Mantle Network is a modular Ethereum Layer 2 that separates execution, consensus, and data availability into distinct layers to keep transaction costs low while remaining fully compatible with Ethereum tools. Right now, Mantle and the prediction platform InsightX are running a joint promotion tied to the 2026 FIFA World Cup knockout stage and are among several sports organizations that have moved into crypto prediction markets recently.
Status: Active
Entry Deadline: July 20, 2026
Spotlight Teams: Spain, France, Argentina, England
Eligibility: MNT or supported stablecoin wallet, plus an X account to follow official pages and post a quote tweet
Ten winners will split a $2,000 prize pool for correctly predicting knockout match outcomes on InsightX and explaining their reasoning in a public post, a cash-prize structure rather than a fixed MNT token allocation.
Eligibility for the InsightX World Cup Contest
Anyone with a wallet holding MNT or a supported stablecoin can enter, since InsightX runs natively on Mantle and requires funds on the network to place a prediction. There are no geographic restrictions or minimum holding sizes listed in the official rules shared so far. Every correct knockout call, paired with a written explanation of the reasoning behind it, counts as one entry toward the $2,000 pool.
The current spotlight round covers four teams: Spain, France, Argentina, and England. Mantle and InsightX have said that getting the outcome right qualifies an entry, but the quality of the reasoning behind the pick determines who actually wins, so a one-word guess and a well-reasoned call are not treated the same way. The same predictions double as entries in a separate leaderboard contest, the Mantle Prediction Cup, so one submission counts toward both campaigns at once.
How to Claim Your Entry into the $2,000 Pool
- Follow the official accounts. Follow @Mantle_Official and @InsightXHQ on X. Both accounts post the official rules and confirm winners once the challenge closes, so this is where to check for updates or rule changes.
- Fund a wallet on Mantle. Fund a wallet with MNT or a supported stablecoin, since placing a prediction on InsightX requires holding assets on Mantle. If you do not already hold MNT, you can purchase it on Bitget and bridge it over using Rhino Bridge.
- Place your prediction. Go to InsightX and place a prediction on the current or upcoming World Cup knockout match. The platform shows AI-generated market signals before you commit, worth a look before locking in a pick.
- Quote-tweet your pick. Take a screenshot of the prediction and quote-tweet the official challenge announcement with the screenshot and a short written explanation for the call. Tag @Mantle_Official and @InsightXHQ in the post.
- Confirm your entry. Drop the link to the quote tweet in the replies under the official announcement. This is what confirms the entry. A prediction without a submitted post link does not count, no matter how correct it turns out to be.
Risks to Consider
A few factors are worth weighing before bridging funds or submitting a prediction.
1. Bridge Security
Bridging funds to a new network always carries some risk, so double-check the Rhino Bridge contract address against the link Mantle itself shares before sending anything.
2. Subjective Prize Judging
Prize distribution here is not purely mechanical. Mantle and InsightX have said reasoning quality plays into who wins among correct entries, and that judgment call has not been detailed publicly, which leaves some room for subjective scoring.
3. Platform Dependency
The entry process also depends on a third-party platform, X, staying up and the quote tweet actually posting and linking correctly.
4. Mid-Tournament Rule Changes
If either account changes the rules mid-tournament, as the source material’s mixed signals on the deadline suggest could happen, entries already submitted may need to be resubmitted or reconfirmed.

Frequently Asked Questions
Need a quick refresher before entering? Here are the questions that most often come up for readers new to this challenge.
Do I need to hold MNT to enter?
Yes, InsightX runs on Mantle Network, so placing a prediction requires a wallet funded with MNT or a supported stablecoin on that network.
What happens if my prediction is correct but my reasoning is weak?
A correct call qualifies as an entry, but Mantle and InsightX have said reasoning quality factors into who wins among the pool of correct predictions, so a stronger explanation may carry more weight than the outcome alone.
Can one entry count for more than one contest?
Yes. The same prediction submitted for this challenge also counts toward the separate Mantle Prediction Cup leaderboard, so a single entry does double duty across both campaigns.
What if I miss the quote-tweet step?
The entry will not count. Placing a correct prediction on InsightX is not enough on its own; the quote tweet with a screenshot and reasoning, plus the reply link under the official announcement, is what confirms participation.
