Y Combinator

YC is for founders, by founders. Applications for Fall 2026 close on July 27: ycombinator.com/apply

Today, we launched GPU compute forward curves derived from our prediction market prices. Forward curves are now available on Nvidia B200. H200, and A100 chips. Forward curves track implied future prices. They are how mature commodity markets form expectations, allocate capital, and manage risk. Energy, interest rates/SOFR, FX, metals, and agricultural markets all rely on market-implied forward prices. Despite becoming one of the key inputs in the global economy, compute has lacked that market-derived infrastructure. Compute right now is where oil was before NYMEX — traded only via OTC deals, just like oil used to trade OTC between producers and refiners. As compute becomes as fundamental to the economy as energy, the industry will need a similar derivative market to promote efficient price discovery. Prediction markets are uniquely suited to this problem. Compute is not one uniform commodity and spans many chips, grades, tenors, locations, and contract structures. A live prediction market can aggregate those dispersed views into transparent prices that reflect market expectations for different maturities. The opportunity is big. Hyperscalers are spending over $700B on compute this year and the market is expected to grow to $7-10T by 2030. If this market behaves like traditional commodity markets, a liquid derivative market could be 10-20x bigger than the underlying spot market. Compute is still not uniform enough, but this is a step towards standardization as forward curves will help us see the rise and fall of different model prices and how they correlate. The forward curve is a first step. Up next: futures and perps.

Today we're shipping screen-aware dictation. First, we built a speedy speech-to-text (very fast, ~450ms). But, many products do this! So we went further. Now dictate using your screen as context. In Claude Code, it writes the prompt. In G-Mail, it replies in your voice. Demo:

2024: a yc application and a thesis few people were excited about today: - $15m series a - notion, xero, and some of the world's biggest media companies and storefronts trust us with every release - grew from 2 people to 16 - 1,000x more test volume than a year ago - shipped web, android, ios + free self-serve 2 years ago i was burning four hours every thursday manually testing releases, telling myself there had to be a better way this june our agents analyzed 62,052 test failures that's 2,000+ hours nobody had to waste, and a lot of bugs your users never met some mornings i just sit there like… how is this real lol if you're building right now, go chase the problem everyone else already made peace with the fact that nobody's excited about it yet is usually why it might just work out

Today, @UseCorgi is excited to expand into trucking insurance. The U.S. freight trucking industry is projected to be as large as $906B in 2026, yet it is one of the most underserved segments within commercial insurance. Prior to Corgi, trucking companies had to wait days (or even weeks) to get coverage, deal with drawn-out claims settlements and inaccurate pricing due to fragmented data across the many layers (brokers, MGAs, etc.) between the customer and the policy. We combined AI with 30+ years of trucking insurance & underwriting experience to offer: - Commercial auto liability - Cargo insurance (annual/per-load) - Carrier-level service (instant quotes, flexible coverage, claims handling)

Launching @vorfluxai : The autopilot for software engineering. I was prev co-founder / CTO of @Rippling ($10B) and #1 coder in India. Vorflux is my high octane Ferrari. Every AI coding tool still makes you fly the plane. That's the copilot model: you stay in the seat, approving every turn. The models quietly got good enough to fly the whole route, but the tools never caught up. So we built the autopilot. @vorfluxai raised a $15M seed by @ycombinator @peakxvpartners @alliancedao @parkerconrad @jake_zeller @balajis @nivi @metakovan @lmrankhan @nikitabase @0xrwu @ayushjaiswal @mattshumer_ @eshamanideep @sreeramkannan @dvcoolster @nusimow @TeddySolomon11 @ashtoncofer @rvivek etc Drop your biggest engineering bottleneck below. I'll reply with how I'd attack it with Vorflux, and hand you $200 in free credits to bang out your backlog. Our full thesis 🧵👇

Congrats to @JackOswald10 and @singularitydefc on their $80M Series A at a $400M valuation! They're building low-cost missile-based air defense interceptors designed to be produced at automotive scale. The founding team includes alumni of SpaceX, Tesla, Anduril, and Lockheed Martin, alongside operators who sold more than $12B in air defense systems over their careers. They run multiple flight tests a month and are building production lines larger than any comparable US system. tectonicdefense.com/interceptor-st…

I'm excited to finally be able to talk about @JackOswald10, who is building one of the most important companies in the world right now. We've all seen from Iran that not having a scalable air defense system is a critical problem for the US military. That's what Jack and the Singularity team are solving. I first met Jack when he was a student at MIT, but the story goes back way before then. Jack built a 10,000 lb thrust solid rocket motor *in high school*. He spent his undergrad years at MIT working on the Raptor engines at Spacex. He was the first hire at Tom Mueller's startup Impulse Space while still in college. If you tried to imagine the perfect person to start this company, you'd picture Jack. Because this technology is sensitive, Singularity had to stay in stealth for a long time. Over the past two years, they've quietly raised $80M and built one of the best teams in the industry. In particular, they invested early - much earlier than most startups - in building a manufacturing team that knows how to scale low-cost mass manufacturing. The current defense industry is designed to produce a small number of high cost systems, which is why we're in such trouble right now. Only a new company that's built from the ground up for mass production will be able to meet the needs we have now, and that's what Singularity is.

NYC Designers! Super excited to get together for a Happy Hour this Wednesday. If you're a designer that's ever thought about starting a company yourself, or are currently a founder looking to build a culture of first-class design at your startup, this is for you:

Before vibe coding became a thing, programming was already evolving in that direction. It already increasingly consisted of installing and configuring stuff other people wrote, without reading the source.

Introducing Singularity, a defense company focused on protecting people. I'm incredible proud of this team and mission.

introducing screenpipe: it records and learns how you work and turns it into a searchable memory, SOPs, and AI agents open source, local-first, 20K+ GitHub stars, 1,900+ forks, and 130+ contributors

we're excited to launch Prized - Lovable for internal tools unlike other AI builders, your company data is already there: connected, scoped to what you should see, audited on every access. no copy-pasting credentials, no data plumbing. prefer building with your own coding agent? bring it, it plugs into the same governed sandbox. here's the thing: your ops, support, and finance teams are already building tools with AI. straight from company data, no permissions, no audit trail. security is assumed to be fine because it's "just internal." it's not. so we built them a place where it's safe. describe the tool and watch it take shape, ship it in one click, and it deploys behind your company's sign-in
