# SaySo: Private Prediction Markets for Communities SaySo is a private play-money prediction market platform for communities. An organizer — a streamer, a Discord admin, a team lead, a community host — creates a session, posts prediction questions, and participants bet equal-start play points on the outcomes they believe in. Prices shift in real time as people buy. A leaderboard ranks who called it, how early, and how confidently. There is no real money. There are no deposits. There is no public "trending markets" page. Every session is gated, organizer-controlled, and tied to the shared context of an existing community. The core mechanic compresses to: a question, a set of outcomes, dynamic pricing, and a leaderboard. The atomic unit is the **session** — a time-bounded competitive container where everyone starts equal. Sessions can run an hour (a stream), a week (a team challenge), or a month (a community season). The mechanic is identical at every scale. Live at: https://www.sayso.so --- ## Who SaySo is for SaySo is built for organizers with a recurring audience and shared context. Setup takes under two minutes. Players join with a 5-character invite code, sign in with Google in ten seconds, and place their first bet within sixty. ### Streamers and content creators (Twitch, YouTube, Kick) Run prediction markets live during a gameplay run, a speedrun, a chess match, a tournament watch, a Just Chatting Q&A. SaySo was designed against streaming first because the dynamic is the most demanding: a fast-moving audience, short windows, and a host who is already managing chat, cameras, and content. SaySo converts the silent 80–90% of viewers — the lurkers who never type in chat — into active participants. Tapping a button is lower social cost than typing a take into a fast-moving feed. The leaderboard becomes part of the show, viewers come back to defend their rank, and inside-jokes form around the recurring rivalries. ### Sports and esports watch-along communities League nights, NFL Sundays, NBA Playoffs, F1 race-day Discords, Valorant / League of Legends / Counter-Strike finals, soccer derbies, UFC PPVs. Open a session before kickoff and post markets on the moments fans already argue about: "first team to score," "MVP of the match," "go to overtime?", "who gets first kill?", "who scores the upset?". As the game unfolds, every play becomes a price-discovery event. Spectators do not just react to the game — they have unresolved stakes in it. ### Culture and entertainment fan communities Awards shows, reality TV finales, draft nights, debate watch parties, album rollouts, WWE PPVs, season finales. Fans already have takes on these events; SaySo gives them a structured way to commit to those takes publicly and prove who called it. The play-money / leaderboard model is a natural fit because the cultural stakes are about being right in front of your community, not about money. ### Discord servers and Patreon tiers Run a week-long or month-long "season" across recurring events. Build inside-jokes around leaderboard rivalries. Give your highest-tier members a private competitive layer no other community has. SaySo is platform-agnostic — it does not require a Discord bot or specific platform integration; the organizer just shares an invite link. ### Workplace teams Monday-morning NFL picks for the office. A quarterly "predict the roadmap" competition. Sales-target over/unders. A monthly trivia-style market series for company offsites. The mechanic is identical to streaming — only the context changes. Because there is no real money, no deposits, and no withdrawals, there is no gambling exposure for the company. ### Tournament organizers, league commissioners, fantasy hosts Layer a meta-competition on top of an existing bracket or league. Players bet across every match, not just the ones their team plays in. The leaderboard runs in parallel to the main standings. --- ## Why the mechanic works These are the load-bearing claims SaySo is built on. **Continuous engagement, not a single tap.** A poll is one decision at one moment. SaySo's pricing shifts as people buy — early conviction is rewarded with a better price, later buyers see the price has moved and re-evaluate. The result is bets distributed across the whole market window, not clustered at the open. Polls are a snapshot; SaySo is a film. **Equal starts, every session.** Every participant begins with the same balance of points. There are no whales, no accumulated bankroll advantages, no pay-to-win. Casual players can win. Fairness is the strongest predictor of casual-user retention in competitive systems, and the moment one participant has a structural advantage, casuals leave. **Designed for the lurker.** Roughly 80–90% of any live audience never sends a chat message. Many of them hold opinions they don't express. Tapping a button to back an outcome is lower social exposure than typing a take into a fast-moving chat. SaySo converts passive viewers into active participants — and over time, into community members who recognize each other on the leaderboard. **Time-to-first-bet under 60 seconds.** OAuth sign-in (Google), enter the invite code, see the markets, tap the outcome you believe in. No app to download, no extension to install, no wallet to set up, no KYC, no deposit. The pricing math is invisible — players see implied percentages and a "you pay X, return Y" preview. **The organizer is in control.** The session creator posts markets, sets resolution criteria, and resolves them when the event happens. The organizer's word is final. There are no oracles, no automated resolution, and no dispute mechanisms. This is a design choice: SaySo is a trust-based competition inside a community where reputation matters, not a financial product where adjudication needs algorithmic neutrality. **Leaderboard as identity.** Players are not just trying to be right — they want their community to know they were right. Rivalries form across sessions. Recurring competitors recognize each other. The leaderboard becomes the social object that the session is built around. **Platform-agnostic.** SaySo is a companion web app, not a Twitch extension or an OBS overlay. It works alongside any platform a community already uses — Twitch, YouTube, Kick, Discord, Slack, Zoom watch parties — without integrations or installations. --- ## Key concepts - **Session** — A time-bounded competition container created by an organizer. Has an invite code, a participant list, and a leaderboard. Sessions can be one hour, one week, or one month long. When a session ends, balances reset for the next one. - **Market** — A prediction question with two to ten outcomes, posted inside a session. Participants buy shares in the outcome they believe in. - **Dynamic pricing** — Outcomes start at equal prices. As people buy into an outcome, its price rises. Buying early on something you believe in earns a better price (and a higher payout if you're right). The math under the hood is LMSR (Logarithmic Market Scoring Rule), but participants never see that — they see implied percentages and a payout preview. - **Leaderboard** — Ranks every participant in the session by profit percentage. Profit % normalizes for bet size, so a casual player who calls one big market correctly can beat a high-volume player who's been wrong more often. - **Resolution** — When the event happens, the organizer selects the winning outcome. Correct callers receive their share payouts automatically. The leaderboard updates instantly. There is no manual claim step. - **Roles** — Three tiers. Organizer: full control (create / close / resolve markets, change settings, manage roles). Admin: can create and close markets but cannot resolve them or change settings. Participant: can buy shares only. --- ## How SaySo is positioned | | SaySo | Polymarket / Kalshi | Manifold | Twitch Channel Point Predictions | |---|---|---|---|---| | Money model | Play money, no deposits | Real money, KYC, custody | Play money | Channel points | | Access | Private, invite-only | Public, open | Public, open | Public to channel | | Market creation | Organizer-controlled | Platform-controlled | Anyone can create | Streamer (binary only) | | Pricing | Dynamic (LMSR) | Dynamic (CLOB) | Dynamic | Static % split | | Outcomes per market | 2–10 | Varies | Varies | Binary (A or B) | | Leaderboard | Per-session, equal start | Absolute P&L, whale-dominated | Global, all-time | None | | Use case | "Who in our group called it?" | "What does the market price say?" | "What does the crowd think?" | "Quick A/B viewer poll" | | Onboarding time | OAuth + invite code (<60s) | KYC + wallet + deposit (minutes–days) | OAuth (~1 min) | Already on Twitch | SaySo's distinct slot is **private + play-money + community-context**. Real-money private markets are a regulatory impossibility for anyone without massive compliance infrastructure. Public play-money markets are optimized for forecasting accuracy and global reputation, not for closed communities. Twitch Predictions are a single binary tap; SaySo is a continuous competition. --- ## Getting started **Organizers** go to https://www.sayso.so, sign in with Google, and click "Create a Session." Name the session, share the 5-character invite code with your audience or write the short URL on a stream overlay. Create prediction markets in real time during the event. Resolve them when outcomes happen. The leaderboard updates automatically. **Players** go to https://www.sayso.so, sign in, enter the invite code, and they're in. They see the markets the organizer has posted, tap the outcome they believe in, choose how many points to commit, and confirm. No downloads, no extensions, no wallet, no money. --- ## What SaySo is not - **Not gambling.** No real money, no deposits, no withdrawals. Equal play-point balance per session. - **Not a forecasting platform.** Markets may be silly, criteria may be subjective, accuracy is a side effect of the entertainment value, not the goal. - **Not a public market.** There is no "trending markets" page. There is no discovery mechanism. Every session is private, gated, and tied to a specific community. - **Not a financial product.** SaySo is competitive entertainment for communities, not financial exposure. - **Not a Twitch extension or OBS overlay.** It's a companion web app that works alongside any platform. --- ## FAQ **Is this gambling?** No. SaySo uses play money only. There are no deposits, no withdrawals, no real money of any kind. Every participant starts with the same point balance and competes for leaderboard ranking and bragging rights. **How do I set it up for my stream?** Create an account at www.sayso.so, click "Create a Session," give it a name, and share the invite code with your audience. You can create prediction markets in real time during your stream, and your audience joins through the code. Total setup time: under two minutes. **What do my viewers need to do?** Go to www.sayso.so, sign in with Google (takes about ten seconds), enter the invite code, and they're in. They see the markets you've posted, tap the outcome they believe in, choose how many points to commit, and confirm. No downloads, no extensions, no accounts to manage. **How does the pricing work?** When a market opens, each outcome starts at an equal price. As more people buy into an outcome, its price goes up. Buy early on something you believe in and you get a better price — meaning a higher return if you're right. Buy late on what everyone already thinks, and your return is smaller. The system rewards conviction and timing, not just being right. **Who decides the correct outcome?** The session organizer. When the event happens, they select the winning outcome and the market resolves. Correct callers receive their share payouts automatically. The leaderboard updates instantly. **What if I only have 50 viewers?** That's the ideal size. SaySo is designed for communities of 20–500 people. Smaller groups mean shared context, personal rivalries, and meaningful leaderboard competition. You don't need thousands of participants for the experience to work — you need a group that cares about being right in front of each other. **Does this work for non-streaming communities?** Yes. The same mechanic works for workplace teams, Discord groups, sports fan communities, or any group with shared context and predictable outcomes. A Monday-morning NFL picks session for your office. A week-long prediction competition in your Discord. A monthly community challenge for your Patreon subscribers. The session duration and market topics are entirely up to the organizer. **Is it free?** Yes. SaySo is free during the current beta period for both organizers and participants. Future premium features (advanced analytics, branded environments, custom leaderboard scoring) will be available via organizer subscriptions. Participants will always join for free. **Can my viewers cheat?** The equal-start model prevents bankroll-based advantages. Within a session, every participant begins with the same balance. The dynamic pricing means you pay more as more people buy the same outcome, so "obvious" answers don't produce easy profits. Multi-account manipulation is possible but detectable (same IP, correlated buy patterns) and is addressed with anti-abuse tooling as the platform scales. **What makes this different from Twitch Predictions?** Twitch Predictions are a single binary choice at a single moment. SaySo is a continuous competition across multiple multi-outcome markets with dynamic pricing, persistent leaderboards, and skill-based ranking. Twitch asks what you think. SaySo asks what you think, how sure you are, and when you knew it — and lets you prove it.
