I currently run a house-based betting site built in Laravel and I’m ready to transform it into a true peer-to-peer prediction market that functions much like Kalshi. The goal is for users to trade directly with one another instead of with the platform. Core work • Replace the existing “buy-only” workflow with a live order-book where users can post buy or sell orders for Yes/No shares. • Build a matching engine that pairs orders automatically in real time. • Let traders close or unwind positions at any point before settlement so they can lock in gains or cut losses. • Shift price discovery to pure market demand, updating quote calculations continuously and handling partial fills smoothly. • Rework settlement so that, once an event’s outcome is verified, winnings (and any remaining collateral) are distributed to wallet balances without manual intervention. Acceptance criteria – Order book shows depth and last-traded price; orders execute instantly when spread crosses. – Users can place, modify, cancel and partially fill both buy and sell orders from the web UI and through the existing Laravel API endpoints. – P&L and position history update in real time. – Settlement triggers accurately from my admin panel and releases funds according to matched positions. – Code follows Laravel best practices, is fully tested, and comes with concise deployment notes. If you have deep experience with Laravel, matching engines or exchange-style architectures, I’d like to see how you can help me launch this next phase.

Hi there, I can help you convert your current Laravel-based betting system into a proper peer-to-peer prediction market with order book, matching engine, and real-time trading. As you already have the platform in Laravel, I will start with restructuring the current flow from “buy-only” to a full order-based system, where users can place both buy and sell orders. Then I’ll build a matching engine that handles order matching, partial fills, and live price updates based on demand and supply. After that, I’ll implement position tracking and P&L logic, so users can enter and exit trades anytime before settlement. Then we’ll rework the settlement flow, so once the result is declared from admin, funds are automatically distributed to user wallets without manual work. I’ll also make sure the order book, price updates, and user data stay in sync in real-time, so it feels like an actual trading system, not a basic betting app. A couple of things I’d like to confirm before starting: – Do you want real-time updates using websockets or is slight delay acceptable? – Any specific rules for pricing or fees we should follow from day one? I would suggest we connect once, I can walk you through the exact flow and start working on this in phases. Kindly ping me when you’re available. Thanks, Rahul A.

Hello, I understand your goal is to evolve your current Laravel-based betting platform into a true peer-to-peer prediction market with a real-time order book, matching engine, and automated settlement—similar to Kalshi. The key shift here is moving from a platform-driven model to a market-driven system where users trade directly with each other, with accurate pricing, liquidity handling, and position management. I have experience working with Laravel-based systems and exchange-style architectures, including implementing real-time order processing, order matching logic, and wallet-based transaction flows. I can help design and build a robust matching engine that supports buy/sell orders, partial fills, order cancellation, and live updates to positions, P&L, and order book depth. I will also ensure settlement is automated and securely triggered, distributing funds correctly based on verified outcomes. The implementation will follow Laravel best practices, include clean, maintainable code, real-time updates and thorough testing to ensure reliability under concurrent trading conditions. Can we have a quick chat to review your current system and discuss how to structure the matching engine and migration to a peer-to-peer model? Best regards,

Dear Project Owner, I understand you're looking to elevate your Laravel betting site into a dynamic peer-to-peer prediction market akin to Kalshi. With over 5 years of experience in Laravel development and successful implementations of matching engines, I'm well-equipped to take your project forward. To transform your existing workflow, I'll replace the "buy-only" model with a live order book where users can seamlessly place both buy and sell orders. My approach will include real-time order matching, enabling users to adjust their positions fluidly, ensuring that the user experience is both efficient and intuitive. One enhancement I'd suggest is adding an analytics dashboard for users to track their trading history more effectively. In a previous project, I successfully built a matching engine for a trading platform, which resulted in improved user engagement and satisfaction. I estimate this project could be completed in 4-6 weeks. Regards, Khurshid Ahmed

Hi, this isn’t an automated proposal. I reviewed your scope, and this is a transition from a house model to an exchange-style system, which mainly comes down to building a reliable order book + matching engine inside your Laravel app. I’d implement price-time priority order matching (buy/sell Yes/No shares), support partial fills, and maintain a real-time order book with last traded price. Positions and P&L would be tracked at the trade level, allowing users to unwind before settlement. For real-time updates (order depth, fills, P&L), I’d use Laravel Echo/WebSockets, and settlement would be handled as a deterministic backend process tied to event resolution, updating wallet balances automatically. Quick questions: 1. Do you already have a ledger-based wallet system (double-entry), or is it balance-only? 2. What’s your expected order volume/concurrency, so we size the matching layer correctly (queue vs in-memory processing)? Happy to map the data model and matching flow before implementation.

Hi, this project is more than a feature upgrade - you’re turning a house-based betting app into a real peer-to-peer prediction market, so the trading, matching, pricing, and settlement logic all need to work together cleanly in real time. Your priorities are clear, and I can deliver a focused Laravel upgrade that adds a live Yes/No order book, automatic matching, modify/cancel/partial-fill support, market-driven pricing, real-time position and P&L updates, and accurate wallet-based settlement. I’d approach this as a backend + web UI upgrade, with the matching engine, collateral handling, order lifecycle, and settlement flow designed carefully so your existing Laravel APIs can be extended without disrupting current stability. The goal is not just to add features, but to build a solid exchange-style foundation that behaves reliably under real usage. What gives me confidence here is my experience working on structured platforms where real-time state, financial logic, backend workflows, and maintainable architecture all need to operate together cleanly. That includes careful order-state handling, accurate balance accounting, clean API behavior, and strong test coverage around critical logic. If you want this built as a clean, reliable next phase of your platform, I’d be glad to discuss the next step. Best regards, Diah

Hi Patcharee H., Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. How should collateralization work—pre-funded with per-order locks or portfolio (cross) margin—and what are the exact fee model, tick size, and lot size you want enforced (e.g., $0.01 ticks, 1-share lots)? What real-time stack and datastore are in place today (Redis/queues/WebSockets, MySQL vs Postgres), and are there latency/SLA targets for order acknowledgement and match events? Run the matching engine as a single-writer service (Laravel Octane/Swoole) with Redis sorted sets + Lua for atomic match/partial-fill, persisting an append-only trades ledger to the DB; this avoids race conditions and enables fast recovery. Use double-entry ledgering for balances/locked collateral with idempotent settlement and replayable events; expose snapshot+delta WebSocket channels for order book, trades, positions, and P&L. Action Plan: Phase 1: Finalize specs (markets, fees, ticks, limits), design schemas and API contracts. Phase 2: Ledger/wallet refactor: balances, locks, fees; DB migrations and unit tests. Phase 3: Matching engine + order book: post/modify/cancel, partial fills; property tests and benchmarks. Phase 4: Real-time UI/API: WebSocket feeds, depth/last price, P&L/positions; integrate existing endpoints. Phase 5: Settlement: admin-triggered outcome, idempotent distribution, audits Best Regards, Sid

Hi, As per my understanding: Transform Laravel house betting site to P2P prediction market like Kalshi—add live order book, real-time matching engine, position unwind, market-driven pricing, partial fills, auto-settlement on event outcomes. Implementation approach: - Laravel backend: Build WebSocket-driven order book/matching via Laravel Echo/Pusher. - API/UI: Extend endpoints for buy/sell/modify/cancel; real-time P&L via Redis caching. - Settlement: Admin-triggered logic with wallet distributions, full unit tests. Queries: Existing DB schema for orders? WebSocket preference (Pusher/Reverb)? Event verification process? I will share my portfolio on your first message. Eager to discuss!
