Short notes on what the tape is arguing about. Figures are the ones being posted publicly. When two posts disagree, both numbers stay in the note.
On 22 September the Bitcoin ETF tape was quoted as both about $715 million and about $1 billion. They are not the same print.
Hyperliquid posted an $18 billion open-interest high. The fight underneath is whether a perps exchange can wait on a scattered validator set.
BitMEX ended exchange operations at 04:00 UTC on 23 September 2026. Withdrawals stayed open. New deposits did not.
Kalshi asked the CFTC about margin on prediction contracts. Polymarket's tape was politics, bans, and volume.
