Once Shadowkeep is released, all players regardless of what content they own will receive an automatic bump to 750. [quote]We’re setting the Power this Fall to 750 for both returning and new players. We want you to all be together when Shadowkeep opens. Here’s what this means: - Every single item in the game is being raised to a Power floor of 750 when Shadowkeep and New Light launch. Every item in your inventory (and vault) is going to automatically jump to 750. - It's like a free global burst of infusion for all players.

At the moment I don’t believe he can. Once October 1st rolls around he’ll get Forsaken and some of the new season for free. I think anyone will be able to hit the current max cap from that point on. Edit: Forsaken won’t be free
