Prediction market KOLs who actually trade: a buyer's guide after the KOL wars

What the KOL wars revealed about the channel

In October 2025 Protos described Kalshi and Polymarket paying crypto creators undisclosed sums to carry affiliate badges on X and promote the platforms, with creators ranging from a few hundred followers to a few hundred thousand. Creators announced deals with one platform and switched to the other within weeks. One sports account said its badge was removed after it asked to renegotiate an agreement it called unclear, and that it had never signed a written contract.

Protos also cited Dune data putting Kalshi's notional volume for the week of 29 September 2025 at $956M against Polymarket's $464M. The creator spend was chasing real volume, which is why the channel got expensive fast.

For a buyer the lesson is not that creators do not work for prediction markets. It is that a badge is not a conversion, a verbal deal is not a contract, and the creators who switched sides for a better number will switch again. The signals that predict conversion matter more here than in most verticals, because the audience has already seen the badges change.

The fake-win problem, and why the brief is KOLs who trade

In June 2026 the Wall Street Journal, as reported by TechSpot, found that Polymarket had paid at least ten influencers whose videos showed big wins on bets that were not real. The investigation reviewed 1,105 videos; around 70% showed a bet, and none of those bets had been placed. Some were filmed on a dummy clone of the site. One implied a six-figure win on a market that more than fifty real accounts had lost.

Separately, NPR reported that after the June 2026 Los Angeles primary, paid creators on both platforms cited shifting odds as evidence of a vote-counting plot. Kalshi had the posts taken down and now bars affiliates from questioning election integrity. Polymarket pulled back sponsorship of some creators. The posts carried a paid partnership tag in very small type, and the reported fee was up to $500 a post.

Two consequences follow for anyone booking creators now. First, audiences have been taught to discount prediction market content that looks like a win reel. Second, the content a creator can post is narrower than it was, and the platform's own affiliate terms may be stricter than the law. The creators still worth paying are the ones whose trades are real, whose losses are posted, and whose explanation of a market is the content.

That is the brief: KOLs who actually trade.

Five signals a prediction market KOL trades

The first signal is the one to insist on. A creator who trades has a record and a reason to show it. A creator who does not will offer engagement screenshots instead. The prediction market creator brief sets out what to ask for in writing.

Match the creator type to the market category

Prediction markets are several products wearing one interface. A sports bettor, a politics follower and a crypto trader open accounts for different reasons and respond to different creators.

Politics is the category where the creator rules are tightest and the reputational cost of a bad post is highest. For a platform that lists political markets, the creator brief should say what cannot be claimed about results, and the explainer review checklist should run on every post before it goes live. Budget by category and event rather than by creator tier; our prediction market influencer cost guide explains why.

The posting rules that now apply

The rules are a mix of law, platform terms and what the last year taught everyone. The brief should state them, and the contract should make them conditions of payment.

• Disclosure with the post. The FTC wants the paid relationship where the reader will see it, in plain words, not in small type at the end.
• No fabricated positions. Every screenshot or screen recording of a trade must be a real position on the creator's own account, and the brief should require the position link.
• No claims about election integrity or outcomes. Kalshi's affiliate terms now bar it, and a creator who does it on your platform will be your headline.
• Odds are prices, not predictions. A post that presents a market price as a forecast of what will happen misleads the audience and invites a complaint.
• Jurisdiction in the brief. Which markets the audience can legally access, and which product the creator is promoting in which country, written down.

Our creator disclosure examples show wording and placement that pass, by platform and format.

None of this reduces conversion for creators who trade. It removes the creators who do not.

Measure funded accounts, then trading days

The first action is a funded account on the creator's code. The second, and the one that decides renewal, is how many days that account trades in its first 30. A creator whose audience funds and trades once around an event has sold you an event. A creator whose audience is still trading three weeks later has sold you a trader.

Report per creator: funded accounts, first trades, 30-day trading days per account, category of first trade, and volume per account with the top-ten concentration shown. Event-driven categories will spike and fall; that is expected, and the comparison is between creators in the same window, not between a sports creator in finals week and a macro creator in a quiet one.

The crypto influencer ROI guide covers turning those cohorts into a return line. For a prediction market the return is usually fee revenue from attributed accounts over 90 days, and the window has to outlast the event the creator was booked around.

A hypothetical event-week wave

This example is invented. A prediction market platform books six creators for the week before a tournament final: three sports betting analysts, two general crypto accounts with large followings, one niche community account for the sport.

Day seven after the final: the two large crypto accounts produced the most clicks and 61 funded accounts between them, 70% of which never traded again after the final. The three analysts produced 148 funded accounts; at day 30, 44% had traded on at least five days, most of them in sports markets that were not the final. The niche account produced 23 funded accounts, 19 of which were still trading at day 30.

The renewal decision is the three analysts on a fee plus per-funded-account terms for the next event cycle, the niche account on a standing monthly deal, and the two large accounts released. The viewer and follower numbers would have ranked them in the opposite order.

What to bring to the first call

The categories you list and the ones you want to grow. The markets you can onboard users from, since that decides which creators are even eligible. The funded-account offer, if any. Your affiliate terms as they stand, because they will shape the brief. Any creators currently carrying your badge, with their funded-account numbers.

From that we map creator types to categories, write the posting rules into the brief and set the per-creator tracking inside the prediction market influencer marketing service. We will not book creators who cannot show a position history, whatever their reach.
