Polymarket Asked To Work With Us. We Exposed Their Scam Instead.
Polymarket and Kalshi pitch prediction markets as democratized finance that empowers working people, but investigation reveals they are primarily gambling platforms with structural insider-trading problems, poor accuracy, and a business model that extracts money from economically anxious users while dodging state gambling regulations. ---
Key Concepts
| Concept | Definition |
|---|---|
| Prediction market | A platform where users trade on yes/no outcomes of real-world events; current market price is treated as the probability of that event occurring |
| Liquidity / wisdom of crowds | The theory that large numbers of financially-incentivized participants produce more accurate predictions than individual experts |
| Insider trading (in prediction markets) | Unlike traditional finance, prediction market theory *requires* insiders to trade in order to push prices toward truth — creating an inherent fairness problem |
| Event contracts | Industry term for bets; used deliberately to frame gambling as investing and avoid state gambling regulations |
| CFTC vs. state gambling commissions | Federal vs. state regulatory jurisdiction — federal oversight means no state taxes, no licensing fees, and no mandatory problem-gambling protections |
Notes
What Prediction Markets Claim to Be
- Aggregate the "wisdom of crowds" to produce more accurate forecasts than any single expert
- No house: platforms only facilitate transactions, don't take a side
- Democratization of finance: anyone can monetize their knowledge
- Framed as investments, hedging tools, and the "future of news"
The Insider Trading Problem
- Accurate prediction markets *depend* on insiders trading — that's how prices move toward the truth
- Dr. Robin Hansen (widely cited as the godfather of modern prediction markets): "Please insider trading. That's just not really an issue for prediction markets."
- Government action markets are structurally rigged: officials know outcomes before the public
- Enforcement is essentially impossible
- Tens to hundreds of thousands of potential insiders across all markets
- Can't track informal tip chains (e.g., a Spotify employee telling a friend)
- Senator Chris Murphy: defining who counts as an insider in global-event markets is "fruitless"
- Example: man sat outside Super Bowl rehearsal with a listening device to time the national anthem length before betting — is he an insider?
- Traditional financial markets haven't solved insider trading after decades; no reason to believe tech startups have
Accuracy Claims vs. Reality
- Polymarket CEO appeared on *60 Minutes* claiming victory for predicting the 2024 election
- Vanderbilt University study on 2024 election prediction markets:
- 93% of markets predicted better than chance overall
- Accuracy dropped to **78% on Kalshi** and **67% on Polymarket**
- Polymarket's markets were barely better than a coin flip
- February jobs report: markets forecast +60,000 jobs; actual result was down — a delta of ~150,000 jobs
Who Actually Wins
- 0.04% of traders capture nearly ~70% of profits
- Casual traders ("retail") primarily donate liquidity that insiders and professionals collect
- Reddit examples of typical user outcomes: losing $25,000, betting rent money, down $4,000 hoping discipline will fix it
It's Mostly Just Gambling
- Kalshi: **85–90% of volume is sports betting**
- Polymarket: ~40% sports, 60% other — but the "other" includes betting on Bitcoin price every 15 minutes or who the next Ayatollah of Iran will be
- Kalshi ran an ad claiming "sports betting is legal in all 50 states" — it is not
- Kalshi CEO promoted a $1B March Madness bracket prize with: *"90 minutes left to attempt generational wealth"* — at a time when Americans are making record early 401(k) withdrawals
- Kalshi briefly ran a campus ambassador program targeting college students; shut it down for bad PR
- Sometimes Kalshi itself is on the other side of the contract — meaning there *is* a house
Regulatory Arbitrage
- If classified as gambling (state level): ~51% tax in New York, licensing fees in every state, mandatory problem-gambling protections
- If classified as event contracts (CFTC, federal): none of the above
- CFTC chairman publicly defended prediction markets and threatened to sue challengers
- **Donald Trump Jr. is a strategic adviser to both Kalshi and Polymarket**
- Kalshi is now being sued by over a dozen states claiming it is gambling under state law
Public Health Concerns
- Experts, traders, and journalists consistently describe a **gambling public health crisis**, hitting young men especially hard
- Prediction markets lower the participation age to 18 (vs. 21 for casinos)
- The casino is always accessible — no trip to a bookie or casino required
- Platforms are designed for retention and cross-selling, not user welfare
Marketing & PR Strategy
- Companies avoid the word "betting" in ads
- Polymarket ran a free grocery store in NYC — a PR stunt targeting working-class optics
- Both companies have built networks of paid influencers; specifically target young female influencers to expand demographics
- Courting politicians from both parties to open doors in Washington
- Reached out to More Perfect Union to integrate their odds into reporting
Actionable Takeaways
- Treat prediction market platforms as gambling products, not investment or information tools, when assessing personal financial risk
- When evaluating accuracy claims, ask for base-rate comparisons — 67% accuracy on binary outcomes is close to a coin flip
- Advocate for state-level gambling regulation of prediction markets to require consumer protections, problem-gambling resources, and fair taxation
- Be skeptical of influencer or media partnerships with these platforms — they are part of a deliberate PR strategy, not editorial endorsement
