Missing figures stay unavailable. Forward P/E requires a dated source. Annual revenue, revenue growth, net income and margin come from each company's own 10-K, in US dollars, and each row shows that fiscal year. Revenue growth compares the fiscal year with the prior year stated in the same 10-K. Net income is the full year amount attributable to the company, or available to common stockholders where the filing states only that, or consolidated net income. Each row names its basis. Trailing P/E reads "Not meaningful" when the dated trailing diluted EPS is a loss or zero. An operating margin appears only when the filing states both the operating income and the revenue for the same year.
Sources: SEC filings, Gloria daily closes and CoinGecko. Oldest record refresh: Oct 28, 2026, 5:41 PM EDT. Refresh is not a price or filing date. Each row shows its price date and its annual fiscal period. Peers use industry code and company size, or editorial selection. Market cap multiplies that row price by the company share total the latest SEC filing states for every share class together. Trailing P/E divides it by trailing diluted earnings from SEC filings. Rolled earnings per share are approximate because share counts can change between periods. Both appear only when the SEC data carries its date, so they are estimates at one price date, not synchronized filing valuations. Not investment advice.

Quoted token and share units can have different rights, multipliers and dividend treatment. This is not an executable premium or arbitrage signal.
Microsoft just made GPT-5.6 the default brain powering its entire 365 Copilot suite. The integration went live on July 9 across Word, Excel, PowerPoint, Copilot Chat, and Cowork, making this a day-zero deployment that matched the model’s general availability in ChatGPT and Codex.
What GPT-5.6 actually changes
The upgrade targets what OpenAI and Microsoft are calling “complex, multi-step tasks.” Think option comparisons in Excel, structured planning documents in Word, troubleshooting workflows, and data analysis that previously required a human to stitch together multiple steps.
Early feedback from users and enterprise experts has pointed to improved performance per token, which is a technical way of saying the model does more useful work for every unit of compute it consumes.
Here’s the thing about the rollout mechanics: Microsoft is using automatic task routing, meaning the system decides which model handles which request based on optimization criteria. Users can also manually select GPT-5.6 where a model picker is available, but the default behavior is algorithmic matching. Some enterprise users have already raised concerns about transparency, specifically around not always knowing which model is handling their request.

The partnership that keeps compounding
Microsoft and OpenAI’s partnership dates back to 2019, and this latest integration is a day-zero deployment in a productivity suite used by Fortune 500 companies. The phased rollout approach suggests Microsoft is watching performance telemetry carefully before pushing GPT-5.6 to every single Copilot interaction globally.
Why crypto and finance investors should care
This announcement contains zero mentions of crypto, blockchain, or digital assets. Microsoft and OpenAI kept the messaging squarely focused on productivity and enterprise tools.
Enterprise customers are already asking hard questions about data sovereignty, model transparency, and whether their proprietary information is being used to train future models. This deployment has already drawn transparency concerns specifically around the opaque model-routing system.
