Ngl, I mainly come to start my morning with violin music as I rush in late to my first meeting

[Proof of Talk @proofoftalk]

The doors are open. Welcome to the Louvre Palace.

A violinist plays at the entrance, and the 2,500 decision-makers start walking in from across the world.

This is the morning we have been working toward all year.

Your year changes here.

Harvard professor Arthur Brooks explains how data shows that the unhappiest and most mentally ill people are mostly on the political left while the happiest are on the right.

Liberal women 18-30 have a 60% chance of being diagnosed mentally ill. Discuss.

At least I didn’t get hit by a meteor today ✅

[Nick Sortor @nicksortor]

🚨 WOW! Another video of the “explosion” in the Boston area really captures how LOUD the boom was

It’s looking like the cause was a “significant” meteor crashing through the atmosphere and burning up, as indicated by heat signatures via satellite, per @NStewWX

This has not yet been confirmed.

Here's how onchain prediction markets market share by revenue currently looks like

Total monthly revenue in May across all four platforms is $30.66M. Polymarket dominates with 86.7% share, Limitless is a distant but meaningful second at 11.6%, and Predict and Opinion together make up the remaining ~1.7%.

Change is always good. See you in Paris next week, @proofoftalk.

Everyone talks about IPO day. We’re going deeper.

Who gets in early? Who pulls the levers? Who wins before trading even begins? What really happens before and after the bell?

@Ferdi_XV @FTDA_US @adam3us @Blockstream @proofoftalk @XVentures_Fund You are a force, Ferdi!! See you soon.

[Keli Callaghan 🛡️ @KeliCallaghan]

My first @proofoftalk was 3 years ago. I landed off a redeye and went straight to the venue and was so energized I was still there and carrying my suitcase around well past dinner.

Looking forward to this event again in just a week! The team does a great job pulling it together for everyone involved.

For a decade, Web3 and TradFi argued.

In 2026, they're sitting at the same table.

In 10 days, Jenny Johnson (CEO @FTDA_US, $1.5T AUM) and @adam3us (Co-Founder, @Blockstream , inventor of Hashcash) open Proof of Talk 2026 on the same stage.

That fireside is the thesis of the entire event.

Hyperliquid has quietly become crypto’s dominant fee engine, capturing 43% of all chain fees (~$11M weekly) as perpetual futures continue to out-monetize nearly every other onchain activity category.

Was not ready for Eric Church to deliver the best commencement speech I’ve ever heard.

Six guitar strings. Six pillars of a life.

Faith. Family. Spouse. Ambition. Community. You.

Tune them when you’re whole, not just when you’re broken.

Watch the whole thing.
