Technical posts by the engineers writing the production code.
How prediction markets work, who the real traders are, what a bot actually does, and whether any of this can generate consistent returns.
Mirror profitable wallets - what works, what doesn't, and what survivorship bias actually costs you over a 12-month window.
The 2¢ trade gets harder on Polymarket alone. The cross-platform trade adds basis risk - and a much bigger envelope per fill.
100 req/min is generous until you're watching 50 markets. The priority-queue choreography that gets you through 200% load without throttle.

The honest answer, the ToS reading, the QCEX beta window, and why Kalshi is probably the right venue if you're US-resident.
The simplest prediction-market arb, walked through with a worked example, fees breakdown, and the leg-failure scenario nobody warns you about.
