Microsoft's MAI-Thinking-1 — a sparse mixture-of-experts model with 35 billion active parameters out of roughly one trillion total — scores 97.0% on AIME 2025 and 94.5% on AIME 2026, trained on commercially licensed data with no OpenAI distillation, and was preferred over Claude Sonnet 4.6 by independent raters at Surge. The model enters private preview on Microsoft Foundry, giving enterprise developers on Azure a non-OpenAI reasoning option — a concrete sign that Microsoft is building its own frontier AI capability rather than reselling OpenAI's.

Cloudflare is acquiring VoidZero, the startup behind Vite (~129M weekly downloads), Vitest, Rolldown, and Oxc, with the existing team staying on and all projects remaining MIT-licensed and community-driven. Cloudflare is committing $1M to a Vite ecosystem fund administered by the Vite core team — a structural backstop for the neutrality that earned Vite its position as the shared foundation under Vue, SvelteKit, Nuxt, Angular, and a dozen other frameworks.

{"title": "AI-attributed U.S. job cuts surged from 7% in January to 40% in May", "summary": "Challenger Gray reports 97,006 U.S. job cuts in May — AI cited in 38,579 of them, the highest monthly AI-attributed total since Challenger began tracking the category in 2023, with the share rising from 7% in January to 40% in five months. Tech leads with 123,653 cuts through May (+66% vs. 2025) while simultaneously topping hiring announcements, a pattern consistent with structural headcount reallocation to AI infrastructure rather than sector contraction."}

Uber burned its entire 2026 AI budget in four months — after ranking staff by usage and urging maximum consumption — and now caps agentic coding tools at $1,500 per employee per month, with overages requiring explicit approval. The COO's admission that drawing a line between AI spend and new consumer features is hard marks a notable inflection: one of the world's most AI-forward enterprises is publicly questioning the ROI of agentic coding tools at scale.

MHI and Preferred Networks signed a business alliance on June 2 to jointly develop AI for defense and social infrastructure, pairing MHI's hardware and system integration with PFN's PLaMo foundation models and MN-Core processors — with a capital tie-up targeted inside FY2026. The alliance is an explicit response to Japan's concern over foreign AI supply-chain dependence, marking the formation of a domestic AI stack inside Japan's defense-industrial sector.

TSMC CEO C.C. Wei told shareholders on June 4 that demand at leading nodes will outpace capacity by 25–30% in 2026, with CoWoS advanced packaging — which stacks HBM memory on Nvidia and custom-silicon accelerators — sold out and the constraint not lifting until at least 2027. With Alphabet committing $84.75B in new AI data-center equity and other hyperscalers accelerating their 2026–2027 capex, the TSMC bottleneck is now a hard ceiling on how fast AI infrastructure can scale — demand is there, the silicon isn't.

Benchmark closed $2B across two funds — a $1.25B growth vehicle and a $750M early-stage fund — ending the ~$425M small-fund discipline that defined the firm since the 1990s, with the pivot funded by a $3.25B return from the Cerebras IPO. The last high-prestige holdout to early-only investing has moved, a concrete marker that AI infrastructure round sizes are now too large for any major firm to sidestep without missing the cycle.

Ramp closed a $750M Series F at $44B — up from $13B in March 2025 — led by ICONIQ, GIC, and Ontario Teachers' Pension Plan, with run-rate revenue now exceeding $1.5B and the company at positive free cash flow. The AI token spend management angle is new territory: with Brex absorbed by Capital One and Rippling bundling HR alongside spend, Ramp is positioning as the standalone platform for companies trying to control rising AI service costs.

Uber has channeled close to $500M into Nuro — a $203M Series E plus milestone-linked tranches — to deploy 35,000 driverless vehicles built on Lucid Gravity SUVs with Nvidia DRIVE AGX Thor, routed through Uber's ride-hailing network before end of 2026. Nuro has already cleared its first milestone and holds California DMV approval for driverless testing, a sign that robotaxi buildouts are consolidating into multi-partner capital-plus-hardware-plus-platform stacks rather than single-company end-to-end plays.
