A pair of bipartisan senators on Wednesday said they’re keeping their push to ban sports prediction market contracts, despite Kalshi and Polymarket announcing new insider-trading restrictions on their platforms.
“It’s got to be more than an aspirational statement by these companies,” Sen. Adam Schiff, D-Calif., told CNBC’s “Squawk Box” when asked about those platforms’ self-imposed new rules.
Kalshi on Monday said it would preemptively block politicians, athletes and “other relevant people” from betting on their own campaigns or sporting events.
The same day, Polymarket announced it would impose its own guardrails to address insider trading and market manipulation.
The new restrictions came as Schiff and Sen. John Curtis, R-Utah, introduced legislation that would give states, rather than federal regulators, control over sports betting and casino-style games.
The bill would prohibit Commodity Futures Trading Commission-registered entities from listing any such prediction contract.
In a joint CNBC interview Wednesday morning, the senators said the companies’ efforts to police themselves are insufficient.
“I don’t think it’s enough,” Schiff said. “It’s one thing to say, ‘This is our policy.’ It’s another actually to put into place the steps to make sure it’s not happening on those platforms.”
Curtis has said his bill with Schiff, the “Prediction Markets are Gambling Act,” is about “keeping speculative financial products out of spaces where they don’t belong.”
“You have to ask, ‘What could go wrong?'” he said on CNBC. “Imagine betting on a high school athlete getting hurt the day of a high school game … You can see how wrong that could go.”
Schiff warned about the potential for “vast amounts of insider trading” that can’t be addressed under current regulations. He pointed to recent reports that some bettors have amassed significant sums predicting events in the Iran war with extremely high accuracy.
“That’s heavily suggestive of insider trading, and when it could be done using blockchain, there is no way to really regulate that, at least it’s not being regulated today,” he said.
Prediction markets, which allow users to quickly and easily wager on nearly anything, have become vastly more popular and accessible in recent years. That popularity is leading to increasing criticism across the political spectrum.
“Pervasive gambling is not good for society,” Rep. Alexandria Ocasio-Cortez, D-N.Y., said last week in response to Polymarket being made the exclusive prediction market exchange partner for Major League Baseball.
At the same time, the financial impacts of widespread betting are coming under increased scrutiny. Economists from the Federal Reserve Bank of New York said in a report Wednesday morning that sports betting “can have dramatic implications for household financial stability.”
“Even though the share of people taking up sports betting after legalization is small (roughly 3 percent of the population), overall credit delinquency rises by about 0.3 percentage points,” the Fed researchers said.
While any legislation faces a difficult path in Congress, Schiff and Curtis expressed optimism that their bill has enough bipartisan support to clear the House and Senate.
“I think this is one of those areas where we agree on so much more than we disagree, and I think those areas of disagreement are getting narrower and narrower,” Curtis said.
