I watched a single sponsored post turn a slow-counting civic process into a fevered accusation. You felt the momentum: late-arriving ballots became evidence of a plot before the math finished. I wanted to know who paid to spread that doubt.
I’ll walk you through what Kalshi did, what Polymarket hasn’t said, and why a few paid posts can rewire a city’s election conversation.
On X, paid posts claimed late mail-in ballots always favor Democrats — Kalshi asked influencers to take some down
Observation: multiple X posts tied to prediction-market sponsorships framed California’s ordinary late-count patterns as proof of rigging.
Semafor reported that Kalshi quietly asked a set of paid influencers to delete posts that “sowed doubt about the integrity of the Los Angeles mayoral election.” Among the examples: embeds of market odds shared by right-wing accounts that included a paid-partnership label. The Polymarket embeds were like a match to dry tinder, and a handful of high-reach accounts turned a counting quirk into a narrative of theft.
Notice how the mail-in ballots that come in last second always end up voting Democrat
Totally a coincidence, nothing to see here https://t.co/6bYH6kvLov

The public has so little faith in California’s elections that they just assume Democrats are going to dramatically rig it with questionable ballot counting DAYS after Election Day https://t.co/yXOaY1HEUP

Kalshi told Semafor it “asked these to be taken down” because the posts violated its affiliate marketing rules. One removed post from an account with 1.7M followers reportedly asked, “Is CA cheating to get Spencer Pratt out?” and embedded a Kalshi link. You don’t need me to tell you why a 1.7M-follower endorsement makes a message go viral.
Did Kalshi pay influencers to spread election conspiracy theories?
Short answer: Kalshi acknowledges affiliate relationships and asked specific posts removed when they crossed a line; it did not, as far as public reporting shows, endorse claims of vote-tampering. Semafor’s reporting cites Kalshi requests to delete posts that violated policy. Polymarket, by contrast, hasn’t publicly confirmed removals or provided a comparable statement.
On the ground, vote tallies showed a “red mirage” — markets and commentary were racing the count
Observation: early results in the Los Angeles mayoral primary made the conservative candidate look stronger before late ballots shifted the picture.
In California, the so-called red mirage is routine: ballots counted early often favor Republicans, while mail-in and later batches skew Democratic. That pattern made Spencer Pratt look like a lock on election night; days later Nithya Raman gained on him as additional returns trickled in. The math didn’t change so much as the timeline did.
My estimate yesterday was that Raman needed to win what was left over Pratt by 12-13% .
Today, after this batch (which she won by 21%), my estimate is that she has to win what is left over Pratt by 9-10%.
So she is certainly on track.

Polymarket’s market odds diverged from the live tally: reports showed Nithya Raman rising to about a 95% chance to advance, while Spencer Pratt’s chances fell to roughly 6%. That gap between on-chain odds and the public media tally is what paid promoters exploited: they turned a counting procedure into a narrative of theft.
Why hasn’t Polymarket removed similar posts?
Polymarket has not publicly confirmed taking down the posts cited by Semafor. Politico reviewed transaction records suggesting a Polymarket executive moved at least $350,000 (€322,000) to influencers via a personal PayPal account last year and earlier this year. Gizmodo and others reached out for comment; Polymarket did not offer a clear policy statement to Semafor before publication.
On affiliate marketing, paid posts can blur data and persuasion — the oversight question grows louder
Observation: both Kalshi and Polymarket run influencer programs that funnel market links into social feeds with paid-partnership labels.
I’ve watched affiliate lines erode the distinction between observed odds and opinion. The influencer network became an echo chamber on fast-forward, amplifying suspicion faster than corrections could arrive. Kalshi says it enforces affiliate rules; Polymarket’s public silence leaves a gap that reporters and platforms are trying to fill.
There are practical steps platforms and market operators can take: clearer disclosures tied to payment records, faster takedown processes when posts promote unverified conspiracy claims, and audit trails that link promotional spend to specific messages. You should expect the companies behind these markets — and platforms like X — to be clearer about which posts are commercial and which are commentary.
Politico’s coverage and Semafor’s reporting pushed this into the public eye; Gizmodo has sought comment from Polymarket and will update as responses arrive. Kalshi’s spokesperson, Dani Lever, framed the removed posts as violations of affiliate policy. The bigger question is whether market operators and social platforms will adopt consistent rules or wait for regulators to force clarity.
If paid posts can seed doubt about an election in real time, who is responsible for policing that influence?
