### Questions people ask

Is HRT a lead market maker (LMM)? Yes. HRT is the lead market maker (LMM) for 6 US ETFs on the lists NYSE Arca publish. Lead market maker per NYSE Arca, as of Oct 23, 2026.

### Method

Each row is one ETF on one listing exchange’s own list of the market makers it assigns: NYSE Arca’s list of its listed ETPs and their lead market makers, Cboe BZX’s LMM Securities list and Nasdaq’s ETF definitions, where the role is called Designated Liquidity Provider (a Market Quality Supporter is not counted). ETFIQ reads each list once a week as ETFIQ, credits it to its exchange beside every figure, and keeps only the ETFs it covers. A firm is joined to its authorized participant page only where its name is, letter for letter, a broker-dealer’s registered name on the SEC’s list and that registration is the AP firm’s. An exchange that refuses the read shows as not published, with the day.
