More than 500,000 artificial streams were culled from Spotify’s charts after a top Kalshi trader flagged suspected manipulation, turning Spotify streaming fraud into a live market-integrity problem for prediction markets.
That’s the real signal beneath the headline. A digital platform metric that looked settlement-ready was later revised by the platform itself. Spotify confirmed to Wired that it found evidence of artificial streaming in incidents flagged by trader Caleb Davies, after Malcolm Todd’s song “Earrings” surged to number one on a Spotify chart.
Davies is not a casual complainant. The Minneapolis-based IT worker told Wired he estimates he has made $1.2 million across prediction platforms, including $414,000 from Kalshi’s culture markets. He said he studies Spotify data daily to trade music-chart contracts.
“Every single morning, I’m going in, downloading the data, and updating my projections,” Davies told Wired.
Now he says he’s stepping away from chart-based markets. That’s rational. If the input data can be manipulated before settlement and corrected after settlement, the product being traded is not just a music outcome. It’s the timing and reliability of Spotify’s fraud review.

500,000 artificial streams turned a Spotify chart into a Kalshi settlement dispute
The contested event centered on “Earrings” by Malcolm Todd, which jumped to number one on a Spotify chart. Davies argued on X that the move looked like “botting,” meaning purchased or automated activity used to inflate streams.
His statistical claim was extreme:
“Looking at the dataset of Sunday to Monday changes, it was a 11.24 sigma event, or a roughly 1 in 77 octillion chance of happening randomly,” Davies wrote.
Spotify later adjusted the chart, according to Wired, removing over 500,000 artificial streams. That moved Todd’s song from first to fourth.
The timing is the core problem. Kalshi had already resolved the relevant market to award traders who selected Todd’s song. Spotify’s correction came after the market outcome had been decided.
Spotify spokesperson Laura Batey told Wired:
“All streaming services face ever-changing stream manipulation. Spotify has best-in-class detection and mitigation practices for manipulated streams, and we don’t pay out associated royalties.”
That statement confirms artificial streaming existed. It does not confirm Davies’ larger theory that prediction-market traders caused it to move a contract. Wired says Spotify did not explain the manipulation, and no one has spoken with the people or group behind it. Their motive remains unknown.
A gameable platform metric became the contract’s weak point
Event contracts need a trusted settlement input. In market infrastructure, that input is often called an oracle, the source used to decide who won. Here, the practical oracle was Spotify chart data.
That is where Spotify streaming fraud becomes more than a music-industry nuisance. Spotify can detect and correct manipulated activity on its own schedule. Prediction markets, by contrast, need finality. Traders need to know which number counts, when it counts, and whether later revisions matter.
The mismatch is obvious:
| Participant | Needs from the Spotify chart | Problem exposed by the dispute |
|---|---|---|
| Spotify | Detect and remove manipulated streams | Fraud review may take time |
| Kalshi | A clear settlement result | The chart can be revised after resolution |
| Traders | Final, auditable data | A trade can hinge on numbers later rejected |
| Polymarket | Market integrity across similar contracts | The suspected song was not even listed as an option |
Kalshi spokesperson Elisabeth Diana told Wired:
“We're in touch with Spotify and are actively investigating this matter.”
Kalshi also changed its presentation after conversations with Spotify. At Spotify’s request, Kalshi removed Spotify’s logo from markets related to the company and changed language that had suggested Spotify verified chart results.
That matters because branding and settlement wording can shape trader assumptions. If a market appears to rest on verified platform data, but the platform later says the data included artificial streams, the contract design has a gap.
$1.2 million trader, $414,000 culture-market winnings, one chart he won’t touch now
The available numbers make this episode concrete without needing to inflate it.
Verified figures from Wired:
- 500,000-plus: Artificial streams culled by Spotify from the chart.
- First to fourth: Todd’s “Earrings” after Spotify adjusted the chart.
- $1.2 million: Davies’ estimate of total winnings across prediction platforms.
- $414,000: Davies’ reported Kalshi culture-market winnings.
- 11.24 sigma: Davies’ claimed statistical anomaly for the Sunday to Monday chart move.
- 1 in 77 octillion: Davies’ claimed rough random-chance equivalent.
The missing number is just as important: Wired does not report the cost of generating the artificial streams, nor the exact profit available from the Kalshi contract. Without those figures, no one can calculate whether manipulation would have been economically rational in this specific case.
But XOOMAR’s analysis is straightforward: if a market’s liquidity is thin enough, even a modest ability to move an external metric can become valuable. The risk is not limited to whether manipulation happened here for market profit. The risk is that the contract made such a strategy conceivable.
Davies rejected one possible explanation raised by Kalshi enforcement head Robert DeNault, who suggested Kalshi traders could have been copying Polymarket activity. Davies told Wired:
“Nobody from Polymarket profited from the fraud. That’s what undermines Kalshi’s argument, because they didn’t have a Malcom Todd bracket.”
Polymarket spokesperson Annabel Walsh also pushed back:
“It’s actually not plausible since we didn’t even have Malcolm Todd as an option on this Spotify market.”
Polymarket told Wired it is reviewing the broader streaming manipulation situation but has not identified immediate manipulation so far.
Fraud risk follows the payout, not the platform category
Spotify streaming fraud already had a clear target before prediction markets entered the picture: royalties. Spotify says it does not pay royalties tied to manipulated streams.
Prediction markets add a second possible payoff path. If a chart rank can determine a contract result, then artificial streams could matter even when the streaming platform later blocks royalty payouts. That is the new market-design lesson.
Amanda Fischer, former Securities and Exchange Commission chief of staff and policy director and chief operating officer at Better Markets, framed the regulatory concern bluntly:
“The platforms are not supposed to list contracts at all, unless they make an affirmative determination that they are not readily susceptible to manipulation. It is clear that in this market, and many other markets, they are not doing that,” Fischer told Wired. “They’re obviously readily susceptible to manipulation.”
That quote does not prove Kalshi violated any rule in this instance. It does show why the dispute has moved beyond one song and one trader. If public engagement metrics are used as settlement inputs, the market operator has to assume manipulation from day one.
Todd’s role should not be overstated. Wired says he did not respond to requests for comment, and there is nothing to suggest he was anything more than an innocent bystander.
Spotify prediction markets need stricter settlement rules before serious traders return
Davies’ exit from chart-based markets is the clearest trader signal in the story.
“They've been a big gainer for me historically, but I can't play it anymore,” he told Wired.
For Kalshi and similar platforms, the fix cannot be vibes-based. If contracts depend on a manipulable platform metric, the settlement rules need to say how fraud adjustments are handled before traders put money down.
Practical guardrails would include:
- Fraud-adjustment windows: Delay settlement until Spotify or another source has had time to revise suspicious chart data.
- Clear cancellation triggers: State when confirmed artificial activity voids or reopens a market.
- Source-language discipline: Avoid implying platform verification unless the platform has agreed to it.
- Thin-market caution: Limit contracts where a relatively small metric shift could plausibly decide the result.
- Audit trails: Preserve the exact dataset used for settlement and any later revisions.
The next watch item is narrow and testable: whether Kalshi changes the rules for Spotify-linked contracts after its investigation, and whether Spotify offers any more detail on how quickly artificial streams can be detected and removed from chart calculations.
If market operators keep listing contracts tied to public digital metrics, this dispute will not be the last. The next fight may not be over whether manipulation happened. It will be over who bears the loss when the settlement number stops looking final.
