Rush Street Interactive, Inc. (RSI) Stock Price & How to Invest

Rush Street Interactive, Inc. (NYSE: RSI) runs real-money online casino games and sports betting through its own technology platform in regulated markets across the United States, Canada and Latin America. Its consumer brands include BetRivers, PlaySugarHouse and RushBet, and it is live in roughly fifteen US states plus Ontario, Colombia, Mexico and Peru, with an Alberta launch expected in mid-2026. Unlike the two market leaders, RSI leans heavily on higher-margin online casino (iGaming) rather than pure sports betting, and it has built a differentiated position in Latin America.

The investment picture is a profitable growth story that has re-rated sharply. RSI reported record Q1 2026 revenue of about $370 million (up roughly 41% year over year), record net income of about $26 million, and adjusted EBITDA up about 81%, then raised full-year 2026 guidance. The stock has roughly doubled over the past year and now trades at a high multiple of earnings, so the story is less about whether the business works (it does) and more about whether growth, margins and geographic expansion justify a valuation that already prices in continued execution.

RSI competes against far larger and better-capitalized rivals including FanDuel (Flutter), DraftKings and BetMGM, which can outspend it on marketing and product. State and international gaming taxes can rise unexpectedly (for example a temporary emergency 16% tax decree in Colombia), directly compressing margins. Regulatory change, including new markets opening slowly or existing ones tightening rules, drives much of the growth story and is outside the company's control. The emergence of prediction markets and sweepstakes-style operators adds a new competitive and regulatory wildcard. Finally, the stock trades at a high multiple, so any slowdown in revenue growth or user additions could trigger an outsized share-price decline.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Rush Street Interactive, Inc.'s investor relations page or your broker.

• Revenue (TTM): ~$1.3B
• FY2026 revenue guidance: ~$1.49B to $1.54B
• Q1 2026 revenue (YoY): ~$370M (+41%)
• FY2026 adj. EBITDA guidance: ~$230M to $250M
• Market cap: ~$7B to $7.5B
• P/E (trailing): ~45x to 90x (varies by source)

RSI has moved from a cash-burning growth story to a profitable one, with record Q1 2026 revenue and net income and raised full-year guidance. The valuation is elevated, with a price-to-sales ratio near 5 and a trailing P/E reported anywhere from the mid-40s to roughly 90 depending on the source, so much of the near-term growth appears already reflected in the price.

There are three common ways to get RSI exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so RSI sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where RSI fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

RSI is a genuinely profitable, fast-growing niche operator in online gambling, but its rich multiple leaves little room for the growth and margins to disappoint.

Whether RSI is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is RSI a buy?, and where the stock could go from here in the RSI stock forecast.
