A broke 23-year-old just made $500,000 with an agentic loop that was too expensive to run a month ago. Then Claude Sonnet 5 came out, and the cost fell off a cliff. He'd built the bot last year, in Lisbon, and killed it after a month. The API bills ate everything it made. When Sonnet 5 launched he turned it back on. Same bot, a tiny fraction of the cost. This bot wallet: polymarket.com/@0xb55fa1296e… Anthropic says it runs on its own at a level that used to take their biggest, priciest models. Running a bot all day used to cost a fortune. Now it barely costs anything. Here's why the cost was the whole problem. A real trading bot isn't one question to an AI. It's a loop that runs all day. It makes a trade, sees how it went, learns from it, and adjusts. Then it does it again, thousands of times. Every step costs money. On the old models, running that loop nonstop drained your account before it ever figured anything out. Sonnet 5 runs the same loop for pennies on the dollar. So now it can run forever, and the longer it runs the better it gets. It keeps what works, drops what doesn't, and rewrites its own rules every night. Last month that loop cost him about $4000 a day. Now it's under $4. That gap is the difference between "not worth it" and $500,000. Sonnet 5 isn't just smarter. It made running a real loop cheap, and that's what put it in reach of regular people. Save this - it's the post you'll wish you'd read before everyone piles in.
