Saturday night recap: esports and college football draw the whale money
Between roughly 7 and 11 pm Toronto time on Saturday, WhaleGrader logged 192 Polymarket trades of $10k or more, worth about $8.8M combined.
Where it went
- LoL Worlds: Dplus KIA vs T1 – about $1.24M across 21 large trades, the busiest market of the night.
- Wizards vs. Bulls – about $1.04M in 8 trades.
- Ole Miss vs. Texas – about $0.85M in 14 trades.
- 76ers -12.5 spread – about $0.73M in just 4 trades.
Sports and esports made up nearly all of the size. That is normal for a weekend night: these markets settle within hours, so whales can turn money over fast.
How much should you read into it?
Not much on its own. Across 10,699 graded whale flags, whales were right 54.5% of the time. Based on the prices they paid, they should have been right 58.1% of the time. That gap, the edge, is about -3.7 points: on average, big trades did slightly worse than the odds already implied.
Plain English: a big trade means someone is confident, not that they're right. The useful signal is in specific wallets with long, positive records. See Smart money and the track record.
Jargon
- Whale flag – a single trade of $10k or more.
- Graded – the market resolved, and we checked whether the whale's side won (CALLED) or lost (MISSED).
- Edge – hit rate minus the hit rate the entry prices implied.
