first_img OpenAI is facing a class-action lawsuit, accused of allowing outsourced personnel to read ChatGPT conversations

Two ChatGPT users from California filed a proposed class action lawsuit against OpenAI in the United States District Court for the Northern District of California this month, accusing the company of failing to adequately inform users that their real conversations were being handed over to external contractors for processing. The lawsuit was served to OpenAI on September 2, focusing on its internal initiative Project Lily. According to the complaint, "AI data reviewers" and "chatbot evaluators" recruited through a third-party staffing company read real ChatGPT prompts and complete conversations, summarize user intent, and score and comment on responses from four models on a scale of 1 to 7.This process is known in the industry as reinforcement learning from human feedback (RLHF), which is a fundamental method for enhancing chatbot capabilities. The complaint states that users were never explicitly informed that a person, rather than a machine, might be reading their conversations. OpenAI filters conversations through an automated system before human review, but the complaint alleges that the filters cannot intercept all content, and personal details sometimes still reach contractors. 404 Media first reported on the project on September 14 and found that the reviewers' dashboard included "user memory summaries," which could expose users' approximate locations, occupations, or private life information, even though usernames had been removed.OpenAI stated that such reviews aim to reduce two behaviors: chatbots behaving too much like humans and overly catering to users, referred to by researchers as "flattery." The complaint raises eight legal claims, including violations of California's Unfair Competition Law, Consumer Privacy Act, and common law claims for intrusion into private affairs, with the plaintiffs seeking damages, restitution of unjust enrichment, and punitive damages.

first_img ARK partners with Securitize to tokenize venture capital funds, holdings include OpenAI and Anthropic

According to CoinDesk, asset management company ARK Invest announced a partnership with tokenization platform Securitize to tokenize its ARK Venture Fund (ARKVX), initially issuing it on Ethereum, with potential expansion to other blockchains in the future. The fund invests in private and public companies, with holdings including OpenAI, Anthropic, Stripe, and Databricks. ARK founder and CEO Cathie Wood stated that bringing the ARK Venture Fund on-chain is a natural extension of its mission to democratize investment in disruptive innovation.Securitize CEO Carlos Domingo stated that this move provides investors with diversified exposure to popular private tech companies, allowing them to hold both OpenAI and Anthropic simultaneously if they are uncertain about which will win the AI race. He also noted that tokenization does not put these companies or their shares on-chain; instead, investors receive an on-chain representation of the fund's equity, while the underlying assets remain private, but user investments are liquid. Securitize also plans to provide daily net asset values and support on-chain market trading of fund equity.This collaboration builds on the existing relationship between the two parties, as ARK made a strategic investment in Securitize last year. Currently, Wall Street asset management companies are accelerating the introduction of traditional financial products to the blockchain, with early attempts like BlackRock's BUIDL and Franklin Templeton's BENJI fund primarily focused on U.S. Treasury and money market products, now expanding into stocks and private markets.

PitchBook provided a valuation scenario for Kalshi, with a maximum of 42.1 billion USD

According to a 46-page report from financial investment data company PitchBook, the market platform Kalshi has a baseline scenario valuation of approximately $30.4 billion, a peak valuation of about $42.1 billion during strong market performance, and a pessimistic scenario of $22.8 billion. Kalshi completed a $1 billion Series F financing in May this year, with a post-money valuation of $22 billion.PitchBook expects Kalshi's revenue to reach $6.4 billion by 2030, with adjusted profits reaching $3.7 billion, and believes that partnerships with platforms and market makers such as Robinhood and Susquehanna will help consolidate market share. The report lists the regulatory risks of the sports prediction market as a key variable affecting valuation, with data showing that the sports market currently contributes about 69.9% of Kalshi's event fee revenue; if Exotics products such as multi-event combinations are included, the proportion rises to 82.4%.Several states in the U.S. and Native American tribes are suing over the legality of Kalshi's sports prediction products, and related cases have created discrepancies between federal appellate courts, with the Supreme Court expected to intervene next year. PitchBook believes that even if the final ruling is unfavorable to Kalshi, the company may still adjust its business model through state-level licensing and the development of non-sports prediction products, but a significant decline in sports revenue will still notably impact its growth expectations.

first_img Australian Prime Minister: OpenAI AI entity first invaded government website

Australian Prime Minister Anthony Albanese stated to reporters in New York on Wednesday that an AI entity built by OpenAI breached the Australian government website Medicare Statistics Reporting Service portal in June this year, accessing both public and non-public documents without authorization. The portal is managed by Services Australia and stores non-sensitive information such as Medicare expenditure data. This appears to be the first known incident of an AI entity breaching a government website.Albanese indicated that it is currently believed that no personal information was accessed, but the Australian Signals Directorate is assisting in a forensic investigation to determine which other government systems may have been affected. He mentioned that he has directly raised the matter with OpenAI CEO Sam Altman and expressed disappointment that the company took about three months to inform the government, deeming the manner of notification equally unacceptable.In a statement provided to Australian ABC News, OpenAI stated that it is reviewing the model behavior deviations that occurred during training and evaluation, and identified that its model engaged in activities involving multiple Australian government websites when querying relevant answers and statistics about Australia in internal evaluations, and that the model "took actions that we did not intend."

first_img OpenAI opens the Daybreak cybersecurity tool to the Ukrainian government

OpenAI announced that it is opening its AI vulnerability detection tool Daybreak to Ukraine's Ministry of Digital Transformation to locate and fix software vulnerabilities before they are discovered by Russian hackers. The news was announced on Wednesday during the United Nations General Assembly by Dmytro Kushneruk, Ukraine's Consul General in San Francisco, and Sasha Baker, OpenAI's National Security Policy Lead.Daybreak is based on OpenAI's flagship large model GPT-5.6 Sol and can scan outdated systems for weaknesses, verify whether suspected vulnerabilities can be exploited, and confirm whether patches actually close the vulnerabilities before they are released. OpenAI has previously opened the model to cybersecurity agencies in France, Germany, and Poland, where Poland's CERT Polska discovered six vulnerabilities in commercial router software, all of which have been fixed by the vendors.Ukraine's CERT-UA handled nearly 6,000 cyberattacks in 2025, a 37% increase from 2024, with local governments and government agencies being the hardest hit. This opening follows OpenAI's commitment to a $1 billion subsidy program announced on September 3, which is said to expand to "partner countries" in the coming weeks. Jamie MacColl, a researcher at the Royal United Services Institute, told the BBC that Western companies can also gain valuable intelligence from active conflict zones.
