2026 FIFA World Cup Generated $20 Billion In On-Chain Betting As Chainalysis Tracked Millions In Illicit Crypto Funds

World Cup Betting Boom Sends $20 Billion Through Blockchain Markets as Illicit Funds Also Surface

The 2026 FIFA World Cup became more than just football's biggest tournament.

It also turned into the largest event ever for blockchain prediction markets, with billions of dollars flowing through decentralised betting platforms as fans wagered on everything from match results to emotional moments on the pitch.

A new report from blockchain analytics firm Chainalysis found that around $20 billion in prediction market volume was linked to the tournament.

While most activity came from legitimate users, investigators also traced millions of dollars in transactions back to sanctioned exchanges and other illicit sources, showing how rapidly growing blockchain markets are also attracting unwanted financial activity.

World Cup Betting Reached Record Levels

Chainalysis said more than 400,000 wallets participated in on-chain betting throughout the tournament.

Prediction markets were already seeing around $50 million in daily trading during the qualifying period in early 2026.

Activity accelerated sharply after the tournament kicked off on 11 June, with daily volume climbing above $250 million before peaking at more than $300 million on the day Spain defeated Argentina 1-0 in the final.

Although the overall total reached $20 billion from January onwards, roughly $5.7 billion was traded during the five-week tournament itself.

During that period, FIFA World Cup markets accounted for about 63% of all prediction market activity.

The report said,

"During the tournaments, FIFA World Cup markets made up approximately 63% of total prediction market volume."

Beyond match outcomes, bettors also flocked to novelty markets.

One of the most popular asked whether Cristiano Ronaldo would cry at the end of what was expected to be his final international campaign.

The correct "yes" outcome generated $49 million in trading volume.

Which Countries Drove The Most Betting Activity

The United States and China generated the highest attributed betting volumes, according to Chainalysis' geographic analysis.

Canada, Thailand and the United Kingdom followed closely behind, while Australia, Brazil, Russia and India also recorded significant participation.

The firm noted that wallet locations are estimated using its proprietary attribution methods and may not always represent a user's verified residence because privacy tools such as VPNs and mixers can obscure activity.

Most participants also appeared to be experienced traders.

Around 80% of profitable bettors had previously used prediction markets, while 55% of all participants finished the tournament in profit.

One high-profile loss came from an on-chain trader identified as gud.hl, who reportedly staked $5.2 million on Argentina to win the World Cup, mainly through Polymarket.

Spain's victory erased most of the trader's accumulated profits on Hyperliquid.

Millions In Sanctioned And Scam-Linked Funds Entered Betting Markets

Despite the huge scale of legitimate activity, Chainalysis identified approximately 3,700 wallets with previous links to illicit transactions, representing less than 1% of all participating wallets.

The firm traced around $5.4 million in funds entering World Cup betting wallets from the sanctioned cryptocurrency exchange Huobi, now operating under the HTX brand.

Additional suspicious activity included roughly $2 million from scam-linked wallets and more than $800,000 connected to stolen funds.

Although these amounts represent only a small share of the overall $20 billion traded, Chainalysis said they remain significant for organisations responsible for monitoring financial crime and sanctions compliance.

The report noted that historical wallet activity does not necessarily mean every flagged participant committed offences through their World Cup betting.

TRM Labs also identified active scam wallets connected to fake ticket sales and fraudulent match betting schemes during the tournament, while the FBI issued warnings about more than 30 fake FIFA-related websites targeting football fans.

FIFA Collect Took A Different Approach

While prediction markets attracted illicit fund flows, FIFA's own blockchain platform presented a very different picture.

Built on the Avalanche blockchain, FIFA Collect allows supporters to buy and trade official digital collectibles while also providing access to selected match tickets through its Right-to-Ticket products.

More than 100,000 match tickets were processed through the platform as fans either redeemed or resold digital assets for stadium entry.

Chainalysis tracked approximately $24 million in stablecoin transactions flowing into a key FIFA Collect smart contract from May 2025 through the end of the tournament.

Based on the platform's 5% share of secondary sales, FIFA earned at least $6 million in transaction fees.

Unlike open prediction markets, FIFA Collect requires identity verification.

Chainalysis found that less than 0.01% of users held wallets associated with sanctioned entities.

The firm said the platform's strict Know Your Customer (KYC) requirements may explain its minimal exposure to illicit funds.
