After a week of geopolitical shock, prediction markets have returned to routine.Trading continues, positions are opened and closed, and the machinery keeps running. On the surface, it looks like business as usual. But a few developments were hard to miss.Platforms have started testing price competition, while banks and regulators are raising more questions about insider trading — a sign they are beginning to take the risks of this market more seriously.Here’s what mattered this week.What Moved Prediction Markets This WeekPricing Starts to MatterOne of the more practical shifts this week came from pricing.MEXC introduced zero-fee trading, a model familiar from crypto and derivatives, showing platforms are now competing more directly for trading flow. shift changes the focus. When pricing becomes part of the competition, traders begin to compare execution, liquidity, and product quality — not just access.Rules Are No Longer TheoreticalBanks are beginning to apply insider trading frameworks to prediction markets, treating them as an extension of existing financial activity.Enforcement is moving in parallel. Kalshi is facing charges in Arizona over alleged unlicensed gambling activity, highlighting how differently these markets can be interpreted depending on jurisdiction.Prediction markets are being tested against the same legal frameworks as everything else.Kalshi’s CEO called the Arizona charges “a clear overreach,” framing the case as a broader fight over federal versus state authority.The rule of law applies to everyone - including state governments.The Arizona Attorney General’s charges are baseless and a clear overreach. It’s gamesmanship from a politician who’s up for reelection.The charges claim that putting money on “a contingent future event or… https://t.co/TU4I8HV1CT— Tarek Mansour (@mansourtarek_) March 18, 2026Liquidity Concentrates, Institutions HesitatePolymarket now accounts for roughly 55% of global prediction market activity, with geopolitical events continuing to drive volume.The platform also signed a partnership with Major League Baseball, giving it access to official data for event-based contracts — a step toward more structured inputs.However, strong liquidity and high-profile partnerships have not yet translated into institutional participation. Reports suggest funds are actively monitoring the space but are not trading.The reasons are familiar: regulatory uncertainty, uneven liquidity, and unresolved questions about how these contracts should be classified.For now, prediction markets are visible — but not yet widely used by institutional investors.Quote of the WeekAfter a period of lawsuits and uncertainty, the Commodity Futures Trading Commission is starting to define its position more clearly.The agency released long-awaited guidance and opened a rule-making process, signalling that prediction markets are now firmly on its agenda.Prediction markets are one of the most exciting innovations in financial markets.

That’s how much state regulators say they are losing in sports betting tax revenue as prediction markets operate outside existing licensing frameworks.Authorities in eleven U.S. states have issued cease-and-desist orders against prediction market platforms, arguing they effectively function as unlicensed sportsbooks.The Friction of the WeekIf prediction markets can’t be stopped, they are likely to be steered.That seems to be the logic emerging on the regulatory side. The Commodity Futures Trading Commission has begun clarifying how these markets should operate, releasing guidance and opening a formal rule-making process.At the same time, state regulators are taking a different approach — issuing cease-and-desist orders and treating the same activity as unlicensed gambling.The result is a split system. Until that gap closes, the market will keep operating in both worlds at once.Bottom LineThis week reinforced an ongoing trend.
