Kalshi's prediction market platform buckled under Saturday's college football betting surge, leaving nearly half its users unable to place bets or see account balances. The outage comes just a week after the company raised $300 million at a $5 billion valuation, raising questions about infrastructure scaling at one of fintech's hottest startups.
Kalshi's prediction market platform hit a wall during Saturday's college football action, with close to half its user base locked out of betting when they needed it most. The outage struck during peak weekend trading hours, leaving frustrated bettors unable to place orders or even check their account balances.
The timing couldn't be worse for the $5 billion startup. Just over a week ago, Kalshi announced a massive $300 million Series D funding round that more than doubled its valuation from $2 billion in June. The round was co-led by heavyweight VCs Andreessen Horowitz and Sequoia Capital, with backing from Paradigm, Coinbase Ventures, and Google's CapitalG.
Users took to X (formerly Twitter) to vent their frustration, sharing screenshots of frozen betting screens and unprocessed orders. When CNBC tried accessing the site, they were greeted with just a spinning green K logo for over 20 minutes - hardly the seamless experience you'd expect from a company valued at unicorn levels.
"The Exchange is experiencing temporary delays," read an apology message Kalshi sent to affected users, obtained by CNBC. "Balances and positions may not be accurately reflected at this time." For a platform built on real-time event betting, that's essentially a worst-case scenario.
Kalshi's spokesperson tried damage control, denying there was a full "outage" and insisting the exchange "never stopped functioning properly." But the company did admit to "glitches and delays on our web and app product" affecting less than half the user base. They emphasized that clearing, advanced trading, and institutional trading weren't impacted - a telling distinction that suggests retail users bore the brunt of the technical issues.
The incident exposes a classic scaling challenge that's plagued fintech companies as they grow. College football Saturdays represent some of Kalshi's highest-volume trading periods, with users betting on everything from game outcomes to individual player performances. Founded in 2018, the platform has differentiated itself by allowing users to trade on real-world events beyond sports - from political outcomes to whether certain celebrities will get pardoned by President Trump.
This isn't just a customer service nightmare; it's a business continuity crisis. Prediction markets thrive on trust and timing. When users can't place time-sensitive bets during major sporting events, they don't just get frustrated - they start looking at competitors like PredictIt or traditional sportsbooks.
