Is RSI a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for Rush Street Interactive (RSI) rests on iGaming mix and margin expansion: RSI generates a large share of revenue from online casino, which carries structurally higher margins than sports betting. Revenue (TTM) is ~$1.3B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: RSI competes against far larger and better-capitalized rivals including FanDuel (Flutter), DraftKings and BetMGM, which can outspend it on marketing and product. Whether RSI is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
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.
What's the case for buying RSI?
1. iGaming mix and margin expansion
RSI generates a large share of revenue from online casino, which carries structurally higher margins than sports betting. As more US states legalize iGaming and existing players deepen engagement, this mix supports the rapid EBITDA growth (2026 adjusted EBITDA guidance of roughly $230 to $250 million, up 50% or more year over year).
2. Latin America and international expansion
Markets such as Colombia, Mexico and Peru are growing faster than North America, with Latin American monthly active users up more than 50% year over year in Q1 2026. New launches like Alberta, Canada add regulated jurisdictions. This geographic diversification is a differentiator versus US-only peers.
3. Improving profitability and cash generation
After years of losses common to the sector, RSI is now consistently profitable and generating cash, which reduces reliance on external funding. Rising monthly active users (about 839,000 in Q1 2026) combined with disciplined marketing spend has flipped the model from cash-burning to self-funding.
4. Scarcity value as an acquisition candidate
As a smaller, profitable, tech-owned operator, RSI is periodically viewed as a consolidation target in a maturing industry dominated by a few giants. Any strategic interest could support the valuation, though it is speculative and not a reason on its own to own the shares.
What are the risks to RSI?
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.

How do you decide if RSI is a buy?
Rather than asking whether RSI is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold RSI indirectly through an index or sector ETF before adding more.
