Here are the key takeaways identified by Blask:
Offshore still dominates. Despite growing domestic momentum, unlicensed operators control roughly two-thirds of total U.S. market volume by CEB (Competitive Earning Baseline), which Blask defines as a projected revenue a brand should realistically capture given its market presence.
Full‐spectrum regulation works — but takes time. Six out of seven fully regulated states (offering both online casino and sports betting) have tipped the balance toward domestic operators, averaging ~62% domestic CEB. Michigan leads at 75%, while Rhode Island — the youngest fully regulated market, operating as a lottery‐run monopoly — remains below 50%. Channelization is a multi‐year process, not a switch.
California and Texas are the biggest untapped prizes. Together they represent nearly $10B in CEB — entirely offshore. As standalone countries, California would rank 8th globally by CEB, Texas — 9th.
Without casino, offshore fills the gap. Betting‐only markets average 74% offshore, and the ceiling is structural: of 24 states with online betting but no licensed casino, only 2 (Maryland, Arizona) have achieved domestic CEB above 40%. Players seeking slots and table games are pushed offshore by default.
