delivered the opinion
Rеspondent Ross-Simmons, a sawmill, sued petitioner Weyerhaeuser, alleging that Weyerhaeuser drove it out of
business by bidding up the price of sawlogs to a level that prevented Ross-Simmons from being profitable. A jury returned a verdict in favor of Ross-Simmons on its monopolization claim, and the Ninth Circuit affirmed. We granted certiorari to decide whether the test we applied to claims of predatory pricing in
Brooke Group
Ltd. v.
Brown & Williamson Tobacco Corp.,
I
This antitrust case concerns the acquisition of red alder sawlogs by the mills that process those logs in the Pacific Northwest. These hardwood-lumber mills usually acquire logs in one of three ways. Some logs are purchased on the open bidding market. Some come to the mill through standing short- and long-term agreements with timberland owners. And others are harvested from timberland owned by the sawmills themselves. The allegations relevant to our decision in this case relate to the bidding market.
Ross-Simmons began operating a hardwood-lumber sawmill in Longview, Washington, in 1962. Weyerhaeuser entered the Northwestern hardwood-lumber market in 1980 by acquiring an existing lumber company. Weyerhaeuser gradually increased the scope of its hardwood-lumber operation, and it now оwns six hardwood
From 1990 to 2000, Weyerhaeuser made more than $75 million in capital investments in its hardwood mills in the Pacific Northwest. Id., at 159a. During this period, production increased at every Northwestern hardwood mill that Weyerhaeuser owned. Id., at 160a. In addition to increasing production, Weyerhaeuser used “state-of-the-art technology,” id., at 500a, including sawing equipment, to increase the amount of lumber recovered from every log, id., at 500a, 549a. By contrast, Ross-Simmons appears to have engaged in little efficiency-enhancing investment. See id., at 438a-441a.
Ross-Simmons blamed Weyerhaeuser for driving it out of business by bidding up input costs, and it filed an antitrust suit against Weyerhaeuser for monopolization and attempted monopolization under § 2 of the Sherman Act. See 26 Stat. 209, as amended, 15 U. S. C. §2 (2000 ed., Supp. IV). Ross-Simmons alleged that, among other anticompetitive acts, Weyerhaeuser had used “its dominant position in the alder sawlog market to drive up the prices for alder sawlogs to levels that severely reduced or eliminated the profit margins of Weyerhaeuser’s alder sawmill competition.” App. 135a. Proceeding in part on this “predatory-bidding” theory, Rоss-Simmons argued that Weyerhaeuser had overpaid for alder sawlogs to cause sawlog prices to rise to artificially high levels as part of a plan to drive Ross-Simmons out of business. As proof that this practice had occurred, Ross-Simmons pointed to Weyerhaeuser’s large share of the alder purchasing market, rising alder sawlog prices during the alleged predation period, and Weyerhaeuser’s declining profits during that same period.
Prior to trial, Weyerhaeuser moved for summary judgment on Ross-Simmons’ predatory-bidding theory. Id., at 6a-24a. The District Court denied the motion. Id., at 58a-69a. At the close of the 9-day trial, Weyerhaeuser moved for judgment as a matter of law, or alternatively, for a new trial. The motions were based in part on Weyerhaeuser’s argument that Ross-Simmons had not satisfied the standard this Court set forth in Brooke Group, supra. App. 940a-942a. The District Court denied Weyerhaeuser’s motion. Id., at 720a, App. to Pet. for Cert. 46a. The District Court also rejected proposed predatory-bidding jury instructions that incorporated elements of the Brooke Group test. App. 725a-730a, 978a. Ultimately, the District Court instructed the jury that Ross-Simmons could prove that Weyerhaeuser’s bidding practices were anticompetitive acts if the jury concluded that Weyerhaeuser “purchased more logs than it needed, or paid a higher price for logs than necessary, in order to prevent [Ross-Simmons] from obtaining the logs they needed at a fair price.” Id., at 978a. Finding that Ross-Simmons had proved its claim for monopolization, the jury returned a $26 million verdict against Weyerhaeuser. Id., at 967a. The verdict was trebled to approximately $79 million.
Weyerhaeuser appealed to the Court of Appeals for the Ninth Circuit. There, Weyerhaeuser argued that
Brooke Group's
standard for claims of рredatory pricing should also apply to claims of predatory bidding. The Ninth Circuit disagreed and affirmed the verdict against Weyerhaeuser.

In
Brooke Group,
we considered what a plaintiff must show in order to succeed on a claim of predatory pricing under §2 of the Sherman Act.

In a typical predatory-pricing scheme, the predator reduces the sale price of its product (its output) to below cost, hoping to drive competitors out of business. Then, with competition vanquished, the predator raises output prices to a supracompetitive level. See
Matsushita Elec. Industrial Co.
v.
Zenith Radio Corp.,
The first prong of the test — requiring that prices be below cost — is necessary because “[a]s a general rule, the exclusionary effect оf prices above a relevant measure of cost either reflects the lower cost structure of the alleged predator, and so represents competition on the merits, or is beyond the practical ability of a judicial tribunal to control.”
Id.,
at 223. We were particularly wary of allowing recovery for above-cost price cutting because allowing such claims could, perversely, “chil[l] legitimаte price cutting,” which directly benefits consumers. See
id.,
at 223-224;
Atlantic Richfield Co.
v.
USA Petroleum Co.,
The second prong of the
Brooke Group
test — requiring that there be a dangerous probability of recoupment of losses — is necessary because, without a dangerous probability of recoupment, it is highly unlikely that a firm would engage in predatory pricing. As the Court explained in
Matsushita,
a firm engaged in a predatory-pricing scheme makes an investment — the losses suffered plus the profits that would have been realized аbsent the scheme — at the initial, below-cost-selling phase.
We described the two parts of the Brooke Group test as “essential components of real market injury” that were “not easy to establish.” Id., at 226. We also reiterated that the costs of erroneous findings of predatory-pricing liability were quite high because “ ‘[t]he mechanism by which a firm engages in predatory pricing — lowering prices — is the same mechanism by which a firm stimulates competition,’” and, therefore, mistaken findings of liability would “ ‘ “chill the very conduct the antitrust laws are designed to protect.”’” Ibid, (quoting Cargill, supra, at 122, n. 17).

Predatory bidding, which Ross-Simmons alleges in this case, involves the exercise of market power on the buy side or input side of a market. In a predatory-bidding scheme, a purchaser of inputs “bids up the market price of a critical input to such high levels that rival buyers cannot survive (or compete as vigorously) and, as a result, the predating buyer acquires (or maintains or increases its) monopsony power.” Kirkwood, Buyer Power and Exclusionary Conduct, 72 Antitrust L. J. 625, 652 (2005) (hereinafter Kirkwood). Monopsony power is market pоwer on the buy side of the market. Blair & Harrison, Antitrust Policy and Monopsony, 76 Cornell L. Rev. 297 (1991). As such, a monopsony is to the buy side of the market what a monopoly is to the sell side and is sometimes colloquially called a “buyer’s monopoly.” See id., at 301,320; Piraino, A Proposed Antitrust Approach to Buyers’ Competitive Conduct, 56 Hastings L. J. 1121,1125 (2005).
A predatory bidder ultimately aims to exercise the monopsony power gained from bidding up input prices. Tо that end, once the predatory bidder has caused competing buyers
to exit the market for purchasing inputs, it will seek to “restrict its input purchases below the competitive level,” thus “reduc[ing] the unit price for the remaining input[s] it purchases.” Salop, Anticompetitive Overbuying by Power Buyers, 72 Antitrust L. J. 669,672 (2005) (hereinafter Salop). The reduction in input prices will lead to “a significant cost saving that more than offsets the profit[s] that would havе been earned on the output.”

If all goes as planned, the predatory bidder will reap monopsonistic profits that will offset any losses suffered

Predatory-pricing and predatory-bidding claims are analytically similar. See Hovenkamp, The Law of Exclusionary Pricing, 2 Competition Policy Int’l, No. 1, pp. 21, 35 (Spring 2006). This similarity results from the close theoretical connection between monopoly and monopsony. See Kirkwood 653 (describing monopsony as the “mirror image” of monopoly);
Khan
v.
State Oil Co.,
Tracking the economic similarity between monopoly and monopsony, predatory-pricing plaintiffs and predatory-bidding plaintiffs make strikingly similar allegations. A predatory-pricing plaintiff alleges that a predator cut prices to drive the plaintiff out of business and, thereby, to reap monopoly profits from the output market. In parallel fashion, a predatory-bidding plaintiff alleges that a predator raised prices for a key input to drive the plaintiff out of business and, thereby, to reap monopsony profits in the input market. Both claims involve the deliberate use of unilateral pricing measures for anticompetitive purposes. 3 And both claims logically require firms to incur short-term losses on the chance that they might reap supracompetitive profits in the future.
More importantly, predatory bidding mirrors predatory pricing in respects that we deemed significant to our analysis in
Brooke Group.
In
Brooke Group,
we noted that “ ‘predatory pricing schemes are rarely tried, and even more rarely successful.’ ”
And like the predatory conduct alleged in
Brooke Group,
actions taken in a predatory-bidding scheme are often “ ‘ “the very essence of competition.’””
Brooke Group
also noted that a failed predatory-pricing scheme may benefit consumers.
In addition, predatory bidding presents less of a dirеct threat of consumer harm than predatory pricing. A predatory-pricing scheme ultimately achieves success by charging higher prices to consumers. By contrast, a predatory-bidding scheme could succeed with little or no effect on consumer prices because a predatory bidder does not necessarily rely on raising prices in the output market to recoup its losses. Salop 676. Even if outрut prices remain constant, a predatory bidder can use its power as the pre dominant buyer of inputs to force down input prices and capture monopsony profits. Ibid.
C
The general theoretical similarities of monopoly and monopsony combined with the theoretical and practical similarities of predatory pricing and predatory bidding convince us that our two-pronged Brooke Group test should apply to predatory-bidding claims.
The first prong of
Brooke Group’s
test requires little adaptation for the predatory-bidding context. A plaintiff must prove that the alleged predatory bidding led to below-cost pricing of the predator’s outputs. That is, the predator’s bidding on the buy side must have caused the cost of the relevant output to rise above the revenues generated in the sale of those outputs. As with predatory pricing, the exclusionary effect of higher bidding that does not result in below-cost output pricing “is beyond the practical ability of a judicial tribunal to control without courting intolerable risks of chilling legitimate” procompetitive conduct.
A predatory-bidding plaintiff also must prove that the defendant has a dangerous probability of recouping the losses incurred in bidding up input prices through the exercise of monopsony power. Absent proof of likely recoupment, a strategy of predatory bidding makes no economic sense because it would involve short-term losses with no likelihood of offsetting long-term gains. Cf. id., at 224 (citing Matsushita, supra, at 588-589). As with prеdatory pricing, making a showing on the recoupment prong will require “a close analysis of both the scheme alleged by the plaintiff and the structure and conditions of the relevant market.” Brooke Group, supra, at 226.
Ross-Simmons has conceded that it has not satisfied the Brooke Group standard. Brief for Respondent 49; Tr. of Oral Arg. 49. Therefore, its predatory-bidding theory of liability cannot support the jury's verdict.

For these reasons, we vacate the judgment of the Court of Appeals and remand the case for further proceedings consistent with this opinion.
It is so ordered.
Notes
Brooke Group
dealt with a claim under the Robinson-Patman Act, but as we observed, “primary-line competitive injury under the RobinsonPatman Act is of the same general character as the injury inflicted by predatory pricing schemes actionable under § 2 of the Sherman Act.”
If the predatory firm’s competitors in the input market and the outрut market are the same, then predatory bidding can also lead to the bidder’s acquisition of monopoly power in the output market. In that case, which does not appear to be present here, the monopsonist could, under certain market conditions, also recoup its losses by raising output prices to monopolistic levels. See Salop 679-682 (describing a monopsonist’s predatory strategy thаt depends upon raising prices in the output market).
Predatory bidding on inputs is not analytically different from predatory overbuying of inputs. Both practices fall under the rubric of monopsony predation and involve an input purchaser’s use of input prices in an attempt to exclude rival input purchasers. The economic effect of the practices is identical: Input prices rise. In a predatory-bidding schеme, the purchaser causes prices to rise by offering to pay more for inputs. In a predatory-overbuying scheme, the purchaser causes prices to rise by demanding more of the input. Either way, input prices increase. Our use of the term “predatory bidding” is not meant to suggest that different legal treatment is appropriate for the economically identical practice of “predatory overbuying.”
Higher prices for inputs obviously benefit existing sellers of inputs and encourage new firms to enter the market for input sales as well.
Consumer benefit does not necessarily result at the first stage because the predator might not use its excess inputs to manufacture additional outputs. It might instead destroy the excess inputs. See Salop 677, n. 22. Also, if the same firms compete in the input and output markets, any increase in outputs by the predator could be offset by decreases in outputs from the predator’s struggling competitors.
