Short answer...
Conventional markets do not allow users to express the full range of their conviction. Binary outcomes (yes/no) are outdated in a lot of ways:
1. 100 or 0 outcomes (you either win or lose everything) -> bad model, completely destroys retention and promotes information asymmetry incorrectly
2. Liquidity provisioning does not work with binary outcomes in the way required to actually onboard different userbases beyond just traders -> liquidity providers are a different userbase but just as useful but don't fit into the current model of prediction markets
Those are the two main issues within conventional PMs. It's a stagnant and antiquated model.
The model I created for Isometric is a continuous curve models that allows conviction to be expressed numerically beyond just 0, 1. Ranges are traded rather than binary decisions; information asymmetry is still prevalent and is rewarded via accuracy (tighter ranges an outcome within that range, higher payouts) but not penalized. You don't win or lose ALL your money, your payout is proportional to your range market output at expiration via an LMSR engine.
With the LMSR engine, that introduces the capability for, and introduction of, for the first time, DLMM mechanics for LPing (similar to Meteora) within prediction markets via buckets -> this basically creates an AMM for prediction markets where buckets can be traded and LPed into for prediction markets for the first time ever.
This is a very rudimentary explanation and there's a lot more on the X regarding the nitty-gritty stuff like positional NFTs for lending (you are minted an NFT when opening a position that represents your range, entry, shares, etc) markets P2P/OTC trading, the incentivization of LPing on a model like this rather than conventional DLMMs like Meteora (Isometric is single-sided, near-zero IL downside risk) and a lot more.
The Isometric model works at each component because each component works. It's a bit of a catch-22, but the reason it works so well is that each piece allows for other pieces to exist in the first place.
tl;dr— conventional markets = antiquated, rudimentary; Isometric's model ushers in a completely new concept of trading via quantified conviction introducing of LPing mechanics into prediction market models.
