Kalshi’s new employer disclosure rule means the platform now wants to know where you work before you trade — but when the ad industry’s watchdog asked who Kalshi pays to promote the platform, the company refused to answer. The two announcements landed barely 24 hours apart, capping the most punishing week of regulatory pressure in the prediction market’s history.
KEY FACTS AT A GLANCE
- Employer disclosure: Required only for markets Kalshi flags as heightened insider or manipulation risk — effective immediately as of June 9, 2026
- Not routinely verified: Employment info is checked only if an investigation opens, but it can block you from certain trades
- BBB referral: The National Advertising Division referred Kalshi to the FTC and state attorneys general on June 8 — automatic once a company refuses to participate
- What NAD wanted to know: Whether Kalshi’s influencer and affiliate ads disclose that the promoters are paid
- Off the table: Kalshi says it does not list markets on war, assassination, or violence
Kalshi’s Brutal June
The employer disclosure announcement didn’t arrive in a vacuum. In the eight days before it, Kalshi absorbed a Department of Justice probe disclosure, a state lawsuit, a quiet retreat on its own trademark filings, and a formal referral to federal and state regulators. April brought what we called a legal tidal wave — June has been worse.
What the Employer Disclosure Rule Actually Requires
On June 9, Kalshi announced three market integrity measures, all effective immediately: a risk-scoring system, employment verification, and enhanced whistleblower tools. The headline change is the employment piece — before trading in markets the platform flags as sensitive, users must now tell Kalshi who they work for.
“For markets with heightened insider or manipulation risk, we now collect employment information”
— Kalshi, market integrity announcement, June 9, 2026
The goal is to identify and screen out presumptive insiders before a trade ever executes, rather than chasing suspicious wins after settlement. Which markets count as high-risk is decided by the new risk-scoring system, which rates every market across six dimensions: corporate KPI and event risk, outcome concentration, market importance, regulatory risk, non-traditional insider risk, and national security risk. In practice, that points at markets tied to corporate performance, national security, and major geopolitical events.
There’s an important catch: according to NBC News, Kalshi won’t routinely verify the employment information users submit unless an investigation is opened. But the disclosure still has teeth — some users can be blocked from specific trades purely based on where they work. Robert DeNault, Kalshi’s head of enforcement, said the measures continue the company’s push to lead federally regulated prediction markets on integrity, and the rules follow recommendations from Kalshi’s independent Surveillance Audit Committee, which will now publish quarterly reports.
Why Now: The Insider Trading Wave
The timing is no mystery. A week before the announcement, NPR revealed the DOJ is investigating George Santos for insider trading on Kalshi — the former congressman allegedly bet on his own State of the Union appearance, misled the public, and pocketed tens of thousands of dollars. And Santos is just the most famous name in a year that has already produced the first-ever Polymarket insider trading charges against an Army Green Beret who bet $400,000 on the Maduro raid he took part in, and a Google engineer’s $1.2 million “Year in Search” scheme.
Kalshi has been advertising its enforcement record alongside the new rules. The company says it opened more than 150 investigations in the first quarter, blocked over 100 potential insider trades, referred more than 20 cases to law enforcement, and issued five disciplinary actions — figures CoinDesk notes could not be independently verified. The platform’s first public insider-trading penalty, a $20,000 fine against a MrBeast editor, already hinted at how common the problem is, and suspicious trading cases have been surging across the industry.
The Other Watchdog: What the Kalshi BBB Referral Means
The day before Kalshi unveiled its transparency rules for traders, it was formally cited for refusing transparency itself. BBB National Programs’ National Advertising Division — the ad industry’s main self-regulatory body — had opened an inquiry into whether Kalshi’s social media promotions disclose its paid relationships with influencers and affiliates, as required by the FTC’s Guides Concerning the Use of Endorsements and Testimonials in Advertising. Kalshi declined to participate at all.
NAD will refer Kalshi “for review and possible enforcement action for failure to participate in the National Advertising Division (NAD) inquiry.”
— BBB National Programs, June 8, 2026
Under NAD and NARB procedures, that refusal triggers an automatic referral — there is no discretion involved. The case now goes to the FTC, relevant state attorneys general, and the social media platforms where the ads ran, all of which can act on it independently. For a company already being sued by New Mexico over sports contracts that make up the bulk of its volume — about 87% of Kalshi’s event contracts were tied to sports as of mid-May, according to SBC Americas — handing state AGs a second front is a curious choice.

What It Means for Traders
For everyday users, the practical change is a new question between you and certain markets. Most sports and entertainment contracts shouldn’t be affected, but markets touching corporate earnings, geopolitics, or national security now come with an employment form — and an answer Kalshi doesn’t like can keep you out entirely. The privacy trade-off is real: you’re handing a trading platform your employer’s name so that it can decide whether you might know too much. One industry view, from LO:TECH co-founder Tim Meggs speaking to CoinDesk, is that the sector is finally “starting to build the surveillance infrastructure to match its ambitions.”
The influencer referral cuts the other way. If the FTC or state AGs pursue it, the ads filling your feed — the streams, the picks, the “I made $5K on Kalshi this weekend” posts — may soon carry the paid-promotion labels that sportsbook ads already do. Whether the platform that now requires disclosure from its own traders can keep refusing it to everyone else is the question regulators just inherited.
FAQs
Under a rule effective June 9, 2026, markets Kalshi flags as having heightened insider or manipulation risk require traders to submit employment information before they can trade. The platform uses it to identify and screen out presumptive insiders before transactions execute.
Higher-risk markets such as those tied to corporate performance, national security, and major geopolitical events. Kalshi’s risk-scoring system rates every market on six dimensions — including corporate event risk, non-traditional insider risk, and national security risk — to decide which ones qualify.
Not routinely. According to NBC News, Kalshi only verifies workplaces if an investigation is opened. However, some users can still be blocked from specific trades based on the employer they disclose.
The BBB’s National Advertising Division was investigating whether Kalshi’s influencer and affiliate ads clearly disclose paid relationships, per FTC endorsement guidelines. Kalshi declined to participate in the inquiry, and under NAD/NARB procedures non-participation triggers an automatic referral to the FTC and state attorneys general.
The FTC and relevant state attorneys general can open reviews or enforcement actions over the advertising conduct. The social media platforms where the ads appeared are also notified and can remove non-compliant promotions.
It’s a legal gray zone. Prediction markets aren’t covered by securities insider-trading law, so recent cases have been charged under other statutes, and platforms largely self-police. Rep. Ritchie Torres has introduced a bill to ban insider trading on prediction markets outright.
KEY TAKEAWAYS
- Employer disclosure is live — trading Kalshi’s high-risk markets now starts with telling the platform who you work for, effective June 9
- It’s screening, not surveillance (yet) — info isn’t routinely verified, but it can block you from trades before they happen
- The BBB referral was automatic — refusing to engage with the NAD’s influencer-ad inquiry sent the case straight to the FTC and state attorneys general
- The contrast is the story — in 24 hours Kalshi demanded transparency from traders while declining to provide it about its own advertising
- The insider wave forced its hand — the Santos DOJ probe, a $400K Maduro-raid case, and a $1.2M Google engineer scheme made 2026 the year prediction markets had to grow up
