Headline, Coinbase users blast March Madness push notifications, published at 1.52 pm March 23rd,
2026. Coinbase users are complaining about receiving multiple push notifications per day,
urging them to predict sports gameplay during March Madness College basketball.
Indeed, so many complaints were reported via X that it became a trending topic yesterday.
Many customers, echoing allegations by state attorneys general in Michigan and Arizona,
described the annoying promotions as de facto advertisements to gamble on sports. Coinbase is
one of the longest continually operated Bitcoin BTC exchanges, which safeguards billions of
dollars worth of assets for customers. However, rather than focus on long-term investments like
BTC, Coinbase regularly floods its app with short-term promotions, all-or-nothing predictions,
Memcoins, leverage derivatives, and other high-risk wagers. Full-screen promotions
tempt many users into risky trades, while many customers don't see a single mention of BTC
during their entire Coinbase app experience. Indeed, the homepage of the app as of
Protos's last check featured a March Madness advertisement at the top of the home screen,
with no mention of BTC above the fold. One customer and Coinbase stockholder posted screenshots
of the basketball notifications, which arrived several times daily. This is essentially encouraging
me to gamble, he wrote, very bad for our industry. CEO Brian Armstrong responded the same
afternoon, calling it a fair point and promising customization options. However, the concession only
drew sharper criticism. Alexander Leishman, founder of BTC Exchange River, replied to Armstrong,
it's long-term very bad for our industry to be pushing sports betting. The blowback will impact
all of us. Days earlier, a Missouri researcher had posted a nearly identical complaint.
Why am I getting notifications from Coinbase about betting odds for college basketball games,
he wrote. This is just reinforcing the notion that crypto is just another gambling product,
and not an actual investment to be taken seriously. Crypto attorney Ariel Givner compared the
moment to Jules, Ryze, and Fall. Other users were more blunt. Every time I open your Dodu's app,
I'm getting bombarded with gambling notifications. One wrote, tagging Coinbase directly. Read more,
NHS exec warns that crypto trading could fuel problem gambling.
Coinbase sports event contracts. Coinbase launched prediction markets in all 50 states in
January, 2026, through a partnership with Kalshi. Users can place prediction trades on sports,
politics, and culture outcomes. Funding trades with cash or USDC. Under federal law,
these are legally event contracts, not sports bets. Coinbase has sued regulators in Connecticut,
Michigan, and Illinois who disagree. The legal distinction hasn't convinced everyone.
Nevada, Illinois, and Connecticut have all argued these contracts are functionally gambling,
while a class action lawsuit in New York alleged that Kalshi doops consumers when they are
actually gambling against the house. Illinois regulators stated plainly that athletic
competitions aren't economic instruments. Chris Christie told CNBC, if it looks like a duck
and quacks like a duck, it's a duck. It's a sports bet. Coinbase disagrees entirely,
and is suing various regulators who have likened its prediction markets to gambling.
