Cursor in talks to raise $2B at a $50B valuation, driven by enterprise revenue surge

four-year-old AI coding tool Cursor is in advanced talks to raise more than $2 billion at a $50 billion valuation, according to TechCrunch. the round is led by returning investors Andreessen Horowitz and Thrive, with Nvidia also set to participate. it is reportedly already oversubscribed, nearly doubling the company's $29.3 billion valuation from six months ago.

the round is driven by enterprise adoption: Cursor is projecting roughly $6 billion in annualized revenue by end of 2026, up from $500 million in annualized revenue in December 2025. the deal, if it closes, would make Cursor one of the most valuable private software companies in the world without being an AI model developer.

The Build

tools, models, and dev releases

• OpenAI Codex desktop app gains computer use, an in-app browser, scheduled automations, and memory - beyond the plugin ecosystem, Codex can now operate macOS apps with its own cursor in the background and schedule "heartbeat" automations that run days or weeks later, positioning it as OpenAI's first move toward a general-purpose desktop agent (More)

• Anthropic releases Claude Opus 4.7 with a new xhigh effort level and 3.75MP vision - the model removes `temperature`, `top_p`, and `top_k` params in favor of discrete effort levels, signaling a shift toward effort-based rather than temperature-based steering for agentic workloads (More)

• Anthropic ships Claude Code desktop redesign with cloud-hosted Routines - Routines run scheduled agentic tasks - nightly triage, CI maintenance - on Anthropic's infrastructure rather than the developer's local machine, decoupling execution from an open laptop; available in research preview for Enterprise and API users (More)

• VS Code ships a standalone Agents companion app for parallel agentic workflows - the new app runs agent sessions across multiple repos simultaneously in isolated worktrees, with inline diffs, MCP server support, and direct PR creation; now in VS Code Insiders 1.116 (More)

• OpenAI Agents SDK v0.14 ships native sandbox execution - the update decouples orchestration from compute so agents can read/write files, execute code, and restore state via snapshots across providers including E2B, Modal, Cloudflare, and Vercel (More)

Founder Fuel

funding, acquisitions, and market moves

• Factory raises $150M at $1.5B valuation for AI coding agents in enterprise engineering - Khosla Ventures led the round with Sequoia, Insight Partners, and Blackstone participating; the company counts Morgan Stanley, Ernst & Young, and Palo Alto Networks as customers and differentiates on model-agnosticism, switching between Claude, DeepSeek, and others (More)

• Sequoia raises $7B expansion fund - nearly double its 2022 vehicle - co-stewards Alfred Lin and Pat Grady are directing the capital toward late-stage US and European AI bets including OpenAI, Anthropic, Physical Intelligence, and Factory, as both of Sequoia's flagship AI positions eye 2026 public listings (More)

• OpenAI acqui-hires personal finance startup Hiro - founder Ethan Bloch - who previously sold neobank Digit for ~$230M - announced the deal on April 13; the Hiro product shuts down April 20, marking OpenAI's second fintech acquisition in six months (More)

Longevity & Health

aging, biotech, and health research

• major Cochrane review concludes leading Alzheimer's amyloid drugs have "trivial" clinical benefit - pooling 17 trials and 20,342 participants including lecanemab and donanemab, the review found cognitive improvement over 18 months falls below the threshold for clinical meaningfulness; prominent researchers contested the methodology as conflating failed older drugs with newer approvals (More)

• saliva swab predicts mortality and frailty as accurately as a blood test, large study finds - a machine-learning model trained on 4,675 people identified 64 age-dependent bacteria in saliva and produced an aging score that predicted all-cause mortality, kidney decline, and cancer risk beyond conventional factors (More)

• calorie restriction lowers a key inflammatory protein in human fat tissue - without weight loss required - a Yale analysis of the CALERIE-II trial found that cutting calories by 14% over two years suppressed the complement protein C3a in visceral fat, opening a drug target that doesn't require dropping weight (More)

• oral longevity drug extends mouse lifespan by 33% and outperforms rapamycin in peer-reviewed study - the combinatorial compound mixes urolithin A, quercetin, nicotinamide riboside, alpha-lipoic acid, and a proprietary ingredient; it also reduced tumor incidence by 30%, though results are preclinical and human trials remain years away (More)

The World

regulation, policy, and geopolitics

• EU orders Google to share search ranking, query, and click data with rival engines and AI chatbots - the Commission's preliminary DMA findings would require Google to grant access on fair, reasonable, and non-discriminatory terms via an API; a binding decision is due by July 27, 2026, and Google publicly contested the measures as exceeding the DMA's mandate (More)

• EU threatens Meta with emergency order over WhatsApp AI access fees - a supplementary statement of objections issued April 15 alleges Meta charged third-party AI providers fees from October 2025 onward; the Commission could impose interim measures covering the entire EEA with fines up to 10% of global revenue (More)

• NATO and EU locked in "turf war" over control of Europe's €1 trillion rearmament budget - as European NATO members ramp toward a 5% GDP defense target, a structural conflict has emerged over the EU's "Buy European" industrial policy, which NATO - where Washington holds significant sway - opposes as complicating alliance procurement (More)
