@systematicls, totally understand why it can be easy to assume this is just "Binance + Kalshi is being manipulated". It's a reasonable instinct given how manipulation has played out elsewhere on places like Poly, but I'm positive it isn't the case here.
this critique would certainly make sense if Synth had sampled only the final 60 seconds of each 15-minute market, since that's the actual window feeding the resolution TWAP. But they didn't. Synth sampled across the full 15 minutes.
TBH if manipulation were as widespread as some suggest, these markets simply wouldn't have scaled the way they have. Retail wouldve burned out long ago, MMs would've pulled back liquidity against what 'toxic flow', and volume wouldve collapsed, which is exactly what we saw happen on Poly. Their short-term crypto markets were rife with manipulation earlier this year, and it led to a real, visible migration of users from Poly to Kalshi as a direct result (image attached). kudos to the
@SynthdataCo guys here, they were actually among the first to call this out publicly, well before it became common knowledge.
so why has Kalshi held up better? id attribute it to a few concrete design choices rather than luck:
1. a 60-second TWAP for resolution pricing (versus Poly's single snapshot)
2. KYC and surveillance that can actually ban bad actors (yes market manipulation is a crime) +
3. an aggregated oracle that weights many CEXs rather than relying on one, notably excluding Binance, whereas Poly relied on just Binance alone
none of this means prediction markets are perfect oracles of truth. theyre not. but I do think their inherently forward-looking nature adds a layer of richness to price discovery that spot prices alone don't capture.
