Insights

Equity ownership and insider-trading analyst

Routine pre-planned insider sale with sizable holdings retained.

The Chief Operating Officer of Rush Street Interactive, Mattias Stetz, sold 20,000 Class A shares at a weighted average price of $17.6693 on February 2, 2026. The transaction is explicitly described as occurring under a Rule 10b5-1 trading plan, indicating it was pre-arranged rather than opportunistic.

Following the sale, Stetz still holds 289,624 shares directly and an additional 165,448 shares indirectly through his spouse, so his reported economic exposure remains substantial. The price range of $17.18 to $18.13 simply reflects multiple executions within that band and does not itself signal a particular view beyond the disclosed plan.

Overall, this looks like a routine diversification or liquidity event rather than a transformative change in insider ownership. Future company filings may provide additional context if his ownership position changes materially.
