INSANE: The Proshares GENIUS Money Market ETF IQMM saw $17b in Day One volume yest. That is multitudes beyond the all-time record for an ETF. For context IBIT did $1b. BlackRock's ESG ETF seeded by pensions did $2b. This is like 8x that. Has to be BYOA, but still, unreal. That $17b is going to show up as flows/assets tonight. Where is $ coming from? Either way I was wrong about this ETF, I just figured it would be niche at best as ppl would use BIL or SHV as money mkt subs.(Eric Balchunas)
