One of the SEC's 2020 amendments[1] to the expanded accredited investor definition was to include anybody with a FINRA Series 65 license[2], among other changes.
The Series 65 license is one of the few FINRA licenses that do not require sponsorship[3] and costs $187[4]. This low price of entry seems to be pretty accessible to most people if they have the desire to access riskier and/or more sophisticated gambling^Hinvestment opportunities.
