Why The Boring Company’s $10 million dollars per mile price tag is a game changer
With The Boring Company, Elon Musk hopes to overcome the pitfalls that drive up the costs of underground rail transport construction using good old-fashioned innovation with a dash of Silicon Valley startup dust (dirt?). Currently, most U.S. local and state governments (i.e., tax payers) hand over an average of $200-$500 million dollars per mile to construct a subway system, with hundreds of millions more per mile a common occurrence and even a $1 billion dollars per mile price tag having happened a few times already. The reasons for such expense seems to be multi-faceted and stubborn: regulations, unions, and project management. So, when the Tesla CEO and Boring Company founder cited $10 million dollars as the final price of their mile-long demonstration tunnel, including internal infrastructure, lighting, comms/video, safety systems, ventilation, and tracks, he seemed to be threatening to completely upend yet another industry, this one having been at the core of transportation for nearly 200 years.
“I like trains, by the way. I really like trains a lot,” Musk assured his press audience at the company’s recent demonstration tunnel opening event. The Boring Company (TBC) began as a Twitter discussion wherein the tech mogul was venting about “soul-destroying” traffic in Los Angeles. A concept animation followed soon after (as well as hats and not-a-flamethrowers), imagining a transportation system where cars would be shuttled around at high speeds underground on electric skates. Ideas flowed, tunneling began, and the result of all those efforts went on display December 18, 2018, demo rides included. A rideable 1.14 mile tunnel had been constructed from Crenshaw Boulevard across from the Hawthorne, California headquarters of SpaceX, Musk’s private rocket company, to the 120th Street/Prairie Avenue crossroad of Hawthorne.
Around this time last year, Brian Rosenthal of the New York Times exposed several astonishing factors that added up to a $3.5 billion dollars per mile cost to construct a 3.5 mile tunnel to connect Grand Central Terminal to the Long Island Rail Road in New York City, aka the “East Side Access”. An infamous “first”, this price tag is 7 times more than the average of anywhere else in the world. A combination of trade union, construction company, and consulting firm practices, including significant staff redundancy, bred an environment ripe for cost pile-ups, and both incompetence and the lack of oversight within New York’s Metropolitan Transportation Authority (MTA) added significantly to the issue. While the specific amount of money spent made the system’s cost unique in the world, the general underlying issues were not uncommon.
New York may be an exception to the already high-cost of rail construction rule, but there’s the rub: It’s already incredibly expensive. As documented in numerous articles by Alon Levy, an independent journalist whose 2011 blog post on the topic inspired the research that eventually led to the Times piece, $100-$500 million dollars per mile is a typical cost for building railed transporation worldwide. “These are crazy numbers,” Musk exclaimed at the tunnel opening event after summarizing the multiple billions of dollars short tunneling projects cost to complete in L.A. and New York. If the building cost wasn’t enough sticker shock, it gets worse: The daily operating costs of rail systems in the U.S. exceed the amount earned.
Another metric that is used to estimate the true cost of rail construction is cost per rider. After the time and money is spent building a public rail system, it needs to be staffed and repaired, expenses which are difficult to match with revenue without a large number of riders. As cited by Alon Levy in an article Elon Musk tweeted recently, New York’s Second Avenue Subway will cost $25,000 per rider to complete 200,000 trips per day. In Los Angeles, the Purple Line will cost $45,000 per rider for 150,000 trips per day as will Boston’s Green Line Extension for 52,000 trips. Looking at rider fares, New York loses a bit less than $1 per ride taken and L.A. loses over $2 per ride.
So, how will The Boring Company “do” underground transportation system building better than the traditional, money-heavy methods? To put it simply: Be efficient.
Building a better mouse snail trap
They’ve designed their tunneling machines to bore faster and more efficiently. While the first generation machine is conventional and named Godot after the Samuel Backett play, Waiting for Godot due to the length of time it took to understand the machine’s functionality and assemble it, two other improved generations will be part of the Boring family.
The second generation machine, named “Line-Storm” after a Robert Frost love poem with the same phrase in its title that’s about overcoming hardships, is a conventional boring machine that has been highly modified. It uses a redesigned cutting head that takes in significantly more dirt and is 2 times faster than Godot.
-
The third generation machine, named “Prufrock”, will be a ground-up, fully designed TBC machine that’s 15 times better than the next best boring system, and that means 15 times faster than the next best machine out there, period.
Improved construction practices and project management
During construction, TBC reinforced tunnel segments as they were dug, those reinforcements being created on-site out of materials comprising 70% of the dirt dug and the remaining 30% primarily cement. This recycled material, as-you-go system enabled quick construction with cost efficiency, the demo tunnel taking 2 years almost to the day from Musk’s initial Tweet that inspired the undertaking.
Function-focused engineering
TBC’s tunnels are smaller than the typical underground rail system because they’re designed for specific types of vehicles that are smaller than traditional transports (autonomous electrics) and don’t require extra space for maintenance. This in itself reduces costs by 3-4 times.
Although The Boring Company has the advantage of being the new kid on the block whose founder has a unique background in shaking up traditional systems, there may still be a few hangups that will never quite go away. Anything involving the general public, especially public transit, will have serious bureaucracy involved. To achieve the company’s mile-long demo track feat, it had to face the extreme regulatory environment of Los Angeles. California overall has earthquakes, is a methane zone, and has oil and gas fields, all which add to a long list of rules to be followed for any construction projects to commence. “The amount of paperwork we had to go through to do this was enormous,” Musk said at TBC’s recent event.
Additionally, a lawsuit filed last year by the Brentwood Residents Coalition and the Sunset Coalition objecting to the company’s Sepulveda tunnel eventually led to their abandonment of that leg of the demonstration project. The coalitions primarily alleged that TBC was skirting environmental review requirements by “chopping large projects into smaller pieces that taken individually appear to have no significant environmental impacts”, citing a conceptual map the company released showing its planned Los Angeles tunnel system. Musk hasn’t let these hurdles damage his confidence, however. While speaking with press at TBC’s opening event, he added his own spin to the Broadway mantra (and Frank Sinatra hit, “New York, New York”) about “making it” there : “If you can build a tunnel in L.A., you can build it anywhere.”
As CEO of an innovative electric car company and a commercial rocket company set on sending humans to Mars, Musk is known as an industry disruptor. Even if the cost of boring tunnels for public transportation projects rises somewhat above the $10 million per mile price demonstrated with the LA/Hawthorne tunnel, it will be still be well under the typical costs in the boring industry. It’s obvious already that a potential disruption is underway. “We have people hounding us to invest nonstop…it’s kinda ridiculous how much interest we’ve had in investing in Boring Company,” Musk stated at the tunnel unveiling. Steve Davis, president of the company, added that they receive “greater than 5 and less than 20 requests per week from different municipalities and stakeholders.”
Also in the works for the tunneling newcomers: A transport line connecting downtown Chicago to Chicago O’Hare International Airport. The company won a contract to build a transport system for the city’s fliers in June 2017, and ground breaking is planned for sometime in the next few months. The Boring Company’s calendar still includes plans for an “urban loop system” as well, an underground network of pod-type buses for pedestrians and cyclists connecting numerous points throughout city centers.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.
– Tesla Model 3 battery and drive units
– Transports 22,000+ lb of concrete segments to the boring machine
– 28 miles of range
– 12 mph max operating speed

The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.

It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.

The Boring Company’s newest Vegas Station has a permit quietly waiting behind it
Sahara Las Vegas opened a new Vegas Loop station, joining an exclusive two resort transit club.
Sahara Las Vegas opened a new Vegas Loop station Thursday, giving The Boring Company’s underground transit system its northernmost stop yet on the Strip. The station sits at Sahara’s Paradise Road entrance, on the southeast corner of Las Vegas Boulevard and Sahara Avenue, and connects riders to the Las Vegas Convention Center, other Strip resorts on the network and, eventually, Harry Reid International Airport.
The addition makes Sahara the second resort, after Fontainebleau opened its own station in January, to get a stop built at street level rather than tucked into the property itself. Sahara now joins Westgate as the only two Strip resorts offering both a Vegas Loop station and a stop on the Las Vegas Monorail, giving guests two separate ways to get around without leaving the property.
The Boring Company just doubled its tunneling power in Nashville
The bigger news buried in Thursday’s announcement is what comes next. Boring Company has already secured its first permit to tunnel north of Sahara Avenue, extending the network beyond where it currently ends, even though permits to push the Loop toward downtown Las Vegas still haven’t been granted. Crews are also working on a two mile dual tunnel line running from Westgate to a planned station at 4744 Paradise Road, just north of Tropicana Avenue, that Las Vegas Convention and Visitors Authority CEO Steve Hill has said the company hopes to open in time for November’s Las Vegas Grand Prix.
Ridership has grown alongside the buildout. The Loop moved roughly 82,000 passengers during CONEXPO in early March, a total the company highlighted on its own X account at the time, and the system has now carried more than 4 million passengers through 11 open stations since it began running in 2021. The airport connector tunnels, meant to give the Loop a direct link to Harry Reid, have slipped past their original first quarter target and remain under construction, with Boring Company director Mike Baier saying that a full opening is still a few months out.
For Sahara, the calculation is straightforward. Convention traffic drives a large share of Loop ridership, and a station at the property’s front door gives conventiongoers one more reason to book rooms on the Strip’s north end instead of closer to the convention center itself.
