The new Claude Opus model is legit insane. This weekend I met a 16yr old making $600k a month with a vibe-coded prediction market arbitrage bot he started in early November. I asked how he built it so fast. He said he wrote a design doc in Claude Opus 4.5, dropped it into Cursor with Sonnet 4.5, and it worked on the first try. His goal is to get to $2M a month this year. Running everything under his mom's Polymarket and Kalshi accounts. A bug in his resolution logic cost him ~$400k on Christmas (!!!). He fixed the entire engine during dinner and was back to printing by midnight. And right now is still the worst these tools are ever going to be.(intern)
