Prediction markets price one event at a time; most people want to know whether the Middle East is getting more stable. Alan Wu argues for an index layer - published weights over a basket of contracts - so the reading becomes a persistent, inspectable time series instead of a headline. Adjacent's BLUE and RED indices and Kalshi's American Power Index already disagree on the same markets, transparently. The VIX took eleven years to become tradable; the information value came first.
Kalshi, Polymarket and a trial-forecasting pilot called Endpoint Arena now let the public bet on clinical readouts and FDA approvals. Kalshi's stated case, that markets would close the "two-tier information system" between industry and everyone else, names a real problem. Wershba grants the asymmetry is genuine, then dismantles the fix: platforms can bar insiders but cannot say who actually bets, show volume rather than bettor counts, and would have sponsors and patients reading those prices as evidence.
Argues that onchain prediction market betting profiles reveal deeper insights about individuals than traditional resumes. With structured data on specific questions, resolution criteria, and outcomes, a trader's history shows how they price information and manage risk — suggesting Polymarket and Kalshi profiles may eventually appear on job applications and investor decks.
Prediction markets make information legible in a way stocks and options do not. When someone bets big on an attack on Maduro, everyone immediately knows what the bet is about, unlike a stock price spike that could mean anything. Andrew Courtney argues this legibility is a feature even when it surfaces uncomfortable national security implications.
