Morning digest: October 18, 2026

Nine large U.S. companies, including Broadcom, Verizon, CoreWeave and UnitedHealth, formally objected to tokenized versions of their shares trading on OKXICE, the first real test of the SEC’s new opt-out rule. On crypto venues, weekend bets on chip stocks lost about $52M in 10 minutes while Wall Street was closed. Goldman, Wells Fargo and Morgan Stanley called tokenization a growth opportunity, and HEX founder Richard Heart is in custody in Turkey. Health leads with sodium bicarbonate and guarana in trained or active young men; there are no new brain or cognition studies today. All six Prince William early-voting sites are open today, Sunday, from 11 a.m. to 5 p.m., and Friday, Oct. 23 is the deadline to request a mail ballot or register. Moscow says it downed 127 drones overnight, and two of its airports were restricted for about six hours; Voronezh had alerts but no reported attacks.

Blockchain: companies opt out of stock tokens, chip-stock perps crash on a Saturday, banks embrace tokenization

Nine companies objected to their stock tokens trading on OKXICE. OKXICE, the tokenized-stock venue run jointly by crypto exchange OKX and NYSE owner Intercontinental Exchange (ICE), says nine U.S.-listed companies have formally objected: Cerebras, AppLovin, Applied Digital, Rocket Lab, CoreWeave, Verizon, Applied Optoelectronics, Broadcom and UnitedHealth. Under the SEC’s new innovation exemption, a timely objection from the issuer bars a venue from listing that company’s stock token, so this is the first real test of whether companies will opt out. Applied Optoelectronics told the WSJ it worried about price, liquidity and volatility, and about investors assuming it endorsed an offering it never sponsored. Nasdaq said it will opt out its own shares, because these venues don’t show the best prices in real time or report to the consolidated tape, the official record of U.S. trades. OKXICE says it still plans to list dozens of names, including Nvidia, Apple, Microsoft, Tesla and JPMorgan (The Block; OKXICE notice).

Weekend chip-stock bets lost about $52M in 10 minutes. On Saturday between 5:22 and 5:32 p.m. ET, with U.S. stock markets closed, about $52M of leveraged positions in chip-stock perpetual futures were liquidated. Perpetual futures are contracts with no expiry that track a stock’s price and trade around the clock on crypto exchanges. Roughly $38M of the losses were long positions. The leveraged chip fund SOXL took the biggest hit, about $12.7M, followed by SanDisk and SK Hynix at about $10.8M each. The selling started on Binance and reached Hyperliquid’s Trade XYZ stock contracts in under a second. With no real share price to anchor them, these weekend contracts move only on what crypto traders do to each other; Monday’s open will show how far they drifted (CoinDesk).

Three big U.S. banks called tokenization a growth play, not a threat. On their third-quarter earnings calls, Goldman CEO David Solomon compared tokenization to the move to electronic stock trading and said it means “more products, greater activity,” though he called current activity “small and at the margin.” He said Goldman is looking at running DTCC’s tokenization service at larger scale; DTCC is the main U.S. securities settlement utility. Wells Fargo’s CFO said its tokenized-deposit system is already live for cross-border payments, which land in two minutes or less, though volumes are small, and framed it as a way to win cross-border business without a big overseas branch network. Morgan Stanley said faster-moving assets will raise demand for advice. None gave revenue figures (CoinDesk).

HEX founder Richard Heart was detained in Istanbul. Turkey’s justice minister confirmed on Saturday that Heart, founder of the HEX token and the PulseChain network, was detained on Oct. 14. Police searched 15 addresses and seized $7.15M in cash, six crypto cold wallets, firearms and luxury goods; his wife and three bodyguards were also detained. Heart has been under an Interpol Red Notice since December 2024 at Finland’s request, over suspected tax evasion and assault, and the minister also tied the case to about $1B in alleged crypto fraud in the U.S. and Finland. The SEC’s U.S. case against him was dismissed in 2025. HEX fell about 14% in a day (The Block).

Fidelity found Solana far more resilient, but still concentrated. Fidelity’s Center for Applied Technology reports no Solana mainnet outage in two years and about 99.7% vote success. It also flags the risk of everything failing at once: roughly 20 validator identities control more than a third of stake, one hosting provider runs nearly 29%, about 40% of stake sits in Frankfurt and Amsterdam, and two client builds that share the Agave code base, Jito-Solana and Harmonic, cover about 89% of stake. A single cloud outage or client bug could still stall the chain (Cointelegraph; Fidelity report).

Circle defended USDC’s economics against Open USD. Open USD (OUSD), backed by Coinbase, Stripe and others, passes reserve income to partners after a management fee, and Coinbase is also Circle’s largest USDC distributor. Circle says reserve income also has to pay for redemption, compliance and liquidity. It says standard USDC redemptions stay free, settling in up to two business days, and qualifying Circle Payments Network customers now get free near-real-time redemptions. Circle’s first-half revenue split was covered yesterday (CoinDesk; Circle).

Briefly:

Injective activated fixed gas amounts for supported exchange messages (orders, cancellations, deposits and withdrawals) on mainnet, approved through governance proposal IIP-709, so apps no longer need to simulate each transaction. Gas use becomes predictable, but fees are not fixed: they still depend on the gas price (The Defiant).
Fairshake, the crypto industry’s main super PAC, has spent more than $46M through its affiliate Defend American Jobs against Democrat Sherrod Brown in Ohio’s Senate race; a new FEC filing shows another $5.2M ad buy. Brown is a former Senate Banking Committee chair and a leading crypto critic (Decrypt).
Markets: bitcoin is holding around $81,500 and ether around $2,400, both roughly flat over the weekend (The Block).
No new posts from the Ethereum Foundation or LayerZero since Oct. 16; Glamsterdam still activates on the Hoodi testnet on Oct. 26. No new Swift shared-ledger news either.

Health: bicarbonate and guarana in trained and active young men

Two of today’s studies used trained or physically active young men. The rest come from general older adults or from people with hypertension or obesity, and are labeled as such. There are no new brain or cognition studies today. A second scan of the last 24 hours found nothing else that cleared the bar, and it skipped two widely reported mouse studies, an exercise atlas and a sleep and growth-hormone story, because they don’t support any change in what adults do.

A higher bicarbonate dose added more to sprint intervals in trained basketball players. Forty trained male basketball players (mean age about 21.6) did 4 weeks of preseason sprint interval training, three times a week, on top of regular practice: 4 sets of 10 maximal 5-second sprints, with 20 seconds of active recovery between sprints and 2 minutes between sets. They took 0.3 g/kg or 0.45 g/kg of sodium bicarbonate, or a placebo; a fourth group did no sprint intervals. Both bicarbonate doses improved jump, sprint, change of direction, Yo-Yo intermittent recovery distance and Wingate power more than sprint intervals with placebo, and 0.45 g/kg beat 0.3 g/kg on every measure. For an 80 kg athlete that is about 36 g versus 24 g. The lever: buffering acid during hard intervals may let already-trained athletes get more out of the same sprint sessions. Limits: only 10 per group, men only, 4 weeks, p-values rather than effect sizes in the abstract, and the authors flag stomach discomfort at the higher dose (Journal of the International Society of Sports Nutrition).

Caffeine taken as guarana raised jump power; the same dose of plain caffeine didn’t reach significance. In 18 physically active men (mean age about 21.8), about 5 mg/kg of caffeine as guarana capsules, taken 60 minutes before a 30-second continuous jump test, raised peak power by 4.0% versus placebo (dz 0.82). The same dose as plain anhydrous caffeine did not reach significance. Guarana and caffeine did not differ significantly from each other, so this doesn’t show guarana is better; other “guarana better” differences were descriptive only. It was a single-dose, randomized, double-blind, placebo-controlled crossover with a small sample, men only and a single test (Sport Sciences for Health).

From general and clinical populations:

Ten weeks of breathing exercise or bodyweight HIIT lowered blood pressure in hypertension. Ninety-six adults with hypertension were randomized to control, supervised breathing exercise, high-intensity bodyweight interval training, or both. Versus control, adjusted systolic pressure fell by 18.2 mmHg with breathing exercise, 13.6 mmHg with bodyweight HIIT and 16.3 mmHg with both; diastolic fell by 6.2, 8.0 and 6.7 mmHg. Combining them added nothing over either alone, and quality of life, distress, cortisol, IL-6 and resting heart rate did not differ after adjustment. These are patients, not healthy adults; it is a single, short trial, and the news summary doesn’t give session length or frequency. Published Sept. 23, reported Oct. 17 (Scientific Reports; EMJ).
With lifting three times a week, omnivores gained more muscle than vegetarians. Adults 55 and older (108 people, median age 66) did 12 weeks of resistance training while aiming for at least 1.2 g/kg of protein a day, either lacto-ovo vegetarian (at least 60% plant protein) or omnivorous (at least 60% animal protein). Limb muscle mass rose 0.38 kg on the vegetarian diet and 0.66 kg on the omnivorous diet, so the vegetarian diet was not shown to be non-inferior (difference −0.33 kg, 95% CI −0.69 to 0.03). The vegetarian group also ate less protein, 1.24 versus 1.58 g/kg a day, which may explain part of the gap. Leg press and chair-stand results improved in both groups, with no difference between them. General older adults; diets were self-selected (American Journal of Clinical Nutrition).
Twelve weeks of eccentric training built muscle in adults around 70. Thirty-seven community-dwelling older adults (mean age 70.4) did supervised eccentric training twice a week on an Eccentron device. Muscle mass and thigh and calf girth rose, timed up-and-go and stair-climb performance improved, and biopsies showed higher specific force in type I and IIa fibers. The abstract describes no control group and reports p-values only, and it needs a specialized machine (Scientific Reports).
Water-based resistance training helped one hip-bone site in older women. Ninety-eight overweight older women (mean age 67.5) did supervised aquatic resistance training or land-based elastic-tube training twice a week for 32 weeks, or were controls. The aquatic group improved Ward’s triangle bone density (effect size 0.445) and T-score (0.412) more than both other groups, but most other bone-scan outcomes didn’t differ. It is a secondary analysis of a retrospectively registered trial (Archives of Gerontology and Geriatrics).
Null result: an 8-hour eating window and supervised exercise didn’t beat usual care for liver fat. In the TEMPUS trial, 187 adults with obesity were randomized for 12 weeks to usual care (Mediterranean-diet and activity education), 8-hour time-restricted eating, supervised exercise, or both. MRI liver fat changes didn’t differ from usual care (−0.4% with time-restricted eating, −0.8% with exercise, −1.1% with both; all confidence intervals crossed zero) or between the intervention groups. The comparison group got an active education program, and the trial lasted only 12 weeks (Nature Communications).

General and local

No new Russia sanctions. OFAC has posted nothing since Friday’s Venezuela-related general license, and the Graham Act waivers covered yesterday still stand. Existing sanctions and the rules on transfers and payments to Russia are unchanged (OFAC).

The Fed has gone quiet before its Oct. 28 decision. The pre-meeting blackout runs from Saturday, Oct. 17, through Thursday, Oct. 29, so Fed officials won’t comment. The FOMC meets Oct. 27–28, with the statement at 2 p.m. ET and the press conference at 2:30 p.m. ET on Wednesday, Oct. 28; hike odds are still about 15% (Federal Reserve). It is a light data week: the NAHB housing index Monday at 10 a.m., September housing starts Tuesday at 8:30 a.m. and pending home sales at 10 a.m., jobless claims Thursday at 8:30 a.m., and flash PMIs and final University of Michigan sentiment Friday morning, all ET (Kiplinger).

Gas keeps easing, diesel keeps rising. AAA has Virginia regular at $4.073, down from $4.086 yesterday and $4.178 a week ago, against a national average of $4.299. Virginia diesel rose to $6.283, now 10.5 cents below its Sept. 22 record of $6.388. In the Northern Virginia metro, regular is $4.140 and diesel $6.378 (AAA).

Prince William County and Manassas: All six early-voting sites are open today, Sunday, Oct. 18, from 11 a.m. to 5 p.m.: the Office of Elections in Manassas, the AJ Ferlazzo Building in Woodbridge, Brentsville Courthouse in Bristow, the Woodbridge DMV, Dumfries Community Center and the Haymarket Gainesville Library. Next Sunday, Oct. 25, has the same hours. Friday, Oct. 23 is the deadline to request a mail ballot (by 5 p.m.) and to register or update your registration for a regular ballot (PWC Votes; Virginia Department of Elections). The county’s turnout dashboard hasn’t updated since Oct. 16. The Board of County Supervisors meets Tuesday, Oct. 20, at 2 p.m. in Woodbridge to adopt its 2027 legislative agenda; a Bristow resident’s public comment asks the Board to widen the agenda’s data-center sound-study item to cover the high-voltage substations that serve data centers, citing NOVEC’s Diamond Hill substation. Online comments close at 1:05 p.m. that day (PWC Board agenda). There is still no published outcome from the Oct. 13 tax-policy work session. In Dumfries, the town council voted 7-0 to accept $7M in state funds for Route 1 corridor work and is moving to twice-weekly trash pickup; a town hall on Flock license-plate cameras grew heated (Potomac Local).

Fairfax County: On Oct. 15, a Fourth Circuit panel voted 2-1 to revive the lawsuit by Fairfax and Arlington schools over federal funds withheld because of their transgender-student policies. It sent the case back to district court without ruling on the merits (FFXnow). Police are investigating two Friday-night pedestrian crashes with life-threatening injuries, at South George Mason Drive and Leesburg Pike, and at Route 29 and Blake Lane (WJLA).

Russia: 127 drones over Moscow, two airports restricted; Voronezh quiet

Mayor Sobyanin reported 127 drones downed on approach to Moscow between 22:55 on Oct. 17 and 04:37 on Oct. 18 Moscow time, with no casualties reported; Vnukovo and Domodedovo were restricted from 22:56 until 04:40, the third straight day of Moscow airport disruption. In Voronezh region, Gov. Gusev lifted the drone alert in place since Saturday evening with no reported attacks, and an overnight missile alert lasted just over an hour. Mobile internet was cut again in Moscow and dozens of other regions on Saturday, and WhatsApp and Telegram aren’t on the allowed list, so regular calls or SMS are the surest way to reach family (regions.ru; Voronezhskie Novosti; NEWS.ru).

Bottom line

Big companies are starting to refuse tokenized versions of their stock, even as the biggest banks lean into tokenization, and Saturday’s $52M chip-stock wipeout shows how far weekend contracts can move with no real market to anchor them. There is nothing new on Russia sanctions or transfers, the Fed is silent until Oct. 28, and diesel is about a dime below its record. In Health, the lever worth noting is sodium bicarbonate with sprint intervals for already-trained athletes, with stomach comfort as the limit. Prince William’s six early-voting sites are open today from 11 to 5, and Friday is the mail-ballot and registration deadline. If you’re calling family in Moscow, use a regular call or SMS during internet outages.
