Andy Bechtolsheim, the co-founder of Sun Microsystems and Arista Networks, has reached a settlement with the U.S. Securities and Exchange Commission on insider trading charges that will cost him close to $1 million and bars him from serving as a public company officer or director for five years.
The civil charges against Bechtolsheim, who has an estimated net worth of over $16 billion, is tied to Cisco’s acquisition of Acacia Communications in 2019. The SEC alleged on Tuesday that Bechtolsheim confidentially learned of an “impending acquisition” on July 8, 2019, and traded options of Acacia, netting him “combined illegal profits” of over $415,000 after the deal was made public the next day.
Cisco announced its agreement to buy networking company Acacia for $70 per share in a $2.6 billion deal, driving Acacia’s stock up 35%. The transaction ended up closing in 2021 at $115 per share for a total price of $4.5 billion.
The complaint, filed in federal district court in San Jose, California, alleged that Bechtolsheim, then chairman and chief development officer of Arista, learned that an acquisition of Acacia was fast approaching from an employee at a separate, unnamed multinational tech company. The employee had consulted with Bechtolsheim about a potential bid by that company to acquire Acacia, the suit said.
Immediately following the discussion, Bechtolsheim traded Acacia options in the brokerage accounts of a close relative as well as an associate, according to the lawsuit.
“Bechtolsheim knew or was reckless in not knowing that the information he learned about Acacia’s impending acquisition was material and nonpublic,” according to the complaint filed on Tuesday. “Bechtolsheim also knew or was reckless in not knowing that he had a duty of trust and confidence to keep such information confidential and not trade in Acacia securities based on this information.”
The SEC said Bechtolsheim settled its charges without admitting or denying the allegations against him. He agreed to pay a fine of $923,740.
Bechtolsheim, 68, resigned as Arista’s chairman and development chief in December but continues to serve as its chief architect. He’s the company’s biggest shareholder with a stake worth nearly $14 billion.
“While the SEC announcement did not involve any trading in Arista securities, Arista takes compliance to the company’s code of conduct and insider trading policy seriously,” an Arista spokesperson told CNBC in an email. “Arista will respond appropriately to the situation.”
Bechtolsheim’s attorneys didn’t immediately respond to a request for comment.
Bechtolsheim, who lives in Incline Village, Nevada, co-founded Arista in 2004 and took the company public a decade later. The networking vendor now has a market cap of close to $95 billion.
In 1982, Bechtolsheim co-founded Sun Microsystems with Scott McNealy, Vinod Khosla and Bill Joy, and served as chief hardware designer. Oracle announced its $7.4 billion acquisition of Sun in 2009.
Taiwan on Thursday announced an immediate one-year ban on the Chinese social media network Xiaohongshu, saying the app posed a risk of fraud.
Taiwan’s interior ministry said in a statement that it will block access to Xiaohongshu, also known in English as Rednote, calling it a potential “high-risk area for online shopping fraud.”
Authorities linked the platform to about 1,700 fraud cases that caused financial losses of over 247.7 million New Taiwan dollars ($7.9 million) since 2024, the ministry said. The app has over 3 million users on the island, the ministry said.
Officials also said that Taiwanese law enforcement agencies face “significant difficulties” obtaining necessary information because Taiwan lacks jurisdiction over the company.
The interior ministry said the app failed all 15 indicators in cybersecurity tests conducted by the National Security Bureau.
Taiwan’s internet service providers were instructed to block access to the app, Deputy Minister of the Interior Ma Shih-yuan said in a press conference Thursday.
The ministry also urged international platforms such as Google to “completely cease publishing Xiaohongshu advertisements.”
Authorities reminded the public not to download the app or stop using it if already installed.
In a Facebook post, Cheng Li-wun, chairwoman of the opposition Kuomintang party, said the move “significantly [restricts] Internet freedom,” and described the ban on Xiaohongshu as “a starting-point for building the Great Wall of the Internet,” by the ruling Democratic Progressive Party.
Xiaohongshu, Apple and Google did not immediately respond to CNBC’s request for comments.
In 2022, Taiwan banned Xiaohongshu from government devices, calling it a “united front” for Chinese propaganda.
Earlier this year, Taiwan sent a letter to Xiaohongshu’s parent company, Xingyin Information Technology (Shanghai), seeking “concrete improvement measures,” but the company did not reply.
Xiaohongshu is widely used in China and saw renewed interest in the U.S. earlier this year after a proposed ban on its competitor TikTok. That prompted TikTok users to flock to Xiaohongshu, adding roughly 700,000 new users to the platform, according to Reuters.

Shares of Moore Threads, a Beijing-based graphics processing unit (GPU) manufacturer often referred to as “China’s Nvidia,” soared by more than 400% on its debut in Shanghai following its $1.1 billion listing.
Moore Threads’ IPO was led by CITIC Securities, which served as the lead underwriter for the offering. The joint book runners on the deal were BOC International Securities, China Merchants Securities, and GF Securities.
The company, which is not yet profitable, said in its listing that the IPO proceeds are needed to accelerate several core research and development initiatives, including new-generation self-developed AI training and inference GPU chips. A portion of the funds will also be used to supplement working capital.
Moore Thread’s successful IPO comes despite it being placed under U.S. sanctions in 2023, which limited its access to advanced chip manufacturing processes and foundries.
The firm is representative of a growing cast of Chinese companies developing AI processors amid Beijing’s efforts to reduce reliance on American chip designer Nvidia.
Other companies in the space include tech giants like Huawei, as well as more specialized players like Cambricon — a firm whose shares on the Shanghai exchange have surged more than 100% year to date.
Washington has maintained varying export restrictions on Nvidia for years, preventing it from selling its most advanced AI chips to China. More recently, Beijing has also stepped in to block imports of Nvidia’s chips as it tries to encourage domestic alternatives like Moore Threads.
Newer players like Enflame Technology and Biren Technology have also entered the space, aiming to capture a share of the billions in GPU demand no longer served by Nvidia. Chinese regulators have also been clearing more semiconductor IPOs in their drive for greater AI independence.

SoFi shares fell almost 6% in extended trading Thursday after the fintech company announced a $1.5 billion stock offering.
The company, which provides online loans and other banking services, said in a press release that it will use the proceeds for “general corporate purposes, including but not limited to enhancing capital position, increasing optionality and enabling further efficiency of capital management, and funding incremental growth and business opportunities.”
The announced offering comes after SoFi’s market cap almost doubled so far in 2025. The stock price is up more than sixfold since the end of 2022.
A company’s share price often drops on a planned share sale as the offering dilutes the value of existing holders’ stakes.
In its third-quarter earnings release in late October, SoFi reported revenue growth of 38% from a year earlier to $961.6 million, while net income more than doubled to $139.4 million. The company reported cash and equivalents of $3.25 billion.
