Kalshi launched US sports betting by self-certifying — and hired the law's author

In July 2010, Senator Blanche Lincoln, chair of the Agriculture Committee and a primary author of Dodd-Frank Title VII, warned on the Senate floor that prediction markets could evade gambling laws with 'event contracts' on the Super Bowl or Kentucky Derby — contracts 'used solely for gambling' that 'would not serve any real commercial purpose.' The law gave the CFTC authority to ban such contracts in the public interest, but Congress left the ultimate decision to the executive branch rather than writing a ban into the statute. That design choice is the door Kalshi later walked through.

CFTC Rule 40.11 (2011) banned gaming event contracts, citing Lincoln's words. Review procedures let markets self-certify contracts and trade before the agency even reviews. Crypto.com launched sports contracts in December 2024, unblocked; a Kalshi official told Ars that cleared the path. Kalshi launched on 23 January 2025, three days after the inauguration: 'The Golden Age of markets is here.' Law professor Ilya Beylin: the Biden CFTC considered them prohibited, counsel understood, and the second Trump administration 'radically changed' course, halting enforcement of the un-repealed rule.

Then it hired the record. Lincoln's firm has received $480,000 from Kalshi since 2024. Her August 2024 letter still matched her 2010 view (sports lack 'significant economic consequences'), but once the product existed she urged the CFTC to allow sports-event contracts. The Trump CFTC let them flourish nationwide without repealing Rule 40.11; its June 2026 rewrite proposal, Beylin argues, skipped weighing gambling harms. Lincoln's 2010 comments are still quoted against the industry — a federal judge cited them as proof of intent — and suits in about 20 states head toward the Supreme Court.

Kalshi's public defence is structural: 'Since Kalshi works like the stock market rather than a casino, it's regulated by the CFTC and federal law… we're subject to federal—not state—laws.' It calls opposition a 'gaming cartel' protecting its monopoly; Donald Trump Jr. advises both Kalshi and Polymarket, and in March 2026 he told Republican attorneys general to back off prediction markets. State officials have not backed down.

The ban was discretionary, not statutory: self-certify the contracts, launch before any review, then hire the senator who wrote the law — and her own record flips sides.

Congress left the sports-ban decision to the regulator, so the cheapest lever was the enforcer, not a new statute — permission by default beat asking for it.

Self-certification converted the CFTC's review window into a launch window: trade first, review never.

Hiring the provision's author turned the industry's most-cited piece of legislative history into paid advocacy; her letters show the flip tracked the client's product launch.

No law needed changing: an un-repealed rule, an un-enforced rule, and a former insider were enough.

When a rule's fate depends on who enforces it, timing is legal strategy: structure the launch so the default is permission, then persuade the enforcer — ideally with the rule's own author as advocate.

Kalshi's parallel claim — that states cannot touch its federally regulated contracts — is faring badly: appeals courts split 2–1 against it by late September 2026 (win at the Third Circuit, losses at the Ninth and Sixth), and New Jersey has asked the Supreme Court to settle the question. The Trump CFTC's proposed rewrite of Rule 40.11 remains pending and un-finalised. Lincoln's 2010 floor remarks remain the standard citation for states and tribes arguing Congress meant to prohibit, not enable, sports wagering on event contracts.
