Understanding US Rule 506(b) Private Placements
What Is Rule 506(b)?
Rule 506(b) under Regulation D lets companies raise unlimited capital from accredited investors—and up to 35 non-accredited but “sophisticated” investors. There are no advertising rules but strict anti-fraud provisions.
Key points:
– Unlimited funding cap
– No general solicitation
– Disclosure only if non-accredited investors are involved
Who Qualifies?
An accredited investor usually has:
– Net worth over USD 1m (excluding primary residence)
– Income above USD 200k for two consecutive years
A sophisticated investor may lack those thresholds but has enough experience or professional advice to assess the risks. Many UK investors fall in this bucket when assessed by issuers.
Pros and Cons
Pros
– Flexible fundraising
– No limit on investment amount
– Fewer paperwork requirements
Cons
– Limited to defined investor classes
– Higher compliance on anti-fraud
– Potentially less transparency
UK SEIS and EIS Schemes Explained

– Up to 50% capital gains exemption
