Mercury nears $5B valuation 🚀, Payment rails for AI agents 🤖, Bolt fires 1/3 sta

**TL;DR** - Mercury Bank closes on $5B valuation; emerging payment rails infrastructure purpose-built for AI agents.

The 10-Second Pitch

• Mercury valuation jump reflects business banking market opportunity for tech-native companies
• Agent-native payment rails (programmable, API-first, sub-second settlement) now a funded category
• Bolt second act involves AI agent payment delegation - letting agents pay on behalf of users with limits

Setup in 3 Steps

1. If building agentic payment workflows, Mercury API most developer-friendly option right now

2. Design agent payment primitives around idempotency - agents retry, and retries must be safe

3. Evaluate whether your current payment stack handles agent-initiated sub-minute settlements

**Example Prompt:**

Design a payment authorization system for an AI agent that makes purchases up to $50 without user confirmation.

Verdict

AI agent payment infrastructure race underfunded relative to the problem. Watch this space.
