Prediction Markets and The Beauty of Crowds

To investors,

Below is a write-up from Sebastian Deri and the team at Polymarket, the largest blockchain-based information markets platform. They explain what information markets are and how they can be leveraged to get some of the highest quality news on major world events like COVID-19.

Why You Should Get Your News From the Blockchain

On Wednesday, July 21st, the BBC ran an article that Toshiro Muto, the head of the 2020 Tokyo Olympics organizing committee, had not ruled out cancelling the Olympics, which was scheduled to begin that Friday, two days later. Would the Tokyo Olympics actually be cancelled just days before it was set to start? Or was this all hot air? Wouldn’t it be nice to be able to cut through the B.S. and know what is likely to happen?

At Polymarket, we think this is yet another use of the blockchain: financially incentivizing the truth.

For those that don’t know, Polymarket is the world’s largest crypto-based information markets platform, built on Layer 2 of the Ethereum blockchain. In an information market, you trade on whether events will happen. For example, an event might be -- “Will the 2020 Tokyo Olympics take place as scheduled?” And then one can buy a “Yes” share, which pays out $1 if the Olympics take place as scheduled and $0 otherwise (vice versa for “No” shares). Until the truth is known, the shares trade at their expected probability of happening, so a “Yes” share trading at $0.85 cents indicates that the market believes there is an 85% chance that the Olympics will take place as scheduled.

These markets, which can be created in realtime, are how the blockchain can be used to financially incentivize the truth. The coronavirus pandemic provides a perfect example of this.

COVID at the Olympics

As early as April, three months before the announcement of a possible cancellation, our platform had a market on whether the Olympics would take place as scheduled. From the very beginning, the odds of “Yes” were trading at 85%, indicating that it was very likely that the Olympics would indeed be held, as scheduled, global pandemic notwithstanding. On the day of the announcement of a possible cancellation, the odds of “Yes” had climbed to 98%, and continued to stay right there in the hours and days after the announcement. In other words, the possible cancellation was just a bunch of hot air, likely meant to appease a group of Japanese residents protesting holding the Olympics due to spiking Covid cases in Japan. Indeed, in the end, the Olympics did end up taking place as scheduled. The dozens of articles about the possible cancellation and the hand wringing that followed could have been safely ignored with a glance at the market.

The Delta Variant and Third Wave

Sometimes, the opposite is the case. The news is slow to cover or give full attention to something that information markets are already reacting to. An example of this is the emergence of the Delta variant of the coronavirus, which eventually would lead to a third wave spike in Covid cases.

From June and into the first week of July of 2021, daily Covid cases were at record lows. From record highs of 100-200k daily cases in January of 2021, daily cases were down to around 10-15k cases in June and July. Indeed, on July 10th, 2021, daily Covid cases were at 20k, and the front page article of the New York Times was about new CDC guidance pushing for a full reopening of schools in the coming months. It seemed like the virus might be winding down and we would be returning to pre-pandemic life.

However, as a hedge that things really were returning to normal, a market was launched on Polymarket on July 9th, 2021, asking the simple question -- “Will there be any day before the end of the year, where daily cases would spike to 100k or higher?” Any day with 100k or more cases would indicate the Delta variant was a serious threat, likely to bring us back to winter peak levels of Covid. If that wasn’t on the horizon, then the odds of “Yes” on the market should have been trading very low - say, below 10%.

This wasn’t what we saw. By the end of the day, on July 9th, the first day the market was open, the odds of “Yes” were at 65%. This indicated that the market thought it was more likely than not that we’d see a return similar to the winter peak/second wave levels of Covid.

Meanwhile, the news was lagging behind this emerging threat. Below is a chart of the New York Times frontpage headlines against the Polymarket odds. After the initial headline about reopening, there wasn’t another leading story about Covid until July 23rd, 2021. By that time, the market odds were at 92% “Yes” that we’d see a third wave ushered in by the Delta Variant. Once it was on the front page of the New York Times, it was already a done deal.

By August 3rd, the reality that the markets had predicted hit. There were days with over 100k cases. Indeed, by that point, there was already another market up (which is still actively trading) on whether there would be any day before October 1, 2021 with 200k cases.

The news was unfolding on Polymarket and discussed in our Discord server, just not in the headlines.

And even traditional financial markets were lagging behind our platform. It wasn’t until the morning of Monday, July 19th, 2021, that markets woke up to a drawdown, that was widely attributed to the rapidly increasing covid cases. That morning, the Dow, NASDAQ, and S&P 500 all opened 1% down, and closed the day, even further down, with the Dow seeing its biggest single day loss the whole year at that point.

Unlike traditional financial exchanges, which only operate during certain hours, and on certain days of the week, trading on Polymarket is open 24 hours a day, 7 days a week, 365 days a year.

While investors in traditional markets had to wait for the markets to open on Monday, July 19, traders on our platform could continue to check the odds of a huge spike over the weekend as well. Indeed, this is likely why Patrick Collision, CEO and co-founder of Stripe, and one of the most respected minds in finance, was quoting our market odds on Sunday, July 18th, 2021, to get a better handle on the emerging spike in cases.
