Example

Dota 2: Team Yandex vs BetBoom Team (BO3) - BLAST Slam Group

Yandex is in the best form
with many winning streaks until now. Not sure BB can handle this.

Real call, receipt here. Its read is 18 words. A call is listed only with your own reasoning, 15 words or more about the matchup: without it the call waits, and you have 5 minutes to add it by editing your message or replying under it. The reasoning is kept verbatim on the receipt and it is what people follow you for. Keep the pick on its own line, and name only the side you are backing there, not both teams. The price is optional: your entry is the order-book ask at the second you posted.

Then what

  • It appears on Open calls, and grades itself when the market resolves.
  • Want out early? Reply #close to your own call.
  • Scoring, prizes and limits: Season 2. Pricing and grading in detail: Methodology.

Combos (Season 2)

A combo backs 2 to 6 picks on different fixtures as one 1u position. It loses as soon as a leg loses and wins when the last leg wins.

  1. Put #combo in the message that lists the legs. #nfa goes in the same message, or in another of your messages within 5 minutes, exactly as for a single.
  2. Write one leg per line, 2 to 6 legs. Each leg line reads [number] <anchor> [:] <pick> [price].
    • Number (optional): 1), 1., Leg 1:, -, • or *, followed by a space.
    • Anchor: a jup.ag/prediction/POLY-… link, a polymarket.com event, sports or markets link, or a matchup such as Team A vs Team B. Team A v Team B, Team A vs. Team B and Team A x Team B (with a space each side of the x) work too.
    • After a matchup, put a colon before the pick: Team A vs Team B: Team A. A pipe (|), a comma, two spaces, or a hyphen with a space each side (Team A vs Team B - Team A) also work. After a link, no separator is needed.
    • Pick: the outcome as the market names it: Arsenal, Draw, Over 2.5 goals, BTTS yes, Sinner -1.5 sets.
    • Price (optional): 62c, @ 62c or 62¢. It prices only its own leg, and it can only make the entry worse, never better.
    • A link or matchup alone on a line takes its pick from the next line, if that line has 12 words or fewer and no link or matchup of its own.
    • A matchup line whose pick runs past 12 words counts as part of the read, not as a leg.
  3. The read: every other line (tags removed) must reach 15 or more words of your own reasoning, the same rule as a single. Or reply under the combo with the read within 5 minutes.
  4. A combo price or stake you write yourself is ignored. The stake is always 1u, and the price is always computed from the legs.
#combo #nfa
1) https://jup.ag/prediction/POLY-<A> Arsenal @ 70c
2) https://jup.ag/prediction/POLY-<B>
Sinner
3) Real Madrid vs Barcelona: Over 2.5 goals 58c
Arsenal have won six straight at home and Wolves have one away point all season, Sinner has not dropped a set indoors this year, and Clasicos at the Bernabeu average over three goals.
  • Leg 1: the ask at the post is 68¢ and the message says 70¢, so the entry is 70¢. A call never pays more than the caller stated.
  • Leg 2: the link is alone on its line, so the pick, Sinner, comes from the next line. Ask 64¢, entry 64¢.
  • Leg 3: the matchup finds its fixture and “Over 2.5 goals” its market. The message says 58¢ against an ask of 60¢, so the entry is 60¢: the book above the claim wins.
  • The price: 70¢ × 64¢ × 60¢ = 26.88¢. A win pays 100 ÷ 26.88 − 1 = +2.72u; a loss is −1u.

Two legs, one on a matchup, and what a void does:

#combo #nfa
Swiatek vs Gauff: Swiatek 48c
https://polymarket.com/sports/epl/epl-che-liv-2026-10-04 Chelsea 45c
Swiatek has beaten Gauff in their last five meetings on hard courts, and Chelsea have lost once at home all season against the top six.
  • The price: with asks of 48¢ and 45¢, 48¢ × 45¢ = 21.60¢. A win pays 100 ÷ 21.60 − 1 = +3.63u.
  • A void: if the Chelsea match resolves 50/50, that leg is void. The combo is repriced to 48¢ and grades as the Swiatek single: a win pays +1.08u, a loss is −1u.

What counts

  • Each leg enters at 10¢ to 90¢, and the combo at 10¢ to 90¢, so a win pays at most about +9u. A combo outside the bands, with 7 or more legs, or with two legs on one fixture is recorded with its receipt but does not count. Legs at 40¢, 45¢ and 50¢, for one, make 9¢: below 10¢, so that combo does not count.
  • Up to 15 combos count per season week (it resets Thursday 00:00 UTC). Each is one of your 30 weekly calls and one of the 10 you need to qualify.
  • A void leg drops out and the combo is repriced; with one leg left it grades as that single.
  • A combo cannot be closed early, and it cannot be fixed later than 5 minutes after posting without a human.

Every combo gets its own receipt, linked from your profile and from Open calls. The full rules are on the Season 2 page.

Add your wallet (optional)

Back your calls on Jupiter and let the receipts say so. Sign in with Discord on Add your wallet and paste the address of the Solana wallet you trade with. There is nothing to connect and nothing to sign. From then on each Season 2 call shows “Traded on Jupiter” when a wallet you added bought the side you called on Jupiter Prediction, from 24 hours before your post until the market closes, or “No Jupiter trade found in linked wallets” when none turned up. It never changes your score. Your address stays private unless you choose to show a shortened form. Unlink any time.

How the check works

Adding a wallet is opt-in. A wallet is added by the caller and is not ownership-verified; the chip says a wallet they added bought that market inside the call window. A wallet belongs to one caller at a time, and a caller can add up to 3. The check reads those wallets’ public Jupiter Prediction history and looks for a buy of the called side on the called market, from 24 hours before the post until the market closes or the call is graded. Sells, the other side, parlays, free entries and trades outside the window do not count, and markets Jupiter does not list show no chip. The neutral chip appears from 60 minutes after a post, once every linked wallet has been checked. Combo legs show “Traded on Jupiter” only: parlay tickets cannot be matched yet, so no leg says a trade is missing. Chips reflect the wallets linked now, so unlinking removes them. Season 2 calls only, and never a scoring input. The rules in full are on Methodology.
