Roblox (RBLX): Valuation Check as New Ad Business and Institutional Buying Signal Long-Term Growth Potential

Simply Wall St

Roblox (RBLX) just put its new advertising unit front and center, rolling out Rewarded Video ads that some on Wall Street think could reshape how the platform makes money over the next few years.

See our latest analysis for Roblox.

The new ad push lands as Roblox’s 1 year to date share price return of 61.81 percent and 1 year total shareholder return of 61.54 percent signal strong, but recently choppy, momentum around a 95.21 dollar share price.

If this kind of ad driven growth story interests you, it could be worth scanning other high growth tech names through high growth tech and AI stocks to see what else matches your risk appetite.

With bookings growing, a bold new ad business, and big name funds still buying, Roblox trades at a steep discount to Wall Street targets. Is this a mispriced growth engine, or is the market already discounting tomorrow’s gains?

Most Popular Narrative: 34.6% Undervalued

Against a last close of 95.21 dollars, the most followed narrative pegs Roblox’s fair value far higher, framing today’s pullback as a potential opportunity.

The evolving digital economy on Roblox, including expanded monetization opportunities like digital goods, Rewarded Video ads, and a systematized IP licensing marketplace, is expected to unlock new high margin revenue streams and enhance net margins as adoption matures.

Another View: Rich Multiples Raise the Bar

That bullish fair value sits awkwardly beside Roblox’s current price to sales of 15 times, versus 4.1 times for peers, an estimated fair ratio of just 5 times. If sentiment snaps back toward that fair ratio, how much multiple compression are optimistic buyers really prepared to stomach?
