Rush Street Interactive’s stock took a sharp 10% tumble in after-hours trading on Tuesday after the online casino operator disclosed plans by senior executives to offload a significant chunk of their shareholdings, undercutting what had been a strong month for the company.

The timing caught some investors off guard. Just hours earlier, RSI had delivered upbeat FY 2026 guidance, projecting revenue growth of 31-36% year-on-year to hit $1.49-$1.54 billion. That’s the kind of double-digit EBITDA expansion that usually sends stock prices higher, not lower. The company had already climbed nearly 30% in the previous month and hit an all-time high on the day of the announcement.

Who’s Selling and How Much

The insider sales involve founder and executive chairman Neil Bluhm, CEO Richard Schwartz, and COO Mattias Stetz, who plan to collectively offload up to 10 million shares. Underwriters have a 30-day window to purchase an additional 1.5 million shares, potentially bringing the total supply to 11.5 million.

That’s a lot of stock hitting the market. Naturally, it sparked the selloff. But company leadership moved quickly to frame it as straightforward personal and estate planning rather than a loss of confidence in the business. Each executive is divesting less than 10% of their individual stakes, they emphasized.

The Reassurance Play

RSI isn’t sitting idle on the shareholder register either. The company is deploying its cash reserves to repurchase up to $30 million worth of stock tied directly to this offering. On top of that, the board has approved a broader $100 million buyback program, replacing the previous authorization.

Combined, that’s up to $130 million in potential repurchases, designed to absorb some of the new supply and support the stock price. Crucially, Bluhm and related entities will retain more than 40% ownership after the sale, keeping him as the largest shareholder. That’s a meaningful signal that the founder still has serious skin in the game.

Market Reading

Insider sales always trigger a bit of investor anxiety. But the context matters here. Strong guidance usually carries more weight than executive diversification, especially when the sellers are demonstrably staying heavily invested.

RSI’s own buyback commitment suggests management believes the stock remains attractively valued at current levels. Whether the market settles down after the dust clears will depend on broader market conditions and whether the company continues to execute on that growth guidance.
