Notional value is the total face value of a position, the number of contracts multiplied by the full value each one settles at if it resolves in your favour.

Notional value is the total amount a position represents at full settlement, not the amount you paid for it. On a venue where a contract settles at one dollar if the event resolves yes, the notional value of a position is simply the number of contracts you hold multiplied by that one dollar settlement value. Hold 500 contracts and the notional value is 500 dollars, whether you bought them at 30 cents or at 70 cents.
The figure matters because it describes your maximum exposure rather than your outlay. If you buy 500 yes contracts at 40 cents you pay 200 dollars, but the position can move across its full notional range as the price travels between one and ninety nine cents. Thinking in notional terms keeps you honest about how much value is actually at stake.
Notional value is distinct from cost and from profit and loss. Cost is what you paid, market value is the current price times the number of contracts, and notional value is the settlement value times the number of contracts. On a binary contract that settles at one dollar the most a buyer can lose is the cost, while a seller who is short can face a loss measured against the full notional value.
Where a venue uses a contract multiplier, the notional value scales with it. A contract quoted in points with a multiplier attached has a notional value equal to the price times the multiplier times the number of contracts. Always read the contract specifications so you know the settlement value and any multiplier before you size a position.
Traders use notional value to compare positions of different prices on a common footing and to set position sizes against a bankroll. Two positions can cost the same yet carry very different notional exposure, so the notional figure is often the more useful number when you manage risk across several markets at once.
You hold 1,000 yes contracts that each settle at one dollar, so the notional value is 1,000 dollars whatever price you paid. If you bought at 25 cents your cost was 250 dollars and your most as a buyer you can lose is that 250. A trader short the same 1,000 contracts faces a different risk profile measured against the full 1,000 dollar notional.

Knowing the notional value of a position helps you see its true scale, but it does not make the position safe, and a large notional can mean a large loss. Stake only what you can afford to lose, never to chase a loss, and never on borrowed money. If it stops feeling like a free choice, step back.

No. What you paid is your cost. Notional value is the full settlement value of the contracts you hold, which is usually larger than your outlay on a contract priced below its settlement value.
It shows the true scale of a position and your potential exposure, which helps you size trades against a bankroll and compare positions bought at different prices.
