Would You Bet on the COVID Lab-Leak Theory? Prediction Markets Now Trade the Past

  • Each contract pays $1 or nothing, and the company's own evidence-scoring system decides which side wins.
  • It is open only outside the US for now, as the startup called Verifact Markets looks for a regulatory route to American users.

Verifact Markets, a Chicago-based startup , launched a platform yesterday (Tuesday) where users trade on whether contested claims about past events are true. Payouts depend on an evidence review run by the company, not on something that has yet to happen.

Users buy True or False contracts that pay $1 to the winning side and nothing to the losing one, the same payoff used by prediction markets.

London's trading industry is coming home!

A market settles only when the company's patent-pending framework reaches "a high level of confidence" in the evidence. Users can submit material alongside what Verifact's own systems find, according to the announcement.

Settlement has been a recurring problem for prediction markets. Polymarket contracts on a US-Iran peace deal drew more than $345 million in volume in June and then stalled over whether the agreement counted as a "permanent peace deal".

Verifact lists only claims people already disagree about, so every one of its markets begins with that kind of argument.

Who Decides the Answer

Chief Executive Rodrigo Aquino said making or spreading a claim has never been easier. "Resolving one has never been harder," he said.

Polymarket hands contested outcomes to holders of UMA tokens, and nine wallets control more than half of the tokens used in dispute votes, FinanceMagnates.com reported in June.

Kalshi, which overtook Polymarket with about 60% market share, settles under a rulebook supervised by the Commodity Futures Trading Commission (CFTC ).

At Verifact, the call stays inside the company's own system, which weighs how strongly the gathered material supports each side.

Some markets may never reach a verdict. If trading fades and no new evidence appears for a period of time, Verifact may expire the market and settle positions at a price calculated from recent qualifying trades, the company said.

In that case holders are paid out without the claim being decided.

COVID, WhatsApp and the NBA Salary Cap

Listed markets include whether COVID-19 came from a laboratory at the Wuhan Institute of Virology and whether Meta overstated WhatsApp's privacy in its "Not Even WhatsApp" campaign.

Another asks whether the Pentagon fired Stars and Stripes journalists over reporting on the USS Abraham Lincoln. During a private beta, a market on whether the LA Clippers used Kawhi Leonard's endorsement deals to get around the NBA salary cap resolved True, according to Verifact.

The company is backed by Positron Capital Management, which it describes as a multibillion-dollar family office with investments in prediction markets. Kalshi alone passed $100 billion in lifetime notional volume in June.

Verifact is open to eligible users in several jurisdictions outside the United States. It did not name them. The company said it is pursuing a regulatory path to a US launch.
