OpenAI 28-Day Sprint Day 5: Build Polkadot (DOT) on Mobile, Codex Predicts Next Instruction

After expanding its stock repurchase authorization to $235 billion, NVIDIA has begun emphasizing returning cash to shareholders using free cash flow (FCF) net of "strategic uses"—meaning external equity investments will also eat into cash available for buybacks and dividends. However, NVIDIA has not formally revised its traditional FCF calculation formula. Data shows that in the first half of its fiscal year ending July 26, NVIDIA posted a net cash outflow of $35.2 billion from equity investments, plus an additional $4.5 billion in cash withholding taxes related to employee stock vesting, and roughly $9 billion in buybacks used to offset share dilution from equity incentives. If these expenses are factored in, its FCF would drop from the official figure of $69.9 billion to around $21.7 billion, a reduction of roughly 69%. Over the same period, NVIDIA added $24.9 billion in long-term debt, which partially funded additional stock repurchases. While Wall Street projects its fiscal 2028 FCF will exceed $330 billion, if strategic investments continue to expand, the actual cash available for shareholder returns could be significantly lower than what the traditional metric suggests. NVIDIA’s investments in AI firms like OpenAI and Anthropic also create a circular flow of funds with its chip sales, sparking market concerns about the sustainability of the AI investment boom.

According to Lookonchain’s monitoring, three wallets likely belonging to the same crypto whale transferred 2,903 ETH to Coinbase after remaining dormant for over 9 years. Valued at current prices, the transfer is worth approximately $7.22 million. Data shows that when these wallets received the ETH nine years ago, ETH was priced at just $9.9. The asset now holds an unrealized profit of around $7.19 million, with a return on investment (ROI) of roughly 250 times.

Beating AI Express News, according to a Bloomberg report, OpenAI and Anthropic have significant differences in their revenue accounting standards, making the annualized revenue figures released by the two AI giants difficult to compare directly, and intensifying investors’ concerns about the growth prospects of the AI industry. The report notes that Anthropic includes total sales generated through cloud service partners such as Amazon in its revenue, while OpenAI only recognizes the net revenue share it receives from partners like Microsoft. Since neither company has published standardized financial statements, investors currently struggle to accurately assess their actual business scales. Annualized revenue (ARR) also has limitations. Sources familiar with the matter revealed that OpenAI expects its full-year 2026 actual revenue to be around $35 billion, roughly half of its annualized revenue target of $700 billion by the end of the year. Meanwhile, documents reviewed by Bloomberg show that Anthropic’s actual 2025 revenue was approximately $4.6 billion, while its then-reported annualized revenue exceeded $9 billion. Analysts point out that annualized revenue is typically extrapolated from short-term performance or contract values, and cannot be equated to actual full-year recognized revenue. Against the backdrop of high valuations for AI giants and tech stocks trading at elevated levels, uncertainties surrounding revenue growth rates and accounting standards may further impact the market’s judgment of AI investment returns.
