How is market calibration calculated?

The sum of all player probabilities is currently ${totalPercent}%.

For a 26-man roster, the ideal sum would be exactly ${idealPercent26}%, since exactly 26 players will make the roster.

For a 23-man roster, the ideal sum would be exactly ${idealPercent23}%.

\n \n

What's currently happening with this market?

For a 26-man roster, users would need to knock a combined ${diffPercent26}% off of the current probabilities.

For a 23-man roster, users would need to knock a combined ${diffPercent23}% off of the current probabilities.

\n \n

How could this be fixed?

To calibrate the market for a 26-man roster, each player's probability would need to be multiplied by ${formatNumber(adjustFactor26)}.

To calibrate for a 23-man roster, each probability would need to be multiplied by ${formatNumber(adjustFactor23)}.

Curious about the final roster size? What will be the roster size for the 2026 FIFA World Cup?

\n `;\n \n let marketCalibrationText = '';\n if (totalPercent > idealPercent26) {\n marketCalibrationText = `\n

The market is overestimating player chances.

Users would need to reduce probabilities by a total of ${diffPercent26}% for a 26-man roster, or ${diffPercent23}% for a 23-man roster.

\n `;\n } else if (totalPercent < idealPercent23) {\n marketCalibrationText = `\n

The market is underestimating player chances.

Users would need to increase probabilities by a total of ${-diffPercent23}% for a 23-man roster.

\n `;\n } else {\n marketCalibrationText = `\n

The market is well calibrated for a roster size between 23 and 26 players.

Frequently Asked Questions

\n \n

What is this?

This is Charlie's attempt to make his USMNT World Cup Roster Prediction Market a thing.

\n \n

Well, is the USMNTWCRPM a thing?

As of writing this, not really. It has only received about $12USD in trades. And yet, it's still the most rigorous attempt that I know of to quantify who will be on this historic roster.

\n \n

Betting?? Isn't that a scam?

Honestly yes, especially with sportsbooks. However, this prediction market is hosted on Manifold Markets, which uses play internet money that you can't cash out. So it's more like gambling with Reddit karma. As of writing this, you can move the percentages significantly just by using the \"Mana\" you get by signing up. Moreover, while sportsbooks set unfavorable odds to take your money and restrict your account if you're actually good at predicting, prediction markets operate simply as a intermediate between users. There's no \"House\" conspiring against you.

\n \n

Seems sus.

That's fine! Prediction markets actually have two types of customers. 1: The degenerates who bet on them and 2. The casuals who get information from the results of the bets. You don't have to bet on events to get value out of them. Just sit back and watch Sebastian Berhalter overtake Pulisic as the brightest star in the USMNT Roster pool.

\n \n

Will the roster be 23 or 26 players?

FIFA expanded rosters to 26 players for the 2022 World Cup, up from the traditional 23. While no official announcement has been made for 2026 yet, you can see what the market thinks: What will be the roster size for the 2026 FIFA World Cup?

\n \n

Ok I'm warming up to the idea. Do you have other markets?

I'm glad you asked. I have a MLS Newcomer market here: [MLS Rumor Mill] What newcomers will make an appearance for a Major League Soccer team in 2025?

There's also Who will be the next Ballon d'Or winner to play in MLS?

\n \n

Tell me how you really feel.

I think most online communities would benefit if at least some percentage of their members were prediction market-pilled.

\n \n

Why?

Wild speculation is objectively entertaining, but at some point it would be nice if we could actually have a place where we could more formally evaluate who actually knows what they're talking about. Prediction markets solve this by forcing folks to put their (fake in this case) money where their mouth is.

\n \n

Why did you write this FAQ?

The average internet user is extremely and justifiable jaded about anything that sounds vaguely like gambling or crypto, myself included. This is a small attempt to humbly submit that there is a tiny corner of the internet where the whole \"gambling + weird fake money\" degeneracy thing can actually have positive externalities.
