My favorite Kalshi value is "Climbing the steeper mountain."

As testament, a few years ago during tougher times, our team climbed a literal mountain of boulders (with @luanalopeslara on crutches!!) to get us back on track. On the climb we learned:

Time moves slower: what looks like a quick success is the result of people never taking a single day for granted.

Motivation comes from within: seeing a peak is gratifying, but you only get there by believing first.

Never give up: the only risk to not reaching the peak is to stop moving.

Better with friends: @mansourtarek_ refusing my excuses, and @liorhir walking with me when I struggled.

Don't leave the group: individual success isn't better than building something greater than the collective.

Today's raise marks new peaks, friends (maybe you 👀), challenges, and beautiful moments along the way. This journey has been the privilege of my life, and I'm grateful for each step.

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.

@PMwatchUS @oaktoebark @mattkalish I’ll try to make my point clearer. I thought I was asked about the CLOB so I responded about it. If I felt a question was asked about RFQs I would have been happy to answer as well (which someone else did). I may have interpreted it wrongly.

[rainer 🇭🇹🌹🌱 @_rainerds]

@PMwatchUS @oaktoebark @mattkalish Lol, I got a notification and can’t sleep. I think the misunderstanding is in my vernacular CLOB = orderbook.

[rainer 🇭🇹🌹🌱 @_rainerds]

@PMwatchUS @oaktoebark @mattkalish What was quoted was me responding to a question about the orderbook which has no concept of counterparty ids. Someone else did ask me about RFQs in the same thread and I responded.

[rainer 🇭🇹🌹🌱 @_rainerds]

I’m sorry I don’t see how I was dodging any question here. Matt quoted me responding to personal with something patently false (I assume out of ignorance/not on purpose) and I clarified. In the same thread another person directly asked me about RFQs and I responded to them as well. Agreed that everything is documented online as is required of us

[rainer 🇭🇹🌹🌱 @_rainerds]

@mattkalish I’ll be clearer. Kalshi Trading CANNOT see orderbook participants. They trade under the same rules as anyone else who opens an account today. I and all Kalshi Exchange employees are banned from trading

[rainer 🇭🇹🌹🌱 @_rainerds]

@Nostroah @ArchStantonGold @samschwartz71 @eightyhi @Kalshi Or if you happen to see liquidity on the book and want to take it on, all fair game

[rainer 🇭🇹🌹🌱 @_rainerds]

I was/am working, but I'll respond for you. RFQs are a tool for requesting liquidity. They aren't necessary to place trades anywhere on Kalshi. Trades at any price of your choice can be made by placing it on the book. My personal opinion is that the RFQ id is unnecessary but you can choose to avoid it if you'd like.

[rainer 🇭🇹🌹🌱 @_rainerds]

@ArchStantonGold @samschwartz71 @eightyhi @Kalshi We don’t ever expose usernames (or PII). There is an id emitted with RFQs that I’m not a fan of, but it is consistent across all users, anonymous and can be avoided by using the open orderbook directly
