Kalshi, an online trading startup letting users bet on “yes/no” questions about future events, raises $30M from Sequoia and others ahead of planned March launch
This is the origin checkpoint in Kalshi's arc: a pre-launch yes/no event-contracts startup taking its first institutional money. Sequoia's early check and Chuck Schwab's name-brand backing were the seed of what the coverage now shows as a capital flywheel — from this round to a $300M+ Series D at a $5B valuation with expansion to 140 countries, then a $1B raise at $22B, and now advanced talks for $750M+ co-led by Sequoia again at a $40B valuation.
The through-line is Sequoia doubling down across the entire curve, while reported annualized revenue climbed from $2B+ in June with informal IPO talks already underway toward $4B by July. What launched in March 2021 as an experiment in regulated event trading has become one of the fastest-scaling consumer financial platforms on record.
First-order effects
Kalshi enters its March launch with institutional validation that most pre-revenue exchanges never get — Sequoia's involvement signals to later-stage funds that event contracts are an investable category, which is exactly how the follow-on rounds materialized.
Retail traders get a regulated venue for binary event bets at launch, establishing the product surface — yes/no contracts on real-world outcomes — that every subsequent funding round has priced.
Second-order effects
Rival platforms like Polymarket respond by pushing distribution hard enough that both companies end up partnering with social media accounts posing as breaking-news reporters — growth tactics that invite the CFTC attention reflected in the sports-bets probe and Kalshi referring 32 possible insider traders.
As volume scales, compliance becomes a competitive moat: the exchange that can self-police insider activity keeps its regulatory license to operate the markets competitors can't.
Third-order effects
If the pattern holds, event-contract trading consolidates around one or two regulated platforms with exchange-scale balance sheets — the same structure as traditional derivatives markets, where liquidity begets liquidity and early regulatory goodwill compounds into dominance.
The trajectory from a $30M seed-adjacent round to $40B-valuation talks in roughly five years points toward prediction markets being absorbed into mainstream finance, with an eventual IPO converting event contracts from novelty to standard asset class.
The trend: Prediction markets are platformizing into mainstream financial infrastructure, with venture capital compounding behind whichever exchange secures regulatory legitimacy first.

Proud & excited for you guys -Tarek, Luana & rest of the @kalshi_official team! It's been a thriller & just getting started! @Tarrouka7 https://twitter.com/...
Reminder that real-money prediction markets came from academic research, originally @caltech c 1980s information revelation #experimentaleconomics then scaled at U Iowa https://iemweb.biz.uiowa.edu/ .... New sites are great but don't forget who invented them https://twitter.com/.…

Congrats to @kalshi_official on their $30M Series A! Through its CFTC regulated exchange, Kalshi (YC W19) is creating an entirely new way to hedge risk and trade on your opinion. https://www.wsj.com/...
We need more prediction markets. Excited to watch @kalshi_official, which goes live this March and allows investors to bet on yes / no questions. Approved by Commodity Futures Trading Commission (CFTC) in Nov to run a derivatives exchange. https://www.wsj.com/...
A real deal prediction market coming. Hopefully no bet limits and low trading costs. And contrary to this reporting I hope they DO get into elections https://www.wsj.com/...
1/ Congrats to @Alfred_Lin of @Sequoia on leading a bold $30M pre-launch investment in @Kalshi_official. Kalshi is building an epochal business: a new financial exchange for trading on event outcomes. 🚀 (1 of 2) https://twitter.com/...
very exciting—has potential to provide better predictions on more questions than existing forecasting sites like GJOpen and Metaculus. And if it's avoiding politics, it needn't face the distortionary restrictions on Predictit https://www.wsj.com/...
“It is unlikely that Kalshi would list contracts on election outcomes because in 2012 the CFTC blocked an effort to list political-event contracts, saying they involved gaming and weren't in the public interest.” https://twitter.com/...
