Polymarket V2 升级后出了个 Bug：一些不活跃的钱包一登录，就提示生成新钱包，一旦点了 Deploy，老钱包及其交互记录可能直接失效

就算以后 Bug 修复，取回资金是小事，但老钱包的交互记录能不能算进空投才是大事！想到这，我坚决不冒险点 Deploy

好消息是，解决办法超简单：浏览器里把 Polymarket 相关缓存全删掉，重新登录就立刻搞定！✅

这篇论文，研究了 Polymarket 140 万用户、7000 万笔交易。70.8% 的人在亏钱，总结出【亏钱四件套】👇

1/ 押冷门！？
平均用户 63% 的交易集中在 <10¢ 或 >90¢ 的极端价格。
买 5¢ 的合约感觉赔率诱人，赢一次赚 20 倍，多爽.
问题是，这恰恰是长期期望值最负的区域。你以为在捡漏，其实是在给概率幻觉批发市场交学费
买 5¢ 的东西，它真实的概率可能只有 2¢🤷‍♂️

2/ 只打市价单（做taker）
从纯 taker 变成纯 maker（挂限价单），亏损概率下降 36 个百分点--论文里最猛的单一信号
量级是其他���有变量的 10 倍以上
你每次着急地市价成交，都在给耐心挂单的人发工资🤷‍♂️

3/ 交易太频繁
交易次数每上一个量级，亏损概率增加 5 个百分点
过度交易 = 过度自信
除非你是Bot🤷‍♂️

4/ 只玩单一品类
只赌政治、或者只盯着某支球队的人，亏损概率高 13.6 个百分点
品类集中 = 暴露在相关风险里，也是”我只懂这个”的错觉信号🤷‍♂️

那赢家是谁？
前 1% 的用户拿走了 84% 的全部盈利
前 0.1% 拿走了 58.5%
论文用超额命中率证明：人家是真有本事，不是运气好。

Jeff Yass, the legendary founder and Managing Director of Susquehanna International Group (SIG), shared his vision for prediction markets.

The Core Value: Obtaining Accurate Probabilities

Yass asserts that prediction markets add "tremendous value to the world." He stresses that you basically can’t make a good decision without knowing the probabilities of events happening. Prediction markets are the best known way to get the most accurate guess of those predictions.

From a broader perspective, Yass sees them improving decision-making in business and government by revealing the power of incentives and information.

The Antidote to Political Lies

Yass’s primary motivation for championing prediction markets is to get the truth out there, calling them the "antidote" to systemic political manipulation. Prediction markets provide an objective, trusted source, because anyone betting incorrectly will lose money.

He cites the Iraq War as the perfect example. When George Bush initially estimated the cost at $20 billion, an advisor who estimated $50 billion was punished. The true cost ended up between $2 trillion and $6 trillion. Had a prediction market existed, the price would have been substantially higher than $50 billion—perhaps $500 billion. Seeing that gigantic number would have created much more public pushback against the war.

He explains that while the public might not know the cost of a war, a small group of experts would bet on the market, bidding the price up to a sensible level. This gives the public more trustworthy information than a politician who is "making up a number or purposely lying."

Transforming Business, Insurance, and Policy

Prediction markets extend far beyond curbing political lies:

1. Guiding Business Decisions and Hedging:
SIG constantly monitors the odds of events like presidential elections to determine if a stock has overreacted or underreacted to political outcomes.

For major business decisions—like moving an operation to a new city—prediction markets can instantly provide the probability of an election outcome (e.g., a candidate having a 90% chance to win), which is nearly impossible to ascertain just by reading the news. A developer concerned about real estate value dropping if a certain person wins can use the market to hedge, essentially buying insurance.

2. Revolutionizing Insurance:
Prediction markets could profoundly influence the insurance business by making it cheaper and more bespoke. In areas where traditional insurance is impossible to get (like parts of Florida due to rate caps), markets could offer targeted protection.

For example, a market could be created asking, "Will winds exceed 80 mph in your area in the next two days?" If the probability is 10%, a person could bet $10,000 to win $90,000 to cover potential damage. This structure removes the high costs of administrative claims and advertising, making insurance much more quantifiable and affordable.

3. Accelerating Policy Change:
Yass points to driverless cars. While people fear robot malfunctions, roughly 40,000 Americans die in car accidents annually. He estimates driverless cars could reduce this by 75%, saving 30,000 lives. If a prediction market quantified the vastly lower number of car accident deaths expected by 2030, policymakers would be forced to "hustle and hurry up" deployment, driven by objective data.

Evolution and Overcoming Obstacles

Currently, prediction markets are mainly a "bespoke product" driven by smaller retail players. Large institutions like Goldman Sachs or Morgan Stanley are still hesitant. Yass believes that as regulatory clarity emerges, Wall Street-sized bets will appear, with liquidity coming from both massive firms and retail flows.

On Market Manipulation: Yass is unconcerned about systemic manipulation. He explains that any attempt to maliciously manipulate a price would require the bad actors to lose vast amounts of money. If someone tries to bet the cost of a war is too low, competitive firms like SIG would bet "hundreds of millions of dollars" against them. The cost to manipulate is extremely high, protecting the market’s integrity.

The Biggest Obstacle: The main challenge is psychological fear. People tend to overstate the downside risks of prediction markets while ignoring the problems already going wrong with the current system. Yass is optimistic that this fear will dissipate as people recognize the value and economic savings the markets provide.

The Philosophy of Probability and Life Decisions

Yass, a former professional gambler, emphasizes the importance of probability in every aspect of life.

His single message to the world about prediction markets is:
“My mother used to say to me, ‘If you're so smart, how come you're not rich?’ Prediction markets are objective. If you think the odds are incorrect, then go bet it and put it back where it should be. If you're really smarter than the markets, you'll make a lot of money [and] do society a favor. If you can't make money, you may want to consider being quiet, because maybe the market knows more than you do.”

He recounts an example where his 12-year-old daughter, checking the odds on a trading market, had a more accurate prediction (22%) of Obama winning a primary than one of the world’s foremost political scientists.

Advice for Students: Yass strongly urges students who want to be decision-makers under uncertainty to study probability and statistics. He criticizes the current education system for prioritizing calculus—a subject few use daily—over probability and statistics, which is essential for interpreting world events and distinguishing "signal versus the noise."

On Major Life Decisions: Yass notes a paradox: the bigger the decision, the less time we spend thinking about it. People worry endlessly about minor things (like buying a stock) but "plop into" life-altering choices (like who to marry) without much thought.

He suggests applying a market mechanism to major personal decisions. For instance, in a romantic relationship, he suggests finding a mechanism to anonymously ask friends for an honest market judgment: "Is this person too nutty for me to be going out with?" This external, objective feedback can help prevent many "horrible relationships" from happening.
