Reuters, citing sources familiar with the matter, reports that the Trump administration is drafting a ban on imports of new Chinese data center components. The U.S. Federal Communications Commission (FCC) plans to impose import restrictions on Chinese optical transceivers—used for high-speed data transmission over data center fibers—and aims to announce and implement the measures within this year. The White House and FCC have not yet responded to requests for comment. Affected by this, according to market data from BIT (bit.com), pre-market trading in the U.S. optical communications sector has widened its gains, with: Pure Photonics ETF FOTO up 8.08%; Corning (GLW) up 8.10%; Marvell Technology (MRVL) up 7.64%; AAOI (Applied Optoelectronics) up 18.1% — the company manufactures high-speed optical modules (800G/1.6T) and focuses on AI data center transceivers; LITE (Lumentum Holdings) up 11.57% — a core supplier of optical communications lasers and optical modules, and a key player in AI data centers; COHR (Coherent Corp) up 14.01% — a leader in lasers, optical components, and photonics solutions, covering data center and industrial sectors; CIEN (Ciena Corporation) up 8.96% — which produces high-speed SerDes and connectivity chips, focusing on low-power interconnection for AI data centers.

Video game development giant EA will officially change ownership to the Saudi consortium.

According to a document from the European Commission, Saudi Arabia’s sovereign wealth fund Public Investment Fund (PIF) and a consortium of investors have secured EU approval under the bloc’s foreign subsidy rules to acquire global video game giant Electronic Arts (EA) for $55 billion. In another regulatory filing submitted last Thursday, EA confirmed it had obtained all required regulatory approvals by July 30 and expects the deal to close on August 4. In September 2025, EA announced it had reached a definitive agreement to be acquired by the consortium of PIF, Silver Lake, and Affinity Partners in an all-cash transaction valuing the company at roughly $55 billion. Turqi Alnowaiser, PIF’s vice president and head of international investments, stated that PIF holds a unique position in the global gaming and esports sectors and is committed to building and supporting ecosystems connecting players, developers, and IP creators. EA called the transaction the largest all-cash privatization acquisition in history. The buyers include Saudi Arabia’s PIF, U.S.-based Silver Lake, and Affinity Partners. Affinity Partners is an investment firm founded in 2021 by Jared Kushner, former U.S. President Donald Trump’s son-in-law, which has received substantial funding from Saudi Arabia; Silver Lake is a technology-focused investment firm. As such, the EA acquisition is almost entirely led by Saudi capital.

Analysts have disclosed a cluster of 28,555 Bitcoin wallets associated with the Qian Zhimin case, with a total value of approximately $1.8 billion.

On-chain investigator Specter disclosed that a wallet cluster holding approximately 28,555 Bitcoin (BTC, valued at ~$1.8 billion) has been identified, and it is possibly linked to the 60,000 BTC money laundering case involving Qian Zhimin. Weeks ago, a Bitcoin wallet dormant since 2017 suddenly transferred 1,020 BTC (worth ~$60 million) and began dispersing the funds across multiple addresses, exhibiting typical money laundering patterns. After tracing these transactions, analysts locked onto an on-chain wallet cluster connected to addresses previously tied to Qian Zhimin’s case by UK law enforcement. Qian Zhimin perpetrated large-scale investment fraud in China between 2014 and 2017, defrauding over 128,000 investors. UK authorities subsequently traced the flow of crime proceeds converted into Bitcoin, and the Metropolitan Police ultimately seized 60,000 BTC in the largest cryptocurrency seizure in UK history. In July 2021, UK authorities transferred the seized Bitcoin, creating identifiable on-chain address links. Based on on-chain evidence, analysts noted it is currently impossible to determine if these wallets remain controlled by the same actors, have been transferred to other custodians, or have already been identified by law enforcement.
