March Madness has Americans betting billions, and their credit scores show it | Official Website of Louis Velazquez, entrepreneur, finance guy and tech innovator

You filled out your bracket, put $50 on a parlay, and watched your team shock the tournament. March Madness has never been easier to bet on and millions of Americans are cashing in on the action.

But behind the highlight reels and the payout screenshots sits a growing financial problem that most bettors never see coming. New research from the Federal Reserve Bank of New York paints a disturbing picture of what happens to your credit after sports betting arrives in your state.

The data does not just apply to problem gamblers or heavy bettors; it shows measurable damage across entire state populations after legalization. If you live in one of the 40 states where sports betting is now legal, these findings are about your neighbors, your coworkers, and possibly you.

The New York Fed found that credit delinquencies are rising sharply

Credit delinquency rates climb by 0.3 percentage points across all borrowers in counties where sports betting becomes legal. Among adults under 40, the share with credit card payments at least 90 days overdue rose 7.9% after legalization, according to the Federal Reserve Bank of New York’s Liberty Street Economics report.

More than 30 states have legalized mobile sports betting since the Supreme Court struck down the federal ban in 2018. That expansion has generated more than half a trillion dollars in total wagers across the country, according to the New York Fed research published on March 25, 2026.

Americans are projected to wager $3.3 billion on the 2026 NCAA tournaments alone

The 2026 NCAA basketball tournaments are expected to generate $3.3 billion in legal wagers, a 50% increase over just three years, according to the American Gaming Association. New York alone generated $554.7 million in handle during the first week of the 2026 tournament, with sportsbook operators posting a record $57.6 million in gross revenue.

Average quarterly deposits at online sportsbooks reached approximately $40 per adult after three years of legalization, with growth driven more by new participants entering the market than heavier spending from existing bettors, according to the New York Fed.

Bankruptcy filings have surged 25% to 30% in states with legal online sports betting

A separate working paper by researchers at UCLA Anderson School of Management and USC Marshall School of Business produced even more alarming findings than the New York Fed report.

The odds of a personal bankruptcy filing rose 25% to 30% in states that legalized online sports betting, according to the study’s analysis of data from 4.38 million American adults.

Credit scores dropped three times as much in states that allowed online or mobile wagering compared to states that restricted betting to retail locations only. The ease of placing bets from your phone makes all the financial consequences measurably worse, the researchers concluded, as reported by the UCLA Anderson Review.

Young men in low-income communities face the steepest financial damage from sports betting

The financial harm from legalized sports betting does not land evenly across all demographics, and the data reveals a clear pattern. Young men under 45 in low-income communities experience the highest rates of bankruptcy, credit card delinquency, and reliance on debt consolidation loans, according to the UCLA and USC research.

Credit scores and credit card limits for younger low-income men decline the most sharply after legalization compared to any other group. A damaged credit score makes it harder to qualify for a mortgage, auto loan, or credit card with reasonable terms. It can also create problems when you apply for jobs, apartment leases, or car insurance coverage.

The betting damage does not stop at state borders, and neighboring states feel it too

One of the most striking findings from the New York Fed study is that the financial damage from sports betting spills across state lines. Residents of states that have not legalized betting still show rising delinquencies when they live near a state border where wagering is legal, according to the Fed’s analysis of Equifax credit data.

Bettors in states without legal options simply cross state lines or use location-spoofing workarounds to place their wagers from nearby jurisdictions. The spillover effect means that even if your state has not legalized sports betting, your financial exposure may already exist if you live close enough to a state that has.

Sports betting’s financial risks extend beyond state lines, affecting even residents in neighboring states without legalized wagering.

The national credit landscape is splitting into two tiers as some borrowers strengthen

The national average FICO credit score has dipped slightly, but the broader picture is more complicated than a single number suggests. More consumers now fall into both the highest and lowest credit score ranges, creating a widening gap between strong and struggling borrowers, according to a separate FICO report.

“What makes this particularly interesting is thatwe’re simultaneously seeing a record share of consumers demonstrating strong, consistent credit behaviors,” — Ethan Dornhelm, (Head of scores analytics at FICO).

The average VantageScore credit score sat at 701 in February 2026, essentially flat from a year earlier. But beneath that stable average, some borrowers are gradually sliding into lower credit tiers as financial pressures build, while the most creditworthy borrowers actually reduce their credit utilization.

How to protect your credit score and financial health during the March Madness season

Sports betting is not going away, and you do not need to avoid it entirely to protect your finances. But treating it like any entertainment expense means setting hard limits before you place a single wager this tournament season.

Practical steps to keep sports betting from damaging your credit profile;

Set a fixed dollar amount for your total March Madness betting budget and treat any losses as the full cost of your entertainment. Do not chase losses by depositing more money after a bad day of games, because that behavior is the single strongest predictor of financial harm.
Never fund sports bets with a credit card, a cash advance, or borrowed money of any kind from any source whatsoever. Sportsbook deposits made with credit cards count as cash advances at most issuers, and those transactions carry interest rates above 25% with no grace period.
Check your free credit report at AnnualCreditReport.com at least once per quarter to catch any signs of rising utilization or missed payments. FICO scores range from 300 to 850, and anything above 670 is generally considered good, while scores above 740 are very good.
Track your total monthly sportsbook deposits the same way you track your grocery or dining budget, because small bets add up fast. The average bettor spends roughly $700 per year after legalization, and those amounts tend to grow over time rather than remain steady.
If you notice that your betting has increased beyond what you originally planned, contact the National Council on Problem Gambling at 1-800-522-4700. Early intervention matters more than most people realize, and free confidential support is always available to you right now.

State tax revenues from betting won’t offset the consumer credit damage

States collected nearly $3 billion in sports betting tax revenue in 2024 alone, and that figure continues to grow as more states legalize and expand mobile access. New York imposes a 51% tax rate on gross gaming revenue, making it the most lucrative state market in the country by a significant margin.

But the New York Fed research raises a pointed question about whether those revenues justify the downstream costs of rising consumer credit distress.

“Most Americans have precious little margin for error when it comes to their finances, and while sports gambling can help when you win, the truth is it is far more likely to end up hurting in the long run,” Matt Schulz, chief credit analyst at LendingTree, told CNBC.

With 40 states plus Washington, D.C., now offering legal sports betting, the financial research will likely fuel legislative debates over advertising restrictions, deposit limits, and stronger consumer protections.

Your credit score is one of the most important numbers in your financial life, and protecting it during peak betting season requires the same discipline you bring to any other major financial decision.
