Vitalik Buterin Calls Prediction Markets’ Current Path “Corposlop”

Key Highlights

Vitalik Buterin warned that prediction markets are over-optimizing for short-term speculation, calling the trend “corposlop” driven by bear-market incentives.
He argued that current platforms rely too heavily on uninformed traders, creating incentives to promote low-quality beliefs instead of useful information.
Buterin proposed a future where prediction markets act as personalized hedging tools, potentially replacing stablecoins with expense-based prediction baskets.

Ethereum co-founder Vitalik Buterin has raised concerns about the current direction of prediction markets, arguing that while the sector has achieved scale and relevance, it is increasingly converging on short-term, dopamine-driven use cases that offer little long-term societal value.

In a detailed post, Buterin said prediction markets today are largely dominated by cryptocurrency price bets, sports betting, and similar speculative products. These markets generate high volume and revenue, particularly during bear markets, but risk locking platforms into what he described as an unhealthy product-market fit.

“Recently I have been starting to worry about the state of prediction markets, in their current form,” Buterin wrote. “They have achieved a certain level of success… but also, they seem to be over-converging to an unhealthy product market fit.”

Buterin acknowledged that prediction markets can be useful as a supplement to traditional media and that market depth is now sufficient for full-time professional traders. However, he argued that platforms are increasingly incentivized to cater to speculative behavior rather than meaningful information discovery.

“My guess is that teams feel motivated to capitulate to these things because they bring in large revenue during a bear market where people are desperate,” he said, adding that this dynamic ultimately “leads to corposlop.”

While he noted that there is nothing inherently immoral about profiting from traders with incorrect opinions, he warned that relying too heavily on such participants creates perverse incentives for platforms to encourage low-quality beliefs and engagement.

Who Loses Money in Prediction Markets?

Buterin broke down prediction markets into two essential groups: informed traders who provide valuable information and earn money, and participants who lose money.

He identified three types of actors willing to consistently take the losing side:

Naive traders who hold incorrect beliefs

Information buyers who subsidize markets to extract insights

Hedgers who accept negative expected value in exchange for reduced risk

According to Buterin, today’s markets overwhelmingly rely on the first group.

“This gives the platform the incentive to seek out traders with dumb opinions, and create a public brand and community that encourages dumb opinions to get more people to come in,” he wrote.

Why Information Buying Falls Short

The second model, information buyers, has long been championed by prediction market theorists like Robin Hanson. Buterin argued that this approach struggles at scale because of a public goods problem. Once information is revealed by a market, everyone benefits, including those who did not pay for it.

While decision markets can work in narrow cases where a single organization directly benefits from the insight, Buterin said this model is unlikely to generate large, sustainable market volumes.

Hedging as the Missing Use Case

The most promising path forward, in Buterin’s view, lies in repositioning prediction markets as generalized hedging tools.

He illustrated this with a political risk example. If it is publicly known that one political party benefits a particular industry more than another, investors can use prediction markets to offset exposure by betting against their own financial interests.

In a mathematical example, Buterin showed how a relatively small prediction market bet could materially reduce volatility in a portfolio, delivering measurable utility gains even with negative expected value.

Rethinking Stablecoins and Currency Itself

Buterin extended the idea further, questioning whether stablecoins are even the right abstraction for financial stability.

He argued that what users actually want is not a currency pegged to fiat, but assurance that they can afford future expenses. Reliance on USD-backed stablecoins, he said, undermines decentralization and fails to account for the diversity of individual cost structures.

His proposal replaces currency altogether with personalized hedging instruments.

Under this system, price indices would exist for major categories of goods and services across regions. Prediction markets would be built on these indices. Each user or business would run a local large language model that understands their spending patterns and assembles a custom basket of prediction market shares representing a fixed number of days of future expenses.

“People can hold stocks, ETH, or whatever else to grow wealth, and personalized prediction market shares when they want stability,” Buterin explained.

Why Asset-Denominated Markets Matter

For this system to work, Buterin emphasized that prediction markets must be denominated in assets people want to hold, such as interest-bearing fiat, tokenized equities, or ETH. Non-interest-bearing fiat, he argued, imposes too high an opportunity cost and overwhelms the benefits of hedging.

If built correctly, he said, such markets could attract large volumes of sophisticated capital and create a system where both sides benefit over the long term.

Mixed Reactions From the Industry

Buterin’s comments arrive as platforms like Polymarket continue to see record engagement driven largely by short-term event speculation.

Some industry participants welcomed the vision. Hilo Markets publicly praised the idea, framing it as a blueprint for a more durable financial system.

Others pushed back, arguing that speculative markets are necessary to bootstrap liquidity and attract everyday users. Buterin responded by stressing that the foundational direction of a platform matters from the outset.

A Call to Build Beyond Speculation

Buterin concluded by urging builders to think beyond engagement metrics and short-term revenue.

“Build the next generation of finance,” he wrote, “not corposlop.”

The proposal outlines a future where prediction markets are no longer treated as entertainment or gambling products, but as core financial infrastructure designed to manage real-world risk at a personalized, global scale.
