Your own prediction market for group chats: friends open small capped markets on real life, settled by a named panel with evidence.
Try it live, freeYour USDC is locked in a smart contract, not sent to us. The contract lets us collect it only if we deliver within 14 days of your payment (by 15 Nov 2026 if you pay today). After that date, if we have not collected it, you take it back yourself from My apps, no permission needed. Before it, only we can refund: if we miss the promised date, ask in My apps and we refund you from the contract. View the contract on BaseScan. This covers every payment, a reservation too: the funds are released to us only when we deliver.
Promised delivery: 4 Nov 2026 (counted from payment). Self-refund opens: 15 Nov 2026 (the contract deadline).
Add-ons are not part of this payment. Once your app is delivered you can request them from My apps, and you only pay if you say yes to the quote.
Tomás Herrera plays five-a-side every Tuesday in Valparaíso, and his group chat spends all week arguing about whether Nico will really finish the Santiago marathon under four hours. With Group Odds he opens a market inside the Telegram group, everyone takes a side with play chips or a few capped dollars, and three named friends settle it by posting Nico's race result as evidence. The argument becomes a game with a fair ending instead of a fight.
The group member app: Telegram mini app and web link, market feed per group, market builder with cap, close time, criteria and panel, play chips or capped USDC positions, panel settlement with evidence and a dispute window, the group ledger with receipts, and the member profile with plans.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Group chat prediction markets already exist: Telegram bots for private group markets, Polymarket bots like OkBet, FAFO, StakeSocial on XMTP and play money apps like Bettie. What is new here is the settlement design for people who know each other: a named three person panel chosen when the market opens, who must attach evidence before a result counts, with a dispute window, hard stake caps per person and play money as the default.
PredictionMarketsBot (private markets inside a Telegram group), FAFO (markets from group chat claims, demo funds), StakeSocial (XMTP group betting), Bettie (play money leagues). None found with a named evidence panel as the resolution method.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
3 live races fit this app. Each one says why, with its prize and countdown. The rule on existing code is on the race page.
A complete group chat prediction market you own: friends open small capped markets on real life inside Telegram, named panels settle them with evidence, and your console runs plans, group rules, growth and the bot.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Groups play free with chips. Groups that want capped USDC mode, unlimited markets and season leaderboards pay a small monthly plan, and organizers running several groups pay for League. An optional settlement fee on USDC pools goes to the owner.
Optional settlement fee of 0 to 2 percent of USDC pools (default 1 percent), paid to your wallet and shown on every payout. Play chip markets never pay a fee.
Prices are yours to set. Illustrative, not a promise of income.

Your brand, caps, chip amounts, chain choice and integrations such as WhatsApp or Discord bots, custom evidence types or a league site on your own domain are scoped and priced together.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Friend groups argue about real life all the time: will he finish the marathon, will the barbecue survive the rain, will she actually move to Lisbon. Public prediction markets do not list these, and informal bets end in arguments about who won and who still owes money.
This largely exists. Telegram bots already run private markets inside a group, Polymarket bots bring public markets into chats, and play money apps run friend leagues. Group Odds is an incremental take focused on fair endings: a named panel of three members is chosen when the market opens, a result only counts when a panelist attaches evidence, other panelists confirm, anyone can dispute within a window, stakes are capped per person, and play chips are the default. Research verdict: exists, low novelty.

Turn the arguments friends already have into small, fair games with an ending everyone can see and accept.
The panel names Every market shows the three friends who will settle it. People play more fairly when they know who is judging.
Evidence or it did not happen A result needs a photo, link or file attached and a second panelist to confirm. The evidence stays pinned to the market.
The settled card When a market closes, a card posts back to the group with the result, the evidence and who called it right.

Cost per use: unlocked when your app is paid in full.
Every settled market posts a card back into the group with the evidence and who called it. Friends in other groups see it and ask for the bot. Group admins invite the bot; there is no outreach to strangers.

Every group chat already runs informal bets on real life, and most of them end in an argument about who won. Owning Group Odds means you run the fair version: small capped markets inside the chat, play chips by default, and a named panel of friends who must show evidence before anyone is paid. Groups play free, and the ones that want more pay a few dollars a month. Prediction market rules differ by country, so you check yours before you ever turn on money mode.
With money it can be, and rules differ a lot by country and state. That is why play chips are the default and USDC mode stays off until you have checked local law. Many owners run chips only for a long time and earn from plans for features, not from stakes.
The panel is named before anyone takes a side, a result needs evidence and a second panelist, and anyone can dispute within a day. Caps keep stakes small. Markets about someone's health, safety or private life are refused.
Most groups will play free forever, and that is fine: they are your growth. The groups that run a season, want a leaderboard or want capped USDC pay $3 a month. Start with your own groups and see which features they ask for.
Bots that spam get banned. Group Odds only posts when a market opens, closes or settles, only in groups that added it, and never messages strangers. Follow Telegram's bot rules and keep it that way.
Monthly plans per group and per organizer, plus an optional small settlement fee on USDC pools where money mode is legal.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
