The three NBA tipoff games on Tuesday night produced a combined $114 million in trading volume on Kalshi -- about as much as three typical NFL games. OKC/SAS > PHI/NYK by a smidge.

Sunday on Kalshi: Another volume record at $3.04 billion, just a few bucks ahead of Saturday. It is the sixth time Kalshi has bested its own single-day record in September. Rams/Broncos moves to #2 on the list of NFL regular-season games, behind only Colts/Chiefs in Week 2.

Nah, Kalshi has a fee accumulator to prevent rounding-up from costing you more than 1c per market. So it's maybe losing $26.13/day not $432/day. Likely just someone farming volume for a higher rate limit tier if I had to guess!

Kalshi did $15.3 billion in notional volume last week. About 60% -- or $9.1 billion -- of that volume was on parlays, which are almost entirely based on sports events. My read is it's going to be increasingly difficult to frame this as non-gambling activity. Data per @TickerTracker_
