Kalshi raised $1B at a $22B valuation led by Coatue, with participation from Morgan Stanley, Sequoia, a16z, and others. In 2018, we were two kids who loved math, markets, and debate. And we had a dream: build the next generation financial market, where we capture a broader set of questions and harness the power of the masses to price them better than Wall Street. Kalshi was born to fulfill that dream. Today, most of these questions are traded indirectly, priced through imprecise proxies or negotiated bilaterally in opaque, restricted, relationship-driven markets. But thanks to our incredible community of users who make our markets work, Kalshi has the opportunity to change that by turning historically fragmented and untradeable risk into open, liquid, and standardized markets. We’ve seen this movie before. When interest rates, currencies, commodities, and crypto moved from dark to lit markets, volume did not just migrate: access expanded, new use cases emerged, and the opportunity grew by orders of magnitude. Today, Kalshi represents over 90% of US prediction market volume and the majority of activity globally, with annualized volume growing to $178B over the past 6 months. What started as retail is quickly becoming institutional — hedge funds, asset managers, prop firms, and insurers are beginning to trade, provide liquidity, and hedge real-world risk directly. The scope and scale of prediction markets are just beginning to take shape. We’re using this new capital to accelerate the institutional adoption underway — unlocking trillions in capital to facilitate active trading and risk management. Prediction markets are moving from early adoption to core financial infrastructure. This is just the beginning.

It's wild to me that anyone would choose to build a startup in Eswatini! cool story... A white guy from New York got interested in it after playing Geoguessr as a tween, started a company there and raised $7.3M! I've been there. It's a crazy place! Random facts: -last absolute monarchy in Africa -King has 15+ wives. Every year there is a festival called Umhlanga where he can choose a new one - 40,000 unmarried women dance bare-breasted in front of the king and he can choose a new fiancee from the crowd, and he marries her after she gets pregnant. Several were 16-18 when chosen -Population: ~1.25M people, 26% of whom have HIV :(. -GDP is ~$5B, ~1 week of NVidia revenue -surrounded by South Africa (I drove there from Johannesburg on my way to a game preserve) He dropped out of Berkeley after freshman year, launched the app in Eswatini, then moved the whole thing to Lagos (which makes a LOT more sense) to build an African super app with food delivery as a wedge product.

Excited to announce that Swoop has raised $7.3M from @LongJourneyVC ,@variantfund, @VersionOneVC, @Soma_Capital, @dunevc, Base Capital, @nickymontanaa, and others to build Africa's super-app! We launched as a food delivery service in Eswatini and became the country's largest ecommerce platform with 22K+ users. Now, we're launching food delivery in Lagos, with payments and other verticals coming later this year.

I'm now a Thiel Fellow! Growing up in NYC, I became obsessed with geography and later Africa. I started my first company in Africa at 15. Now, I've moved to Nigeria to build Africa's super-app. I wake up excited to work tirelessly on a single thing. More fun than college.

I guess I'm a Thiel Fellow now?! I'm building AI models at @AntifraudCo to catch fraudsters who defraud the American taxpayers. We're qui tam laws to sue the fraudsters directly, and keep 15-30% of the recovery. Today, some fraudster's day got a bit worse... (also we're hiring!)

Whilst my testosterone is currently top 2% (937 ng/dL), my estradiol is also higher than I’d like. So, I’m experimenting with two supplements to lower estradiol: + DIM – 100mg daily + Calcium d-glucarate – 1,000mg daily I’ll do this for a month, and then re-test my levels with @superpower.
