Rush Street Interactive (RSI) is back in focus after reporting fourth quarter and full year 2025 results, with higher sales and net income, and issuing 2026 revenue guidance that signals management confidence in the business.

The latest earnings release and 2026 revenue guidance appear to have reinforced interest in Rush Street Interactive, with a 7 day share price return of 6.64% and 30 day share price return of 11.77%, while the 1 year total shareholder return of 69.38% and very large 3 year total shareholder return suggest momentum has been building over a longer window.

If these results have you looking beyond a single name, it could be a good moment to broaden your watchlist with our 19 top founder-led companies, a curated set of under the radar opportunities.

With RSI trading at $19.75 and sitting about 24% below one set of analyst targets and a similar gap to one intrinsic value estimate, you have to ask: is this a genuine mispricing, or is the market already accounting for that 2026 growth?

Most Popular Narrative: 19.6% Undervalued

With Rush Street Interactive closing at $19.75 versus a widely followed fair value estimate of $24.56, the current price sits well below that narrative anchor, putting extra weight on the assumptions behind that gap.

RSI's proprietary technology platform and product integration (e.g., seamless cross-play between poker, casino, and sportsbook) are driving higher user engagement, industry-leading ARPMAU, and improving gross and EBITDA margins as scale increases and third-party vendor costs are optimized.

Want to see what kind of revenue climb and margin shift need to hold for that fair value to stack up? The core of this story is multi year revenue compounding, a step up in profitability, and a future earnings multiple that leans heavily on that earnings path. Curious how those moving parts combine into a $24.56 number at an 8.18% discount rate, and what that implies for today’s price at $19.75? The full narrative lays out every assumption behind that call.

Result: Fair Value of $24.56 (UNDERVALUED)

However, you still have to weigh Latin American tax and regulatory shifts, as well as potentially higher marketing spend, which could pressure margins and weaken the 2026 upside story.

Another Angle On Valuation

So far you have a story that leans on future cash flows and fair value, but the current P/E of 60.7x tells a different story. That is far above the US Hospitality average of 23.4x, the peer average of 26.9x, and even the fair ratio of 32.1x. This points to meaningful valuation risk if expectations cool.

Numbers like that can be useful prompts to stress test your own assumptions, especially if you are weighing growth potential against the chance that the market simply recalibrates closer to that fair ratio. How comfortable are you with paying almost double that mark for RSI today?

Next Steps

If the mixed signals on value and growth have you thinking, now is a good time to look through the numbers yourself and decide how convincing the upside story really is. To see what the optimism is based on and weigh it against your own expectations, take a closer look at the 4 key rewards.
