Beating AI News Flash : OpenAI has updated ChatGPT's ad-hoc chat functionality. Users can now choose to have ad-hoc chats read from existing memories, use custom commands and plugins, or save useful conversations directly to the history.

Temporary chats will not create new memories by default, nor will they appear in the chat list. They will only become regular chats after the user actively saves them.

According to BlockBeats, on August 28, the U.S. Securities and Exchange Commission (SEC) announced lawsuits against 38 entities, accusing them of making material misrepresentations in Form ADV filings submitted between 2025 and 2026, attempting to masquerade as legitimate U.S. investment advisory firms to gain the trust of retail investors and induce them to invest.

The SEC stated that these entities allegedly fabricated office addresses, provided invalid or unrelated phone numbers, and used highly similar ownership structures and financial data. Some entities also claimed that the private equity funds they managed had been audited by accounting firms, but the relevant accounting firms could not be found in the directories of U.S. federal or state public accounting agencies.

Furthermore, some entities displayed forged SEC registration certificates on their websites to create the illusion of being regulated. The SEC stated that some of these entities accessed the SEC filing system via IP addresses located outside of China and refused to provide relevant records to verify the authenticity of their filings. Currently, the ERA filings of the 38 entities involved have been removed from the SEC website. The SEC is accusing these entities of violating the Investment Advisers Act of 1940 and is seeking permanent injunctions, a ban on them continuing to file Form ADV as exempted reporting advisors, and civil penalties.

According to BlockBeats, on August 28th, Glassnode reported that Bitcoin's rapid rebound and renewed approaching $80,000 have led to more positive signals in the options market. Open interest (OI) in options contracts has risen in tandem with the BTC price, currently approaching 550,000 BTC, indicating a significant recovery in funding and participation in the derivatives market. Meanwhile, DVOL has rebounded sharply to around 41, suggesting a renewed demand for volatility, but it remains significantly lower than the previous high volatility range of 50-60, indicating that the market has not yet entered an extreme state.

From an option structure perspective, the 25 Delta Skew has narrowed significantly across all maturities, with the short-term Skew even turning negative. This indicates a decreasing demand for downside protection, and positions are gradually shifting towards a more balanced, or even upside-biased, direction. After breaking through $70,000, BTC has now entered a dense Gamma zone between $75,000 and $80,000, with long and short option exposures concentrated near key strike prices. As positions continue to adjust, this could further amplify the price's sensitivity to changes in the options market.

Recent options fund flows have been concentrated around $72,500 and $79,250, with significant buying of call options at both strike prices, while demand for put options has been relatively limited, indicating that traders are betting on further BTC gains. Overall, the BTC rebound has driven a continued recovery in options market positioning, reduced downside protection demand, and increased call option fund flows. While volatility has rebounded, it remains at a relatively moderate level. If the upward momentum continues, there is still room for further repricing in the options market.
