According to Bloomberg, the Central Bank of Ireland has fined Coinbase's Irish subsidiary €3.25 million (approximately $3.6 million) due to deficiencies in its outsourcing governance framework and inadequate customer fund protection measures.Regulators pointed out that the company relied too heavily on the U.S. Coinbase Group to execute customer fund protection processes, and design flaws in the system along with insufficient control testing led to a long-term shortfall in the designated customer fund protection accounts.A Coinbase spokesperson stated that the relevant issues mainly occurred during the U.S. banking crisis in 2023, when the company directed customers to deposit funds into other bank accounts of Coinbase to mitigate potential losses from bank failures. However, this practice resulted in the mixing of customer funds with those held by other entities of Coinbase, which did not comply with regulatory requirements.Last year, the Central Bank of Ireland also fined Coinbase Europe €21.5 million for violating anti-money laundering and counter-terrorism financing transaction monitoring obligations (which included a 30% settlement discount).

According to Ramp's tracking of payment data from over 70,000 U.S. companies, approximately 80% of Anthropic and OpenAI's enterprise revenue comes from the top 1% of clients. In August and September, enterprise Token spending saw nearly zero growth for two consecutive months; although it reached a historical high at the beginning of October, it was only 1.5% higher than the peak in August.According to Ornn data, the actual Token price index for Anthropic fell from over $1.70 in mid-September to $0.83, a decline of more than 50%, while OpenAI's corresponding index was $0.45. According to YipitData, the top 1% of Anthropic's clients contributed 46% of revenue in August, up from 25% a year ago. Ramp data shows that the paid adoption rate for enterprise AI in September only increased by 0.62 percentage points to 55.9%. Ramp's chief economist Ara Kharazian believes that growth is shifting from expanding the paid user base to enhancing the depth of use among existing users.Goldman Sachs warns that the growth rate of Token demand must exceed the decline in prices to support sustained investment in computing power.

Goldman Sachs data also shows that the realized return on invested capital for Amazon, Alphabet, Meta, Microsoft, and Oracle has dropped from 40% to 25%, the lowest since 2016.
