- Vitalik Buterin said prediction markets force accountability that social media lacks.
- He argued that betting markets reward accuracy while punishing exaggerated or false claims.
- Buterin rejected markets that incentivize harm, such as assassination-related predictions.
Ethereum co-founder Vitalik Buterin claims that prediction markets offer something social media does not, i.e., accountability.
In a recent discussion on Farcaster, Buterin argued that betting markets such as Polymarket act as an “antidote” against exaggerated claims, emotional reactions, and misinformation that spread freely across social platforms.
Buterin’s argument is simple. On social media, users can make bold claims about wars, disasters, or political outcomes with no cost if they are wrong. Those claims often gain attention, followers, and money through engagement. When the prediction fails, there are no consequences.
Prediction markets work differently. Participants must put money behind their views. If their prediction is wrong, they lose. Over time, this system rewards accuracy and penalizes exaggeration.
Buterin said this makes prediction markets more focused on truth than platforms driven by likes and headlines.
He pointed to personal examples of reading alarming news stories, then checking Polymarket prices. In several cases, market odds showed only a 4% chance of the feared outcome, which helped him better judge the real risk instead of reacting emotionally.
The Ethics of Betting on Tragedy
The debate began after criticism that betting on events like wars or deaths represents a moral failure within crypto. A Farcaster user questioned whether markets predicting deaths cross an ethical line.
Buterin drew a clear distinction. He said markets that could directly incentivize harm, such as assassination markets, should not exist and should be opposed.
He added that systems already have ways to break or invalidate unethical markets, giving examples of past designs that allowed communities to reject certain outcomes.
At the same time, Buterin argued that small-scale markets focused on large public events do not meaningfully increase the risk of harm.
The Ethereum co-founder added that similar incentive problems already exist in traditional financial markets, where large actors could theoretically profit from disasters by shorting stocks.
Why Prediction Markets Are Harder to Manipulate
Buterin also explained why he sees prediction markets as healthier than many trading environments. Prices in these markets are limited between zero and one, a 0% to 100% probability.
This structure reduces extreme speculation and limits pump-and-dump behavior seen in crypto and stock markets.
Because prices cannot spiral endlessly higher, prediction markets are less affected by hype cycles, volatility, and the idea that someone else will always pay more later.
Meanwhile, the popularity of prediction markets continues to increase. A recent report showed that activity on major platforms has surged from under $100 million per month in early 2024 to more than $13 billion. Analysts expect this growth to continue through the decade.
