If the thousands of people sitting in the menu of Battlefield 6's open beta before it even became playable didn't give it away, the upcoming FPS is looking rather popular. So popular, in fact, that now that the beta's doors have finally opened, it already has the highest concurrent player peak out of any other game in the series on Steam.
As spotted by PC Gamer, at the time of writing, Battlefield 6's open beta has a concurrent player peak of 334,549 according to SteamDB. I say "open," but currently, the beta is actually in early access, and although you can watch Battlefield 6 streamers on Twitch to get access to the Battlefield 6 beta yourself (assuming you hadn't met the previous requirements), I still imagine that slight complication could mean the number might surge further when things become open to everyone on August 9.
