submission so far.

Bets are on: Did Trump launch DJT?

Elsewhere on the internet, people are placing bets on whether the DJT token was really launched by Trump or a member of his family.

Decentralized betting platform Polymarket shows there’s nearly $1.7 million in bets over whether the DJT token is “real.”

Only 17% of the total bets have been placed in the “Yes” camp, but for them to win, definitive proof must be obtained by 11:59 ET on June 21, or else the market will resolve to a “No.”

The rumor that Trump is behind the DJT token, “spearheaded” by his son, Barron Trump, first came from an X post by tech blog Pirate Wires, which cited “conversations” but didn’t elaborate on who those conversations were with.

Pressed on where the information was from, Pirate Wires creator Mike Solana noted he “didn’t speak with Trump directly” and was “just reporting what I know via sources.”

DJT is currently trading for 0.016, down 50% from its peak of 0.036 on Tuesday, according to Birdseye.
