A guide to understanding prediction markets and how Prophera works
Prophera is a prediction market platform that turns questions about future events into something measurable — a live probability, shaped by the collective knowledge of everyone participating.
Instead of just reading a headline or seeing a poll, Prophera lets you engage directly with a question: What do you actually think will happen? You back your view by taking a position, and the market price reflects the crowd's best estimate of the probability at any given moment.
It's a way to think more carefully about uncertainty — and to see how your beliefs compare with everyone else's.
Prediction markets have a long history as forecasting tools. The idea is simple: if people have real stakes in being right, they'll bring their best knowledge to bear.
A YES share priced at 0.70 means the market believes there's roughly a 70% chance the event happens. As people buy and sell, that number shifts in real time.
When something relevant happens in the world — a news story, a data release, a surprise development — participants update their positions and the market price moves accordingly.
Imagine a market asking: "Will the UK inflation rate fall below 3% by December?"
The market price told a more nuanced story than any single analyst's view.
When a market resolves, the losing side's pool is distributed to everyone on the winning side, proportional to their share.
For example:
If YES resolves correctly:
The more participants there are on both sides, the more meaningful the market price becomes as a probability signal.
Prices on Prophera are determined by an automated pricing model called the LMSR (Logarithmic Market Scoring Rule). This model was designed specifically for prediction markets to ensure prices always reflect meaningful probabilities and that there's always liquidity to buy or sell.
Prices always represent a probability. A price of 0.60 means ~60% likelihood.
Buying YES shares pushes the YES price up (and NO price down) automatically.
You can always buy or sell — there's no need to find a counterparty manually.
Markets on Prophera are created and curated by the admin team to ensure every question is fair, clear, and resolvable.
A well-designed market question has four essential qualities:
This rigour is what makes Prophera's markets useful as forecasting tools — vague questions produce vague signals. Clear questions produce meaningful ones.
When a market's resolution date arrives, the admin team reviews the real-world outcome and settles the market accordingly.
One of the most interesting properties of prediction markets is what happens when many people with different information and perspectives all participate in the same question.
No single person has complete information about most events. But different people know different things — an economist might understand inflation trends, a local businessperson might notice something on the ground, a journalist might have seen an unpublished story.
When all of these perspectives are reflected in a market, the price becomes a surprisingly good summary of everything that's known. This is sometimes called the "wisdom of crowds" effect.
When you participate in a market, you're expressing a belief. Here's how to think about it.
If you think an event is more likely than the current price suggests, you can buy YES shares. If you think it's less likely, you can buy NO shares. The price you pay reflects the market's current consensus.
For example, if YES is priced at 0.30 and you believe there's actually a 60% chance the event happens, you're taking a position that the market is underestimating the probability. That's the core of how prediction markets work.
Your stake reflects your conviction. A small position means you have a view, but you're not highly confident. A larger position means you believe strongly that the market is mispriced. Neither is inherently better — it depends on how much information you actually have.
New information emerges all the time. You don't have to hold a position until resolution — you can sell your shares at any point while the market is open.
