Everybody’s talking about prediction markets — here’s what you need to know

Scott Kominers, Alex Tabarrok, and Sonal Chokshi

Prediction markets are a hot topic again — even cartoon characters are talking about them (thanks, South Park?). But beyond the buzz, what is a prediction market, exactly? How do they work, how are they designed, and what makes them work?

We tease apart the signal vs. the noise in this deep-dive episode featuring experts Alex Taborrok (professor of economics at George Mason University) and Scott Kominers (a16z crypto research partner and Harvard Business School professor), in conversation with Sonal Chokshi. While we originally covered this topic during last year’s election, the discussion is more relevant than ever today, as we go into the claims people make about prediction markets — what they’re good for (and not); how they fit in with other trends like AI, futarchy, and the crisis in scientific publishing; and where blockchains/ crypto comes in.

This is your definitive explainer on the topic; listen (or read it) here.


COMPANY BUILDING

Advice for founders: Stop trying to get preempted

Arianna Simpson

The “not-raising-raise” playbook for fundraising became very popular a few years ago. That time (2020-2021) represented a very different market and environment: The IPO market was hot, stocks were ripping, and interest rates were near zero; it was hard to distinguish strong fundamentals from ZIRP phenomena.

But a lot of startup founders are still opportunistically taking VC meetings today, hoping to be preempted in their fundraising round, even if they aren’t officially raising (they’re “heads down building”). The problem is this strategy doesn’t work out for most of those founders. The best way to know you’re being preempted? There’s a term sheet in your inbox. Short of that, you’re really being asked to run a fundraising process with a single bidder.

The founders who are seeing the most success in fundraising today are the ones who have rediscovered the lost (pre-2020) art of traditional venture capital pitching: A structured, intentional process. read more

On hiring: When and when isn’t blockchain experience essential?

Ian Dutra and Craig Naylor

As the crypto industry grows, and creates a greater demand for talent, one of the biggest questions that comes up is — whether you need to hire someone who has crypto-native experience, or hire someone who can learn the industry?

It’s the source of endless internal debates. But there are well-established practices you can draw on to find the right people with the right skillsets. That’s what this guide is for: to help founders and recruiters determine where crypto experience is crucial; where other kinds of experience can have the biggest impact; and what challenges and considerations need to be addressed along the way. read more

INDUSTRY NEWS AND UPDATES

Research: The latest on congestion pricing, carpooling, and commuter welfare

Everyone hates traffic. So where and how does congestion pricing — which extends from city blocks to, yes, blockchains — come in? We covered this topic on our podcast earlier this year with Michael Ostrovsky of Stanford University’s Graduate School of Business and the National Bureau of Economic Research. Now, Ostrovsky, with Michael Schwarz (of Microsoft) share in a just-released paper their latest findings that carpooling and road pricing can be “much more effective jointly than each one separately”, and without having to rely on redistributing government revenue.

To learn more about congestion pricing — the economics, the theory, the reality — check out our episode with Ostovsky, as well as a16z crypto’s Scott Kominers and Robert Hackett, here.

Industry news

Morgan Stanley will offer cryptocurrency trading on its E*Trade platform through a partnership with Zerohash in 2026, according to Reuters. E*Trade clients will initially be able to trade bitcoin, ether, and solana.

Fold announced earlier this week that it is launching a bitcoin rewards credit card by integrating with Visa’s global payments network and Stripe’s issuing infrastructure. Unlike other reward programs, as reported in Yahoo Finance, Fold’s system will “be entirely Bitcoin-based, without token lock-ins, staking requirements, or complex redemption processes”.

Coinbase and CloudFlare announced they’re creating a foundation to support x402 protocol adoption. By embedding payments directly into the web using the HTTP 402 “payment required” protocol code, x402 is intended to be a “universal standard for AI-driven payments”, according to Coinbase, ushering in “a new era of automated, scalable commerce”.

x402 allows clients and services on the web — from AI agents, APIs, and apps — to directly exchange data on the web. CloudFlare outlines how the transaction flow works step-by-step in this post, but the key point is that specific clients and servers are able to transact without the need for accounts, subscriptions, or API keys. In other words: “transact value, not just exchange information”. Early use cases outlined by Coinbase include pay-per-use, pay-as-you-go, and pay-per-content for AI, real-time analytics, storage and compute, tipping for content, and of course… agentic commerce.

CloudFlare also introduced a new dollar-backed stablecoin to enable “instant, secure” transactions for the agentic web.

Around the web

On the importance of full-stack openness and verifiability, by Vitalik Buterin — excerpts below:

Perhaps the biggest trend of this century so far can be summarized by the phrase ‘the internet has become real life’…

The civilizations that gained the most from new waves of technology are not the ones who consumed the technology, but the ones who produced it… This future involves a lot of trust being put in technology. If that trust is broken — through backdoors, security failures — we get really big problems. Even the mere possibility of that trust being broken forces a fallback to fundamentally exclusionary social models of trust (‘Was this thing built by people I trust?’).

Avoiding these problems requires technology across the software, hardware, and bio stack that has two intertwined properties:

  1. Genuine openness — open source, including free licensing; and
  2. Verifiability — including, ideally, directly by end users.”
