Prediction markets have been easy to dismiss as a gambling product dressed up in financial language. That became harder to do when Intercontinental Exchange — the company that owns the New York Stock Exchange — quietly took a 25% stake in Polymarket. And when Robinhood partnered with Susquehanna to acquire a MIAX exchange platform that is already regulated and cleared specifically for prediction markets trading.

The finance industry has a long habit of showing up wherever money is moving and taking a cut. It is showing up here now. The question for investors is not whether prediction markets will become a legitimate financial product — Nick and Kasey think that trajectory is clear. The question is which publicly traded companies are best positioned to benefit, and how to think about the difference between a short-term hype cycle and a genuine secular growth theme.

In this episode, CSI steps outside its core semiconductor focus to cover the full prediction markets landscape and compare Robinhood and Interactive Brokers head-to-head on their Q1 2026 earnings — because the way those two businesses generate revenue tells you almost everything you need to know about which one is built for the long run.

Robinhood reported $1 billion in revenue, up 15% year over year, with EPS up just 3% — slower than investors expected. The stock dipped on the report. But the MIAX acquisition is genuinely interesting: a regulated, cleared prediction markets exchange that could morph from a retail gambling product into a professional risk management tool for investors hedging real portfolio exposure against real-world outcomes.

Interactive Brokers reported $1.68 billion in revenue, up 17% year over year, across 4.75 million accounts. The revenue chart tells a different story — smooth, consistent, institutional. Net interest income has grown to exceed transaction revenue over the past decade. ForecastEx, their prediction markets product, launched in 2024 and is already aimed at professional investors rather than retail gamblers.

The comparison matters. One business is built around hype cycles and transaction spikes. The other is built around compounding institutional trust. Both are in prediction markets now. Only one of them looks like Interactive Brokers fifteen years from now.
