Observation on prediction markets in the token world

Polymarket’s TokenSale market has processed nearly $250 million in transaction volume. The accuracy data advertised by the platform are impressive: the subscription amount prediction accuracy is 100%, and the FDV (fully diluted valuation) is over 90%. But upon closer analysis, these numbers are misleading. The real signal is not what the crowd predicted, but how wrong they were.

By analyzing 231 prediction markets across 29 token sales, and cross-referencing Polymarket’s historical probability data with actual token performance on CoinGecko, we found that “prediction markets are not reliable predictive tools. Instead, they are actually sentiment indicators and are often a contrarian signal.

Core finding: One week before the market close, the true forecast accuracy was only 66.7%. At critical moments, the public is wrong about one-third of the time, and erroneous forecasts often show systematic over-optimism.

24-hour volatility problem: Using CoinGecko’s hourly data, we found that Polymarket’s “FDV above X one day after publication” market is actually betting on extreme volatility. The average 24-hour rise and fall is ±23% (for example, the best performance: Monad +54.8%; the worst performance: Trove -38.7%). 75% of tokens sold off within 24 hours of opening. In this case, Polymarket's accuracy in 24-hour FDV prediction is only 62.5%.

The accuracy fallacy: the market is wrong one-third of the time

When the market probabilities we track change over time, rather than just looking at the static data at settlement, a completely different picture emerges. The reason why the subscription amount prediction market seems "100% accurate" is because as the sales progress, the final numbers will inevitably leak gradually. Informed people and observers update prices accordingly, which is simply price discovery after the fact.

Key Insight: The reason call and FDV markets tend to close with 100% accuracy is because they settle after the outcome has been largely determined. The subscription market closes after the sale; the FDV market closes 24 hours after release. The only meaningful predictor is accuracy 1 week before the close, which is when uncertainty really exists. The subscription forecast accuracy rate of 66.7% shows that at critical moments, the market is wrong 1/3 of the time.

Public predictions went wrong because they were too optimistic

We reviewed every prediction market where public confidence exceeded 60% but ultimately failed to materialize. In every case, the error was in the same direction: over-optimism. The public always believes that the financing amount will be higher than the actual value and the valuation will be more expensive than the reality.

This systematic bias suggests that participants in these markets are optimistic speculators who are attracted to token sales precisely because of their bullishness.

Over-optimism vs token performance (based on ICO data)

Methodology: This analysis only selects markets where public ICOs have been conducted and tokens have been issued, using Polymarket odds 1 week before market close.

Excessive optimism = (Polymarket forecast FDV - actual 24hFDV) / actual 24hFDV.

The Y-axis shows the price performance from the ICO to the current time.

The data shows that there is a moderate negative correlation between excessive optimism and ICO returns (r=-0.41). Monad is "undervalued/pessimistic" by the market (-25%), but its price is still down 24% from the ICO. Ranger is the most "over-optimistic" (+72%) and is currently down 32% from the ICO price. Only Football.fun remains above the ICO price (+1%).

Token performance ranking: 40% of the listed prices are lower than the valuation

The table below uses historical Polymarket odds 1 week before the close to reveal true prediction accuracy. The pattern is clear: extreme over-optimism portends disaster, and high trading volume on Polymarket is often a contrarian signal even when predictions are accurate.

Key findings: Among the tokens with ICO data, 40% of the tokens were listed at a price lower than their ICO valuation. The average return from ICO to current date is -32.2%. Only Football.fun is trading at a higher price than the ICO price.

This model is cruel: even tokens whose listing price is higher than the ICO valuation (such as Monad, Solomon) eventually fell below the issue price. Football.fun is the only winner among the 5 ICO tokens in this dataset and is currently only 1% above the ICO price.

Core conclusion:

After analyzing 231 markets, $241.5 million in trading volume, and 8 tokens with verified 24-hour FDV data, several conclusions are clear:

1. "100% accuracy" means nothing. The market is closed for settlement only after the result is known (the subscription market is after the sale, the FDV market is after 24 hours), so the accuracy rate in the later period is undoubtedly close to 100%. But the true forecast accuracy one week before the close was only 66.7%. At the critical moment, the public has a 1/3 probability of guessing wrong.

2. Systemic over-optimism. Five of the top 15 markets showed more than 60% confidence in a threshold that has never been touched. FDV is overvalued by +35% on average.

3. High trading volume in the forecast market is a contrarian signal. Monad ($89 million) and MegaETH ($67 million) have the highest levels of over-optimism. The more money the public bets, the more confident they become, and the more wrong they tend to be.

4. Conservative predictions = better results. Tokens with relatively accurate predictions (Monad, Football.fun) experienced smaller declines. Low hype and accurate forecasts appear to be bullish signs.

Trading signals:

Based on the analysis, we can distill actionable signals for evaluating future token sales. This is not an absolute guarantee, but represents a pattern that will always hold true in the data set.

Bearish Signal:

• Polymarket trading volume>50 million US dollars

• FDV over-optimism level>50%

• All FDV prediction thresholds are likely to fail

• Excessive optimism in subscription amount>30%

Bullish signal (relatively speaking)

• Polymarket trading volume <5 million US dollars

• FDV prediction deviation is within 20%

• Multiple FDV prediction thresholds were reached

• Public expectations are more conservative

This asymmetry is important. Bearish signals are strong indicators of bad outcomes. The bullish signal is weaker, merely suggesting that the token’s performance may look “less bad” than its over-hyped alternatives. In a market where all coins are falling from all-time highs (ATH), “a little less” is the best-case scenario.

Summary

Polymarket’s token sale section is actually a HypeMeter. The signal is not in the forecast itself, but in how far it deviated. When the public pours money into betting on higher valuations, it's wise to remain cautious. Historically, "extreme confidence" from the public often means "the greatest pain" for investors.
