Korean Exchange KOSPI Launches Circuit Breaker

On the morning of June 5, Zcash founder Zooko released a post-mortem on the critical Orchard vulnerability. The announcement sent ZEC—Zcash’s native token—plummeting more than 30% to a current trading price of $431.64. Security researcher Taylor Hornby unearthed the critical inflation bug in Zcash’s Orchard pool on May 29, notifying the Zcash Open Development Lab (ZODL) immediately. ZODL then led an emergency coordination effort across the broader Zcash ecosystem, and the fix was finalized on June 2.

June 5 – Leading research firm SemiAnalysis published a report yesterday revealing that NVIDIA’s next-generation AI server cluster, codenamed Rubin NVL72, is undergoing a major adjustment to its memory configuration. To address supply chain bottlenecks and ensure the Rubin racks are delivered on schedule, the total capacity per individual rack has been abruptly cut from the original 55TB to 28TB. Additionally, most Rubin systems will now use 96GB SOCAMM modules instead of the initially planned 192GB units. Though SemiAnalysis founder, CEO, and Chief Analyst Dylan Patel later clarified that “this is not a disaster” and emphasized the report was never meant to stoke fear, the market reacted sharply. Micron’s shares plummeted 7.7% in yesterday’s trading, and South Korea’s SK Hynix opened down 8.32% today.

On June 5th, AAOI posted a contrarian 10% price gain yesterday. Dubbed “The Stock God,” trader Serenity commented that AAOI has been one of his go-to dip-buy positions since the stock hit $28. Driven by robust demand for its 800G and 1.6T optical transceivers, AAOI could see its stock price double—or even triple—if the company delivers on its execution goals. Additionally, should the rumored partnership with AMD and NVIDIA (NVDA) pan out, supply chain bottlenecks could push average selling prices (ASP) higher and drive margin expansion—two factors the market has not yet fully priced into AAOI’s current valuation.

On June 5, quantum computing firm Quantinuum made its public debut.

Formed via a merger of Honeywell’s quantum computing division and Cambridge Quantum, Quantinuum ranks among the world’s most highly valued quantum computing companies. The firm will trade on the Nasdaq stock exchange under the ticker symbol “QNT”.
