Good morning, builders. OpenAI's GPT-5.5 dropped this week with agentic capabilities and $5/M token pricing, while Anthropic quietly surpassed OpenAI with a $1 trillion valuation — and Meta is cutting 8,000 jobs to fund the AI arms race. Meanwhile, a $293M DeFi hack rattled institutional confidence and a U.S. soldier became the first person charged with insider trading on a prediction market.

🚀GPT-5.5 Launches With Agentic Coding While Anthropic Quietly Hits $1 Trillion

The Rundown: OpenAI released GPT-5.5 with advanced agentic capabilities and a 1M token context window, while Anthropic surpassed OpenAI in secondary-market valuation at $1 trillion driven by Claude Code adoption.

The details:

  • GPT-5.5 scores 82.7% on Terminal-Bench 2.0, is priced at $5/M input tokens, and is live now in ChatGPT and Codex with a 1 million token context window.
  • OpenAI Workspace Agents automate Slack and team workflows for free until May 6, 2026 across Business, Enterprise, Edu, and Teachers plans.
  • Anthropic surpassed OpenAI with a $1 trillion valuation on Forge Global, with shares scarce due to surging Claude Code adoption.
  • DeepSeek V4-Pro also launched this week with 1.6 trillion parameters, a 1M token context window, and confirmed compatibility with both Nvidia and Huawei chips — with the company seeking a $20B funding round backed by Tencent and Alibaba.
Why it matters: For founders and investors, this week crystallized the two-horse race at the frontier: OpenAI shipping fast with agentic tooling baked into enterprise workflows, and Anthropic commanding premium valuation on the back of developer adoption. The more urgent signal is DeepSeek's continued commoditization pressure — a 1.6T parameter open-weights model compatible with Huawei chips is a direct shot across the bow of U.S. AI export controls. Teams should be stress-testing whether their AI vendor lock-in is justified at current pricing, given how fast open-source alternatives are closing the gap.

🤖Meta Axes 8,000 Jobs and Cancels 6,000 Roles to Fund $135B AI Bet

The Rundown: Meta is cutting roughly 8,000 employees and canceling 6,000 open roles to redirect capital toward up to $135 billion in AI infrastructure spending this year.

The details:

  • Meta layoffs affect ~10% of staff (~8,000 jobs), with cuts going into effect May 20, while 6,000 open requisitions are being cancelled outright.
  • Google reports 75% of its own code is now AI-written, with its API seeing 60% token growth in Q1 2026 driven by agentic AI adoption.
  • Despite the AI investment wave, S&P 500 companies have reported only $300M in aggregate AI productivity gains — roughly what Anthropic earns every 1.5 days in token sales.
  • A 'tokenmaxxing' trend is emerging at Meta, Microsoft, and Salesforce, where employees wastefully burn AI tokens for internal leaderboard rankings, causing financial waste and system outages.
Why it matters: The Meta layoff is the most visible data point yet in a broader trade: human headcount for AI compute. For SaaS founders, this is both a threat and an opportunity. The threat is that enterprise buyers are using AI budget expansion as cover to slash software renewals — one case study showed a Claude integration replicating 95% of a vendor's features at 15% of the cost, driving a 45% renewal cut. The opportunity is that any tool helping companies actually measure and prove AI productivity ROI (the $300M vs. $135B gap is glaring) has a massive wedge to sell into.
