On Roblox, players spent $6.8 billion in 2025.

Roblox has been around since 2006. Players buy Robux to dress up, unlock items or move faster in games. In 2025 they spent $6.8 billion, almost ten times more than in 2019. On the stock market, the company is worth $35.7 billion (Nov 13, 2026).

Of that money, $1.5 billion went to game creators.

In 2025, Roblox paid $1.5 billion to studios and creators, 13 times more than in 2019. Over 23,500 creators got paid. But the money is very unevenly spread: the median creator makes about $1,500 a year, while the top 10 average $65.7 million.

And soon, anyone can make a game.

The computing power of the biggest AIs grows 5 times every year. On Roblox, typing one sentence already makes a playable game: with Build, over 70,000 games were published in one quarter.

The real problem: being seen.

7 million games are played every day. Yet only 50 games take half of all the hours played. A good game nobody sees earns nothing.

Roblox ads exist for this.

In Ads Manager, you set a budget and Roblox puts your game on the home page and in search. Over 70% of the 100 top-earning games run ads. The costs below are platform averages as of Nov 11, 2025: a ballpark, not a promise.

What a Robux is worth, from player to studio.

A player pays about $10 for 1,000 Robux. If they spend them in your game, you get 700. At the $0.0038 DevEx rate, that's $2.66 in your account. Cash-out starts at 30,000 Robux earned, i.e. $114.

  3. You cash out

So the question isn't “is my game good”. It's “how much does a player I pay to bring in earn me”. That's what we measure.

Questions

Why is it free?

We're learning to measure what a new player is worth. Your numbers help us build the method. We only keep aggregated numbers.

Do you touch my Robux or my account?

No. We pay for the ads with our card. You only give us the right to create campaigns in your group, and you can remove it whenever you want.

Will you publish my results?

Only with your written OK. Otherwise the report stays between us.
