PrognosX and other Polymarket whale trackers
We compared what each service shows as its record, whether it bets its own money, which languages it speaks and what it costs. Checked on their websites on 14 November 2026 — prices and features may change.
| Service | Focus | What the record shows | Own money at stake | Languages | Price |

| 0xInsider | US sports and esports | Their own pick-of-the-day record | No | English | From $99 a month |
| Polywhaler | All markets; sports is one section | Wallet leaderboard — the whales' own profit | No | English | Paid plans |

The key difference
Most trackers show how much the whale made. But you never get the whale's price — you buy later and higher. PrognosX counts every result at the price we could actually buy after our delay, and our robot bets its own money by the same rules: the wallet is public.
Is PrognosX free?
Yes: big bets with a 30-minute delay, the robot's record and settled bets, one AI question a day. The side of a whale bet before kick-off is in Pro ($9 a month, 3 days free, 7-day refund).
Does PrognosX copy bets automatically?
No. We show the bet, the odds and the record — the decision is yours. In Ultra we also show how much to stake from your own bankroll.
Do you promise profit?
No. Analytics, not betting advice. 18+.
