propSPACE Overview
propSPACE is a free fantasy trading competition that runs on the functionSPACE protocol. It lets you draft soccer players, set custom lines or ranges on their expected fantasy points, and compete for real USDC prizes using a reset $1,000 play money bankroll each round.
The competition ran during the 2026 World Cup knockout stages. Each round, you pick one forward, one midfielder, and one defender from the available fixtures. You then adjust a line on each player's projected fantasy points or draw a range and choose inside or outside. The multiplier updates live based on how far you deviate from the crowd projection. Closer to consensus means safer, lower returns. Bigger deviations mean higher potential payouts. Your trades stay private until the round closes, and the leaderboard ranks net bankroll profit after settlement.
What sets propSPACE apart is the payoff structure. Traditional sportsbooks hand you a fixed over-under line. Standard fantasy platforms force you into binary win-loss outcomes. propSPACE lets you design your own payoff shape against crowd projections and settle against actual fantasy scores. You can express a tight confidence interval, a wide safety net, or a precision call. All of these shapes trade against the same shared liquidity pool, so capital stays efficient instead of fragmenting across separate markets.
This competition is built for sports and fantasy traders who want more expressive tools than fixed lines offer. If you have ever held a nuanced view, like a player landing in a specific point range, and could not express it on a standard platform, this format solves that problem. It also appeals to anyone evaluating new market designs that treat conviction as a continuous asset rather than a discrete bet.
The $1,000 fresh bankroll each round keeps the playing field level. Strong performance in one stage does not carry forward as an advantage. Weekly prizes of $1,000 USDC went to top performers from the Round of 32 through the semifinals, and a $2,500 grand prize rewarded the best cumulative run. The total pool reached $6,500 USDC, later expanded with partner support to around $10,000.
The underlying engine remains available for other applications through a developer SDK. The @functionspace/core package lets builders design any payoff in a single call and embed continuous markets into their own products. Community projects already include narrative index vaults, market relationship graphs, and calibration tools. This makes the protocol a reusable primitive for prediction products, research tools, media experiences, and structured products.
If you want to participate, the entry process is simple. Sign up free at propspace.fun, receive your virtual bankroll, select your three players, set your lines or ranges, and stake your desired amount. Positions lock at kickoff. After settlement, review your net return and check the private leaderboard. Since the World Cup competition ended, the same mechanics remain available through other applications built on the functionSPACE engine.
propSPACE Key features
-
Draft your squad
Users pick one forward, one midfielder, and one defender each round. They receive a fresh $1,000 play money bankroll to fund these picks.
-
Set custom lines
Users move the line on a player's expected points to call over or under. The multiplier changes in real time based on the distance from the crowd projection.
-
Predict point ranges
Users draw lower and upper bounds around a player's expected points. Tighter ranges return higher multipliers and wider ranges offer more safety.
-
Keep positions private
The system hides squads and trades from other participants until the market settles. This rule prevents herd behavior during the round.
-
Reset bankroll each round
The protocol resets balances at the start of every knockout stage. One strong round does not give a player an advantage in the next stage.
-
Trade one shared pool
Users trade all custom lines and ranges against the same market state. This design keeps all the liquidity in one place instead of separating it by product type.
-
Resolve outcomes with capital
Participants bond capital to assert or challenge the final numerical value. The protocol slashes incorrect claims and rewards accurate assertions.
-
Build with the SDK
Builders use the core software package to design any payoff in a single call. Developers can add these continuous markets directly into their own apps.

Pros
- You can draw custom payoff shapes like tight ranges instead of picking from fixed over under lines.
- All payoff types share one liquidity pool so capital is not split across separate markets.
- Your trades stay private until the round closes, which prevents copy trading.
- Every knockout round gives you a fresh $1,000 bankroll so no one carries an advantage from prior rounds.
- The competition is free to enter and pays out real USDC prizes to top performers.
- The open SDK lets developers embed the same continuous market engine into their own applications.
- An adversarial resolution layer uses bonded capital to settle outcomes rather than depending on external oracles alone.
- The project published results and winner names publicly with partners like Polysights co-sponsoring the prize pool.
Cons
- The competition runs only during specific sports events.
- Full on-chain deployment is not finished yet.
- Users must learn continuous payoff concepts before they can trade.
- Prize pools stay small compared to larger prediction platforms.
- Documentation and tooling are still rough around the edges.
- Participants cannot win money outside the fixed prize structure.
- Multi-chain support is still in progress.
Our verdict
propSPACE let users draft soccer players and set custom lines or ranges on fantasy points during the 2026 World Cup knockouts, with a reset $1,000 play-money bankroll each round and real USDC prizes for top performers. The continuous payoff system from the underlying functionSPACE protocol is the real draw, letting you express views like tight scoring ranges that a standard sportsbook cannot offer. The competition runs only during specific sporting events, the prize pool of roughly $10,000 USDC is small compared to larger platforms, and the payoff concepts require some learning if you are used to fixed lines. Sports and fantasy traders who want more precision than over/under bets should try it, and developers should explore the open-source SDK to embed the same continuous market engine in their own products. The project is early and the multi-chain roadmap is incomplete, but the World Cup run delivered working software and transparent prize payouts.
Is propSPACE safe & legit?
functionSPACE, a Melbourne-based team with experience at Banxa, Sky, and Nethermind, built propSPACE. The project raised a $1.25 million pre-seed led by Maven 11, and partners like Polysights co-sponsored the prize pool. No reports of unpaid prizes or operational failures surfaced after the competition closed, and users traded with play money, so the only risk was time.

We should see event contracts as a bet on an end state i.e. who wins, or where the number lands at resolution.
In between, the market's posting prices as information arrives, and in most PM's you can trade it the along the way.
Leverage ties you to the path.... your liquidation price is set against the mark which jumps every time new information lands.
You were right about the end state and got taken out by the path.
So leverage in these markets asks you to be right twice, once about the outcome and once about the path the market takes to get there.
Leverage is a useful and probably necessary feature for building deeper markets.
One lens is that people asking for leverage want more exposure to being right on outcome i.e. a bigger payout relative to the funds they're putting at risk.
We get this property inherently on @functionspaceHQ markets as there's a native way to express something similar through a tighter range - i.e. precision.
Rather than increasing your exposure to a broad outcome through borrowed capital, you can narrow the range of outcomes you're willing to bet on.
There's no liquidation price. Your payoff at resolution depends on where the outcome lands, independent of the path prices took to get there.
Both forms of exposure have a place in prediction markets. Leverage makes the path itself part of the trade. Precision lets you express a more concentrated belief about the destination.
Both can produce higher risk and higher returns, but they're fundamentally different trades.
I think there's something interesting about being able to dial up your risk by being more specific about that end state.- 2 replies

Key takeaways from the Thought Leader Summit hosted by @Maven11Capital and co.
• We’re early.
• Are we all competing for the same customers? No. The pie is huge, and PMs are still focused on net growth. Almost any event can have a market. Liquidity will keep growing.
• Major unlock for institutions: how do we free up capital from full collateralization?
• Permissionless builder codes show where PMs can go as liquid market layers. Think Phantom x Hyperliquid.
No where but up.
