Very likely PC After PC release
Roleplay servers (FiveM-style)
Run or build on dedicated roleplay servers and earn through subscriptions, donations and in-server perks. This is the most proven GTA earning model — it already powers a large economy on GTA Online via FiveM, which Rockstar now sanctions.
Tech: FiveM / Cfx.re, Lua + JavaScript, Tebex payments
Likely Console & PC At launch
Selling assets on the official marketplace
Create and sell mods, vehicles, skins and props through Rockstar's official paid marketplace. Because it is first-party, this is the most likely earning route available on consoles at or near launch — no sideloading required.
Tech: CFX Marketplace, in-game / web creator tools
Likely Console & PC Online phase
Custom missions, races & modes with engagement payouts
Build custom missions, races and game modes with official Creator tools and earn a share of revenue based on how much they are played — the Fortnite Creator Economy 2.0 model. Strongly signaled by Rockstar's Creator Platform hiring, but payout terms are unconfirmed.
Tech: In-game Creator tools + web creator platform (JavaScript)
Possible Console & PC Online phase
Sponsored brand maps & experiences
Build branded experiences or maps in partnership with real-world brands, as creators do with Fortnite islands. Plausible in a mature GTA 6 Online creator economy, but depends on Rockstar opening IP/brand rules to creators — still a rumor.
Tech: Creator tools + Rockstar IP / brand partnerships
Possible PC After PC release
PC mods (single-player & custom content)
Create single-player mods and custom content for the PC version — sold or donation-funded. This only becomes possible after the later PC release, since consoles do not allow traditional modding, so it is a post-launch opportunity.
Tech: OpenIV-style tooling, script hooks
