从资金流向来看,加密货币市场和股票市场仍然保持着高度的联动性。

从资金流向来看,加密货币市场和股票市场仍然保持着高度的联动性。

经历了一季度的调整(当时股市和加密市场都出现了明显下跌)之后,二季度开局风险偏好明显回暖。标普500指数涨幅超过12%,近期更创下历史新高;比特币也上涨了16%以上,表明市场整体已重回“risk-on”状态。

但这同时也引出一个问题:加速涌入风险资产的资金,是否正在催生泡沫?如下图所示,5月6日当天,标普500看涨期权的交易量超过2.6万亿美元,创下历史新高。

此外,看涨期权占标普500全部期权活动的近60%,这是至少七年来最高的占比。

这意味着市场投机情绪高涨,美股可能已经处于过度拉伸的状态。

事实上,有分析指出,当前美国股票的估值是150年来最贵的水平之一。P/E10比率(周期调整市盈率)目前为37.9,为历史第二高,仅次于2000年3月互联网泡沫巅峰时的44.2。

简单来说,当前股票估值比长期平均水平高出约114%。从历史经验看,这种水平之后往往伴随市场回调——而整体市场似乎已经开始更明确地定价这一风险。

这自然将注意力转向了加密市场。到目前为止,加密市场与股市基本同步波动,资金在相似的流动性和风险偏好条件下在各类风险资产之间轮动。

如果股市估值出现修正,那么这种下行压力是否会通过流动性收紧和风险敞口收缩传导至加密市场?

联动并非巧合?

从技术层面看,加密资产似乎已经跟随股市的步伐。

在期权活动大幅飙升之后,5月7日标普500收盘下跌0.38%,与比特币1.7%的回调形成对应。

不过从宏观层面来看,这次回调的幅度仍然相对有限。目前还不足以将其解读为明确的警示信号。

然而,链上数据已经显示出市场状况走弱的早期迹象。

如下图所示,比特币的Coinbase溢价指数已连续超过10个交易日处于负值区间,这表明来自美国机构参与者的持续卖压或现货需求疲软。

本质上,美股估值过高与美国本土加密需求走弱这两件事并存,恐怕并非巧合。

相反,这表明机构参与者可能已经在降低风险敞口,导致资金流向变得越来越偏向防御——即使价格仍维持在相对高位。

从技术角度看,这种转变增加了整体风险资产正在进入潜在泡沫周期后半段的可能性。

因此,一旦股市出现回调,这种压力很可能会溢出到加密市场。而当前防御性的资金布局,正是风险偏好减弱的早期预警信号。

总结

股票与加密市场在强劲的风险偏好资金推动下同步上行。

比特币需求疲软释放出越来越高的谨慎信号,一旦股市回调,溢出风险将随之上升。

GPT-5 Also Has Tip-of-the-Tongue Moments, Google Tested 4.5 Million Times: The Keys Are Lost

Google researchers have discovered that advanced AI models like GPT-5 and Gemini 3 experience a phenomenon akin to the human "tip-of-the-tongue" state, where they possess knowledge but fail to retrieve it. Their study, "Empty Shelves or Lost Keys?" (ICML 2026), introduces the "Knowledge Portrait" framework to analyze factual knowledge in models, distinguishing between failure to encode a fact versus failure to recall it. Testing on 13 models across 2.15 million queries from the WikiProfile benchmark revealed that state-of-the-art models successfully encode 95-98% of facts into their parameters. However, when asked directly, they fail to recall 26-34% of these known facts. Enabling chain-of-thought ("thinking") reasoning reduces this recall failure to 11-12%, recovering 40-65% of the previously unrecalled but encoded facts. The research identifies two key bottlenecks: recalling obscure ("long-tail") facts and answering reversed queries (e.g., "Who is Tom Cruise's mother?" vs. "Whose son is Tom Cruise?"). While scaling model size effectively reduces encoding failures, it does little to improve recall rates. In larger models, recall failure becomes the dominant source of factual errors, accounting for over 70% of mistakes in GPT-5.2. The findings suggest that for top models, the primary challenge is no longer storing knowledge but accessing it efficiently. Future accuracy gains may depend more on improved inference-time methods and "meta-cognitive" abilities, enabling models to recognize when they need to engage in deeper reasoning to retrieve information they already know.

The Dollar is a Technology: Stablecoins Are Exporting U.S. Institutions to the World

This article argues that stablecoins and blockchain infrastructure are becoming a vehicle for exporting American financial systems globally. The core thesis is that the U.S. dollar, as a "technology," is increasingly embedded in blockchain rails, moving beyond a reserve currency to represent the institutional stability of the United States itself. The piece highlights three key areas where this is happening: 1. **Cross-border payments and trade finance:** Companies like Keyrails use stablecoins and blockchain to streamline and secure trade finance for emerging markets (e.g., Nigeria-China trade), offering faster, often cheaper dollar liquidity than traditional systems. 2. **Programmable collateral and credit:** Platforms like SemiLiquid allow institutions to use tokenized assets (e.g., treasuries, stocks) as "programmable collateral" for loans without moving them from custody, unlocking capital efficiency and improving transparency in institutional lending. 3. **Financing real-world assets:** Protocols like USD.AI create lending markets for productive, hard-to-finance assets like AI GPUs, connecting global stablecoin liquidity to physical capital. The author concludes that the true value of these new blockchain-based financial platforms lies not just in transaction volume, but in the deep, hard-to-replicate "context" (data, trust, operational knowledge) they build around specific economic activities like trade and asset finance. This represents crypto's evolution into an operating system for real-world capital formation, moving beyond speculation.

Ethereum Glamsterdam Upgrade: Largest-Scale Underlying Restructuring Yet, Mainnet Date Still Undecided

The upcoming Ethereum "Glamsterdam" upgrade is viewed by core developers as the most significant protocol-level refactoring since The Merge, fundamentally altering how the network processes transactions and manages its state to advance L1 scaling. Its core goals are: accelerating processing via parallelization, increasing capacity, and enhancing sustainability through adjusted fees that better reflect long-term data storage costs. The upgrade features two headline proposals. First, **ePBS (EIP-7732)** on the consensus layer aims to formalize proposer-builder separation directly within the protocol, eliminating reliance on off-chain relayers. This built-in mechanism is designed to provide a more secure and efficient block production pipeline, extending the critical validation window to allow the network to handle more data, particularly for Layer2s. Second, **BALs (EIP-7928)** on the execution layer introduces block-level access lists. These lists specify the data each transaction will access beforehand, allowing the network to identify and safely execute non-conflicting transactions in parallel, rather than strictly sequentially. This also speeds up new node synchronization. Glamsterdam also includes配套 proposals to reprice storage costs (aiming for a predictable ~120 GiB annual state growth) and the cost of data-reading operations to better align with modern hardware costs and prevent spam. Regarding the timeline, the initial schedule targeting a mainnet activation on September 16, 2026, has likely been delayed. Following the launch of a new dedicated testnet (Plataberget), the deployments on the Sepolia and Holesky testnets are now expected in September, with the mainnet launch potentially pushed to Q4 2026 or later, as developers prioritize correctness over a fixed date.
