About Book Of Faith
Another bettor noted that gambling debts fractured personal relationships: “Sports betting ruined my six years of friendship because I couldn’t pay back the borrowed loan from my friend. He stopped talking to me.”
Americans wagered nearly $167 billion on sports in 2025 through regulated sportsbooks, an 11% increase year-over-year, according to data from the American Gaming Association (AGA).
The blurring line between financial investing and gambling has been accelerated by the rise of prediction markets—exchanges offering event contracts that are federally regulated as financial derivatives. U.S. News found that over 40% of active sports bettors now also participate in sports prediction markets.

Jefferies described market makers as the ecosystem’s “liquidity backbone”. They post executable bids and offers, manage inventory and provide prices when customer activity is heavily weighted to one side.
The analysts estimated that an operator capturing a one-cent spread and managing its exposure successfully could generate net economics of approximately $1.69 on a $100 trade. Returns are not guaranteed: adverse price movements and unresolved inventory can offset or exceed income from spreads, rebates and liquidity incentives.
The operational infrastructure available to these new firms, however, remains underdeveloped. Gonzalez contrasts prediction markets with equities, where trading businesses can use prime brokers, clearinghouses and standardised systems such as FIX.

Polymarket and other prediction markets that ventured into sports trading last year maintain that they’re financial platforms governed by federal law.
The Commodity Futures Trading Commission (CFTC) agrees, continuing to defend its claimed “exclusive jurisdiction” over sports prediction markets in federal and state courts across the nation.
The legal wrangling extends to Michigan, where Attorney General Dana Nessel has rejected Polymarket and the CFTC’s arguments that the Michigan Gaming Control Board has no regulatory authority over prediction markets, even the ones allowing traders to buy and sell shares of sports outcomes.
