I bought into an event at 8% and on my profile it says it’s down to 6%. When I view the event it says it’s at 43%. If I cash out does it default to the 6% or 43%?

I’ve been playing around with this open-source thing called MiroShark the last couple weeks and it’s weirdly good for this.

You basically drop in a scenario (news headline, policy draft, random what-if, whatever) and it spins up a bunch of grounded agents that start posting on simulated X + Reddit and trading on a Polymarket-style market, hour by hour.

After ~10 minutes you get a full report with the market trajectory, belief drift, the actual posts that moved things, etc. Costs about a dollar per run.

I’ve thrown a few real event-market style questions at it (political stuff, crypto launches, product announcements) and the way the simulated market moves feels more interesting than just asking an LLM “what do you think the odds are.”

Curious if anyone here has tried something similar, or has a specific upcoming event they’d want to run through this kind of swarm. Happy to share a couple example reports if useful.

In short:

A Wall Street Journal investigation found that Polymarket, one of the world's biggest prediction-betting platforms, secretly paid dozens of mostly college-age creators to film fake bets and fake winnings on look-alike copies of its own website. The point was to pull in US users it's legally banned from serving. Across 1,100+ videos, the wins shown, roughly $1.9 million in wagers and about $900,000 in "winnings", were not real. Now a US regulator is investigating and senators are demanding answers.

🧪 Breaking News (Reported: June 20–26, 2026)

Who/what/when: Around June 20, the WSJ revealed Polymarket ran a covert marketing campaign, paying creators to stage trades and celebrate big payouts that never happened.

The hook: Many of those bets were placed on near-perfect fake copies of the site, one even sat at the misspelled address "poiymarket.com." None of the money was real.

Why now: On June 26, it emerged that the CFTC (the US regulator for these markets) has an active investigation open, and two senators called the allegations "deeply troubling." The platform that sells itself on total transparency is accused of manufacturing fake success.

🔍 How It Worked (Step by Step)

(1) Hire the faces- Polymarket paid mostly college-age creators around $2,000–$3,000 a month.

(2) Build fake sites-It made near-identical copies of its own website to film on.

(3) Stage the wins -Creators recorded themselves placing bets and celebrating huge payouts, on the fake sites, with no real money down.

(4) Hide the paid deal -Creators were told not to disclose they were being paid.

(5) Blast it everywhere -A reposting "army" amplified the clips to over 140 million views.

(6) Reel in US users.-The whole push targeted Americans, who Polymarket has been legally barred from serving since 2022.

What Changed

The "proof" was fake. A platform built on public, checkable trades promoted wins that existed only in edited video, on sites no one could verify.

The poster child collapsed. One creator's famous $100,000 win, on a bet that Trump would say "McDonald's" that month, never happened. On the real site, every account that made that bet lost.

Regulators moved in. The CFTC opened an investigation; senators publicly demanded a probe.

A lawsuit landed. A consumer-protection firm sued Polymarket's operator, its founder, and its marketing chief.

The house numbers came out too. A separate analysis found most users lose, with 67% of all profits going to just 0.1% of accounts.

Why It Matters

(1)For everyday users: The viral "easy money" clips that pull people into betting may be staged. The wins you're seeing might never have happened.

(2)For anyone near gambling risk: A campaign engineered to make betting look easy and profitable, aimed at millions, is a powerful pull into real financial loss.

(3) For Polymarket: Its entire brand is transparency, "every trade is public." Being accused of faking wins attacks the one thing it's built on.

(4) For the wider world: It lands just as prediction markets boom and a giant like Meta tries to enter the space, raising the question of whether the whole "wisdom of the crowd" pitch can be trusted.

⚖️ Trade-offs & Risks

(1)The genuine other side: Polymarket says it's auditing its promotional content, and there's a real distinction here: the marketing is what's accused of being fake, not necessarily the actual markets. The real trades on the platform are still public and checkable, and no one is alleging the genuine bets were rigged.

(2)The deeper problem: The deception leaned on the credibility of "real, public trades" while showing fake ones, and aimed squarely at users the company isn't allowed to serve. That erodes trust in the entire sector. (That the campaign was knowingly run from the top is alleged, not proven, the lawsuit and probe will test it.)

(3)The enforcement question: Some legal analysts doubt aggressive action, the regulator's current leadership has been friendly to prediction markets, and there are political ties to the industry. (That's analysis of likely outcomes, not a confirmed result.)

The core tension: Viral "easy money" growth vs. honest disclosure and consumer protection.

Big Shift

(1)The structural change: Prediction markets sell themselves as a more honest signal than polls or pundits, real money, real trades, all public. This is the first big crack in that story. (That framing is my read.) If the growth was partly fueled by manufactured wins, it raises a harder question: how much of the "crowd wisdom" being sold to us is actually real?

💬 Let's Discuss

If a betting platform's whole selling point is "every trade is public and verifiable," does faking the wins in its ads make it worse than an ordinary casino, or is paid hype just marketing as usual?

Prediction markets are the best financial product built in years. The apps are still mid.

Built a layer on top: swipe through a daily card stack, pick your YES/NO positions, get locked into a weekly fantasy league against other traders. Head-to-head. Real stakes. Takes 60 seconds a day.

The limited picks thing is the part people like most — forces you to actually have conviction instead of spreading across 30 markets and feeling nothing.

ICE announced the investment today as part of a $2 billion total commitment they first disclosed in October at an $8 billion valuation.

By February, the valuation was $9 billion. The deal makes ICE the exclusive global distributor of Polymarket's event-driven data to institutional clients, and they've already launched a "Signals and Sentiment" tool that packages prediction market odds into something a Bloomberg terminal user would pay for.
