Gambling (incl. prediction markets) right now is approaching opiod-level nightmare plus the bonus of easy money laundering and the occasional thrown election.

Consider when Caesars launched their NY sportsbook, they were awarding $3300 in "free" bets, with an expected value of $1645 (risk free if you coordinated with a partner). That only makes business sense for a highly addictive product. www.yetanothervalueblog.com/p/what-the-f...

To recap, the consensus is now that replay and NBC used stadium clock, but NBC had it ~0.2 ahead on screen (possibly some processing lag, unsure). The play in question ended at 0:01 AND took ~8.5s well under the 9s clock was set to. Need on-cam review and on-field light at zero like basketball.

Just seeing the Big Ten statement with video, and they are clearly ahead of NBC's official stadium clock in the analysis replay. But only ahead by 3 or 4 frames so like 0.1 seconds, not 0.8 like I thought. x.com/bigten/statu... If I'm president, I'm creating NTSB for this kinda stuff.

I can't find a clip, and I can't recall whether the ref said "add one second" or "set the game clock to 9." But they almost always say the latter. So the stadium clock messed up. THAT SAID the stadium clock should be the definitive clock. It's what the players/coaches/refs see!

Noah Goodall @noahgoodall.bsky.social · 06/09/2026
The play in question lasted around 8.5 seconds, well outside the stadium clock's 8.1 seconds but well within Hawkeye's (and the ref's ordered) 9.0 seconds. I am certain this is what happened.

Noah Goodall @noahgoodall.bsky.social · 06/09/2026
I'm so right about this and no one is getting it. Ref ordered clocks to 9. The video review Hawkeye was set to 9.0. The stadium clock though was at 7.1 and they just added a second: it looks like 9, but was actually 8.1. THAT'S the discrepancy. They should show tenths on the stadium clock.

For true savants, watch this better clip (I can't download) and use period key to advance single frames, 30 frames per second. Play is clearly over 0.5s after 0:00, which we know is actually 0.4-0.5s remaining due 9s goof. www.youtube.com/watch?v=7yk6...

Here's the video. The clock was set to 9s by the refs, but it instantly goes to 8s on snap. So you've got to mentally add a second to whatever the game clock is showing. I've added a 9s countdown on snap. The vid cuts off early but you get the idea. Refs probably right to add a play, sadly.

Noah Goodall @noahgoodall.bsky.social · 06/09/2026
I can't find a video of the 2nd to last play of the Michigan game. But watching live, the clock went from 9s to 8s almost immediately on snap, despite the clock having been set to 9s on ref's order. As much as I hate to say this, I think there actually was a sync issue.

Always a "patchwork" of laws, never a beautiful mosaic.
In a statement, Kalshi said that it offered safeguards for customers and that its business model gave people a real opportunity to win money. The company has a “national framework of regulation, not a state-by-state patchwork,” the statement said, adding that it was “overly aggressive for states to try to shut down a federally licensed exchange.”

On the cockfighting, they will probably ban unlawful activity markets, but say nothing about activity that is unlawful here but lawful elsewhere. They would seem to allow these, since they carve out assassinations which are obviously illegal here.

Another thing that I haven't seen mentioned: CFTC won't allow betting on slot machines, but extremely short duration financial markets are effectively random. Kalshi has 15-minute up-down crypto markets. Shorten to 5-seconds, and it's a slot machine legal everywhere, industry's ultimate goal.

Noah Goodall @noahgoodall.bsky.social · 28/07/2026
It's full of weird little nuggets: you can't bet on someone playing a slot machine, but you CAN bet on someone playing poker because that has a skill element. They also have the broadest argument for "economic value" in history, to include single game NBA player point totals.
"In short, to take just one example, the price discovery value of event contracts on how many points a basketball player will score in a game depends on more than whether the event contracts can be used to hedge the purchase price of a ticket to the game. In some circumstances, the prices of those contracts could also, along with other information including the prices of many other event contracts, be factored into models used for commercial forecasting or audience-demand analysis, which are economic questions."

Explanation from Waymo.
"The study’s definition of “serious injury” for TLC crashes only includes injuries that required life-saving medical support. It then compares that TLC data to Waymo’s data, which uses a much more expansive definition of serious injury (‘KABCO’ which is used by NHTSA, NYS DOT and others, and includes things like broken bones) without attempting to control for this difference, which is how at arrived at this misleading conclusion."

Noah Goodall @noahgoodall.bsky.social · 24/07/2026
The safety analysis in the Waymo / taxi / Uber-Lyft comparison report has been removed. Appears to be related to the serious injury / death crashes, which was the only data that made Waymo look bad. static1.squarespace.com/static/5e713...
"As of July 23, 2026, we have temporarily removed our safety analysis
from this report, as well as relevant references to the analysis
throughout the report (denoted in-text by a reference to this section).
We were made aware of data discrepancies between City agency
data for New York City for-hire vehicle crashes with serious injuries
or deaths, as well as City agency data definitions related to such
crashes. We are working to resolve these discrepancies and ensure
our findings properly represent the data and the driving records of
New York City for-hire vehicle drivers and Waymo vehicles. Other
than this section, the remainder of our report remains unchanged."

Strike my earlier comment about taxi/TNC drivers looking good. The injury crash rate is not good for them.

Noah Goodall @noahgoodall.bsky.social · 23/07/2026
Back to the Waymo vs. NYC taxi vs. Uber/Lyft (TNCs) report: this is the money chart. Waymo's injury crash rate looking very good when there is adequate data. The report's framing is way off and misleading in my opinion.
Figure 2 from here: https://static1.squarespace.com/static/5e71380706dc865d40a6f93c/t/6a5a8f5f6ff6a5473092ee00/1784319839886/How+Would+For-Hire+AVs+Impact+NYC_SSTRP_Open+Plans.pdf

Chart recreates data from Table 2.

Noah Goodall @noahgoodall.bsky.social · 23/07/2026
Fatal and serious injury crashes are rare -- Waymo has only seen 3 in 220 million miles. That's why we use the crash / injury crash / airbag surrogates.

Noah Goodall @noahgoodall.bsky.social · 23/07/2026
Glad to see TNC data compared to robotaxis. This is the swap, and the correct benchmark right now. TNC drivers look relatively good. But to be clear, the report found Waymo had lower injury crash rates, and NON-SIGNIFICANT differences in fatal / serious injuries. Authors (and media) are misleading.
Quote reads: " Initial data shows that Waymo vehicles are
involved in fewer injury-causing crashes overall,
but have a significantly higher rate of crashes
with a serious injury or fatality than the existing
New York City for-hire fleet. "

But the data shows non-significant differences, i.e. not statistically significant for fatal and serious injuries. There's just not enough data to make that determination yet.Figure 1 from the report here: https://static1.squarespace.com/static/5e71380706dc865d40a6f93c/t/6a5a8f5f6ff6a5473092ee00/1784319839886/How+Would+For-Hire+AVs+Impact+NYC_SSTRP_Open+Plans.pdf?utm_source=substack&utm_medium=email

Massive error bars, these findings are not statistically significant despite authors' comments and media coverage.

How are Waymos driving into flood waters in Austin? I get that a flat pool of water can look like a road to their sensors. But if they are mapping the entire environment to the cm level, do they not notice the road surface is 10cm higher than it was 2 hours ago?

Listening to an AV America forum, and apparently Waymos in Austin passed school buses with stop arm up 26 times. That's 10x what I'd assumed.

NHTSA needs to do 2 things yesterday: 1. ADS (L4-5) mileage or some kind of exposure data. They refuse to, strawmanning about a "scorecard" like what's NCAP then? 2. Rolling, perpetual NDS at around 3000 cars. Ballpark cost of $50mm per year, probably less given tech advances since 2010.

Safer cars are getting undermined by device usage. NHTSA collects this data by standing on the side of the road and watching drivers stopped at intersections. We really need to reboot a large-scale naturalistic driving study. Phones are VERY different since the the last one ended ten years!

If you have to put this disclaimer in a prediction market, maybe don't have the market.
Damaging or disrupting animal enterprises is a federal crime under the The Animal Enterprise Terrorism Act (AETA) of 2006 (18 U.S.C. § 43). Penalties include fines in excess of $1,000,000 and life imprisonment. Polymarket will cooperate fully with law enforcement in any investigation of interference.

This is interesting only to me, but one of the Tesla crashes had a dog running into the road, and the Tesla positioned itself to the left side of the lane to try and avoid striking it. Which combines two examples I used to give for why risk management in an AV is so much harder than "just brake"!
Both are from https://osf.io/preprints/osf/bzkas_v1

Noah Goodall @noahgoodall.bsky.social · 15/05/2026
I'm curious how often they do remote driving like this, and also what's the per-mile crash rate? Most of what we know of remote ops is from Senator Markey's report, and Tesla's response skipped question 1(f) about latency, so I'd like to know that, too!

Noah Goodall @noahgoodall.bsky.social · 15/05/2026
This is interesting, mainly because Tesla had said they only take control of a vehicle (throttle/brake/steering) as a "last resort" and in both instances there was a Tesla employee in the car, albeit in the front passenger seat per Tesla's policy.

Tesla reports ADS crashes to NHTSA via the Standing General Order. For the Austin robotaxis, they just today unredacted the crash narratives. Most surprising are two instances where the in-vehicle safety monitor asked for a virtual driver, who promptly crashed.

"most prestigious" ... "dimentia"
Those 2,000 requests are just the tip of the iceberg, Howell told ProPublica in an interview. Howell, the executive director of the Oversight Project, estimated that his group had submitted more than 50,000 information requests over the past two years. He described the project as “the most prestigious international investigative operation in the world.”

Among 744 requests that Aamot, Jankowski and Howell submitted to the Department of the Interior over the past year are 161 that seek civil servants’ emails and texts as well as Slack and Microsoft Teams messages that contained terms including “climate change”; “DEI,” or diversity, equity and inclusion; and “GOTV,” an acronym for get out the vote. Many of these FOIAs request the messages of individual employees by name.NHTSA 2024 FOIA logs: "Jankowski,
