The official REX Shares press release confirms RAM is a 2x leveraged ETF tracking DRAM, launched June 24, 2026 (a Wednesday), matching the claim's description of the fund and its debut day. The linked Kobeissi Letter source directly supports the ~$380 million first-day notional volume figure and the assertion that this is a record for US-listed leveraged/inverse ETFs, citing the prior SpaceX-ETF records it surpassed. An independent Substack analysis corroborates the record debut. The only discrepancy is a secondary source citing ~$400M versus the ~$380M figure, which is minor and likely reflects rounding or differing measurement; both agree on the record status.
