Prediction markets have seen some volatile and surprising shifts over the past 48 hours, especially as global political tensions and major corporate events dominate headlines. On Polymarket, the top market by volume has been the question of whether Biden will be the Democratic nominee by November. Trading volume exceeded two million dollars yesterday, and in just the past day, his chances fell from 78 percent to 65 percent. The sharp drop seems directly linked to increased media coverage about possible substitution by governors or Vice President Harris ahead of the convention. Some traders appear to be rebalancing aggressively in response to reports from party insiders casting doubt on Biden’s long-term health for a full campaign.

Over on PredictIt, the Republican vice presidential choice market has also become extremely active. Tim Scott surged earlier this week, climbing from 12 cents to a high of 24 cents, before falling back to 19. Observers are citing strong evidence that Trump's post-debate team is seriously vetting Scott, along with J D Vance and North Dakota Governor Doug Burgum. Vance’s price has stayed relatively stable near 22 cents, with unusual purchase spikes following key fundraising dinners. What’s curious is that Nikki Haley’s price remains below 5 cents, despite polls showing broad general-election support if she were on the ticket. Either traders do not believe Trump would make that pick, or they think the loyalty dynamic rules her out entirely.

Metaculus, which aggregates crowd probabilities rather than running a trading exchange, has shown a notable movement in its Ukraine-related markets. The question of whether Ukraine will control more territory at the end of 2024 than at the start of the year has dropped from 43 percent to 38 percent. This shift appears connected to new reports from the front lines in eastern Ukraine and slow deliveries of promised Western military aid. One surprising note is that the question about whether any NATO country will deploy combat troops to Ukraine by the end of this year has risen from under 5 percent to nearly 11 percent in just three days. For a low-probability event, that is a substantial uptick and likely fueled by recent statements from the French government refusing to rule out such deployments altogether.

One trend that is becoming impossible to ignore is the growing correlation between news events and minute-by-minute price swings. Real-time media coverage may now be impacting markets faster than ever. For instance, when CNN posted a breaking alert about the Justice Department possibly investigating a major tech CEO last night, the Polymarket contract on the CEO being indicted jumped from 18 percent to 33 percent in less than thirty minutes, with over 140 thousand dollars in transactions during that window. What this suggests is that prediction markets are no longer just reflecting public sentiment or long-term data, but are increasingly being used as tools for speculative response to news, almost like a financial betting form of social media.

Speaker 1 (00:00):
Prediction markets have seen some volatile and surprising shifts over
the past forty eight hours, especially as global political tensions
and major corporate events dominate headlines on polymarket. The top
market by volume has been the question of whether Biden
will be the Democratic nominee by November. Trading volume exceeded

(00:20):
two million dollars yesterday, and in just the past day
his chances fell from seventy eight percent to sixty five percent.
The sharp drop seems directly linked to increased media coverage
about possible substitution by governors or Vice President Harris ahead
of the convention. Some traders appear to be rebalancing aggressively

(00:41):
in response to reports from party insiders casting doubt on
Biden's long term health for a full campaign over on predicted.
The Republican vice presidential choice market has also become extremely active.
Tim Scott surged earlier this week, climbing from twelve cents
to a high of twenty four cents before five back
to nineteen. Observers are citing strong evidence that Trump's post

(01:05):
debate team is seriously vetting Scott, along with J. D.
Vance and North Dakota Governor Doug Burgham Vance's price has
stayed relatively stable near twenty two cents, with unusual purchase
spikes following key fundraising dinners. What's curious is that Nicky
Haley's price remains below five cents despite polls showing broad

(01:25):
general election support if she were on the ticket. Either
traders do not believe Trump would make that pick, or
they think the loyalty dynamic rules her out entirely. Metaculous,
which aggregates crowd probabilities rather than running a trading exchange,
has shown a notable movement in its Ukraine related markets.
The question of whether Ukraine will control more territory at

(01:48):
the end of twenty twenty four than at the start
of the year has dropped from forty three percent to
thirty eight percent. This shift appears connected to new reports
from the front lines in eastern Ukraine and slow deliveries
of promised Western military aid. One surprising note is that
the question about whether any NATO country will deploy combat

(02:10):
troops to Ukraine by the end of this year has
risen from under five percent to nearly eleven percent in
just three days. For a low probability event. That is
a substantial uptick and likely fueled by recent statements from
the French government refusing to rule out such deployments altogether.
One trend that is becoming impossible to ignore is the

(02:32):
growing correlation between news events and minute by minute price swings.
Real time media coverage may now be impacting markets faster
than ever. For instance, when CNN posted a breaking alert
about the Justice Department possibly investigating a major tech ceo
last night, the polymarket contract on the ceo being indicted

(02:53):
jumped from eighteen percent to thirty three percent in less
than thirty minutes, with over one hundred forty three thousand
dollars in transactions during that window. What this suggests is
that prediction markets are no longer just reflecting public sentiment
