原标题:为什么预测市场真的不是博彩平台


(注:本文讨论的监管框架、市场分类与法律环境,均基于美国(尤其是联邦与州)监管体系,与其他国家或地区的法律环境无关。)

过去两年,预测市场(Prediction Markets)从加密圈的边缘概念快速进入主流科技创投与金融资本视野。

合规新贵 Kalshi 近期完成 10 亿美元 E 轮融资,投后估值升至 110 亿美元,投资阵容包括 Paradigm、Sequoia、a16z、Meritech、IVP、ARK Invest、CapitalG、Y Combinator 等最具话语权的资本。

赛道龙头 Polymarket 则以 90 亿美元估值获 ICE 战略投资,又以 120 亿美元估值由 Founders Fund 领投一轮 1.5 亿美元融资,目前更以 150 亿美元估值继续募资。

资本如此密集涌入,但每当我们发布预测市场的深度文章,评论区依然免不了一句:“不过是博彩换皮而已”。

诚然,在体育等极易被对比的赛道,预测市场和博彩平台在表面玩法上确实有相似之处。但在更本质、更广义的层面上,两者在运行逻辑上存在结构性的差异。

更深层次的现实是:有了一线资本的入局,它们会推动把这种“结构性差异”写入监管规则,成为新的行业语言。资本押注的不是博彩,而是事件衍生品交易所(DCM) 这一全新资产类别的基础设施价值。

从监管逻辑来看:

美国的博彩市场 = 州级监管(个体差异极大)、税高(甚至是很多州的重要财政来源)、合规极重、限制极多;

新的预测市场 = 金融衍生品交易所,联邦监管(CFTC/SEC)、全国通行、规模无限、税制更轻。

一言以概之:资产类别的边界,从来不是学术讨论和哲学定义,而是监管与资本的权力分配。

何为结构性区别?

先把客观事实讲清楚:为什么预测市场不是博彩?因为它们在最底层的机制上,是两个完全不同的系统。

1. 价格形成机制不同:市场 vs 庄家

本质来说透明度不同:预测市场有公开订单簿,数据可审计;博彩赔率内部计算不可见,平台可随时调整。

● 预测市场:价格由订单簿(order book)撮合,采用金融衍生品的市场化定价,由买卖双方决定价格。平台不设概率,也不承担风险,只收取交易费用。

● 博彩平台: 赔率由平台设定,内置庄家优势(house edge)。无论事件结果如何,平台通常在概率设计中保持盈利安全区间。平台的逻辑是“长远必胜”。

2. 用途差异:娱乐消费 vs 经济意义

预测市场所产生的真实数据具备经济价值,并在金融决策上用于风险对冲,甚至有可能反向作用到真实世界,例如媒体叙事、资产定价、企业决策、政策预期。

● 预测市场:预测市场能够生成数据型产品:比如用于宏观事件概率判断,舆情与政策预期,企业风险管理(天气、供应链、监管事件等),金融机构、研究机构、媒体的概率引用标的,甚至可以作为套利与对冲策略的判断基础。

最知名的案例当然就是美国大选时,不少媒体引用 Polymarket 数据作为民调参考之一。

● 博彩平台: 单纯的娱乐化消费,博彩赔率 ≠ 真实概率,没有数据外溢价值。

3. 参与者结构:投机性赌客 vs 信息套利者

博彩的流动性是消费,预测市场的流动性是信息。

● 预测市场:用户包含数据模型研究者、宏观交易员、媒体与政策研究人员、信息套利者、高频交易者、机构投资者(特别是在合规市场中)。

这决定了预测市场的信息密度高、并具有前瞻性(例如选举夜、CPI 公布前)。流动性是“主动的、信息驱动的”,参与者是为了套利、价格发现、信息优势而来。流动性本质是 “信息流动性(informational liquidity)。

● 博彩平台:主要为普通用户,容易情绪投注,并被偏好驱动(loss chasing / gambler fallacy),例如支持“自己喜欢的选手”,押注不基于严肃预测,而是情绪或娱乐。

流动性缺乏方向性价值,赔率不会因为“聪明钱”而更准确,而是因为庄家的算法调节。 不产生价格发现,博彩市场不是为了发现真实概率,而是为了平衡庄家的风险,本质是 “娱乐消费流动性”。

4. 监管逻辑:金融衍生品 vs 区域博彩业

预测市场:Kalshi 在美国被 CFTC 认定为 事件衍生品交易所(DCM),金融监管关注重点是市场操纵、信息透明、风险暴露,预测市场遵循金融产品税制。同时预测市场正如加密交易平台,天然可全球化。

博彩平台:博彩属于州博彩监管机构,博彩监管重点是是关注消费保护、赌博成瘾、创造地方税收。博彩需缴纳博彩税、州税。博彩严格受限于地区牌照体系,是区域化业务。

二、最容易“看起来相似”的例子:体育预测

很多文章在聊预测和博彩的区别是总是只注重在预测政治走向、宏观数据等具备社会属性的例子,这部分是和博彩平台完全不同的,大家也容易理解。

但本文,我想举一个最容易被诟病的例子,就是开头提到的“体育预测”,在很多球迷眼里,预测市场和博彩平台在这部分看上去没差。

但实际上,二者的合约结构不同。

现行预测市场中是 YES / NO 二元合约(binary contracts),比如:

湖人是否会在本赛季赢得总冠军?(Yes/No)

勇士是否会在常规赛拿到 45 胜以上?(Yes/No)

或者是 离散区间(range contracts):

“球员得分是否 >30?”(Yes/No)

本质上是标准化的 YES/NO,每个二元金融合约是独立市场,结构有限。

博彩平台的合约可以无限细分、甚至自定义,比如:

例如具体比分、半场 vs 全场、几号球员罚球线投篮几次、总三分球数、二串一、三串一、自定义串关、让分、大小、单双、球员个人表现、角球数、犯规数、红黄牌、伤停时间、ive betting(实时每分钟盘口)…

不仅无限复杂,甚至是高度碎片化的事件树(event tree),本质上是无限参数化的细粒度事件建模。

因此,即使在这种看似相同的题材上,机制差异也就造成了我们前面所讲的四大结构性区别。

在体育事件上,预测市场的本质依然是orderbook、由买卖双方形成、市场驱动,本质上更像期权市场。在结算规则也只使用官方统计数据。

而在博彩平台中,赔率永远是:庄家设定 / 调整、内置 house edge、目标是“平衡风险、保证庄家收益”。在结算上有盘口解释权、赔率带有模糊空间,甚至在碎片化事件上不同平台结果可能都不同。

三、 终极问题:一场关于监管归属的权力重划

资本之所以在预测市场上快速押注数十亿美元,原因并不复杂:它看中的不是“投机叙事”,而是一个尚未被监管正式定义的全球事件衍生品市场——一个有潜力与期货、期权并列的新资产类别。

而困住这个市场的,是一项陈旧而模糊的历史问题:预测市场到底算金融工具,还是算博彩?

这条线没画清楚,市场就跑不起来。

监管归属决定产业规模,这是华尔街的旧逻辑,却刚刚被应用到这个新赛道上。

博彩的天花板在州一级,这意味着碎片化监管、沉重税负、合规不统一、机构资金无法参与。 其增长路径先天受限。

预测市场的天花板则在联邦。一旦被纳入衍生品框架,它便可以复用期货和期权的所有基础设施:全球通行、可规模化、可指数化、可机构化。

届时,它不再是一个“预测工具”,而是一整套可交易的事件风险曲线。

这也是为什么 Polymarket 的增长信号如此敏感。2024–2025 年间,其月成交量多次突破 20–30 亿美元,体育类合约成为增长核心之一。这并不是“蚕食博彩市场”,而是直接争夺传统 sportsbook 的用户注意力——而在金融市场,注意力迁移往往是规模迁移的前兆。

各州监管机构极度抗拒让预测市场被划入联邦监管,因为这意味着两件事同时发生:博彩用户被吸走、州政府的博彩税基被联邦直接截走。这不仅是市场问题,而是财政问题。

一旦预测市场归入 CFTC/SEC,州政府不仅失去监管权,还失去“最容易征收、最稳定”的地方税之一。

近期,这场博弈已开始公开化。Odaily 星球日报报道,纽约南区法院已受理集体诉讼,指控 Kalshi 在未取得任何州博彩牌照的情况下销售体育类合约,并质疑其做市结构“让用户实质上与庄家对赌”。数日前,内华达博彩管理委员会也称 Kalshi 的体育“事件合约”本质上属于未经许可的博彩产品,不应享有 CFTC 的监管庇护。联邦法官 Andrew Gordon 更在听证会上直言:“在 Kalshi 出现之前,没人会认为体育赌注属于金融商品。”

这不是产品争议,这是监管权属与财政利益的冲突和对定价权的争夺。

对资本来说,背后的问题不在于预测市场是否能增长;而在于,它会被允许增长到多大。

Tsinghua AI Mathematician Emerges: From Intuition to Theorem, Contributing to an 84-Page Quantum Algorithm Paper

Tsinghua University’s Intelligent Industry Research Institute (AIR) has developed an AI mathematician agent named AIM, designed not just to solve math problems but to actively participate in early-stage research. In a recent study, researchers collaborated with AIM to develop "Sign Embedding Quantum Algorithms," resulting in an 84-page paper on quantum algorithms for matrix equations and functions. The research began with a human researcher's intuition: can rational approximation serve as a design principle for quantum algorithms? AIM helped expand this idea into multiple candidate research directions. Human researchers then filtered and focused on the most promising path. AIM assisted in organizing theorems, generating proof drafts, and performing complexity analysis, while humans maintained oversight, auditing assumptions and refining derivations. This case illustrates a human-AI collaborative workflow: AI rapidly explores and expands research avenues, generates draft materials, and aids in checking derivations; human researchers provide critical judgment on direction, value, and validity. The process emphasizes "high-throughput candidate generation + human value gating + AI-assisted audit and repair + human final integration." The resulting quantum algorithm framework offers a unified approach to several matrix problems, advancing quantum linear algebra under more general conditions. This work suggests AI's role in theoretical research is evolving from task-specific assistance to supporting the entire research lifecycle—enhancing exploration and efficiency while keeping human expertise central to guiding inquiry and ensuring rigor. *Paper & System Links:* - AIM application report: https://arxiv.org/abs/2606.24899 - Quantum algorithm paper: https://arxiv.org/abs/2604.25333 - AIM repository: https://github.com/TheoryFoundry/AIMv2

Short-Lived Meme Mania: Can It Be the Icebreaker for Robinhood's RWA Narrative?

Robinhood recently launched its own Layer 2 network, Robinhood Chain, built on Arbitrum and focusing on tokenized stocks, RWA, DeFi, and AI finance. Shortly after launch, a meme coin called CASHCAT, named after an early unused Robinhood brand, surged in popularity, achieving a market cap near $150 million and high daily trading volume. It gained traction through third-party DEXs and launchpads like Uniswap and Noxa.fun, bypassing Robinhood's official listing process. This highlights a key feature of the permissionless chain: even assets not officially approved can achieve significant liquidity and trading activity. While CASHCAT currently dominates the chain's meme coin sector, its high turnover indicates speculative trading. The rapid proliferation of new meme coins risks dispersing liquidity. Meanwhile, the chain's core RWA sector remains relatively small at $12.5 million. CEO Vlad Tenev has expressed that the chain is well-suited for both RWA and meme coins. In the optimistic scenario, meme-driven activity could bootstrap the chain's user base and liquidity for its long-term RWA vision. However, if the meme frenzy fades quickly, the RWA narrative may struggle to gain traction independently. The incident demonstrates that on a permissionless platform, the market itself can create major assets, offering Robinhood a potential new growth avenue beyond its core crypto business as it navigates the long-term development of the tokenized asset market.

The Fall of Zapper: An Act of God or a Human Error?

The Fall of Zapper: A Post-Mortem of a DeFi Pioneer In July 2026, Zapper, a once-dominant DeFi portfolio tracker, announced its shutdown. Born in 2020 from a merger, Zapper capitalized on the DeFi Summer boom, reaching 2 million monthly users and processing over $13B in transactions, backed by $16.5M in funding from investors like Framework Ventures and Coinbase Ventures. Its core "Zap" feature simplified complex multi-step DeFi operations. Despite its early success, Zapper failed to build a sustainable business model. Revenue from DEX aggregation was minimal due to fierce competition, while maintaining its multi-chain data infrastructure was costly. Furthermore, the DeFi landscape shifted: capital consolidated around top protocols, reducing the need for complex portfolio tracking across numerous platforms. Zapper's user base and core demand eroded. The company attempted multiple pivots, including an NFT-based points system, a social app (Chainchat), and plans for a ZAP token protocol. However, these initiatives—often focused on creating new, speculative C端需求 rather than solving existing pain points—ultimately failed. Critics argue Zapper remained trapped in a "blockchain purist" mindset, prioritizing costly, non-revenue-generating features over its competitive DEX aggregator. Unlike competitor DeBank, which successfully pivoted to its Rabby Wallet, Zapper lacked a diversified revenue stream. Its closure highlights the peril for tooling projects that fail to adapt to market shifts and monetize effectively, serving as a cautionary tale for the industry.
