Abstract

同一事件在不同平台的定价会不同,这就是机会所在。

编译:Luffy,Foresight News


大多数人在预测市场上赌博,而我在预测市场上套利。以下是我从分散、低效的预测市场中赚取 10 万美元的具体策略。


第一步:理解游戏规则


预测市场允许你对现实事件的结果下注,例如:

  • 「以太坊年底前会涨到 5000 美元吗?」
  • 「MrBeast 会竞选总统吗?」
  • 「Kanye West 会发行代币吗?」

每个市场都有不同的用户群体,每个群体都有各自的偏见。这意味着同一事件在不同平台的定价会不同,而这正是机会所在。


案例:如果平台 A 的 「会」 报价 0.4 美元,平台 B 的 「不会」 报价 0.55 美元,那么无论结果如何,你都能锁定 0.05 美元的利润,这就是套利。


第二步:寻找你的优势


对我最有效的策略是多结果市场,这类市场最容易出现定价错误。
示例:

  • 本周末 F1 谁会夺冠?
  • 英国大选哪个政党会赢?
  • 《恋爱岛》下一个被淘汰的是谁?

理论上,所有结果的概率之和应为 100%,但现实中常出现总和达 110% 的情况。
原因:平台通常会收取隐性费用(「超额溢价」),且赔率由用户决定,导致大量低效定价。


第三步:如何判断是否存在套利机会


核心规则:

  • 找到不同平台上的同一事件;
  • 为每个结果选择最低价格;
  • 若总价格低于 1 美元,即可套利。

真实案例:下一任教皇是谁?
两个平台的报价如下:


策略是买入所有结果,其中必定有一个会实现,这样可以确保获得 1 美元。每笔交易利润为 0.021 美元(2.1% 无风险回报),这就是套利。你不是在赌谁会成为教皇,而是在赌两个平台无法就谁会成为教皇达成一致。 而当他们意见不一致时,你就能赚钱。
Myriad 的流动性要差得多,但还有另外两个网站的价差更接近。 如果你关注更多的市场,你会发现更大的优势。


我通常只在 APY 高于 60% 时才进行套利(APY =(利差 / 解决天数)× 365)。
本例中,事件 29 天后结束:


(0.021 / 29) × 365 ≈ 26.4% APY(低于我的门槛 60%,放弃)。
若事件在 7 天后结束:


(0.021 / 7) × 365 ≈ 109.5% APY(果断入场)。


第四步:与时间赛跑


预测市场套利是延迟游戏:


价格出现差异后,通常只有几分钟的时间窗口,而非几小时;谣言传播、平台更新滞后等都会导致价差,而你的优势仅存在于这段时间。


如果可以的话,请将这一部分自动化,在 Discord、Telegram 和 Twitter 上使用价格提醒。 有时我仅凭肌肉记忆就能发现价差。 行动越快,赚得越多。 犹豫 5 分钟,价差就消失了。我所取得的最佳利差是 18%,利润相当可观。


需要提醒的是,确保各平台有可用资金,并清楚手续费。


第五步:提前退出


多数人等结果揭晓,而我在结果明确前就获利了结。


假设我以 0.94 美元买入所有结果,这样我就拥有 0.06 美元价差。我不需要等待结果,如果市场收紧,我可以以 0.98 或 0.99 美元的价格出售,我就会退出。
这样可以大幅提升 APY,快速切换到下一个市场。
额外提示

  • 寻找重叠事件:例如 「特朗普赢得 2024 大选」 与 「共和党胜选」 可能存在隐藏套利;
  • 瞄准小市场:定价错误更多,竞争更少;
  • 利用小众平台:价差更大,可能有空投奖励;
  • 细读结算规则:一个词可能改变结果;
  • 仔细校验:确认订单簿、成交价,计算包含所有手续费。

总结
我用 2 个多月赚到 10 万美元,期间有平淡,也有忙碌。波动性越大,价差越多,但即使市场平静,也永远有下一个低效市场等待发现。

The Largest Upgrade Since The Merge? How Glamsterdam Will Affect Ethereum?

Ethereum's next major upgrade, Glamsterdam (combining consensus layer "Gloas" and execution layer "Amsterdam"), is scheduled for late 2026 and considered the most significant overhaul since The Merge. It aims to fundamentally enhance L1 performance and architecture to prepare for substantial capacity increases. The upgrade centers on three core changes: 1. **Enshrined PBS (ePBS - EIP-7732):** Integrates the Proposer-Builder Separation directly into the protocol, eliminating reliance on external relays. This extends the window for processing execution payloads, allowing nodes more time to handle larger blocks and more data, paving the way for a higher Gas Limit. 2. **Block-Level Access Lists (BALs - EIP-7928):** Provides a pre-declared "map" in the block header of all state data (accounts, storage) that transactions will access and modify. This enables potential parallel transaction processing and faster state synchronization for nodes. 3. **Gas Repricing (EIP-8037):** Overhauls the gas model to more accurately reflect the real resource costs for nodes. It separates computation costs from state storage costs, making operations that create permanent state data (like new accounts) more expensive, while computation-heavy operations become relatively cheaper. These changes work together to solve the trilemma of scaling: giving nodes more time to process larger blocks (ePBS), reducing execution bottlenecks (BALs), and controlling unsustainable state growth (Gas Repricing). The goal is a credible path to a higher Gas Limit (e.g., 200M gas) without compromising decentralization by overburdening node hardware. For users: * Transaction fees for simple transfers may decrease and become more stable due to increased block space, but state-intensive operations (contract deployment) may cost more. * Gas estimation by wallets will improve in accuracy. * L2 data posting costs could become more stable long-term due to increased Blob capacity. * EIP-7708 will standardize logs for ETH transfers, improving tracking for wallets and exchanges. Node operators must upgrade clients, but ETH holders need take no action. In essence, Glamsterdam doesn't just raise the block size limit; it re-engineers Ethereum's core block production, execution, and economic models to enable sustainable, decentralized scaling.

Robinhood Chain Mainnet Goes Live: Can Stocks Finally Be Moved Into Wallets?

Robinhood has officially launched its public mainnet, Robinhood Chain, along with stock-like tokens, the USDG yield product, and a DeFi lending portal. This marks a significant shift where a major online broker is integrating its user interface, regulatory compliance, self-custody wallet, and on-chain protocols into a single, streamlined experience. The goal is to simplify access to stock exposure, stablecoin yields, collateralized lending, and AMM trading for mainstream users. Eligible non-U.S. users can hold these "Stock Tokens"—structured as tokenized debt securities—in the Robinhood Wallet for 24/7 exposure to assets like U.S. stocks or ETFs. U.S. users can access an estimated ~7% APY on dollar-backed USDG through the Robinhood Earn program via self-custody wallets, with lending infrastructure powered by Morpho protocol. Built as a Layer 2 on Arbitrum, Robinhood Chain leverages existing DeFi protocols like Uniswap. The core strategy is not to reinvent DeFi but to channel Robinhood's large traditional finance user base (27.4 million funded customers as of Q1 2026) into on-chain finance, lowering the technical barriers. However, key limitations exist. The stock tokens are not direct equity ownership and are unavailable in the U.S. and some jurisdictions due to regulatory constraints. The ~7% yield is variable and carries inherent DeFi risks, not guaranteed principal protection. Furthermore, while AMMs enable trading, price discovery for major stocks will likely remain anchored in traditional markets like NASDAQ for the foreseeable future. Ultimately, Robinhood Chain is an early experiment in "on-chain brokerage." Its success will depend on real-world metrics like trading volume, sustained user migration to self-custody, stable yield performance, and regulatory feedback, rather than its launch narrative.

Circle CEO Responds to OUSD Challenge: Stablecoin Market Is 'Winner-Takes-All', Consortium Model Doomed to Fail

Circle CEO Jeremy Allaire addresses market concerns following the announcement of the Open USD (OUSD) stablecoin project backed by 140 global companies. Allaire argues the stablecoin market exhibits "winner-takes-all" dynamics due to powerful network effects. He cites USDC's near-decade lead in three key areas: 1) **Application Integration & Protocol Development**: Thousands of integrated services and protocols (like CCTP) create utility and lock-in for developers and users. 2) **Liquidity Network Effects**: A deeply embedded, globally distributed liquidity infrastructure across primary and secondary markets, built over years. 3) **Regulatory Integration**: Extensive licensing and compliance groundwork ensuring USDC's acceptance in major markets like Europe and Japan. Allaire challenges OUSD's proposed advantages. He contends that promises of free redemption, while appealing, face market realities where such models can become exit routes for other stablecoins. He also questions the feasibility of fully distributing all revenue to an alliance, stating it would "starve" the critical infrastructure investments needed for scale and utility. Furthermore, he expresses skepticism about large alliance governance models, noting they often lead to slow decision-making and misaligned incentives. While welcoming OUSD to the ecosystem, Allaire reaffirms confidence in USDC's dominant position, backed by its long-term infrastructure investments and strong partnerships, including its ongoing collaboration with Coinbase.
