The beta is available for the Google Pixel, Pixel 2, Sony Xperia XZ2, Essential Phone, Nokia 7 Plus, Xiaomi Mi Mix 2S, Oppo R15 Pro, Vivo X21, and even the unannounced OnePlus 6. Unfortunately, Nexus users are out of luck as support for Nexus devices was dropped this year. If you signed up for the Android Oreo beta program last year, you'll still have to sign up again, as the registration doesn't roll over. The P Developer Preview downloads page also warns that devices which were manually flashed to the DP1 release may not receive the OTA to DP2 as part of the beta program, so it's possible that you may have to manually migrate to DP2.
It'll be a while before the OTA hits your device, so you might have to wait a bit. Head over to the link above to check if your device is eligible and tap on the opt-in button. Do note that you might have to flash the final build on your device once it's out, as it may not be rolled over OTA for beta users.
