For most of the past three years, the so-called "Big Seven" (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla) led the stock market rally. But this trend reversed at the end of 2025 as Wall Street began to question the hundreds of billions of dollars these companies had invested in developing artificial intelligence and when those investments would pay off. An index tracking the Big Seven hit a record high on October 29, and since then, five of the Big Seven companies have seen their share prices decline and lag behind the S&P 500. During this period, only Alphabet and Amazon, with gains approaching 20%, have maintained their upward momentum. Darrell Cronk, chief investment officer at Wells Fargo Wealth & Investment Management, said, "Tech stocks have become a 'performance-driven' story. If big tech companies continue to deliver strong results, I think money will flow back into the tech sector." Next week, Microsoft, Apple, Tesla, and Meta will release their earnings reports, providing insights into the health of industries ranging from cloud computing and electronics to software and digital advertising.

a16z Crypto has released an analysis suggesting that concerns about quantum computing threatening cryptocurrencies are often exaggerated. According to PANews, the likelihood of a quantum computer capable of causing real-world disruption emerging before 2030 is very low. The article highlights that mainstream digital signature schemes and zero-knowledge systems like zkSNARKs are not easily susceptible to quantum attacks that follow a 'collect now, decrypt later' model. Prematurely transitioning blockchain systems to quantum-resistant solutions could introduce performance issues, engineering immaturity, and potential security flaws. a16z further emphasizes that compared to the yet-to-materialize quantum risks, major public blockchains like Bitcoin and Ethereum currently face more immediate challenges. These include the complexity of protocol upgrades, governance issues, and vulnerabilities in implementation layer code. The firm advises developers to plan quantum-resistant paths based on a reasonable assessment of timeframes rather than rushing into migrations. It also notes that in the foreseeable future, traditional security issues such as code defects, side-channel attacks, and fault injections should take precedence over quantum computing concerns. Resources should be focused on enhancing audits, fuzz testing, and formal verification.

a16z Crypto published a lengthy article on the X platform, pointing out that the timeline for the emergence of a quantum computer capable of cracking cryptocurrencies (CRQC) is often exaggerated, and the likelihood of it appearing before 2030 is extremely low. The risk profiles of different cryptographic primitives vary. Quantum-resistant encryption faces "capture-before-decrypt" (HNDL) attacks and requires immediate deployment. Quantum-resistant signatures and zkSNARKs, however, are less susceptible to HNDL attacks; premature migration could lead to performance overhead, immature implementation, and code vulnerabilities, thus requiring a cautious rather than hasty migration strategy. For blockchains, most non-privacy public chains such as Bitcoin and Ethereum primarily use digital signatures for transaction authorization, thus posing no HNDL risk. Their migration pressure mainly stems from non-technical challenges such as slow governance, social coordination, and technical logistics. Bitcoin faces unique issues including slow governance and the existence of millions of quantum-fragile tokens worth hundreds of billions of dollars that could be abandoned. In contrast, privacy chains, due to the encryption or hiding of transaction details, do face HNDL attack risks and should transition as soon as possible. a16z Crypto emphasizes that in the coming years, implementation security issues such as code vulnerabilities, side-channel attacks, and fault injection attacks pose a more pressing and significant security risk than the threat of distant quantum computers. Developers should prioritize investing in code auditing, fuzzing, and formal verification.
