OTCQB vs OTCQX: What's the Difference Between OTC Tiers?

OTCQX and OTCQB are the top two tiers of OTC Markets. OTCQX is the highest tier with the strictest requirements — companies must meet financial standards, have audited financials, and maintain a minimum bid price. OTCQB is the venture tier for early-stage companies that are SEC-reporting. Both are significantly more transparent than the Pink tier.
