Augur Built This in 2018. JPMorgan and Goldman Sachs Just Noticed

In 2018 a project called Augur launched on Ethereum with an idea that sounded either visionary or insane depending on who you asked. Anyone, anywhere, could create a market on the outcome of any real-world event. Elections, sports, weather, economics. No permission required. No central authority. Smart contracts would hold the funds, resolve the outcomes, and pay the winners automatically.

Augur struggled. Gas fees on Ethereum made small trades economically irrational. The user experience required a level of technical sophistication that eliminated most potential users before they made their first trade. Liquidity was thin. Markets sat empty. The vision was correct. The infrastructure was not ready.

Fast forward to April 1, 2026. JPMorgan CEO Jamie Dimon told CBS that his bank is considering entering prediction markets. Goldman Sachs CEO David Solomon had already told investors in January that he personally met with the two dominant platforms in the space to evaluate entry. Polymarket carries a $20 billion valuation. Kalshi hit $22 billion. The sector processed $21 billion in monthly volume.

The idea Augur built in 2018 is now one of the hottest product categories in finance. The question worth asking is what happened in between.

The Eight Year Gap

Augur’s co-founder later described the platform’s early problems plainly: low liquidity, poor user experience, and regulatory uncertainty created a mismatch between product and market. He called the early focus “innovation theater,” a version of decentralization that worked in theory and failed in practice.

What Augur got right was the core concept. Prediction markets aggregate information from people willing to put money behind their beliefs. When enough people trade on outcomes, the market prices reflect something closer to collective probability than any individual analyst can produce. The 2024 US election proved this more visibly than anything before it. Prediction markets called the outcome earlier and more accurately than traditional polling. That moment gave the entire sector its proof of concept.

What Augur got wrong was the execution layer. Polymarket built on Polygon instead of Ethereum mainnet, which gave it lower fees and faster settlement. It denominated everything in USDC at clean one-dollar pricing. It focused on a handful of high-liquidity markets rather than trying to support everything. These were not revolutionary innovations. They were pragmatic choices that Augur’s idealism had prevented it from making.

What the Numbers Look Like Now

The sector’s growth in the past eighteen months is difficult to overstate.

Polymarket set a single-day volume record of $425 million on February 28, 2026, surpassing even its Election Day 2024 peak. The driver was the Iran conflict. A single market asking whether the US would strike Iran attracted $73 million in February alone, the largest geopolitical contract in Polymarket’s history. When traditional financial markets closed for the weekend and equities stopped trading, prediction markets kept running. That 24/7 availability, which looked like a niche feature in 2018, turned out to be a structural advantage during a period of continuous geopolitical shock.

Google Finance began embedding live Polymarket and Kalshi odds directly into its interface. Prediction market prices started appearing in mainstream news coverage. Robinhood integrated event contracts into its platform and gave its 27 million funded brokerage accounts access to the category for the first time. Super Bowl markets alone exceeded $1 billion in volume.

Coinbase added prediction markets. Then came the institutional signal that changed everything. ICE, the parent company of the New York Stock Exchange, announced a strategic investment of up to $2 billion in Polymarket in October 2025. When the company that owns the NYSE decides prediction markets are worth $2 billion of its capital, the category has crossed a threshold.

Why JPMorgan and Goldman Are Moving Now

Jamie Dimon drew clear lines around what JPMorgan would not do. No sports markets. No political betting. Strict controls on insider information. But the fact that he is discussing it publicly at all is the signal. Banks do not explore new product categories when they expect those categories to shrink.

Goldman Sachs is further along. CEO David Solomon told investors he personally spent hours with Polymarket and Kalshi leadership and has a team evaluating the space. The CFTC published a notice in March 2026 seeking public feedback on prediction market regulation, with a comment period running through April 30. Banks typically wait for regulatory clarity before launching new products. The CFTC notice suggests that clarity is approaching.

The fundamental appeal for Wall Street is information. Prediction markets price probabilities in real time across thousands of events simultaneously. For a bank that trades on information, access to a liquid, transparent probability market for geopolitical outcomes, economic data releases, and policy decisions is genuinely useful. Dimon framed most retail activity as closer to gambling. For institutional users the framing is different. It is a hedging tool.

What Happened to Augur

Augur did not die. It pivoted.

Rather than competing with Polymarket and Kalshi for retail users, Augur abandoned the consumer exchange model entirely in 2025 under the guidance of the Lituus Foundation. It now operates as a B2B cross-chain truth layer, an oracle protocol that other decentralized applications can pay to use for resolving real-world outcomes. Any DeFi protocol, prediction market, or smart contract that needs to verify what actually happened in the real world can use Augur’s cryptoeconomic resolution system to get an answer that cannot be manipulated.

The Augur co-founder’s retrospective analysis was honest about what went wrong and what the lesson is. Prediction markets needed to solve the oracle problem and remove user barriers before worrying about decentralization. Build the centralized prototype first. Prove the market exists. Then decentralize. Augur did it in the wrong order.

Polymarket proved the market exists. Now Goldman Sachs and JPMorgan want in. And Augur, the project that started it all, is quietly powering parts of the infrastructure that will settle the contracts those banks will eventually offer.

The idea was right in 2018. The world just needed eight more years to catch up.
