I still remember when Sea of Thieves finally showed up on Steam after years of being tied to the Microsoft Store on PC. My first thought was pretty simple: do I finally get a free Steam copy if I already own the game somewhere else? The short answer was no, and the longer answer is still worth knowing in 2026, because it explains how cross-play and cross-progression actually work in Sea of Thieves.

🏴‍☠️ Do Existing Owners Get a Free Steam Copy?

No, and Rare made that very clear in its FAQ. It does not matter whether you bought Sea of Thieves on Xbox One, Xbox Series X|S, or through the Microsoft Store. You will not be handed a Steam key for being a loyal pirate. I totally understand why people asked, because having a unified library is nice, but buying a game on one storefront does not automatically unlock it on another.

There was another limitation worth knowing. Steam does not support Xbox Game Pass for PC, so Game Pass subscribers could not simply grab the Steam version through their subscription. Instead, they had to stick with the Xbox app. That is still a pretty common source of confusion for new players.

Question Answer
Do Xbox or Microsoft Store owners get a free Steam key? No
Does Steam support Xbox Game Pass for PC? No, Game Pass players use the Xbox app
Do I need an Xbox Live account? Yes, on every version

💾 What Actually Carries Over?

Here is the good news, and it is a big deal. If you buy Sea of Thieves on Steam yourself, your progress absolutely carries over. Why? Because every Sea of Thieves player has an Xbox Live account, no matter which storefront or platform they use. That account is basically your pirate identity. When you launch the game on Steam, you sign in with the same account, and your pirate is waiting.

And when Rare said progress carries over, it really meant everything. Think about all the time you spent unlocking cosmetics, leveling up your reputation, and saving gold. All of that follows your Xbox Live account:

  • All cosmetics transfer

  • All reputation and ranks with the trading companies transfer

  • All earned currency transfers

This system is actually pretty player-friendly once you understand it. You are not starting over just because you switched to Steam. You are simply choosing a new front door into the same pirate world.

🖥️ System Requirements and Availability

The FAQ also covered some practical details. At launch, Sea of Thieves still required Windows 10, even on Steam. By 2026, the safe way to think about it is that you will need a modern Windows PC to run the game smoothly, but the core requirement has not changed much. Rare also confirmed that the Steam release would be available in all regions and countries where Steam operates, and the team added more language support for the Steam launch.

🌊 Why This Setup Still Makes Sense in 2026

Would I prefer Sea of Thieves to be completely free-to-play so I could jump between storefronts without buying another copy? Sure, that would be convenient. But the current model keeps the microtransactions from becoming even more aggressive. Sea of Thieves is a live-service game, but your progress is tied to your Xbox Live account, not to the place where you purchased it. That is why cross-play works so smoothly between all platforms and storefronts.

So no, existing players were not given a free Steam copy. But if you did decide to buy it on Steam, you did not lose your pirate, your cosmetics, or your hard-earned gold. And in 2026, that kind of cross-progression is still one of the best things about the Sea of Thieves experience.
