SpaceX is set to debut on Nasdaq tomorrow, the largest IPO in history at a $135 IPO price with a $1.77T target valuation. Crypto derivatives markets have been pricing it for weeks. What does the market think @SpaceX is worth?
We built a dashboard to track pre-IPO perp market data in real time, including pricing, liquidity and open interest.
Check it out to here see what the market is reflecting ➡️ ow.ly/kB4k50ZavCI

It turns out great DevEx helps humans, but AI even more.
If you want AI to speed up software development, you need fast feedback that your changes are correct.

AI coding is here to stay, but it is far from obvious how to get the most value out (rather than tokenmax'ing lol). Ignoring them would be like ignoring git 15 years ago!
Luca and I explored how AI tooling is "forcing" best practices in SW (good CI, fast testing, etc), discussed the challenges of getting teams to adapt (productively!) to new tools, how these tools are challenging OSS projects and proprietary SW moats, among many other topics.
It was wonderful to spend time with Luca talking about the evolving nature of software design. He is thoughtful and does wonderful work at refactoring.fm/, check it out!

Talos increasingly sits at the intersection of traditional capital markets and digital assets. Today, we're proud to announce we're partnering with @Nasdaq to connect Talos’s digital asset infrastructure with Nasdaq’s Calypso and Trade Surveillance platforms.
➡️ Read the announcement: ow.ly/WHq950Yx2e9
🎙️ “This partnership solves a fundamental challenge facing institutional markets: the inability to manage exposure across markets with a single risk and asset lens.”
— Roland Chai, Executive Vice President, Nasdaq
🎙️ “By combining Talos’s digital asset infrastructure with Nasdaq’s Calypso and Trade Surveillance platforms, firms can connect workflows for execution, risk, collateral and compliance to reduce operational friction across both on- and off-chain asset classes.”
— @KatzAnton, CEO and Co-Founder, Talos

It’s always great to be back at @Cornell for our CTO Ethan Feldman and Engineer Zachary Shine.
During this Talos TechTalk, Ethan and Zack shared how we design institutional grade trading infrastructure that must be low latency, handle peak bursts of activity, and run 24/7 with no downtime — because crypto markets never sleep.
The talk focused on our sequencer based architecture and how building services as replicated state machines enables us to build systems that combine performance, determinism, and fault tolerance.
Enjoy this stuff? We’re hiring ➡️ ow.ly/2MYs50YpS3A

Worries that software developer jobs are going away are backwards. There is SO MUCH software to build right now, that previously wasn't possible (uses AI directly) or wasn't cost-effective (too niche). We're going to have more developers, and orders of magnitude more software.

Performance Hints
Over the years, my colleague Sanjay Ghemawat and I have done a fair bit of diving into performance tuning of various pieces of code. We wrote an internal Performance Hints document a couple of years ago as a way of identifying some general principles and we've recently published a version of it externally.
We'd love any feedback you might have!

Talos has integrated its OEMS with BlackRock's Aladdin® platform to expand institutional digital asset order management capabilities for Aladdin users.
This integration unlocks greater efficiency for institutional trading. BlackRock’s team executed over $1 billion in trading volume through the Talos platform in the first week of implementation.
🎙️ “Integrating Talos into Whole Portfolio applications on the Aladdin platform enables us to expand and further automate our crypto trading capabilities. Talos’s crypto-native technology strengthens our execution capabilities now, ensuring we’re ready to meet future client demand with greater efficiency, liquidity access, and execution quality.” -- Daniel Veiner, Head of Markets at @BlackRock
🎙️ "As large, traditional firms move from exploration to execution on their digital asset strategies, they expect the same level of sophistication they’re accustomed to in traditional markets.
