Polymarket sports whales: big positions on games that end tonight
Markets that live for an evening
A Polymarket sports market is usually one game: "Giants vs. Rams", "Will Bayer 04 Leverkusen win on 2026-10-15?", a tennis match in Barranquilla. It asks about one game and is settled on that game's result (how resolution works), so it lives for hours where an election market lives for months.
That makes the Polymarket Sports Whales feed the fastest-moving of the category feeds, and the one where the time an alert arrives matters most. It reports every trade of $20,000 or more on these markets; size is its only filter.
The numbers, 3 September to 27 October 2026
Over those 55 days the feed recorded 2,398 positions on 1,440 markets, from 512 wallets — about 44 a day, and 76 on the busiest. These are positions our pipeline recorded, not messages anyone received.
| Sports | Macro | Politics | |
|---|---|---|---|
| Positions of $20,000+ | 2,398 | 232 | 115 |
| Median time to the market's listed end | 3 hours | 41 hours | 18 days |
| Opened at 85¢ or more | 31% | 61% | 60% |
Three things follow. The feed is loud: switched on with the other category feeds, it will be most of what you receive. The window is short: three quarters of the positions came within 24 hours of the market's listed end, and 21% after it, while the game was being played. And the prices are mid-range: the median position was opened at 62¢, where on politics and macro most money went onto outcomes already priced near certainty.
Head-to-head markets ("X vs. Y") were 73% of the positions. American football drew the largest clusters — 18 positions worth about $1.34 million on Giants vs. Rams alone — and the busiest days in UTC were Tuesday and Monday, which is when Monday and Sunday evening games in the US are played.
Reading one alert
Look at the time to the end first. A position an hour before kick-off is placed on the line-ups and the news of the day; one placed after the listed end is placed on the game as it stands. Then the price: at 62¢ a $30,000 position returns about $18,400 if it wins, and loses $30,000 if it does not.
Then the wallet line. Polymarket publishes a profit board for sports (Polymarket's leaderboard), and two positions in five in our window came from wallets with a placement on it or on the global board. Most did not, and for those the size is all the alert can tell you.
Plan and delivery
Polymarket Sports Whales is a Pro feed, delivered to Telegram and to the Darkmen web feed, whichever you switch on. What each plan includes is on the pricing page.
FAQ
How busy is this feed?
Far busier than the other Polymarket category feeds. Over our 55-day window it recorded 2,398 positions of $20,000 or more — about 44 a day, 76 on the busiest — against 232 for macro and 115 for politics. Switched on alongside them, it will be most of the Polymarket messages you receive.
Why do positions arrive after the market's end time?
On a game market the listed end time is usually around the start of the game, and trading carries on while it is played. 21% of the sports positions in our window came after that listed time, so an alert can describe a position taken in the second half.
Does the alert show if the wallet is a sports specialist?
Polymarket keeps a separate profit board for sports, and the alert shows a wallet's placement there or on the global board when it has one. About two positions in five in our window carried one. A placement is a record of past profit, not a prediction for this game.
How fast does it arrive?
Darkmen reads Polymarket's public trade feed every 15 seconds. On a market that may settle in three hours, that is the part of the feed that matters most.
Which plan is this on?
Pro. Polymarket Sports Whales is one of the Polymarket feeds that come with the Pro plan.
