The hidden debt of the five major U.S. tech giants has surged to 1.65 trillion U.S. dollars.

AMD will host its Advancing AI event in San Francisco from July 22 to 23, where more details about its MI500 series GPUs and scale-up Co-Packaged Optics (CPO) roadmap are set to be unveiled. In response to community queries, Serenity noted that if AMD explicitly commits to a CPO solution and discloses its optical engine supplier at the event, it will be a major positive for the entire CPO ecosystem—meaning NVIDIA is no longer the sole player driving the optical interconnect transition. Jefferies analyst Blayne Curtis currently expects AMD to partner with Astera Labs on UAL and Broadcom on ESUN, but the key watchpoint is whether AMD will officially shift to a CPO-based scale-up design and who will supply the optical engine. Serenity added that a clearer supply chain picture will only emerge after the event (held Wednesday and Thursday), so conclusions are premature for now. For Sivers, its supply chain ties to AMD’s CPO plans can only be inferred indirectly at present: first, GlobalFoundries (GF) is rumored to be involved in AMD’s MI500 CPO work, and Sivers is GF’s reference laser supplier; second, AMD has previously invested in Ayar Labs. If AMD confirms at the event that it will use Ayar Labs or GF’s SCALE as the optical engine for the MI500 CPO, it will be a massive boost for Sivers, which holds a core role as an upstream laser and reference laser supplier in both potential paths. The upcoming MI500 is expected to adopt a native UAL scale-up architecture, supporting 256 GPUs per rack and interconnected via optical links. Sivers has been steadily securing positions across multiple tech tracks this year, including CPO, pluggable optical modules, and silicon photonics. If AMD’s event confirms Sivers’ indirect entry into the supply chain, it will further validate the company’s full-scenario layout logic in the optical interconnect sector.

HashKey MENA (HashKey Middle East and North Africa) officially secured approval from the Dubai Virtual Assets Regulatory Authority (VARA) on July 17, 2026, expanding its regulated business scope to include virtual asset exchange-traded derivatives (VA ETD) services covering a range of perpetual contracts.

Crypto asset management firm CoinShares has launched a UCITS platform, debuting its first fund—the CoinShares Bitcoin Mining UCITS ETF—which began trading on Deutsche B?rse’s Xetra exchange on Tuesday. CoinShares stated that a key barrier preventing institutional investors from entering the crypto space has been product structure: many institutional investment mandates restrict holdings of debt securities, and the UCITS framework will effectively lift this limitation. The UCITS platform is a fund issuance and management platform based on the EU’s Undertakings for Collective Investment in Transferable Securities (UCITS) regulatory framework. It enforces strict requirements for fund products on investment limits, risk diversification, liquidity, and disclosure to safeguard investors, while offering the "European Passport" mechanism, enabling approved funds to be sold freely across the entire EU/European Economic Area (EEA). Crypto asset managers including CoinShares launching UCITS platforms essentially package Bitcoin mining and crypto-related strategies into compliant UCITS funds or ETFs, facilitating European institutional and retail investors’ safe allocation to crypto assets via traditional channels.

According to sources, BlackRock, Hillhouse Capital, and Temasek are set to serve as cornerstone investors in Auro Optoelectronics’ (Zhongji Chuangchuang) potential $8 billion Hong Kong IPO.
