AI News of the Week: Microsoft Polaris, Anthropic's $965B, and SoftBank's Mega Investment
Welcome to the AI News Update from CribConnects AI. Every morning we bring together the most important AI developments for leaders and professionals making strategic decisions. These are the five biggest stories of this week (May 26 - June 2, 2026).
1. Microsoft launches Project Polaris at Build 2026
On June 2, Microsoft opened its Build 2026 developer event in San Francisco by announcing Project Polaris: its own mixture-of-experts coding model that will replace GPT-4 Turbo as the default engine for GitHub Copilot. According to Microsoft, Polaris scores at or above Claude 3.7 Sonnet on the SWE-bench Verified benchmark, at considerably lower inference costs. Starting in August 2026, Copilot subscribers will be migrated automatically, with an optional 3-month fallback period on GPT-4.
What this means: Microsoft is cutting its OpenAI dependency for Copilot once and for all. For enterprise customers running on Copilot, this means lower costs and more tightly integrated Azure infrastructure, but also a new vendor lock-in to assess deliberately.
2. Anthropic raises $65 billion at a $965 billion valuation
Anthropic closed a $65 billion funding round this week at a valuation of $965 billion. That puts the company ahead of OpenAI for the first time, which was valued at $852 billion in March. At the same time, Anthropic filed confidential S-1 paperwork with the SEC for a possible IPO, ahead of OpenAI's.
What this means: The AI model market is turning from a one-horse race into a genuine duopoly at the top, with serious competition on both model performance and enterprise distribution. A good moment for procurement teams to renegotiate commercial terms.
3. SoftBank invests €75 billion in French AI data centers
At the 2026 Choose France summit, SoftBank announced it will invest up to €75 billion ($87.5 billion) in developing 5 gigawatts of AI data center capacity in France. The first phase consists of €45 billion for 3.1 GW of capacity in the Hauts-de-France region, to be delivered in 2031. This is the largest AI infrastructure investment ever announced in Europe.
What this means: European organizations are getting serious in-region compute capacity, which makes GDPR and NIS2 compliance projects considerably simpler. European AI sovereignty is moving from policy paper to physical infrastructure.
4. GitHub Copilot switches to token-based billing
As of June 1, 2026, GitHub Copilot has moved from a flat subscription model to token-based billing. Usage is now charged per request, similar to direct API pricing. For light users it stays cheaper; teams working intensively with agentic Copilot will see their cost per developer go up.
What this means: Time to actively monitor Copilot spending and set up internal governance, much like cloud cost management. If you don't have a FinOps practice for AI, you'll feel it this quarter.
5. Nvidia announces RTX Spark and Vera Rubin at Computex
CEO Jensen Huang opened Computex Taipei on June 1 with the message that "AI is now a profit generator". Nvidia unveiled a new RTX Spark processor for Windows laptops and announced expanded production of the Vera Rubin AI platform. The message to Wall Street: AI is no longer a capex topic, but a measured return category.
What this means: Local AI workloads on laptops are becoming genuinely feasible for enterprise scenarios with sensitive data. For IT strategy: revisit your 2027 hardware refresh plan.
What does this mean for your organization?
This week marks a shift: AI infrastructure, model competition, and commercial models are all maturing at the same time. The question for leaders is no longer whether AI should be deployed strategically, but how to align vendor choices, cost structure, and governance with that maturity.
At CribConnects AI, we help organizations translate developments like these into concrete roadmaps. Want to talk through what this week means for your context? Get in touch via [email protected].
