[Form 4] Rush Street Interactive, Inc. Insider Trading Activity

Rhea-AI Filing Summary

On July 3, 2025, Rush Street Interactive, Inc. (RSI) Chief Operating Officer Mattias Stetz filed a Form 4 detailing two open-market sales of Class A common stock executed under a pre-arranged Rule 10b5-1 trading plan dated August 16, 2024.

• July 1, 2025: 25,000 shares sold at a weighted-average price of $14.8058.
• July 3, 2025: 25,000 shares sold at $15.00.

After these transactions, Stetz directly owns 321,051 RSI shares and indirectly holds 205,448 shares through his spouse, for a combined beneficial ownership of 526,499 shares. The disposals reduce his direct holdings by roughly 13% while leaving a substantial equity position intact.

No derivative securities were exercised or disposed of, and the filing confirms that all sales were carried out under the 10b5-1 plan, mitigating concerns about opportunistic timing.

Positive

• Sales executed under a pre-arranged Rule 10b5-1 plan, reducing concerns about information-based trading.
• Officer retains 526,499 shares post-transaction, maintaining significant alignment with shareholders.

Negative

• 50,000 shares sold by the COO within two trading days, cutting direct ownership to 321,051 shares.
• Insider selling by a key executive may be interpreted as a bearish signal by some investors.

Insights

Securities Analyst

TL;DR: Neutral impact—planned sale of 50k shares; executive retains meaningful stake.

The two transactions total 50,000 shares at $14.81–$15, generating about $0.75 million. Because both trades were executed under a Rule 10b5-1 plan adopted on 16-Aug-2024, they appear pre-scheduled and unrelated to undisclosed information. Post-sale ownership of 526,499 shares keeps the COO’s interests aligned with investors. I consider the event routine and unlikely to affect RSI’s valuation or guidance.

Corporate Governance Expert

TL;DR: Governance-neutral; transparent 10b5-1 filing offsets perception risks of insider sale.

The Form 4 provides full price-range disclosure and cites the 10b5-1 plan, meeting best-practice standards. Although any senior-executive sale can attract scrutiny, the magnitude—50,000 shares over two sessions—does not threaten control and leaves the COO with over half-a-million shares. Accordingly, the transaction poses minimal governance or control risk.
